Species abundance, typically, the sum total of individuals from a given species within a given area. A species is considered abundant when it has a high population relative to the size of the area it inhabits.
Figure 1 shows how having multiple species present in a plant community can stabilize ecosystem processes if species vary in their responses to environmental fluctuations such that an increased...

23 wrz 2016 · Species diversity is a term used to define the different number of species in an area (Species richness) and its abundance and the distribution of these species in that ecosystem. It’s a measure of the variety in the ecosystem.
Species richness, the count, or total number, of unique species within a given biological community, ecosystem, biome, or other defined area. While species richness does not consider the population sizes of individual species in the area (see species abundance) or how even the distribution of each.
Species abundance is the number of individuals per species, and relative abundance refers to the evenness of distribution of individuals among species in a community. Two communities may be equally rich in species but differ in relative abundance.
31 gru 2016 · Distribution, abundance, and species richness are the fundamental state variables in ecology. Surprisingly, though, they are simply derived quantities of a more fundamental quantity, a point ...
