Conceptualizing dust emission areas and hotspots over the Aeolian landforms via remote-sensing aerosol algorithms (case study: Lake Urmia, a major hypersaline lake in the Middle East)

Geoscience Letters
Currently, endorheic saline lakes are rapidly being desiccated worldwide at an alarming rate. Thus, the role of dried-up saline lakebeds in wind erosion and dust emission in the regional climate system and its adjacent environment is poorly understood ...

An in vitro comparison of PDGF‐BB release from composite graft materials containing leukocyte‐rich platelet‐rich fibrin and platelet‐derived growth factor‐BB and β‐tricalcium phosphate

Journal of Periodontology, EarlyView.
Abstract Background The clinical efficacy of growth factors in regenerative procedures may depend on both dosage and sustained delivery during critical phases of healing. This study aimed to evaluate in vitro release kinetics of platelet‐derived growth factor‐BB (PDGF‐BB) from various graft materials, including recombinant human PDGF‐BB (rhPDGF‐BB ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Land Use Spatial Optimization Based on Multi‐Objective Ant Colony Algorithm and FLUS Model: A Case Study of Korla City and Tiemenguan City, China

Land Degradation &Development, EarlyView.
ABSTRACT In southern Xinjiang, China, scarce land and water resources and fragile ecosystems have intensified land use conflicts, making land resource allocation optimization essential for sustainable development in arid oasis areas. Focusing on Korla and Tiemenguan, this study aims to coordinate economic benefits, ecological benefits, and food ...

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

Limnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...
