This study evaluates the opportunities and challenges of using DNA metabarcoding of river macroinvertebrates for routine ecological status assessment under the EU Water Framework Directive. By reanalysing data from rivers in north‐west Spain, it identifies key sources of false positives and negatives, compares bulk and eDNA sampling with traditional ...

Revealing hidden sources of uncertainty in biodiversity trend assessments
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Global invasion and biosecurity risk from the online trade in ornamental crayfish
Abstract Trade in undomesticated ornamental animals has rapidly expanded beyond brick‐and‐mortar retail stores to now include growing numbers of internet marketplaces. The growing volume, diversity, and origins of invasive non‐native species in trade challenge already weak national biosecurity policies.

Molt and gastroliths in Austropotamobius pallipes (Lereboullet, 1858) [PDF]
Knowledge of the molting cycle in crayfish may contribute (1) to improving a population analysis for monitoring and conservation purposes and (2) to imposing significant constraints on practices involved in culture.

Age, growth, and trophic ecology of the Redeye Bass, an alien invader of California rivers
Abstract Objective The Redeye Bass Micropterus coosae is a piscivore introduced into California, which has become a threat to the state's endemic freshwater fishes. It has eliminated native fishes from the middle reaches of the Cosumnes River, our study stream, which is the largest stream without a major dam on its main stem in the Sacramento–San ...
