Social 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 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 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 کاملAge and experience affect female choice in the guppy (Poecilia reticulata).
Female choices of males, and how these choices are influenced by ecological and social factors, have been studied extensively. However, little is known about the effects of age and breeding experience on female mating decisions. We used video techniques to examine female mate choice in guppies based on the area of carotenoid (orange) pigmentation on the body. Females were presented with paired ...
متن کاملAvoidance Learning and "Personality" in the Guppy (Poecilia reticulata)
The authors examined the relationships between 2 "personality" dimensions (Approach and Fear Avoidance) and 2-way active avoidance learning performance in the guppy (Poecilia reticulata). Contrary to expectations (based on prior rodent studies), higher fearfulness facilitated both earlier appearance and acquisition of the shuttlebox avoidance responses, especially in the less exploratory and ac...
