Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Hydracarina from Glacier National Park

Transactions of the American Microscopical Society, 1930
Material for this study consisted of collections of water mites made by Dr. R. M. Muttkowski in Lake McDonald, Glacier National Park, Montana, during the months of July and August, 1925. The author wishes here to express her thanks to Dr. Muttkowski for the opportunity to examine this material and thus to add a little to our scanty knowledge of the ...

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique

Journal of Quaternary Science, EarlyView.
ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Landslide Risk Associated with Glacier Tourism in the Mt. Everest Region (Sagarmatha National Park), High-Mountain Nepal

Earth
Assessment of landslide risk is crucial given the substantial related economic losses and infrastructure damage in mountain areas every year. Particularly, the Sagarmatha National Park (SNP), a key destination for Himalayan glacier tourism, remains ...

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Composition and functionalities of peanut protein concentrates using ethanol as a defatted solvent and a precipitating agent

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Defatted solids (DSs) from vegetable oil extraction represent valuable feedstocks for producing protein concentrates with tailored functional properties. In the present study, using peanut protein concentrates obtained from press cakes defatted with ethanol (DSEt) or hexane (DSHx), we aimed to evaluate ethanol as a green solvent for
