Shifting gears for the use of the shifting baseline syndrome in ecological restoration
(MDPI AG, 2019)
There are two barriers to accomplishing restoration of ecosystems: insufficient information about historical baselines to guide restoration, and shifts between the actual baselines and perceptions about historical conditions. ...
To tip or not to tip: The Window of Tipping Point Analysis for social-ecological systems
(Wiley, 2022)
We introduce six steps to define a “Window of Tipping Point Analysis” which serves as a framework to increase the understanding of processes and tipping points in social-ecological systems. We apply the Window of Tipping ...
Toward conceptual cohesiveness: A historical analysis of the theory and utility of ecological boundaries and transition zones
(2007)
Ecological transition zones are increasingly recognized as systems that play a critical role in controlling or modifying flows of organisms, materials, and energy across landscapes. Many concepts describing transitional ...
Identification of ecologically relevant species for ecological risk assessment: A proposal from theoretical ecology Identifi cación de especies ecológicamente relevantes para la Evaluación de Riesgo Ecológico: Una propuesta desde la ecología teórica
(2013)
Based on recent advances in ecological network theory, we present an ad hoc conceptual framework and a methodological proposal for the evaluation of the ecological relevance of species within a community, oriented towards ...
