explain how species diversity promotes adaptation and survival in changing environments.
Which of the following statements is/are consistent with the Intermediate
disturbance hypothesis?
Species diversity is maximized in areas that experience high levels of disturbance
Areas with low levels of disturbance will be dominated by K selected species
Decades of suppression in California has likely increased diversity in our national forests
Areas with intermediate levels of disturbance will have the lowest levels of diversity
Using the community assembly theory, provide a framework or explanation on: How do some exotic species outperform locally-adapted native species? Cite specific example(s).

You may refer to the disturbances and species diversity diagram in your discussion, and explain some of the key characteristics of r-selected and k-selected species that lead to these observed patterns.arrow_forward
- 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 diversityarrow_forwardIs it possible that some species function together as an integrated, holistic community, whereas other species at the same locality behave more individualistically? If so, what factors might determine which species function in which way?arrow_forwardCompare and contrast species scale vs. system scale goals for conserving both mutualist biodiversity and mutualist ecosystem function. Give a real world example in which one of these approaches is used for mutualism conservation and explain its strengths and weaknesses with respect to conserving mutualism.arrow_forward
