Ants To Grizzlies (Theory of Island Biogeography)

What is a significant consequence of human population expansion on natural habitats?

• Increased biodiversity in urban areas.

• Expansion of wilderness areas.

• Shrinking and fragmentation of habitats.

• Improved animal migration routes.

What event in E.O. Wilson's childhood led him to focus on studying small organisms like insects?

• A fishing accident that damaged his eyesight.

• A school project on local wildlife.

• His family's move to a new city.

• A gift of a microscope from his parents.

What natural event allowed E.O. Wilson to test his "rule of thumb" regarding species repopulation on islands?

• A major earthquake in the Pacific.

• The volcanic eruption of Krakatoa.

• A severe hurricane that hit multiple islands.

• A prolonged drought in the South Pacific.

Why did E.O. Wilson decide to create his own "mini Krakatoa" in the Florida Keys?

• To study the effects of volcanic eruptions on island ecosystems.

• To test the species-area rule in a controlled environment.

• To observe the natural recolonization of islands after a major disaster.

• To find new species of insects in a remote location.

What was the primary outcome of fumigating the mangrove islands to remove all insects?

• The islands remained barren of insect life for many years.

• The islands were recolonized by a completely different set of species, with no overlap.

• The islands were recolonized by a similar number of species, but with a significant percentage of new species.

• The original species quickly returned, demonstrating resilience to disturbance.

What was a key finding from the Amazon experiment regarding forest fragmentation?

• Smaller forest fragments supported a greater diversity of species due to increased edge effects.

• Forest fragmentation primarily affected smaller, less mobile species.

• Shrinking a habitat had a more significant negative impact on larger animal species.

• Fragmented forests quickly recovered their original biodiversity levels.

What critical realization did biologists and conservationists come to regarding large animal species and protected areas?

• National parks are generally too small to adequately support species with extensive home ranges.

• Smaller animals are more vulnerable to habitat fragmentation than larger ones.

• Human activity has no significant impact on the movement patterns of large wildlife.

• Creating more small, isolated reserves is the most effective conservation strategy.

What is the primary goal of the Yellowstone to Yukon Conservation Initiative (Y2Y)?

• To establish new national parks across North America.

• To connect and protect wildlife habitats from Wyoming to the Yukon.

• To reintroduce endangered species into their native ranges.

• To promote ecotourism in the Rocky Mountains.

Who successfully lobbied for the construction of wildlife crossing structures on Highway 93?

• Local government officials.

• The Confederated Salish and Kootenai Tribes with wildlife biologists.

• Private land developers.

• National park rangers.

What types of structures were built on Highway 93 in Western Montana to help wildlife cross?

• Only overpasses for large animals.

• Only underpasses for small animals.

• A combination of overpasses and underpasses.

• Fences to deter animals from crossing.
