Animal colour patterns remain a lively focus of evolutionary and behavioural ecology,
despite the considerable conceptual and technical developments over the last four decades …

The largest family of spiders, jumping spiders (Salticidae), is known for performing complex
visually mediated predatory and courtship behavior. As cursorial predators, they rely on their …

The origins of preferences that drive the evolution of arbitrary sexual signals have been hotly
debated for more than 150 years. An emerging but little-tested theory, efficient coding theory …

Examining the role of color in mate choice without testing what colors the study animal is
capable of seeing can lead to ill-posed hypotheses and erroneous conclusions. Here, we …

How animals assess information encoded in individual color patches have been extensively
studied, yet the role of both individual color patches and gross color pattern (ie, the …

We examine the distributed visual system of spiders, an ancient and diverse lineage of
predators. Across families, prey-capture strategies include active pursuit, sit-and-wait …

Communication in cuttlefish includes rapid changes in skin coloration and texture, body
posture and movements, and potentially polarized signals. The dynamic displays are …

Background Skinner-box systems are fundamental in behavioural research. They are
objective, reliable and can be used to carry out procedures otherwise impossible with …

Understanding diversity has been a pursuit in evolutionary biology since its inception. A
challenge arises when sexual selection has played a role in diversification. Questions of …
