  realized niche
aripo uses differences in volatile blends released by infested cassava plant parts and restricts its fundamental niche to a realized niche, which enables coexistence with its competitor T.
      
The realized niche is influenced by local biotic processes that influence species behaviour and the shape of the response curves relative to environmental gradients.
      
We investigated the ecological behaviour (the response to environmental factors in the field, synonymous to the term realized niche) of four closely related species pairs (Melica nutans, M.
      
Variation in those species with wide ecological amplitudes, particularly in populations near the boundary of the realized niche, is likely to be particularly revealing.
      
The index summarizes many traits of the realized niche of the fish.

The implications of fundamental and realized niche proposed by Hutchi-nson in 1957 are discussed.Species realized niche will never overlap based on hisdefinition,contracting with that in the realistic environmental array.To remedvthe confusion in using the concepts of fundamental and realized niche,we sug-gest that these two notions should be defined for a species or a species population individually.A species fundamental niche will not be cenfined in a particularcommunity but in its areal or even in some hypothesized environmental characte-ristic combination which allows the species to survive and reproduce,i.e.,funda-mental niche is determined by the species physiological tolerance or requirements.It should be an entity or hypervolume in the n-dimensional niche space.A speciesrealized niche is described as the environmental characteristic combinations thatsurround a species population in a particular community.In the niche space,it ismanifold.Another new concept,niche center,is defined as the point or a compart-ment where the species response is optimal within the niche space.When a speciesdistribution is ignored or the species has a homogenous distribution within the a-vailable compartments of the compartmentalized niche space,the point defined iscalled its theoretical niche center.Usually species disstribution is uneven andthe point defined is called its realized niche center.The distance froma species rea-lized center to theoretical niche center is defined as its niche deviation.And thedegree of a speices niche hypervolume diffuse within the niche space is describedwith the niche diffusion index.Formulae are proposed for such metrics and anexample from a south China subtropical evergreen forest community is presented.

本文对n 维超体积生态位定义作了进一步的阐明.物种的“基础生态位”为其分布区的环境参数及其生理学容忍性和要求所决定,而“实现生态位”则为该物种种群在某一特定群落生境中所处的环境参数所确定.一物种的生态位中心点为该物种在生态位空间中具最佳适应的位置.进而根据是否在测度中考虑进物种分布参数,而分别称为理论与实现生态位中心点.以广东鼎湖山厚壳桂(Cryptocarya)群落在利用土壤营养方面为例,说明物种生态位中心点等指数的测度.

In this paper,the relationship between niche overlap and interspecific competition of two species was discussed on the basis of niche theory. Interspecific competition didn't take place where the realized niches of both species did overlap.

Founoamental niche and realized niche of dominant populations in the foorest scondary sere in Mt.Jinyun was reported,concerning four communities in 1986 and 1996.The result shows:realized niche concerns the resource application capacity of species in a special resource state,and fundamental niche focuses on the ecological amplitude of species.In the secondary sere of forest in Mt.Jinyun,different specieds has varing niche breadth:the maximal realized niche breadth of forest pioneer species is smaller than that of climaxal species,however,it is the reverse case for fundamental niche breadth.

通过1986年和1996年对缙云山森林次生演替序列中四种群落类型的重复调查,用两种公式计测生态位宽度,研究演替序列优势种群的基础生态位和实际生态位.结果表明,实际生态位侧重于物种对特定资源的利用能力,基础生态位侧重于物种的生态幅度.在缙云山森林次生演替序列中,各个优势种群的生态位宽度不同,森林先锋种的最宽实际生态位比演替顶极种窄,基础生态位则相反
