The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

New Phytologist, Volume 251, Issue 6, Page 3640-3655, September 2026.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Riverine Export of Millennial and Decadal Carbon From the Amazon Basin

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The riverine mobilization and export of OC from different compartments of the terrestrial biosphere such as standing biomass, organic‐rich surface soils and deep mineral soils have contrasting impacts on the carbon cycle. Heretofore, the distribution of these OC sources in river sediments remains poorly constrained, hampering attempts to close

The Western Amazon, key to the Amazon Basin

Infographic From human to ecological dimensions, the Western Amazon represents a central region for the Amazon Basin. It is home to 27.7 million people, hosts 74% of Amazonian fish species, and plays a fundamental role in aquatic connectivity and the flow of Andean sediments to the Amazon and the Atlantic.

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ56Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Guiana, reveal the response of Fe hosted in laterite to past changes in ...

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.

A Pure Data‐Driven Fully Distributed Model for Spatially Consistent Streamflow Prediction

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Streamflow prediction is essential for water resources management and flood mitigation but remains challenging in large basins due to spatial heterogeneity. Machine learning (ML) models have been widely applied to streamflow prediction, typically relying on explicit routing modules, whereas the potential of pure ML models remains underexplored.

SWOT, Empiricism, and River Modeling

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Given the insurmountable challenge of measuring all rivers in situ, global river models serve as the foundation of freshwater knowledge past, present, and future. We adopt an inductive empirical framework based on Surface Water and Ocean Topography (SWOT) satellite measurements to assess these models.

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...
