To elucidate the changes in the spatial and seasonal origins of SOM in a eutrophic lake, we collected sediment at 31 sampling points in Lake Hachiro, northern Japan, in June and November of 2016 and April and June of 2017, and measured total organic carbon...
How do ecological resilience metrics relate to community stability and collapse?
###RSS_DATE###
Publication date: December 2019Source: Ecological Indicators, Volume 107Author(s): Caleb P. Roberts, Dirac Twidwell, David G. Angeler, Craig R. AllenAbstractThe concept of ecological resilience (the amount of disturbance a system can absorb before collapsing and reorganizing) holds potential for predicting community change and collapse—increasingly common issues in the Anthropocene. Yet neither the predictions nor metrics of resilience have received rigorous testing. The cross-scale resilience model, a leading operationalization of resilience, proposes resilience can be quantified by the...
