Living organisms and their habitats vary across space and time. Unraveling the mechanisms involved in complex spatial and temporal patterns in nature is one of the most important intellectual challenges in the science of ecology. Remarkable progress has been made in our understanding of how communities are structured, yet major gaps and related challenges remain. Spatial and temporal environmental heterogeneity (resource or non-resource) is widely recognized as a mechanism underlying the structure of ecological communities. To date, work on spatial and temporal heterogeneity has almost exclusively focused on the variance (how much) component. However, similar levels of environmental variation are often structured differently in space (where variation occurs) and time (when variation occurs), likely affecting species distributions and the ways they coexist. There has been limited work on the importance of the spatial and temporal structural components (i.e., covariance or autocorrelation) of environments on the dynamics and patterns of distribution and coexistence of multiple species.

生物体及其栖息地在空间和时间上各不相同。揭示自然界中复杂的空间和时间模式所涉及的机制是生态科学中最重要的智力挑战之一。我们在了解社区的结构方面取得了显著进展，但仍然存在重大差距和相关挑战。时空环境异质性（资源或非资源）被广泛认为是生态群落结构的内在机制。迄今为止，关于空间和时间异质性的工作几乎完全集中在方差（多少）分量上。然而，类似水平的环境变化往往在空间（发生变化的地方）和时间（发生变化的时候）上有不同的结构，可能影响物种分布和它们共存的方式。 关于空间和时间结构成分的重要性的工作有限（即，协方差或自相关）的环境的动态和模式的分布和共存的多个物种。
