For almost 40 years, studies of whole-organism performance have formed a cornerstone of
evolutionary physiology. Although its utility as a heuristic guide is beyond question, and we …

Through dishonest signals or actions, individuals often misinform others to their own benefit.
We review recent literature to explore the evolutionary and ecological conditions for …

Highlights•Crustaceans produce large but weak claws as dishonest signals of their
strength.•Crayfish did not use large, weak claws as signals during territorial …

Crustaceans are known for their ability to autotomize and regenerate their appendages. The
appendages that are most often autotomized are their chela, often specialized as claws …

Understanding the processes that promote signal reliability may provide important insights
into the evolution of diverse signalling strategies among species. The signals that animals …

Much research on animal communication has addressed how costs such as social costs or
physiological costs favor the accuracy of signals. Previous work has largely considered …

In many species, individuals contest resources using specialized morphologies to
overpower rivals, hereafter referred to as weapons. Despite their importance in fights, little is …

Signals of dominance and fighting ability (ie status signals) are found in a wide range of taxa
and are used to settle disputes between competitive rivals. Most previous research has …

It is essential to incorporate mechanisms of biotic resistance into predictions of ecological
impact conferred by invasive species. Trophically and functionally analogous native species …

A major challenge in the study of animal communication is distinguishing whether signals
convey honest or dishonest information. Biologists infer the honesty of a signal from its …
