中文简介: | 考虑了生态系统中种群振荡的稳定性。实验表明,在许多情况下,捕食者-食饵或寄主-寄生虫系统的单斑块动态是容易灭绝的,只有当种群的空间结构通过斑块间的不同步来表达时,才能达到稳定。到目前为止,已经提出了一些机制来解释分散无法使系统同步。我们建议一种分类方案,允许对产生失同步的主进程进行先验(基于系统参数)或后验(基于局部测量)识别。 |
课程简介: | The stability of population oscillations in ecological systems is considered. Experiments suggest that in many cases the single patch dynamics of predator prey or host-parasite systems is extinction prone and stability is achieved only when the spatial structure of the population is expressed via desynchronization between patches. A few mechanisms have been suggested so far to explain the inability of dispersal to synchronize the system. We suggest a classification scheme that allows for either a-priori (based on the system parameters) or a posteriori (based on local measurements) identification of the dominant process that yields desynchronization. |
