Human activities have transformed a significant proportion of the world's land surface, with profound effects on ecosystem processes. Soil applications of macronutrients such as nitrate, phosphorus, potassium or calcium are routinely used in the management of croplands, grasslands and forests to improve plant health or increase productivity. However, while the effects of continuous fertilizatio...

Over the past several decades we have witnessed record-setting wildfires across nearly every continent (1), with recent months as no exception. Widespread burning across western North America includes some of the largest wildfires on record in Washington State, with 2015 total area burned on track to exceed observations of the past two decades (2). Because wildfires have immediate and long-term...

A timberline stand of Libocedrus bidwillii subalpine low forest at Pegleg Flat, Arthur's Pass, was partly destroyed by fire in the late 19th century. Patches of surviving low forest contain very few Libocedrus seedlings and lack young trees of 5-15 cm d.b.h. Only 14 large seedlings and saplings were located in the postfire sere in the formerly burnt areas. The small numbers of seedlings on both...

Tamias umbrinus Allen, 1890, a medium-sized chipmunk commonly called the Uinta chipmunk, is 1 of about 25 species of extant chipmunks. It is distributed in the western United States from southern Montana south to Arizona and from Colorado west to eastern California. T. umbrinus prefers montane and subalpine coniferous forest at elevations between 1,417 and 3,660 m. The species is listed as ‘‘Le...

Species in a Colorado subalpine ecosystem show subtle interdependences. Red-naped sapsuckers play two distinct keystone roles. They excavate nest cavities in fungus-infected aspens that are required as nest sites by two species of swallows, and they drill sap wells into willows that provide abundant nourishment for themselves, hummingbirds, orange-crowned warblers, chipmunks, and an array of ot...

Different models driven by remotely sensed vegetation indexes (VIs) and incident photosynthetically active radiation (PAR) were developed to estimate gross primary production (GPP) in a subalpine grassland equipped with an eddy covariance flux tower. Hyperspectral reflectance was collected using an automatic system designed for high temporal frequency acquisitions for three consecutive years, i...
