Environment: The World's Biomes (Museum of Paleontology, UC Berkeley)

"Explore our planet's biomes - environmental divisions defined by the community of organisms adapted to live within them. This includes forest, desert, tundra and more....Biomes are defined as 'the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment' (Campbell 1996)....Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all." -- from the website. <http://www.ucmp.berkeley.edu/>
