Sex and refuge distance influence escape decision in a Liolaemus lizard when it is approached by a terrestrial predator

The decision of when and how to escape result crucial for animals because it can result in an interruption to contribute to their fitness. In the present study, we analysed whether speed attack, sex and type of refuge influenced the flight initiation distance (FID) and the closest refuge distance (C...
