Prolonged mating in prairie voles (Microtus ochrogaster) increases likelihood of ovulation and embryo number. (1/710)

Prairie voles are induced ovulators that mate frequently in brief bouts over a period of approximately 24 h. We examined 1) impact of mating duration on ovulation and embryo number, 2) incidence of fertilization, 3) temporal pattern of embryo development, 4) embryo progression through the reproductive tract over time, and 5) embryo development in culture. Mating was videotaped to determine first copulation, and the ovaries were examined and the reproductive tracts flushed at 6, 8, 10, 12, 16, 20, and 24 h and 2, 3, and 4 days after first copulation. The number of mature follicles and fresh corpora lutea and the number and developmental stage of embryos were quantified. One, two-, and four-cell embryos were cultured in Whitten's medium. Mature follicles were present at the earliest time examined (6 h). Thirty-eight percent of females that had been paired for < 12 h after the first copulation ovulated, whereas all females paired >/= 12 h after the first copulation ovulated. Virtually all (> 99%) oocytes recovered from females paired for >/= 12 h after first copulation were fertilized. Pairing time after first copulation and mean copulation-bout duration were significant (p < 0.05) determinants of embryo number. Embryos entered the uterine horns and implanted on Days 3 and 4, respectively, after first copulation (Day 0). Embryos cultured in vitro underwent approximately one cell division per day, a rate similar to that in vivo. We conclude that prairie voles ovulate reliably after pairing for >/= 12 h, although some females showed exceptional sensitivity not predicted by the variables quantified. Prolonged mating for longer than 12 h increased the total embryos produced. This mechanism likely has adaptive significance for increasing offspring number.  (+info)

A new picornavirus isolated from bank voles (Clethrionomys glareolus). (2/710)

A previously unknown picornavirus was isolated from bank voles (Clethrionomys glareolus). Electron microscopy images and sequence data of the prototype isolate, named Ljungan virus, showed that it is a picornavirus. The amino acid sequences of predicted Ljungan virus capsid proteins VP2 and VP3 were closely related to the human pathogen echovirus 22 (approximately 70% similarity). A partial 5' noncoding region sequence of Ljungan virus showed the highest degree of relatedness to cardioviruses. Two additional isolates were serologically and molecularly related to the prototype.  (+info)

Granulated metrial gland cells and interstitial trophoblast in the uterine wall of the bank vole, Clethrionomys glareolus, in early pregnancy. (3/710)

The morphology and distribution of granulated metrial gland cells and of interstitial trophoblast cells in the uterine wall was studied in the first half of pregnancy in the bank vole, Clethrionomys glareolus. The morphology and distribution of granulated metrial gland cells was generally similar to that found in other members of the Rodentia, although they were absent from the walls of the arterial vessels passing through the decidua basalis. Interstitial trophoblast invaded the decidualising endometrium mesometrial to, and antimesometrial to, the implanted embryos. There was no apparent spatiotemporal relationship between the distribution of granulated metrial gland cells and interstitial trophoblast cells.  (+info)

Rats of the genus Rattus are reservoir hosts for pathogenic Bartonella species: an Old World origin for a New World disease? (4/710)

Bartonella species were isolated from the blood of 63 of 325 Rattus norvegicus and 11 of 92 Rattus rattus from 13 sites in the United States and Portugal. Infection in both Rattus species ranged from 0% (e.g., 0/87) to approximately 60% (e.g., 35/62). A 337-bp fragment of the citrate synthase (gltA) gene amplified by polymerase chain reaction was sequenced from all 74 isolates. Isolates from R. norvegicus were most similar to Bartonella elizabethae, isolated previously from a patient with endocarditis (93%-100% sequence similarity), followed by Bartonella grahamii and other Bartonella species isolated from Old World rodents (Clethrionomys species, Mus musculus, and Rattus species). These data suggest that Rattus species are a reservoir host for pathogenic Bartonella species and are consistent with a hypothesized Old World origin for Bartonella species recovered from Rattus species introduced into the Americas.  (+info)

Isolation and characterization of a hantavirus from Lemmus sibiricus: evidence for host switch during hantavirus evolution. (5/710)

A novel hantavirus, first detected in Siberian lemmings (Lemmus sibiricus) collected near the Topografov River in the Taymyr Peninsula, Siberia (A. Plyusnin et al., Lancet 347:1835-1836, 1996), was isolated in Vero E6 cells and in laboratory-bred Norwegian lemmings (Lemmus lemmus). The virus, named Topografov virus (TOP), was most closely related to Khabarovsk virus (KBR) and Puumala viruses (PUU). In a cross focus reduction neutralization test, anti-TOP Lemmus antisera showed titers at least fourfold higher with TOP than with other hantaviruses; however, a rabbit anti-KBR antiserum neutralized TOP and KBR at the same titer. The TOP M segment showed 77% nucleotide and 88% amino acid identity with KBR and 76% nucleotide and 82% amino acid identity with PUU. However, the homology between TOP and the KBR S segment was disproportionately higher: 88% at the nucleotide level and 96% at the amino acid level. The 3' noncoding regions of KBR and the TOP S and M segments were alignable except for 113- and 58-nucleotide deletions in KBR. The phylogenetic relationships of TOP, KBR, and PUU and their respective rodent carriers suggest that an exceptional host switch took place during the evolution of these viruses; while TOP and KBR are monophyletic, the respective rodent host species are only distantly related.  (+info)

Maternal effort and male quality in the bank vole, Clethrionomys glareolus. (6/710)

Parental investment in reproduction is adjusted according to potential benefits in terms of offspring survival and/or mating success. If male quality affects the reproductive success of a female, then females mating with high-quality males should invest more in reproduction. Although the subject has been of general interest, further experimental verification of the hypothesis is needed. We studied whether female bank voles (Clethrionomys glareolus) adjusted their maternal effort according to male quality, measured as mating success. To enable the measurement of maternal effort during nursing separately from male genetic effects the litters were cross-fostered. Further, the genetic background of male quality was examined. Male quality did not correlate with litter size or offspring size at birth. Offspring growth was positively related to food consumption and milk production of mothers. However, these direct measurements of maternal effort were independent of male quality. Male mating success appeared to be significantly heritable indicating that there are genetic benefits. Still, females did not adjust maternal effort according to the genetic quality of their offspring. We suggest that female bank voles gain significant genetic benefits from mating with high-quality males whereas they cannot improve their reproductive success by increasing maternal effort.  (+info)

Cowpox: reservoir hosts and geographic range. (7/710)

It is generally accepted that the reservoir hosts of cowpox virus are wild rodents, although direct evidence for this is lacking for much of the virus's geographic range. Here, through a combination of serology and PCR, we demonstrate conclusively that the main hosts in Great Britain are bank voles, wood mice and short-tailed field voles. However, we also suggest that wood mice may not be able to maintain infection alone, explaining the absence of cowpox from Ireland where voles are generally not found. Infection in wild rodents varies seasonally, and this variation probably underlies the marked seasonal incidence of infection in accidental hosts such as humans and domestic cats.  (+info)

Potentiation of carbachol-induced amylase release by propionate in guinea pig and vole pancreatic acini. (8/710)

The action of propionate, one of the major end products of microbial fermentation in herbivores was investigated in isolated, perifused pancreatic acini of guinea pigs, voles, and mice. With the use of guinea pig acini, 100 microM propionate had no effect, whereas 300 and 600 microM increased amylase release by six- and ninefold, respectively. Simultaneous perifusion of carbachol (CCh) 10 microM plus propionate 100 microM in guinea pig acini produced a potentiated secretory response that was 130% higher than the summated value obtained with CCh and propionate alone. The potentiation by propionate (100 microM) of CCh (10 microM)-induced amylase release was also obtained in vole pancreatic acini, but the mouse pancreatic preparation did not exhibit a similar potentiation. In contrast to CCh, propionate (100-600 microM) alone had no significant effect on intracellular Ca2+ concentration ([Ca2+]i) and did not alter [Ca2+]i elicited by CCh. Ca ionophore A23187 (5 microM)-induced amylase release in guinea pig acini was enhanced twofold by the addition of propionate. Cellular cAMP content was increased slightly by propionate, but did not alter dose dependently. The cAMP level with combinations of CCh and propionate was almost same as that with CCh alone and propionate alone. Staurosporine did not modify amylase secretion induced by a combination of CCh and propionate. These results suggest that propionate, in addition to a direct action on amylase release, potentiates CCh-induced amylase release in guinea pig and vole acini via a secretory pathway not associated with an increase in [Ca2+]i and cellular cAMP.  (+info)

The authors investigated the effects of postnatal manipulations of oxytocin (OT) on the subsequent tendency to form a partner preference in male prairie voles (Microtus ochrogaster). Neonatally, males received either an injection of OT, an oxytocin antagonist (OTA), 0.9% saline vehicle, or handling without injection. As adults, males were tested for partner preference
This study compared the effects of centrally administered oxytocin (OT) and arginine vasopressin (AVP) on partner preference formation and social contact in male and female prairie votes (Microtus ochrogaster). After 1 hr of cohabitation and pretreatment with either AVP or OT, both males and females exhibited increased social contact and significant preference for the familiar partner. After pretreatment with either an OT receptor antagonist (OTA) or an AVP (V1a) receptor antagonist (AVPA), neither OT nor AVP induced a partner preference.

Many female terrestrial mammals undergo postpartum estrus (PPE), a state of heightened sexual attractiveness to male conspecifics relative to females not in PPE (REF females). PPE and REF females of several species may use over-marks to maintain territories and attract and indicate interest in males as potential mates. In our first two experiments, we determined if the response of male meadow voles, Microtus pennsylvanicus, to the top- and bottom-scent donors of a same-sex over-mark was affected by the reproductive state of the scent donors. We found that after exposure to a same-sex over-mark in which the female scent donors were in the same reproductive state, males spent more time investigating the mark of the top-scent female. Males, however, spent more time investigating the mark of the PPE female to that of a female not in PPE, independent of the position of either females scent mark in the over-mark. The third and fourth experiments determined if the response of males to the female scent donor

Differential predation on certain classes of individuals within prey populations might make owls strong selective agents on their prey. We investigated selective predation of tawny owls (Strix aluco) on yellow-necked mice (Apodemus flavicollis, A.f.) and bank voles (Myodes glareolus, M.g.) for two years by comparing prey from owl nests with live-trapped individuals. The owls killed significantly more male M.g. (73%) than females, but not more than expected from traps (57%). For A.f., owls selected adults in favour of subadults, and for adults, individuals with longer femurs. Adult males of A.f. killed by owls had significantly heavier testes in relation their size than the trapped males. Prey selection did not correlate with size-adjusted body or spleen mass. Owl-killed A.f. had higher prevalences of the intestinal helminth Heligmosomoides sp. than trapped individuals, but hosted similar numbers of parasite species. Differential predation of tawny owls on yellow-necked mice and bank voles seems ...
All sections of watercourse with level ground or a gentle slope (,3% gradient) within the NNR were included in the survey. The banks of each watercourse were surveyed and signs of water vole activity were noted. Where access and water depth allowed, the search was conducted from the channel itself. Water vole signs separated by less than 200 m within one watercourse were considered to be within one colony, as adult males are known to have a home range of up to 200 m (Capreolus 2005; Sah 1998). Water vole habitat was assessed longitudinally as a series of contiguous survey sections. For the purposes of recording, habitat section breaks were inserted where the habitat type changed significantly. If habitat remained uniform section breaks were created approximately every 200 m. Each survey section was ranked in one of three categories: optimal (O), sub-optimal (SO) or unsuitable (US) water vole habitat ...
Two strains of Gram-positive cocci were isolated from viscera of common voles (Microtus arvalis Pallas) with generalized Brucella microti infection in the Czech Republic. Biochemical features and phylogenetic analysis based on 16S rRNA gene sequences showed that the strains are representatives of the genus Staphylococcus and assigned Staphylococcus muscae as the nearest relative. A detailed characterization done by ribotyping, rpoB and hsp60 gene sequencing, whole-cell protein analysis and rep-PCR using the (GTG)5 primer differentiated the two strains from all described staphylococci. DNA-DNA hybridization with the type strain of S. muscae demonstrated that the two strains should be considered as members of a novel species (26.8 % reassociation). The two analysed strains were found to be coagulase-negative, novobiocin-susceptible, oxidase-negative cultures, phenotypically close to one another, but showing differences in ribotype profiles. The major fatty acids were iso-C15 : 0, iso-C17 : 0, anteiso-C15
I have, in this thesis, studied the interactions between gray-sided voles (Clethrionomys rufocanus) and tundra vegetation, on islands in, and mainland sites close to the lake Iešjávri, in northern Norway. As isolated islands are virtually free of predation, I have been able to compare plant-herbivore interactions in the presence and absence of predators. I transplanted vegetation from an island with predators and voles, to predator-free islands with and with out voles. The results reveal the existence of a terrestrial trophic cascade as voles had a severe impact on the transplanted vegetation on the predator-free islands, but only minor effects on the mainland where predators are present. Moreover, this study shows that plant defence was only a successful strategy when predators were present. Voles reduced the abundance of all available plants during winter on the predator-free islands. The results imply that cascading effects of predation are most important for well-defended plants with ...
Much interest has centred recently on the role of adaptive trade-offs between the immune system and other components of life history in determining resistance and parasite intensities among hosts. Steroid hormones, particularly glucocorticoids and sex steroids, provide a plausible mechanism for mediating such trade-offs. A basic assumption behind the hypothesis, however, is that steroid activity will generally correlate with reduced resistance and thus greater parasite intensities. Here, we present some findings from a field study of bank voles (Clethrionomys glareolus ) in which we have looked at associations between parasite intensities, anatomical and morphometric measures relating to endocrine function and life history variation in three local populations inhabiting similar but mutually isolated woodland habitats. In general, sites with greater parasite intensities were those in which male C. glareolus had significantly larger adrenal glands, testes and seminal vesicles for their age and ...

Puumala hantavirus is present in bank voles (Myodes glareolus) and is believed to be spread mainly by contaminated excretions. In this study, we subcutaneously inoculated 10 bank voles with Puumala virus and sampled excretions until day 133 postinfection. Levels of shed viral RNA peaked within 11-28, 14-21, and 11-28 days postinfection for saliva, urine, and feces, respectively. The latest detection of viral RNA was 84, 44, and 44 days postinfection in saliva, urine, and feces, respectively. In contrast, blood of 5 of 6 animals contained viral RNA at day 133 postinfection, suggesting that bank voles secrete virus only during a limited time of the infection. Intranasal inoculations with bank vole saliva, urine, or feces were all infectious for virus-negative bank voles, indicating that these 3 transmission routes may occur in nature and that rodent saliva might play a role in transmission to humans ...

Grasslands are among the most imperiled of the North American ecosystems, with ≤ 1% of tallgrass prairie remaining. The State Acres for Wildlife Enhancement (SAFE) is a national conservation program that converts agricultural fields into grasslands with the primary focus on improving habitat for high priority wildlife species. Because small mammals can be important indicators of ecosystem function, I sampled small mammal communities to evaluate restoration efforts under the SAFE program in Illinois. I livetrapped small mammals during 3 summers (2009-2011) on plots that were recently seeded, seeded 1-4 years prior to sampling, or established references (>10 yrs old). Overall, the dominant species were the deer mouse (Peromyscus maniculatus), prairie vole (Microtus ochrogaster), and meadow vole (Microtus pennsylvanicus); which combined represented 92-97% of total captures each year. Typical restoration trajectories for small mammal communities included a shift over time from dominance by ...

Synaptic pruning within neurons in the brain during development allows for maintenance of proper neuronal connections and the elimination of aberrant ones. Rapid eye movement (REM) sleep is critical for pruning and maintaining new synapses formed during both development and learning. We hypothesize that disrupting REM sleep early in life will result in long lasting changes in synaptic density in cortical brain regions. The prefrontal cortex (PFC) is a late-maturing region that modulates higher order social and cognitive functions. Abnormally high dendritic spine density in the PFC is implicated in neurodevelopmental disorders such as autism spectrum disorder (ASD). Emerging research in our lab suggests that selectively suppressing REM sleep early in life in the socially monogamous prairie vole (Microtus ochrogaster) impairs social development and increases inhibitory interneurons in the PFC, consistent with ASD pathology. Using Golgi-Cox staining in adult prairie vole post-mortem tissue, we quantified

To get a deeper insight into the function of estrogen-related receptors (ERRs) and dissect underlying mechanism in Leydig cells, ERRs (type α, β and γ) were blocked or activated in testes of adult bank voles (Myodes glareolus) which show seasonal changes in the intratesticular sex hormones level. Both actively reproducing animals (long day conditions; LD) and those with regression of the reproductive system (short day conditions; SD) received intraperitoneal injections of selective ERRα antagonist 3-[4-(2,4-Bis-trifluoromethylbenzyloxy)-3-methoxyphenyl]-2-cyano-N-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)acrylamide (XCT 790) or selective ERRβ/ERRγ agonist N-(4-(Diethylaminobenzylidenyl)-N-(4-hydroxybenzoyl)-hydrazine (DY131) (50 μ/kg bw; six doses every other day ...

TY - JOUR. T1 - The effects of density-dependent dispersal on the spatiotemporal dynamics of cyclic populations. AU - Smith, Matthew J.. AU - Sherratt, Jonathan A.. AU - Lambin, Xavier. PY - 2008/9/21. Y1 - 2008/9/21. N2 - Density-dependent dispersal occurs throughout the animal kingdom, and has been shown to occur in some taxa whose populations exhibit multi-year population cycles. However, the importance of density-dependent dispersal for the spatiotemporal dynamics of cyclic populations is unknown. We investigated the potential effects of density-dependent dispersal on the properties of periodic travelling waves predicted by two coupled reaction-diffusion models: a commonly used predator-prey model, and a general model of cyclic trophic interactions. We compared the effects of varying the gradient of both positive and negative density-dependent dispersal rates, to varying the ratio of the (constant) dispersal rates of the two interacting populations. Our comparison focussed on the possible ...
The sibling vole is an accidentally introduced species in Svalbard and is the only small mammal species on the archipelago. They were first discovered in 1960 and misidentified as the common vole Microtus arvalis.
Not all of the experiences in nature and moments spent with animals can be labelled with name „expedition. I decided to post the one most interesting photo every month to describe a particular moment. The May will be represented by the close observation of the bank vole (Myodes glareolus) in the Beskydy mountains near Nový Hrozenkov. This young animal behaved very friendly and had no problem with photographing from a very small distance. What a nice encounter! ...
The water vole (Arvicola amphibius) in the forest-steppe of West Siberia is known to have wide fluctuations in abundance. These fluctuations are accompanied by changes in birth and death rates, sex-age structure of the population, and individual morphophysiological and behavioral characteristics of the animals. Survival of the animals depends on season, phase of population cycle, and sex. Based on the data of long-term captive breeding of water voles, the maximal lifespan of males was found to be 1188 days and that of females, 1108 days. There were no differences between the sexes in mean lifespan. The probability of living 2 years or longer was 0.21. Individuals who began breeding at an older age had a significantly longer lifespan and produced more offspring. The survival curves of the spring-born animals were steeper than of those summer/autumn-born. Maternal factors had differential effect on males and females with respect to lifespan. Male lifespan correlated negatively with maternal age, parity,
We were able to show that bank vole females gained long-term fitness benefits from multiple mating with different males. Offspring of polyandrous females performed significantly better at reproduction than those of monandrous females, caused mainly by sons of polyandrous females producing more offspring than those of monandrous females. Offspring body mass and survival were not affected by mating treatment. To our knowledge, this is the first experimental study on mammals measuring offspring reproductive performance as fitness component potentially affected by polyandry.. Recent studies have demonstrated an increase in female fitness due to polyandry that can be attributed to genetic effects (Neff & Pitcher 2005; Simmons 2005). Most of these studies, including two on mammals, have focused on early offspring survival as a component of fitness. For example, a field study on the brown antechinus Antechinus stuartii showed that polyandry significantly increased offspring survival until weaning ...

The best distribution models provided good predictions of the present-day Siberian ranges of the study species. Their LGM projections showed that areas with a suitable LGM climate for the three temperate species (Apodemus flavicollis, Apodemus sylvaticus and Microtus arvalis) were largely restricted to the traditionally recognized southern refuge areas, i.e. mainly in the Mediterranean region, but also southernmost France and southern parts of the Russian Plain. In contrast, suitable climatic conditions for the two boreal species (Clethrionomys glareous and Microtus agrestis) were predicted as far north as southern England and across southern parts of central and eastern Europe eastwards into the Russian Plain. For the two arctic species (Lemmus lemmus and Microtus oeconomus), suitable climate was predicted from the Atlantic coast eastward across central Europe and into Russia. Main conclusions ...
The crash phase of vole populations with cyclic dynamics regularly leads to vast areas of uninhabited habitats. Yet although the capacity for cyclic voles to re-colonize such empty space is likely to be large and predicted to have become evolved as a distinct life history trait, the processes of colonization and its effect on the spatio-temporal dynamics have been little studied. Here we report from an experiment with root voles (Microtus oeconomus) specifically targeted at quantifying the process of colonization of empty patches from distant source patches and its resultant effect on local vole deme size variation in a patchy landscape. Three experimental factors: habitat quality (1), predation risk (2) and inter-patch distance (3) were employed among 24 habitat patches in a 100x300 m experimental area. The first born cohort in the spring efficiently colonized almost all empty patches irrespective of the degree of patch isolation and predation risk, but dependent on habitat quality. Just after ...
Variation at 21 allozyme loci and 10 restriction enzymes within the mitochondrial DNA control region was assessed among 3 allopatric populations of montane vole (Microtus montanus) in the American Southwest. Among populations of M. montanus, the population from the White Mountains, Arizona, was most genetically divergent. Genetic and biogeographic evidence supported recognition of the White Mountains population as a distinct subspecies, M. m. arizonensis. Results also supported recognition of the Mogollon vole (Microtus mogollonensis) as distinct from the Mexican vole (Microtus mexicanus).
An early spring sample from a common vole population controlled by poisoning on the 22 March in a winter rape field was analysed from the point of view of its relative density and sexual activity. The relative population density was high (three different methods for density estimation have been used). The sexual condition of both males and females was determined, regarding the following aspects. In males, the gvI index (length of glandula vesicularis multiplied by the length of the testis) was decisive to assess sexual activity. The male was regarded as sexually active when the gvI exceeded 50 and the cauda epididymidis and ductus epididymidis were relatively large. In females the stage of sexual activity was determined by the presence or absence of corpora lutea, of the vaginal plug, by the presence and size of maculae cyaneae and the form of the uterus. The studied population was found to be already sexually active, some over win te red females started to reproduce at the end of January and at ...

I am not an adept when it comes to identifying skulls and bones that were festering in owl pellets, but I know the parts in Carma Jos pellet were from small rodents. The primary victim was probably the hapless beast hanging here, the Meadow Vole, Microtus pennsylvanicus. Do yourself a favor: never come back as a vole. Everyone wants to eat you, and the end will not be pretty. Very few voles, I suspect, die of old age. The animal in this photo was harvested by a Northern Shrike, which unceremoniously hung it in this autumn-olive bush. We saw almost the whole thing go down, and it was cool! The shrike, or butcherbird, came lumbering in toting the vole, disappeared into the shrubs, and as soon as the bird left we dashed in to inspect the kill. Later, the shrike, which is essentially a feathered Vlad the Impaler, would have returned and torn the cute little critter apart, gobbling down the chunks ...
The name vole is short for the archaic word volemouse, which may come from Norwegian vollmus, from the Old Norse völlr, field and Old Norse mūs, mouse. Voles are rodents, in the same family (Crecetidae) as lemmings, and like lemmings they sometimes have population explosions. The field vole, Arvicola agrestis, was so plentiful in Scotland, causing so much damage in 1890-1 that the Government appointed a Committee to examine the question. The committee wondered whether the destruction of predators by gamekeepers was responsible, but in true Darwinian fashion, the Scottish outbreak was dealt with by a rapid natural increase in the population of birds of prey.[1] A more recent vole explosion permitted snowy owls to colonise and breed in the Shetland Islands for a number of years. Voles range in color from gray to brown and in size from three to nine inches long. They have rounded bodies and blunt snouts, small ears and short tails without much hair. Their main food is grasses, but they also eat ...
Elucidating the colonization processes associated with Quaternary climatic cycles is important in order to understand the distribution of biodiversity and the evolutionary potential of temperate plant and animal species. In Europe, general evolutionary scenarios have been defined from genetic evidence. Recently, these scenarios have been challenged with genetic as well as fossil data. The origins of the modern distributions of most temperate plant and animal species could predate the Last Glacial Maximum. The glacial survival of such populations may have occurred in either southern (Mediterranean regions) and/or northern (Carpathians) refugia. Here, a phylogeographic analysis of a widespread European small mammal (Microtus arvalis) is conducted with a multidisciplinary approach. Genetic, fossil and ecological traits are used to assess the evolutionary history of this vole. Regardless of whether the European distribution of the five previously identified evolutionary lineages is corroborated, this
This thesis deals with the dynamics of tundra living voles with emphasis on the most common one, the grey-sided vole (Clethrionomys rufocanus). The tundra area chosen for the study was Finnmarksvidda, a vast flatland in northernmost Norway. All small mammal herbivores in the area showed dramatic fluctuations, and field experiment were conducted in order to elucidate these density fluctuations. The specific subjects addressed included: 1/ Temporal and spatial appearance of density fluctuations of voles and lemmings in the area, 2/ The generality of the density patterns observed, 3/ The impact of predation by vole predators during summertime, 4/ The impact of grey-sided vole grazing on food plants of different preference in a predator free environment, in the presence and absence of extra food, and 5/ The impact of food availability on density and demography of grey-sided voles in a predator free environment.. The results achieved showed that voles in the slope and lowland had cyclic density ...

1. Mathematical models for infectious diseases typically use contact rates (e.g. the number of other people a person encounters per day) as one of their main elements in predicting the outcomes of an epidemic. The aim of my project is to investigate the importance of spatial constraints and individual heterogeneity on the rate of contact of wildlife using field voles (Microtus agrestis) as a case study. By spatial constraints, I mean the importance that spatial distance plays in the rate of contact. Furthermore by individual heterogeneity, I mean the importance of characteristics such as mass and sex in determining the rate of contact.. We intuitively know that the further apart two individuals/voles are from each other, the harder it would be for a pathogen to spread. But how far is far? Incorporating these spatial constraints into the rate of contact models would help us investigate this. Studying characteristics such as mass and sex would help us investigate the features of dominant hubs in ...

The ovarian steroids, 17-beta estradiol (E2) and progesterone (P4), are critical for normal uterine function, establishment and maintenance of pregnancy, and mammary gland development. Furthermore, the local effects that are essential for normal ovarian physiology are dependent on the endocrine, paracrine, and autocrine actions of E2, P4, and androgens. In most mammals (including humans and mice), ovarian steroidogenesis occurs according to the two-cell/two-gonadotropin theory. This theory describes how granulosa and theca cells work together to make the ovarian steroids. Theca cells respond to LH signaling by increasing the expression of enzymes necessary for the conversion of cholesterol to androgens, such as androstenedione (A) and testosterone (T). Granulosa cells respond to FSH signaling by increasing the expression of enzymes necessary for the conversion of theca-derived androgens into estrogens (E2 and estrone ...

Dr Young has found that one difference between monogamous prairie voles and promiscuous montane voles is in the distribution of vasopressin and oxytocin receptors in the brain. His hypothesis is that if the receptors are not expressed in certain areas, then smell and sex will no longer coordinate to form social memory. Hence, when a montane vole mates, it does not form a lasting bond with its partner and is therefore unrestrained when encountering a different potential mate. (This hypothesis is strongly supported by a wealth of pharmacological and genetic data, which I wont go into-unless asked ...

With the onset of fall?s cool weather, animals are making plans to overwinter in your yard. Voles are one of the main rodents that love to hang around and feed. There are many species. Some will tunnel underground to feed on plant roots and bulbs. Others will stay near the surface to feed on shrub and tree bark and grass roots. Whatever the type, voles can wreak havoc on your plants. There is a new product that will bait and trap them to reduce their numbers while being safe for other animals. The Vole Control Bait Station contains a fruit-based poison bait that the voles love to eat. It can be set up as a ?tent? station among your plants to control aboveground voles, or as a ?mulch? station, buried under mulch to control belowground voles. The station is designed to attract only voles, and the poison bait is kept hidden and dry so children and other animals can?t reach it. Simply set up the station in an area where voles are active and check every few days to see if the bait has been taken or ...
The prairie vole is one of the few species in nature that is monogamous and that creates deep social bonds while mating. The basic mechanisms of voles and humans social learning are similar enough that the learning that occurs during voles pair bonding can model complex human social interactions. Young and his colleagues have used voles to show the importance for social interactions of hormones such as oxytocin, which has also been proposed as a treatment for autism spectrum disorders ...
Forest habitats after harvesting or wildfire disturbance are usually dominated by early successional vegetation for up to 5-10 years, as well as downed wood or coarse woody debris (CWD). Abundance of Microtus voles is often highest in these sites with sufficient plant cover being crucial for population increases. The role of CWD for voles is less clear. We tested the hypotheses (H) that (H1) abundance and reproduction of meadow vole (Microtus pennsylvanicus) and long-tailed vole (Microtus longicaudus) populations would be higher on sites with greater amounts of downed wood and that (H2) this relationship would be stronger on sites with sparse vegetation cover. There were two study areas: a dry Douglas-fir (Pseudotsuga menziesii)-lodgepole pine (Pinus contorta) forest and a high-elevation Engelmann spruce (Picea engelmannii)-subalpine fir (Abies lasiocarpa) forest in southern British Columbia, Canada. We monitored the responses of meadow voles and long-tailed voles to three levels of downed wood ...
The grey red-backed vole feeds on grasses and small herbs, the leaves and shoots of sub-shrubs and berries.[1] It prefers the bilberry (Vaccinium myrtillus) to the northern crowberry (Empetrum nigrum ssp. hermaphroditum) which contains unpalatable phenolic substances.[5] In tundra regions, this vole exhibits outbreaks when its numbers increase substantially. These occur in a four to five-year population cycle[1] the reasons for which are not fully understood but which may reflect changes in the abundance of certain specialised predators.[6] Lemmings have similar but more violent population explosions. These happen in the same years as vole outbreaks, but occur less frequently. This is partly because lemmings continue to breed during the winter months while populations of grey red-backed voles decline during the winter.[7] ...
Social monogamy is a mating strategy rarely employed by mammalian species. Laboratory studies in socially monogamous prairie voles Microtus ochrogaster demonstrate that oxytocin and vasopressin act within the mesolimbic dopamine pathway to facilitate pair-bond formation. Species differences in oxytocin receptor (OTR) and vasopressin 1a receptor (V1aR) distribution in this pathway are associated with species differences in mating strategy. Here, we characterize the neuroanatomical distribution of OTR and V1aR binding sites in naturally occurring populations of Taiwan voles Microtus kikuchii, which purportedly display social monogamy. Live trapping was conducted at two sites in 2009-2010 and receptor autoradiography for OTR and V1aR was performed on brains from 24 animals. OTR binding in two brain regions where OTR signaling regulates pair-bonding were directly compared with that of prairie voles. Our results show that like prairie voles, Taiwan voles exhibit OTR in the prefrontal cortex, insular ...
Drug addiction has devastating consequences on social behaviors and can lead to the impairment of social bonding. Accumulating evidence indicates that alterations in oxytocin (OT) and dopamine (DA) neurotransmission within brain reward circuitry may be involved. We investigated this possibility, as well as the therapeutic potential of OT for drug-induced social deficits, using the prairie vole (Microtus ochrogaster)-a socially monogamous rodent that forms enduring pair bonds between adult mates. We demonstrate that repeated exposure to the commonly abused psychostimulant amphetamine (AMPH) inhibits the formation of partner preferences (an index of pair bonding) in female prairie voles. AMPH exposure also altered OT and DA neurotransmission in regions that mediate partner preference formation: it decreased OT and DA D2 receptor immunoreactivity in the medial prefrontal cortex (mPFC) and nucleus accumbens (NAcc), respectively, and increased NAcc DA levels. Administration of OT directly into the ...

We have previously shown that monogamous and non-monogamous vole species have dramatically different distributions of CRF receptor type 1 (CRF1) and CRF receptor type 2 (CRF2) in the brain and that CRF1 and CRF2 receptor densities in the nucleus accumbens (NAcc) are correlated with social organization. Monogamous prairie and pine voles have significantly lower levels of CRF receptor type 1 (CRF1), and significantly higher levels of type 2 (CRF2) binding, in NAcc than non-monogamous meadow and montane voles. Here, we report that microinjections of CRF ...
SUMMARY The known range of the zoonotic fox tapeworm Echinococcus multilocularis has expanded since the 1990s, and today this parasite is recorded in higher abundances throughout large parts of Europe. This phenomenon is mostly attributed to the increasing European fox populations and their invasion of urban habitats. However, these factors alone are insufficient to explain the heterogeneous distribution of the parasite in Europe. Here, we analysed the spatial interrelationship of E. multilocularis with the known distribution of seven vole species in Ticino, southern Switzerland. Among 404 necropsied foxes (1990-2006) and 79 fox faecal samples (2010-2012), E. multilocularis was consistently found in the north of the investigated area. No expansion of this endemic focus was recorded during the 22 years of the study period. This stable endemic focus is coincident with the known distribution of the vole species Microtus arvalis but not, or only partly, with the distribution of the other ...
A Vero E6 cell culture isolate of Tula virus (TUL), a hantavirus first detected in European common voles (Microtus arvalis and M. rossiaemeridionalis) by RT-PCR was obtained after initial passaging of TUL-infected vole lung samples in laboratory-colonized M. arvalis. TUL was defined as a classical serotype by a cross-focus-reduction neutralization test (FRNT) and was also shown to be distinct from other hantaviruses by haemagglutination inhibition assay. The sequences of S, M and partial L genome segments of the isolate were determined: the S segment was 99·9% identical to the original rodent-derived sequence. Serological evidence for a previous TUL infection was obtained from the serum of a blood donor living near a TUL focus in Moravia, Czech Republic, showing at least a 16-fold higher FRNT titre to TUL as compared to Puumala or other hantaviruses.

Gammaherpesviruses are the archetypes of persistent viruses that have been identified in a range of animals from mice to man. They are host-range specific and establish persistent, productive infections of immunocompetent hosts. Thus, infected individuals simultaneously both elicit antiviral protective immune response and secrete infectious virions. The best studied gammaherpesviruses are Human herpesvirus 4 and Human herpesvirus 8. As these viruses have no well-established in vivo infection model, related animal gammaherpesviruses are an important source of information. We are studying Murid herpesvirus 4 (MuHV-4), a virus that has originally been isolated from bank voles (Myodes glareolus). Although MuHV-4 has not been isolated from house mice (Mus ...

The genetic diversity of Puumala hantavirus (PUUV) was studied in a local population of its natural host, the bank vole (Myodes glareolus). The trapping area (2.5x2.5 km) at Konnevesi, Central Finland, included 14 trapping sites, at least 500 m apart; altogether, 147 voles were captured during May and October 2005. Partial sequences of the S, M and L viral genome segments were recovered from 40 animals. Seven, 12 and 17 variants were detected for the S, M and L sequences, respectively; these represent new wild-type PUUV strains that belong to the Finnish genetic lineage. The genetic diversity of PUUV strains from Konnevesi was 0.2-4.9% for the S segment, 0.2-4.8% for the M segment and 0.2-9.7% for the L segment. Most nucleotide substitutions were synonymous and most deduced amino acid substitutions were conservative, probably due to strong stabilizing selection operating at the protein level. Based on both sequence markers and phylogenetic clustering, the S, M and L sequences could be assigned ...
Glucagon is conventionally regarded as a counterregulatory hormone for insulin and plays a critical anti-hypoglycemic role by maintaining glucose homeostasis in both animals and humans. To increase blood glucose, glucagon promotes hepatic glucose output by increasing glycogenolysis and gluconeogenesis and by decreasing glycogenesis and glycolysis in a concerted fashion via multiple mechanisms. Glucagon also stimulates hepatic mitochondrial beta-oxidation to supply energy for glucose production. Glucagon performs its main effect via activation of adenylate cyclase.

By creating artificial selection lines divergent for male T and measuring subsequent reproductive fitness of F1 full siblings, we demonstrated several important elements of intralocus sexual conflict in the small mammal M. glareolus. First, we show that inheritance patterns of paternal T reveal a negative correlation on the fitness of opposite-sex progeny (father-daughter, mother-son; table 1 and figure 1). Second, we show a selection line by sex interaction between reproductive fitness estimates in male and female bank voles (figure 2). Third, the fitness of full siblings is negatively correlated (figure 3). Accordingly, our study indicates that sexually antagonistic selection is probably acting on the steroid hormone T, which has importance implications for sexual selection.. Could the negative correlation in fitness between F1 full siblings be owing to mechanisms other than intralocus conflict? Differential non-genetic investment by mothers may produce such a result. However, bank vole ...
I am broadly interested in evolutionary and ecological research, but have a particular interest in understanding the ecological significance of adaptive genetic diversity. How does variation at adaptive genes influence individual fitness and adaptive potential and hence population viability? My research spans molecular ecology, conservation genetics, spatial dynamics and wildlife management. To date my work has focussed on investigating the processes underlying variation at MHC genes in the water vole (Arvicola terrestris), and using large scale approaches and genetic tools to explore community dynamics and dispersal, and thereby inform management strategies for the control of the invasive American mink (Neovison vison). My current work will combine stable isotope, genetic, and disease data, to characterise how natural selection acts upon American mink as they make the transition across the invasion gradient from farm to breeding in the wild ...
Mammalian coats are colored for a variety of reasons, the major selective pressures including camouflage, sexual selection, communication, and physiological processes such as temperature regulation. Camouflage is a powerful influence in a large number of mammals, as it helps to conceal individuals from predators or prey.[4] Aposematism, warning off possible predators, is the most likely explanation of the black-and-white pelage of many mammals which are able to defend themselves, such as in the foul-smelling skunk and the powerful and aggressive honey badger.[5] In arctic and subarctic mammals such as the arctic fox (Alopex lagopus), collared lemming (Dicrostonyx groenlandicus), stoat (Mustela erminea), and snowshoe hare (Lepus americanus), seasonal color change between brown in summer and white in winter is driven largely by camouflage.[6] Differences in female and male coat color may indicate nutrition and hormone levels, important in mate selection.[7] Some arboreal mammals, notably primates ...
Why do humans (and animals?) feel this emotion of love? What purpose does that serve? Literally, what is love? I read this one article in Science Magazine the other day that basically says that love is just a bunch of hormones and chemicals running through the brain. It said that oxytocin is released in the brain, which (for example) causes a human mother to take care of her baby instead of leaving it since it cant take care of itself. The oxytocin receptors happened to overlap with dopamine receptors in the part of the brain called the nucleus accumbens (generally regarded as one of the brains essential pleasure centers) (at least, this last statement is true in the case of the monogamous prairie voles). So I think that means that basically, every time a human being engages in an act of love, their brains reward them by feeling good, which encourages love. Is that right? If so, why is that so? I mean, why love when we could have instead just been able to survive independantly at birth? What ...

Gammaherpesviruses are the archetype of persistent viruses that have been identified in a series of animals ranging from mice to man. To date the study of transmission of these viruses in natural condition has been limited by the fact that no experimental transmission model exists. Establishment and characterization of a model of transmission are therefore critical points to evaluate strategies of interference with the epidemiological cycle of gammaherpesviruses. We are studying Murid herpesvirus 4 (MuHV-4) which has originally been isolated from naturally infected bank voles (Myodes glareolus). Although serological data indicate that closely related strains are present in wood mice (Apodemus sylvaticus) and domestic mice (Mus musculus), no experimental ...
So why are pair-bonding mammals more susceptible to substance abuse? Because the same neural circuitry that governs pair-bonding also governs susceptibility to substance abuse, and pair-bonders seem to have a more sensitive version of it than most mammals. When pair-bonding mammals are longing for a mate (whether or not they correctly analyze the roots of that longing), they are vulnerable to any neurochemical buzz that signals relief.. Scientists saw this recently when they compared the effects of amphetamine on two types of voles: pair-bonding prairie voles, and promiscuous montane voles. Dopamine rose significantly more in response to the drug use in the pair-bonding voles than in the voles who were not wired to seek long-term mates. The monogamous voles were inclined to find certain dopamine-based rewards more rewarding than their promiscuous vole cousins. In short, a lonely pair-bonder would have a greater risk of becoming an addict than would a mammal with no built-in urge to form a ...
This week I have decided to write about weasels. They are our smallest carnivore and widespread throughout Britain, but absent from most off-shore islands and Ireland. Being so widespread, it is perhaps unsurprising that they are found in a wide range of habitats. These range from urban areas, marshes, woodland, lowland pasture and moors. Prey for weasels are less numerous in areas such as high altitudes and very dense woodlands and as a result weasels are far less common in these areas. A weasels prey are small rodents such as voles and mice. If rodents are scarce then birds, eggs and even rabbits will be eaten. It is very common for dens made by prey species to be taken over.. In colder climates in Europe these dens are sometimes lined with the fur of lemming prey. During the breeding season it is usual for one litter of 4-6 young to be born, but this will often increase to two litters if field voles are abundant. ...

You would rather use natural alternatives that function like steroids, then you might want to take a closer look at Fadogia Agrestis.
Thats the Golden Guide to Mammals by Herbert S. Zim and Donald F. Hoffmeister, copyright 1955. It features 218 ANIMALS IN FULL COLOR, with maps of their distribution and short descriptions of their habitat and life histories. I remember reading that from cover to cover, practically memorizing it, and going on long walks out into the fields and forests around my home, looking for the elusive Boreal Red-Backed Vole or the dens of the Hoary Bat, or using it to try to identify the shredded carcasses of road kill.. Now with hindsight I realize its a rather awful little book, simultaneously too thin on information for each species to be really useful, and far too limited in breadth to be helpful in actually appreciating diversity, but I have to appreciate it for being an early provocateur, telling me that there was more to the life around me than people, my dog, and the lettuces and corn growing in the nearby fields. So thank you Drs Zim and Hoffmeister! I had to buy the rather ragged copy on sale ...

The present genetic analysis revealed that the mouthbrooding adults of X. rotundiventralis were most likely the genetic mothers and fathers of the young in their mouths. This result suggests that each female broods offspring that she has laid and each male receives the young that he has fertilized from his mate. This finding strongly suggests that the female-to-male shift of young takes place between mating partners. Therefore, the mating pairs most likely maintain the pair bonds at least until the female-to-male shift of young occurs. There are two possible explanations of why these pair bonds are not recognized by eye: one explanation is that the pairs maintain physical proximity, but mingle with other conspecific individuals in schools, and the other explanation is that the pairs do not maintain physical proximity most of the time. At present, there is no information regarding which explanation is more likely. One adult male (M38) was most likely the genetic father of the two young brooded by ...

The Late Pleistocene global extinction of many terrestrial mammal species has been a subject of intensive scientific study for over a century, yet the relative contributions of environmental changes and the global expansion of humans remain unresolved. A defining component of these extinctions is a bias toward large species, with the majority of small-mammal taxa apparently surviving into the present. Here, we investigate the population-level history of a key tundra-specialist small mammal, the collared lemming (Dicrostonyx torquatus), to explore whether events during the Late Pleistocene had a discernible effect beyond the large mammal fauna. Using ancient DNA techniques to sample across three sites in North-West Europe, we observe a dramatic reduction in genetic diversity in this species over the last 50,000 y. We further identify a series of extinction-recolonization events, indicating a previously unrecognized instability in Late Pleistocene small-mammal populations, which we link with ...

Every so often I have experiences in the ED where I step back and say to myself, Did that really just happen?. A quick example is when a patient asked me to test his blood for the level of crack in it. He wanted a precise number so that he could sue his drug dealer. Yup. Thats real. He thought his illegal drugs were not pure enough, so his plan was to take his drug dealer to court.. I told you that short story so I can tell you this one.. Working the night shift at our standalone ED means six busy hours followed by a gradual slowing into the night. Few people arrive after midnight, and the place dies after two in the morning.. I was sitting at my desk watching cat videos on YouTube. The entire building went black. Four seconds later, the power returned and the sounds of multiple computers resetting peppered the previously silent background.. What just happened? I asked the two nurses sitting a short distance away.. Generator check. Once a month it resets to make sure its working ...

Notice the sequence when the newborn (Inti, a 2 months old male) climbs onto the back of another female (Santi): he is first sitting on his mothers back and looks into the face of Santi before climbing on her back. Although he is still very young and clumsy, he is willing to leave his mother for another individual. This might seem surprising, but Santi is a childless female who spends a lot of time sitting next to Intis mother, Sylvie, and engaging Inti in various interactions (lipsmacking, grooming, etc). Worth pointing out is the fact that Santi and Sylvie are sisters.. Hrdys hypothesis goes further as she proposes that, in humans, alloparental care is the evolutionary precursor of mind reading capacities. This more controversial hypothesis could gain further support if cooperative breeding species of monkeys showed more developed capacities for mind reading capacities than non-human apes. To my knowledge, mind reading capacities in monkeys have not been thoroughly tested, maybe because ...

Rainbow Ear Studs .925 Sterling Silver - This is an awesome .925 sterling silver Circle Rainbow stud earrings. Show off your pride, or show how colorful you can be with these pair of ear studs. Fits regular ear piercing. Studs are sold in pairs. The size of the stud design is about 4-5 mm. Entire piece is nickel free.
An electronic stud finder will locate studs quickly and accurately. But if you dont have one, there are other methods you can use. Look on the floor for keel marks that were used to locate the studs before drywall installation. Electrical-outlet boxes are nailed into studs. Tap gently on the wall and listen for a duller sound when you tap over a stud. Or drive nails behind the cabinet to locate a stud. When one stud is found, other studs should be 16 in. or 24 in. from it. Once the studs are found, mark their locations inside the cabinets on the mounting rail. Predrill screw holes in the cabi-net mounting rail, set the cabinet in place, and drive a screw into each stud. If the screw misses the stud, check again for its location until you get it right. And feel free to use a few extra screws in wall cabinets. Just make sure they go into studs..
