Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast

open access: yesTransboundary and Emerging Diseases, Accepted Article., 2022
Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Detecting slow introgression of invasive alleles in an extensively restocked game bird

open access: yesFrontiers in Ecology and Evolution, 2014
Interbreeding of two species in the wild implies introgression of alleles from one species into the other only when admixed individuals survive and successfully backcross with the parental species.

Intraspecific Hybrids Versus Purebred: A Study of Hatchery-Reared Populations of Sterlet Acipenser ruthenus

open access: yesAnimals, 2020
Hatchery-reared sterlet originating from the Danube and Volga river basins that showed population-discriminatory alleles on at least one microsatellite locus were used to produce purebred (within-population) and hybrid crosses to evaluate intraspecific ...

Can we identify wild-born salmon from parentage assignment data? A case study in the Garonne-Dordogne rivers salmon restoration programme in France

open access: yesAquatic Living Resources, 2021
Parentage assignment with genomic markers provides an opportunity to monitor salmon restocking programs. Most of the time, it is used to study the fate of hatchery-born fish in those programs, as well as the genetic impacts of restocking.

Physical and chemical tagging methods for the sea urchin Paracentrotus lividus (Echinodermata: Echinoidea)

open access: yesScientia Marina, 2022
The sea urchin Paracentrotus lividus (Lamarck, 1816) (Echinodermata: Echinoidea) is an important economic resource in Europe, but intense harvesting has led to the collapse of several natural populations.
