Sentence examples for richness population from inspiring English sources

Allelic richness, population size, and toad presence/absence were primarily associated with terrestrial habitat variables, including pond density and vegetative characteristics reflecting surrounding land use (e.g. presence of woodlands, hedgerows, extent of area in livestock [sheep] pasture, and anthropogenic development).

We also derived a novel measure of mammal conservation importance for each site based on a "Mammalian Conservation Priority index" (MPi) which incorporates information on species richness, population abundance, body size distribution, conservation status, and forest patch area.

Existence of viable habitat is critical to the survival of any species, so habitat fragmentation is the main reason for the changes in distribution and abundance of organisms, and is usually considered to have negative effect on the abundance, species richness and population of organisms in a specific landscape.
