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

2 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

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

4 Mating Behavior

5 Disadvantages of Group Life Competition for resources Diseases Parasites

6 Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy

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