Bio 1500 Conservation
1. background extinction: Average rate of extinction occurring over long periods of time between periods
of mass extinction.
2. Mass extinction: in which a large proportion of species became extinct within a few million years.
3. Anthropocene Era: A new geological dominated by the effects of humans.
4. Habitat destruction and alteration: are the most serious threats to biodiversity.
5. Area comparison: this equates to an area nearly as big as Switzerland.
6. Rate of loss: This loss translates to approximately 10 football pitches of forest being destroyed every minute.
7. Drivers of Deforestation: often driven by land being brought under agricultural cultivation, with cattle
ranching being a leading driver in the Amazon.
8. What do invasive species threaten?: Native species.
9. Invasive species: an introduced species that poses a serious threat to native populations.
1/5
, 10. Invasive species direct effects: out competition, predation
11. Invasive species indirect effects: altering the makeup of the native ecosystems (invasive grasses
and butterflies)
12. Plant and wildlife trafficking are what?: are growing dangers to species. (i.e exotic pets, flashy
hunting trophies, bush meat, and traditional medicines drive wildlife traflcking.)
13. Pest and predator control has pushed species to what?: extinction.
14. Endangered Species Act of 1973 (ESA): provides legal protection in the US to both domestic and
foreign endangered species and declares plants and all invertebrate animals eligible for protection.
15. What does ESA require:: Federal agencies to develop programs for the conservation of two categories
of species; endangered and threatened species.
16. endangered species: face the highest danger of extinction
17. threatend species: face a lower danger of extinction.
18. protection of endangered species and their critical habits can often clash
