Eugenol Como Anestésico Para Labores De Manipulación De Xiphophorus Helleri (heckel, 1848) (cyprinodontiformes: Poecilidae) Eugenol as Anesthetic for Handling Tasks of Xiphophorus Helleri (heckel, 1848) (cyprinodontiformes: Poecilidae)
The aim of this study was to perform various tests of the anesthetic efficacy of eugenol applied to different handling tasks such as artificial insemination, spawning induction, obtaining body weight and length, the conduct of operations, biopsies and transport of Xiphophorus helleri (Heckel, 1848). The tests were performed on 10 individual males and 10 individual females of X. helleri -1 (swor...
متن کاملInter- 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 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...
