Performance assessment of topographic position index and geomorphon-based landform classification for geomorphic analysis of Indian Western Himalayas

Discover Applied Sciences
Landform diversity in the Indian Western Himalaya (IWH) is the result of aggradational and degradational processes through the workings of tectonic, climatic, and anthropogenic forces.

Testing Semi-Automated Landforms Extraction Using Field-Based Geomorphological Maps

Geosciences
The semi-automated extraction of landforms using GIS analysis is one of the main topics in computer analyses. The use of digital elevation models (DEMs) in GIS applications makes the extraction and classification procedure of landforms easier and faster.

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

Nordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications. [PDF]

Adv Sci (Weinh)
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...
