What is the term used to describe the variety of roles and functions performed by different species within an ecosystem?

  1. Functional diversity

  2. Species richness

  3. Genetic diversity

  4. Ecological niche


Correct Option: A
Explanation:

Functional diversity refers to the range of functions and roles played by different species within an ecosystem.

Which of the following is NOT a component of functional diversity?

  1. Species richness

  2. Species composition

  3. Functional traits

  4. Genetic diversity


Correct Option: D
Explanation:

Genetic diversity refers to the variation in genetic characteristics within a population or species, while functional diversity focuses on the variety of functions and roles played by different species in an ecosystem.

Why is functional diversity important in forestry?

  1. It enhances ecosystem resilience.

  2. It increases timber production.

  3. It reduces the risk of pests and diseases.

  4. All of the above


Correct Option: D
Explanation:

Functional diversity contributes to ecosystem resilience by providing a buffer against environmental changes, increases timber production by optimizing resource utilization, and reduces the risk of pests and diseases by promoting diverse defense mechanisms.

Which of the following is NOT a functional trait commonly measured in forestry?

  1. Leaf area index

  2. Wood density

  3. Nitrogen fixation ability

  4. Pollination efficiency


Correct Option: D
Explanation:

Pollination efficiency is not typically measured as a functional trait in forestry, as it is more relevant to ecological studies of plant-pollinator interactions.

How can forest management practices promote functional diversity?

  1. Planting a variety of tree species

  2. Encouraging natural regeneration

  3. Maintaining deadwood and decaying logs

  4. All of the above


Correct Option: D
Explanation:

Planting a variety of tree species increases species richness and functional diversity, encouraging natural regeneration allows for the establishment of diverse plant communities, and maintaining deadwood and decaying logs provides habitat for a variety of organisms, contributing to functional diversity.

Which of the following is NOT a potential consequence of reduced functional diversity in forests?

  1. Increased vulnerability to climate change

  2. Reduced resistance to pests and diseases

  3. Decreased nutrient cycling

  4. Increased carbon sequestration


Correct Option: D
Explanation:

Reduced functional diversity can lead to decreased nutrient cycling and increased vulnerability to climate change and pests and diseases, but it does not directly affect carbon sequestration.

What is the term used to describe the process of selecting and planting tree species based on their functional traits?

  1. Functional trait-based forestry

  2. Precision forestry

  3. Silviculture

  4. Agroforestry


Correct Option: A
Explanation:

Functional trait-based forestry involves selecting and planting tree species based on their functional traits to achieve specific ecosystem functions or services.

Which of the following is NOT an example of a functional trait that can be used in functional trait-based forestry?

  1. Leaf area index

  2. Wood density

  3. Nitrogen fixation ability

  4. Tree height


Correct Option: D
Explanation:

Tree height is a structural trait rather than a functional trait. Functional traits are those that directly influence an organism's ecological role or function.

How can functional diversity contribute to the provision of ecosystem services in forests?

  1. By enhancing nutrient cycling

  2. By increasing water infiltration and storage

  3. By supporting a diversity of wildlife habitats

  4. All of the above


Correct Option: D
Explanation:

Functional diversity contributes to ecosystem services by enhancing nutrient cycling, increasing water infiltration and storage, supporting a diversity of wildlife habitats, and providing other benefits.

Which of the following is NOT a potential challenge in implementing functional trait-based forestry?

  1. Lack of data on functional traits

  2. Difficulty in measuring functional traits

  3. Trade-offs between different functional traits

  4. All of the above


Correct Option: D
Explanation:

Implementing functional trait-based forestry can be challenging due to lack of data on functional traits, difficulty in measuring functional traits, and trade-offs between different functional traits.

What is the term used to describe the process of managing forests to maintain or enhance functional diversity?

  1. Functional diversity management

  2. Ecosystem-based forest management

  3. Sustainable forest management

  4. Biodiversity conservation


Correct Option: A
Explanation:

Functional diversity management involves managing forests specifically to maintain or enhance functional diversity.

Which of the following is NOT a potential benefit of functional diversity management in forests?

  1. Increased resilience to climate change

  2. Enhanced productivity

  3. Reduced risk of pests and diseases

  4. Increased carbon emissions


Correct Option: D
Explanation:

Functional diversity management aims to maintain or enhance functional diversity, which can lead to increased resilience to climate change, enhanced productivity, and reduced risk of pests and diseases. It does not directly lead to increased carbon emissions.

How can functional diversity be assessed in forests?

  1. By measuring functional traits of individual species

  2. By calculating functional diversity indices

  3. By analyzing species composition and abundance data

  4. All of the above


Correct Option: D
Explanation:

Functional diversity can be assessed by measuring functional traits of individual species, calculating functional diversity indices, and analyzing species composition and abundance data.

Which of the following is NOT a common functional diversity index?

  1. Shannon diversity index

  2. Simpson diversity index

  3. Rao's quadratic entropy

  4. Functional richness


Correct Option: A
Explanation:

The Shannon diversity index is a measure of species diversity that does not take into account functional traits. Rao's quadratic entropy and functional richness are common functional diversity indices.

What is the term used to describe the process of using functional diversity to predict ecosystem functioning?

  1. Functional trait-based modeling

  2. Ecosystem modeling

  3. Biodiversity-ecosystem functioning research

  4. Ecological forecasting


Correct Option: A
Explanation:

Functional trait-based modeling involves using functional diversity to predict ecosystem functioning.
