An alpine plant shows no decrease in genetic diversity associated with rapid post-glacial range expansion. [PDF]
Am J BotAbstract Premise: While range expansion is hypothesized to be a mechanism for species persistence under climate change, many eco‐evolutionary models describe demographic and genetic processes during expansion that may increase genetic drift, decrease genetic variation, and ultimately decrease relative fitness at the leading edge.

Reconciling the apparent absence of a Last Glacial Maximum alpine glacial advance, Yukon Territory, Canada, through cosmogenic beryllium-10 and carbon-14 measurements [PDF]
Geochronology, 2022 We present a new in situ produced cosmogenic beryllium-10 and carbon-14 nuclide chronology from two sets (outer and inner) of alpine glacier moraines from the Grey Hunter massif of southern Yukon Territory, Canada. The chronology of moraines deposited by

Frontiers in Earth Science, 2022 There are still many uncertainties about the climatic forcing that drove the glacier fluctuations of the Patagonian Ice Sheet (PIS, 38–55°S) during the last glacial period.

Tree Invasions of Subarctic Shrublands Interact With Locally Augmented Snow and Functional Soil Depths: A Case Study in Denali National Park. [PDF]
Ecol EvolIn Denali National Park, Alaska, post‐glacial landscapes are undergoing a shift in successional pathways with the expansion of balsam poplar (Populus balsamifera), altering tundra ecosystem development. We found that poplar‐dominated plots had deeper snowpacks, warmer and deeper soils, and taller vegetation than shrublands, suggesting a feedback loop ...

Frontiers in Earth Science, 2021 A singular precipitation event on the summit glacial slopes of Mexico’s highest volcanic peak, Citlatépetl (also known as Pico de Orizaba), associated with the passage of Hurricane Ernesto across the southern Mexico mainland in August 2012, resulted in a

Skjoldryggen terminal moraine on the mid-Norwegian shelf [PDF]
Geological Society, London, Memoirs, 2016 Terminal moraines are relatively large ridges of diamictic glacial debris produced at the outermost margins of past glaciers and ice sheets. Their identification on land is important in mapping the maximum extent of Quaternary ice sheets (e.g. Svendsen et al. 2004; Benn & Evans 2010).

Submarginal drumlin formation and late Holocene history of Fláajökull, southeast Iceland
Annals of Glaciology, 2016 Fláajökull is a non-surging outlet glacier draining the south-eastern part of the Vatnajökull, southeast Iceland. Fláajökull was stationary or advanced slightly between 1966 and 1995 and formed a prominent end moraine.

Modeling a glacial lake outburst flood process chain: the case of Lake Palcacocha and Huaraz, Peru [PDF]
Hydrology and Earth System Sciences, 2016 One of the consequences of recent glacier recession in the Cordillera Blanca, Peru, is the risk of glacial lake outburst floods (GLOFs) from lakes that have formed at the base of retreating glaciers.
