ANP lecture 15 & 16 Flashcards
Study of interrelationships of animals, plants and their physical environment
Ecology
Study of relationships between primates and their environment
Primate Ecology
filter between an organism and its genetic makeup
environment
leaf-eaters
folivores
fruit-eaters
Frugivores
Primates that forage at dawn and dusk
crepuscular
Primates that have irregular active periods during both the day and night (owl monkeys)
cathemeral
Brachiate in asian forests, eat fruits as their dietary staple
Gibbons
walk a few hundred yards in a day, their high-mountain habitat contain no fruit trees so their diet is manly wild celery and other highly fibrous plants
Mountain Gorilla
Live in tropical forests and eat fruits/leaves. Travel 2 miles per day to find fruit trees
lowland gorilla
competition between members of a group (within a group)
intragroup feeding competition
competition between two groups
intergroup feeding competition
direct squabbling over food, very common among frugivorus group-living primates
contest feeding completion
when feeding competition occurs but enough food exists so that every animal gets some food
scramble feeding competition
poor health, lower dominance rank and lowered fertility
effects of feeding competitions
All mammals including nonhuman primates live in defined places
home range
part of the home range that is used most intensively is
core area
In some species the home range is defended against other members of the same species
territory
During lean session _______ falls back on fibrous plants
gorillas
During lean seasons ______ continue to forage widely for fruit
Chimpanzees
Some primates from two, three or more more species that travel and feed together for part or all of each day
polyspecific group/associations
