Animals often find themselves in direct competition with other individuals for resources and mates. Because fighting is costly, many species honestly signal their fighting ability to avoid injury (non-escalated fights). For example, in flat lizards (Platysaurus broadleyi), males can resolve dominance status by displaying their UV-reflective throats to their opponent. . . . → Read More: Why do winners keep winning?
Marco Barquero’s hard work has paid off! For his PhD, Marco travelled far and wide in his quest to study signalling in Jacky Dragons. Chapter 1 has just been published in Behavioral Ecology and Sociobiology. Marco studied three populations for which we had genetic data (thanks to Mitzy Pepper and Scott Keogh at . . . → Read More: Jacky Dragons have labile displays and don’t discriminate among populations
Interested in colour signals and wondering about the best approaches to researching colour and what you should be reporting? Two recent papers from members of the lab and fellow researchers at Macquarie and elsewhere should help! In the first paper, Kemp et al. provide a framework for studying animal colour. This is not a . . . → Read More: Do you study colour? Hot (and warm) off the press!
Take a look at photos from our field work in northern China, where we were studying complex communication in toad-headed agamas (Phrynocephalus).

Recently, the Pryke Lab published its first paper on a reptile—the iconic Frillneck Lizard (Chlamydosaurus kingii). Both males and females have frills and until now, the consensus has always been that frills play a role in anti-predator behaviour. Not only does the frill startle a would-be predator, . . . → Read More: Better red than dead? Fiery frills win more contests in the Australian Frillneck Lizard
