The species is the fundamental category of taxonomic classification, ranking below a genus or subgenus. Species names are represent...
Three different areas of criticism of the biological species concept are considered: 1. The impracticability of the criterion of reproductive isolation. The demand for more practical criteria is rejected, because reproductive isolation is seen as the factor that produces and maintains species as ...

Biodiversity(生物多样性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each other in some way, bi...

At higher-latitude sites with small temperature gradients, depth-dependent increases inCremin(Fig.3) may be disproportionately influenced by vertical gradients in particle characteristics (for example, substrate availability), ecological shifts (community) and/or physiological changes (exo-enzymes to match...
