The global impacts of climate change are evident in every marine ecosystem. On coral reefs,
mass coral bleaching and mortality have emerged as ubiquitous responses to ocean …

In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

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 …

Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

The interactions between organisms and their environments can shape distributions of
spatial genetic variation, resulting in patterns of isolation by environment (IBE) in which …

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Gene flow among populations can enhance local adaptation if it introduces new genetic
variants available for selection, but strong gene flow can also stall adaptation by swamping …

Climate change is leading to shifts in species geographical distributions, but populations are
also probably adapting to environmental change at different rates across their range. Owing …

Pollen-pistil interactions establish interspecific/intergeneric pre-zygotic hybridization barriers
in plants. The rejection of undesired pollen at the stigma is crucial to avoid outcrossing but …
