Isolation and characterization of Vibrio parahaemolyticus causing infection in Iberian toothcarp Aphanius iberus. (1/216)

High mortality among laboratory cultured Iberian toothcarp Aphanius iberus occurred in February 1997 in Valencia (Spain). The main signs of the disease were external haemorrhage and tail rot. Bacteria isolated from internal organs of infected fish were biochemically homogeneous and identified as Vibrio parahaemolyticus. The bacteria were haemolytic against erythrocytes from eel Anguilla anguilla, amberjack Seriola dumerili, toothcarp A. iberus and humans, and were Kanagawa-phenomenon-negative. Infectivity tests showed that the virulence for A. iberus was dependent on salinity. Finally, all strains were virulent for amberjack and eel.  (+info)

Multiple binding sites in the growth factor receptor Xmrk mediate binding to p59fyn, GRB2 and Shc. (2/216)

Melanoma formation in Xiphoporus is initiated by overexpression of the EGFR-related receptor tyrosine kinase Xmrk (Xiphoporus melanoma receptor kinase). This receptor is activated in fish melanoma as well as in a melanoma-derived cell line (PSM) resulting in constitutive Xmrk-mediated mitogenic signaling. In order to define the underlying signaling pathway(s), triggered by the activated Xmrk receptor, we attempted to identify its physiological substrates. Examination of the Xmrk carboxyterminus for putative tyrosine autophosphorylation sites revealed the presence of potential binding motifs for GRB2 as well as for Shc. Binding of these adaptor proteins to the Xmrk receptor was detected in vitro and in cells expressing the mrk kinase. The GRB2 and Shc interactions with the receptor could be disrupted individually by phosphotyrosine peptides containing putative Xmrk autophosphorylation sites, indicating direct binding of both proteins. Recruitment of GRB2 by the constitutively activated Xmrk receptor led to strong MAP kinase activation in Xiphoporus melanoma cells. We also identified a high-affinity binding site for src-kinases (pYEDL) in the Xmrk carboxyterminus. Competition experiments with phosphopeptides comprising this site confirmed that it is used for high-affinity binding of Xiphoporus fyn (Xfyn) to Xmrk in melanoma cells. Thus, Xmrk can initiate different signaling pathways by using multiple substrate-binding sites to trigger proliferation of pigment cells.  (+info)

Female preferences in a fish genus without female mate choice. (3/216)

The evolution and the adaptive logic (if any) of female mate choice are subjects of lively debate. Whereas most researchers believe that females have evolved to recognize signs of male 'quality' (the ability to provide females or their offspring with direct or indirect genetic or material benefits), there is intriguing evidence that males can evolve to appeal to pre-existing female preferences. Evidence for these pre-existing biases is often ambiguous because phylogenetic reconstructions have usually failed to establish conclusively whether the female preference or the favored male traits evolved first. This potential difficulty is minimal in the mosquitofish genus Gambusia, none of whose 45 species appears to have a female-choice mating system in the wild, and none of which shows the male behavioral and morphological traits that are characteristic of female choice. Nevertheless, in an experimental situation in the laboratory, female Gambusia holbrooki readily chose between models of males and demonstrated significant and reliable preferences for a variety of exaggerated male traits that are not seen in their species or their genus. Other morphological alterations were not preferred. The latent willingness of females to choose traits in a genus without such traits and without evident female choice in the wild is remarkable and may indicate a pre-existing bias in females that is ready to drive male evolution, should the social system or the ecological variables that control it change.  (+info)

Model ecosystem evaluation of the environmental impacts of the veterinary drugs phenothiazine, sulfamethazine, clopidol, and diethylstilbestrol. (4/216)

Four veterinary drugs of dissimilar chemical structures were evaluated for environmental stability and penchant for bioaccumulation. The techniques used were (1) a model aquatic ecosystem (3 days) and (2) a model feedlot ecosystem (33 days) in which the drugs were introduced via the excreta of chicks or mice. The model feedlot ecosystem was supported by metabolism cage studies to determine the amount and the form of the drug excreted by the chicks or mice. Considerable quantities of all the drugs were excreted intact or as environmentally short-lived conjugates. Diethylstilbestrol (DES) and Clopidol were the most persistent molecules, but only DES bioaccumulated to any appreciable degree. Phenothiazine was very biodegradable; sulfamethazine was relatively biodegradable and only accumulated in the organisms to very low levels. Data from the aquatic model ecosystem demonstrated a good correlation between the partition coefficients of the drugs and their accumulation in the fish.  (+info)

Comparative structure and characterization of a CDKN2 gene in a Xiphophorus fish melanoma model. (5/216)

We have cloned, sequenced, and characterized the RNA expression properties of a fish CDKN2 gene from Xiphophorus helleri and X. maculatus. This gene, termed CDKN2X, shows a high degree of amino acid sequence similarity to members of the mammalian CDKN2 gene family, which includes the tumor suppressor loci CDKN2A (P16) and CDKN2B (P15). Comparative sequence analysis suggests that fish CDKN2X is similarly related to all four mammalian gene family members, and may represent a descendant of an ancestral prototypic CDKN2 gene. CDKN2X was mapped to a region on autosomal Xiphophorus linkage group V (LG V) known to contain the DIFF gene that acts as a tumor suppressor of melanoma formation in X. helleri/X. maculatus backcross hybrids. Thus, CDKN2X may be a candidate for the tumor suppressor DIFF gene. Here we have sequenced CDKN2X in both Xiphophorus species and have characterized its expression in normal and melanotic tissues within control and backcross hybrid fish. A simultaneous expressional analysis of the Xmrk-2 tyrosine kinase receptor gene, which is strongly implicated in melanomagenesis in this system, was also performed. RT - PCR analyses revealed that both genes were highly expressed in melanomas. For CDKN2X, this result contrasts numerous findings in human tumors including human melanoma in which either CDKN2A (P16) deactivation or LOH was observed.  (+info)

Melanoma loss-of-function mutants in Xiphophorus caused by Xmrk-oncogene deletion and gene disruption by a transposable element. (6/216)

The overexpression of the Xmrk oncogene (ONC-Xmrk) in pigment cells of certain Xiphophorus hybrids has been found to be the primary change that results in the formation of malignant melanoma. Spontaneous mutant stocks have been isolated that have lost the ability to induce tumor formation when crossed with Xiphophorus helleri. Two of these loss-of-function mutants were analyzed for genetic defects in ONC-Xmrk's. In the lof-1 mutant a novel transposable element, TX-1, has jumped into ONC-Xmrk, leading to a disruption of the gene and a truncated protein product lacking the carboxyterminal domain of the receptor tyrosine kinase. TX-1 is obviously an active LTR-containing retrotransposon in Xiphophorus that was not found in other fish species outside the family Poeciliidae. Surprisingly, it does not encode any protein, suggesting the existence of a helper function for this retroelement. In the lof-2 mutant the entire ONC-Xmrk gene was found to be deleted. These data show that ONC-Xmrk is indeed the tumor-inducing gene of Xiphophorus and thus the critical constituent of the tumor (Tu) locus.  (+info)

The non-LTR retrotransposon Rex3 from the fish Xiphophorus is widespread among teleosts. (7/216)

Rex3, the first reverse transcriptase (RT)-encoding retrotransposon isolated from the melanoma fish model Xiphophorus, is a non-long-terminal-repeat element related to the RTE family. The essential features of Rex3 are (1) an endonuclease and a reverse transcriptase, (2) 5' truncations of most of the copies, (3) a 3' tail consisting of tandem repeats of the sequence GATG, and (4) short target site sequence duplications of variable length. Compilation of Rex3 sequences from the pufferfish genome project suggested that, as observed for other members of the RTE family, no additional large open reading frame was present upstream of the endonuclease/reverse transcriptase open reading frame. There are about a thousand copies of Rex3 in the haploid genome of Xiphophorus, some of them probably resulting from recent retrotransposition events. Rex3 RNA was detected by RT-PCR in melanoma and in nontumorous tissues, as well as in melanoma-derived and embryonic cell lines. Rex3 is present in a broad panel of teleost species and was found in the promoter region and in introns of various genes. To our knowledge, Rex3 is the first autonomous retrotransposon described to date which is widespread in teleosts. This wide distribution and occasional association with coding sequences may confer on Rex3 a predisposition to play a role in genome evolution in teleosts.  (+info)

Effects of nonylphenol and 17beta-estradiol on vitellogenin synthesis and testis morphology in male platyfish Xiphophorus maculatus. (8/216)

Nonylphenol has been found to exert estrogenic effects in fish and may influence the fertility of male fish. In the present study, the effects of nonylphenol and 17beta-estradiol on vitellogenin synthesis and testis morphology in platyfish Xiphophorus maculatus were investigated. Vitellogenin was observed in the plasma of all fish exposed to nonylphenol or 17beta-estradiol. Exposure to 17beta-estradiol resulted in a significant reduction in the gonadosomatic index. A tendency for a dose-dependent reduction in the gonadosomatic index in the nonylphenol exposed groups was observed. Histological examination revealed dose-dependent effects of nonylphenol on the testis structure. The testes of control fish contained numerous cysts with spermatogenetic cells. The testes of fish exposed to nonylphenol or 17beta-estradiol showed a decrease in the number of cysts concomitant with an increase in the amount of hypertrophied Sertoli cells present. Formation of spermatozeugmata is compulsory for this species, but free spermatozoa were observed in the efferent ducts of the treated fish. The study indicates that nonylphenol has estrogenic potency, and that both nonylphenol and 17beta-estradiol have marked effects on the testis morphology of X. maculatus. The ambient concentration of nonylphenol was measured by high pressure liquid chromatography during the experiment. The measurements revealed that the actual concentrations of nonylphenol in the water were about 30-40 % of the nominal concentrations.  (+info)

The morphologic development of the gonopodium of male mosquitofish, Gambusia holbrooki, is essential for proper reproductive function and has previously been used as a biomarker for the presence of endocrine-disrupting chemicals (EDCs) in freshwater systems. The development of the gonopodium is accompanied by the modification of the hemal spines on the 14th, 15th, and 16th vertebrae. These form an anchor for the movement of the gonopodium, and their normal development is therefore critical. This development is under hormonal control. It has been hypothesized that the modification of the hemal spines may be used as an end point for understanding the effects of exposure of early-life stage fish to EDCs and to add to the understanding of the differential sensitivities of different life stages. Larval fish were exposed to concentrations (0, 20, 100, and 500 ng/L) of 17b-estradiol (E2) in two experiments using a flow-through system for 8 and 12 weeks. There was a general delay in the development of ...
HOWELL, Dylan H; WOODFORD, Darragh J; WEYL, Olaf LF y FRONEMAN, William. Population dynamics of the invasive fish, Gambusia affinis, in irrigation impoundments in the Sundays River Valley, Eastern Cape, South Africa. Water SA [online]. 2013, vol.39, n.4, pp.00-00. ISSN 1816-7950.. The alien invasive Gambusia affinis is one of the most widely introduced fish species on the planet, and has established in freshwater ecosystems across South Africa. The invasion ecology and, in particular, the population dynamics of the species in this country are, however, poorly understood. In this study the relative abundance and population dynamics of G. affinis were quantified in 5 interconnected irrigation impoundments within the Sundays River Valley, Eastern Cape. Four fish surveys were conducted from early summer (February 2012) to early winter (June 2012). Repeated-measures ANOVA analyses on the catch per unit effort (CPUE) of G. affinis between sampling events and dams revealed significant differences in ...
We sequenced and assembled the genome of the mosquitofish, Gambusia affinis, using short read Illumina data from paired-end and in vitro proximity-ligation Chicago libraries. The resulting genome assembly had high coverage, improved contigs, and long scaffold sizes compared to other assemblies that used Illumina mate-paired libraries (Poecilia reticulata; Künstner et al. 2016), assemblies that utilized Roche 454 long insert sequencing (Xiphophorus maculatus; Schartl et al. 2013), or multiple types of sequencing reads, including PacBio reads (Pootakham et al. 2017). The Chicago library improves the scaffold contiguity because it provides links between genomic regions hundreds of kb apart and uses information about proximity ligation libraries to obtain a highly continuous genome assembly (Putnam et al. 2016). The result is a high-quality genome sequence composed of 26 (N50) scaffolds, just more than the haploid number of chromosomes (n = 24; Chen and Ebeling 1968). Our genome assembly was 598.7 ...
Background: One of Darwins chosen examples for his idea of sexual selection through female choice was the sword, a colourful extension of the caudal fin of male swordtails of the genus Xiphophorus. Platyfish, also members of the genus Xiphophorus, are thought to have arisen from within the swordtails, but have secondarily lost the ability to develop a sword. The sustained increase of testosterone during sexual maturation initiates sword development in male swordtails. Addition of testosterone also induces sword-like fin extensions in some platyfish species, suggesting that the genetic interactions required for sword development may be dormant, rather than lost, within platyfish. Despite considerable interest in the evolution of the sword from a behavioural or evolutionary point of view, little is known about the developmental changes that resulted in the gain and secondary loss of the sword. Up-regulation of msxC had been shown to characterize the development of both swords and the ...

Sixteen populations, each of four male and four female green swordtail fish, were ob-served in 54 litre tanks separated into two unequal volumes by a partition allowing swim-ming from one area to another only at the surface. Each population was observed on 2 4 occasions, making a combined total of 50 observation periods of 2 hours each. Chase right orders, spatial positions as well as several agonistic and epigamic behaviour units were noted during each period of observation. Males and females apparently form distinct hierarchies which are perfectly linear and transitive in 68% and 42% of the cases respec-tively. Some dominance structures are incomplete, but no intransitivity is noted. Alpha males are much more aggressive than their isosexual subordinates. In females, the fre-quency of aggressive behaviour appears to be more proportional to the social rank of the initiator, but the number of chases received from other females is the best indicator of rank in the female hierarchies. Alpha males ...

Pregnancy is a tiring affair and as you reach full-term you could be forgiven for avoiding confrontation to conserve energy. However, picking your battles does not seem to be a priority for live-bearing female mosquitofish, Gambusia holbrooki: according to Frank Seebacher from the University of Sydney, Australia, they get more aggressive towards the end of their pregnancy (p. 771).. Female mosquitofish are naturally feisty, vying to become dominant over other fish in order to attract more suitors. However, this behaviour is energetically costly, especially when confrontations can escalate into high-speed chases with the two fish nipping at each other. Seebacher reasoned that given the amount of energy needed to fuel these aggressive encounters, females in the late stages of pregnancy would become more docile as most of their energy would be needed to support the increasing metabolic burden of their growing offspring.. Teaming up with Ashley Ward from the University of Sydney and Robbie Wilson ...

Karyotypes of 65 species of the genus Nothobranchius Peters, 1868 were reviewed and of those 35 examined first time. The results of present study have shown that fishes of the genus Nothobranchius possessed highly diverse karyotypes. The diploid chromosome number (2n) ranged from 16 to 50. The most frequent 2n was 2n = 36 (in 35 species) while the second one 2n = 38 (in 13 species). Proportion of biarmed chromosomes varied from 0 to 95% between species. Diploid chromosome number variability apparently exists as a result of chromosomal fusions or fissions and extensive karyotypic formula alterations promoting by inversions. Multiple sex chromosomes of system X1X1X2X2/X1X2Y type were found only in karyotypes of 5 species. The extensive karyotype variability, unusual for teleosts, of genus Nothobranchius can be likely associated with the characteristics of its life cycle and inhabiting under unstable environment of East African savannah temporal pools.
A large variety of sex determination systems have been described in fish. However, almost no information is available about sex determination in the classical fish models, the zebrafish Danio rerio and the pufferfish Takifugu rubripes. A DNA-binding protein gene called dmrt1bY (or DMY) has been recently described as an outstanding candidate for the primary sex-determining gene in the medaka fish Oryzias latipes. But this gene is not the universal master sex-determining gene in teleost fish, since dmrt1bY is not found in most other fishes. Hence, other fish models need to be examined including the platyfish Xiphophorus maculatus. Xiphophorus maculatus has three types of sex chromosomes (X, Y and W; females are XX, WX or WY; males are XY or YY). Its gonosomes are at an early stage of differentiation. The sex-determining locus on the sex chromosomes is flanked by two receptor tyrosine kinase genes, the Xmrk oncogene and its protooncogenic progenitor gene egfrb, which both delimit a region of about ...
Desert springs, which harbor diverse and endemic invertebrate assemblages, are often used as refuge habitats for protected fish species. Additionally, many of these springs have been colonized by invasive fish species. However, the potential impacts of recently established fish populations on invertebrate communities in desert springs have been relatively unexplored. We conducted a mesocosm experiment to assess the impact of both protected and invasive fish on community structure of spring-dwelling invertebrates focusing on zooplankton. Experimental populations of spring zooplankton communities were established and randomly assigned to one of three treatments, (1) invasive western mosquitofish (Gambusia affinis); (2) endangered Mohave tui chub (Siphateles bicolor mohavensis); and (3) fishless control. Final populations of zooplankton and fish were sampled, sorted, identified and counted. The treatment differences of zooplankton communities were analyzed by comparing the densities of six major
The history of Bahamas mosquitofish is written in their genitals. Though youd have a hard time locating a female fishs reproductive parts, they tell a story of predators, suitors, and finding a way to regain control.. Gambusia hubbsi arrived at Andros Island, in the Bahamas, about 15,000 years ago. The little fish live in vertical, water-filled caves called blue holes. Populations separated from each other by these caves are in the process of evolving into different species, pushed by the pressures of their particular homes. For example, in some blue holes, the fish live with few threats. In others, mosquitofish swim alongside their predator, a fish called the bigmouth sleeper (Gobiomorus dormitor). The color, shape, and swimming performance of mosquitofish have all evolved differently depending on whether these predators are around.. Another trait evolving differently across mosquitofish populations is their genitals. In the past, researchers studying mosquitofish-and other rapidly changing ...
African annual killifish Nothobranchius furzeri is an established model species in many fields of research with special emphasis on aging. It is shortest-lived and rapidly aging species with spontaneous age-dependent carcinogenesis, what makes N. furzeri exceptional among vertebrates. In pilot experiment with highly inbred and extremely short-lived strain we already described incidence of liver and kidney neoplasia. According to our preliminary data from new generation sequencing (exome sequencing), there is considerable number of mutations in genes related to the processes involved in malignant transformation. The aim of present project is to discover driver mutations in tumour suppressor genes and oncogenes and verify their role in kidney and liver tissue carcinogenesis. To detect and characterise key mutations accompanying malignant transformation whole genome sequencing (WGS) will be used. Finally, we will assess the role of selected candidate oncogenes and tumour suppressor genes in vivo by ...

This experiment consisted of 75 different pairs composed of two male adults Xiphophorus helleri meeting each other twice. On the first occasion, one of the fish was familiarized with the meeting place for 3h (resident) while its opponent was familiarized with another aquarium (intruder). Upon dominance of one individual over the other, the pair members were separated and returned to their respective home groups for 168 hours (7 days). After this period of separation, the same pair members were reunited and met while roles had been reversed: the initial resident became the intruder, and the initial intruder was given prior-residency. Individuals in the initial resident role defeated the initial intruder in a significant majority of cases (76%). On their second meeting, the newly established dominance relationship was noted in favour of the new resident in a significant majority of cases (82%), and in a reversed direction as compared to the initially established dominance order. This shows that ...

Molecular Phylogenetics and Evolution, 61: 854-865.. http://www.sciencedirect.com/science/artic…055790311003472. Abstract. The genus Pangio is one of the most species-rich of the loach family Cobitidae and widespread across South and Southeast Asia. Its species diversity has never been studied under a clear phylogenetic approach, but four species-groups were proposed according to the most obvious morphological characters. We present here phylogenetic analyses of the genus Pangio based on sequence data of the mitochondrial cytochrome b gene, the nuclear recombination-activating gene 1 (RAG 1) and a combined dataset of 109 specimens from 18 morphologically identified species across the whole distribution area of the genus. Our data reveal the existence of three major lineages within Pangio. Two of our major lineages were congruent with formerly ...
Monday, April 7, 2014. Swarms of mosquitoes buzzing around people after dusk is a familiar scene on almost every city street. So World Health Organisations (WHO) theme for World Health Day on Monday will clearly strike a chord in Chennai. WHO has identified vector diseases as biggest threat to health and have started a campaign with the tagline Small bite, big threat. We are fed up with this mosquito menace. We have to close our doors and windows by dusk. It becomes very uncomfortable because of the high night temperatures. Mosquito repellants and coils no longer seem to work, said S Ramesh, a resident of Nandanam. Poor desilting of drains and waterways and irregular garbage clearance has compounded to the problem. B M Rex, entomologist, Spartan Enterprises, said: Its surprising that there is a rise in the mosquito population even without rains. The stagnant water and overflowing drains are the main breeding grounds for mosquitoes. The corporation should release gambusia fish into the ...

Since 1978, over 6000 research publications have appeared on the biology of the livebearing fishes (Family Poeciliidae), characterizing, phylogenetic relationships, ecology, behavior, life histories, morphology, environmental toxicology, and developing their potential as a model system for cancer biology. Because so much is known about these fish in their natural environments, and because they provide such convenient experimental systems, they are poised to become a premier system for evolutionary and functional genomics. Several striking phenomena within the family indicate it can become a model system for investigating sex-chromosome evolution, maintenance of genetic variation, gene regulation, and the genetic bases of life history, behavioral, and morphological evolution. Surprisingly though, very little is known about poeciliid genomes, and few molecular tools are available. We therefore propose to bring together poeciliid biologists, molecular biologists, geneticists and genomicists to ...

The lipid composition of cell membranes is linked to metabolic rate and lifespan in mammals and birds but very little information is available for fish. In this study, three fish species of the short-lived annual genus Nothobranchius with different maximum lifespan potential (MLSP) and the longer-lived outgroup species Aphyosemion australe were studied to test whether they conform to the predictions of the longevity- homeoviscous adaptation (LHA) theory of ageing. Lipid analyses were performed in whole-fish samples and the peroxidation index (PIn) for every phospholipid (PL) class and for the whole membrane was calculated. Total PL content was significantly lower in A. australe and N. korthausae, the two species with the highest MLSP, and a negative correlation between membrane total PIn and fish MLSP was found, meaning that the longer-lived fish species have more saturated membranes and, therefore, a lower susceptibility to oxidative damage, as the LHA theory posits.. ...
The epidermal growth factor receptor (Egfr) with its numerous ligands has fundamental roles in development, cell differentiation and physiology. Dysfunction of the receptor-ligand system contributes to many human malignancies. Consistent with such various tasks, the Egfr gene family has expanded during vertebrate evolution as a consequence of several rounds of whole genome duplication. Of particular interest is the effect of the fish-specific whole genome duplication (FSGD) on the ligand-receptor system, as it has supplied this largest group of vertebrates with additional opportunities for sub- and/or neofunctionalization in this signaling system. We identified the predicted components of the Egf receptor-ligand signaling system in teleost fishes (medaka, platyfish, stickleback, pufferfishes and zebrafish). We found two duplicated egfr genes, egfra and egfrb, in all available teleost genomes. Surprisingly only one copy for each of the seven Egfr ligands could be identified in most fishes, with zebrafish

Fische der Gattung Xiphophorus stellen eines der am besten untersuchten Modellsysteme zur Untersuchung genetischer Geschlechtsbestimmung innerhalb dieser Klasse von mehr als 24.000 Arten dar. X. maculatus kann männliche (XX/ XY) oder weibliche (WY/ YY) Heterogametie aufweisen. Zusätzlich sind atypische Geschlechtsbestimmungssysteme beschrieben worden, die auf autosomale Modifikatoren zurückgeführt wurden. Obwohl kürzlich das Mastergen der Geschlechtsbestimmung im Medaka (Oryzias latipes) als ein Mitglied der Dmrt-Genfamilie identifiziert wurde, konnte Dmrt1bY als Mastergen der Geschlechtsbestimmung von Xiphophorus und anderen Fischen ausgeschlossen werden. Xiphophorus wurde zum wissenschaftlichen Modellsystem, da bestimmte zwischenartliche Kreuzungshybride maligne Melanome entwickeln. Das dafür verantwortliche Onkogen Xmrk und sein physiologisches Gegenstück egfrb liegen eng gekoppelt (| 0,6 cM) in der Geschlechtsbestimmungsregion von X. maculatus.

It is not clear whether fast and slow phenotypes have effectively equal fitness under fully aquatic conditions, or whether there are situations that would favour the fast Belize phenotype. One limitation to our microcosm experiment was that fish were unable to disperse. The natural habitat of mangrove rivulus and other rivuline killifishes typically consists of a mosaic of small, intermittent pools (Turko and Wright, 2015; Furness et al., 2018; Sutton et al., 2018). A high metabolic rate is often correlated with high boldness and activity (e.g. Killen et al., 2011; Gangloff et al., 2017), and perhaps Belize fish are more likely to leave water and disperse to unoccupied habitats. We have previously found that metabolic rate of K. marmoratus was positively associated with the frequency of emersion behaviour (Turko et al., 2018). Embryo production by Belize fish was the highest of any strain in our laboratory colony, typical of a dispersal phenotype. Furthermore, when embryo production in the ...
Members of the annual killifish genus Austrolebias live in temporary ponds across South America and possess a remarkable life cycle. These fish live in small ponds that dry out completely; killing the adults but not before they have laid eggs in the substrate of their pond. The desiccation-resistant eggs develop during the dry season, going through multiple stages of diapause until the next wet season rains trigger hatching and the cycle is repeated. There is considerable variation in size in Austrolebias, the largest species can reach up to 150mm in length while the typical size is just 40mm. Phylogenetic trees and species distribution models were built and used together to identify the factors that influence patterns of co-occurrence within this genus. Differences in growth and morphology among Austrolebias species were examined to quantify how differences in growth pattern can lead to the large variation in size and shape seen within the genus. Genomic data was generated for hybrid offspring ...
From an egg smaller than the size of half a thumbnail, to a tail-wagging, debris-eating wriggler, to a somersaulting tumbler, the mosquito undergoes a series of transformations and emerges in its most well-known and only terrestrial form: the adult mosquito.. Common vector control practices include using bio-pesticides or planting mosquito fish - which eat the larvae on the surface of the water - in self-contained man-made bodies of water such as pools, ornamental ponds and animal troughs.. In Albany, vector control officials provide a couple of residents with chicken flocks and an abundance of food for the animals. In return, the officials take blood samples from the chickens every two weeks from April through early November to test for the West Nile Virus and other mosquito-spread diseases.. ...

Neuropeptides are a diverse assemblage of signalling molecules that have key roles in the regulation of behaviour. Understanding the evolutionary relationships and functions of the plethora of neuropeptides has presented a considerable challenge to biologists. Based on presentations and discussions at a Royal Society meeting in 2017, three companion Review articles by Elphick et al., Jékely et al. and DeLaney et al. discuss advances in our knowledge of neuropeptide evolution and function and the techniques that have facilitated progress in this field of research.. ...

(1995) described two morphs in this species: independent males have a territorial breeding strategy of defending lek mating courts against other independents while satellites, which are non-territorial, move among, are recruited to and share independents courts. Jukema and Piersma (2006) added a third, namely faeder: Faeders are slightly larger than females and in late April have testes 2.5 time the size of testes of normal males. On leks in aviaries and in the wild they appear to combine feminine and masculine behaviours. Faeders may represent the ancestral, care-giving, male strategy, but their relatively large testes suggest that currently they behave as sneakers.

It is therefore considered important to breed both populations in allopatric conditions [separated] until this point can be clarified.. History. L. Seegers describes the discovery of N.fuscotaeniatus in an article published in DATZ (1998). He considers it to be the result of a lucky day. Coming from a collecting trip in southern Tanzania, and because the first part of his mission had been more productive than anticipated, he could spare one day. He therefore decided to spent some time in the Selous Game Reserve and photograph some African wildlife. In order to reach the lodge, coming from the south, one has to cross the Rufiji River either at Ndundu along the lower-river or about 60-km more stream upwards at Utete. As on arrival at the crossroad, the day was already fairly advanced and because he could not reach the ferry at Ndundu in time, he decided to make the crossing at Utete; pass the night there and continue the journey, first thing next morning.. The local guesthouse in Utete was still ...

The basic structure of eyes that we see today was present during the Cambrian era, but there is a lot of variety. The male version of the mayfly has a large compound eye which allows it to watch the sky for the form of a female. The four-eyed fish is able to look up to the surface of the water, and also keep watch below for any danger. Human eyes are fast, but birds of prey have superior resolution.. Nilssons research has shed light on an ongoing debate about the evolution of eyes. Some scientists believed there were many origins; others suggested there was only one step in their evolution. This latter idea was based on the discovery of a gene, called Pax6, which controls the development of eyes.. They are all right. The eyes of many organisms have evolved from Nilssons first stage. All eyes begin with the same building block, a protein called an opsin. Opsins hold a chromophore which is able to take in the energy of a photon. The chromophore and the opsin set off the start of ...

Each of the dorsal finlets has bifid (double-edged) tips, and are the only fins with spines; the rest of the fins are composed of soft rays. The body is covered in thick, bonelike, and rhombic (ganoid) scales. Their jaw structure more closely resembles that of the tetrapods than that of the teleost fishes. Bichirs have a number of other primitive characteristics, including fleshy pectoral fins superficially similar to those of lobe-finned fishes.[1] They also have a pair of slit-like spiracles on the top of their heads that are used to breathe air,[5] two gular plates, and paired ventral lungs (the left lung shorter than the right).[6] Four pairs of gill arches are present.[7] Bichirs have a maximum body length ranging from 25 cm (9.8 in) to over 100 cm (39 in) depending on specific species and morphology.[8] ...

Monophyly of this order is recognized on the basis of several derived characters: e.g., caudal fin symmetrical, supported internally by one epural; first pleural rib on second vertebrae rather than third; primitively, low-set pectoral girdle with a scalelike postcleithrum; an alveolar arm of the premaxillae; extended developmental period. In addition, they possess the following characters: lateral line canal and pores chiefly on head, lateral line represented on body only by pitted scales; narial opening paired; branchiostegal rays 3-7; pelvic fins and girdle present or absent; upper jaw bordered by premaxilla only, protrusible; vomer usually present and supracleithrum always present; metapterygoid usually absent and ectopterygoid always absent; parietals present or absent; vertebrae 24-54.

Karyotypes of 65 species of the genus Nothobranchius Peters, 1868 were reviewed and of those 35 examined first time. The results of present study have shown that fishes of the genus Nothobranchius possessed highly diverse karyotypes. The diploid chromosome number (2n) ranged from 16 to 50. The most frequent 2n was 2n = 36 (in 35 species) while the second one 2n = 38 (in 13 species). Proportion of biarmed chromosomes varied from 0 to 95% between species. Diploid chromosome number variability apparently exists as a result of chromosomal fusions or fissions and extensive karyotypic formula alterations promoting by inversions. Multiple sex chromosomes of system X1X1X2X2/X1X2Y type were found only in karyotypes of 5 species. The extensive karyotype variability, unusual for teleosts, of genus Nothobranchius can be likely associated with the characteristics of its life cycle and inhabiting under unstable environment of East African savannah temporal pools.
