High resolution longitudinal molecular and morphological tracking of planktonic threats to salmon aquaculture.

The paper identifies planktonic drivers of gill disease and mortality in salmon aquaculture using molecular and morphological methods over a growing season.

Genome-wide DNA methylation predicts environmentally-driven life history variation in a marine fish

This study shows that DNA methylation patterns differ between two life history strategies in capelin, suggesting epigenetic changes, not genetic differences, drive these variations.

The spatio-temporal axis for phenotypic change: a comparison of source and translocated Arctic charr populations after 25 generations

This study compares morphological and genetic divergence between source and translocated Arctic charr populations after 25 generations, finding significant correlations between genetic and morphological differences.

Space-time dynamics in monitoring neotropical fish communities using eDNA metabarcoding

This study uses eDNA metabarcoding to assess spatio-temporal changes in fish communities along the Jequitinhonha River, revealing impacts of dams and highlighting potential eDNA reservoirs.

And if you gaze long into an abyss, the abyss gazes also into thee: four morphs of Arctic charr adapting to a depth-gradient in Lake Tinnsjoen

The paper identifies four morphs of Arctic charr in Lake Tinnsjoen, showing genetic differentiation and ecological speciation along a depth gradient.

Case studies and mathematical models of ecological speciation. V. Adaptive divergence of whitefish in Fennoscandia.

The paper uses mathematical models to study adaptive divergence of whitefish in Fennoscandian lakes, identifying factors like fitness-dependent dispersal and predator pressure that influence morphological speciation.

Polygenic selection drives the evolution of convergent transcriptomic landscapes across continents within a Nearctic sister-species complex.

The paper investigates convergent transcriptomic landscapes in limnetic and benthic whitefish species pairs across continents, finding shared genomic bases for differential gene expression under polygenic selection.

From metabarcoding to metaphylogeography: separating the wheat from the chaff

This study develops a cleaning protocol for COI metabarcoding data to infer intraspecies genetic variability and phylogeographic patterns across marine communities.

Ecological speciation in European whitefish is driven by a large-gaped predator

The paper identifies a large-gaped predator, northern pike, as the driver of ecological speciation in European whitefish by initiating divergence into benthic giants and pelagic dwarfs.

Boreal marine fauna from the Barents Sea diperse to Arctic Northeast Greenland

The paper shows boreal marine species in Northeast Greenland originated from the Barents Sea, suggesting advection through Fram Strait drives Arctic colonization.

Genetic fingerprinting of salmon louse (Lepeophtheirus salmonis) populations in the North-East Atlantic using a random forest classification approach

This study uses IIb-RAD sequencing and random forest algorithms to identify SNPs for fine-scale discrimination of Lepeophtheirus salmonis populations in the North-East Atlantic.
