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

Xenopus laevis and Emerging Amphibian Pathogens in Chile [PDF]
, 2016 Amphibians face an extinction crisis with no precedence. Two emerging infectious diseases, ranaviral disease caused by viruses within the genus Ranavirus and chytridiomycosis due to Batrachochytrium dendrobatidis (Bd), have been linked with amphibian ...

Environmental DNA, Volume 7, Issue 3, May–June 2025.We present 125 eDNA quantitative real‐time polymerase chain reaction (qPCR) assays against animal species of importance to North America. We show how these assays were designed and validated to comply with the Canadian national eDNA standards to allow confident eDNA detection for coastal and inland ecological surveys and biosurveillance.

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.Abstract Creatures grown on the island are more susceptible to genetic vulnerabilities because of their isolated nature and often limited genetic diversity. Understanding the genetic structure of these populations is crucial for effective conservation strategies, especially for the species that are commonly found in aquaculture and may inhabit islands.

Ecological Monographs, Volume 95, Issue 1, February 2025.Abstract Batrachochytrium dendrobatidis (Bd) is a globally distributed fungal pathogen of amphibians that has contributed to one of the largest disease‐related biodiversity losses in wildlife. Bd is regularly viewed through the lens of a global wildlife epizootic because the spread of highly virulent genetic lineages has resulted in well‐documented ...

A phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824)
Zoologica Scripta, Volume 54, Issue 1, Page 103-118, January 2025.Abstract In spite of their important roles in many ecosystems, data regarding population structure and biogeographic patterns of leeches are scarce. To begin to address this knowledge gap, we herein perform a phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824). A total of 224 M. decora specimens were collected
