The biological entities are almost always species and the organismal scope typically a taxon but potentially also an ecologically or functionally defined grouping (e.g. ‘water birds’ or ‘trees’) or other operational unit (e.g. genes). The list would typically contain multiple entities, but may be as short as a single entity or, if a sampling effort focused on a certain taxon yielded no results, even contain none.
