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 ...

Ringtail (Bassariscus astutus) survival in southwestern Oregon

The Journal of Wildlife Management, EarlyView.
We captured and monitored radio‐collared ringtails over 2 years to estimate monthly and annual survival rates. We found that annual survival rates were much higher within forested landscapes in Oregon than for populations in the southwestern United States.

Simulated Root Exudation Gradient Reveals Dosage‐Dependent Carbon Sequestration in Desertification Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Root exudates serve as a key driver for the restoration of soil organic carbon (SOC), particularly in aeolian desertification ecosystems where aboveground litter retention is limited. While Salix cupularis is widely planted as an effective pioneer shrub for ecological rehabilitation on the Qinghai‐Tibet Plateau, how the quantity of its root ...

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium

Revista Brasileira de Ciência do Solo, 2013
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of

Land Use and Land Cover Analysis for Solid Waste Management in NCT Delhi Using Fusion Aware Segformer

Land Degradation &Development, EarlyView.
ABSTRACT The use of Land Use Land Cover (LULC) analysis is a fundamental requirement for urban solid waste management (SWM); however, conventional LULC analysis methods are not well suited to the spatio‐temporal variability, multi‐sensor heterogeneity, and seasonal variations of highly dynamic urban environments.

Effect of litter quality and Home-Field advantage on leaf-litter decomposition of Tree of heaven and European black pine leaf-litters

مجله جنگل ایران, 2021
Litter quality plays a key role in the decomposition process and nutrients dynamics. In most studies, it is assumed that litter has a higher rate of decomposition in its ecological site. Evidence for this theory has not yet been fully confirmed.

Biological Salt‐Pump Effect: Long‐Term Stand Development of Haloxylon ammodendron and Its Role in Reshaping Soil Hydrothermal and Salinity Regimes

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation in the desert–oasis ecotone induces soil desiccation and secondary salinization. However, the seasonal dynamics of soil water–heat–salt interactions across plantations of different stand ages in arid regions remain unclear. Here, we investigated the seasonal patterns and coupled relationships of soil water–heat–salt dynamics in ...

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

Leaf litter decomposition of dominant species of meadow steppe in Mungunmorit soum, Tuv province

Mongolian Journal of Biological Sciences
The decomposition of plant litter is a fundamental process in the carbon and nutrient cycling of ecosystems and is an important source of organic and inorganic nutrients for plant growth in grassland ecosystems.

Assessing Soil Erosion in a Typical Karst Region: A Model Improved by Bedrock Exposure Rate in Guizhou Province

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.
