Species-Specific Biomass Allocation Shapes Seagrass Biomass Carbon in an Indonesian Coastal National Park: Evidence from West Bali National Park

This study in West Bali National Park demonstrates that species identity and biomass allocation, rather than shoot density or location, are the primary determinants of seagrass biomass carbon stocks, with the large *Enhalus acoroides* contributing disproportionately more carbon than the more abundant *Halophila ovalis*.

Bioaccumulation of polychlorinated biphenyls (PCBs) in Pseudotolithus senegalensis from the coastal waters of Apam and Shama, Ghana: implications for human health risk

This study assessed PCB bioaccumulation in the demersal fish *Pseudotolithus senegalensis* from Ghana's Apam and Shama coastal waters, revealing spatial variations in congener profiles and bioaccumulation factors while concluding that current exposure levels pose low carcinogenic and non-carcinogenic health risks to humans.

Spatial Dependence in Municipal Heat Exposure Across the Netherlands: Evidence from Environmental Indicators and Spatial Error Modelling

This study demonstrates that explicitly modeling spatial dependence using a spatial-error framework is crucial for accurately assessing municipal heat exposure in the Netherlands, revealing a robust negative association with canopy cover while highlighting that the positive link to groundwater depth is sensitive to model specification.

Multispecies trade-offs and opportunities for reducing megafauna bycatch in tuna purse seine fisheries

This study analyzes four years of observer data from a western Pacific tuna purse seine fishery to reveal that targeting strategies, vessel identity, and FAD type are key drivers of multispecies megafauna bycatch, highlighting the potential for knowledge transfer among fishers to develop more selective practices that reduce mortality across multiple threatened taxa.

Deciphering ore genesis for auriferous deposits in Hangaliya area, Neoproterozoic Nubian Shield, Egypt: Emphasis on P-T conditions and ore-forming processes

This study characterizes the Hangaliya gold deposit in Egypt's Nubian Shield as an orogenic-type system formed by metamorphic fluids at 250–300°C and 0.7–1 Kbar, which precipitated gold within late-to-post-collisional granitic fractures through a three-stage paragenetic evolution.

Australian anthropogenic litter monitoring data: how useful is it for decision making?

This study evaluates Australian anthropogenic litter monitoring data and finds it largely ineffective for decision-making due to poor accessibility, a lack of standardized metadata, and low FAIR scores, prompting recommendations for national data standards and socio-technical improvements to enable evidence-based policy.

Modeling the Ecological Niche of Bactrocera Carambolae Drew & Hancock (Diptera: Tephritidae) for Climate Change Scenarios

Using the CLIMEX model to project the impact of a 3°C global temperature rise by 2100, this study predicts that while the carambola fruit fly (*Bactrocera carambolae*) will remain suitable in specific tropical regions across the Americas, Africa, Australia, and Asia, its overall global distribution will shrink due to increased cold stress during winter seasons.

A delivery gap in electricity grid expansion

This paper analyzes a novel dataset of over 900 European transmission investments to reveal that administrative delays and a tendency to treat projects as optional rather than committed have caused commissioning timelines to exceed official estimates by an average of 4.1 years while resulting in high cancellation rates, thereby inflating investment pipelines and undermining the reliability of grid expansion plans needed to meet 2040 climate targets.
