Synergies Between Anthropogenic Litter and Biopollution in SW Bay of Biscay Rivers Discovered Through Citizen Science: Implications for Conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.
ABSTRACT Anthropogenic litter and other pollutants are known to contribute to the introduction and settlement of invasive alien species (IAS) in marine settings; however, the relationship between biopollutant IAS and litter in rivers is much less studied.

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 ...

Rapid Establishment and Impact Assessment of the Redclaw Crayfish (Cherax quadricarinatus) Invasion in the Kruger National Park, South Africa

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Amidst the rapid degradation of the environment, protected areas act as a buffer for sensitive species against drivers of change. The Kruger National Park, in the Zambezian Lowveld Freshwater Ecoregion, encompasses two critical transboundary river basins, which are threatened by overexploitation, climate change and nonnative invasive species ...

Prioritising Non‐Native Crayfish Species for Management in the Rhine‐Main Observatory Using the Dispersal‐Origin‐Status‐Impact (DOSI) Scheme

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Managing non‐native species remains a critical challenge in biodiversity conservation, highlighting the need for effective prioritisation frameworks that integrate ecological, economic and policy considerations. Given that biological invasions are a population‐level rather than a species‐level phenomenon, more nuanced assessment schemes are ...

Mapping 15 years of crayfish plague in the Iberian Peninsula: The impact of two invasive species on the endangered native crayfish.

open access: yesPLoS ONE, 2019
Crayfish plague, caused by the pathogen Aphanomyces astaci, is one of the main factors responsible for the decimation of the native European crayfish species Austropotamobius pallipes. In Spain, two North American freshwater crayfish species, Procambarus

A COMPARISON OF SURVIVAL AND GROWTH IN JUVENILE ASTACUS LEPTODACTYLUS (ESCH.) AND PACIFASTACUS LENIUSCULUS (DANA) UNDER CONTROLLED CONDITIONS

open access: yesKnowledge and Management of Aquatic Ecosystems, 2006
The aim of this study was to compare survival and growth of juvenile narrow-clawed crayfish (Astacus leptodactylus) and signal crayfish (Pacifastacus leniusculus) fed only with experimental pellets (45% of proteins, 6% of fat, 20% crude fibre) under ...
