Ecological tolerance - capacity of an organsm to tolerate 
unfovarable environmental impacts.
Ekologik xavfsizlik - tabiiy muhit va aholi salomatligiga xavf 
xatar yetgazmaydigan holat. E. x. atrof muhitga salbiy 
amntropogen ta’simi kamaytirishga yo’naltirilgan tadbirlar 
majmuini amalga oshirish orqali erishiladi.
Safety ecological - the position, at which there is no threat of 
damaging the natural environment and health of the population.
S. e. is reached by complex o f measures, directed on a decrease 
o f negative anthropogenous environmental impact.
Ekologik ekspertiza [lot. “expertus” - tajribali] - taklif 
etilayotgan loyihaning atrof-muhitga ko’rsatiladigan ta ’sir 
oqibatlarining oldini olish maqsadida uning ta’sir samarasini 
oldindan aniqlashga qaratilgan faoliyat.
Ecological expertise - [lat. “expertus” - experienced] - an 
activity on eliciting and forecasting of effects of assumed 
project’s impact with the purpose o f extenuation of consequences 
of environment impact.
Ekologiya - [yun. “oikos” - uy, joy va logos - ta’limot, so’z] — 
E. Gekkelning ta’riflashicha, biologiyaning organizmlar bilan 
muhitning uzaro munosabatlarini o ’rganuvchi bir bo’limi (auto- 
ekologiya va sin-ekologiya). E. barcha tirik organizmlar va 
muhitni hayot uchun qulay qiladigan barcha jarayonlami 
o’rganadi.
Ecology - [ greek “oikos” - home, place and “logos” - doctrine, 
word] - according to E. Hekkel, a biranch of a biological science 
about relationships between organisms and environment (auto 
ecology and synecology). E. studies all living organisms and all 
functional processes making environment suitable for life.

EKOLOGIYA
Ekotizim - A. Tensli tomonidan kiritiigan bo’lib, u tarkibidagi 
organizm va anorganik omillar teng xuquqli komponentlar 
bo’lmish denamik muvozanatdagi nisbatan barqaror tizimni 
ifodalaydi. Boshqacha qilib aytganda, tirik mavjudodlar 
jamoalari va ularning yashash muhitini o’z ichiga qamrab olgan 
funksional tizimga ekotizm deyiladi.
Ecosystem - a concept, introduced by A. Tensly, meaning a 
rather stable system of dynamic equilibrium, in which organisms 
and inorganic factors are full components. In other words, E. 
represents organisms, jointly operating on a section, and their 
communities interacting with environment.
Ekotsid - [yun. “oikos” - uy, vatan va lot, “caedere” - o’ldirish]- 
hayot muhitini atayin barbod qilish, bu esa yalpi biosetga olib 
keladi.
Ecocide - [greek “oikos” - home, motherland and latin “caedere”
- to kill] deliberate killing of a habitats resulting an biocide. 
Endem — [yun. “endemos”- mahalliy] — faqat aynan shu 
mintaqada yashaydigan biologik tur.
Endemic - [greek “endemos” - domestic] biological species 
living only in a given region.
Q irilib borayotgan tu rla r - biologik hususiyatlar hozirgi zamon 
tabiiy yoki inson tomonidan o’zgartirilgan yashash sharoitlarga 
mos kelmaydigan, ularga moslashish qobilayati esa tugab-bitgan 
turlar (qar. adaptatsiya). Q.b.t insonning ko’magisiz halokatga 
mahkum. Odatda Q.b.t qizil kitoblarga kiritiladi; ularga nisbatan 
maxsus chora tadbirlar ko’riladi. Yana qarang yo’q bo’lib 
ketayotgan tur.
Extincting species - species, biological features of which do not 
correspond to the modem natural or changed by person 
conditions of existence, and capacity of adapting to them (see

Adapting) are exhausted. Without a targated support by a man E. 
s. are doomed on loss. As a rule, E.s. are regietered in the red 
books; in relation to them special measures on protection are 
established. See also Endangered species.
