How the clear-sky angle of polarization pattern continues underneath clouds: full-sky measurements and implications for animal orientation. (1/1226)

One of the biologically most important parameters of the cloudy sky is the proportion P of the celestial polarization pattern available for use in animal navigation. We evaluated this parameter by measuring the polarization patterns of clear and cloudy skies using 180 degrees (full-sky) imaging polarimetry in the red (650 nm), green (550 nm) and blue (450 nm) ranges of the spectrum under clear and partly cloudy conditions. The resulting data were compared with the corresponding celestial polarization patterns calculated using the single-scattering Rayleigh model. We show convincingly that the pattern of the angle of polarization (e-vectors) in a clear sky continues underneath clouds if regions of the clouds and parts of the airspace between the clouds and the earth surface (being shady at the position of the observer) are directly lit by the sun. The scattering and polarization of direct sunlight on the cloud particles and in the air columns underneath the clouds result in the same e-vector pattern as that present in clear sky. This phenomenon can be exploited for animal navigation if the degree of polarization is higher than the perceptual threshold of the visual system, because the angle rather than the degree of polarization is the most important optical cue used in the polarization compass. Hence, the clouds reduce the extent of sky polarization pattern that is useful for animal orientation much less than has hitherto been assumed. We further demonstrate quantitatively that the shorter the wavelength, the greater the proportion of celestial polarization that can be used by animals under cloudy-sky conditions. As has already been suggested by others, this phenomenon may solve the ultraviolet paradox of polarization vision in insects such as hymenopterans and dipterans. The present study extends previous findings by using the technique of 180 degrees imaging polarimetry to measure and analyse celestial polarization patterns.  (+info)

Speeds and wingbeat frequencies of migrating birds compared with calculated benchmarks. (2/1226)

Sixteen species of birds passing Falsterbo in southwest Sweden during the autumn migration season were observed using short-range optical methods. Air speeds and wingbeat frequencies were measured, reduced to sea level, and compared with benchmark values computed by Flight.bas, a published flight performance program based on flight mechanics. The benchmark for air speed was the calculated sea-level value of the minimum power speed (V(mp)). The mean speeds of three raptor species that flew by flap-gliding were below V(mp), apparently because the flap-glide cycle involved slowing down below V(mp) when gliding and accelerating back up to V(mp) when flapping. The mean speeds of 11 species that flew by continuous flapping were between 0.82V(mp) and 1.27V(mp). Two passerine species that flew by bounding had mean speeds of 1.70V(mp) and 1.96V(mp), but these high mean speeds reflected their ability to fly faster against head winds. These results do not support predictions from optimal migration theory, which suggest that migrating birds 'should' fly faster, relative to V(mp). However, observations were restricted for technical reasons to birds flying below 200 m and may not represent birds that were seriously committed to long-distance migration. The benchmark wingbeat frequency (f(ref)) was derived from dimensional reasoning, not from statistical analysis of observations. Observed wingbeat frequencies ranged from 0.81f(ref) to 1.05f(ref), except in the two bounding species, whose wingbeat frequencies appeared anomalously high. However, the mechanics of bounding with a power fraction q imply that gravity during the flapping phase is increased by a factor 1/q, and when the value of gravity was so adjusted in the expression for f(ref), the wingbeat frequencies of the two bounding species were predicted correctly as a function of the power fraction. In small birds with more muscle power than is required to fly at speeds near V(mp), bounding is an effective method of adjusting the specific work in the muscle fibres, allowing conversion efficiency to be maximised over a wide range of speeds.  (+info)

Light-dependent magnetoreception in birds: the behaviour of European robins, Erithacus rubecula, under monochromatic light of various wavelengths and intensities. (3/1226)

To investigate how magnetoreception is affected by the wavelength and intensity of light, we tested European robins, Erithacus rubecula, under monochromatic lights of various wavelengths at two intensities using oriented behaviour as an indicator of whether the birds could derive directional information from the geomagnetic field. At a quantal flux of 7 x 10(15) quanta s(-1) m(-2), the birds were well oriented in their migratory direction east of North under 424 nm blue, 510 nm turquoise and 565 nm green light, whereas they were disoriented under 590 nm yellow light. Increasing the intensity of light at the same wavelengths more than sixfold to 43 x 10(15) quanta s(-1) m(-2) resulted in a change in behaviour: under bright blue and green light, the birds now showed a preference for the East-West axis, with the majority of headings at the western end; under bright turquoise light, they oriented unimodally towards a direction slightly west of North. Under bright yellow light, the birds continued to be disoriented. These findings suggest a rather complex relationship between the receptors involved in magnetoreception. Magnetoreception appears to follow rules that are different from those of vision, suggesting that light-dependent magnetoreception may involve receptors and neuronal pathways of its own.  (+info)

Effects of duration and time of food availability on photoperiodic responses in the migratory male blackheaded bunting (Emberiza melanocephala). (4/1226)

The effects of the duration and time of food availability on stimulation of the photoperiodic responses (fattening and gain in body mass, and growth and development of testes) were investigated in the migratory blackheaded bunting (Emberiza melanocephala). Two experiments were performed. Experiment I examined the effects of a reduction in the duration of food supply in buntings that were subjected to long day lengths (16h:8h L:D) and received food ad libitum (group I) or for restricted durations, coinciding with the end of the lights-on period, of 8h (group II) and 4h (group III). Buntings of group I gained in body mass, whereas there was a mixed response in group II (half the birds gained and half lost body mass), and all birds of group III lost body mass. There was no effect on testis growth in groups I and II, but testes grew more slowly in group III. Experiment 2 investigated the effects of both the duration and the time of food availability. Of five groups of birds, group I was exposed to an 8h:16h L:D photoperiod, and groups II-V were exposed to 16h:8h L:D. Whereas birds of groups I and II received food ad libitum, those of groups III-V were fed only for 5 h, at zt 0-5 (group III), zt 5.5-10.5 (group IV) or zt 11-16 (group V), where zt = zeitgeber time and zt 0 refers to the beginning of the lights-on period. Apart from duration, the timing of food availability also had an effect on photoperiodic stimulation under the 16h:8h L:D photoperiod. Birds that were fed ad libitum fattened and gained in body mass, whereas among restricted feeding groups, only birds in the group fed during the first 5 h (zt 0-5, group III) showed a significant increase in body mass (albeit considerably lower than in the ad libitum group). Birds fed during the middle 5h (zt 5.5-10.5, group IV) showed an intermediate response, and those fed during the last 5h (zt 11-16, group V) lost body mass. Testicular growth was suppressed in birds that were fed for 5 h in the evening, but not in those fed for the same period in the morning or in the middle of the long day. Taken together, these results show that the duration of food supply and/or the time of day at which food is available affect photoperiodic stimulation of fattening and gain in body mass as well as the growth and development of gonads in the blackheaded bunting.  (+info)

Complex bird clocks. (5/1226)

The circadian pacemaking system of birds comprises three major components: (i) the pineal gland, which rhythmically synthesizes and secretes melatonin; (ii) a hypothalamic region, possibly equivalent to the mammalian suprachiasmatic nuclei; and (iii) the retinae of the eyes. These components jointly interact, stabilize and amplify each other to produce a highly self-sustained circadian output. Their relative contribution to overt rhythmicity appears to differ between species and the system may change its properties even within an individual depending, for example, on its state in the annual cycle or its photic environment. Changes in pacemaker properties are partly mediated by changes in certain features of the pineal melatonin rhythm. It is proposed that this variability is functionally important, for instance, for enabling high-Arctic birds to retain synchronized circadian rhythms during the low-amplitude zeitgeber conditions in midsummer or for allowing birds to adjust quickly their circadian system to changing environmental conditions during migratory seasons. The pineal melatonin rhythm, apart from being involved in generating the avian pacemaking oscillation, is also capable of retaining day length information after isolation from the animal. Hence, it appears to participate in photoperiodic after-effects. Our results suggest that complex circadian clocks have evolved to help birds cope with complex environments.  (+info)

Juvenile hormone regulation of longevity in the migratory monarch butterfly. (6/1226)

Monarch butterflies (Danaus plexippus) of eastern North America are well known for their long-range migration to overwintering roosts in south-central Mexico. An essential feature of this migration involves the exceptional longevity of the migrant adults; individuals persist from August/September to March while their summer counterparts are likely to live less than two months as adults. Migrant adults persist during a state of reproductive diapause in which both male and female reproductive development is arrested as a consequence of suppressed synthesis of juvenile hormone. Here, we describe survival in monarch butterflies as a function of the migrant syndrome. We show that migrant adults are longer lived than summer adults when each are maintained under standard laboratory conditions, that the longevity of migrant adults is curtailed by treatment with juvenile hormone and that the longevity of summer adults is increased by 100% when juvenile hormone synthesis is prevented by surgical removal of its source, the corpora allatum. Thus, monarch butterfly persistence through a long winter season is ensured in part by reduced ageing that is under endocrine regulation, as well as by the unique environmental properties of their winter roost sites. Phenotypic plasticity for ageing is an integral component of the monarch butterflies' migration-diapause syndrome.  (+info)

Deriving dispersal distances from genetic data. (7/1226)

Dispersal is one of the most important factors determining the genetic structure of a population, but good data on dispersal distances are rare because it is difficult to observe a large sample of dispersal events. However, genetic data contain unbiased information about the average dispersal distances in species with a strong sex bias in their dispersal rates. By plotting the genetic similarity between members of the philopatric sex against some measure of the distance between them, the resulting regression line can be used for estimating how far dispersing individuals of the opposite sex have moved before settling. Dispersers showing low genetic similarity to members of the opposite sex will on average have originated from further away. Applying this method to a microsatellite dataset from lions (Panthera leo) shows that their average dispersal distance is 1.3 home ranges with a 95% confidence interval of 0.4-3.0 home ranges. These results are consistent with direct observations of dispersal from our study population and others. In this case, direct observations of dispersal distance were not detectably biased by a failure to detect long-range dispersal, which is thought to be a common problem in the estimation of dispersal distance.  (+info)

Unexpected coherence and conservation. (8/1226)

The effects of migration in a network of patch populations, or metapopulation, are extremely important for predicting the possibility of extinctions both at a local and a global scale. Migration between patches synchronizes local populations and bestows upon them identical dynamics (coherent or synchronous oscillations), a feature that is understood to enhance the risk of global extinctions. This is one of the central theoretical arguments in the literature associated with conservation ecology. Here, rather than restricting ourselves to the study of coherent oscillations, we examine other types of synchronization phenomena that we consider to be equally important. Intermittent and out-of-phase synchronization are but two examples that force us to reinterpret some classical results of the metapopulation theory. In addition, we discuss how asynchronous processes (for example, random timing of dispersal) can paradoxically generate metapopulation synchronization, another non-intuitive result that cannot easily be explained by the standard theory.  (+info)

Pathogen exposure has been suggested as one of the factors shaping the myriad of migration strategies observed in nature. Two hypotheses relate migration strategies to pathogen infection: the avoiding the tropics hypothesis predicts that pathogen prevalence and transmission increase with decreasing non-breeding (wintering) latitude, while the "habitat selection hypothesis" predicts lower pathogen prevalence in marine than in freshwater habitats. We tested these scarcely investigated hypotheses by screening wintering and resident wading shorebirds (Charadriiformes) for avian malaria blood parasites (Plasmodium and Haemoproteus spp.) along a latitudinal gradient in Australia. We sequenced infections to determine if wintering migrants share malaria parasites with local shorebird residents, and we combined prevalence results with published data in a global comparative analysis. Avian malaria prevalence in Australian waders was 3.56% and some parasite lineages were shared between wintering migrants ...

Our results indicate that arrival timing on the breeding grounds, driven by conditions that experienced thousands of kilometres away on tropical wintering grounds, may influence the rates of polygyny and EP paternity in American redstarts, suggesting that non-breeding season events may carry over to influence the process of sexual selection. Specifically, we demonstrate that not only does winter territory quality influence apparent success through arrival timing (wherein variation in apparent success is driven largely by predation; Norris et al. 2004), but also carry-over effects from winter may influence behavioural processes such as female mate choice and male-male competition. Males overwintering in high-quality habitats arrive earlier on the breeding grounds than males overwintering in low-quality habitats (inferred by stable-carbon isotope analysis). In turn, early arriving males sire a higher proportion of their own offspring, sire EPO in the nests of late-arriving males, are more likely ...
The American redstart is a smallish warbler. It measures 11 to 14 cm (4.3 to 5.5 in) in total length and has a wingspan of 16 to 23 cm (6.3 to 9.1 in). Its length is boosted by a relatively long tail and it is one of the lightest birds in its family.[5] Weight is considerably less in winter than in summer. Males weigh an average of 8.6 g (0.30 oz) in summer but drop to 7.2 g (0.25 oz) in winter, while females drop even more from an average of 8.7 g (0.31 oz) to an average of 6.9 g (0.24 oz).[6][7] Among standard measurements, the wing chord is 5.5 to 6.9 cm (2.2 to 2.7 in), the tail is 4.9 to 5.8 cm (1.9 to 2.3 in), the bill is 0.7 to 0.9 cm (0.28 to 0.35 in) and the tarsus is 1.5 to 1.9 cm (0.59 to 0.75 in).[8] The breeding males are unmistakable, jet black above apart from large orange-red patches on their wings and tails. Their breast sides are also orange, with the rest of their underparts colored white. In their other plumages, American redstarts display green in their upperparts, along ...
Physiological challenges during part of the annual cycle (e.g. spring migration) can carry over and affect performance at subsequent phases (e.g. reproduction; Ebbinge and Spaans, 1995; Bauchinger et al., 2009; Legagneux et al., 2012), although the mechanisms that produce these carry-over effects are only rarely understood (Harrison et al., 2011). A particularly interesting but understudied potential mechanism for carry-over effects impacting reproductive performance concerns the antioxidant system and its ability to quench pro-oxidants. Generally, antioxidants provided to embryos are considered beneficial (Saino et al., 2003; McGraw et al., 2005; Berthouly et al., 2007, 2008; Marri and Richner, 2014; Jacob et al., 2015); however, if antioxidant supply is limited and requirements prior to reproduction are relatively high, then a females allocation of antioxidants to reproduction could be restricted and thus produce an important carry-over effect.. Birds rely on suites of antioxidant compounds, ...
The decline of long distance migratory songbirds has been linked to an increasing mismatch between spring arrival date and timing of food availability caused by climate change. It is unclear to what extent individuals can adjust migration timing or en route rate in response to annual variation in temperature at breeding sites. We tracked the ca. 7300 km spring migration of 52 purple martins Progne subis from the Amazon basin to two breeding sites in eastern North America. Spring 2012 was the warmest on record in eastern North America, but contrary to predictions, this did not result in earlier departure, faster migration, or earlier arrival at breeding areas compared with earlier years. Temperatures and rainfall in the Amazon basin at the time of departure were not higher in 2012, and conditions along migration routes did not give consistent signals of a warmer spring at the breeding site. Once in North America, individuals likely had limited opportunity to speed up their migration because this final
A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters (350 a , 350 b) is disclosed. Embodiments of the novel system and method enable the geolocation system to determine if signals being received by the geolocation system arrive directly from a target mobile appliance or if the signals are passing through a repeater (350 a , 350 b) and therefore are subject to a known time delay. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.
Migratory routes often include staging sites where migrants can rest and feed, and the loss of such sites can cause severe bottleneck effects on migratory populations [14,31,32]. That is, sudden declines in population flow can be triggered by small amounts of overall habitat loss owing to migratory connectivity [11,14,33]. By developing a method to estimate the amount of population flow travelling through a migratory route subject to habitat loss, we have shown that these effects can be very large across an assemblage of declining long-distance migrants. Importantly from a conservation perspective, the flyway-wide consequences of habitat loss through SLR differ dramatically among the taxa we studied, even though they all use the same geographical region. This is because of variation in the specific patterns of connectivity among sites as well as the absolute extent of habitat loss at the sites used by each taxon. This variation demonstrates that understanding the pattern of migratory ...
1. The seasonal migration of birds is divided into alternating phases of stopover and flight. The fuel deposition rate at stopover sites is the crucial factor determining overall speed of migration and its success. Therefore, field data about the variation in fuel deposition rates at different levels (among sites, seasons, days, individuals) are essential to explain the observed behavioural reactions to environmental variability and migration strategies. 2. Fuel deposition rates of four species of passerine migrant birds captured at 14 stopover sites from northern Europe to sub-Saharan Africa during autumn and spring were analysed. Plasma concentrations of triglycerides and β-hydroxy-butyrate were used to estimate relative fuel deposition rates (named fattening index). 3. The largest variation in fattening indices was between sites which was only weakly explained by geographical position relative to ecological barriers and did not differ between spring and autumn. Therefore it is expected that ...
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat, or weather. Sometimes, journeys are not termed "true migration" because they are irregular (nomadism, invasions, irruptions) or in only one direction (dispersal, movement of young away from natal area). Migration is marked by its annual seasonality.[9] Non-migratory birds are said to be resident or sedentary. Approximately 1800 of the worlds 10,000 bird species are long-distance migrants.[10][11]. Many bird populations migrate long distances along a flyway. The most common pattern involves flying north in the spring to breed in the temperate or Arctic summer and returning in the autumn to wintering grounds in warmer regions to the south. Of course, in the southern hemisphere the directions are reversed, but there is less land area in the far south to support long-distance migration.[12]. The primary ...
It uses the dreamy Earth wind map for inspiration. But rather than using temperature, wind, and sea level pressure data, Dan Majka, a web developer at The Nature Conservancy, used data from two studies to show all the feasible paths that mammals, birds, and amphibians can use to find their way to a more suitable climate as their habitat becomes too hot.. The map doesnt show specific species (youre not going to be able to find the grizzly bear path, for example), but rather shows the general patterns scientists expect animals to follow as the world warms.. The visualization is stunning, but also hopeful. It shows that despite the challenges of climate change and increased urbanization, there are still pathways for the natural world to deal with those threats.. ...

Researchers have isolated what are essentially tiny compass needles in the noses of rainbow trout that may explain these and many other animals incredible ability to navigate across vast distances.
The Road Ecology Center of the John Muir Institute of the Environment at the University of California, Davis performed an assessment of the impacts of roads on animal population viability. In their assessment they determined that roads and structures fragment animal populations. This reduces the numbers of animals found in an area and reduces the quality of the local environment. If their numbers and health are reduced because of infrastructure development their ability to migrate will also be negatively impacted since not all animals that perform a migration survive, the numbers of mature animals could be reduced. Roads, especially roads with a large amount of traffic can be very dangerous for migrating animals that could get hit by a vehicle. ...
Traditionally, bird migration has been treated separately relative to other movements within an individuals life history (1-2). Although long-distance migration operates on different scales and produces different patterns than those of other movement types in a birds life cycle, there are also many similarities (cf. ref. 3). As in other biotic movements, migration involves the assessment of internal state of the organism, external factors, and past behavior to make decisions about motion and navigation (4).. One significant challenge of migration research is measuring the extent to which migratory routes and schedules of individual migrants are influenced by external factors, including wind direction and speed (5-6), food availability and habitat (2), and the behavior of other migrants (1, 7). One important axis of variation among migratory birds is the extent to which environmental factors act as facilitators of, as opposed to barriers to, movement. Determining the effects of environmental ...
The Convention on Migratory Species, also known as the Bonn Convention, aims to conserve terrestrial, aquatic and avian migratory species throughout their range.
Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access to newly emerged, high quality forage along the green up gradient with increasing altitude; termed the forage maturation hypothesis. Any other limiting factor spatially correlated with this gradient may provide extra benefits or costs to migration, without necessarily being the cause of it. A common ectoparasite on cervids in Europe is the sheep tick (Ixodes ricinus), but it has not been tested whether migration may lead to the spatial separation from these parasites and thus potentially provide an additional benefit to migration. Further, if there is questing of ticks in winter ranges in May before spring migration, deer migration may also play a role for the distribution of ticks. We quantified the abundance of questing sheep tick within winter and summer home ranges of migratory (n
Migratory animals are often blamed for the global spread of diseases, but new Deakin University research has shown their role may be less significant than previously thought.. With the rate of zoonotic diseases - pathogens that jump from animal hosts to humans - on the rise, migratory animals have been under increasing scrutiny and suspicion of aiding the spread of bird flu, Lyme disease, and even Ebola.. However, despite the fact that billions of animals fly, swim and walk around the globe every year on their seasonal migrations, researchers from Deakin Universitys Centre for Integrative Ecology (CIE) say there is surprisingly little direct evidence that migratory animals are frequently spreading pathogens long distances.. "In humans, travelling increases our risk of getting ill because we come into contact with many new microbes that our immune system has never encountered before," said researcher and PhD candidate Alice Risely.. "We wanted to work out if migrant animals are also more ...

Most behavioral patterns relate in some way to daily, monthly, or seasonal environmental cycles. These videos depict animal migrations in relation to seasonal cycles, including cycles of growth and reproduction in other organisms. As you watch the videos, think about these questions and record your responses: 1. What environmental factors influence the behaviors of the animals in the videos at different stages of their migrations? 2. Why do you think the animals rely on those particular factors and not others? 3. How do these animals know the way the first time they travel their migration route? 4. How does the timing of migration affect an animals ability to survive and/or reproduce? ...
Abstract: Man/hardware-in-the-loop laboratory simulation is the most cost-effective methodology for evolving/maturing advanced receiver geolocation technologies because the battlefield can be brought to the laboratory through multi-spectral synthetic battlespace simulation. Current laboratory laboratory RF threat environment simulators do not provide the required fidelity to accurately simulate the parameters needed to develop ultra-precise direction finding and geolocation capabilities. DRA proposes to solve this challenging technology limitation by developing an Advanced RF Geolocation Simulation Testbed (ARGST) for rapid prototyping of advanced RF receiver processor geolocation. The ARGST flexible architecture will enable the development of advanced geolocation technologies for single and multiple aircraft within a controlled laboratory environment enabling repeatable test and step-by-step evaluation/debugging capabilities. ARGST will provide simulator technology to develop advanced ...

Osmond et al. 2013 looked at female carotenoid (yellowish) ornamentation in redstarts, restricting their study to nesting season in Ontario, and to just the bright (yellow) tail and flank ornamental patterns, and not the wing patches. Older females had brighter yellow tail feathers (but not flank) than yearling females. A model with both flank and tail brightness predicted 41% of the variation in yearling female fledging success, brighter females fledging fewer offspring, contrary to prediction. Pairing date, first egg date, and number of young fledged did not differ between yearling and older female age classes. Females with brighter tails fledged fewer young, but just in yearlings, whereas the number of visits older females made to nests declined with tail brightness. Older males made fewer visits to the nests of brighter colored older female mates, and spent less time at the nests based on females color brightness, although this relationship was not quite statistically significant. Females ...
The gray whale has the longest annual migration distance of any mammal. Gray whales leave Baja, California, and western Mexico in the spring, migrating to the Bering and Chukchi seas for the summer months. Tracking a sample of 50 whales for a year provided a mean migration distance of 11,064 miles with a standard deviation of 860 miles. Construct a 90% confidence interval for the variance for the migrating whales. Assume that the population of migration distances is Normally distributed ...

Like many other migratory birds, the black-throated blue warbler (Dendroica caerulescens) shows pronounced differences in migratory behaviour and other traits between populations: birds in the southern part of the breeding range have darker plumage and migrate to the eastern Caribbean during the winter, whereas those in the north have lighter plumage and migrate to the western Caribbean. We examined the phylogeography of this species, using samples collected from northern and southern populations, to determine whether differentiation between these populations dates to the Pleistocene or earlier, or whether differences in plumage and migratory behaviour have arisen more recently. We analysed variation at 369 bp of the mitochondrial control region domain I and also at seven nuclear microsatellites. Analyses revealed considerable genetic variation, but the vast majority of this variation was found within rather than between populations, and there was little differentiation between northern and ...
The behaviour of an Australian day migrant, the yellow-faced honeyeater Lichenostomus chrysops, was studied in order to assess the role of the sun in migratory orientation. During autumn migration, all tests took place under a sunny sky; birds were tested while living in the natural photoperiod (control) and with their internal clock shifted 4 h fast and 4 h slow. In spring, all birds were shifted 3 h fast; tests in overcast conditions, with the birds relying on their magnetic compass, served as controls. In control tests in both seasons, the birds preferred directions corresponding to those observed in the wild. When tested under sunny conditions with their internal clock shifted, the birds changed their directional tendencies. However, their preferred directions were different from those expected if a time-compensating sun compass was being used. After about 6 days, the shifted birds directions were no longer different from the control direction. This behaviour argues against a major role of ...

The Yellow Sea region is of high global importance for waterbird populations, but recent systematic bird count data enabling identification of the most important sites are relatively sparse for some areas. Surveys of waterbirds at three sites on the coast of southern Jiangsu Province, China, in 2014 and 2015 produced peak counts of international importance for 24 species, including seven globally threatened and six Near Threatened species. The area is of particular global importance for the Critically Endangered Spoon-billed Sandpiper Calidris pygmaea (peak count across all three study sites: 62 in spring [2015] and 225 in autumn [2014] and Endangered Spotted Greenshank Tringa guttifer (peak count across all three study sites: 210 in spring [2014] and 1,110 in autumn [2015]). The southern Jiangsu coast is therefore currently the most important migratory stopover area in the world, in both spring and autumn, for both species. Several serious and acute threats to waterbirds were recorded at ...

Sylvia also worked closely with the Gay Liberation Front and the Gay Activists Alliance (the latter her feeling was not radical enough). Sylvias life experiences hustling on the streets at age ten, stirred within her during these revolutionary days of gay liberation the idea of creating a refuge for underage street queens. Even though Sylvia was only nineteen at this time, she realized the hardships endured by the younger street youths hustling on the streets, finding shelter, food and safety and in the end many were dead after several years of being on the street due to drugs or violence against their queerness. Sylvia had a strong desire to setup a place where these young street youth could find comradeship, safety, family, community and importantly learn skills to move on to a better kind of life. And so S.T.A.R. was officially formed following Sylvias engagement with the NYU Weinstein Hall occupation in 1970. STARs first home was in the back of a trailer truck, or at least until one day ...
The cat in question was Holly, a 4-year-old tortoiseshell who disappeared when her owners took her to an RV rally in Daytona Beach, Fla. Apparently some people have been known to become confused and claim a stray cat as long-lost Fluffy or Max. Other animals directional prowess has been studied, and sundry explanations have been offered. [...] just as we really dont know how long-distance migratory birds find their way back to the same spot year after year, we dont know much about cats. Alas, the presence of the experimenter affected the experiment; the cat became uneasy as I quietly followed him around and fled to a small, blackberry-choked space behind the neighbors garage. There was some thought that she might have hitchhiked a ride, although how would she know which truck to choose? [...] nobody is willing to do a mass study, in which a statistically significant number of cats are taken from their homes and deposited 50 miles away to see which ones would make it home. People are also
Background/Question/Methods. Climate warming, physical barriers such as dams and fences, and anthropogenic food subsidies have caused many historically migratory populations to travel shorter distances or form sedentary populations. This behavioral shift could alter interactions with parasites, in part by increasing the duration of exposure to infectious agents that accumulate in the hosts environment or by increasing local host densities. Here we present a modeling framework for understanding how migratory host-pathogen dynamics are influenced by two potential movement responses to global change: (i) shortened migrations and (ii) abandonment of migration by a fraction of the population (partial migration). Results/Conclusions. We find that shortened migrations that lead to increases in host population size and migratory survival of infected individuals can result in extremely high infection prevalence. We also find that the onset of sedentary behavior can allow invasion of more virulent ...
As an environmental treaty under the aegis of the United Nations Environment Programme, CMS provides a global platform for the conservation and sustainable use of migratory animals and their habitats. CMS brings together the States through which migratory animals pass, the Range States, and lays the legal foundation for internationally coordinated conservation measures throughout a migratory range.
The protection of migratory animals requires cooperation among multiple decision-making entities. These may include individual resource users or property owners, different government agencies within a single national or state jurisdiction, or the governments of different sovereign nations. The fate of the migratory animals, the values accruing to the various human actors, and the costs they bear, will depend on a suite of actions taken by several independent entitiesat different points in space and time. No single decision maker has full control over the set of human actions that will determine the overall status of the migratory species-or even the outcomes valued by that single decision maker. Recognizing this interdependence, human decision makers will tend to behave strategically. In other words, their decisions regarding the best way to achieve their individually-valued objectives will depend on the expected actions and reactions of the other relevant actors. This interplay can take a ...

It wouldnt let me get a photo, however. (Note: Merlin was originally called Smiths Corners. When the post office there opened in 1868, since there was another place in Ontario which already had that name, the community was renamed Merlin. One rumour has it that the name came from a village in Scotland, but another rumour is that it was named after Merlin the falcon, which had been seen in that area ...
Facts/Discussion. GCCS is a common operating environment (COE), integration standard, and migration strategy that eliminates the need for inflexible stovepipe command and control systems and expensive duplication. It is the migration of existing systems into a new COE connected across the Secret Internet Protocol Router Network (SIPRNET) and the integration of selected command and control (C2) systems into a comprehensive, interoperable system.. Its first priority is to demonstrate the C4IFTW concepts vision by becoming a globally connected, warrior-involved, interoperable, fully-integrated C4 system. The GCCS core consists of the basic functions required by the warfighter to plan, execute, and manage military operations. These functions are then satisfied by selecting the applications from existing C2 systems that best meet the requirement. This ensures interoperability, minimizes training requirements and allows efficient use of limited defense resources. GCCS has been identified by the ...

Downloadable! The focus of this paper is on the rural poor of south Asia and their struggle to cope with the seasonal risk of unemployment and the ensuing income risks. In the absence of formal credit or insurance markets the rural poor typically resort to, among other options, the following informal strategies to cope with seasonal income risks: (i) seasonal rural-to-urban migration, and (ii) mutual (ex-post) transfers between families of friends and relatives. Access to credit through a microfinance institution could also provide a competing source of insurance. The question raised in this paper is how the access to credit may affect the more traditional/time honoured means of risk coping, such as seasonal migration. Given that credit, i.e., a credit-financed activity, is potentially a substitute for seasonal migration, it is reasonable to argue that easy access to credit (or high return on credit) will lower the incidence of migration. However, there also exists a potential complementarity between

Dispersal and migration are superficially similar large-scale movements, but which appear to differ in terms of inter-individual behavioural synchronization. Seasonal migration is a striking example of coordinated behaviour, enabling animal populations to track spatio-temporal variation in ecological conditions. By contrast, for dispersal, while social context may influence an individuals emigration and settlement decisions, transience is believed to be mostly a solitary behaviour. Here, we review differences in drivers that may explain why migration appears to be more synchronized than dispersal.(...). View online ...

Every year in September the spectre of cold and flu season arrives. It has become a fact of life. We might as well allot for our sick days knowing that we will be hit at least once, if not two to three times before Springs arrival. In every office and in every family, there are those who get sick regularly and those who manage to stay healthy through it all. In Super Immunity, Dr. Fuhrman will explain why some of us get sick more regularly than others and offer a proven program to stay healthy through the year. Dr. Fuhrman argues that our current approach to disease is doing far more harm than good. He asserts that flu shots, antibiotics, supplements and alternative treatments are not the answer and can actually make us more sick. He explains why our current efforts are failing us. The truth is far too many have depleted or compromised immune systems. This is no surprise given antibiotics are prescribed with every cough and sniffle and it is too easy to get simply stuck in a vicious cycle of a ...

My understanding is that shipping lines have schedules for their ships. While I understand things can happen (storms, mechanical failure etc...) which would impact this schedule, I fail to understand how the company cannot give us an expected arrival date. They must have some sort of schedule otherwise how are they getting business? Most freighters have to have some kind of target arrival date otherwise companys wouldnt engage their services. ...
When the JavaScript requests the location via the GeoLocation API, its asking the device for the best location it can give. If the device has recently accessed the GPS, it may have cached the information, so it will return that immediately. However, if the device has not accessed the GPS for a long time, that location is considered "stale". In this case it will request another new position from the GPS, but will need to calculate that new position. Solving for a new position can take some time.. In cases like this sometimes the device returns an estimate based on the last position, the network location, or the database location. This can have more error than a GPS position.. ...

At the International Organization for Migration (IOM), the UNs Migration Agency I head, we deal with trafficking in persons on a daily basis. We know that trafficking involves more than kidnapping and selling of persons, people forced into jobs against their will, and victims forced to give away a kidney or other vital organs. Trafficking in persons can occur ever so subtly as in cases of employment pathways, where workers are charged for recruitment and placement fees, have their wages withheld, or cannot leave their employers and thus are put into vulnerable situations where they are further exploited and become trafficked. Migrants travelling on regular or irregular migration routes around the globe are highly vulnerable to these kinds of abuses. Many who start their journeys by willingly placing themselves in the hands of smugglers can also become victims of trafficking along the way.. In addition to our and our partners hands-on work in providing protection and assistance to already some ...
Amazing migrations require amazing mechanisms. We will talk about why animals migrate as well as how animals migrate. Much of migration relies upon accurate orientation and navigation.

The Greater Yellowstone Ecosystem lies in the path of some of the most significant wildlife migration routes on the planet. However, major challenges await migratory animals as they leave Yellowstone National Park. The long-term conservation of these animals depends on the actions of landowners and other stakeholders far beyond the national park’s borders. As part of the National Park Service’s centennial celebration, and in conjunction with the May issue of National Geographic magazine, “Invisible Boundaries” uses stunning photographs, immersive video, interactive migration maps, cultural objects, and original artwork to explore the compelling story behind some of the most amazing animal migrations on the planet. Come examine why animals make these incredible journeys and learn about the cutting-edge conservation science that’s taking place in one of America’s crowning natural treasures—Yellowstone National Park.

Overall, three main findings emerged. (i) Pigeons can discriminate magnetic compass directions with the left as well as the right eye. This suggests processing of magnetic compass information by either brain hemisphere. (ii) Brain systems associated with the left and the right eye seem to process magnetic cues differently. (iii) Regarding the correct detection of the goal direction, the right eye (left hemisphere) is superior, as in most other cases studied so far.. The first important finding is that pigeons are capable of magnetic compass orientation with the left as well as the right eye and, consequently, with both brain hemispheres. This contrasts with the findings in European robins (Wiltschko et al. 2002), silvereyes (Wiltschko et al. 2003) and domestic chicks (Rogers et al. 2008), but is in line with the recent findings in garden warblers (Hein et al. in press). Interestingly, Rogers et al. (2008) considered the possibility that either brain hemisphere of chicks might, in principle, be ...
The monarch butterfly (Danaus plexippus) is emerging as a model organism to study the mechanisms of circadian clocks and animal navigation, and the genetic underpinnings of long-distance migration. The initial assembly of the monarch genome was released in 2011, and the biological interpretation of the genome focused on the butterflys migration biology. To make the extensive data associated with the genome accessible to the general biological and lepidopteran communities, we established MonarchBase (available at http://monarchbase.umassmed.edu). The database is an open-access, web-available portal that integrates all available data associated with the monarch butterfly genome. Moreover, MonarchBase provides access to an updated version of genome assembly (v3) upon which all data integration is based. These include genes with systematic annotation, as well as other molecular resources, such as brain expressed sequence tags, migration expression profiles and microRNAs. MonarchBase utilizes a variety of

One of the continents best-studied and most familiar songbirds, the White-throated Sparrow is found at some season throughout much of North America south of the tree line and principally east of the Rocky Mountains. To many its distinctive whistled song is synonymous with the northern wilderness. During migration and throughout its winter range, this species is a common visitor at feeding stations. It breeds primarily in the boreal coniferous and mixed forest and, a short-distance migrant, winters mainly in the southeastern U.S. A habitat generalist, it tends to occur in shrubby edges or early successional stages or openings in the forest, nesting and foraging for seeds and insects on or near the ground.. Throughout its extensive range the White-throated Sparrow shows no subspecific variation. However, it exhibits plumage polymorphism (white-striped and tan-striped morphs - see color photos) in both sexes, most obvious in the breeding season, associated with a difference in an autosome. These ...
The genomics era has produced an arsenal of resources from sequenced organisms allowing researchers to target species that do not have comparable mapping and sequence information. These new non-model organisms offer unique opportunities to examine environmental effects on genomic patterns and processes. Here we use comparative mapping as a first step in characterizing the genome organization of a novel animal model, the white-throated sparrow (Zonotrichia albicollis), which occurs as white or tan morphs that exhibit alternative behaviors and physiology. Morph is determined by the presence or absence of a complex chromosomal rearrangement. This species is an ideal model for behavioral genomics because the association between genotype and phenotype is absolute, making it possible to identify the genomic bases of phenotypic variation. We initiated a genomic study in this species by characterizing the white-throated sparrow BAC library via filter hybridization with overgo probes designed for the chicken,

The mallard Anas platyrhynchos is a reservoir species for influenza A virus in the northern hemisphere, with particularly high prevalence rates prior to as well as during its prolonged autumn migration. It has been proposed that the virus is brought from the breeding grounds and transmitted to conspecifics during subsequent staging during migration, and so a better understanding of the natal origin of staging ducks is vital to deciphering the dynamics of viral movement pathways. Ottenby is an important stopover site in southeast Sweden almost halfway downstream in the major Northwest European flyway, and is used by millions of waterfowl each year. Here, mallards were captured and sampled for influenza A virus infection, and positive samples were subtyped in order to study possible links to the natal area, which were determined by a novel approach combining banding recovery data and isotopic measurements (delta H-2) of feathers grown on breeding grounds. Geographic assignments showed that the ...

Highly pathogenic avian influenza H5N1 remains a serious concern for both poultry and human health. Wild waterfowl are considered to be the reservoir for low pathogenic avian influenza viruses; however, relatively little is known about their movement ecology in regions where HPAI H5N1 outbreaks regularly occur. We studied movements of the ruddy shelduck (Tadorna ferruginea), a wild migratory waterfowl species that was infected in the 2005 Qinghai Lake outbreak. We defined their migration with Brownian Bridge utilization distribution models and their breeding and wintering grounds with fixed kernel home ranges. We correlated their movements with HPAI H5N1 outbreaks, poultry density, land cover, and latitude in the Central Asian Flyway. Our Akaike Information Criterion analysis indicated that outbreaks were correlated with land cover, latitude, and poultry density. Although shelduck movements were included in the top two models, they were not a top parameter selected in AICc stepwise regression results.

  • Adding to limited empirical data on the effects of infection on animal migrations, we show that Bewick's swans naturally infected with avian influenza virus delayed departure and traveled shorter distances during spring migration compared to uninfected individuals. (cie-deakin.com)
  • The active, or directional, migrations of fishes (spawning, feeding, and wintering) are among the most characteristic features of their life cycle. (thefreedictionary.com)
  • Scientists today still attach tags, such as metal bands, to track movement of animals. (wikipedia.org)
  • Scientists can track the locations and movement of the tagged animals without recapturing them using this RFID technology or satellites. (wikipedia.org)
  • Satellite tracking is especially useful because the scientists do not have to follow after the animal nor do they have to recover the tag to get the data on where the animal is going or has gone. (wikipedia.org)
  • Every night across the world's oceans, numerous marine animals arrive at the surface of the ocean to feed on plankton after an upward migration of hundreds of metres. (nature.com)
  • Our findings reveal that these animals generally constitute a greater fraction of total plankton abundance in the clear subtropical gyres, consistent with the idea that the avoidance of visual predators is an important life strategy in these regions. (nature.com)
  • Such anadromous migrations are primarily characteristic of fishes inhabiting the northern hemisphere, for example, the Clupeidae, Salmonidae, and Acipenseridae. (thefreedictionary.com)
  • Come examine why animals make these incredible journeys and learn about the cutting-edge conservation science that's taking place in one of America's crowning natural treasures-Yellowstone National Park. (nationalgeographic.org)
  • Freshwater fishes also make short spawning migrations. (thefreedictionary.com)
  • The success or failure of individual animals to make the journey is usually needed for them to reproduce. (wikipedia.org)
  • With the help of 40 GPS and cellphone-outfitted animals over the past decade, researchers discovered that herds are willing to avoid food if it means escaping the detection of humans. (scientificamerican.com)
  • Wildebeests and zebras alike went farther out of their way to dodge people than to avoid even animal predators like hyenas or lions-decisions that appear to be profoundly affecting their migration patterns. (scientificamerican.com)
  • The endocrine system is the key mediator of environmental and developmental (internal) information, and is likely to be involved in altering the performance of animals when selection has favored phenotypic plasticity. (usgs.gov)
  • To keep track of the signal, the scientist follows the animal using the receiver. (wikipedia.org)
  • This approach of using radio tracking can be used to track the animal manually but is also used when animals are equipped with other payloads. (wikipedia.org)
  • Networks, or groups, of satellites are used to track animals. (wikipedia.org)
  • This most recent sequence of geologic time is somewhat complicated to describe in terms of animal science since there is much more information available from the fossil record. (encyclopedia.com)
  • A type section is a place that is considered to be the first discovered well-defined area in which evidence of a time-period shift, or difference between plant and animal communities, can be observed. (encyclopedia.com)
  • In contrast, the genetic architecture and molecular mechanisms that underlie the migratory phenotype, including flight direction/orientation and timing of their migration, remain poorly understood. (biologists.org)
  • You may have noticed that in recent years more and more of these books have focused on the lives of animals. (washingtonpost.com)
  • His earlier work, particularly his intimate descriptions of the lives of the ravens that are his neighbors in the Maine woods, offered just the sort of weaving of human and animal concerns that makes this sort of writing come alive - again, not anthropomorphizing so much as establishing relevance to humans, the only animals that read, after all - and the new book's introduction promised more of the same. (washingtonpost.com)
  • Take time to learn more about the lives of animals. (pbs.org)
  • Migratory niche shifts and metamorphic events are extreme examples of the role of hormones in animal performance and represent one end of a continuum. (usgs.gov)
  • Hopcraft said the migration study underscores how 'catastrophic' a road would be to the Serengeti's animals, forcing them to cross the road to access the Mara River, their only source of water in the dry season. (scientificamerican.com)
