Habitat Variability and Ethnic Diversity in Northern Tibetan Plateau

Scientific Reports, 2017
There are 56 officially-recognized ethnic groups in China. However, the distinct geographic patterns of various ethnic groups in relation to the physical environment in China have rarely been investigated.

Reconstructing hydro-climatological data using dynamical downscaling of reanalysis products in data-sparse regions – Application to the Limpopo catchment in southern Africa

Journal of Hydrology: Regional Studies, 2017
This study is conducted over the data-poor Limpopo basin centered over southern Africa using reanalysis downscaled to useful resolution. Reanalysis products are of limited value in hydrological applications due to the coarse spatial scales they are ...

Highly protected areas buffer against aridity thresholds in global drylands

Nature Plants
Drylands are highly vulnerable to global-scale aridity thresholds that cause drastic reductions in their productivity. While protected areas may help buffer against the impact of aridification, their effectiveness in mitigating the aridity thresholds across global drylands remains virtually unknown.

‘MultiTraits': an integrated R package for analysis and visualization of multidimensional plant traits

Ecography, EarlyView.
The multidimensional characteristics of plant traits and their trade‐offs are central to ecology. However, there is a lack of systematic and standardized tools for analyzing these intricate relationships. To fill this gap, we developed the ‘MultiTraits' R package, which incorporates four complementary analytical modules: competitors–stress tolerators ...

A globally consistent scaling relationship reveals stabilizing effects of dominant species in plant communities

Ecography, EarlyView.
Despite extensive research, stabilizing mechanisms in ecosystems remain uncertain. Taylor's power law (TPL) is a pervasive ecological pattern that describes how variance scales with mean abundance (σ2 = aμᵇ). While TPL has been widely studied within populations, its role across species within communities and its implications for stability remain ...

Environmental thresholds triggering changes in above and belowground biomass carbon in China

Global Ecology and Conservation
Quantifying the dynamics of above and belowground biomass carbon (AGBC and BGBC) is essential for optimizing carbon sink management. However, the environmental thresholds that govern these dynamics under climate change remain poorly understood in China ...

Characteristics of Lacustrine Diamictite and Analysis of Diagenetic Reservoir Facies in the Neogene Lower Youshashan Formation in the Dafengshan Tectonic Belt in the Qaidam Basin

Energy Science &Engineering, EarlyView.
Based on field outcrop data, core descriptions, comprehensive thin section data (plain, cast, and fluorescent), scanning electron microscopy, whole rock analysis via X‐ray diffraction, physical property tests, element logging, core recording, and oil pilot tests, we propose utilizing a mature and practical three component classification method for ...

A Hybrid Fuzzy–Support Vector Machine Framework for Real‐Time Dust Detection and Thermal Mapping in Photovoltaic Panels

Energy Science &Engineering, EarlyView.
A hybrid Fuzzy–SVM framework for real‐time dust detection and thermal mapping in PV panels. ABSTRACT Dust accumulation significantly degrades the energy output of photovoltaic (PV) panels, particularly in arid and semi‐arid regions. While existing studies have separately explored image‐based dust detection, environmental modeling, and machine learning (

Integrating Remote Sensing and Machine Learning for Enhanced Surface Urban Heat Island Analysis and Its Impact on Building Energy Demand

Energy Science &Engineering, EarlyView.
Satellite (MODIS) mapping links Urban Heat Island (UHI) intensity to city‐scale energy demand—higher daytime cooling demand and altered nighttime heating demand—supporting targeted mitigation and planning. ABSTRACT This study examines the surface urban heat island (SUHI) effect on building energy consumption in Tehran from 1998 to 2024, utilizing MODIS
