  • Conservation of Biodiversity
    • 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
      • biotic index - compares the relative frequency of indicator species
    • 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
    • richness and evenness are components of biodiversity
      • richness - number of different species present
      • evenness - how close in numbers each species is
    • biogeographic factors affect species diversity
      • large nature reserves vs smaller ones
      • connected nature reserves vs isolated ones
