Species richness - correct answer -the number of different
species in a community
Species evenness - correct answer -relative abundance of each
species
Species diversity - correct answer -The number and relative
abundance of species in a biological community. Combines
species richness AND species evenness (within a community).
Biodiversity - correct answer -the diversity of important
ecological entities
That span multiple spatial scales: genes to species to
Communities

Rank Abundance Curve - correct answer -a curve that plots the
relative abundance of each species in rank order from the most
abundant to the least abundant species
Species Accumulation Curve - correct answer -graph that plots
species richness as a function of the sampling effort (total number
of individuals that have been sampled). Eventually, sampling
more individuals adds few or no new species.
Community differences in species accumulation - correct answer
-some need much greater sampling effort to estimate the overall
species richness. (Richness of soil bacteria so high, each sample
was a new species)
Species composition - correct answer -actual identity of the
species present in the
Community
Shannon Index of diversity - correct answer -(Bowman 4ed.
