Refers to the size of cells in a raster dataset at the current map scale. May range from low (>1000 m) to moderate (200-500 m) and high (0.5-25 m) and adequate resolution depends on the objectives of the study and on the scale of the analysis.

A defined time period when spawning occurs.

A group of organisms all of which have a high degree of physical and genetic similarity, generally interbreed only among themselves, and show persistent differences from members of allied groups of organisms.

Also "species diversity"; the number of species that occurs in an area. Seealso Biodiversity.
