We propose a practical concept that distinguishes the particular kind of weaponry that has
evolved to be used in combat between individuals of the same species and sex, which we …

In many species that fight over resources, individuals use specialized structures to gain a
mechanical advantage over their rivals during contests (ie weapons). Although weapons are …

The possibility of using the elemental compositions of species as a tool to identify
species/genotype niche remains to be tested at a global scale. We investigated relationships …

Although rapid adaptive changes in morphology on ecological time scales are now well
documented in natural populations, the effects of such changes on whole-organism …

Summary 1 Relationships between morphology, bite force capacity, prey handling efficiency
and trophic niche were explored in two sympatric species of lacertid lizards, Podarcis …

The masticatory musculature of rodents has evolved to enable both gnawing at the incisors
and chewing at the molars. In particular, the masseter muscle is highly specialised, having …

One of the performance features that is generally considered crucial to increasing the
potential prey spectrum of lizards is bite capacity. In this study we tested whether bite forces …
