diversity inside a habitat or inside a community at a level of species.

an index of diversity at the territorial level, being comparable with landscape, uniting alpha and beta-diversity. The most ordinary index of G.d. is a list of species

constituent element of biological diversity related to assessment of difference between individuals within a population. Individuals can differ by a genotype (including by sex), phenotype, age, by demonstration of modificational, depending on particular environmental conditions, variability etc. Compare. Genotype.

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 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.

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

Radio qabul qilish, bunda tarqalishning turli sharoitlariga bogʻliq holda yuzaga keluvchi kirish signalining turli variantlarini qabul qiladigan, umumiy chiqishga, lekin turlicha kirishlarga ega boʻlgan koʻplab qabul qilgichlardan foydalaniladi; qabul qilgichlar koʻplab umumiy komponentlar orqali kirish signali variantlari oʻrtasida birikish yoki tanlashni chiqish signali iloji boricha tarqalish sharoitlariga bogʻliq boʻlmagan tarzda amalga oshirish uchun hosil qiladilar. Misollar: yoyilgan antennalar vositasida qabul qilish; yoyilgan chastotalar vositasida qabul qilish; yoyilgan qutblanish vositasida qabul qilish.русскийразнесенный прием, Радиоприем, при котором используется совокупность нескольких приемников с общим выходом, но различными входами, принимающими различные варианты входного сигнала, образующиеся в силу различных условий распространения; приемники образуют совокупность посредством многих общих компонентов для осуществления между вариантами входного сигнала сочетания или выбора так, чтобы выходной сигнал был по возможности независим от условий распространения. Примеры: прием посредством разнесенных антенн; прием посредством разнесенных частот; прием посредством разнесенной поляризации.английскийdiversity reception
