a number of species in a given community or in a given area. There are distinguished .Alpha – diversity (a number of species in a considered biotope), beta – diversity (a number of species in all biotopes of a given area) and gamma-diversity.

a finite aggregate quantity of organisms, closed by its relation to a successful reproduction of postery in any bisexual combination of species.

biological species, inhabiting spare territories free of biocenosises of a natural or anthropogenic origin among the first.

organism which was brought and naturalized in area where it had never inhabited earlier.

species or other taxonomic unit that recently was considered as fading, infrequent or vulnerable but a number of which has been retrieved by now and due protection is provided.

usually under B.s. or simply species it is understood a population, or variety of populations, of species which are able to crossbreed forming a fecund produce (without reduction of fertility) possessing a number of common morphophisiological features and detached from other alike groups of species with almost entire absence of the hybrid forms. B.s. is a basic structural unit in a system of living organisms, a qualitative stage of evolution. In context of Obliganto asexual (agamic), parthenogenetic and self-impregnating organisms under B.s. there are understood groups of alike clones (produces of one organism) or lines possessing a genetic and morpho-physiological analogy, occupying a certain areal and having a similar type of interrelations with habitat.

finite aggregate of organisms, meeting genetic and/or taxonomic definition of the species and similarly related to resources and conditions of environment (of similar specialization and ecological niche).

species, biological features of which do not correspond to the modern natural or changed by person conditions of existence, and capacity of adapting to them (see Adapting) are exhausted. Without a targeted support by a man E.s. are doomed on loss. As a rule, E.s. are registered in the Red books; in relation to them special measures on protection are established. See also Endangered species.

species or other taxonomic unit which is under a threat of diminishing or survival of which is impossible unless the threat causing factors are eliminated.

characteristic of a community determined either by relative, or absolute number of species.

proportion between a number of species and any index of significance: number, biomass, productivity, etc.

a biological species, deliberate damaging of its individuals (collecting, herbariums, killing, entrapment, etc.) and a disturbance of a habitat of which is prohibited by the appropriate legislation, moral norms and customs.
