Question

exploring measures of biodiversity
the scientists used two measures of biodiversity in their study - species richness and species evenness. the shannon wiener index takes into account both of these measures. for example, consider the two hypothetical parks below, a and b.

park a

park b

both parks have the same number of individuals and both have four species represented (deer, raccoons, opossum, and squirrels). but do the two parks have the same level of biodiversity?
no, because park b has more species richness
no, because park b has more species evenness
yes, because park b has more species evenness
yes, because park b has more species richness

Explanation:

Species richness is the number of different species in an area, and both parks have the same number of species. Species evenness is the relative abundance of each species. Park B appears to have a more even distribution of the four - species compared to Park A. Biodiversity is measured by both richness and evenness. Since they have the same richness but Park B has more evenness, they do not have the same level of biodiversity.

Answer:

No, because Park B has more species evenness
