WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers.

Projections of Atmospheric Moisture Transport Over South America in a Changing Climate

open access: yesInternational Journal of Climatology, Volume 46, Issue 2, February 2026.
End‐of‐century (2071–2100) climate projections show significant contrasts in atmospheric moisture over South America, with increased divergence over Northern Chile and Eastern Brazil and stronger convergence over the La Plata and Magdalena basins. Moisture convergence raises risks of extreme rainfall and floods, while divergence intensifies droughts ...

Hepatic CD4 T Cells Predict Hepatocellular Carcinoma Risk on Metabolic Dysfunction‐Associated Steatohepatitis Patients

open access: yesUnited European Gastroenterology Journal, Volume 14, Issue 1, February 2026.
ABSTRACT Background & Aims Metabolic dysfunction‐associated steatohepatitis (MASH) increasingly drives hepatocellular carcinoma (HCC) development. We characterized inflammatory infiltrates in liver biopsies from MASH patients who developed HCC versus controls to identify predictive immune signatures. Method Formalin‐fixed paraffin‐embedded (FFPE) liver

The Asymmetric Hydrodynamic Structure of a Wind‐Dominated River Plume

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract This study investigates the velocity and salinity structure of the large surface‐attached, low‐latitude, and microtidal plume of the Magdalena River (southern Caribbean Sea) during a period of high freshwater discharge and variable wind conditions. The plume was analyzed through observations at multiple transects along, across, and diagonal to

Optimizing Total Suspended Solids Mitigation in a Data‐Limited Watershed: A Network‐Based Advection–Reaction Model Applied to the Canal del Dique, Colombia

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...
