Co2 Adsorption Of Anthracite With Different Moisture Contents And Its Implications For Geological Storage, Zhang Jinchao, Sang Shuxun, Han Sijie, Zhang Fengbi, Xu Ang, Liu Qishan

Coal Geology & Exploration

CO₂ geological storage in deep coal seams is regarded as an important pathway to achieve “2030 carbon peak and 2060 carbon neutrality goals”. The moisture content in coal seams plays a significant role in the CO₂ storage capacity mainly based on CO₂ adsorption. In this study, the anthracite from the Qinshui Basin was collected to conduct high-pressure CO₂ adsorption isothermal experiments under dry, moisture-equilibrated and moisture-saturated conditions at 45℃. The CO₂ excess adsorption curve was corrected by the reduction of CO₂ dissolution. The adsorption capacity and adsorption heat were calculated using the modified D-R …

Lithofacies And Sedimentary Environment Evolution Of The Shan2 3 Sub-Member Transitional Shale Of The Shanxi Formation In The Daning-Jixian Area, Eastern Ordos Basin, Sun Yue, Jiang Yuqiang, Xiong Xianyue, Li Xingtao, Li Shuxin, Qiu Zhen, Sun Xiongwei

Coal Geology & Exploration

The Shan₂ ³ Sub-member transitional facies shale of the Permian Shanxi Formation in the eastern margin of the Ordos Basin is a crucial target for future unconventional oil and gas exploration. Based on field outcrop observation, core description and thin-section identification, combined with X-ray diffraction, trace elements test and other analyses, four types of shale lithofacies were identified, including siliceous, siliceous-argillaceous, calcareous-siliceous (or siliceous-calcareous) and argillaceous lithofacies. The petrological characteristics and geochemical indicators show that the depositional environment of the Shan₂ ³ Sub-member inherited the epicontinental sea pattern with relatively gentle topography of the late Taiyuan Epoch. The …

United States Geological Survey: Staff Publications

Chronic exposure of coral reefs to elevated nutrient conditions can modify the performance of the coral holobiont and shift the competitive interactions of reef organisms. Many studies have nowquantified the links between nutrients and coral performance, but fewhave translated these studies to directly address coastal water quality standards. To address this management need, we conducted a systematic review of peer-reviewed studies, public reports, and gray literature that examined the impacts of dissolved inorganic nitrogen (DIN: nitrate, nitrite, and ammonium) and dissolved inorganic phosphorus (DIP: phosphate) on scleractinian corals. The systematic review resulted in 47 studies with comparable data on coral …

School of Natural Resources: Faculty Publications

Grassland ecosystems are under threat globally, primarily due to land-use and land-cover changes that have adversely affected their biodiversity. Given the negative ecological impacts of biodiversity loss in grasslands, there is an urgent need for developing an operational biodiversity monitoring system that functions in these ecosystems. In this paper, we assessed the capability of airborne and spaceborne imaging spectroscopy (also known as hyperspectral imaging) to capture plant α-diversity in a large naturally-assembled grassland while considering the impact of common management practices, specifically prescribed fire. We collected a robust insitu plant diversity data set, including species composition and percent cover from …

Northern Bobwhite Response To Control Of Red Imported Fire Ants In The Gulf Coast Prairie Of Texas, Kelly M. Redmond, Eric D. Grahmann, Fidel Hernández, Leonard A. Brennan, Michael E. Morrow, Timothy Anderson

National Quail Symposium Proceedings

The population decline of northern bobwhite (Colinus virginianus; hereafter, bobwhite) on the Texas Gulf Coast Prairie, USA is largely attributed to habitat loss. However, red imported fire ants (Solenopsis invicta) occur throughout the region and are considered a possible contributing factor to the bobwhite decline. The objectives of our study were to determine the influence of red imported fire ants on bobwhites by comparing bobwhite nest success, survival, and density between sites treated with fire ant bait (treatment) and reference (control) sites. Our study was conducted on 3 private ranches in Goliad and Refugio counties, Texas. …

Northern Bobwhite Response To Vegetation Management And Recovery In South Texas, Rachel A. Smith, Leonard A. Brennan, Humberto L. Perotto-Baldivieso, Fidel Hernández

National Quail Symposium Proceedings

The northern bobwhite (Colinus virginianus; hereafter, bobwhite) requires habitat structure and composition with grass cover for nesting, predator avoidance, and thermal refuge and forb cover for feeding on phytophagous arthropods and seeds. During the past 2 decades, many land managers with interest in promoting quail hunting opportunities have reduced or completely eliminated livestock across South Texas, USA, rangelands. Resting the land from grazing allows vegetation—especially grasses and forbs—to recover and thus provide nesting and foraging habitat for bobwhite and other birds. How bobwhite respond to postgrazing vegetation recovery is of keen interest to rangeland quail managers, but this …

Spatial And Temporal Analyses Of Bobwhite Hunting Dynamics, D.Abraham Woodard, Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso, Neal Wilkins

National Quail Symposium Proceedings

A variety of factors influence the harvest of northern bobwhites (Colinus virginianus) and where that harvest occurs on a landscape. Many of these factors can be quantified and manipulated to distribute harvest pressure across time and space to meet desired spring densities. We collected spatial hunting metrics using global positioning system units on trucks and hunting dogs, along with detailed hunting logs from 211 quail hunts during the 2018–2019, 2019–2020, and 2020–2021 statewide hunting seasons in Jim Hogg County, Texas, USA. We found that hunting parties effectively covered 23.8 ± 0.3 hectares per hour, with hunts lasting 3.5 …

The Efficacy Of Video Cameras To Account For Northern Bobwhites Flushed, But Undetected During Aerial Surveys, Andrea Montalvo, Leonard A. Brennan, Michael L. Morrison, Eric D. Grahmann, Andrew N. Tri

National Quail Symposium Proceedings

Over the past 20 years, conventional distance sampling from a helicopter platform has been used to estimate northern bobwhite (Colinus virginianus; hereafter, bobwhite) density over large areas of rangeland vegetation. However, it has been speculated that aerial surveys can complicate the ability to meet the distance sampling assumption of detecting 100% of the target objects on the transect line due to the restricted observer view from the helicopter. We attempted to use video cameras to determine whether missed detections occurred and whether digital methods could improve the precision of bobwhite density estimates. Our objectives were to 1) determine …

Relationships Between Meteorological And Other Variables And Bobwhite Spring Call Counts, Jeffrey G. Whitt, Kelly S. Reyna

National Quail Symposium Proceedings

Accurate assessment of quail population trends is critical to the success of future conservation efforts. Financial considerations and time constraints often limit population trend estimates to indices, the most common of which are spring call counts and autumn covey counts. While all indices have limitations and caveats, spring call count data specifically possess variability that makes them ill-suited for detecting fine-scale trends. However, because spring call counts record calling males and are relatively easy to conduct, they are assumed to represent an index of breeding potential and produce the most data per unit cost. Here, we examine their variability, comparing …

Applying Multistate Mark-Recapture Models With State Uncertainty To Estimate Survival And Reproduction Of Quail, Rebekah E. Ruzicka

National Quail Symposium Proceedings

Obtaining unbiased estimates of vital rates and understanding how vital rates change in response to environmental stimuli are a continual pursuit of ecologists. Multistate mark-recapture (MSMR) models provide a flexible framework for evaluating dependent vital rates in a comprehensive analysis. For example, a bird must remain alive during breeding season to initiate a nest (i.e., transition from a nonbreeding to a breeding state); thus, the probability that a bird initiates a nest is dependent on the probability that it is still alive. Traditional MSMR models allow only for the estimation of survival, detection, and state transition parameters and depend on …

Highly Variable Autumn Calling Rates Of Northern Bobwhite Following Translocation, John Palarski, Shelby Simons, Bradley W. Kubečka, Theron M. Terhune Ii, Greg Hagan

National Quail Symposium Proceedings

Fall covey counts are a popular index for monitoring population trends of northern bobwhite (Colinus virginianus; hereafter, bobwhite), but their utility is tenuous under different scenarios. Detecting an individual covey is the product of the probability that the covey’s activity center is located within the sampling frame, the probability the covey is located within the sampling frame during the sampling periods, the probability of the covey vocalizing, and the probability an observer will detect a calling covey. Researchers attempt to maximize detection or account for these potential sources of error using standardized protocol of limiting counts to certain …

Impacts To Quail Space Use And Demographics From Oil And Gas Development, Kelsey R. Davis, Eric D. Grahmann, Fidel Hernández, Chase R. Currie, Timothy E. Fulbright, David B. Wester, Humberto L. Perotto-Baldivieso

National Quail Symposium Proceedings

Southern Texas contains some of the last relatively unfragmented habitat for northern bobwhite (Colinus virginianus; hereafter, bobwhite) and scaled quail (Callipepla squamata) in the United States. Development of the Eagle Ford Shale hydrocarbon formation in this region could negatively impact quail and their habitat. Our objective was to examine the indirect effects of oil and gas activity (traffic and noise) on bobwhite and scaled quail on 2 private ranches in southern Texas. In 2015 and 2016, we radio-marked bobwhite and scaled quail in 2 areas where oil and gas activity was occurring (disturbed treatment) and 2 …

Discovering Hidden Geothermal Signatures Using Non-Negative Matrix Factorization With Customized K-Means Clustering, V.V. Vesselinov, B. Ahmmed, M.K. Mudunuru, J.D. Pepin, E.R. Burns, D.L. Siler, S. Karra, R.S. Middleton

United States Geological Survey: Staff Publications

Discovery of hidden geothermal resources is challenging. It requires the mining of large datasets with diverse data attributes representing subsurface hydrogeological and geothermal conditions. The commonly used play fairway analysis approach typically incorporates subject-matter expertise to analyze regional data to estimate geothermal characteristics and favorability. We demonstrate an alternative approach based on machine learning (ML) to process a geothermal dataset from southwest New Mexico (SWNM). The study region includes low- and medium-temperature hydrothermal systems. Several of these systems are not well characterized because of insufficient existing data and limited past explorative work. This study discovers hidden patterns and relations in …

The Effects Of Estradiol-17Β On The Sex Reversal, Survival, And Growth Of Green Sunfish Lepomis Cyanellus, Chad N. Teal, Daniel J. Schill, Susan B. Fogelson, Colby M. Roberts, Kevin Fitzsimmons, Javan M. Bauder, William T. Stewart, Scott A. Bonar

United States Geological Survey: Staff Publications

The feminization of green sunfish Lepomis cyanellus could expand their utility as a game fish or aquacultured species by preventing overcrowding and precocious reproduction in stocked systems. Feminization of green sunfish could also help elucidate information on their sex determination system. We report the feminization of green sunfish cohorts via oral administration of estradiol-17β (E2) during early development. A low-dose (100 E2 mg per kg of diet) and a high-dose (150 E2 mg per kg of diet) experimental E2 treatment were fed to juvenile green sunfish from 30 to 90 days post-hatch. Fish were subsequently evaluated for any treatment effect …

Siphons For Managing Groundwater Discharge And Salinisation In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Siphons are a way of passively moving water from areas of higher hydraulic head to areas of lower hydraulic head, through a pipe. Siphons can be used to lower the watertable under a seepage site if the flow from the siphon (or multiple siphons) is greater than the flow of groundwater to the site. Siphons can reduce surface salt levels at the seepage, but the discharge needs to be to a safe disposal site.

The Department of Primary Industries and Regional Development recommends that siphons are used as part of an integrated water and salinity management program.

Sediment Source Fingerprinting As An Aid To Large-Scale Landscape Conservation And Restoration: A Review For The Mississippi River Basin, Zhen Xu, Patrick Belmont, Janice Brahney, Allen C. Gellis

United States Geological Survey: Staff Publications

Reliable quantitative information on sediment sources to rivers is critical to mitigate contamination and target conservation and restoration actions. However, for large-scale river basins, determination of the relative importance of sediment sources is complicated by spatiotemporal variability in erosional processes and sediment sources, heterogeneity in sediment transport and deposition, and a paucity of sediment monitoring data. Sediment source fingerprinting is an increasingly adopted field-based technique that identifies the nature and relative source contribution of sediment transported in waterways. Notably, sediment source fingerprinting provides information that is independent of other field, modeling, or remotely sensed techniques. However, the diversity in sampling, …

Warming Of The Willamette River, 1850–Present: The Effects Of Climate Change And Direct Human Interventions, Stefan Talke, David Jay, Heida Diefenderfer

Civil and Environmental Engineering Faculty Publications and Presentations

Using archival research methods, we found and combined data from multiple sources to produce a unique, 140 year record of daily water temperature (Tw) in the lower Willamette River, Oregon (1881–1890, 1941–present). Additional daily weather and river flow records from the 1850s onwards are used to develop and validate a statistical regression model of Tw for 1850–2020. The model simulates the time-lagged response of Tw to air temperature and river flow, and is calibrated for three distinct time periods: the late 19th, mid 20th, and early 21st centuries. Results show that Tw has trended upwards at ~1.1 °C …
