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 …

We explore how integrating behavioural ecology and macroecology can provide fundamental
new insight into both fields, with particular relevance for understanding ecological …

Interspecific territoriality occurs when individuals of different species fight over space, and
may arise spontaneously when populations of closely related territorial species first come into …

Costly interactions between species that arise as a by-product of ancestral similarities in
communication signals are expected to persist only under specific evolutionary circumstances. …

Interspecific territoriality may play an important role in structuring ecological communities,
but the causes of this widespread form of interference competition remain poorly understood. …

Competition between closely related species has long been viewed as a powerful selective
force that drives trait diversification, thereby generating phenotypic diversity over …

Much ecological and evolutionary theory predicts that interspecific interactions often drive
phenotypic diversification and that species phenotypes in turn influence species interactions. …

Field investigations of phenotypic variation in free‐living organisms are often limited in scope
owing to time and funding constraints. By collaborating with online communities of amateur …

Animals often view humans as predators, leading to alterations in their behavior. Even
nuanced aspects of human activity like clothing color affect animal behavior, but we lack an …
