Ecosystem Size Predicts Social-Ecological Dynamics, Mark A. Kaemingk, Christopher J. Chizinski, Craig R. Allen, Kevin L. Pope

Recreational fisheries are complex adaptive systems that are inherently difficult to manage because of heterogeneous user groups (consumptive vs. nonconsumptive) that use patchily distributed resources on the landscape (lakes, rivers, coastlines). There is a need to identify which system components can effectively predict and be used to manage nonlinear and cross-scale dynamics within these systems. We examine how ecosystem size or water body size can be used to explain complicated and elusive angler-resource dynamics in recreational fisheries. Water body size determined angler behavior among 48 Nebraska, U.S.A. water bodies during an 11- year study. Angler behavior was often unique and …

1. Recreational fisheries are traditionally managed at local scales, but more effective management could be achieved using a cross-scale approach. To do this, we must first understand how local processes scale up to influence landscape patterns between anglers and resources. We highlight how population-based synchrony methods, used in conjunction with a complex-adaptive-systems framework, can reveal emergent spatial properties within social-ecological systems such as recreational fisheries.

2. Herein, we quantified the level of spatial synchrony in angler behaviour, defined the relationship between angler synchrony and distance among waterbodies, and highlighted social-ecological attributes contributing to these patterns. We leveraged a 111 waterbody-year …

Transdisciplinary Application Of Cross-Scale Resilience, Shana M. Sundstrom, David G. Angeler, Ahjond S. Garmestani, Jorge-H. Garcia, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The cross-scale resilience model was developed in ecology to explain the emergence of resilience from the distribution of ecological functions within and across scales, and as a tool to assess resilience. We propose that the model and the underlying discontinuity hypothesis are relevant to other complex adaptive systems, and can be used to identify and track changes in system parameters related to resilience. We explain the theory behind the cross-scale resilience model, review the cases where it has been applied to non-ecological systems, and discuss some examples of social-ecological, archaeological/ anthropological, and economic systems where a cross-scale resilience analysis could …
