Ecological character displacement, mostly seen as increased differences of size in sympatry
between closely‐related or similar species, is a focal hypothesis assuming that species too …

The extent to which interspecific interference competition has contributed to character
evolution is one of the most neglected problems in evolutionary biology. When formerly …

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 …

A definitive guide to the depth and breadth of the ecological sciences, revised and updated
The revised and updated fifth edition of Ecology: From Individuals to Ecosystems–now in full …

This book provides an introductory text in ecology aimed at undergraduate students and is
divided into sections entitled: introduction; conditions and resources; individuals …

Speciation can be viewed as a continuum, potentially divisible into several states:(1)
continuous variation within panmictic populations,(2) partially discontinuous variation with …

In The Origin of Species, Darwin proposed his principle of divergence of character (a
process now termed “character displacement”) to explain how new species arise and why …

Mechanisms of speciation are not well understood, despite decades of study. Recent work
has focused on how natural and sexual selection cause sexual isolation. Here, we …

Competition has always been a cornerstone of evolutionary biology, and aggression is the
predominant form of direct competition in animals, but the evolutionary effects of aggression …

Understanding the role of competition in explaining phenotypic diversity is a challenging
problem, given that the most divergent species may no longer compete today. However …
