title: Data associated with “How Big is Big Enough? Surprising Responses of a Semi-arid Grassland to Increasing Deluge Size”

description: Data used in manuscript “How Big is Big Enough? Surprising Responses of a Semi-arid Grassland to Increasing Deluge Size.” This study quantifies the impact of deluge size on various ecosystem processes in the shortgrass steppe of Eastern Colorado.
description: Climate change has intensified the hydrologic cycle globally, increasing the magnitude and frequency of large precipitation events, or deluges. Dryland ecosystems are expected to be particularly responsive to increases in deluge size, as their ecological processes are largely dependent on distinct soil moisture pulses. To better understand how increasing deluge size will affect ecosystem function, we conducted a field experiment in a native semi-arid shortgrass steppe (Colorado, USA). We quantified ecological responses to a range of deluge sizes, from moderate to extreme, with the goal of identifying response patterns and thresholds beyond which ecological processes would not increase further (saturate). Using a replicated regression approach, we imposed single deluges that ranged in size from 20 to 120 mm (82.3rd to &gt; 99.9th percentile of historical event size) on undisturbed grassland plots. We quantified pre- and post-deluge responses in soil moisture, soil respiration, and canopy greenness, as well as leaf water potential, growth, and flowering of the dominant grass species (Bouteloua gracilis). We also measured end of season above- and below-ground net primary production (ANPP, BNPP). As expected, this water-limited ecosystem responded strongly to the applied deluges, but surprisingly, most variables increased linearly with deluge size. We found little evidence for response thresholds within the range of deluge sizes imposed, at least during a dry year. Instead, response patterns reflected the linear increase in the duration of elevated soil moisture (2-22 days) with increasing event size. Flowering of B. gracilis and soil respiration responded particularly strongly to deluge size (14- and 4-fold increases, respectively), as did ANPP and BNPP (~60% increase for both). Overall, our results suggest that this semi-arid grassland will respond positively and linearly to predicted increases in deluge size, and that event sizes will need to exceed historical magnitudes before responses saturate.

title: Escherichia coli individual antimicrobial resistance prevalences

description: Primary contact: Paul S. Morley (Paul.Morley@colostate.edu).
description: Cattle Enrolled in Study: September 2007-January 2010.
description: Escherichia coli was isolated from the feces of beef cattle from four commercial feedlots in Alberta, Canada. Each individual was sampled twice, once upon arrival to the feedlot, and again at ≥33 days on feed (DOF). A total of 2,725 isolates were collected from 923 individuals. Antibiotic susceptibility of these isolates to 19 different antimicrobial drugs was determined by broth microdilution and/or disk diffusion assay. Prevalence of resistance to each drug, by sampling time, was calculated (see Figure 2 in associated publication). Data used for determination of prevalences are reported in this database.

title: (EI)2: exploring inclusive engineering identities through freshman engineering curriculum change

description: This collection of files includes data sets, conference papers and posters, and descriptions of curriculum materials from the Exploring Inclusive Engineering Identities project. The collection was created during the period from September 2014 through September 2017.
description: The engineering workforce needs to better represent the diversity of the society it serves by attracting and retaining students from diverse backgrounds. The process students experience to become engineers requires them to acquire technical knowledge but also to identify with the profession. This project is designing a new curriculum for freshman engineering courses to help shape students' emerging engineering identities and expose students to the important role diversity plays in engineering. The curriculum is created to help students recognize the value that diversity brings to engineering in terms of (a) designing better and innovative solutions, and (b) expanding students' conceptions of who can be an engineer. The project is evaluating the effect of the curriculum on students in two different freshman engineering classes. The research questions include the following: How did the intervention change students' attitudes toward diversity in engineering? How did the intervention change students' ability to recognize themselves and others as an engineer? Both quantitative and qualitative methods are being used in this evaluation. The intellectual merit of the project is its transformational approach to retaining diverse students. In particular, the project seeks to change the culture in the educational and work contexts for engineers rather than simply trying to support students from underrepresented groups in engineering. Furthermore, the project contributes to our understanding of how students form engineering identities. The broader impacts of the project include helping to broaden participation in engineering, preparing students for a global work environment, and improving STEM education.

title: Dataset associated with "Effects of fuel moisture content on emissions from a rocket-elbow cookstove"

description: This dataset includes cookstove emissions data per energy delivered and per mass of fuel burned. Emissions data on a per-energy-delivered basis have units of grams per megajoule delivered. Emissions data on a per-mass-of-fuel-burned basis have units of grams per kilogram of fuel. These data were collected in a laboratory cookstoves testing facility at Colorado State University. The data file includes the following columns: 1. test_id - test ID (used internally to identify test replicates), 2. date - date on which the test replicate was conducted, 3. stove - name of the stove model tested, 4. fuel - name of the fuel, 5. fuel_shape - shape of the fuel, either "Milled" or "Split", 6. mc_level - moisture level of the fuel, either "Low", "Medium", or "High", 7. fuel_mc_dry - the moisture content of the fuel on a dry mass basis, in percent, 8. pollutant - name of the pollutant, 9. value - value of the emissions metric, 10. units - units associated with the emission metric, either "g_MJd" or "g_pol_kg_fuel".
description: Exposure to air pollution from solid-fuel cookstoves is a leading risk factor for premature death; however, the effect of fuel moisture content on air pollutant emissions from solid-fuel cookstoves remains poorly constrained. The objective of this work was to characterize emissions from a rocket-elbow cookstove burning wood at three different moisture levels (5%, 15%, and 25% on a dry mass basis). Emissions of CO2, carbon monoxide (CO), methane, formaldehyde, acetaldehyde, benzene, toluene, ethylbenzene, xylenes, fine particulate matter (PM2.5), elemental carbon (EC), and organic carbon (OC) were measured. Emission factors (EFs; g·MJdelivered-1) for all pollutants, except CO2 and EC, increased with increasing fuel moisture content: CO EFs increased by 84%, benzene EFs increased by 82%, PM2.5 EFs increased by 149%, and formaldehyde EFs increased by 216%. Both modified combustion efficiency and the temperature at the combustion chamber exit decreased with increasing fuel moisture, suggesting that the energy required to vaporize water in the fuel led to lower temperatures in the combustion chamber and lower gas-phase oxidation rates. These results illustrate that changes in fuel equilibrium moisture content could cause EFs for pollutants such as PM2.5 and formaldehyde to vary by a factor of two or more across different geographic regions.

description: This study examines the role of soil moisture in modulating convective cold pool properties in an idealized modeling framework that uses a cloud-resolving model coupled to an interactive land surface model. Four high-resolution simulations of tropical continental convection are conducted in which the initial soil moisture is varied. The hundreds of cold pools forming within each simulation are identified and composited across space and time using an objective cold pool identification algorithm. Based on the results, a theory for the impacts of soil moisture on cold pools is developed. Lower soil moisture results in greater daytime heating of the surface, which produces a deeper, drier subcloud layer. As a result, latent cooling by the evaporation of precipitation is enhanced, and cold pools are stronger and deeper. Increased propagation speed, combined with wider rain shafts, results in wider cold pools. Finally, the rings of enhanced water vapor that surround each cold pool when soil is wet disappear when the soil moisture is reduced, due to the suppression of surface latent heat fluxes. Instead "puddles" of enhanced water vapor permeate the cold pools. The results are nonlinear in that the properties of the cold pools in the driest-soil simulation depart substantially from the cold pool properties in the three simulations initialized with wetter soil. The dividing line between the resulting wet-soil and dry-soil regimes appears to be the permanent wilting point, below which transpiration is subdued. These results emphasize the role of land surface-boundary layer-cloud interactions in modulating cold pool properties.

title: SGS-LTER long term nitrogen concentration in LTNPP monitoring on the Central Plains Experimental Range, Nunn, Colorado, USA 1983-2011, ARS study number 6

description: The Short Grass Steppe site encompasses a large portion of the Colorado Piedmont Section of the western Great Plains. The extent is defined as the boundaries of the Central Plains Experimental Range (CPER). The CPER has a single ownership and landuse (livestock grazing). The PNG is characterized by a mosaic of ownership and land use. Ownership includes federal, state or private and land use consists of livestock grazing or row-crops. There are NGO conservation groups that exert influence over the area, particularly on federal lands.
description: This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Repository (http://hdl.handle.net/10217/100254). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. Aboveground plant nitrogen dynamics monitoring consists of two separate data sets. a) Long-term peak-crop nitrogen concentrations have been sampled since 1983 annually from sites sampled for ANPP estimates across the CPER. Plots are clipped for ANPP in August each year and include moderately grazed sites in sections 24 and 25, ungrazed treatments at ESA and owl creek, coarse textured soils in owl creek, fine textured soils in section 25, as well as three catena topopositions in section 24. These datasets have been designed for monitoring and so it is advised to consider calculating average based at the transect level. B) Seasonal dynamics of life-form (dominant grass, forb, shrub species) nitrogen concentrations were obtained from random grab samples of aboveground plant tissue are taken monthly from May-Aug. and in Oct., Dec., Feb., and April from 1983 – 2007 at sites where ANPP has been collected since 1983 (ESA, ridge, mid-slope and swale in section 24). The objectives are to assess annual/seasonal weather and site productivity/management with quantity and quality of forage and/or litter production. Combined, these two data sets also provide an estimate of nitrogen yield. These data can be linked with secondary producer data sets such as annual cattle weight gains, grasshopper abundance, small mammal monitoring, etc., to assess how forage/plant tissue quantity and quality drive population dynamics.

title: Biochemical responses of US Great Plains grasslands to regional and interannual variability in precipitation (1999-2001)

description: The Short Grass Steppe site encompasses a large portion of the Colorado Piedmont Section of the western Great Plains.

The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. Carbon (C) sequestration potential in grasslands is thought to be high due to the large soil organic carbon pools characteristic of these ecosystems. Inputs of C (aboveground net primary productivity) are highly correlated to precipitation across the Great Plains region; however, changes in C pool size at a specific site are governed by the relative input and output rates across time. Our objective was to quantify the ecosystem C response of three grassland community types (shortgrass steppe, mixed grass and tallgrass prairie) to interannual variation in precipitation. At five sites across a precipitation gradient in the Great Plains, we measured net primary production (NPP), soil respiration (SRESP), and litter decomposition rates for three consecutive years. NPP, SRESP, and litter decomposition increased from shortgrass steppe (175, 454, and 47 g C m-2 yr-1) to tallgrass prairie (408, 1221, and 348 g C m-2 yr-1 for NPP, SRESP, and litter decomposition respectively). Increased growing season precipitation between study years resulted in increased NPP, SRESP, and litter decomposition at almost all sites. However, the regional patterns of the interannual NPP, SRESP, and litter decomposition responses differ from each other. This data suggests NPP and SRESP are more sensitive to interannual changes in precipitation than litter decomposition, and that shortgrass steppe sites are more responsive to interannual variability in precipitation than mixed grass and tallgrass prairie.

title: Data associated with "Analysis of acoustic Doppler current profiler mean velocity measurements in shallow flows"

description: There are a total of 25 tab delimited text files that contain the data presented in the figures of the journal article, 'Analysis of Acoustic Doppler Current Profiler Mean Velocity Measurements In Shallow Flows'. In most cases all of the data is organized into text files named by plot and subplot. All text files for Figure 4 are broken into an individual text file for each data set. All data represents processed/analyzed data that was derived from the collected data by the instruments.
description: Acoustic Doppler current profilers (ADCPs) are commonly used instruments for measurement of natural streamflow and flow in manmade channels. Velocities measured in a profile by the instrument are used to estimate the discharge in a channel. A Teledyne RD Instruments StreamPro ADCP was used to measure the mean velocity simultaneously with a laser Doppler anemometer(LDA) in a laboratory flume. An average of 3.9% under-prediction of the mean velocity measured by the ADCP occurred when compared to the measurements of the LDA. The sampling duration of the measurements was also found to impact the mean point velocities measured by up to 50%.

description: In many parts of the world, humans rely on afternoon rainfall for their water supply. However, it is not fully understood how land surface properties influence afternoon precipitation. In fact, disagreement remains regarding the relative prevalence of “wet-soil advantage” regimes, in which wet soils receive more precipitation than do dry soils, and “dry-soil advantage” regimes, in which the opposite occurs. Recent studies have proposed that the permanent wilting point (PWP) soil moisture threshold influences the location and organization of convective clouds. Motivated by this work, we investigate how changes in soil moisture relative to the PWP affect the timing and amount of surface rainfall, as well as how this response depends on the presence or absence of vegetation. This investigation is carried out by conducting several series of high-resolution, idealized numerical experiments using a fully coupled, interactive soil-vegetation-atmosphere modeling system. From these experiments, a new soil moisture-precipitation relationship emerges: in the presence of vegetation, simulations with moderately dry soils, whose initial liquid water content slightly exceeds the PWP, generate significantly less surface precipitation than do those with the driest or wettest soils. This result suggests that simulated “wet-soil advantage” and “dry-soil advantage” regimes may not necessarily be mutually exclusive, insofar as extremely wet and extremely dry soils can both exhibit an “advantage” over moderately dry soils. This non-monotonic soil moisture-precipitation relationship is found to result from the PWP’s modulation of transpiration of water vapor by plants. In the absence of vegetation, a wet-soil advantage occurs instead in these idealized simulations.
