Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions

Group Living Animal society – stable group of individuals of the same species that have cooperative relationships outside of mating and raising young. Invertebrates and vertebrates

Advantages to Group Life Protection from predators Increase feeding efficiency Protection from elements Easy access to potential mates

Mating Behavior

Disadvantages of Group Life Competition for resources Diseases Parasites

Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy

Altruism Individual sacrifices reproductive potential for the benefit of others in the group – Honeybees – Turkeys – Naked mole rats Kin selection
