Impact of Urban Environmental Indices on Surface Temperature in Dhaka: A Policy‐Oriented Perspective

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
ABSTRACT Dhaka's rapid urban expansion has intensified surface heating and degraded environmental quality. This study analyzes environmental indices from 2015 to 2025, revealing a strong positive relationship between built‐up growth and land surface temperature, and negative associations with vegetation and water presence.

Water Quality Monitoring Using Landsat 8 OLI in Pleasant Bay, Massachusetts, USA

Remote Sensing
Water quality monitoring is essential to assess and manage anthropogenic eutrophication, especially for coastal estuaries in heavily populated areas. Current monitoring techniques rely on in situ sampling, which can be expensive and limited in spatial ...

Configurational Fragility of Forest Landscapes Under Multiple Anthropic Uses

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study revealed that 72.2% of forest fragments and 96.1% of savannas have high configurational fragility, with a predominance of High III and Intermediate I sublevels and occasional occurrences of low fragility (Low III). Fragility is driven by pastures (57.7%), showing that landscapes with the same forest cover differ in fragility depending on the

PRISMA vs. Landsat 9 in lithological mapping − a K-fold Cross-Validation implementation with Random Forest

Egyptian Journal of Remote Sensing and Space Sciences
The selection of an optimal dataset is crucial for successful remote sensing analysis. The PRISMA hyperspectral sensor (with 240 spectral bands) and Landsat OLI-2 (boasting high dynamic resolution) offer robust data for various remote sensing ...

Using Landsat Satellite Imagery to Investigate Spatial and Temporal Variation in Life History Traits in a Long‐Term Study Population of Superb Fairy‐Wrens Malurus cyaneus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We used 27 years of data from an insectivorous passerine in southeastern Australia, the superb fairy‐wren Malurus cyaneus, to assess how climate variation influences vegetation productivity and, indirectly, reproduction and survival via potential trophic interactions.

Performance Assessment of Landsat-9 Atmospheric Correction Methods in Global Aquatic Systems

Remote Sensing
The latest satellite in the Landsat series, Landsat-9, was successfully launched on 27 September 2021, equipped with the Operational Land Imager-2 (OLI-2) sensor, continuing the legacy of OLI/Landsat-8. To evaluate the uncertainties in water surface reflectance derived from OLI-2, this study conducts a comprehensive performance assessment of six ...

Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

Ecography, Volume 2026, Issue 6, June 2026.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...
