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 کاملParasite Transmission in Social Interacting Hosts: Monogenean Epidemics in Guppies
BACKGROUND Infection incidence increases with the average number of contacts between susceptible and infected individuals. Contact rates are normally assumed to increase linearly with host density. However, social species seek out each other at low density and saturate their contact rates at high densities. Although predicting epidemic behaviour requires knowing how contact rates scale with hos...

What are guppies? Guppies (Poecilia reticulata) are small tropical fish, native to the coastal streams of northeast South America. They owe their name to Robert John Lechmere Guppy who introduced them into the aquarium trade. Guppies have since become very popular aquarium fish, known for colorful males and live-bearing females. But guppies are also one of the premier model systems for the stud...
متن کاملFamiliarity for associations? A test of the domain dichotomy theory.
Episodic recognition memory is mediated by functionally separable retrieval processes, notably familiarity (a general sense of prior exposure) and recollection (the retrieval of contextual details), whose relative engagement depends partly on the nature of the information being retrieved. Currently, the specific contribution of familiarity to associative recognition memory (where retrieval of t...
متن کاملSocial familiarity modulates personality trait in a cichlid fish.
Personality traits, such as exploration-avoidance, are expected to be adaptive in a given context (e.g. low-risk environment) but to be maladaptive in others (e.g. high-risk environment). Therefore, it is expected that personality traits are flexible and respond to environmental fluctuations, given that consistency across different contexts is maintained, so that the relative individual respons...
