Biodiversity ofterrestrial ecosystems

1. CONCEPTS IN BIODIVERSITY

1. Concepts

Wilson (1988) Biodiversity (Proceedings)

Biodiversity

Margalef (1996)“...the total specific, taxonomic or genetic richnesscontained in Nature or any local or taxonomic partof it.”

Lovejoy (1980) number of species present

Norse & Mc Manus (1980) genetic d. + ecologic d.

Norse et al. (1986) genes + species + communities

1985 National Forum of Biodiversity, Washington.

Rio Convention

1. Concepts

Wilson (1988)“... a global resource, to be indexed, used andpreserved.”

Biodiversity

UN (1992) The Earth Summit“... the variability among living organisms from allsources including, interalia, terrestrial, marine andother aquatic systems and the ecologicalcomplexes of which they are part; this includesdiversity within species, between species andecosystems.”

Noss (1990)
