About
Jeffrey A. Walker is an evolutionary biologist whose research centers on the intersection of animal behavior, sensory ecology, and evolutionary dynamics. His most-cited work, "A Matador-like Predator Diversion Strategy Driven by Conspicuous Coloration in Guppies" (2020, 18 citations), reveals a striking anti-predator mechanism: male guppies use bright coloration not merely to attract mates, but to actively lure predators away from their own trajectory—a "matador" maneuver that diverts attacks. This finding challenges conventional views on conspicuous coloration, demonstrating its dual role in both sexual selection and predator evasion. Walker’s broader contributions include experimental and theoretical frameworks for understanding how visual signals evolve under conflicting pressures, with implications for behavioral ecology and conservation. His work has been cited over 500 times, reflecting its influence on studies of predator-prey interactions and signal evolution. A professor at the University of Southern Maine, Walker is also known for his accessible teaching and open-science advocacy, making him a key figure in bridging rigorous evolutionary theory with real-world biological complexity.
