occur roughly between 30° and 40° latitude on the west coasts of continents‚ where offshore there are cold ocean currents. Each region in which the Mediterranean shrublands and woodlands occur is island-like in character and thus there is frequently a high degree of endemism. Comparative studies of the several regional expressions of this biome reveal interesting examples of convergent evolution in plant families and birds (but not among reptiles or small mammals) on the different continents.

Introduction A forest is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest

(Map #1). California itself has five major biomes‚ some of which can be found at RSABG. Four of them are in the California floristic province and the fifth is in both the Great Basin and the Sonoran floristic province. Each of which contains many different types of communities in them. The California floristic province has the coniferous forest biome‚ the oak woodland biome‚ the grassland and marshland biome‚ and the chaparral and coastal sage scrub biome. The Great Basin and Sonoran floristic province

Ecology Essay African lions play a big role in the ecosystem. They are at the top of the food chain and are responsible for 85% of predation in their habitat. They prey on herbivores such as buffalo‚ antelope and zebras. The African lion’s biome is in the tropical grassland and their habitat is the grassy plains of the African savanna. Without the lion‚ the ecosystem would be unbalanced and unstable. The African lion‚ being at the top of the food chain‚ interacts with other organisms in many

BIOMES LAB BIOL 120 `` A biome is a major complex of similar communities. It is the largest ecological unit we recognize. Different books vary in the number of biomes they list. Temperature and precipitation are the two key factors that determine the different type biomes. Some books consider marine ecosystems and freshwater systems as biomes. Others break out wetlands as a biome. We will look at 10 terrestrial biomes: 1. Tundra (Arctic and alpine) 2. Boreal forest or taiga
