Module 3 - Conservation
Cards in this deck (22)
- 1conservation science- why do we want to conserve?
- conservation actions
- the future of organisation - 2levels of biodiversity- genetic diversity
- species diversity
- ecosystem diversity - 3genetic diversity- individuals within a species/population have slightly different genes
- important within AND among populations
- provides evolutionary flexibility (more diversity = more likely to adapt)
- capacity of individuals to survive and reproduce helps to drives natural selection
- populations with low genetic diversity can experience interbreeding (i.e. low fertility, high mortality of offspring, deformation) - 4species diversitymorphological/phenotypic species distinguished by visible traits in a species/population
- 5ecosystem diversity- different types of ecosystems within an area (such as Earth)
- 6global biodiversity gradient- biodiversity is not evenly distributed across the planet
- for most taxa, species diversity decreases near the poles and increases towards the tropics
- species diversity reaches a peak in tropical rain forests - 7why is preserving biodiversity important?- ecological and environmental value
- cultural value
- economic value
- intrinsic value - 8ecological and environmental value- if the species is important to other species and so its extinction can have negative cascading effects
- e.g. maybe it is an ecological engineer or maybe it plays an important role in nutrient cycling or seed dispersal - 9cultural value- the worth of a species cannot be financially valued (i.e. religious significance)
- e.g. koala in Australia - 10economic value...
- 11intrinsic value...
- 12how do we benefit from ecosystems?- provisioning services
- regulating services
- cultural services - 13provisioning services...
- 14regulating services...
- 15cultural services...
- 16conservation- upkeep
- preservation
- protection
- management
- safeguarding
- saving - 17foundation of conservation biology...
- 18conservation biology...
- 19central goals of conservation biology...
- 20biological speciespopulations that can potentially breed
- 21ecosystemorganisms (biotic) and their physical environment (abiotic)
- 22ecosystem integrityan ecosystem's ability to support and maintain ecological processes and a diverse community of individuals
