Automated vicarious radiometric validation of spaceborne thermal infrared sensors at non-dedicated validation sites using deep learning-based cloud filtering

International Journal of Applied Earth Observations and Geoinformation
Vicarious calibration/validation (Cal/Val) is essential for ensuring the radiometric accuracy of spaceborne thermal infrared (TIR) sensors. Anticipating an increase in the number of TIR sensors in the near future, this study developed an automated ...

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.

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

Precipitation Modulates the Impact of Human Activities on Riverine Food Webs Revealed by Environmental DNA

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The effects of human activities on ecological networks are associated with climate, with increased precipitation weakening their negative impact. ABSTRACT The functionality of global rivers has been adversely affected by environmental pollution and habitat degradation.

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.

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 ...

Low sediment retention efficiency limits delta formation in tectonically confined high‐energy coastal systems

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Conceptual framework showing how tectonic confinement, steep monsoon‐driven river dynamics, high‐energy coastal processes and offshore sediment dispersal together limit sediment retention at the Narmada–Tapi river mouths, suppressing sustained subaerial delta formation despite high sediment supply. Abstract Although deltaic growth is commonly linked to
