Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.Abstract Near‐surface wind regimes govern critical Earth system processes including dust mobilization, ocean mixing, and wildfire spread, yet their multi‐decadal evolution under anthropogenic forcing remains poorly constrained. Here we quantify extreme wind frequency changes (1981–2024) using ERA5‐Land reanalysis with a monthly aggregation approach ...

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

Land Degradation &Development, Volume 37, Issue 13, Page 9008-9020, 15 August 2026.ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

Impact of Nitrogen Deposition on Carbon and Nitrogen Cycling in Peatlands Under Land‐Use Change
Land Degradation &Development, Volume 37, Issue 13, Page 9098-9113, 15 August 2026.ABSTRACT Increasing nitrogen (N) deposition significantly alters carbon and N dynamics in peatlands by affecting microbial processes, enhancing greenhouse gas emissions and nutrient leaching into adjacent waters. However, how peatland conversion for agriculture and forestry influences the fate of added N under elevated atmospheric deposition remains ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Hydrological Processes, Volume 40, Issue 8, August 2026.Land cover and elevation are shown to influence the proportion of stream source waters across glacial and non‐glacial streams. Groundwater makes up a large proportion of both early season and late season flow in most glacial and non‐glacial streams, while the timing of snow and ice melt is driven by the presence or absence of a glacier within the ...

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 593-604, August 2026.Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.

Limnology and Oceanography, Volume 71, Issue 8, August 2026.Abstract The marine microbial food web is a key driver of global carbon cycling, mediating the production, consumption, and remineralization of organic matter in the ocean. Within this food web, viruses exert strong top‐down control by infecting and lysing both phytoplankton and heterotrophic bacteria.
