Social Diversity ( group living) All living is social Howard; songbird territory “A Monogamous Pair” Polygynous territory red wing blackbird marshes [reduce predation] White rhinoceros sets up breeding display [making it with dung and urine] [breeding males cannot walk through it] [territory male don’t like it] [female and children can walk through it] Winer territory mountain lion [wants it own territory to feed on breed] [don’t want other lions to be there to scare deer away] Wolf pack group territory Mawat ● Study wolf pack ● Dumped by plane ● Wait for plane next year [hunt/live together most part of year] [marked his tent with urine; wolf pack walked passed his tent because it was marked] Population consequences 1. Limit breeding individual reproduction max. [prevent over production] 2. Limit population growth “maine gunners” [kill songbirds and will would keep population] [large pool of nonbreeding songbirds that take over nest] Sexual behavior: ecological concentration Lek or Arena Ground nesting birds that are precocial [perform for female] [limits over breeding/ females choice] 10% males → 75% breeding Size and sex Large male few, [deer, fur seals, leks] Large female most common in nature [spiders, fish, insects, birds of prey] Sex and niche Galapagos Marine Iguana [can only go in cold ocean water for only 30 minutes] [maintain body temperature on island] [they cannot move/ don;t have predators]
