Community isolation drives lower fish biomass and species richness, but higher functional evenness, in a river metacommunity

“…Standing stock is a variable easy to record and represents the combined effect of ecosystem processes related to biomass productivity. Consequently, it is currently used for capturing ecosystem functioning among different taxa and environments (Adler et al., 2011; Brose & Hillebrand, 2016; Duffy et al., 2016; Maureaud et al., 2019, 2020; Piñeiro‐Guerra, Fagúndez‐Pachón, Oesterheld, & Arim, 2014; Tilman et al., 1997). Standing stock represents the cumulative effect of productivity but could also be affected by dead rate for example by consumption (Altieri, Trussell, Ewanchuk, Bernatchez, & Bracken, 2009).…”

“…The present study focuses on the empirical evaluation of the effect of community isolation on the biodiversity and functioning of a riverine metacommunity. Biodiversity was represented by taxonomic and functional fish diversity, and ecosystem functioning by standing stock of fish biomass (following Brose & Hillebrand, 2016; Duffy, Lefcheck, Stuart‐Smith, Navarrete, & Edgar, 2016; Maureaud, Andersen, Zhang, & Lindegren, 2020; Maureaud et al., 2019). To this end, the theoretical framework previously introduced is summarised as a general hypothesis (i.e.…”

Disentangling temporal food web dynamics facilitates understanding of ecosystem functioning

“…dispersal and invasion, population dynamics or climate variability etc.) (Maureaud et al 2020). Along these lines, it should be carefully considered, a priori as well as a posteriori, whether the observed empirical changes are related to alterations in species composition, community structure, dominance patterns, energetic fluxes, or a combination of these.…”

Opportunities to improve ecosystem‐based fisheries management by recognizing and overcoming path dependency and cognitive bias

“…Indicator‐based approaches are becoming increasingly feasible means of dealing with scale and complexity as empirical understanding is defining clearer thresholds for judging performance and system‐level risk—for example the ecosystem‐wide indicators and production–biomass relationships (Libralato et al., 2019; Link et al., 2015; Link & Watson, 2019; Maureaud et al., 2019; Ye & Carocci, 2019). An indicator species approach is another multispecies/ecosystem management method in use.…”
