Rapid evolution of escape ability in Trinidadian guppies (Poecilia reticulata).
Predators are widely assumed to create selection that shapes the evolution of prey escape abilities. However, this assumption is difficult to test directly due to the challenge of recording both predation and its evolutionary consequences in the wild. We examined these events by studying natural and experimental populations of Trinidadian guppies, Poecilia reticulata, which occur in distinct hi...
متن کاملSystemic Granulomatosis in Guppies Poecilia reticulata
In many guppy Poecilia reticulata farms in the vicinity of Bangkok, diseases have caused longlasting fish death and consequently large cumulative mortality. Diseased guppies were collected and subjected to histopathological analysis. The analysis revealed systemic granulomatosis as a remarkable histological sign. Rod-shaped bacterial cells with strong acid-fastness were found in the granulomas....
متن کاملLocal adaptation and the evolution of phenotypic plasticity in Trinidadian guppies (Poecilia reticulata).
Divergent selection pressures across environments can result in phenotypic differentiation that is due to local adaptation, phenotypic plasticity, or both. Trinidadian guppies exhibit local adaptation to the presence or absence of predators, but the degree to which predator-induced plasticity contributes to population differentiation is less clear. We conducted common garden experiments on gupp...
متن کاملFamiliarity 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 کاملObservational Learning and Predator Inspection in Guppies (Poecilia reticulata)
Prior work has demonstrated that, following a predator inspection visit of their own, guppies prefer to associate with individuals who inspected a predator most closely. Based on this work, as well as studies of social learning in the context of mate choice, we predicted that male guppies that observed but did not participate in an inspection trial would subsequently choose to associate with th...
