Chap. 56 Conservatio

Campbell Biology Chapter 56: Conservation Biology and Global Change

QuestionAnswer
Restoration ecology Applies ecological principles in an effort to return degraded ecosystems to their natural, predegraded state.
Conservation biology Integrates ecology, physiology, molecular biology, genetics and evolutionary biology to conserve biological diversity at all levels.
Components of biodiversity 1. Genetic diversity 2. Species diversity 3. Ecosystem diversity
Introduced species Can quickly disrupt an ecosystem because its normal competitors and predators are not in its new environment to control its population.
Endangered species One that is in danger of extinction throughout all or a significant portion of its range.
Endemic species Species that are found no where else in the world; their habitat is restricted to one space or area on the globe.
Threatened species Are considered likely to become endangered in the near future.
Threats to biodiversity 1. Habitat loss 2. Introduced species 3. Overharvesting 4. Global change
Overexploitation Overharvesting; refers generally to the human harvesting of wild organisms at rates exceeding the ability of populations of those species to rebound.
Fragmentation Breaking up a large habitat area into many smaller areas. These smaller areas may not be large enough to support the original community of species.
Movement corridor Allows for exchange or mobility of animals between small areas of habitat.
Minimum viable population Smallest population at which a species is able to sustain its numbers and survive.
Biodiversity hotspot A relatively small area with an exceptional concentration of endemic species and a large number of endangered or threatened species.
Bioremediation The use of living organisms, usually prokaryotes, fungi, or plants, to detoxify polluted ecosystems.
Biological augmentation Uses organisms to add essential materials to degraded ecosystems.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
