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

BACKGROUND The interdisciplinary field of animal coloration is growing rapidly, spanning
questions about the diverse ways that animals use pigments and structures to generate …

Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

Animal coloration is one of the most conspicuous aspects of human-perceived organismal
diversity, yet also one of the least understood. In particular, explaining why species have …

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 …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

The 'social complexity hypothesis' for communication posits that groups with complex social
systems require more complex communicative systems to regulate interactions and relations …

Acoustic signals mediate mate choice, resource defense, and species recognition in a broad
range of taxa. It has been proposed, therefore, that divergence in acoustic signals plays a …

Natural selection commonly drives the origin of species, as Darwin initially claimed.
Mechanisms of speciation by selection fall into two broad categories: ecological and …

Visual opsin genes expressed in the rod and cone photoreceptor cells of the retina are core
components of the visual sensory system of vertebrates. Here, we provide an overview of the …
