the number and relative abundance of species in a biological community
The variability in the genetic make up among individuals within a single species. In more technical terms, it is the genetic differences among populations of a single species and those among individuals within a population.
**Different individuals having different versions of genes
The variety of ecosystem types (for example, forests, deserts, grasslands, streams, lakes, wetlands and oceans) and their biological communities that interact with one another and their non-living environments.
a species that could become endangered in the near future
a species whose numbers are so small that the species is at risk of extinction
species that are native to and found only within a limited area
A biodiversity hotspot is a biogeographic region with a significant reservoir of biodiversity that is under threat from humans.
forgiveness of (some) international debt in exchange for nature protection in developing countries.
financial transactions in which a portion of a developing nation's foreign debt is forgiven in exchange for local investments in conservation measures.
U.S. Endangered Species Act
a Federal legislation that aims to conserve the ecosystems upon which endangered and threatened species depend.
to provide protection for species that are in danger of extinction and to conserve the habitats on which those species depend.
Evolution seeks to explain creation of life.
*it's actually more interested in the modification of a species after it came into being
Evolution is goal oriented
*one cannot know genetic variants and which will be available to natural selection and can't predict environmental conditions
Evolution produces perfect adaptations
-adaptations are compromises between differing needs
