GGR100H1 Chapter Notes - Chapter 20: Arctic Air, Temperate Broadleaf And Mixed Forest, Terrestrial Ecosystem
Document Summary
Invasive species: alien species that arrive in a new ecosystem, being disruptive, possibly altering community dynamics leading to a decline in native species populations. Tropical rainforest: earth is girdled with this lush biome (correlates with itcz, consistent year-round day length, high insolation, avg. annual temperatures around 25 degrees celsius, plentiful moisture, amazon region, equatorial regions of africa, indonesia, madagascar, southeast asia, Large expanses of grasslands interrupted by trees and shrubs: transitional biome between tropical forests and semi-arid steppes and deserts. Less than 6 months of precipitation when influenced by itcz, rest of the year is dry: xerophytic, drought resistant. Largely found in africa, tanzania, kenya, sahel, sections of australia, india, south. Large land mammals, zebra, giraffe, buffalo, gazelle, wildebeest, antelope, rhino, elephant, grazers: birds, ostrich, eagle, snakes, crocodile. Midlatitude broadleaf/ mixed forests: moist continental climates support mixed forest, warm to hot summer, cool to cold winters. Midlatitude grasslands: most modified biome by human activity.
