A Transcriptome Derived Female-Specific Marker from the Invasive Western Mosquitofish (Gambusia affinis)
Sex-specific markers are a prerequisite for understanding reproductive biology, genetic factors involved in sex differences, mechanisms of sex determination, and ultimately the evolution of sex chromosomes. The Western mosquitofish, Gambusia affinis, may be considered a model species for sex-chromosome evolution, as it displays female heterogamety (ZW/ZZ), and is also ecologically interesting a...
متن کاملFemale fitness declines with increasing female density but not male harassment in the western mosquitofish, Gambusia affinis
Sexual conflict occurs when individuals of one sex express traits that reduce the fitness of individuals of the other sex. In many poeciliid fish, males harass females for copulations, which is thought to reduce female fitness by lowering foraging efficiency and increasing predation risk, energetic expenditure and the likelihood of disease transmission. Mating may also be costly for males, who ...
متن کاملUse of microsatellite paternity analysis to determine male mating success in the western mosquitofish, Gambusia affinis
I tested the effects of male body size on male mating behavior and reproductive success in the western mosquitofish, Gambusia affinis. In two separate behavioral experiments (male–male competition and no-competition), I tested the predictions that (1) larger males out-compete smaller males for mates and (2) small males increase their number of mating attempts in the absence of a larger competit...
متن کاملPersonality traits and dispersal tendency in the invasive mosquitofish (Gambusia affinis).
Ecological invasions, where non-native species spread to new areas, grow to high densities and have large, negative impacts on ecological communities, are a major worldwide problem. Recent studies suggest that one of the key mechanisms influencing invasion dynamics is personality-dependent dispersal: the tendency for dispersers to have a different personality type than the average from a source...
متن کاملAcute toxicity of mosquitocidal compounds to young mosquitofish, Gambusia affinis.
Toxicity of Florida mosquito larvicides and adulticides to 3-5 day old Gambusia affinis was determined in the laboratory. After 24-h exposure, the larvicides, temephos, fenoxycarb and petroleum distillates had LC50 values of 5.60, 1.05 and 593.4 ppm, respectively. After 24 h the adulticides resmethrin, fenthion, naled and malathion had LC50 values of 0.007, 2.94, 3.50 and 12.68 ppm, respectivel...
