As a major disturbance to forest ecosystems, wildfires pose serious threat the ecological environment. Monitoring post-fire vegetation recovery is critical quantifying effects of wildfire on ecosystems and conducting resource management. Most previous studies have analyzed short-term (less than five years) limited driving factors temperature precipitation. The lack long-term multi-faceted obser...

An analysis of the landscape spatial structure and diversity in mountain ranges Northeast Siberia is essential to assess how tundra boreal landscapes may respond climate change anthropogenic impacts vast mountainous permafrost Arctic regions. In addition, a precise map required for knowledge-based territorial planning management. this article, we aimed explore enhanced methods analyse Orulgan R...

Abstract Ex-situ conservation places such as botanical gardens require sufficient soil quality to support introduced species from various phytogeographical zones. The of the Botanic Garden Indian Republic (BGIR), Noida, Uttar Pradesh, was evaluated quantify nutrients. dependency one nutrient on other nutrients investigated using Pearson correlation and Multilinear regression analysis (MLRA). At...

Soil moisture (SM) products presently available in permafrost regions, especially on the Qinghai–Tibet Plateau (QTP), hardly meet demands of evaluating and modeling climatic, hydrological, ecological processes, due to their significant bias low spatial resolution. This study developed an algorithm generate high-spatial-resolution SM during thawing season using Sentinel-1 (S1) Sentinel-2 (S2) te...

Several forest change detection algorithms are available for tracking and quantifying deforestation based on dense Landsat Sentinel time series satellite data. Only few also capture regrowth after clearing in an accurate continuous way across a diversity of types (including dry seasonal forests) thus suitable to address the need better information secondary succession assessing restoration acti...

Recent land use changes, the absence of soil protection between crop periods, and extreme precipitation events have been highlighted as major influential factors in fluctuations sediment export last decades at catchment scale worldwide. In this regard, erosion fine-particle are two concerns nutrient loss water-quality decrease (e.g., increasing turbidity vector chemicals). However, while rainfa...
