Document Summary
In adults, strong competition between males for females. Bold fish learn more quickly than inhibited fish but only in experiment 1. Know the case study of predator inspection and boldness in guppies. Guppies differ in their tendency to inspect predators: inspectors and non-inspectors behave consistently around predators. Color change in atlantic salmon: aggression involved in defending territory, dominant males develop dark vertical eye bands. What was the experimental setup of stickleback fish. Game theory models often based on contrasting behavioral strategies: if strategies persist over time, they become like personality traits. *novelty trumps shininess", palatability: may be linked to scavenging nature. Ess (evolutionarily stable strategy) a balance between 2 personality types. And what are the 2 types of coping styles observed in rodents: proactive = territorial control, aggression, more likely to remove negative stimuli, reactive = immobility, low aggression, more likely to hide from negative stimuli. Predicts that more evenly matched opponents will engage in more dangerous behaviors.
