Primate Biomes Flashcards
Biome
a major community, classified by the predominant vegetation, such as grassland or rainforest and characterized by adaptations of life to that particular environment
Biome Implications
Because not all biomes will be able to support the same number and types of animals, animals (primates) living in different biomes have developed different strategies for survival
Major Primate Biomes
Major primate biomes of the Earth are Tropical, but habitats can be quite different; Temperature and Precipitation determine major terrestrial Biomes; Depends on location- close to the equator or further away affects day length, climate, etc
Tropical
Located between the Tropic of Capricorn and Tropic of Cancer; Average Temperature (C)20-30, Annual Precipitation (cm) ~50-500; Three types:
- Tropical Rainforest
- Tropical Deciduous Forest
- Tropical Grasslands
Tropical Rainforest
-High rainfall - High temps
-100in (8+ ft) of rainfall/yr - constant amount/month
Temps consistent high
-Most plant species are evergreen (dont have seasonal changes)
-Layers: Emergent: full sun all day
-Canopy: arboreal highway 3/4 sun, trees don’t overlap
-Understory: 1/2 sun
-Shrub/Forest floor: 1/4 sun- very little sun - dark
Tropical Dry Forest
- less canopy
- seasonal trees
- less trophic levels
- Fewer forest layers; trees further apart w/few continuous canopy
- More seasonal rainfall and thus food availability is more seasonal
Challenges of Tropical Dry Forest
- Locomotor challenges: stratification reduced and trees further apart w/few continuous canopies
- Dietary challenges: more seasonal foods
- Predators and other dangers (raptors, carnivores, snakes)
Tropical Grassland (savanna)
- Lots of biomass- big animals big herds not a lot of biodiversity
- Rainfall here is reduced (10-30in/yr) and very seasonal -Temps are stable
- Fewer niches=less species biodiversity (# of species) than in the tropical rainforest
- But density (# of animals of any species) is much greater
- Trees are present but tend to be sparsely distant w/grasses the most conspicuous plant
Challenges for Tropical Grasslands
- Sleeping sites (rocky outcrops)
- Seasonal food (spikey foods, galls w/ants)
- Predators (leopards, lions, hyenas, raptors)
Temperate Forests
- Of the 200 species of primates, only a few are able to live in this habitat
- There are 4 definite seasons
- Most of the trees lose their leaves in the winter
- Rainfall varies considerably
Challenges for Temperate Forests
- leafless trees create food challenges
- Thermal challenges and cold temps
- Limiting factors include predators, drastic seasonal foods and the climate itself
Challenges for Tropical Rainforest
-Dietary challenges:
Secondary compounds - poisons in leafs
Mechanical Properties of foods - like nuts
-Predators: Harpy eagle, tigers, poisonous snakes
