A UV–Comfort Co-occurrence Index reveals erythemal exposure opportunity on the South Atlantic coast

This study introduces a UV–Comfort Co-occurrence Index (IVCC) for Argentina's South Atlantic coast, demonstrating that thermal comfort, rather than UV irradiance alone, governs the timing and spatial distribution of human exposure opportunities, with late morning emerging as the critical window when high UV hazard coincides with thermally comfortable conditions.

Divergent rainfall delivery, runoff response, and retained-material composition across contrasting Andean coffee systems

This study demonstrates that in Andean coffee agroforestry systems, canopy-mediated rainfall interception significantly reduces soil water delivery and alters the composition of retained materials, indicating that lower absolute runoff in shaded systems reflects reduced rainfall input rather than superior surface water regulation.

Soil Pb and Cd accumulation and age-dependent biochemical responses in Crocodylus moreletii: Evidence of chronic contamination in a protected urban lagoon

This study demonstrates that chronic lead and cadmium contamination in the urban Laguna de las Ilusions lagoon is associated with significant, age-dependent alterations in biochemical biomarkers of wild *Crocodylus moreletii*, highlighting the species' utility as a sentinel for monitoring environmental stress in tropical urban wetlands.

Long term assessment of Saharan Dust Events in the Eastern Mediterranean by Optical and Microphysical Aerosol Metrics

This study demonstrates that combining optical and microphysical aerosol metrics, particularly a coarse-to-total volume ratio threshold greater than 0.70, significantly improves the reliable detection of Saharan dust events in the polluted urban environment of Athens, Greece, by effectively distinguishing natural dust from anthropogenic fine-mode aerosols.

Subglacial landscape reveal potential future glacial lakes in the Southern Andes

This study presents the first regional reconstruction of subglacial topography in the Southern Andes, revealing that the region's retreating glaciers will leave behind over 3,900 potential future lakes capable of storing nearly 300 km³ of water, with significant implications for future freshwater resources and outburst flood hazards.

Socioeconomic Impacts of Human–Wildlife Conflict and Conservation Challenges in and Around Ambessa Chaka Protected Area, Bambasi District, Beni Shangul Gumuz Reginal State, Ethiopia

This mixed-methods study in Ethiopia's Ambessa Chaka Protected Area reveals that proximity to forest boundaries significantly intensifies human-wildlife conflict, causing substantial crop and livestock losses primarily from olive baboons and lions, while identifying education as a key driver of positive conservation attitudes and recommending species-specific deterrents, habitat restoration, and alternative livelihoods to mitigate these challenges.

Survey and Analysis of Chlorophyll-a Concentration Using the Normalized Difference Chlorophyll Index and Its Correlation with the Occurrence of the Species Emerita Brasiliensis in Four Beaches in Rio de Janeiro

This study utilizes Sentinel-2 satellite data and the Normalized Difference Chlorophyll Index to analyze the correlation between chlorophyll-a concentrations and the occurrence of the bioindicator species *Emerita brasiliensis* across four Rio de Janeiro beaches, aiming to advance coastal environmental management by understanding the species' behavior under varying trophic levels.
