Stage and discharge prediction from documentary time-lapse imagery
Imagery from fixed, ground-based cameras is rich in qualitative and quantitative information that can improve stream discharge monitoring. For instance, time-lapse imagery may be valuable for filling data gaps when sensors fail and/or during lapses in funding for monitoring programs. In this study, we used a large image archive (>40,000 images from...
Analysis of legacy gravity data reveals sediment-filled troughs buried under Flathead Valley, Montana, USA
Shallow, dominantly silt- and clay-filled erosional troughs in Quaternary sediments under the Flathead Valley (northwestern Montana, USA) are very likely to be hydraulic barriers limiting the horizontal flow of groundwater. Accurately mapping them is important because of increasing demand for groundwater.We used a legacy Bouguer gravity map measure...
Changes in bacterial community structure and carbon metabolism in sandy soil under the long-term application of chitin-r...
...
peer reviewed / Continuous expansion of sandy soil deeply threatens crop security and has become one of the main challenges facing modern society. Chitin-rich organic material and attapulgite have been considered efficient materials to improve degraded soil based on their rich nutrient contents and unique structures. However, their potential effect...
Water availability and atmospheric dryness controls on spaceborne sun-induced chlorophyll fluorescence yield
peer reviewed / Climate change is amplifying the duration, frequency, and intensity of droughts, harming global ecosystems. During droughts, plants can close their stomata to save water, at the expense of a reduced carboxylation rate. When in a carboxylation-limited regime, plants benefit from an increase in water availability, as it increases thei...
Chemical Composition and Insecticidal Activity of Thymus algeriensis Boiss and Reut. Essential Oil against Aphis fabae S...
peer reviewed / Background: The aim of the present work was to study the chemical composition and evaluate the insecticidal activity of Thymus algeriensis Boiss and Reut. essential oil (TAEO) against Aphis fabae Scopoli is a polyphafous which desap many cultivated plants, under shelter and in the open field. Methods: The extraction of essential oil...

Impact of polyvinyl alcohol application and wheat straw mulching on soil loss and infiltration rate in semi-arid tropics...
A study was conducted at Punjab Agricultural University, Ludhiana, Punjab, with the aim of monitoring soil loss and infiltration rate in loamy sand soil. The study focused on the effects of applying polyvinyl alcohol (PVA) and mulch under simulated rainfall conditions. The experimental setup involved testing three levels of PVA (0.5%, 0.75%, and 1....
Nebraska Statewide Groundwater-Level Monitoring Report 2023
This report is a synthesis of groundwater-level monitoring programs in Nebraska. It is a continuation of the series of annual reports and maps produced by the Conservation and Survey Division (CSD) of the University of Nebraska in cooperation with the U.S. Geological Survey (USGS) since the 1950s. Groundwater-level monitoring began in Nebraska in 1...
Quantifying earthworm soil ingestion from changes in vertical bulk density profiles
Soil mixing by earthworms can have a large impact on the fate of nutrients and pollutants and on the soil's ability to sequester carbon. Nevertheless, methods to quantify earthworm ingestion and egestion under field conditions are largely lacking. Soils of the Fennoscandian tundra offer a special possibility for such quantifications, as these soils...
