Sexual selection plays several intricate and complex roles in the related processes of local
adaptation and speciation. In some cases sexual selection can promote these processes …

Sexual selection has resulted in some of the most captivating features of insects, including
flashy colors, bizarre structures, and complex pheromones. These features evolve in …

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 …

Many studies have recorded phenotypic changes in natural populations and attributed them
to climate change. However, controversy and uncertainty has arisen around three levels of …

The scientific study of networks-computer, social, and biological-has received an enormous
amount of interest in recent years. However, the network approach has been applied to the …

At a glance, most species seem adapted to the environment in which they live. Yet species
relentlessly evolve, and populations within species evolve in different ways. Evolution, as it …

There are now thousands of estimates of phenotypic selection in natural populations,
resulting in multiple synthetic reviews of these data. Here we consider several major lessons …

Local adaptation, adaptive population divergence and speciation are often expected to
result from populations evolving in response to spatial variation in selection. Yet, we lack a …

Studies of phenotypic selection document directional selection in many natural populations.
What factors reduce total directional selection and the cumulative evolutionary responses to …

Rapid climate change both imposes strong selective pressures on natural populations–
potentially reducing their growth rate and causing genetic evolution–and affects the …
