    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
