Document Summary
The ecological niche : where you live, what you eat, when you are active (diurnal, nocturnal, etc. , how you move (terrestrial, arboreal, etc. ) Calories: provide specific nutrients, minimize exposure to toxic chemicals. Some have adaptations to digest toxic chemicals. Influenced by body size and basal metabolic rate (bmr) - ex: gorilla has low bmr, can eat more low quality food. Food distribution : leaves: abundant and available year round, fruits and seeds: seasonal and patchy. Insects: year round, but low densities and mobile: higher density and availability = can live in big groups because less competition exists. Most are terrestrial and live in savannahs. One male, several females, and their young. Females are usually all related and share a close bond. One breeding females, several males, and their young. Group of many males and females that break into smaller groups when less food is available.
