Name two common biodiversity metrics used in mammal communities.

• A. Biomass density and trophic level.
• B. Body mass and metabolic rate.
• C. Species richness and evenness.
• D. Habitat area and patchiness.

Answer: (C)

In ecology, measuring biodiversity in a mammal community boils down to counting species and looking at how many individuals belong to each species. The best two metrics are species richness, which is simply how many different species are present, and evenness, which describes how evenly the individuals are distributed among those species. Together, they capture both the variety of life and the balance of abundances, giving a clear picture of a community’s biodiversity. A place with many species but one dominant species has high richness but low evenness, while a community where species are more equally represented has high evenness and a richer sense of balance. The other options focus on energy flow, biological traits, or landscape structure rather than direct measures of species diversity.
