相互作用的集合种群研究动态

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.但在很多情况下,种间的相互作用会影响种群的迁移率、灭绝率和侵占率,从而调节相应物种的集合种群动态.这方面的研究主要有集合种群水平上物种之间的竞争、捕食以及在没有任何环境异质性的条件下物种在空间上聚集分布的产生和维持等.综述了近年来关于集合种群水平上的竞争,捕食者和猎物系统以及捕食与复杂空间动态的最新研究成果.

Progresses on the researches of interacting metapopulations

Two or more species can live in the same patch network without any interactions among the respective metapopulations. More interestingly, interspecific interactions might affect the rates of migration, extinction and colonization, in which case interspecific interactions modulate metapopulation dynamics of the species concerned. Related researches are mainly concerned on interspecific competition, predator-prey dynamics and the creation and maintenance of aggregated spatial distributions of species in the absence of any environmental heterogeneity. In this paper, we evaluate progresses on competition, dynamics of predator-prey systems and complex spatial dynamics at the metapopulation level.
