The Impact of Climate Change on Soil Erosion Rates in the Chernozem Zone of Ukraine

Land Degradation &Development, EarlyView.
ABSTRACT Soil degradation driven by accelerated water erosion threatens global food security. Quantitative estimates of soil erosion losses allow at‐risk areas to be identified and the success of soil management plans to be monitored. However, estimating soil erosion losses under changing climatic conditions is challenging, particularly at the scales ...

Heterogeneity and Controlling Mechanisms of Soil Organic Carbon Stocks Across Erosion Zones in China Under Future Climate Scenarios

Land Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon (SOC), as a key indicator of global carbon cycling and climate change response, plays a critical role in regional ecological security and agricultural sustainability. This study employs three machine learning models including the LightGBM, XGBoost, and random forest to simulate the spatial distribution of topsoil SOC stocks

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

Limnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...
