Early life coregonines collected from Lake Superior in 2019-2021 genotyped with GT-seq and the references used for genetic assignment Early life coregonines collected from Lake Superior in 2019-2021 genotyped with GT-seq and the references used for genetic assignment
This data release contains sample information for a project using genotyping-in-thousands by sequencing (GT-seq) to identify to species early life coregonine fishes that were collected by the U.S. Geological Survey from Lake Superior in 2019-2021. Sample data are provided for both the larval and age-1 coregonines that underwent genetic identification and the reference fishes collected...

A genomic tool to tackle cryptic diversity demonstrates the potential for off-target use of GT-seq panels A genomic tool to tackle cryptic diversity demonstrates the potential for off-target use of GT-seq panels
A comprehensive understanding of life history is vital to successful species conservation and management. When different life history stages are accompanied by considerable morphological or cryptic variation, such as the egg and larval phases exhibited by most fishes, genomic tools are essential for identifying species so that early-life ecology questions can be studied. Genotyping-in...

Drowned river mouth lakes are winter foraging habitats for the expanding Lake Michigan cisco Coregonus artedi population Drowned river mouth lakes are winter foraging habitats for the expanding Lake Michigan cisco Coregonus artedi population
Characterizing fish movements is required for understanding habitat use, energy flow, and trophic structure and can inform fisheries management. Drowned river mouth (DRM) lakes are productive inland habitats in the Laurentian Great Lakes basin used by migratory fishes. Despite recognition of their ecological connections to the Great Lakes, the value of DRM lakes as seasonal habitats is...

Larval cisco and lake whitefish exhibit high distributional overlap within nursery areas Larval cisco and lake whitefish exhibit high distributional overlap within nursery areas
Coregonine fishes, including lake whitefish (Coregonus clupeaformis) and cisco (C. artedi), are socioecologically important in the Laurentian Great Lakes and of conservation concern, but the processes driving recruitment variability are unclear. In Lake Ontario, cisco and lake whitefish exhibit similar spawning behaviours and early life histories, but population trajectories are...
