When does a parasite become a disease? eDNA unravels complex host-pathogen dynamics across environmental stress gradients in wild salmonid populations

The paper uses eDNA and niche modeling to show that environmental stressors, not just parasite abundance, drive disease emergence in wild salmonids.

Genetic-based inference of densities, effective and census sizes of expanding riverine meta-populations of an invasive large-bodied freshwater fish (Silurus glanis L.).

The paper estimates effective (Ne) and census (Nc) population sizes and densities for invasive riverine meta-populations of Silurus glanis using genetic and demographic data combined with simulation and statistical methods.

Genetic diversity affects ecosystem functions across trophic levels as much as species diversity, but in an opposite direction

The paper examines how genetic and species diversity affect ecosystem functions across trophic levels, finding they have opposite impacts.

Historical dispersal and host-switching formed the evolutionary history of a globally distributed multi-host parasite - the Ligula intestinalis species complex

This study investigates the evolutionary history of the tapeworm Ligula intestinalis by analyzing mtDNA and SNP data, revealing multiple lineages and the role of historical dispersal and host-switching in its diversification.

Barrier mitigation measures trigger the rapid recovery of genetic connectivity in five freshwater fish species

The paper assesses the impact of barrier mitigation measures on genetic connectivity in five freshwater fish species, finding rapid recovery within twelve months of restoration.

Quantifying the individual impact of artificial barriers in freshwaters: A standardized and absolute genetic index of fragmentation

This paper introduces a standardized genetic index (FINDEX) to quantify the individual impact of artificial barriers on river connectivity using genetic differentiation data.

Genetic erosion reduces biomass temporal stability in wild fish populations.

The paper shows that high genetic diversity in wild fish populations correlates with greater biomass stability over time, despite no difference in maximum biomass compared to low genetic diversity populations.

Systematic conservation planning for intraspecific genetic diversity.

The paper uses systematic conservation planning to identify priority areas for intraspecific genetic diversity across multiple freshwater fish species in France.
