adj biologik
physiological, biochemical changes in organisms connected with natural phenomena and seasons.
ponds used for biological treatment of sewage. Used independently – for treatment by micro-organisms and algae of sinks, saturated with easily oxidizing organic matters, or as the intermediate objects between the industrial treatment facilities and the natural water receivers. They operate by a principle of self-treating of water, accrue sludgy mass which can be used in agriculture as fertilizer or as a raw material for its production.
unwanted, from the human position (see Anthropocentrism), changing of characteristics and qualities of industrial materials, articles, constructions, fodder and food, etc. under the influence of living organisms inhabiting them (destruction of timber by fungi and insects, growing moulds in food-stuff, deconstruction of bricklaying by the roots of plants, etc.).
biological factor preventing from the spreading of these or those species of fauna or their communities (competitiveness, preying, etc.).
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.
a number of various types of biological plants or phenomena and frequency of their meeting on a fixed portion of space and time generally reflecting a complicated form of a living matter, its capacity for self-regulation of functions and resources for its comprehensive usage. B.d. includes all species of animals, plants, fungi and micro-organisms, ecosystems and processes flowing proceeding in them. Three levels of B.d. are outlined: genetic diversity, diversity of species and diversity of ecosystems. Genetic D. reflects the genetic information contained in living matter of the Earth, in a concrete territory, D. of species reflects the amount of species and an opportunity to meet them in a concrete territory. D. of ecosystems reflects the amount of various types of habitats, communities and ecological processes. B.d. is a special case of a universal phenomenon of a diversity of nature.
Decomposition of organic materials by microorganisms.
A maximum tolerance level of lead in human bloodstream can be considered as an example of biological standard. The advantage of a biological standard's application as a controlling tool is a fact that it determines a comprehensive influence of all sources on the researched object, i.e. an object being under the protection. Its disadvantage is a fact that it allows to detect an excess of a maximum tolerance level only when a pollutant has already penetrated into organism and, possibly, in excessive amounts.
a type of ecological monitoring, aimed at controlling over the reaction of living organisms on a pollution of a surrounding environment.
biologik informatika
capability of a community on a basis of usage of matter and energy to reproduce an organic matter. B.p. is usually assessed by biological commodity, net and gross, expressed in weigh measure units per a square measure unit.
Синонимы: bioproductivity См.: Biomass, Biological products of an ecosystem general
penetration into ecosystem and generation in a large number of species alien to it. Pollution by micro-organisms is also called bacteriological or microbiological impurity.
a total increase of biomass of a living matter per a unit of time (usually per a year).
Синонимы: gross
increase of biomass of a living matter less extinct ones per a unit of time (usually per a year).
increase of biomass (phytomass) of autotrophic organisms per a unit of time.
increase of a biomass of heterotrophic organisms per a unit of time.
one of the most applicable methods of water treatment, at which it occurs the mineralization of organic substance by micro-organisms – saprobionts in shallow-water ponds and other reservoirs (see Aerotank, Biofilter).
index of a water contamination by the organic compounds determined by a quantity of oxygen that was taken per a time unit (usually 5 days – BCO5) at the acidification of pollutants contained in a fix volume of water.
amount of organic matter produced in a unit of time per a unit of area by living organisms, included in composition of this or that ecosystem (e.g. kg / hectare per a year). Sometimes is valued by the speed, with which the energy is acquired by organisms (e.g., kkal / m of a living matter per a year).
