摘要

从历史上看,生态系统具有地理边界的想法被认为是naïve和不切实际的。但是,遥感技术的进步使人们能够可靠地探测到空间状况,这些状况似乎为潜在的重大转变提供了早期预警。这就需要重新审视地理边界在解释弹性概念时所起的作用。尽管存在明显的本体论上的不精确,但将生态系统的边界定义为地理上的,而不是动态的(即,作为反馈机制的集合),扩展了对弹性的解释,以提高对偶然因果动力学历史的理解,这些历史最终导致了单一尺度上的紧急自组织。为了证明地理边界的效用,三个相关的讨论将空间弹性理论与岛屿生物地理学理论的要素联系起来:(1)踏脚石作为生态过滤器的功能,(2)移动链接作为拯救效应的例子,以及(3)组合规则和连续平衡映射到自适应循环启发式前向回路的方式。

Geographical boundaries and historical explanations of within-scale resilience

Historically, the idea that ecosystems possess geographical boundaries has been dismissed as both naïve and impractical. But advancements in remote sensing have led to the reliable detection of spatial regimes that seem to provide early warning of a potential critical transition. This invites a reexamination of the role geographical boundaries play in explanations of the resilience concept. Despite apparent ontological imprecision, defining the boundaries of an ecosystem geographically, instead of dynamically (i.e., as collections of feedback mechanisms), dilates explanations of resilience to improve understanding of the history of contingent causal dynamics that culminate in emergent self-organization at a single scale. To demonstrate the utility of geographical boundaries, three related discussions connect spatial resilience theory with elements of island biogeography theory: (1) the function of stepping-stones as ecological filters, (2) mobile links as examples of the rescue effect, and (3) the way assembly rules and successive equilibria map onto the forward loop of the adaptive cycle heuristic.

期刊介绍: Ecological Complexity is an international journal devoted to the publication of high quality, peer-reviewed articles on all aspects of biocomplexity in the environment, theoretical ecology, and special issues on topics of current interest. The scope of the journal is wide and interdisciplinary with an integrated and quantitative approach. The journal particularly encourages submission of papers that integrate natural and social processes at appropriately broad spatio-temporal scales. Ecological Complexity will publish research into the following areas: • All aspects of biocomplexity in the environment and theoretical ecology • Ecosystems and biospheres as complex adaptive systems • Self-organization of spatially extended ecosystems • Emergent properties and structures of complex ecosystems • Ecological pattern formation in space and time • The role of biophysical constraints and evolutionary attractors on species assemblages • Ecological scaling (scale invariance, scale covariance and across scale dynamics), allometry, and hierarchy theory • Ecological topology and networks • Studies towards an ecology of complex systems • Complex systems approaches for the study of dynamic human-environment interactions • Using knowledge of nonlinear phenomena to better guide policy development for adaptation strategies and mitigation to environmental change • New tools and methods for studying ecological complexity
