Test 3 Biology: Conservation Biology

Front 1

Which factors put species at risk?

Back 1

habitat reduction
habitat fragmentation
small population size
genetic erosion in a population
the commercial value of a species

Front 2

What are the consequences of habitat fragmentation?

Back 2

Habitat fragmentation can prevent inter-breeding between the isolated sub-populations of species.

This results in inbreeding, genetic erosion, and reduced overall health.

Front 3

What are wildlife corridors?

Back 3

Wildlife corridors connect habitat fragments. They allow interbreeding between isolated sub-population.

Front 4

What is a major benefit of a corridor that connects reserves in biodiversity hotspots?

Back 4

Corridors that connect reserves in biodiversity hotspots can have a magnifying effect that increases species number.

Front 5

What is population augmentation?

Back 5

Population augmentation is the introduction of genetically-distinct individuals into a genetically-eroded sub-population to create genetic variation.

Front 6

What are major risk factors for marine ecosystems?

Back 6

The loss of key biodiversity centers is a major risk for marine ecosystems.

fishing

Front 7

What are the causes of coral reef ecosystem decline?

Back 7

disease, changes in temperature, and changes in pH

Front 8

What is the use of plants in bioremediation called?

Back 8

phytoremediation

Front 9

What is bioremediation?

Back 9

Bioremediation is the use of select species to reduce toxin levels in contaminated water and soils.

Front 10

What is restoration ecology?

Back 10

Resoration ecology seeks to initiate or accelerate the recovery of degraded ecosystems.
