REGNRSG 105 Lecture Notes - Ecosystem Services, Species Richness, Phylotype
Document Summary
The term was invented in 1985 to catch the attention of policy makers & general public to raise awareness and commitment to the problems of nature. By 1992 there already was a un convention & supported by world: except for u. s. It was a successful idea that nature was decreasing political concept. For biologists: taxonomic diversity, genetic diversity, ecological diversity. The variability among living organisms from all sources, including diversity within species, between species, and of ecosystems this includes gmos organized species are the lowest level however, you can still go down. Taxonomic diversity: tries to capture the tree of life, which is hierarchically. Taxonomic level of domain & kingdom = bacteria are main to levels of populations and individuals. Higher taxonomic units are not well defined. Amount of species: earth = 8 million, netherlands = 45,000 that go extinct = speciation > extinction in, both species adapt to eating/specializing in one food type (nuts example)
