Conservationists are increasingly using autonomous acoustic recorders to determine the
presence/absence and the abundance of bird species. Unlike humans, these recorders can …

Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

Antipredator defenses and warning signals typically evolve in concert. However, the
extensive variation across taxa in both these components of predator deterrence and the …

The role of colours and colour patterns in behavioural ecology has been extensively studied
in a variety of contexts and taxa, while almost overlooked in many others. For decades …

Papers on sexual selection often highlight the incredible diversity of sexually selected traits
across animals. Yet, few studies have tried to explain why this diversity evolved. Animals use …

The coloration of species can have multiple functions, such as predator avoidance and
sexual signalling, that directly affect fitness. As selection should favour traits that positively …

Support for the role of sexual selection in speciation has grown over the last 30 years. Work
in this area, however, has largely focused on a single dominant question: when and how do …

Despite the predicted purifying role of stabilising selection against variation in warning
signals, many aposematic species exhibit high variation in their colour patterns. The …

Animals settle disputes through contests (Archer, 1988, Hardy and Briffa, 2013, Huntingford
and Turner, 1987). These disputes occur when animals compete to determine priority …

Research on the role of sexual selection in the speciation process largely focuses on the
diversifying role of mate choice. In particular, much attention has been drawn to the fact that …
