Metacommunity ecology has the potential to inform such programs, because it combines dispersal processes with niche-based approaches and recognizes variability in community composition. Using intermittent rivers prevalent and highly dynamic ecosystems that sometimes dry we develop a conceptual model to illustrate how dispersal limitation and flow intermittence influence the performance of biological indices. We produce a methodological framework integrating physical- and organismal-based dispersal measurements into predictive modeling, to inform development of dynamic ecological quality assessments. Such metacommunity-based approaches could be extended to other ecosystems and are required to underpin our capacity to monitor and protect ecosystems threatened under future environmental changes. cc by-nc (c) Cid et al., 2020 http://creativecommons.org/licenses/by-nc/3.0/es/ info:eu-repo/semantics/openAccess Canvi climàtic Biologia d'aigua dolça Ecosistemes Climatic change Freshwater biology Biotic communities A Metacommunity Approach to Improve Biological Assessments in Highly Dynamic Freshwater Ecosystems info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
