Population genomics of heterosporous lycophytes: allopatric speciation and historical persistence through paleoclimatic fluctuations

The Plant Journal, Volume 128, Issue 3, November 2026.
SUMMARY Speciation is the fundamental process driving the origin of earth biodiversity. While speciation mechanisms have been revealed in many plant taxa, the evolutionary dynamics of heterosporous lycophytes remain largely unexplored. Here, we used the Selaginella sanguinolenta group, comprising seven montane species in eastern Asia, as a model system.

Dune Crestline Mapping With Deep Learning Reveals Large‐Scale Dune Patterns in NW China

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Dune crestlines encode sediment transport dynamics and atmospheric forcing, yet their large‐scale quantification has been constrained by labor‐intensive mapping or limited resolution. Here we develop an attention‐augmented U‐Net model to automatically extract crestlines from ∼1 m resolution satellite imagery.

Petagram‐Scale Dissolved Organic Carbon Stocks in Alaskan Permafrost Soils

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The pan‐Arctic permafrost region hosts vast amounts of soil organic carbon, a pool increasingly susceptible to climate‐driven changes. Dissolved organic carbon (DOC) is a key component of this carbon pool. However, its stocks and fluxes remain poorly understood due to limited measurements and challenges of tracking subsurface fluxes across ...

Sandy Turbidity Current Acts as a Rusty Carbon Pump at the Shelf Edge

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Sandy turbidity currents (STCs) efficiently sequester organic carbon (OC) through rapid burial. Yet our understanding of OC preservation within STC deposits remains far less constrained, especially considering STC deposits as an inferred major sink for iron‐bound OC (Fe‐OC), a long‐term stabilized form of OC.

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.
