Persistence of Environmental DNA in Freshwater Ecosystems [PDF]
, 2011 International audienceThe precise knowledge of species distribution is a key step in conservation biology. However, species detection can be extremely difficult in many environments, specific life stages and in populations at very low density. The aim of

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
