  1. 3 levels of biodiversity
    • genetic diversity,
    • species diversity
    • ecosystem diversity

    requires differ tools at differ spatial scales 
  2. mass extinction due to?
    anthropogenic activity 
  3. goals of conservation genetics?
    • understand genetic changes that affect survival of threaed/endangered species 
    • use genetic info to successfully manage threaten/endangered species 
  4. strategies of conservation genetics?
    • preserve genetic diversity (and seek out sustainable environments which foster and maintain biotic diversity)
    • preserve evolutionary processes (hybridization, introgression, and speciation)
  5. anthropogenic factors that risk extinction 
    • land development (habitat fragmentation)
    • overexpoloitation 
    • intro of exotic species 
    • pollution
  6. ecological factors of extinction 
    • environmental fluctuations and catastrophes 
    • metapopulation dynamics - partially isolated population, loss of pathways of immigration, recoloization of sites 
    • small population size (population grown, cooperative interaction, edge effects)
