BIOLOGY 171 Lecture Notes - Lecture 24: Invasive Species, Florida Panther, Ecological Footprint
Document Summary
The modern era, so named to reflect the dominant impact of humans on earth. Normal extinction of various species as a result of changes in local environmental conditions. The aggregate number of species, or, more broadly, also the diversity of genetic sequences, cell types, metabolism, life history, phylogenetic groups, communities, and ecosystems. The management of nature and of earth"s biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. The quantification of individual human claims on global resource by adding up all the energy, food, materials, and services used and estimating how much land is required to provide those resources. Species dies off and no longer exists. Improve environment for the species that used to live there. Changes are measured against previous baselines, which likely represent significant changes from the original state. 80% of world"s described species are invertebrates.
