The Archey's frog is a small endangered frog found in the forests off the coast of New Zealand. The frog is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Archey's frog?

• Carrying capacity

• Population bottleneck

• Population overshoot

• Type I survivorship

Which of the following would be categorized as a cultural ecosystem service of forests?

• Recreation and scenic areas for tourism

• Timber and landscape materials

• Mushroom and plant harvests

• Soil stabilization and air purification

Which of the following would most likely result from the deforestation of large areas of forests caused by slash-and-burn agriculture?

• Increased ozone thinning because of the release of CFCs

• Decreased acid rain because of the sequestration of SO2

• Increased global temperature because of the release of CO2

• Deceased evaporation because of the loss of the tree canopy

Based on the theory of island biogeography, which of the following is the most likely reason that an island in the ocean that is 8 kilometers from a continent would have a higher number of species than one that is 20 kilometers from a continent?

• There are more species that have the ability to travel 8 kilometers than can travel 20 kilometers.

• Islands that are closer to continents always have a wider range of habitats than more distant islands do.

• There are smaller populations of each species on islands that are at greater distances from continents.

• Islands that are closer to continents always have more ecological niches than more distant islands do.

Which of the following is a measure of the biodiversity of an ecosystem?

• The total number of individuals of a single animal species

• The density of individuals in a hectare

• The total number of different plant species

• The soil depth at which burrowing insects are located

• The frogs can tolerate a pH between 4.5 and 6.

• The frogs can tolerate a pH between 3.5 and 5.

• The frogs can tolerate any pH less than 4.

For which of the following reasons do small isolated islands have a greater rate of species extinction than larger, less isolated islands?

• Small isolated islands are more likely to receive more migrating species.

• Small isolated islands provide opportunities for a greater diversity of species.

• Because of their size, small isolated islands accumulate more species by chance.

• Small isolated islands have a lower availability of resources.

• Because they have fewer available niches, small isolated islands are targeted and colonized by species.

Which of the following statements about levels of biodiversity is correct?

• Genetic biodiversity is a measure of the total number of genes in a community.

• A narrow distribution of habitats leads to an increase in species diversity.

• Global hotspots are areas where species diversity is thriving due to habitat restoration.

• A population with high genetic biodiversity is better able to respond to environmental stressors.
