As biodiversity decreases worldwide, the development of effective techniques to track
changes in ecological communities becomes an urgent challenge. Together with other …

The process of adaptive radiation—the proliferation of species from a single ancestor and
diversification into many ecologically different forms—has been of great interest to …

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 …

Behavioral interference between species, such as territorial aggression, courtship, and
mating, is widespread in animals. While aggressive and reproductive forms of interspecific …

Interactions between species can promote evolutionary divergence of ecological traits and
social signals,, a process widely assumed to generate species differences in adaptive …

Twenty years ago, a seminal paper summarized the role of sexual selection in speciation as
the coordinated evolution of (male) courtship signals and (female) preferences leading to …

Ecological character displacement (ECD), the evolutionary divergence of competing
species, has oscillated wildly in scientific opinion. Initially thought to play a central role in …

Direct interactions among conspecific and heterospecific animals are often mediated by
aggressive behavior. We analyze the ecology and evolution of resource-related …

Free‐ranging domestic dogs are the world's most common carnivore and can negatively
interact with native wildlife at multiple levels. Yet the intraguild competitive effects of dogs on …

Visual signals are shaped by variation in the signaling environment through a process
termed sensory drive, sometimes leading to speciation. However, the evidence for sensory …
