Adaptations of post‐hatching animals have attracted far more study than have embryonic
responses to environmental challenges, but recent research suggests that we have …

Cannibalism, once viewed as a rare or aberrant behavior, is now recognized to be
widespread and to contribute broadly to the self‐regulation of many populations …

Biotic conflict can create evolutionary arms races, in which innovation in one group
increases selective pressure on another, such that organisms must constantly adapt to …

Developmental plasticity is the ability of a genotype to express multiple phenotypes under
different environmental conditions and has been shown to facilitate the evolution of novel …

In response to novel environments, invasive populations often evolve rapidly. Standing
genetic variation is an important predictor of evolutionary response but epigenetic variation …

Life-history theory suggests that organisms must distribute a limited share of their energetic
resources among competing life-history trait demands. Therefore, the trade-off strategies …

Abstract Weakfish Cynoscion regalis (Bloch and Schneider, 1801) is one of the most recent
invasive fish in the Iberian Peninsula (Europe). Weakfish has established in the Sado …

Temperature affects the rate of biochemical and physiological processes in amphibians,
influencing metamorphic traits. Temperature patterns, as those observed in latitudinal and …

Predation reduces the population density of prey, affecting its fitness and population
dynamics. Few studies have connected trait changes with fitness consequences in prey and …

Natural populations can show rapid adaptive responses to intense (human-mediated)
environmental change. The potential for exploiting rapidly evolved traits for conservation …
