Ecological structures and processes occur at specific spatiotemporal scales, interactions that across multiple scales mediate scale-specific (e.g., individual, community, local, or regional) responses to disturbance. Despite the importance of scale, explicitly incorporating a multi-scale perspective into research management actions remains challenge. The discontinuity hypothesis provides fertile avenue for addressing this problem by linking measureable proxies inherent structure within...
The adaptive cycle and its extension to panarchy (nested cycles) has been a useful metaphor conceptual model for understanding long-term dynamics of change in ecological social–ecological systems. We argue that cycles are ubiquitous complex systems because they reflect endogenously generated as result processes self-organization evolution. synthesize work from wide array fields support this claim. If growth, conservation, collapse renewal endogenous systems, then there ought be signals...
Summary Human impacts on the environment are multifaceted and can occur across distinct spatiotemporal scales. Ecological responses to environmental change therefore difficult predict, entail large degrees of uncertainty. Such uncertainty requires robust tools for management sustain ecosystem goods services maintain resilient ecosystems. We propose an approach based discontinuity theory that accounts patterns processes at spatial temporal scales, inherent property ecological systems....
Research on early warning indicators has generally focused assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional boundary detection procedures that result in ecoregion maps are typically based ecological potential (i.e. vegetation), and often fail account for ongoing changes due stressors such as land use change climate their effects plant animal communities. We Fisher information, an information theory-based method, both...
Abstract: The cross‐scale resilience model states that ecological is generated in part from the distribution of functions within and across scales a system. Resilience measure system's ability to remain organized around particular set mutually reinforcing processes structures, known as regime. We define scale geographic extent over which process operates frequency with occurs. Species can be categorized into functional groups are link between ecosystem structures resilience. applied avian...
Communities of organisms, from mammals to microorganisms, have discontinuous distributions body size. This pattern size structuring is a conservative trait community organization and product processes that occur at multiple spatial temporal scales. In this study, we assessed whether patterns serve as an indicator threshold between alternative regimes. Over the past 7000 years, biological communities Foy Lake (Montana, USA) undergone major regime shift owing climate change. We used...

The cross-scale resilience model was developed in ecology to explain the emergence of from distribution ecological functions within and across scales, as a tool assess resilience. We propose that underlying discontinuity hypothesis are relevant other complex adaptive systems, can be used identify track changes system parameters related theory behind model, review cases where it has been applied non-ecological discuss some examples social-ecological, archaeological/ anthropological, economic...
Habitat structure across multiple spatial and temporal scales has been proposed as a key driver of body size distributions for associated communities. Thus, understanding the relationship between habitat is fundamental to developing predictions regarding influence change on animal Much work assessing focused terrestrial taxa with determinate growth, primarily analysed discontinuities (gaps) in distribution species mean sizes (species relationships or SSRs). The suitability this approach...
Science is increasingly a collaborative pursuit. Although the modern scientific enterprise owes much to individuals working at core of their field, humanity confronted by highly complex problems that require integration variety disciplinary and methodological expertise. In 2016, U.S. National Foundation launched an initiative prioritizing support for convergence research as means “solving vexing problems, in particular, focusing on societal needs.” We discuss our understanding objectives...
Abstract The cross‐scale resilience model suggests that system‐level ecological emerges from the distribution of species’ functions within and across spatial temporal scales a system. It has provided quantitative method for calculating given system so been valuable contribution to largely qualitative field. As it is currently laid out, accounts at which environmental resources species are present functional roles play but does not inform us about how much resource or function provided. In...
Abstract The distribution of pattern across scales has predictive power in the analysis complex systems. Discontinuity approaches remain a fruitful avenue research quest for quantitative measures resilience because discontinuity provides an objective means identifying systems and facilitates delineation hierarchical patterns processes, structure, resources. However, current methods have been considered too subjective, complicated opaque, or become computationally obsolete; given ubiquity...
Given the intensity and frequency of environmental change, linked cross-scale nature social-ecological systems, proliferation big data, methods that can help synthesize complex system behavior over a geographical area are great value. Fisher information evaluates order in data has been established as robust effective tool for capturing changes dynamics, including detection regimes regime shifts. Methods developed to compute accommodate multivariate various types requires no priori decisions...
Abstract Aim Our understanding of and ability to predict species declines is limited, despite decades study. We sought expand our within a regional landscape by testing models using both traditional hypotheses those derived from complex adaptive systems approach. Location study area was the dry mixed grassland south‐eastern Alberta, Canada, one largest remnants native in North America, adjacent Saskatchewan. Methods used breeding birds test relationship between suite traits associated with...
Major scientific breakthroughs are generally the result of materializing creative ideas, an inductive process that sometimes spontaneously and unexpectedly generates a link between thoughts and/or objects did not exist before. Creativity is cornerstone thinking, but scientists in academia judged by metrics quantification often leave little room for thinking. In many fields, reductionist approaches rewarded new ideas viewed skeptically. As result, inquiry confined to narrow safe disciplinary...
