AFRICAN ECOLOGY

Page 2: African ecology

BIOMES• Several types of biomes located on this continent:• Terrestrial• Desert• Grasslands• Savanna• Rainforest• Chapparal

• Aquatic• Rivers• Lakes• Ocean

Biome Types =Precip. and Temperature

Page 4: African ecology

Biome Descriptions• Temperate Grasslands “The Veldt”-South Africa; seasonal variation, moderate rainfall; rich, organic soil; much is used for farming• Savanna (Tropical/Subtropical Grasslands)-distinct seasonal changes, high rainfall (harsh dry season) **alternating wet/dry seasons; rich, organic soil• Desert-very hot and dry; can be cold during the night; little rainfall/plant life• Tropical Rainforest-land areas closest to the equator; most diverse in plant and animal species; abundant rainfall all year• Chapparal-long, hot, dry summers; rainy, mild winters; subject to fires (**helpful to some plant life that needs the fire for their seeds to germinate)

Tropical RainforestFauna• West Africa • mammals (antelopes, bonobo, chimpanzee, gorilla, Mandrill,

scaly-tailed squirrels, otter shrews, duikers, okapi, hippopotamus, Cercopithecus monkeys, bushbabies, pygmy hippo, duiker) • birds (Congo peafowl, African Gray Parrot) and millions of

other animals.

ECOLOGY-FOCUS• Ecology is the study of interactions among organisms and their environments• So….what does this mean for the populations of people in African countries? **People are found in all the biomes discussed**• Ecological Considerations:• Land (Biomes)• Climate• Rainfall• Natural disasters• Food • terrestrial and aquatic availability• Meat sources and Crops grown; Water for drinking

• Healthcare/Pollution/Habitat Stability/Population Growth/Global Warming

• ARE THESE ISOLATED FACTORS OR IS THERE MORE TO CONSIDER?

What are your thoughts???•What connections have you made?•What can you gather from the “small” overview of ecological points given?• Keep in mind: ecology links us all together: men, women, boys, girls, animals, bacteria, fungus, plants, viruses…BUT THIS IS JUST ONE PIECE TO THE PUZZLE.• How does one survive the African experience?
