NOAA/WDS Paleoclimatology - Simic fire data from Sapinero Mesa, Western Slope - IMPD USSOM001
The historical role of fire in sagebrush (Artemisia tridentata) landscapes remains poorly understood, yet is important to inform management and conservation of obligate species such as the threatened Gunnison Sage-grouse (GUSG; Centrocercus minimus). We reconstructed fire histories from tree-ring fi

Demographic consequences of changes in environmental periodicity
The fate of natural populations is mediated by complex interactions among vital rates, which can vary within and among years. While the effects of random, among-year variation in vital rates have been studied extensively, relatively little is known about how periodic, non-random variation in vital r
Assessing the causes and scales of the leaf economics spectrum using venation networks in <i>Populus tremuloides</i>
Summary The leaf economics spectrum (LES) describes global interspecific correlations between leaf traits. Despite recent theoretical advances, the biological scale at which LES correlations emerge and the physiological and climatic causes of these correlations remains partially unknown. Here, we te
Responses of soil and water chemistry to mountain pine beetle induced tree mortality in Grand County, Colorado, USA
Proximity to mountain big sagebrush (Artemisia tridentata var. vaseyana) negatively affects performance of two shallow rooted forbs, low larkspur (Delphinium nuttallianum, syn. D. nelsonii) and aspen fleabane (Erigeron speciousus).
Forest responses to increasing aridity and warmth in the southwestern United States
In recent decades, intense droughts, insect outbreaks, and wildfires have led to decreasing tree growth and increasing mortality in many temperate forests. We compared annual tree-ring width data from 1,097 populations in the coterminous United States to climate data and evaluated site-specific tree
The effect of willow proximity on species richness and abundance of birds nesting in aspen <i>Populus tremuloides</i> woodlands.
Riparian zones are widely recognized as important sources of high species diversity. High levels of food resources and habitat complexity in riparian zones attract large numbers of avian species, particularly in arid regions. However, less is known about the importance of riparian proximity in wet m
Protection at a price? Ant interactions with pollinators on aspen sunflower (<i>Helianthella quinquenervis</i>)
A global test of the pollination syndrome hypothesis
The pollination syndrome hypothesis as usually articulated does not successfully describe the diversity of floral phenotypes or predict the pollinators of most plant species. Caution is suggested when using pollination syndromes for organizing floral diversity, or for inferring agents of floral adap
