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).

- Bob Davison describes the Endangered Species Act (ESA) as an effective tool for conserving biological diversity. What is his rationale for the value of focusing on individual species? The public is not concerned about the economic costs of individual species recovery. A focus on individual species is cheaper than protecting entire ecosystems. Establishing public empathy for charismatic species provides an opportunity to educate people about lesser-known species. The public tends to value intact ecosystems over particular plant and animal species.arrow_forwardDiscuss the role of disturbances in moderating species diversity with relation to succession and the Intermediate Disturbance Hypothesis. 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_forwardExplain about information gap of Adaptation of species to changes in the environment ( livestock )arrow_forward
- Is 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_forwardDescribe and give example of Behavioural in Adaptation and Speciationarrow_forwardPlease answer questions from 1 to 10 1) compare species diversity and genetic diversity 2) list several reasons to value biodiversity 3) how does the green house effect occur? 4) identify the primary causes of modern species extinction 5) describe how pesticides, such as DDT, undergo the process of biological magnification 6) choose a species that might be affected by global warming, and predict how that species might be affected 7) contrast conservation biology with restoration biology 8) explain why reserves protect biodiversity 9) explain causes and affects of acid rain 10) give an account of the factors that threaten biodiversityarrow_forward
- Explain how resource partitioning involving ecological character displacement can ease competition between coexisting species.arrow_forwardList five factors that can determine whether an equilibrium population is in danger of extinction.arrow_forwardDescribe a hypothetical three community with high species richness but low species evennessarrow_forward
- One example of coevolution is when speciation within one group of organisms drives speciation within another group of organisms with which it interacts. The term for this type of coevolution is which of the following? Mutualism Antagonism Cospeciation Cooperation Conflictarrow_forwardData shown in this figure describes the species richness of mammals and birds among a variety of Sky islands. Which of the following best fits the correlations represented in the graphs? 1) number of individuals increases with area and decreases with isolation 2) species richness increases with area and decreases with isolation 3) species diversity varies depending on area and isolation? Follow up question which model of species distribution and abundance does this data support? 1) Species area relationship 2) species accumulation curve 3) island-biogeography 4) rapoport’s rulearrow_forwardDescribe two interspecific interactions where both species benefit and both species are at a disadvantage.
