Which negative effect can habitat fragmentation have on a metapopulation? A. It can make patches smaller, thus increasing patch extinction rate B. It can make patches more isolated, thus decreasing patch colonization rate O C. It. can lead to dampened oscillations within patches D. Both A and B E. Both B and C

The long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US. However only 5 million acres now remain causing major declines in the Gopher tortoise population. Given this, what is expected to happen to overall diversity of species that depend on Gopher Tortoise burrows?a. increaseb. decreasec. stay the same

Islands are well known for having many endemic (unique) species. What is a likely explanation for this pattern? O A. The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate. O B. Colonizers encounter fewer competitors on an island, so they can diversify. O C. Islands are more complex habitats than continents are, so they have more niches for specializations. O D. Humans bring partly or fully domesticated species with them when they arrive on islands. O E. Colonizers are likely to have more diversity than local populations and thus outcompete them. «< Question A Moving to another question will save this response.

d. community 20. How can geography lead to reproductive isolation? a. Some populations may have a milder habi tat than other populations. b. Subspecies may choose to occupy different areas for competitive reasons. c. Extremes of temperatures may reduce the breeding opportunities for some. d. A physical barrier may arise and separate a population, preventing interbreeding. lluminate Education M Inc.
