Physiological Responses to Acute Silver Exposure in the Freshwater Crayfish (\u3cem\u3eCambarus diogenes diogenes\u3c/em\u3e)—A Model Invertebrate? [PDF]

open access: yes, 2002
Adult crayfish (Cambarus diogenes diogenes) exposed to 8.41 ± 0.17 μg silver/L (19.4% as Ag+) in moderately hard freshwater under flow-through conditions for 96 h exhibited ionoregulatory disturbance, elevated metabolic ammonia (Tamm) production and ...

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.

Lake Hańcza – a new site for signal crayfish (Pacifastacus leniusculus Dana) occurrence in Poland

open access: yesArchives of Polish Fisheries, 2018
Crayfish catches were conducted using traps in Lake Hańcza, which is the deepest lake in Poland. Two crayfish populations were found to co-exist in the lake: spiny-cheek crayfish (Orconectes limosus Raf.) and signal crayfish (Pacifastacus leniusculus ...

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.

Fast Colonization of Wild Brown Trout in Nature‐Like Compensation Channel

open access: yesRiver Research and Applications, Volume 41, Issue 3, Page 581-592, March 2025.
ABSTRACT Salmonids and other aquatic migrating species are strongly affected by river damming, but the declining salmonid populations have been traditionally compensated by fish stocking. Nature‐like compensation channels are a new way to mitigate diversity loss in lotic environment.
