Habitat Fragmentation Quiz

What is the main concern of the study on global habitat fragmentation?

• The loss of plants and animals (species diversity)

• The negative effects on ecosystems

• The reduction of forest lands (habitat diversity)

• The encroachment of urban development

What percentage of existing forest lands are within a half-mile of the forest edge?

• 60%

• 40%

• 70%

• 20%

How much does habitat fragmentation reduce the diversity of plants and animals?

• 13 to 75%

• 26 to 50%

• 13 to 25%

• 76 to 100%

How might birds migrating to boreal forests to breed be affected by habitat fragmentation due to human development?

• Increased habitat diversity

• Increased competition between species for resources

• Decrease habitat diversity

• Increased edge effect

What is one possible way to mitigate the negative effects of habitat fragmentation?

• Increasing agricultural efficiency

• Decreasing landscape connectivity

• Expanding urban development

• Reducing forest conservation

Which habitats are experiencing the largest negative effects of habitat fragmentation?

• Smaller, most isolated habitats

• Largest, most isolated habitats

• Smallest habitat located next to a large national park

• Largest habitat located next to a large national park

What do the results of the study show about the negative effects of habitat fragmentation over time?

• 50% or higher decline in species diversity

• Result in disruptions to the natural cycling of nutrients

• They decrease

• Result in changes to how the ecosystem functions as a whole

Which is an effective method mentioned for improving landscape connectivity?

• Conserving and maintaining larger areas of habitat

• Increasing agricultural efficiency

• Focusing on urban design efficiencies

• Utilizing landscape corridors

How would you describe the edge effect?

• Increased risk of predation/other risk factors due to proximity to areas outside of normal habitat

• Decreased risk of predation/other risk factors due to proximity to areas outside of normal habitat

• Increased habitat range leading to an increased edge

What is the main message of the study on habitat fragmentation?

• Habitat fragmentation affects ecosystem services that humans benefit from.

• Habitat fragmentation is beneficial

• Habitat fragmentation is a natural process

• Habitat fragmentation has harmful effects on biodiversity
