Black bear density in Glacier National Park, Montana
Wildlife Society Bulletin, 2014 We report the first abundance and density estimates for American black bears (Ursus americanus) in Glacier National Park (NP), Montana, USA. We used data from 2 independent and concurrent noninvasive genetic sampling methods—hair traps and bear rubs ...

Revising the tectonic chronology of East–West Antarctica since the breakup of East Gondwana
Nature CommunicationsEast–West Antarctic separation from ~43–11 Ma is well-documented through marine magnetic anomalies in the western Ross Sea, yet multiple lines of evidence suggest earlier extension, including Victoria Land uplift (~55–50 Ma) and reconstruction gaps ...

A seismic analysis of subglacial lake D2 (Subglacial Lake Cheongsuk) beneath David Glacier, Antarctica [PDF]
The CryosphereSubglacial lakes beneath Antarctic glaciers are pivotal in advancing our understanding of cryosphere dynamics, basal hydrology, and microbial ecosystems. We investigate the internal structure and physical properties of Subglacial Lake D2 (SLD2), which is

Glacier Flow and the Growth of the Glacier Grain [PDF]
Journal of Glaciology, 1947 The crystallographic results of the Jungfraujoch Research Party’s investigations were published in the Proceedings of the Royal Society in August 1939. It has since occurred to me that insufficient attention was drawn to another factor affecting the movement and growth of the glacier grain ...

When Do Single‐Species Occupancy Models Outperform Multispecies Models?
Ecology and EvolutionOccupancy models have become increasingly popular for species monitoring and assessment, in part, because detection/non‐detection data are readily obtained using a variety of methods.

Seismic Imaging of the Arctic Subsea Permafrost Using a Least-Squares Reverse Time Migration Method
Remote SensingHigh-resolution seismic imaging allows for the better interpretation of subsurface geological structures. In this study, we employ least-squares reverse time migration (LSRTM) as a seismic imaging method to delineate the subsurface geological structures ...

Nature CommunicationsClimate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes in soil organic matter. Eventually, soil organic matter is transported to alpine and subarctic lakes with yet unknown consequences for ...

Scientific ReportsAntarctic lakes are extreme, oligotrophic habitats that contain microbial communities distinct from those of temperate freshwater systems. Our central question was whether these lakes host microbial communities distinct from those of non-Antarctic ...
