Study Notes
Social Behavior
- A key factor influencing social behavior among different species is the evolution of diverse social groups.
- Cooperative care of juveniles and reproductive division of labor are characteristics of a specific type of social group structure.
Social Group Structures
- Eusocial colonies have a reproductive queen or dominant individuals, and exhibit a division of labor within their colonies.
- Permanent groups with dominant pair structures or matrilineal societies are another type of social group structure.
- Matrilineal societies are distinct from matriarchal societies, where the dominant individual is not necessarily the female.
Territorial Behavior
- Defending a physical space containing essential resources for survival and reproduction is a characteristic of territorial behavior.
- Territorial behavior is typical of social animals, where individuals position themselves at the center of a large group to reduce predation risk.
Evolution of Social Groups
- The evolution of diverse social groups in animals is influenced by factors such as competition for resources, predation pressure, and mating systems.
Mating Systems
- Different mating systems influence social organization, with lek mating systems being a type of polygynous mating system.
- The evolutionary puzzle surrounding the maintenance of genetic variation in traits associated with mate choice within lek mating systems is known as the "lek paradox".
- The "good genes" hypothesis attempts to explain the maintenance of genetic variation in traits associated with mate choice within lek mating systems.
Benefits and Drawbacks of Group Living
- A key benefit of understanding social structure and membership in group living is the ability to predict and explain animal behavior.
- Territorial behavior provides a common benefit of reduced predation risk.
- Group living enhances feeding efficiency, but also increases the risk of disease spread and attracts predators.
- One advantage of group living is that it makes it less likely for any given individual to be preyed upon.
Primate Societies
- In primate societies, mating systems and social organization are driven by factors such as competition for resources and mate choice.
- One implication of mate choice and social organization in mating systems is that it leads to diverse mating strategies and social structures in primate societies.
- Behavior often involved in mate choices includes elaborate courtship displays to attract mates, known as leks.
