Chapter 47, Problem 8TY
Summary Introduction
Introduction:
Biological diversity, biodiversity, is the variations in different species and the ecosystems in which these species survive. Biodiversity is studied in three stages, species diversity, genetic diversity, and ecosystem diversity.

- 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_forwardAlien species invasion has been a threat to biodiversity.

Species Evenness Species evenness takes into account the number of species and the relative abundance of species in a community. Several indices have been proposed. Two of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D). Question 2: What is the Shannon diversity index value for this community? What is the species evenness for this community?arrow_forward
