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.

Phylogeny of Austropotamobius pallipes (Lereboullet, 1858) based on the analysis of 16S and COI mitochondrial DNA markers [PDF]

, 2009
Filogenetski odnosi unutar populacija slatkovodnih rakova vrste Austropotamobius pallipes (Lereboullet, 1858) još nisu u potpunosti razjašnjeni. Novija istraživanja ukazuju na postojanje vrste-kompleksa, odnosno postojanje dva ili više taksona u okviru ...

Going to the archives: Combining palaeoecological and contemporary data to support river restoration appraisals

River Research and Applications, Volume 41, Issue 1, Page 23-36, January 2025.
Abstract River restoration practices are being increasingly implemented to help offset the global degradation of freshwater ecosystems. The ecological success of such projects is typically determined via post‐project appraisals comparing restored conditions against specified baselines (e.g., pre‐project and/or non‐restored data), but such approaches ...

The first record of translocated white-clawed crayfish from the Austropotamobius pallipes complex in Sardinia (Italy)

Journal of Limnology, 2015
The white-clawed crayfish Austropotamobius pallipes complex is native to Europe, being present in 18 European countries, Italy included. However, the number and abundance of its populations are today restricted and it has been recently classified as ...

The native crayfish Austropotamobius pallipes complex in the Foreste Casentinesi National Park (Central Italy): conservation status and threats

The European Zoological Journal
The white-clawed crayfish Austropotamobius pallipes complex populations are declining in Italy, mainly due to habitat alteration, invasive alien species and pollution.

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

Aquatic 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.

Distribution and ecology ofAustropotamobius pallipesin Germany [PDF]

Bulletin Français de la Pêche et de la Pisciculture, 1997
In Germany, three species of native freshwater crayfish are found : the noble crayfish (Astacus astacus), the stone crayfish (Austropotamobius torrentium) and the white-clawed crayfish (Austropotamobius pallipes), which occurs very rarely. The distribution of white-clawed crayfish (A.

Evaluating the eDNA spatial signal in natural populations and its application for the monitoring of the threatened Harttiella (Siluriformes, Loricariidae)

Limnology and Oceanography: Methods, Volume 22, Issue 9, Page 660-669, September 2024.
Abstract To face the current downward trajectory of freshwater biodiversity loss, the implementation of effective biodiversity monitoring programs is of utmost importance. Environmental DNA offers unprecedented opportunities for this aim but several challenges still need to be addressed before implementing efficient species monitoring using eDNA.
