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 ...

Edifice of Fluvial Terrace Flights, Stacks and Rows
Geosciences, 2020 The paper presents a review of the architecture and structures of river deposits in valleys. A new terminology for some features is included in this review. It presents principles of the fluvial systems with morphological river terraces and fluments (new

In vitro and in sacco determination of neutral detergent fibre digestibility of treated cereal straw
JSFA reports, EarlyView.Abstract Background Cereal straw is hardly digestible due to its complex bonds of lignin, cellulose and hemicellulose. That is why chemical treatments, such as with sodium hydroxide, may help to loosen the bonds and thus increase ruminal digestibility. Neutral detergent fibre (NDF) digestibility is a good predictor of feed intake.

Land Degradation &Development, EarlyView.ABSTRACT Terraced fields and the Gully Land Reclamation Project (GLRP) are important soil and water conservation measures, widely constructed in China's Loess Plateau and other ecologically fragile areas in the world. However, under large‐scale governance scenarios, the impacts of the “terraced fields‐GLRP” cascade system on water and sediment ...

Integrating Machine Learning and StoDyM for Check Dam Site Selection on the Loess Plateau, China
Land Degradation &Development, EarlyView.ABSTRACT Severe soil erosion in the Loess Plateau has led to significant land degradation, threatening agricultural productivity and ecosystem stability. Check dams, as a critical soil–water conservation measure, have proven effective in mitigating sediment loss and reclaiming farmland.

Land Degradation &Development, EarlyView.ABSTRACT Soil erosion is a major environmental challenge in karst regions of Southwest China, where thin soils and high bedrock exposure accelerate land degradation. This study modified the RUSLE model by incorporating bedrock exposure rate to improve erosion simulation in Guizhou Province from 2000 to 2024.

Land Degradation &Development, EarlyView.ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...
