Familiarity affects collective motion in shoals of guppies (Poecilia reticulata)
The coordinated and synchronized movement of animals in groups often referred to as collective motion emerges through the interactions between individual animals within the group. Factors which affect these interactions have the potential to shape collective movement. One such factor is familiarity, or the tendency to bias behaviour towards individuals as a result of social recognition. We exam...
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 کاملThe effects of familiarity on escape responses in the Trinidadian guppy (Poecilia reticulata)
Predation is the main cause of mortality during early life stages. The ability to avoid and evade potential threats is, therefore, favoured to evolve during the early stages of life. It is also during these early stages that the process of familiarization occurs. It has long been recognized that associating with familiar individuals confers antipredator benefits. Yet gaps in our knowledge remai...
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...
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...
