New open access paper! 🎉 Rare earth elements, not so rare? In a wetland below an abandoned Colorado silver mine, REEs were more concentrated than cadmium and lead. Unlike trace metals, they persisted in impacted wetlands. What does this mean for how we monitor and remediate mine-impacted water? 🧪⚒️🌎

Noad and Bonnaventure’s #newarticle has important implications for understanding permafrost distribution in northcentral Yukon. Surface-based temperature inversions are driving patterns of rapid temperature increase with elevation: doi.org/10.1080/1523....
Recent glacier retreat has created new ecosystems known as proglacial margins. Lardet et al.’s #newarticle uses DNA and chemical analyses to show that soil microbes rapidly colonize these areas and are sensitive to environmental changes: doi.org/10.1080/1523....
Edwards et al.’s #newarticle for our “Beringian Environments” collection provides the first detailed sedimentary ancient DNA data from the iconic Duvanny Yar site in the Sakha Republic, revealing dry and disturbed grass-forb vegetation cover: doi.org/10.1080/1523....
🚨NEW RESEARCH ALERT🚨
42 giant pockmarks, some up to 800m wide, have been discovered on the West Greenland shelf, according to Krawczyk et al.’s #newarticle. The figure below is a hypothetical scenario of how these pockmarks formed: doi.org/10.1080/1523....
For our collection "Mountain Hydrology in a Changing World: Building on the Diverse Contributions of Mark “Snobear” Williams", Rue & McKnight published a #newarticle of field studies quantifying acid rock drainage to a watershed in the Colorado Rockies: doi.org/10.1080/1523...
For our collection “Mountain Hydrology in a Changing World: Building on the Diverse Contributions of Mark “Snobear” Williams”, Sommers et al. wrote a #newarticle exploring the microbial world of the Dinwoody Glacier in the Wind River Range, Wyoming: doi.org/10.1080/1523....
