Savanna Biome It occurs in regions that has a distinct wet/dry climate category. Dry season in the winter and wet season in the summer. Subtropical region. During dry season most plants die and most animals migrate to find food. Temp. ranges from 68-86 degrees F Mainly in low latitudes (between 30°S-30°N)
Savanna Biome Precipitation is 15- 30 inches a year
Human Impact Human impact: humans create savannas by burning the grasslands and cutting down trees in order to plant crops. Big game hunting Poaching animals
Animals Animal adaptations: animals have adapted to great variability in the food supply. Africa - aardvark, African elephant, African wild cat, antelopes, buffalo, Cape hunting dog, caracal, cheetah, eland, gerenuk, giraffe, gnu, Grant's gazelle, hippopotamus, hyena, impala, jackal, kudu, leopard, lion, Australia - kangaroo, wallaby, pigeon, dove, parrot, finch, wombat South America - rodents (like the capybara), rhea, and deer. India - Asiatic water buffalo, Asian elephant, Indian rhinoceros, Indian wolf, tiger, savanna nightjar Myanmar-Thailand - Asian elephant, Asiatic Water buffalo, pygmy hog, tiger
Plants Plant adaptations: many plants have developed adaptations that allow them to grow quickly when there is water. When the water is scares they turn brown to limit water loss Type of plants: Baobab tree, sausage tree, Strangle fig, Wild date palm, Tooth brush tree, Umbrella tree, Elephant grass, and Bermuda grass.
Woodland: trees are spaced rather broadly apart because of soil moisture during the dry season is not sufficient to support a full tree cover. Thorn-tree-tall-grass: trees are more widely scattered, and open grassland is more extensive than in the savanna woodlands Savanna Biomes
Tundra Biome This tundra is the coldest of all biomes Tree-less plane Little precipitation (less than 10 in.), poor nutrients, and poor growing seasons Gets energy and nutrients from dead or organic material Temps cold most of year, maybe short periods warmer than 0°C (32°F) Mainly in high latitudes (60° - 80°N) and high elevations
Human Impact Increase in Earth temp melts polar ice caps. Pollution for mining and drilling of oil has polluted the natural resources. Nickel minds in Russia are so polluted plants around mine have died off. Big game hunting
Plants and Animals Plants: Arctic: low shrubs, sedges, reindeer mosses, liverworts, and grasses,400 varieties of flowers, and crustose and foliose lichen Alpine: tussock grasses, dwarf trees, small-leafed shrubs, and heaths Animals Arctic: Herbivorous mammals: lemmings, voles, caribou, arctic hares and squirrels, Carnivorous mammals: arctic foxes, wolves, and polar bears Migratory birds: ravens, snow buntings, falcons, loons, ravens, sandpipers, terns, snow birds, and various species of gulls, Fish: cod, flatfish, salmon, and trout Alpine: Mammals: pikas, marmots, mountain goats, sheep, elk, Birds: grouselike birds, Insects: springtails, beetles, grasshoppers, butterflies
Tundra Biomes Arctic: It is located in the areas around the poles, the growing range is 50-60 days, the precipitation is 6-10 in., and where there is permafrost. Alpine: It is located in the mountains at high latitudes where trees cannot grow. The growing season is 180 days in the summer.
