Early warning indicators in aquatic ecosystems

In this post Craig Allen and Hannah Birge discuss a paper from Sarah Burthe and colleagues ‘Do early warning indicators consistently predict nonlinear change in long-term ecological data?’ Complex systems of humans and nature rarely change in gradual, expected ways. Instead, changes often occur suddenly, with major, non-linear losses of human and ecological capital. Once these unexpected changes occur, it can be difficult to restore … Continue reading Early warning indicators in aquatic ecosystems

How network analyses can help to find out what happens to ostrich farming after an avian influenza outbreak

In this post Craig Allen and Hannah Birge discuss a paper from Christine Moore, John Grewar and Graeme S. Cumming ‘Quantifying network resilience: comparison before and after a major perturbation shows strengths and limitations of network metrics’ Humans are very good at creating mental models to simplify nature’s complexity, to make its many parts and interactions more understandable. Approaches that exemplify this include hierarchy theory, panarchy … Continue reading How network analyses can help to find out what happens to ostrich farming after an avian influenza outbreak

Resilience: buzzword or quantifiable theory with management application?

In this post, David Angeler discusses a paper he recently handled by Kirsty Nash and colleagues “Herbivore cross-scale redundancy supports response diversity and promotes coral reef resilience” This paper will appear as part of a forthcoming special profile ‘Quantifying Resilience’ in Journal of Applied Ecology. We are living in a time of spurious certitude. The unprecedented transformation of the biosphere is shown by rapid changes … Continue reading Resilience: buzzword or quantifiable theory with management application?
