Dynamical Downscaling of Seasonal Forecasts Using WRF: Assessing Precipitation and Wind Speed Predictability over the Indonesian Maritime Continent

This study evaluates the performance of WRF-dynamically downscaled CFSv2 seasonal forecasts over the Indonesian Maritime Continent, revealing that while the model effectively captures monsoonal patterns and precipitation anomalies with systematic wet biases, wind speed predictability is limited to approximately 14–21 days and increases with lead time, whereas precipitation errors exhibit high day-to-day variability.

Establishing bioerosion rates for a burrowing sea urchin and evaluating its role in coral reef bioerosion

This study quantifies the bioerosion rates of the burrowing sea urchin *Echinostrephus molaris* and its environmental drivers across the Lakshadweep Islands, revealing that while these urchins significantly contribute to reef erosion, their actual impact is approximately 27% lower than previous estimates based on grazing species, necessitating a re-evaluation of local coral reef carbonate budgets.

Air Pollution Exposure During Urban Running: A Randomized Crossover Comparison of Particulate Matter Exposure on Park, Roadside, and Residential Routes with Consideration of Rush-Hour Timing

This randomized crossover study demonstrates that running in urban parks and avoiding morning rush hours significantly reduces particulate matter exposure compared to roadside or residential routes, particularly under calm, humid, and high-pressure weather conditions.

Effects of Polypropylene Microplastics and Aging Time on Nitrogen and Phosphorus Dynamics and Enzyme Activities in Soil

This study demonstrates that the addition of polypropylene microplastics to soil, particularly over extended aging periods, significantly alters nitrogen and phosphorus dynamics and suppresses key enzyme activities, primarily by increasing nitrite nitrogen levels and indirectly affecting soil biochemical processes.

IPCC-Aligned Framework for Flood Vulnerability Indices: A Scoping Review of Geospatial Indicators for Adaptation Planning

This scoping review harmonizes 2,437 geospatial indicators from 131 studies into an IPCC-aligned framework to address methodological inconsistencies in Flood Vulnerability Indices, thereby providing a transparent, FAIR-compliant catalogue to support evidence-based urban flood adaptation planning.

The Microplastic Menace: Polymer-Specific Impacts on Bacterial Communities and Carbon Cycling in Temperate Forest Soils

This study demonstrates that in temperate forest soils, the identity of microplastic polymers, their concentration, and soil type jointly modulate short-term bacterial and fungal community diversity, enzyme activity, and carbon cycling processes.

Body size reduction across Arctic flies: Evidence from two sampling periods separated by 60 years

This study demonstrates that eight Arctic fly species experienced a roughly 5% decline in body size over a 60-year period, a trend likely driven by rising spring temperatures and underscoring the critical need for digitized historical collections and long-term monitoring to track climate-induced trait shifts in Arctic ecosystems.

Integrated multi-hazard climate risk across Egypt's water–coast–delta system: reservoir evaporation, coastal inundation, and socio-economic vulnerability

This study integrates assessments of Lake Nasser evaporation, Red Sea coastal screening, and Mediterranean Delta inundation within the IPCC AR6 framework to demonstrate that distinct climate risk pathways across Egypt's water–coast–delta system necessitate differentiated adaptation strategies.

Forecasting Climate and Weather Variability Using AI-Based Hybrid LSTM and XGBoost Model

This paper proposes and validates a hybrid AI framework integrating LSTM and XGBoost models to accurately forecast key meteorological parameters in Eastern Ethiopia, demonstrating superior performance over standalone models and providing critical insights for enhancing disaster risk management and early warning systems against climate variability.

First records of Anemonia manjano (Carlgren 1900) in the Hawaiian Islands and the aquarium hobby as an increasingly important pathway for marine invasive species.

This paper reports the first discovery of the invasive majano anemone (*Anemonia manjano*) in Hawaiian waters at two O'ahu locations, where its rapid expansion from aquarium-derived introductions underscores the growing role of the aquarium hobby as a vector for marine invasive species.
