ANT333Y1 Lecture Notes - Lecture 15: Common Brown Lemur, Weaning, Parallel Evolution
Document Summary
Ant333 lecture #15 primate socioecology & behavioural ecology. A dynamic system expressing the interactions of a number of factors within both the ecological and social milieux that influence the spatial dispersion and grouping tendencies of populations (crook, 1970:198). Socioecology seeks to explain the evolution and maintenance of social groups and mating systems. Focused on correlation between diet categories & group size. Proposed variety of possible phylogenetic pathways to explain evolution of different social structures. For example, cohesive multi-male groups could have evolved originally from solitary individuals and gone through phases as pair-bonded groups and uni-male groups with extensive contact with females. Compared ecological and behavioral factors (diet, home range, body size, activity cycle, and social structure) in 100 primate species. Congeneric species in different ecological categories showed different social structure. Frugivores of related species live in larger groups than folivores (e. g. , lemur catta and lemur fulvus rufus). Other correlations demonstrated between morphology and habitat type.
