Limiting factors of temperate grasslands
Nettet7. jan. 2024 · Plants – Grasslands make up one of Earth’s major terrestrial biomes. Dominated by grasses and shaped by other biotic factors, different types of grasslands exist in tropical and temperate climates. Tropical grasslands cover much of Africa, Australia, South America and India, including the African savanna. NettetThe temperate grasslands, or prairies, form a belt between forest and desert, mainly on the Great Plains but also on the mid-slopes of the intermontane basins, above the salty desert flats. At the “break of the plains” on the eastern subhumid margin, invaded by rain-bearing tropical gulf air in spring and early summer, the grasslands consist of a dense …
