Answer:
Correct Answer: C
Solution:
The correct answer is C) Movement corridors . . . population fragmentation.
Here’s why:
Movement corridors are areas of habitat that connect wildlife populations separated by human activities or structures (such as roads, development, or logging).
These corridors facilitate the movement of organisms across fragmented habitats, allowing them to mix, mate, and increase genetic diversity, which is crucial for the survival of many species.
On the other hand, population fragmentation refers to the division of large, continuous populations into smaller, isolated ones due to habitat fragmentation.
This can lead to a decrease in genetic diversity and increase the risk of extinction for those isolated populations.
So, by enhancing movement corridors, wildlife managers can help reduce population fragmentation, thereby aiding in the conservation of endangered species.
This strategy helps maintain biodiversity by ensuring that individuals from different populations can interact and breed, preventing the negative effects of inbreeding and genetic drift in small, isolated populations.
The other options (A, B, and D) do not accurately represent strategies used by wildlife managers to conserve endangered populations. For instance, population fragmentation and biological magnification are generally harmful and are not things that conservationists would want to enhance.
Similarly, source habitats are areas where a species originates, and while protecting these is important, biological magnification (the increasing concentration of toxic substances within each successive link in the food chain) is not something that would typically be reduced in this context. Hence, these options are not correct.
