Which of the following is NOT a factor that can affect the connectivity of a landscape for species movement?

  1. Habitat fragmentation

  2. Habitat loss

  3. Climate change

  4. Species dispersal ability


Correct Option: C
Explanation:

Climate change is a global phenomenon that affects the entire planet, whereas habitat fragmentation, habitat loss, and species dispersal ability are factors that are specific to a particular landscape.

What is the term used to describe the process by which a species moves from one habitat patch to another?

  1. Dispersal

  2. Migration

  3. Colonization

  4. Range expansion


Correct Option: A
Explanation:

Dispersal is the movement of an individual from one habitat patch to another, while migration is the movement of a population from one area to another, colonization is the establishment of a new population in a new area, and range expansion is the increase in the geographic range of a species.

Which of the following is NOT a type of landscape connectivity?

  1. Structural connectivity

  2. Functional connectivity

  3. Perceived connectivity

  4. Genetic connectivity


Correct Option: C
Explanation:

Perceived connectivity is not a type of landscape connectivity. Structural connectivity refers to the physical connectivity of habitat patches, functional connectivity refers to the ability of species to move between habitat patches, and genetic connectivity refers to the flow of genes between populations.

What is the term used to describe the amount of habitat that is available for a species to occupy?

  1. Habitat availability

  2. Habitat suitability

  3. Habitat quality

  4. Habitat fragmentation


Correct Option: A
Explanation:

Habitat availability is the amount of habitat that is available for a species to occupy, while habitat suitability is the degree to which a habitat is able to support a species, habitat quality is the overall condition of a habitat, and habitat fragmentation is the breaking up of a habitat into smaller and smaller patches.

Which of the following is NOT a measure of landscape connectivity?

  1. Effective mesh size

  2. Least-cost path analysis

  3. Circuit theory

  4. Species-area relationship


Correct Option: D
Explanation:

The species-area relationship is not a measure of landscape connectivity. Effective mesh size, least-cost path analysis, and circuit theory are all measures of landscape connectivity.

What is the term used to describe the process by which a landscape becomes more fragmented?

  1. Habitat fragmentation

  2. Habitat loss

  3. Habitat degradation

  4. Habitat conversion


Correct Option: A
Explanation:

Habitat fragmentation is the process by which a landscape becomes more fragmented, while habitat loss is the reduction in the amount of habitat available for a species, habitat degradation is the decline in the quality of a habitat, and habitat conversion is the change of one type of habitat to another.

Which of the following is NOT a consequence of habitat fragmentation?

  1. Reduced species diversity

  2. Increased risk of extinction

  3. Increased genetic diversity

  4. Reduced gene flow


Correct Option: C
Explanation:

Habitat fragmentation can lead to reduced species diversity, increased risk of extinction, and reduced gene flow, but it does not lead to increased genetic diversity.

What is the term used to describe the movement of a species from one area to another in response to changing environmental conditions?

  1. Migration

  2. Dispersal

  3. Colonization

  4. Range expansion


Correct Option: A
Explanation:

Migration is the movement of a species from one area to another in response to changing environmental conditions, while dispersal is the movement of an individual from one habitat patch to another, colonization is the establishment of a new population in a new area, and range expansion is the increase in the geographic range of a species.

Which of the following is NOT a type of landscape management that can be used to improve connectivity for species movement?

  1. Corridor creation

  2. Habitat restoration

  3. Habitat fragmentation

  4. Riparian buffer zones


Correct Option: C
Explanation:

Habitat fragmentation is not a type of landscape management that can be used to improve connectivity for species movement. Corridor creation, habitat restoration, and riparian buffer zones are all types of landscape management that can be used to improve connectivity for species movement.

What is the term used to describe the ability of a species to move through a landscape?

  1. Dispersal ability

  2. Migration ability

  3. Colonization ability

  4. Range expansion ability


Correct Option: A
Explanation:

Dispersal ability is the ability of a species to move through a landscape, while migration ability is the ability of a population to move from one area to another, colonization ability is the ability of a species to establish a new population in a new area, and range expansion ability is the ability of a species to increase its geographic range.

Which of the following is NOT a factor that can affect the dispersal ability of a species?

  1. Body size

  2. Habitat quality

  3. Predation risk

  4. Competition


Correct Option: B
Explanation:

Habitat quality is not a factor that can affect the dispersal ability of a species. Body size, predation risk, and competition are all factors that can affect the dispersal ability of a species.

What is the term used to describe the process by which a species establishes a new population in a new area?

  1. Colonization

  2. Dispersal

  3. Migration

  4. Range expansion


Correct Option: A
Explanation:

Colonization is the process by which a species establishes a new population in a new area, while dispersal is the movement of an individual from one habitat patch to another, migration is the movement of a population from one area to another, and range expansion is the increase in the geographic range of a species.

Which of the following is NOT a type of landscape structure that can affect connectivity for species movement?

  1. Habitat patches

  2. Corridors

  3. Barriers

  4. Matrix


Correct Option: D
Explanation:

The matrix is not a type of landscape structure that can affect connectivity for species movement. Habitat patches, corridors, and barriers are all types of landscape structures that can affect connectivity for species movement.

What is the term used to describe the increase in the geographic range of a species?

  1. Range expansion

  2. Dispersal

  3. Migration

  4. Colonization


Correct Option: A
Explanation:

Range expansion is the increase in the geographic range of a species, while dispersal is the movement of an individual from one habitat patch to another, migration is the movement of a population from one area to another, and colonization is the establishment of a new population in a new area.

Which of the following is NOT a benefit of landscape connectivity for species movement?

  1. Increased genetic diversity

  2. Reduced risk of extinction

  3. Increased species diversity

  4. Reduced gene flow


Correct Option: D
Explanation:

Reduced gene flow is not a benefit of landscape connectivity for species movement. Increased genetic diversity, reduced risk of extinction, and increased species diversity are all benefits of landscape connectivity for species movement.
