What is the term used to describe the changes that occur at the boundary between two different habitats?

  1. Edge effect

  2. Habitat fragmentation

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge effect refers to the changes in abiotic and biotic conditions that occur at the boundary between two different habitats.

Which of the following is NOT a common edge effect?

  1. Increased light penetration

  2. Increased wind speed

  3. Increased predation

  4. Increased species diversity


Correct Option: D
Explanation:

Edge effects typically lead to a decrease in species diversity, as some species are unable to adapt to the changed conditions.

What is the main cause of edge effects?

  1. Habitat fragmentation

  2. Climate change

  3. Pollution

  4. Invasive species


Correct Option: A
Explanation:

Edge effects are primarily caused by habitat fragmentation, which is the process of breaking up a continuous habitat into smaller, isolated patches.

Which of the following is NOT a negative consequence of edge effects?

  1. Increased predation

  2. Increased competition

  3. Increased disease transmission

  4. Increased genetic diversity


Correct Option: D
Explanation:

Edge effects can have both positive and negative consequences. Increased genetic diversity is generally considered a positive consequence, as it can help populations to adapt to changing environmental conditions.

What is the term used to describe the process by which edge effects gradually diminish with increasing distance from the edge?

  1. Edge attenuation

  2. Habitat recovery

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge attenuation refers to the process by which edge effects gradually diminish with increasing distance from the edge.

Which of the following factors can influence the magnitude of edge effects?

  1. Habitat type

  2. Fragment size

  3. Edge shape

  4. All of the above


Correct Option: D
Explanation:

The magnitude of edge effects can be influenced by a variety of factors, including habitat type, fragment size, and edge shape.

What is the term used to describe the process by which species that are adapted to edge habitats become more abundant?

  1. Edge specialization

  2. Habitat selection

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge specialization refers to the process by which species that are adapted to edge habitats become more abundant.

Which of the following is NOT an example of an edge-adapted species?

  1. White-tailed deer

  2. Gray squirrel

  3. Red-eyed vireo

  4. American robin


Correct Option: D
Explanation:

White-tailed deer, gray squirrel, and red-eyed vireo are all examples of edge-adapted species. American robin is not typically considered an edge-adapted species.

What is the term used to describe the movement of species between edge habitats and interior habitats?

  1. Edge permeability

  2. Habitat connectivity

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge permeability refers to the movement of species between edge habitats and interior habitats.

Which of the following factors can affect edge permeability?

  1. Habitat type

  2. Fragment size

  3. Edge shape

  4. All of the above


Correct Option: D
Explanation:

Edge permeability can be affected by a variety of factors, including habitat type, fragment size, and edge shape.

What is the term used to describe the process by which edge effects can lead to the extinction of species?

  1. Edge-induced extinction

  2. Habitat loss

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge-induced extinction refers to the process by which edge effects can lead to the extinction of species.

Which of the following is NOT a factor that can contribute to edge-induced extinction?

  1. Increased predation

  2. Increased competition

  3. Increased disease transmission

  4. Increased habitat availability


Correct Option: D
Explanation:

Increased habitat availability is not a factor that can contribute to edge-induced extinction.

What is the term used to describe the management of edge effects?

  1. Edge management

  2. Habitat restoration

  3. Ecological succession

  4. Species turnover


Correct Option: A
Explanation:

Edge management refers to the management of edge effects to minimize their negative impacts on biodiversity.

Which of the following is NOT a common edge management technique?

  1. Buffer strips

  2. Edge feathering

  3. Habitat corridors

  4. Edge burning


Correct Option: D
Explanation:

Edge burning is not a common edge management technique.

What is the goal of edge management?

  1. To minimize negative edge effects

  2. To increase habitat availability

  3. To promote ecological succession

  4. To increase species turnover


Correct Option: A
Explanation:

The goal of edge management is to minimize the negative impacts of edge effects on biodiversity.
