Section 5.4 questions

. Scientists hope to decrease the incidence of white nose syndrome (WNS) in populations of bats in a fairly unpopulated region of the northeast United States. Which of these approaches would be most likely to result in decreasing WNS?

Capture the bats and bring all of them to live into a laboratory setting while treating WNS.

Close more isolated bat caves, forcing all bats to roost in more accessible caves, where they can be more easily treated.

Bring as many bats as possible into zoos and wildlife refuges, where they will have more contact with other species and less contact with other bats.

Prevent tourists from entering bat caves, and allow in only scientists with sterilized clothes and equipment.

. A new disease among endangered geese is found. What is the best, first step scientists could take to find its origin?

Map the genome of the disease.

Test humans to see if this is a case of zoonosis.

Determine if this is a disease also found in domestic geese.

Look in museum specimens for a likely "case zero".

. Endangered black-footed ferrets are threatened by disease. Each of the following may help manage this problem except

Increasing densities of the ferrets in their populations

Preventing habitat destruction so that they are no forced into smaller areas

Keeping black-footed ferrets away from other species in the zoos where they are being bred for reintroduction

Identifying environmental factors that may stress the ferrets
