Predictive Ecosystem Health Assessment Under Land‐Use and Vegetation Dynamics in a Semi‐Arid Rift Valley Basin, Ethiopia

Land Degradation &Development, Volume 37, Issue 14, Page 10417-10439, 30 August 2026.
ABSTRACT Land degradation driven by rapid land‐use and climate‐driven vegetation dynamics increasingly threatens ecosystem stability in semi‐arid wetland basins, yet predictive ecosystem health assessments remain limited in Sub‐Saharan Africa. This study evaluates historical dynamics and future trajectories of ecosystem health in the Ziway‐Shalla Sub ...

Weak Tropical Tropospheric OH Response to Idealized ENSO

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The hydroxyl radical (OH) is a key oxidant for methane. Previous studies suggest that OH exhibits interannual variability linked to the El Nino–Southern Oscillation (ENSO), but the sign, magnitude, and underlying mechanisms of this response remain uncertain.

Rapid Increases in Heat‐Driven Extreme Moisture Demand in the Southern Amazon

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Extreme vapor pressure deficit (EVPD), representing the 5% hottest and driest surface air conditions, has risen rapidly over the Southern Amazon during the dry season, especially over forested areas. Its frequency has increased by 7 ± $\pm $ 1.5% (or 11 more dry season days) per decade, and its intensity has increased at rates faster than that

Global Modeling of Atmospheric Amines: Sources and Sinks

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Atmospheric amines (methylamine, MMA; dimethylamine, DMA; and trimethylamine, TMA) are critical to new particle formation, air quality, and climate, yet an integrated global cycling framework remains absent. This study develops a global emission inventory that integrates six source categories spanning anthropogenic sources (agriculture ...

Methane Emissions From Wildfires: Trends and Anomalies

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass burning (BB) provides critical information in developing measurement‐informed

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, Volume 37, Issue 13, Page 9067-9083, 15 August 2026.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Dietary Adaptation in Paranthropus robustus Postcanine Teeth

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
Upper premolar enamel thickness in Paranthropus robustus increased significantly over time, especially in the occlusal region. ABSTRACT Objectives Recent studies of Paranthropus robustus crania identified temporal trends in features associated with increased bite force production, coinciding with environmental shifts toward more arid conditions.
