Biological invasions are 'natural'experiments that can improve our understanding of
contemporary evolution. We evaluate evidence for population differentiation, natural …

To achieve a coherent evolutionary theory, it is necessary to account for the effects of the
environment on the process of development. Phenotypic plasticity is the change in the …

Biological responses to climate change have been widely documented across taxa and
regions, but it remains unclear whether species are maintaining a good match between …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Urban ecosystems are rapidly expanding throughout the world, but how urban growth affects
the evolutionary ecology of species living in urban areas remains largely unknown. Urban …

Over the past decade, advances in both molecular developmental biology and evolutionary
ecology have made possible a new understanding of organisms as dynamic systems …

Adaptation to climate, evolving over contemporary time scales, could facilitate rapid range
expansion across environmental gradients. Here, we examine local adaptation along a …

Although secondary metabolites are recognized as fundamental to the defence of plants
against insect and mammalian herbivores, their relative importance compared to other …

Floral traits are hypothesized to evolve primarily in response to selection by pollinators.
However, selection can also be mediated by other environmental factors. To understand the …

Estimating the genetic basis of quantitative traits can be tricky for wild populations in natural
environments, as environmental variation frequently obscures the underlying evolutionary …
