Predawn and midday plant water potential measurements, collected on terminal twigs using a scholander-type pressure chamber (PMS Instruments, Corvallis, OR, USA). Measurements were collected from 1-3 canopy dominant or co-dominant raments in 12 mature trembling aspen ( Populus tremuloides ) near asp

These data were compiled for monitoring riparian zone trends and changes in the Navajo Nation as part of a study to document riparian ecosystem health and its water use in support of potential restoration efforts. The objective of our study was to monitor the short and medium-term effects on the rip

This data release includes Al-26/Be-10 cosmogenic nuclide concentrations and burial isochron ages for three locations in central Colorado, USA, with preferred burial ages ranging from ~2 Ma to 600 ka, that provide constraints on geologic mapping and chronostratigraphic correlations of Pleistocene Co

Abstract This data release includes a list of high-priority hazardous faults and associated spatial data (regional polygons and buffered fault traces) for the Intermountain West (IMW) region of the United States. These are the top five faults or regions of concern per IMW state, based on the 2025 (v

Heleocola piceanus, a new, relatively large metatherian from Upper Cretaceous (‘Edmontonian’) strata of the Williams Fork Formation in northwestern Colorado is described, based on a recently discovered jaw fragment (MWC 9744), in addition to three isolated teeth initially referred by other studies t

Abstract. The high temporal resolution of thermal infrared imagery from the Geostationary Operational Environmental Satellites R-series (GOES-R) presents an opportunity to observe mountain snow and forest temperatures over the full diurnal cycle. However, the off-nadir views of these imagers may imp

Abstract. Estimating snow mass in the mountains remains a major challenge for remote-sensing methods. Airborne lidar can retrieve snow depth, and some promising results have recently been obtained from spaceborne platforms, yet density estimates are required to convert snow depth to snow water equiv

Una polilla minadora de Yucca baccata, Prodoxus phylloryctus (Wagner y Powell), fue documentada por primera vez en el condado Mesa, Colorado. Prodoxus phylloryctus recientemente recibió el nombre común de minador de hojas de Yucca baccata por parte de la Sociedad Entomológica de América. La primera

ABSTRACT The deadly West Salt Creek Landslide of 2014, one of the largest landslides to occur in the United States in historical time, was surprising in its suddenness and length of runout. Its source area, the edge of Grand Mesa in western Colorado, was potentially the source of other similar lands

AbstractThe persistence of threatened wildlife species depends on successful conservation and restoration of habitats, but climate change and other stressors make these tasks increasingly challenging. Applying climate change vulnerability analyses to contemporary wildlife management can be difficult

The main population of ~5000 threatened Gunnison sage-grouse (GUSG; Centrocercus minimus) in Colorado depends on sagebrush plants that are killed by wildfires, with recovery taking decades, so frequent fire is a threat, but did it occur historically? Early land surveys showed that the historical (pr

This work is the product of an archaeological investigation of the former townsite of Dallas, Colorado. Archival research, drone photography, shovel test pits (STPs), and a test excavation unit were employed to learn more about how the people of Dallas lived, and how they interacted with national sy

The Uncompahgre Uplift within the Colorado Plateau contains several salt anticline valleys. The Moab Valley is situated within one of these valleys which formed as the underlying salt member of the Paradox Formation migrated. As the unit migrated, the resulting collapse of the valley left behind sur

These thoughts are purely my own. No one else is responsible for them. So far as I know, no one agrees with them. And no organization endorses them. But dialogue has to start somewhere. And I have learned through thirty years of building dialogue in the interest of conservation that where there is a
