This study warns that the projected expansion of seaweed farming for climate change mitigation could unintentionally cause significant global ozone depletion and increased surface radiation by the latter half of this century due to emissions of ozone-depleting halogens.
This study demonstrates that ventilation in single-entrance karst caves is governed by buoyancy-driven bidirectional counterflow during cold periods and is significantly modulated by the thermal inertia of the surrounding rock and sediments, which sustains airflow and alters responses to subsequent cooling events.
The newly discovered Early Miocene small mammal assemblage from Harta 2 in western Anatolia, dominated by rodents and assigned to local zone D (MN3), provides critical data for refining the region's biochronology, extending the stratigraphic range of *Vasseuromys duplex*, and reconstructing subhumid paleoenvironmental conditions.
Despite evidence of large-scale vegetation shifts across the Arctic, a 15-year study of vascular plant communities in Southwest Greenland revealed no significant directional changes in diversity, composition, or functional groups at the local scale, highlighting the critical importance of long-term, fine-grained monitoring to capture ecosystem-specific dynamics.
This study integrates SWAT and RUSLE models within a GIS framework to quantify soil erosion and sediment yield in India's Hasdeo River Catchment, enabling the prioritization of critical sub-watersheds and the development of targeted Best Management Practices to mitigate land degradation in mining-affected agricultural areas.
Based on 20 years of fyke net monitoring in Massachusetts coastal rivers, this study reveals that diadromous rainbow smelt populations are experiencing rapid declines and earlier spawning migrations, likely driven by warming marine waters, which underscores the urgent need for targeted resource management to protect these stressed stocks.
Based on field observations in the Oita River estuary, this study reveals that small microplastics (<1 mm) dominate the total microplastic load, exhibit persistent bottom accumulation with a distinct halocline-trapping mechanism, and undergo net seaward export driven by tidal resuspension and ebb currents.
This study identifies four distinct mangrove habitat groups in Lembar Bay, Indonesia, and determines that salinity levels and the sand fraction of sediment are the primary environmental factors driving these community groupings, highlighting their critical importance for mangrove conservation and rehabilitation efforts.
Using salinity and oxygen-isotope data from Hudson and James Bays, this study reveals that river water, rather than sea-ice melt, is the primary driver of seasonal stratification in Arctic marginal seas, implying that increased river discharge under climate change could further limit deep-water renewal and impact broader Arctic biogeochemical and ecological systems.
This paper challenges the classification of the Maksyutov complex as a classic ultrahigh-pressure terrane by proposing a new tectonic-petrological model where diamond and coesite were emplaced by a mantle plume rather than formed in situ, supported by new geochemical data and the "Subduction Initiation Rule."
