In ecology, it is often used to quantify the biodiversity of a habitat. It takes into account the number of species present, as well as the abundance of each species. .

How does temporal variability influence productivity (local scale)? . Species distribution. Density . and size are useful measures for characterizing populations. Scientists gain additional insight into a species' biology and ecology from studying how individuals are spatially distributed. Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Patterns are often characteristic of a particular species; they depend on local environmental conditions and the species' growth characteristics (as for plants) or behavior (as for animals)..

Define one of the following: alpha diversity, beta diversity, gamma diversity. A. FRESHWATER ON EARTH. 70% of Earth is covered in water.. 3% of Earth’s water is freshwater (97% saltwater). FRESHWATER CONTAINS LESS THAN 1% SALT. 68.7% of FRESHWATER is frozen in glaciers and icecaps.
