Question 1

A strategy to preserve biodiversity with several small reserves versus one large reserve would be effective if _________
A) Species are evenly distributed across the entire area
B) If species are distributed about the area in a heterogeneous manner
C) The area is dominated by species with very large home ranges
D) The region is very homogeneous

Accepted Answer

Several small reserves can be effective in preserving biodiversity if the species are distributed about the area in a heterogeneous manner. This approach can help protect a variety of habitats and minimize the risk of losing species due to a single catastrophic event. However, if the species are evenly distributed across the entire area or if the region is very homogeneous, a large reserve may be more effective in preserving biodiversity. Similarly, if the area is dominated by species with very large home ranges, a large reserve may be necessary to provide enough habitat for these species to thrive.

Question 2

The results of a study of southern dunlin in Sweden showed that _______.
A) As the population declined, mating pairs found individuals with rare alleles
B) As time progressed, the population size recovered
C) The offspring of mated close relatives were less likely to hatch
D) More eggs hatched from more closely related mating pairs than less closely related mating pairs.

Accepted Answer

The study found that the offspring of mated close relatives were less likely to hatch. This suggests that inbreeding depression was present in the population. The other answer choices are not supported by the information given in the question.

Question 3

Agricultural land where synthesized nitrogen fertilizer is used impacts ecosystem services because _______________.
A) It allows for more crops produced per acre
B) There are compromises to high quality water that would otherwise be used for drinking and recreation
C) There are increases to species richness
D) There are improvements to the provisioning of water for drinking and recreation

Accepted Answer

The use of synthesized nitrogen fertilizer in agricultural land may lead to compromises in high quality water that would otherwise be used for drinking and recreation. This can have negative impacts on ecosystem services such as water provisioning and recreational value of ecosystems.

Question 4

A no-take zone in a marine protected area specifically:
A) Still allows for fishing
B) Allows only for commercial fishing
C) Attempts to protect the area from human disturbance
D) Attempts to protect the area from land-based pollution

Accepted Answer

The answer of A no-take zone in a marine protected...

Question 5

A(n)_________ would be a function or attribute provided in support of human interests by ecosystems.Generally,it saves a cost that would otherwise have to be paid.
A) Net primary product
B) Ecosystem service
C) Regulatory service
D) Economical service

Accepted Answer

Ecosystem service refers to the functions and benefits provided by ecosystems that support human well-being, such as air and water purification, pollination, and nutrient cycling. These services are often essential for economic activities and save costs that would otherwise have to be paid. Net primary product refers to the amount of organic matter produced by plants, while regulatory service refers to the regulation of ecosystem processes such as climate and water flow. Economical service is not a commonly used term in ecology.

Question 6

A marine protected area is ___________.
A) All marine with no adjacent land area included
B) All or mostly marine area, sometimes with portions of adjacent land
C) All pelagic area
D) Only coastal areas with no deep sea space

Accepted Answer

A marine protected area (MPA) is typically an all or mostly marine area that is protected by law or other effective means to conserve biodiversity, manage natural resources, and promote ecosystem services. While MPAs may include portions of adjacent land (such as beaches, rocky intertidal zones, or wetlands), the focus is on protecting and managing the marine environment. MPAs can encompass a range of habitats and ecosystems, from nearshore coral reefs to open ocean waters.

Question 7

There is often a _______________ between agriculture production and biodiversity.
A) Tradeoff
B) Direct positive relationship
C) Complementary relationship
D) Synergistic relationship

Accepted Answer

Agriculture production often involves practices that can decrease biodiversity, such as clearing natural habitats, using pesticides and monoculture practices. In order to maximize yields and profitability, farmers may prioritize this production over conservation efforts. As a result, there is often a tradeoff between agriculture production and biodiversity conservation.

Question 8

Irreplaceability to a conservation biologist would mean _______.
A) A measure of how much biodiversity is lost each year as a result of climate change
B) A value of how many rare plants and animals exist in a given area
C) A relative measurement of how important an area of land is for achieving regional conservation targets
D) How many individuals within a population have rare alleles that cannot be replaced

Accepted Answer

Irreplaceability refers to how important a specific area is for achieving conservation targets. It measures the unique contribution of an area to conservation efforts and assesses the potential loss if that area is not protected. It is a relative measurement and takes into account factors such as the rarity of species, ecosystem services, and threats faced by the area.

Question 9

The effectiveness of a marine protected area (MPA)may be limited by _____________.
A) The amount of regional nitrogen pollution
B) Global climate change
C) Overharvesting of marine species
D) All of the above

Accepted Answer

Marine protected areas can only be effective if they are properly managed and protected from multiple threats, including regional nitrogen pollution, global climate change, and overharvesting of marine species. All of these factors can limit the effectiveness of MPAs in protecting and conserving marine ecosystems. Therefore, choice D is the best answer.

Question 10

With regard to the size of a marine protected area (MPA),you would expect a MPA that is 50% of the size of an adjacent MPA to be __________ at protecting a fish population.
A) Less effective
B) More effective
C) Just as effective as a larger MPA
D) 50% less effective

Accepted Answer

The effectiveness of a marine protected area (MPA) in protecting a fish population generally increases with its size. A smaller MPA, such as one that is 50% the size of an adjacent MPA, would typically be less effective due to factors like smaller habitat coverage and potentially higher edge effects, where fishing pressure can be more intense just outside the boundaries.

Question 11

Protected areas such as _________,are large unmodified or slightly modified areas,that retain their natural character and influence without permanent or significant human habitation,that are protected and managed to preserve their natural condition,but also provide a foundation for environmentally and culturally compatible,spiritual,scientific,educational,recreational,and visitor opportunities.
A) Wilderness areas
B) National parks
C) Natural monuments
D) Strict nature reserves

Accepted Answer

The answer of Protected areas such as _________,are large unmodified...
