Technical challenges in the implementation of macroinvertebrate DNA metabarcoding in river biomonitoring: A case study from peninsular Spain—Advantages, limitations and roadmap

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
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 ...

External Abnormalities and Body Deformities of Noble Crayfish (Malacostraca, Astacidae: Astacus astacus) of West Carpathian Massive (Slovakia): Possible Causes for this Phenomenon

open access: yesEkológia (Bratislava), 2022
Astacus astacus (Linnaeus, 1758) is a vulnerable species. Through comprehensive monitoring, we have determined the current spatial distribution of the populations in two streams of the Western Carpathian Massif.

Revealing hidden sources of uncertainty in biodiversity trend assessments

open access: yesEcography, Volume 2025, Issue 5, May 2025.
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.

Crawfishes (Crustacea, Astacidae) of the Soviet Union

open access: yes, 1976
The observations of crawfish behaviour were carried out in artificial water bodies with varying existence conditions. Migration of the western-palearctic Astacidae species to fresh waters in the Ancient Old Pontian Black sea epoch is substantiated.

Global invasion and biosecurity risk from the online trade in ornamental crayfish

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
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.

When Methodological Innovation Changes the Game: A 10‐Year Review of Environmental DNA (eDNA) Applied to Crayfish

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT The use of environmental DNA (eDNA) as a tool for monitoring represents a major innovative advance in environmental science, one that enables the detection of species without the need to observe or capture them. This article assesses the state of play of eDNA research targeting crayfish.
