The evolution of an “owl‐like” auditory system in harriers: Anatomical evidence
Journal of Anatomy, EarlyView.Harriers hunt relying on sound, with an accuracy to localize sound sources comparable with owls. To assess whether they have owl‐like auditory specializations, we analyzed brain and skull structures using histology and microCT scans. Harriers possess an enlarged external acoustic meatus and significantly expanded auditory brainstem nuclei, up to 12 ...

Unexpected pathway for intercontinental movement into the Nearctic revealed by phylogenetic analyses
Zoologica Scripta, EarlyView.Abstract Much of North America's freshwater biodiversity is derived from Palearctic lineages. Isopods of the Holarctic family Asellidae are among the most widespread and diverse freshwater crustaceans, but Nearctic species are poorly studied. We examined the evolutionary history of the family, utilizing Sanger sequencing of mitochondrial and nuclear ...

ArcticNet: A Deep Learning Solution to Classify Arctic Wetlands [PDF]
arXiv, 2019 Arctic environments are rapidly changing under the warming climate. Of particular interest are wetlands, a type of ecosystem that constitutes the most effective terrestrial long-term carbon store. As permafrost thaws, the carbon that was locked in these wetland soils for millennia becomes available for aerobic and anaerobic decomposition, which ...
