Trophic Interactions, Management Trade-Offs and Climate Change: The Need for Adaptive Thresholds to Operationalize Ecosystem Indicators

Abstract

Kadin et al. Adaptive Thresholds for Operational Indicators such as trophic interactions and for trade-offs between management objectives, to enable learning as well as setting target levels or thresholds triggering actions in an adaptive manner. Such flexible strategies make a set of indicators operational over the long-term and facilitate success of EBM.

Appraising the Status of Fish Community Structure in the Yellow Sea Based on an Indicator-Testing Framework

“…Among multiple pressures that impact marine ecosystems, climate change plays one of the most important roles (Barange et al, 2014;Kirkman et al, 2015;Kadin et al, 2019). For instance, climate change was found to be important factor in evaluating the responses of small pelagic fish, an important functional group in marine fish communities, to fishing pressure and decadal variations (Tian et al, 2013;Ma et al, 2018).…”

“…For example, trophic interaction, one of the most typical characteristics of an ecosystem, can modify the responses of ecological indicators to pressures and interfere interpretive ability of indicators to changes in various pressures (Kadin et al, 2019). Efforts have been taken, through comparative multi-model multiecosystem simulation experiments, to explore various ecological indicators to determine whether the ecological indicators selected can track changes in the ecosystems and reveal their emergent properties under multiple pressures (Shin et al, 2018;Fu et al, 2019).…”

Impediments to fisheries recovery in Canada: Policy and institutional constraints on developing management practices compliant with the precautionary approach

“…The observed response to climate change often is not, as simplified here, a direct response, but rather an indirect response to changes in prey or predators. Climate change propagates through the food web and trophic interactions and can modify and mediate the impact of stressors and of the management strategies (Kadin et al 2019). This requires identification of the ecological interaction and quantification of the climate change effect on the interacting species and the interaction itself (e.g., change of density-dependence with warming [Olsen et al 2011]), which remains challenging.…”

Recent advances in management strategy evaluation: introduction to the special issue “Under pressure: addressing fisheries challenges with Management Strategy Evaluation”

“…Additionally, review and perspective articles provide further suggestions for improving communication while enhancing the experience and expertise of stakeholders engaged in the MSE process (Feeney et al 2019;Goethel et al 2019;Miller et al 2019). The articles in the special issue tend to reflect areas of growth in MSE research globally (e.g., Edwards and Dankel 2016;Walsh et al 2018;Pascoe et al 2019;Thorpe and De Oliveira 2019), but many advances on other research fronts are being made that are not directly addressed by these contributions (e.g., better accounting of spatial dynamics in MSE operating models, Punt et al 2016Punt et al , 2017 developing and testing adaptive or empirical management measures, Rätz and Lloret 2018;Plagányi et al 2018; and exploring the impacts of climate change on management performance, Kadin et al 2019).…”
