Accepted Answer

To maintain the diversity of genes, populations, species, habitats, communities, ecosystems, and landscapes, as well as the processes occurring at each level.

Question 2

Which of the following is NOT one of the five direct drivers of biodiversity loss identified by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)?

Accepted Answer

Natural selection

Question 3

A farmer increases pesticide use to boost crop yields, but soon notices a decline in local bee populations and reduced pollination. Which two drivers of biodiversity loss are most directly illustrated in this scenario?

Accepted Answer

Direct exploitation of organisms and pollution

Question 4

According to the provided data, what percentage of amphibian species are currently threatened with extinction?

Accepted Answer

$$32\%$$

Question 5

Which of the following characteristics is NOT typically associated with conservation biology?

Accepted Answer

Purely theoretical

Question 6

The '30 x 30' target set by the United Nations Convention on Biological Diversity aims to:

Accepted Answer

Ensure that by 2030, at least 30% of terrestrial, inland water, and coastal and marine areas are effectively conserved and managed.

Question 7

Which of the following best explains why conservation biology is considered inherently interdisciplinary?

Accepted Answer

It integrates biological, physical, social sciences, economics, and natural-resource management techniques.

Question 8

Refer to the graph showing human population growth. What major event is most closely associated with the sharp increase in human population size after 1800?

Accepted Answer

The Industrial Revolution

Question 9

A coral reef ecosystem is experiencing a decline in fish populations due to overfishing and increased water pollution. Which two direct drivers of biodiversity loss are most relevant in this case?

Accepted Answer

Direct exploitation of organisms and pollution

Question 10

Which of the following statements about extinction trends is supported by the provided materials?

Accepted Answer

Extinction rates for amphibians have increased more rapidly than for other vertebrate groups.

Question 11

Which of the following is an example of an applied, crisis-oriented approach in conservation biology?

Accepted Answer

Implementing emergency measures to protect a critically endangered species from poaching.

Question 12

If a country wants to meet the '30 x 30' target, and it currently has $$20\% of $$its land and water areas protected, what is the minimum additional percentage it must protect by 2030?

Accepted Answer

$$10\%$$

Question 13

Which of the following is a real-world example of an invasive alien species contributing to biodiversity loss?

Accepted Answer

Introduction of zebra mussels into North American freshwater systems.

Question 14

A conservation biologist is working with local communities to manage a protected area. Which aspect of conservation biology does this best illustrate?

Accepted Answer

Mission-driven and policy-connected

Question 15

Which of the following best explains why amphibians are particularly vulnerable to extinction?

Accepted Answer

They are sensitive to environmental changes such as pollution and habitat loss.

Question 16

Which of the following is a key reason why conservation biology must be continually ongoing?

Accepted Answer

New threats and challenges to biodiversity constantly arise due to human activities and environmental changes.

Question 17

Which of the following is an example of a policy-connected action in conservation biology?

Accepted Answer

Lobbying for the creation of new protected areas based on scientific evidence.

Question 18

If the current rate of extinction for mammals is $$0.5\%$$ per century, and there are 5,000 mammal species, how many species are expected to go extinct in the next 100 years if the rate remains constant?

Accepted Answer

$$25$$

Question 19

Which of the following best illustrates the concept of 'ecologically representative, well-connected and equitably governed systems of protected areas' as described in the '30 x 30' target?

Accepted Answer

Creating a network of protected areas across different habitats, connected by wildlife corridors, and managed with input from indigenous and local communities.
