How does habitat fragmentation reduce genetic diversity in species?

• Habitat fragmentation makes nonnative species introduction possible.

• Habitat fragmentation opens migration routes.

• Habitat fragmentation isolates a large population into smaller groups.

• Habitat fragementation encourages open gene flow.

The illegal hunting, fishing, harvesting, and trade of wildlife

• pollution

• poaching

• ingathering

• black market deals
