Groundwater level elevation and temperature across Meander C at the Lower Montane in the East River Watershed, Colorado.
This groundwater level elevation and temperature data package is aimed at improving the predictive understanding of hydro-biogeochemical processes at the lower montane site in the East River Watershed, Colorado. The dataset is obtained using pressure transducers placed in shallow wells in the floodp
Geophysical borehole logging data of wells ER-GLS1, ER-GUM1, ER-PLM7, and ER-PLM8 at the East River Watershed, Colorado.
The purpose of this data set is to provide a means of characterizing the bedrock variability both within a single borehole location and across the East River Watershed. The East River is part of the Watershed Function Scientific Focus Area (WFSFA) located in the Upper Colorado River Basin, United St

Total Dissolved Nitrogen and Ammonia Data for the East River Watershed, Colorado (2015-2022)
This data package contains mean values for total dissolved nitrogen (TDN) and ammonia concentrations for water samples taken from the East River Watershed in Colorado. The East River is part of the Watershed Function Scientific Focus Area (WFSFA) located in the Upper Colorado River Basin, United Sta
Soil Environmental Conditions in the East River Watershed, CO.
This dataset contains depth-resolved soil environmental variables collected between June 2016 and October 2018 from the Bradley Meadow site in the East River watershed. Datalogger output from 7 Campbell CS655 12 cm Soil Moisture and Temperature Sensors including depth, temperature, volumetric water
Shale drilling field notes, lithologic descriptions, and core photographs of wells PLM5, PLM8, GUM1, and GLS1 at the East River Watershed, Colorado.
The purpose of this dataset is to maintain a record of the shale drilling field notes, lithologic descriptions, and core photographs taken at the PLM5 (Pumphouse Lower Montane Borehole #5), PLM8 (Pumphouse Lower Montane Borehole #8), GUM1 (Gothic Upper Montane Borehole #1), and GLS1 (GLS1 = Gothic L
Modeling the impact of riparian hollows on river corridor nitrogen exports
This package contains all reactive transport simulation outputs used in "Modeling the impact of riparian hollows on river corridor nitrogen exports" (Rogers, D.B., et al., 2021). The simulation outputs reflect hydrological and biogeochemical behavior of a single, generalized riparian hollow located
Thermoregulatory strategies of Northern House Wrens (Troglodytes aedon) during nestling phase in a western Colorad high altitude population
Climate-ecosystem interactions in montane meadows
Induced morphological defenses in the wild: predator effects on a mayfly, <i>Drunella coloradensis</i>
Host effects on herbivory and pollination in a hemiparasitic plant
The indirect effects of hosts on interactions between parasites and other species are not well understood, and it may be difficult to predict the outcome of host species effects on parasite performance due to the complexity of potential direct and indirect effects. For example, parasitic plants obta
The effect of nest box temperature on nestlings growth rate and parental feeding rates in a montane population of house wrens, Troglodytes aedon
The effect of hermaphrodite density and frequency at three spatial scales on the polen receipt and seed set of gynodioecious Geranium richardsonii (Geraniaceae)
Gynodioecy is a mode of sex expression where male sterlie (hereafter female) plants and hermaphroditic plants coexist within a population. In order for the females to be maintained by natural selection, they must have experienced an increased fitness. Fitness is defined as the ability of genotype or
Trophic structure of montane meadows and a testing of the constant food web connectance in space
The effect of Yellow bellied marmot (Marmota flaviventris) on the sub-alpine vegetation of the Colorado rocky mountains
Inter- and intra-specific competition between and among <i>Nicrophorus investigator</i> and <i>Nicrophorus defodiens</i>
Plant resource allocation and herbivory for <i>Helianthella quinquenervis</i> (Asteraceae) over an elevational gradient
Resources obtained from the environment are allocated to many plant parts and functions. Resource allocation into defense, growth, and reproduction was examined for Helianthella quinquenervis, the Aspen sunflower, for three field sites over an elevational gtadient. H. quinquenervis has evolved a mut
Connecting pollination deficits and pollinator declines: can theory guide us?
Response of nitrogen cycling to simulated climate change: differential responses along a subalpine ecotone
SummaryIn situnitrogen (N) transformations and N availability were examined over a four‐year period in two soil microclimates (xeric and mesic) under a climate‐warming treatment in a subalpine meadow/sagebrush scrub ecotone. Experimental plots that spanned the two soil microclimates were exposed to
