The shifting importance of abiotic and biotic factors across the life cycles of wild pollinators
Abstract Organisms living in seasonal environments are exposed to different environmental conditions as they transition from one life stage to the next across their life cycle. How different life stages respond to these varying conditions is a fundamental aspect of biology and is critical for unders
Climate data from the Rocky Mountain Biological Laboratory (1975–2022)
The Rocky Mountain Biological Laboratory (RMBL; Colorado, USA) is the site for many research projects spanning decades, taxa, and research fields from ecology to evolutionary biology to hydrology and beyond. Climate is the focus of much of this work and provides important context for the rest. There
The dispersal of microbes among and within flowers by butterflies
Abstract Floral microbes, including bacteria and fungi, alter nectar quality, thus changing pollinator visitation. Conversely, pollinator visitation can change the floral microbial community. Most studies on dispersal of floral microbes have focused on bees, ants or hummingbirds, yet Lepidoptera are
New County Records of Aedes aegypti and Aedes epactius in Colorado
ABSTRACT In August and September 2017, we conducted mosquito surveillance in southeastern Colorado by using ovitraps and larval sampling. The aim was to determine if there were established populations of Aedes aegypti and Ae. albopictus in the region. A single female Ae. aegypti was reared from eggs
Contrasts and Commonalities: Hispanic and Anglo Farming in Conejos County, Colorado
Abstract The San Luis Valley farming systems' project sought to identify improved technologies and better decision‐making capabilities for modest‐sized and limited‐resource farms. Characteristics of limited‐resource farms operated by Hispanic and Anglo families, which may or may not be associated wi

Blood parasites of birds of the high Rockies
As far as I am aware, there are no published reports of the blood parasites of birds of the High Rockies. Since environmental conditions are quite different in such regions, with very short summers, uniformly cold nights (often with heavy frost), and low daytime humidity combined with moderate warmt
Hydrological control of rock carbon fluxes from shale weathering
Shale bedrocks hold Earth’s largest carbon inventory. Although water is recognized for cycling elements through terrestrial environments, understanding how hydrology controls ancient rock carbon (Crock) release is limited. Here we measured depth- and season-dependent subsurface water fluxes and pore
Animal-Driven Nutrient Supply Declines Relative to Ecosystem Nutrient Demand Along a Pond Hydroperiod Gradient
Controls from above and below: Snow, soil, and steepness drive diverging trends of subsurface water and streamflow dynamics
Uncompahgre Fritillary Butterfly Demographics: Response to Britten et al.
Using the same methods as Britten, my associates and I ran Pollard transects during four flight seasons at Redcloud Peak and during three flight seasons (1991-93) at Mt. Uncompahgre and found that the populations are declining precipitously, genetic analyses show low heterozygosity, and no heroic ef
New age constraints on the Late Cretaceous lower Williams Fork Formation, Coal Canyon, Colorado
The precise age of terrestrial sediments in the Late Cretaceous Williams Fork Formation of western Colorado is poorly constrained due to a paucity of radiometric data. Sanidine and zircon dating of a volcanic ash encased in coal (i.e., the Coal Canyon ash) within the Cameo-Wheeler coal zone of the l

Survival of Gunnison sage‐grouse <i>Centrocercus minimus</i> in Colorado, USA
Gunnison sage‐grouse Centrocercus minimus has declined from their historic range and recent monitoring has provided evidence that some populations are continuing to decline. The evaluation of long‐term, population‐specific survival rates is important to assess population stability, and is necessary
Facilitated diffusion in erythrocytes of additional mammals
The kinetics of both swelling and shrinking of erythrocytes of the yellow-bellied marmot, golden-mantled ground squirrel, chipmunk, deer mouse, long-tailed vole, montane vole and western jumping mouse indicate that glycerol, ethylene glycol, urea and thiourea penetrate by means of facilitated diffus
Salt Pickup from Agricultural Lands in the Grand Valley of Colorado
AbstractIntroduction of seepage and deep percolation losses to the saline soils and aquifers, and the eventual return of these flows to the river system with their large salt loads, make the Grand Valley in Colorado one of the more significant salinity sources in the Upper Colorado River Basin. A st

Rural-to-Urban Water Transfers: Measuring Direct Foregone Benefits of Irrigation Water under Uncertain Water Supplies
Irrigation water from a southeastern Colorado county has been sold to distant municipalities. The county's junior water right delivered limited and uncertain water supplies which were used on relatively poor soils. The ability of water markets to allocate water to the highest-valued use was addresse
Geomorphic changes resulting from floods in reconfigured gravel-bed river channels in Colorado, USA
Geomorphic changes in reconfigured reaches of three Colorado rivers in response to floods in 2005 provide a benchmark for "restoration" assessment. Sediment-entrainment potential is expressed as the ratio of the shear stress from the 2 yr, 5 yr, 10 yr, and 2005 floods to the critical shear stress fo
