WebThe biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species. Appearance isn't everything Organisms may appear to be alike and be different species. WebThrough bioindicators, scientists need to observe only the single indicating species to check on the environment rather than monitor the whole community. [7] Small sets of indicator species can also be used to predict species richness for multiple taxonomic groups. [8]
