Plasticity-led evolution is central to evolutionary theory. Although challenging to study in
nature, this process may be particularly apparent in novel environments such as cities. We …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Speciation, that is, the evolution of reproductive barriers eventually leading to complete
isolation, is a crucial process generating biodiversity. Recent work has contributed much to …

Habitat fragmentation, an important element of current global change, has profound
repercussions on population and species extinction. Landscape fragmentation reduces …

It can be challenging for organisms to achieve a good match between their phenotypic
characteristics and environmental requirements that vary in space and time. The evolution of …

Background Microhabitat changes are thought to be among the main drivers of
diversification. However, this conclusion is mostly based on studies on vertebrates. Here, we …

Matching habitat choice is a unique, flexible form of habitat choice based on self-
assessment of local performance. This mechanism is thought to play an important role in …

Evolutionary theory has made large impacts on our understanding and management of the
world, in part because it has been able to incorporate new data and new insights …

Organisms commonly experience significant spatiotemporal variation in their environments.
In response to such heterogeneity, different mechanisms may act that enhance ecological …

Natural selection results in adaptation for populations, not individuals. Yet environmental
change can reduce the expected fitness of an individual. Selection will favor the evolution of …
