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 C. It can lead to dampened oscillations within patches D. Both A and B E. Both B and C

Which of the following is/are considered an effect of fragmentation as opposed to an effect of habitat loss? Choose all that apply. A Animals situated in new edge habitat are disrupted and fail to develop. B Newly separated patches have insufficient prey animals to support a predator species. C Animal populations on either side of a new barrier become inbred.

Habitat fragmentation can lead to: a)The disappearance of the matrix due to decreased habitat heterogeneity b) Changes in patch use by animals, with smaller patches leading increased size of home range or movement for many animals c) Variation in microenvironment near the edge of the patch with negative consequences for diversity
As a habitat patch gets smaller, it $a$. cannot support populations of species that require large areas. $b$. supports only small populations of many species. $c .$ is influenced to an increasing degree by edge effects. $d$. is invaded by species from surrounding habitats. $e .$ All of the above
