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 کاملPredicting the direction of ornament evolution in Trinidadian guppies (Poecilia reticulata).
Sexual selection is thought to be opposed by natural selection such that ornamental traits express a balance between these two antagonistic influences. Phenotypic variation among populations may indicate local shifts in this balance, or that different stable 'solutions' are possible, but testing these alternatives presents a major challenge. In the guppy (Poecilia reticulata), a small freshwate...
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 کاملBehavioral types as predictors of survival in Trinidadian guppies (Poecilia reticulata)
Studies of the fitness consequences of behavioral types often focus on isolated behaviors and ignore potential across-context correlations that may affect fitness. This approach leads to heterogeneous results across studies because correlations themselves may be adaptive in populations under significant predation pressure. We quantified suites of behaviors in 4 different contexts and identified...
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....
