Biodiversity Conservation And Wild Life Question 15
Question: Which of the following is not a concern regarding habitat fragmentation?
Options:
A) Habitats can change type.
B) Habitats can be too small to support some species.
C) It reduces dispersal ability of some animals.
D) It creates a large amount of vulnerable edge habitat.

Answer:
Correct Answer: A
Solution:
The correct answer is indeed A) Habitats can change type. Here’s why:
A) Habitats can change type: This is not typically a direct concern of habitat fragmentation. While habitat fragmentation can indirectly lead to changes in habitat type over time (for example, due to changes in microclimate or the invasion of different species), the immediate concern of habitat fragmentation is the division of large, continuous habitats into smaller, isolated patches.
B) Habitats can be too small to support some species: This is a major concern of habitat fragmentation. Smaller habitat patches may not be large enough to support viable populations of some species, particularly those that require large territories.
C) It reduces dispersal ability of some animals: This is another major concern of habitat fragmentation. When habitats are fragmented, it can be more difficult for animals to move between patches, which can reduce gene flow and lead to more isolated (and therefore more vulnerable) populations.
D) It creates a large amount of vulnerable edge habitat: This is also a concern of habitat fragmentation. The creation of more “edge” habitat can expose species to predators and other threats that they are not well-adapted to cope with.
So, while all these factors are related to habitat fragmentation, the one that is not a direct concern is A) Habitats can change type.
It’s important to note that habitat fragmentation is a major threat to biodiversity and can have complex and far-reaching impacts on ecosystems.
Therefore, efforts to prevent and mitigate habitat fragmentation are crucial for conservation.
