Dispersal is an important individual decision which may influence individual fitness as well as population viability. The social cohesion hypothesis posits more social individuals remain at home, which is supported by prior work across taxa. However, how the sociality and connectivity of the group a

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

The gut microbiome has a well-documented relationship with host fitness, physiology, and behavior. However, most of what is known comes from captive animals where diets and environments are more homogeneous or controlled. Studies in wild populations that experience dynamic environments and have natu

Groundwater age distributions provide fundamental insights on coupled water and biogeochemical processes in mountain watersheds. Field-based studies have found mixtures of young and old-aged groundwater in mountain catchments underlain by bedrock; yet, the processes that dictate these groundwater ag

A review of published research on unpaved road effects on surface-water and shallow ground-water hydrology was undertaken to assist the Baca National Wildlife Refuge, Colorado, in understanding factors potentially influencing refuge ecology. Few studies were found that addressed hydrological effects

Comparing soil pedons from a trail and a nearby equivalent undisturbed pedon allows for a field comparison of changes in soil morphology due to visitor use. The paired pedons technique applied to trails from the canyon rim to the river at the Black Canyon of the Gunnison National Monument successful

At Camp Albion, Boulder County, Colorado, an unusual assemblage of ore and gangue minerals is found in a sheared and brecciated zone cutting the contact between pre-Cambrian gneiss and a composite Tertiary monzonite stock.Petrographic and chemical-mineralogic studies suggest that the ore was deposit

The overwhelming majority of research on wild bumble bees has focused on the social colony stage. Nest-­founding queens in the early season are difficult to study because incipient nests are challenging to find in the wild and the foundress queen flight period is very short relative to the entire ne

Ferberite, the chief tungsten mineral, occurs in (a), coarse textured, drusy veins; (b), stringers with chalcedony and cryptocrystalline quartz; and (c), breccia fragments. In (a), ferberite coats the walls, and scheelite is in the druses; in (b), ferberite likewise encrusts the walls and quartz cru

Organisms inhabiting seasonal environments must fit their life cycle into a limited time window while also synchronizing periods of resource consumption with timing of resource availability. Introduced non‐native species, which often differ in phenology from natives, can alter and expand the seasona

Abstract. In the western US and similar topographic regions across the world, precipitation in the mountains is crucial to local and downstream freshwater supplies. Atmospheric aerosols can impact clouds and precipitation by acting as cloud condensation nuclei (CCN) and ice-nucleating particles (INP
