Adaptive versus non‐adaptive phenotypic plasticity and the potential for contemporary adaptation in new environments
TLDR
It is concluded that adaptive plasticity that places populations close enough to a new phenotypic optimum for directional selection to act is the only Plasticity that predictably enhances fitness and is most likely to facilitate adaptive evolution on ecological time-scales in new environments.
Costs of reproduction: an evaluation of the empirical evidence
TLDR
It is argued that a relevant empirical study must deal with genetically based tradeoffs, and only the last two methods properly address the "costs" dealt with by theoreticians.
Evaluation of the Rate of Evolution in Natural Populations of Guppies (Poecilia reticulata)
TLDR
The resulting rate of evolution of age and size at maturity was similar to rates typically obtained for traits subjected to artificial selection in laboratory settings and up to seven orders of magnitude greater than rates inferred from the paleontological record.
THE IMPACT OF PREDATION ON LIFE HISTORY EVOLUTION IN TRINIDADIAN GUPPIES (POECILIA RETICULATA)
TLDR
Empirical studies have sought correlations between life histories and potential sources of demographic selection and, in some cases, have attempted to determine if the organisms have evolved as predicted by theory, but few have achieved either goal.
Do faster starts increase the probability of evading predators
TLDR
The results support the assumption that faster starts increase the probability of successfully evading a predation strike and measure the effect of acceleration ability on evasion outcome in Guppies evading the strike of a natural predator.
Life‐History Evolution in Guppies. VII. The Comparative Ecology of High‐ and Low‐Predation Environments
TLDR
It is concluded that guppies from high‐predation environments experience higher levels of resource availability in part because of correlated differences in the environment and in part as an indirect consequence of predation.
Local adaptation in Trinidadian guppies alters ecosystem processes
TLDR
It is demonstrated that populations of Trinidadian guppies (Poecilia reticulata), characterized by differences in phenotypic and population-level traits, differ in their impact on ecosystem properties and demonstrates that evolution can significantly affect both ecosystem structure and function.
Ecology and Evolution of Swimming Performance in Fishes : Predicting Evolution with Biomechanics
TLDR
Here, some of the major ecological factors that might have shaped the evolution of locomotor performance in fishes are investigated using an integrative approach.
Effect of extrinsic mortality on the evolution of senescence in guppies
TLDR
It is reported here that guppies derived from natural populations do not have an earlier onset of senescence with respect to either mortality or reproduction but do withrespect to swimming performance, which assesses neuromuscular function.
The population ecology of contemporary adaptations: what empirical studies reveal about the conditions that promote adaptive evolution
TLDR
It is suggested that opportunities for population growth may be a key factor that promotes rapid evolution, since directional selection might otherwise be expected to cause population decline and create the potential for local extinction, which is an ever-present alternative to local adaptation.
