Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]
, 1993 Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.

The application of time-series MODIS NDVI profiles for the acquisition of crop information across Afghanistan [PDF]
, 2014 We investigated and developed a prototype crop information system integrating 250 m Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) data with other available remotely sensed imagery, field data, and ...

Snow Height Sensors Reveal Phenological Advance in Alpine Grasslands
Global Change BiologyABSTRACTLong‐term phenological data in alpine regions are often limited to a few locations and thus, little is known about climate‐change‐induced plant phenological shifts above the treeline. Because plant growth initiation in seasonally snow‐covered regions is largely driven by snowmelt timing and local temperature, it is essential to simultaneously ...

Density‐dependent habitat selection in plains bison
The Journal of Wildlife Management, EarlyView.Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Seasonal variation of leaf functional traits in sub‐Arctic plants
Oikos, EarlyView.Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...
