Female mate-choice copying in guppies, Poecilia reticulata: a re-evaluation
It has been argued that intraspecific mate-choice copying can be adaptive under certain conditions. Dugatkin's (1992, Am. Nat.139, 1384-1389) work with guppies, Poecilia reticulataremains the most influential experimental demonstration of this phenomenon. We replicated Dugatkin's work using several choice criteria to ensure that our results were not dependent upon any single method of judging m...
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 کاملEvidence 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 کاملAerial Jumping in the Trinidadian Guppy (Poecilia reticulata)
Many fishes are able to jump out of the water and launch themselves into the air. Such behavior has been connected with prey capture, migration and predator avoidance. We found that jumping behavior of the guppy Poecilia reticulata is not associated with any of the above. The fish jump spontaneously, without being triggered by overt sensory cues, is not migratory and does not attempt to capture...
