option C.4: (Core) Conservation of biodiversity
Essential idea:
- Entire communities need to be conserved in order to preserve biodiversity
Nature of science:
- Scientists collaborate with other agencies—the preservation of species involves international cooperation through intergovernmental and non-governmental organizations. (4.3)
Understandings
C 4.1 U An indicator species is an organism used to assess a specific environmental condition.
C 4.2 U Relative numbers of indicator species can be used to calculate the value of a biotic index.
C 4.3 U In situ conservation may require active management of nature reserves or national parks..
C 3.4 U Ex situ conservation is the preservation of species outside their natural habitats.
C 4.4 U Biogeographic factors affect species diversity
C 4.6 U Richness and evenness are components of biodiversity
