Changing Snow Cover and Stream Discharge in the Western United States - Wind River Range, Wyoming [PDF]

open access: yes, 2011
Earlier onset of springtime weather has been documented in the western United States over at least the last 50 years. Because the majority (>70%) of the water supply in the western U.S.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

open access: yesHigh Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Spectral Profiler Probe for In Situ Snow Grain Size and Composition Stratigraphy [PDF]

open access: yes
An ultimate goal of the climate change, snow science, and hydrology communities is to measure snow water equivalent (SWE) from satellite measurements.

Long-term snow and weather observations at Weissfluhjoch and its relation to other high-altitude observatories in the Alps [PDF]

open access: yes, 2018
Snow and weather observations at Weissfluhjoch were initiated in 1936, when a research team set a snow stake and started digging snow pits on a plateau located at 2,540m asl above Davos, Switzerland.

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

open access: yesJournal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

open access: yesJournal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...
