Climate warming has caused the seasonal timing of many components of ecological food chains to advance (Thackeray et al. 2010(Thackeray et al. , 2016. In the context of trophic interactions the match-mismatch hypothesis (MMH) postulates that differential shifts can lead to phenological asynchrony with negative impacts for consumers (Cushing 1990). However, it is still largely unresolved whether unequal trophic shifts are adaptive or constrained by
The European eel (Anguilla anguilla) is Critically Endangered under the International Union for Conservation of Nature (IUCN) Red List Categories and Criteria because it has markedly declined in abundance across all life-history stages in much of its natural range. Barriers to migration, such as weirs and sluices, that prevent access to upstream habitat are a key threat to eels in freshwater systems. The impact of these barriers can be partially mitigated by the installation of eel passes that restore migratory pathways. In the Thames River Basin District (Thames RBD), The Zoological Society of London (ZSL) and partners have added traps to monitor eel passes. Further, these organizations have developed a network of citizen scientists and stakeholder organizations that monitor eel movement through the passes. In this paper, we review how data from the Thames European Eel Project enables a better understanding of eel ecology in the Thames RBD and how these data can inform conservation management decisions. In addition, we ask whether stakeholder engagement via citizen science has informed effective conservation action for this species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
