Study Notes
Sociobiology
- The systematic study of the biological basis of all social behavior
- Focuses on the ecological and evolutionary aspects of social behavior in animals and humans
Society
- A group of individuals belonging to the same species and organized in a cooperative manner
- Altmann's definition: An aggregation of socially intercommunicating, conspecific individuals bounded by frontiers of less frequent communication
Aggregation
- A group of individuals of the same species, gathered in the same place but not internally organized or engaged in cooperative behavior
- Examples: Winter congregations of rattlesnakes and ladybird beetles
Colony
- A society of organisms highly integrated through physical union of bodies, specialized zooids or castes, or both
- In sociobiology, the word is best restricted to societies of social insects and "colonial" invertebrates like sponges and siphonophores
Individual
- Any physically distinct organism
Group
- A set of organisms belonging to the same species that remain together, interacting with each other more than with other conspecific organisms
- Flexible term used to designate any aggregation or kind of society
Population
- A group of organisms belonging to the same species and occupying a clearly delimited area at the same time
- A geographically delimited set of organisms capable of freely interbreeding under natural conditions
- Deme: The smallest local set of organisms within which interbreeding occurs freely
Species
- A population or set of populations within which individuals are capable of freely interbreeding under natural conditions
- Members of a species do not interbreed with those of other species
- Subspecies: A population that differs significantly from other populations belonging to the same species, separated by distance and geographic barriers
Relationship between Population and Society
- Population is bounded by a zone of sharply reduced gene flow
- Society is bounded by a zone of sharply reduced communication
- The two zones are often the same, as social bonds promote gene flow among members of the society
Communication
- An action by one organism that alters the probability pattern of behavior in another organism in an adaptive fashion
Coordination
- Interaction among units of a group where the overall effort is divided without leadership
- Examples: Fish schools and encirclement of prey by a pride of lions
Hierarchy
- Dominance of one member of a group over another, measured by superiority in aggressive encounters and access to resources
- Examples: Order of access to food, mates, resting sites
Regulation
- The coordination of units to maintain physical or biological variables at a constant level
- Resulting in homeostasis
- Social insects display homeostasis in regulating colony populations, castes, and nest environment
Multiplier Effect
- Small evolutionary changes in individual behavior can be amplified into major social effects
- This can lead to large differences in social organization, even between closely related species
- Example: olive baboons and hamadryas baboons
- Olive baboons have more flexible mating systems, while hamadryas males are possessive of females, which is a key difference in their social organization
Amboseli National Park
- Located in southern Kenya
- Known for its large elephant herds and views of Mount Kilimanjaro
- Home to diverse wildlife including giraffes, zebras, cheetahs, and birds
