Land Degradation &Development, EarlyView.ABSTRACT Lateral carbon transport induced by soil erosion is a key component of the global carbon cycle. Over the past 50 years, ecological restoration projects in the Loess Plateau of China have increased vegetation coverage. However, the effects of land use, precipitation variability, and landscape factors on lateral carbon transport remain unclear ...

ارزیابی تأثیر روشهای هموارسازی بر محاسبۀ فنولوژی در جنگلهای زاگرس با استفاده از دادههای ماهوارۀ مودیس (مطالعۀ موردی: مریوان) [PDF]
مجله جنگل ایرانمقدمه: تغییر اقلیم به تغییرات عوامل آبوهوایی یک منطقه در دورۀ بلندمدت اطلاق میشود و تأثیر مهمی بر فرایندهای اکولوژیکی آن منطقه دارد. بررسی تغییرات فنولوژی گیاهان، اهمیت زیادی در درک رفتار اکوسیستمهای زمین در مواجهه با تغییرات اقلیمی دارد.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis
Land Degradation &Development, EarlyView.ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Remote Sensing, 2023 Although the Landsat 30 m Enhanced Vegetation Index (EVI) products are important input variables in land surface models, recurring Landsat 5/7 EVI time series over cloud-prone, fragmented, and mosaic agricultural landscapes is still a great challenge. In

People and Nature, EarlyView.Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Remote Sensing, 2021 Vegetation indices are widely used to derive land surface phenology (LSP). However, due to inconsistent illumination geometries, reflectance varies with solar zenith angles (SZA), which in turn affects the vegetation indices, and thus the derived LSP. To

Status and future of seed conservation of threatened plants in the post‐2020 era
PLANTS, PEOPLE, PLANET, EarlyView.Ambitious targets have been set to backup seeds of threatened plants by the global strategy for plant conservation (GSPC), but it is unclear in how far these targets have been met and how seed collection should be organized to meet future challenges. Here, we provide an overview of the status of 44 countries in achieving seed conservation targets.

Respirology, EarlyView.We assessed the diagnostic yield of EBUS‐guided transbronchial mediastinal cryobiopsy (EBUS‐TBMC) compared with EBUS‐transbronchial needle aspiration (EBUS‐TBNA) in patients with suspected mediastinal lymphoproliferative disorders (LPDs). EBUS‐TBMC was superior to EBUS‐TBNA and achieved a high diagnostic yield in patients with suspected mediastinal ...
