Scientists collaborate with other agencies—the preservation of species involves international cooperation through intergovernmental and non-governmental organizations. (4.3)
Understandings:
An indicator species is an organism used to assess a specific environmental condition
Relative numbers of indicator species can be used to calculate the value of a biotic index
In situ conservation may require active management of nature reserves or national parks
Ex situ conservation is the preservation of species outside their natural habitats
Biogeographic factors affect species diversity
Richness and evenness are components of biodiversity
Applications:
Case study of the captive breeding and reintroduction of an endangered animal species
Analysis of the impact of biogeographic factors on diversity limited to island size and edge effects
Skills:
Analysis of the biodiversity of two local communities using Simpson’s reciprocal index of diversity
