The range of resources that a species uses (ie its niche breadth) might determine the
geographical area it can occupy, but consensus on whether a niche breadth–range size …

Niche breadth is a unifying concept spanning diverse aspects of ecology, evolution, and
conservation biology. Niche breadth usually refers to the diversity of resources used or …

How ecological niche breadth evolves is central to adaptation and speciation and has been
a topic of perennial interest. Niche breadth evolution research has occurred within …

A long-standing theory, originating with Darwin, suggests that abiotic forces set species
range limits at high latitude, high elevation, and other abiotically 'stressful'areas, while …

Over the past decade, advances in both molecular developmental biology and evolutionary
ecology have made possible a new understanding of organisms as dynamic systems …

Geographic range size has long fascinated ecologists and evolutionary biologists, yet our
understanding of the factors that cause variation in range size among species and across …

The nature and timing of evolution of niche differentiation among closely related species
remains an important question in ecology and evolution. The American live oak clade …

The geographic ranges of closely related species can vary dramatically, yet we do not fully
grasp the mechanisms underlying such variation. The niche breadth hypothesis posits that …

The ecological niche can be thought of as a volume in multidimensional space, where each
dimension describes an abiotic condition or biotic resource required by a species. The …

Functional trait‐based approaches have seen rapid development in community ecology and
biogeography in recent years, as they promise to offer a better mechanistic and predictive …
