Document Summary
He designates loss of biodiversity as most important type of environmental. From late 80s situation has only gotten worse change. Why: it"s irreversible (species extinction is irreversible, a lot of biota is unstudied and unappreciated. Don"t know what these organisms do and might contribute. Number and kinds of living organisms in given area. Species diversity: number of species present in different places across globe. Genetic diversity: studied by evolutionary and population geneticists: interspecific variation, intraspecific variation. Intraspecific genetic diversity has 3 elements: variation within individuals (heterozygosity, variation between individuals in same populations, variation between populations of same species, apply genetic methods to conservation, restoration of endangered species. Focus on all 3 levels of genetic diversity: depending on species might need to focus on different elements of the, different solutions will address loss of genetic diversity at each of the 3 hierarchy of genetic diversity levels. Partitioning genetic diversity (slide 5: variation within individuals - heterozygosity, fast and slow alleles.
