This paper characterizes the upper Carboniferous Brymbo Fossil Forest in North Wales as a Konzentrat-Lagerstätte, detailing its stratigraphy, geochemical proxies, and exceptional fossil preservation—including two new endemic species—to reconstruct the palaeoecology of an equatorial coal-forming rainforest.
This study utilizes a mean-field analysis of long-term grazing data in Inner Mongolia's desert steppe to demonstrate how increasing stocking rates drive a structural transition in plant communities from a single-core network dominated by *Stipa breviflora* to a simplified, grazing-tolerant network, while identifying specific functional group interactions and a critical stocking threshold (≤1.82 sheep units·hm⁻²·half year⁻¹) that maintains ecosystem multistability.
This study reveals that moss diatom communities in the Western Canadian Arctic are significantly more diverse than those in the East, with 86% of the 178 identified taxa being region-specific, establishing a crucial baseline for using these understudied organisms as bio-indicators of climate change impacts.
This paper proposes extending the IPCC contextual vulnerability framework by integrating a policy capacity lens to diagnose the critical gap between latent and realized adaptive capacity, revealing that institutional failures often stem not from a lack of resources or exclusion, but from missing mechanisms to translate expertise and partnerships into actionable planning priorities.
This study analyzes recent sediment dynamics on the continental slope of the Pará-Maranhão basin, revealing that muddy, silt-dominated sediments with high organic matter content are primarily derived from Andean sources via the Amazon River and ocean currents, modulated by regional climatic factors.
This study reveals that degraded mangrove ecosystems in the Sundarban store significantly more soil organic carbon in deeper sediments compared to surface-dominated saltmarshes, while exhibiting distinct greenhouse gas emission profiles characterized by higher methane fluxes in mangroves versus elevated carbon dioxide and nitrous oxide emissions in saltmarshes.
This study utilizes ambient noise interferometry and volumetric strain modeling to reveal that the 2025 Mw 7.7 Myanmar earthquake induced significant, distance-dependent co-seismic seismic velocity reductions along the Sagaing Fault, primarily driven by transient dynamic shaking and modulated by static strain fields, with only partial post-seismic recovery observed.
This study analyzes the cooling potential of Jabalpur's urban parks from 2015 to 2025 using satellite data, revealing that while parks significantly mitigate urban heat islands and improve public health, their cooling effectiveness is driven more by geographical location than size, with a noted decline in the correlation between park size and cooling intensity over time.
This study presents the first detailed characterization of proximal tephra from the 877 CE Hrafntinnuhraun rhyolitic eruption at Torfajökull, Iceland, revealing a complex, multi-phase eruption history driven by fluctuating conduit dynamics, sintering-generated juvenile obsidians, and persistently high magma decompression rates even during the eruption's waning stages.
This study integrates hydraulic testing, saline tracer experiments, and time-lapse electrical resistivity imaging to characterize preferential flow, leakage, and transport pathways within a heterogeneous, confined carbonate aquifer in northwestern Ohio, revealing significant connectivity and non-Fickian transport behavior.
