The first Marmorkrebs (Decapoda: Astacida: Cambaridae) in Scandinavia [PDF]

BioInvasions Records, 2013
Invasive crayfish have attracted much attention by scientists and policy makers in Europe, partly due to their ability to transmit diseases to native crayfish species. In December 2012, 13 specimens of a new crayfish species were found in the River Marstaan in central Sweden.

On the Fallacy of Color Discrimination: The Rise and Fall of a Rare and Endemic Box Crab (Brachyura: Calappidae)

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Mediterranean Sea is one of the major reservoirs of marine biodiversity and harbors an exceptionally high number of endemic species. Nevertheless, the taxonomic status of many of these endemics still requires confirmation through integrative, modern approaches.

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

Ecological 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 ...

Revealing hidden sources of uncertainty in biodiversity trend assessments

Ecography, 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.

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

Conservation 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.
