Sexual selection can lead to evolution of both beautiful and bizarre phenotypes, such as peacock trains, deer antlers and the complex displays and bright colours of many lizards. Although we see these tell-tail signs of sexual selection […]
The sex life of Australian water skinks (Eulamprus) has received considerable attention in the past few decades. The Keogh Lab documented alternate reproductive tactics in E. heatwolei and Jess Stapley’s PhD focused in part, on fitness consequences of ARTs. More recently, Dan Noble has been working on ARTs in E. quoyii, and this work will […]
This dispatch comes to you from the Tukai Desert in north-west China, a short drive (about 15 km) from the Kazakhstan border. We are three weeks into a six-week field trip. The lab is currently working on the evolution of complex tail waves and colour signals in Asian toad-headed agamas (Phrynocephalus) in collaboration with Dr. […]

Our study of their visual system reveals remarkably high sensitivity to UV. In fact, they are approximately three times more sensitive to UV than other lizards. You can […]
