Understanding soil moisture variability and estimating high-resolution soil moisture at subfield to field scales is critical for agricultural research and applications. However, systematic investigation of subfield scale soil moisture variability over cropland is still lacking from both measurement and satellite remote sensing. In this study, we aim to investigate (1) the characteristics of within-field soilmoisture distribution over typical cropland in the US Midwest and (2) the capabilities of satellite remote sensing in capturing the spatiotemporal variabilities of soil moisture at subfield scale. Specifically, we conducted soil moisture field experiments in three typical commercial agricultural fields (∼85 acres per field) in …

Combining Multi-View Uav Photogrammetry, Thermal Imaging, And Computer Vision Can Derive Cost-Effective Ecological Indicators For Habitat Assessment, Qiao Hu, Ligang Zhang, Jeff Drahota, Wayne Woldt, Dana Varner, Andy Bishop, Ted Lagrange, Christopher M. U. Neale, Zhenghong Tang

School of Natural Resources: Faculty Publications

Recent developments in Unmanned Aircraft Vehicles (UAVs), thermal imaging, and Automachine learning (AutoML) have shown high potential for precise wildlife surveys but have rarely been studied for habitat assessment. Here, we propose a framework that leverages these advanced techniques to achieve cost-effective habitat quality assessment from the perspective of actual wildlife community usage. The framework exploits vision intelligence hidden in the UAV thermal images and AutoML methods to achieve cost-effective wildlife distribution mapping, and then derives wildlife use indicators to imply habitat quality variance. We conducted UAV-based thermal wildlife surveys at three wetlands in the Rainwater Basin, Nebraska. Experiments were …

Natural Resource Conflict And Socioenvironmental Resistance In Arctic States: Assessing Domestic Risks To Circumpolar Security, Jen Evans

Electronic Theses and Dissertations

How does climate change contribute to domestic natural resource conflict and socioenvironmental resistance in the Arctic? The literature assumes that developed Arctic nations possess sufficient state capacity to overcome risks of domestic conflict and unrest posed by regional development and environmental change. Arctic policy correspondingly focuses on natural resource competition, disputes, and conflict at the international level. The mechanisms and processes of domestic natural resource conflict and socioenvironmental resistance in the Arctic have thus been largely ignored in the literature, even though 27 cases of contention have occurred since the ‘shock’ sea-ice melt of 2007.

In this study, I draw …

Procedures For Rangeland Condition Assessment In The Kimberley 2022, Department Of Primary Industries And Regional Development

Natural resources published reports

This report defines the procedures used in 2022 by DPIRD to complete rangeland condition assessment (RCA) in the Kimberley region which has grass-based pastures. For the rest of the pastoral estate, DPIRD uses the Procedures for RCA in the Pilbara and southern rangelands which have predominantly shrub pastures.

RCA is the process DPIRD uses to make systematic, lease-level assessment of rangeland. Rangeland condition considers both the condition of pastures (as defined in the 'Pasture condition guide for the Kimberley') and soils as determined by erosion, using the erosion assessment method on pastoral lands in Western Australia (WA).

School of Natural Resources: Faculty Publications

Canadian and American waterfowl hunters were surveyed to identify their hunting trip preferences. Respondents were individuals that were now participating or had participated in waterfowl hunting, and most had hunted the majority of the last five years. We identified four latent classes of waterfowl hunters that varied in their preferences for harvest, access effort, length of travel, quantity of waterfowl seen, and the potential for interference/competition. We found a diminishing return associated with the number of waterfowl harvested, and that ‘devoted’ and ‘local’ hunters did not perceive appreciable benefit from harvesting more birds beyond harvesting a single bird. Results highlight …

School of Natural Resources: Faculty Publications

Yellowstone National Park thermal features regularly discharge various heavy metals and metalloids. These metals are taken up by microorganisms that often form mats in thermal springs. These microbial mats also serve as food sources for invertebrate assemblages. To examine how heavy metals move through insect food webs associated with hot springs, two sites were selected for this study. Dragon-Beowulf Hot Springs, acid-sulfate chloride springs, have a pH of 2.9, water temperatures above 70 ^oC, and populations of thermophilic bacterial, archaeal, and algal mats. Rabbit Creek Hot Springs, alkaline springs, have a pH of up to 9, some water temperatures …
