About

John A. Endler is a pioneering evolutionary biologist and ethologist whose research has fundamentally reshaped our understanding of animal colouration, sensory ecology, and natural selection. His work bridges the gap between visual perception and evolutionary pressures, demonstrating how animals perceive and use colour in complex environments. Endler’s landmark studies on guppies revealed how predation risk and mate choice drive the evolution of vivid colour patterns, providing a classic example of sexual selection in action. His influential 1998 paper, "Colour perception and the use of video playback experiments in animal behaviour" (104 citations), established rigorous methodologies for studying animal vision, ensuring that experimental stimuli accurately reflect how subjects perceive the world. This work has been cited over 3,000 times across his career, underscoring its impact on behavioural ecology and sensory biology. Endler also made seminal contributions to the theory of camouflage, aposematism, and the role of light environments in colour signal evolution. A Fellow of the Royal Society, his interdisciplinary approach—integrating physics, neurobiology, and field studies—continues to inspire new generations of researchers exploring the dynamic interplay between organisms and their sensory worlds.
