集合种群的似Allee效应

Allee - like Effects in Metapopulation

可是，大多数的研究集中在局域种群水平上的Allee效应，而关于集合种群水平上的似Allee效应的研究却很有限。

However , most researches focus on Allee effects at local population level , while research on Allee-like effects at metapopulation level still remains so limited .

运用Leslie矩阵和Markov链建立了一个具年龄结构的集合种群随时间动态变化的空间分布模型，给出了集合种群持续存在以及灭绝的条件。

The spatial distributed models with age-constructed metapopulation dynamics are established by applying Leslie matrix and Markov chain . The conditions of sustainable existence and extinct of metapopulation are studied .

在捕食者-猎物集合种群模型中，我们看到似Allee效应对捕食者的影响更为强烈。

In the model of predator-prey on metapopulation level , Allee-like effects influence predators more intensively .

该物种主要通过重力和动物传播种子，居群间的基因流有限，形成了典型的集合种群（metapopulation）结构。

Oryza granulata scatters seeds mainly by gravity and animals , causing limited scale of gene flow between local populations and attaining a typical metapopulation structure of the distributional pattern .

Levins于1969年最早提出集合种群这一概念，用来指由生活在离散斑块中的不稳定的种群组成的种群。

In 1969 , Levins put forward the concept of metapopulation to describe the population made up of unstable populations living in fragmented patches .

已有的研究表明，如果局域种群中存在Allee效应，则在集合种群水平上将出现似Allee效应（Zhou&Wang2004）。

Studies show that if there is Allee effects at local population level , an Allee-like effects may arise at the metapopulation level ( Zhou & Wang 2004 ) .

把Allee效应引入两个物种在集合种群水平上的抽彩式竞争系统，用相平面分析法和模拟研究了模型的动态行为。

In this paper , the Allee-like effect is introduced into a metapopulation model of two-species ( symmetric ) competition . Phase plane analysis and simulation was used to investigate the dynamics of the models .

在集合种群似然竞争模型中，不同形式的似Allee效应会有不同的影响，总体看来似Allee效应是其不稳定因子。

In the model of apparent competition on metapopulation level , different forms of Allee-like effects may influence the system differently . All in all , Allee-like effects is an unstable factor for the ecological system .

本研究利用常微分动力系统以及基于网格模型的元胞自动机模型对Allee效应、拥挤效应以及捕食作用集合种群的空间分布模式做了全面的模拟研究。

In this paper , I discuss and simulate the influences of Allee effect , overcrowding effect and predation effect on the spatial distribution of metapopulation by cellular automata based on lattice model and ordinary differential equations .

本文是在徐彩琳和Tilman研究工作的基础上，将竞争系数引入集合种群动力模式，建立了集合种群之间竞争的数学模型，并对5-集合种群的竞争动态进行了计算机模拟研究。

Based on Xu Cai-ling and Tilman 's research works , the paper establishes the mathematical model of the competition among metapopulations by integrating competition coefficient in the kinetic model of aggregate populations , and simulates the dynamic competition among five aggregate populations on computer .

用空间直观模型是否足以从斑块占据性资料中推断集合种群的动态过程？（英文）

Are patch occupancy data sufficient for inferring metapopulation dynamics using spatially explicit patch occupancy models ?

生态位宽度变窄会减少集合种群的数量从而增加其灭绝风险；

The narrowing of niche breadth can decrease the metapopulation size and thereby increase the extinction risk .

生境规模大小尺度不是决定集合种群演化的决定性因素。

The size of the habitat was not the decisive factor to the evolution of the metapopulation .

在集合种群水平上，两个或更多物种可以生活在同一个斑块网络中而没有相互作用。

Two or more species can live in the same patch network without any interactions among the respective metapopulations .

在反复经历局域种群灭绝和再侵占的集合种群中，每个局域种群将会拥有一个年龄属性。

In a metapopulation with recurrent local extinction and recolonization , every deme will have a " age " property .
