Inter- and Intra-individual Variation in Predator-related Behavioral Plasticity Expressed by Female Green Swordtails (<i>Xiphophorus hellerii</i>)
Phenotypic plasticity is the ability of a genotype to express different phenotypes, under different environmental conditions. Behavioral plasticity is a type of phenotypic plasticity in which a change in phenotype can rapidly occur. Though often studied at the level of the population, behavioral plasticity studies at the level of the individual could provide insight into how plasticity evolves ...
متن کاملAn Indirect Cue of Predation Risk Counteracts Female Preference for Conspecifics in a Naturally Hybridizing Fish Xiphophorus birchmanni
Mate choice is context dependent, but the importance of current context to interspecific mating and hybridization is largely unexplored. An important influence on mate choice is predation risk. We investigated how variation in an indirect cue of predation risk, distance to shelter, influences mate choice in the swordtail Xiphophorus birchmanni, a species which sometimes hybridizes with X. malin...
متن کاملGenetic variation and phylogeography of the swordtail fish Xiphophorus cortezi (Cyprinodontiformes, Poeciliidae).
Swordtail fish have been studied extensively in relation to diverse aspects of biology; however, little attention has been paid to the patterns of genetic variation within and among populations of swordtails. In this study, we sequenced the mtDNA control region from 65 individuals and 10 populations of Xiphophorus cortezi to investigate the genetic variation within and among populations, includ...
متن کاملA polymorphism in female preference for a polymorphic male trait in the swordtail fish Xiphophorus cortezi
Xiphophorus cortezi males are polymorphic for the pigment pattern vertical bars. In this study, we determined whether X. cortezi females are polymorphic in their preference for this trait by examining both withinand between-individual variation in female preference. There was significantly more variation in female preference within than between individuals using both video animations and live m...
متن کاملFemale disdain for swords in a swordtail fish.
Studies of mate choice evolution tend to focus on how female mating preferences are acquired and how they select for greater elaboration of male traits. By contrast, far less is known about how female preferences might be lost or reversed. In swordtail fish Xiphophorus, female preference for the sword ornament is an ancestral trait. Xiphophorus birchmanni, however, is one species that has secon...
