Species richness quantifies the amount of money each species is valued at on the biodiversity stock exchange the relative abundance of species in a community. the number of species in a community the combination of the number of species in a community and their relative abundances
Match each term to the best definition or description. Resiliency Species richness Biodiversity Gamma diversity I I I I :: Number of species in an environment. :: Considers number of habitats and total species number among them. :: Combination of species richness and species evenness :: Same as species evenness. High probability of recovery to original state. High probability of disruption.
The competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.

Ecology and Biology: Shannon Diversity Index: Definition & Example The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community. Denoted as H, this index is calculated as: H = -Σpi * ln(pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species. The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species What is the Shannon diversity index value for this community? What…
