Behavioral and physiological adaptations in natural enemies faced with novel hostsNull clines for physiological (solid line) and behavioral (dotted line) adaptation to host defenses as a function of the shape of the cost function. Black points are stable steady states. Arrows represent schematic phase trajectories. k R = 0.1, k B = 0.1, e = 0.1, a = 0.4, f = 20%.Back to article page
