Sam Jones has started his PhD at RHUL. Sam’s PhD research broadly investigates the physiological and behavioural underpinnings of avian species turnover in tropical mountains. This primarily focuses on the relationship between interspecific aggression and physiology, and its subsequent behavioural consequences. Approaches focus on behavioural and physiological techniques, studying species turnover of Nightingale-Thrushes (Catharus sp.) in Central America that have parapatric distributions and abut at ‘contact zones’ at the edges of their elevational ranges. Sam is a NERC funded student as part of the London Doctoral Training Partnership. Sam is co-supervised by Dr Rob Freeman (ZSL).
