Book Description
Male side-blotched lizards use differential reproductive tactics. Some individuals are territorial and defend a territory, while others are non-territorial and do not defend any territory. The defense of the territories most likely involves spatial cognition and covaries with brain attributes. Along with the variation in territoriality and the area of the territory defended by an individual, the levels of testosterone also covary. Testosterone has been seen to affect the brain outside of territorial defense. It is likely that the increased demands of spatial cognition and higher levels of testosterone are related to an underlying mechanism. We predicted that increased testosterone levels in an individual will lead to an increase in neuron soma size. We examined territorial and non-territorial males who were castrated or castrated plus testosterone supplemented to ascertain the effects of territorial status and testosterone on medial cortex neuron soma size. We predicted that territorial status and testosterone levels would interact to produce differences in soma size. However, we did not find a significant difference in neuron soma size across the treatment groups.

Book Description
When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions – these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
