| Question | Answer |
|---|---|
| range within upper and lower limits, of a limiting factor that allows a species to survives and reproduce | range of tolerance |
| pattern where species richness increases as one approaches the equator | latitude gradient in species richness |
| searching for organisms that might provide new foods, medicine, or products; includes endagered animals and those who may go extinct before discovering subtances | bioprospecting |
| index expressing how large the average population size of a species is. now compared to a baseline year of 1970 | living planet index |
| occurs when the last member of a species dies and the entire species ease to exist | extinction |
| loss of a species from one area but not the entire world | extirpation |
| pace which organisms independently go extinct | background extinction rate |
| events that eliminated atleast half of the species on earth | mass extinction event |
| list of all species facing high ricks of extinction; releasd by International Union for Conservation of Nature | red list |
| urban sprawls, farming, grazing, clearing forests, etc are examples of _____ | methods of habitat loss |
| habitat loss mostly occuring through gradual piecemeal degredation; smaller habitats and preventing movement betwen organisms habitats | habitat fragmation |
| pollution type that degredrades forests affecting atmosphere and climate | air pollution |
| pollution type that affects behavior and habitat use of animals | noise pollution |
| pollution type that directly harms fish and amphibians, farm runoff, heavy metals and plastics | water pollution |
| removing species at faster rates than they can reproduce, ex: valuable trees, exotic meat hunting, overfishing | overharvesting |
| illegeally killing of wildlife for meat or bodyparts; likely sen in k-selected species; ex; African Elephants | poaching |
| non-native species introduces to new environments, and proliferae and displace native species; species that native to islands are partiticaly vulnerable to invasive species | invasive species |
| causes animals to shift their range to be closer to the poles or higher in altitude | climate change |
| study that seeks to understand the loss, protection, and restoration of biological diversity | conservation biology |
| act that offers protection to species that are considered threatened or endagered | Endagered Species act of 1973 (ESA) |
| category of species that are likely to become endagered soon | threatened |
| category of species in danger of becoming extinct soon | endagered |
| convention that regulated trade of endagered species and their body parts prohibits most thretned species | 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flor |
| convention that started providing funding and incntives for conservation in devloping countries | 1992 Convention on Biological Diversity |
| endagered individuals are bred and raised with the intention of reintroducing their progeny into the world | Captive breeding |
| consists of taking DNA from an endagered species inserting it into an egg from a related species and implementing it into a female | cloning |
| analysis of evidence to make an identificaltion or answer relating to a crime; can be used conservation biology | forensic science |
| species that are large and roam great distances, acts as a kind of umbrella to protect many other species | umbrella species |
| used by environemntal speicies to promote convervation; usually iconic charismatic vertebrates (the giant panda) | flagship species |
| regions that support a great number of species that are found nowhere else; harboring at least 1,500 endemic species and already lost 70% of its habitat area | biodiversity hot spots |
| areas that are seeking to maintain habitats and ecological services; may still be affected by illegal actitivy | protected areas |
| human-assisted movement of individuals beyond their species current range or within their range, relocating them from rapidly changing areas to more sustainable areas | assisted migration |
