  population niche
The population niche was broader in the wet season in terms of both prey size and taxa.
      
The structure of the population niche for both biomass and reproductive output was found to be quite different on the two gradients.
      
In path B, individual niche widths are reduced, while the population niche width remains constant.
      
Nonadaptive population niche expansion is also possible, resulting from selectively neutral diet changes or introgression.
      


The pole ordering of the species with space niche (horizontal and vertical) and time niche is as follows: the community of field rats from Zhongjiang, Sichuan, consists of two demes and one peripheral species. The first deme is formed from A. agrarius plus M. musculus living in almost every corner of field becouse of broad adaption, but their popula- tion peak and feeding time in a day are different. That is the foundation of them living in a same niche. The second deme is R. norvegicus plus R. niviventer that...

The pole ordering of the species with space niche (horizontal and vertical) and time niche is as follows: the community of field rats from Zhongjiang, Sichuan, consists of two demes and one peripheral species. The first deme is formed from A. agrarius plus M. musculus living in almost every corner of field becouse of broad adaption, but their popula- tion peak and feeding time in a day are different. That is the foundation of them living in a same niche. The second deme is R. norvegicus plus R. niviventer that belongs to middle type of body, their biology is diff- erent from one another with population peak, feeding time and their un- ique territory that makes them share one niche. R. niviventer is a peri- pheral species of the community that usually lives in hill fields of lone- ly place feeding on corn, cotton, wheat and so on with unique niche se- parate from other two demes. The difference of niche of different spec- ies in one community is great advantage to share limit resources, to reduce cotention among species that are benefit to population increasing.

利用三维生态位资料进行PO排序。结果表明,四川省中江县农田害鼠群落由两个集群和一个边缘种组成。第一集群为黑线姬鼠加小家鼠,分布广,适应性强,二者因发生高峰期和取食时间的差异而集聚共存,占领同一生态位;第二集群为褐家鼠加大足鼠,属中型鼠类,由于二者栖息地的异域性,取食时间和发生高峰期的差异而聚集成群;社鼠为群落的边缘种,主要分布在坡地、草丛,以旱粮作物为主食,独占一个生态位。由于群落中种群生态位的差异,不仅可以更充分有效地利用资源,而且可以减小种间竞争,利于物种自身的繁衍。

Through investigating and analyzing on natural regeneration conditions of manchurian ash (Fraxinus mandshurica) in the plantation of korean pine(Pinus koraiensis), mongolian scots pine (Pinus sylvestris var mongolica) and dahurian larch (Larix gmelini), the happening and developing characters of manchurian ash population are studied as follows: (1) The manchurian ash population can occur ia the artificial coniferous communities where there are seed source trees in the extent of 70m apart from plantation edge...

Through investigating and analyzing on natural regeneration conditions of manchurian ash (Fraxinus mandshurica) in the plantation of korean pine(Pinus koraiensis), mongolian scots pine (Pinus sylvestris var mongolica) and dahurian larch (Larix gmelini), the happening and developing characters of manchurian ash population are studied as follows: (1) The manchurian ash population can occur ia the artificial coniferous communities where there are seed source trees in the extent of 70m apart from plantation edge and sufficient soil moisture in the plantation. (2) The age and space distribution patterns and tree height increment of the manchurian ash population in the artificial coniferous communities are reasonable and normally growing, and it can go up to the canopy as well as forms natural and artificial mixed broadleaf-coniferous forest community. The niche of manchurian ash natural regeneration population in the artificial coniferous communities is also discussed.

通过对水曲柳(Fraxinus mandshurica)在红松(Pinus koraiensis)、樟子松(Pinus sylvestris Var.mongolica)、落叶松(Larix gmelini)人工林下的天然更新状况的调查分析,对其种群在人工针叶群落下发生发展特点做了比较详细的讨论。(1)在土壤水分条件比较适中的人工针叶群落中,只要在70m范围内有水曲柳种源存在,就能发生水曲柳天然更新种群。(2)现实人工针叶群落中天然发生的水曲柳种群年龄结构、空间结构(包括垂直分层和水平分布)及高生长状况都比较合理,能正常生长发育,进入主林层,与上层林木共同构成人工天然针阔混交林。此外,还对人工针叶群落中水曲柳天然更新种群生态位做了分析和讨论。

in this papet, the niche breadth and niche overlap of tree populations of Carpinus pubescens community in karst mountain of Guiyang were measured by using Levin's formula and Wanggang's improved formula respectively.The niche relationships of the populations and their influence on the structure and dynamics of the community were analysed.
