Evidence for Mate Choice by Male Guppies (Poecilia reticulata)
1985). Female body size is positively correlated both Mate choice by males in organisms that do not make obviously costly contributions to offspring should be expected where sperm production is limited and courtship time is finite. Although male guppies (Poecilia reticulata) contribute only sperm to their offspring, preliminary evidence points to male mate choice in this species. Thus, the hypo...
متن کاملConcurrent effects of sperm competition and female quality on male mate choice in the Trinidadian guppy (Poecilia reticulata)
Males are generally expected to be discriminating in their choice of mates when females vary in quality and when under sperm competition from rival males. However, how sperm competition and female quality interact to influence male mating decisions remains poorly understood. Here, we explored the concurrent effects of sperm competition and female body length on male mating decisions in the Trin...
متن کاملSocial networks in the guppy (Poecilia reticulata).
Social network theory is used to elicit details of the social structure of a population of free-ranging guppies, Poecilia reticulata. They were found to have a complex and highly structured social network, which exhibited characteristics consistent with the 'small world' phenomenon. Stable partner associations between individuals were observed, a finding that fulfils the basic prerequisite for ...
متن کاملMale guppies (Poecilia reticulata) adjust their mate choice behaviour to the presence of an audience
In recent years analyzing animal behaviour in light of the social environment has become widely accepted. Especially many mating interactions do not happen in privacy, but in a public arena, raising the question of how this affects the behaviour of both the focal individual and the observing audience individual. We studied in feral guppies whether male preferences for female body size, a correl...
متن کاملEffect of Competition of Mate Choice in Male Guppies Poecilia reticulata
Mate choice behavior reflects the likelihood of an individual choosing to mate with a particular individual and not another. In the guppy, Poecillia reticulata, mate choice studies have revealed that males have a preference for large females. In this study we assessed if mate choice in male guppies was affected by competition from other males. We predicted that males would court smaller females...
