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 ...
Influence of certain eco-physiological factors on predation efficiency of Gambusia affinis (Baird and Girard) on Culicine mosquito larvae
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 ...

The impact of environmental conditions on the expression of genetic variance and on maternal effects variance remains an important question in evolutionary quantitative genetics. We investigate here the effects of early environment on variation in seven adult life history, morphological, and secondary sexual traits (including sperm characteristics) in a viviparous poeciliid fish, the mosquitofish Gambusia holbrooki. Specifically, we manipulated food availability during early development and then assessed additive genetic and maternal effects contributions to the overall phenotypic variance in adults. We found higher heritability for female than male traits, but maternal effects variance for traits in both sexes. An interaction between maternal effects variance and rearing environment affected two adult traits: female age at maturity and male size at maturity. But there was no evidence of trade-offs in maternal effects across environments. Our results illustrate (i) the potential for pre-natal ...

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. Marked sexual dimorphism with the males often brightly colored ...
Fish of the genus Xiphophorus belong to the oldest animal models in cancer research. The oncogene responsible for the generation of spontaneous aggressive melanoma encodes for a mutated epidermal growth factor receptor (Egfr) and is called xmrk for Xiphophorus melanoma receptor kinase. Xmrk constitutive activation mechanisms and subsequent signaling pathways have already been investigated and charaterized but it is still unknown if Egfr ligands may also play a role in Xmrk-driven melanoma formation. To investigate the potential role of Egfr ligands in Xmrk-driven melanoma, I firstly analyzed the evolution of teleost and tetrapod Egfr/Egfr ligand systems. I especially focused on the analysis on the medaka fish, a closely related species to Xiphophorus, for which the whole genome has been sequenced. I could identify all seven Egfr ligands in medaka and could show that the two teleost-specific Egfr copies of medaka display dissimilar expression patterns in adult tissues together with differential ...

I saw one of these a few months ago at a vineyard west of Austin, which is around the eastern edge of their range. Quite an attractive lizard. Animal ssex and reproduction sometimes takes strange forms indeed. Consider theAmazon molly, a kinky relative of he popular aquarium fish. They are all female and reproduce by parthenogenesis, but they need to mate with a male of another species to initiate cell division in their ova. They usually mate with P. latipinna, the wild strain of the fish we fishkeepers know and love, but they will even mate with Gambusia if nothing else is around. That must be amusing to watch as a female molly is about 8-27 times the weight of a male gambusia.. ...
Colourful aquarium fish known as swordtails, size up competitors tailfins before fighting, US scientists show.. Often a male just has to show his big elongated tail, which looks like a pointy sword, to scare off challengers, according to a new study in the latest issue of the journal Animal Behaviour. Yet another study in the same publication concludes that female swordtails prefer male swordtails with big, striped swords. Researchers even think the female fixation on these bright appendages led to their emergence in the first place, since female fondness for novel traits and bright colours appears to have preceded the appearance of male swords. The finding suggests the creation of some secondary sexual characteristics may be influenced, and even controlled, by the opposite sex. For male swordtails, this characteristic is an extension of the tail or caudal fin.. "It is not terribly rigid and cannot be manipulated very efficiently," says Dr Kari Benson, who co-authored the first paper with Dr ...

The hypothesis that skin color is a genetic correlate of IQ was endorsed by Jensen (2006) who suggested that pleiotropy (genes having more than one effect) may underlie the relationship. Skin color became of greater theoretical interest after Ducrest, Keller, and Roulin (2008) reviewed the literature and reported that in 20 wild vertebrate species, darker individuals were more aggressive, sexually active, and resistant to stress than lighter individuals. Studied were three mammal species (African lion, soay sheep, and white-tailed deer), four fish species (mosquito fish, guppy, green swordtail, and Arctic char), four reptile species (asp viper, adder, fence lizard, and spiny lizard), one amphibian species (spadefoot toad) and 36 bird species. Darker individuals also tended to have a larger body mass and greater energy and physical activity such as grooming. Ducrest et al. (2008) confirmed the naturalistic observations using experimental studies such as the administration of melanocortins and the ...
Adult eastern mosquitofish, G. holbrooki (mass = 0.087 ± 0.02 g, mean ± s.d.), were collected from the University of Queensland, St Lucia campus and exposed to a factorial combination of two UVB treatments (low UVB and high UVB) and two temperature treatments (low, 18°C and high, 25°C) such that there were four experimental treatments with 10 replicate tanks in each. Each tank consisted of a 2 l plastic container with 700 ml of aged water (aerated continuously) and 15 fish. Treatment temperatures reflect the maximum and minimum water temperatures recorded 5-10 cm below the water surface at the collection site over a 24 h period, and the thermal range for the infective phase of the whitespot pathogen.. All fish were exposed to a 12 h L : 12 h D light cycle generated by four 40 W full spectrum (UVB, UVA and visible wavelengths) fluorescent tubes (Repti Glo 5.0, Exo Terra, Montreal, Canada; UVB irradiance = 0.23 ± 0.05 W m−2) for 10 h d−1 with an additional pulse of high UV for 2 h in the ...

Some species of fishes exhibit well marked sexual dimorphism. In the Chondrichthyes, the eggs are fertilized within the body of the female and the males are provided with claspers or myxopterygia for transferring the sperms into the body of the female. Among teleosts, an intromittent copulatory organ is present only in those species like Mystus seenghala in which a conical genital papilla is present and fertilization is external. In Cyprinodonts (e.g. Gambusia) the vas deferens is produced into a tube upto the end to the interior rays of the anal fin. In the Poecillidae also the males are provided with complicated intromittent organ developed from modified anal fin rays, ending in curved hooks, spines and barbs. The male four-eyed fish, Anableps, is also provided with a special tube for copulation. In all these fishes, the fertilized ova are retained within the body of the female and young ones are born.. In several species of fishes, the sexual differences are not related with copulation ...
October 25, 2017 Health Care, Heart Care Foundation of India, Medicine Comments Off Mosquito Menace: How to win over our collective failure Napoleon Hill once said that "Most great people have attained their greatest success just one step beyond their greatest failure." Its time for all of us to convert our biggest failure, to control mosquito menace, into success. Today dengue is in alarming condition in Kerala, West Bengal, Karnataka and a mysterious illness in Indore (? Zika ? Alpha Virus) with arthritis. We all must agree that collectively we have failed in controlling the mosquito menace. Any mosquito container index above 5% requires community integrated cluster approach for mosquito density reduction together with effective anti-larval measures. Mosquito repellent impregnated mosquito nets are not available to patients. Anti-larval measures such as temephos (an organophosphate larvicide) and mosquito fish or Gambusia (a freshwater fish) also are not available to a common man. Then what is ...
Dorsal spines (total): 0; Dorsal soft rays (total): 16-17; Anal spines: 0; Anal soft rays: 17 - 18; Vertebrae: 31 - 32. Diagnosis: Males of Nothobranchius seegersi share with the other members of the Nothobranchius neumanni species group a combination of colouration characters, which distinguish them from all other species of the genus: caudal fin red or partially red; pectoral fin hyaline; anal fin yellow with red stripes, proximal portion light bluish grey (Ref. 87047). It is distinguihed from N. neumanni by bright light blue scales, vs. pale bluish grey; an irregular pattern formed by red scale margins on lateral body and head vs. uniform; and a single, blue male colour morph, vs. two colour morphs, blue and red; both male and female of N. seegersi have a relatively higher predorsal length compared to N. neumanni, 60.3-68.8 vs. 54.8-61.0% of standard length in males, 68.0-68.4 vs. 57.1-64.6% of standard length in females (Ref. 87047). Based on osteological characters, Nothobranchius seegersi ...
This is the last post for Sex Week]. The animal kingdom is filled with wild extravagances, and a lot of them have something to do with sex. Hermit Fiddler crabs wave their claws, swordtail fish flash their swordtails, manakins leap and buzz their wings. Darwin considered these displays so important and so puzzling ("the sight of a feather in a peacocks tail, whenever I gaze at it, makes me feel sick!" he wrote to a colleague), that he dedicated half of a book to the subject.. Darwin argued that many extravagant displays in male animals were the result of a special kind of evolution he called sexual selection. Females preferred males with certain traits over other males, and so those males had more offspring, which inherited their traits. In recent decades, scientists have documented many cases in which females do indeed prefer males with certain traits over others. As I mentioned in my post on electric fish, for example, female bulldog fishes are more attracted to long electric pulses than ...
I read of an experiment, once, in which researchers took a fish species, a close relative (at least on evolutionary terms; I dont know how a baraminologist would view the matter) of swordtail fish, but with no spine sticking out of its tail fin. Now, they knew from research with swordtails that the tail spines made males attractive to females. By grafting fake spines into the tails of males of this normally swordless species, they found that females of this species, also were attracted to males with tail spines. It is perfectly possible to have a built-in reaction to a trait that ones species does not normally have -- which would give natural selection something to work with if a random mutation produced that trait. Presumably birds could in many cases have such already existing quirks that could make some mutation affecting coloration advantageous ...

SIZE matters. Well-endowed male mosquito fish tend to be more successful at mating. But females may evolve bigger brains to help them escape overeager mates with these longer organs.. Mating between mosquito fish - a relative of the guppy - is far from romantic. The male makes no effort to court partners. Instead, he sneaks up and attempts to copulate by force up to 1000 times a day - and females try to avoid the harassment. Males use a modified anal fin, the gonopodium, to deliver sperm into the female.. Séverine Buechel at Stockholm University in Sweden and colleagues bred males to have longer gonopodia, and found that this led to bigger-brained females (Proceedings of the Royal Society B, doi.org/bvmv).. Harassment by males poses many risks for females: injury, disease transmission and lower survival rates for offspring, for example. Having a larger brain might help females see better or pay more attention to their surroundings, making it easier for them to spot males and get away.. ...

Limahuli Garden and Preserve.. CONCLUSIONS AND SUGGESTIONS TO MINIMIZE DEVELOPMENT IMPACT. Keep the fish population native. The fish population in the stream is entirely native and serious consideration should be given towards maintaining this now rare condition in Hawaii. The urge to stock the stream with poeciliids (i.e. mosquitofish, swordtail, mexican molly) to control mosquitoes should be resisted strongly. These alien species compete with the native `o`opus for food and living space and they are the more hardy, meaning, they will have a detrimental impact. The Hawaii Cooperative Fishery Research Unit has published information on this subject (Hathaway 1980, Norton, et al. 1978).. Visitors in the valley who are allergic to mosquito bites may be provided with mosquito repellent sprays. The historical introduction of these poeciliids to control the mosquitoes has obviously not worked.. Based on casual conversations with freshwater fishing enthusiasts, it appears that the spread of smallmouth ...

Please help me to diagnose my Goldfishs malady 1/31/09 In reading others problems on your site, I am wondering if my fish has more than one issue simultaneously. Meatball has been in a 450 gallon pond in our backyard for 5 years. She was originally one of a half dozen feeders we purchased from our LFS to establish the pond. She has 17 other pond mates, not including mosquito fish, which consist of: the rest of the original 6 feeders, 4 shubunkin and the remainders are koi. The pond has a bio-filter for up to 750 gallon ponds, a waterfall, a fountain and a UV light spitter frog. We live in Southern California (5 miles from Disneyland) so I feed the pond pets year-round, but in the Fall/Winter they are fed a lower protein food. Tuesday we moved her into a Marineland 25 gallon tall with an Eclipse II filtration and bio filter system that is in our office and have been treating her w/ Melafix for three days. She is the size of a softball. ,I see this... a goldfish with a dropsical condition... ...
These remarkable eyes belong to a male St. Marks fly Bibio marci - which has not one pair of compound eyes, but two. This is the black fly that dances just above the grass on spring days, dangling its long hind legs. You can find a picture of this behaviour on Nyctaluss Stand and Stare blog. These dancing males are on the lookout for females, which they approach from below, and the conjecture is that those long, fine hairs in between each individual compound eye lens (ommatidium) somehow help in the flys detection of movement above and precise positioning when he grabs a female. ...

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 ...
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 ...

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 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

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.. ...

In other species: Panuco swordtail , Perugias limia Mendelian trait/disorder: yes Mode of inheritance: Autosomal Considered a defect: no Key variant known: yes Year key variant first reported: 2015 Species-specific description: Lank et al. (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 ...

Why was my Wheel stuck? Wasnt I doing everything right? I was organized, I was working hard. I was showing up for my friends and husband when they needed me. Where was the problem? What part of my life was stuck?. I pulled a few clarifying cards, one of which was the 10 of Swords.. According to these cards, my personal resources were tapped out.. Another card I received was the 3 of Pentacles, in which two people are approaching a Master Builder with plans. They need something of him. Was this indicative of what others have needed from me? Or was this indicative of expectations Id set for myself? Another card I received was the 3 of Cups Reversed, which suggested a lack of satisfaction. Were others unsatisfied with my presence or the work I was producing? Or was I unsatisfied with things because of my stuck wheel?. I also pulled the 4 of Swords shows a person resting, possibly dead.

That there was a custom in Saxon times to fix a touch stone to the sword. These were often unusual shaped or coloured stones, often with a natural hole in them. A lace would secure this stone to the scabbard or hilt of the sword. The thought was that the stone would draw the poison out of any wound inflicted by the blade. If you cut yourself sharpening, you had ready access to the stone. An enemy would most certainly not. So even a superficial cut would fester and perhaps even kill your enemy after the fact ...

With great number of grapevine (Vitis vinifera L.) varietes, ever increasing attention today is given to possibility of growing interspecies hybrids varietes with resistance on fungal diseases and abiotic stresses. Interspecies hybrid varietes are created by crossing with varietes of European grapevine (Vitis vinifera L.) and some other species of Vitis genus. Interspecies hybrids are often associated with presence of some unwanted aromas (e.g. foxy and strawberry-like aromas) that have originated from the oldest generations of interspecific hybrid varietes. Thats why when these varietes aromatic profile is evaluated it is of great importance whether are unwanted aromas present. Research was done on 11 varietes. Analysed varietes belong to group of interspecies hybrids that were created in breeding programms in Hungary, Germany and Serbia: „Bačka", „Bianca", „Johanniter", „Kozmopolita", „Lisa", „Merzling", „Orion", „Phoenix", „Sirius", „Solaris" i „Staufer".

Aphanomyces were initially known as parasites of plants, small invertebrates and crustaceans. Probably the first case reported of fish being infected by Aphanomyces species was from guppy (Poecilia reticulata), Maxican blind cave (Astyanax mexicanus), a hybrid of platy (Platypoecilus maculatus) and swordtail (Xiphophorus hellerii) [26]. Aphanomyces, along with other oomycetes, e.g. Saprolegnia species have caused severe losses to aquaculture industry till to-date. From an evolutionary point of view it seems that the pathogenesis of plant oomycetes is mediated by effectors, while host invasion by animal pathogenic oomycetes is facilitated by expansion of proteases [24]. Many infectious microorganisms require proteases for replication or use proteases as virulence factors to cross proteinaceous barrier within the host. Proteases secreted by the fish oomycete Saprolegnia parasitica are suggested to be involved in attacking the host tissue and paving the way for further penetration of the fungus ...
The saltwater mosquito, Aedes vigilax, is prolific in coastal wetlands including mangroves and saltmarshes. Ae. vigilax is a vector for arboviruses such as Ross River and Barmah Forest viruses, with significant consequences for human health and economic productivity. In Australia the dominant form of mosquito control is chemicals. For mangroves, this is because there is a critical lack of knowledge supporting alternative approaches, such as environmental modification or biological control using larvivorous fish. This review examines the potential of fish as biological agents for the control of mosquito larvae in mangroves. We consider two key aspects: how larvivorous fish use mangroves; and can larvivorous fish reduce larval mosquito populations sufficiently to provide effective mosquito control? The link between fish and mangroves is reasonably well established, where mangroves act as refuge habitat for small and juvenile fish. Also, research has established that fish can be significant ...
TY - JOUR. T1 - Basic fibroblast growth factor and ultraviolet B transform melanocytes in human skin. AU - Berking, Carola. AU - Takemoto, Richelle. AU - Satyamoorthy, Kapaettu. AU - Elenitsas, Rosalie. AU - Herlyn, Meenhard. PY - 2001. Y1 - 2001. N2 - Ultraviolet (UV) light is an epidemiological risk factor for melanoma, but its specific contribution to melanoma induction is not known. The first critical step of melanoma development, ie, the uncontrolled proliferation of melanocytes, may be induced by a combination of UV damage and an imbalance of growth factor production by cells in the immediate area of the melanocyte. Among several candidates, basic fibroblast growth factor (bFGF) is the major autocrine growth factor in melanoma and associated with tumor progression. Overexpression of bFGF via adenoviral gene transfer in human skin xenografted to severe combined immunodeficiency mice led to black-pigmented macules within 3 weeks of treatment. Immunofluorescence analysis demonstrated ...
Seahorses compose the fish genus Hippocampus within the family Syngnathidae, in order Syngnathiformes. Syngnathidae also includes the pipefishes. Hippocampus comes from the Ancient Greek hippos meaning horse and kampos meaning sea monster .. There are about 40 species of seahorse. They are mainly found in shallow tropical and temperate waters throughout the world. They prefer to live in sheltered areas such as seagrass beds, coral reefs, or mangroves. Colonies have been found in European waters such as the Thames Estuary. From North America down to South America there are approximately four species, ranging from the very small (dwarf seahorses are only about 2.5 centimeters (1 in) to much larger specimens off the Pacific Coast of Central America (the foot-long H. ingens). H. erectus are larger seahorses that range from Nova Scotia to around Uruguay. Three species live in the Mediterranean Sea: H. hippocampus (long snout), H. brevirostris (short snout) and H. fuscus (immigrated from the Red ...
