Exam 56: Conservation Biology and Global Change

If all individuals in the last remaining population of a particular bird species were all highly related,which type of diversity would be of greatest concern when planning to keep the species from going extinct? I.genetic diversity II.species diversity III.ecosystem diversity

A land developer and several ecologists are discussing how a parcel of private land should be developed while saving twenty hectares as natural habitat.The land developer suggests that the twenty hectares be divided into twenty separate one-hectare areas.The ecologists suggest that it would be better to have one intact parcel of twenty hectares.What is the significance of these different arrangements of the twenty hectares?

If the nestlings of flycatchers are to benefit from the shift in peak caterpillar season from June 3,1980 to May 15,2000,in which direction should the May 25,2000 peak bird hatching date move?

The main goal of sustainable development is to

How might the extinction of some Pacific Island bats called "flying foxes" threaten the survival of over 75% of the tree species in those islands?

The greatest cause of the biodiversity crisis,the one which includes all of the others,is

Atmospheric carbon dioxide has risen dramatically during the past century.Some global implications of climate change include all the following,with the exception of

Which of the following terms includes all of the others?

Of the following statements about protected areas that have been established to preserve biodiversity,which one is not correct?

If the sex ratio in a population is significantly different from 50:50,then which of the following will always be true?

The primary difference between the small-population approach (S-PA)and the declining-population approach (D-PA)to biodiversity recovery is

We should care about loss in biodiversity in the populations of other species because of

The word triage originated during World War I and was first used by French doctors in prioritizing patients based on the severity of their wounds,because there were more wounded soldiers in need of urgent care than there were resources to treat them.Conservation biologists have to make similar determinations with degraded ecosystems.Which of the following is the most important consideration when it comes to managing for maintenance of biodiversity?

Eutrophication is often caused by excess limiting nutrient runoff from agricultural fields into aquatic ecosystems.This results in massive algal blooms,which eventually die and decompose,ultimately depleting the dissolved oxygen and killing large numbers of fish and other aquatic organism.Predict which of the following human actions would best address the problem of eutrophication near agricultural areas?

Relatively small geographic areas with high concentrations of endemic species and a large number of endangered and threatened species are known as

Some populations of sea turtles and Galápagos tortoises are maintained by people who collect their eggs and hatch/rear the young in captivity.Why is this practice supported by conservationists?

What is the single greatest threat to biodiversity?

Use the following figure to answer the questions below. -Study the information above about quail habitats.Assuming that only one quail can occupy a habitat where all cover requirements are met,what is the maximum number of quail that could inhabit any of the hypothetical plots shown?
