Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Detection of Changes in Surface Water Bodies Urban Area with NDWI and MNDWI Methods [PDF]

International Journal on Advanced Science, Engineering and Information Technology, 2019
Land surface water bodies, an essential part of the Earth’s water cycle such as rivers, lakes, swamp, and reservoirs, influence the global ecosystem and climate global significantly. Makassar, one of the most populated cities in Indonesia, recently experiences massive development that affects the existence of vegetation area and urban aquatic ecosystem.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, Volume 37, Issue 13, Page 9126-9143, 15 August 2026.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

Improving Cross‐Event Generalization for SAR‐Based Coastal Inundation Mapping via Test‐Time Domain Adaptation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Rapid and reliable coastal inundation mapping from Synthetic Aperture Radar (SAR) imagery is vital for disaster response. Although recent deep learning advances have enhanced this task's accuracy and automation, two major challenges remain: (a) geographic and imaging variations across flood events limit the generalizability of supervised ...

From research to conservation: Site selection for habitat restoration of a narrowly distributed and critically endangered butterfly

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
This study focuses on the conservation of a rare butterfly in northwestern Italy threatened by woody encroachment. Using field data, topography, and remote sensing, we modelled habitat suitability and connectivity. A 0.6‐ha site was selected for restoration, illustrating how predictive models can guide targeted conservation actions.

Habitat loss and fragmentation for an old‐forest species is driven by severe wildfire and drought

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
We examined the long‐term trends in habitat for California spotted owls and attributed habitat changes to specific drivers. We found that the 43% decline in habitat from 1985 to 2022 could primarily be attributed to wildfire and drought. Habitat patches also became smaller and more isolated over time.
