我们分析了一个一般理论的共存和灭绝的生态群落的随机时间环境波动的影响。结果适用于离散时间(随机差分方程),连续时间(随机微分方程),紧和非紧状态空间和退化或非退化噪声。此外,我们还可以在动力学中包括模拟环境波动、种群结构、生态环境反馈或其他内部或外部因素的辅助变量。我们能够将Benaim和Schreiber(J Math Biol 79:393-431,2019)最近的离散时间结果显著推广到非紧状态空间,并且我们提供了更强的持久性和灭绝结果。Hening和Nguyen(Ann Appl Probab 28(3):1893-1942,2018 a)的连续时间结果被加强,以包括退化噪声和辅助变量。利用一般理论,我们给出了几个例子。在离散时间,我们分类的动态时,有一个或两个物种,并期待在Ricker模型,对数正态分布的后代模型,彩票模型,离散Lotka-Volterra模型以及模型的多年生和一年生生物。对于连续的时间设置,我们探索模型与资源变量,随机复制模型,三维Lotka-Volterra模型。
We analyze a general theory for coexistence and extinction of ecological communities that are influenced by stochastic temporal environmental fluctuations. The results apply to discrete time (stochastic difference equations), continuous time (stochastic differential equations), compact and non-compact state spaces and degenerate or non-degenerate noise. In addition, we can also include in the dynamics auxiliary variables that model environmental fluctuations, population structure, eco-environmental feedbacks or other internal or external factors. We are able to significantly generalize the recent discrete time results by Benaim and Schreiber (J Math Biol 79:393–431, 2019) to non-compact state spaces, and we provide stronger persistence and extinction results. The continuous time results by Hening and Nguyen (Ann Appl Probab 28(3):1893–1942, 2018a) are strengthened to include degenerate noise and auxiliary variables. Using the general theory, we work out several examples. In discrete time, we classify the dynamics when there are one or two species, and look at the Ricker model, Log-normally distributed offspring models, lottery models, discrete Lotka–Volterra models as well as models of perennial and annual organisms. For the continuous time setting we explore models with a resource variable, stochastic replicator models, and three dimensional Lotka–Volterra models.
