The main terrestrial ecosystems Modified from C.Hill 10/26/2009
3
Tundra Permafrost, continuously frozen ground Large mammals with good insulation that include: musk oxen and caribou Smaller animals include: lemmings, arctic fox, and snowy owl.
4
Tundra Northernmost limits of plant growth High altitudes Little precipitation Extremely cold winter air temperature Alaska, Canada, Scandinavia, and Russia
5
Taiga: Coniferous Forests Cone-bearers Spruce, Pine, Fir, and Hemlock Harsh winters, short summers Thin, acidic soil
6
Taiga: Coniferous Forests Taiga, the most extensive, stretchs across North America and Eurasia reaching the southern border of the artic tundra.
7
Deciduous Forests Sufficient moisture Large trees Oak, Hickory, Beech, and Maple Experience each season
8
Deciduous Forests Dominates most of the eastern United States Soil rich in inorganic and organic nutrients Support speices such as: arthropods, birds, small mammals, bobcats, foxes, black bears, and mountain lions
9
Mediterranean forest Dense, spiny shrubs Tough evergreen leaves Mild, rainy winters Long, hot, dry summers
10
Mediterranean forest Require occasional fires for long-term maintenance Plants regenerate quickly Animal browsers such as: deer, fruit- eating birds, seed-eating rodents, lizards, and snakes
11
Deserts Sparse rainfall Rapid evaporation No perennial vegetation Scattered shrubs and cacti
12
Deserts Desert plants and animals adapt to drought and extreme temperatures Only active during cooler nights Conserve water and seed-eaters such as: ants, birds, rodents, lizards, snakes and hawks
13
Savanna Dominated by grasses and scattered trees Frequent fires Rapid growing grass, good food source
14
Savanna tropics in central South America central and South Africa; home to giraffes, zebras, antelopes, baboons, lions, and cheetahs.
15
Tropical Rain Forest Rain is abundant Poor soil Large trees Closed canopy
16
Tropical Rain Forest Found in very humid equatorial areas such as: o Indonesia o Amazon River basin
