Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Demographic Models and Behavioral Assessments Uncover Distinct Species Histories in the Pseudocryptic Nudibranch Genus Hermissenda

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We reconstructed the speciation history of the recently split pseudocryptic nudibranch genus Hermissenda, finding divergence times in the Pleistocene (1.29–0.55 mya). Demographic modeling and behavioral experiments show no gene flow and assortative mating between sympatric species H. crassicornis (s.s.) and H.

Seed fossil record of Solanaceae revisited

open access: yesTAXON, Volume 75, Issue 1, Febuary 2026.
Abstract The fossil record for Solanaceae has a complex taxonomic history, with many species originally described in the family being subsequently shown to belong in other plant families. In this work, we present an in‐depth analysis of the nightshade seed fossil record, which corresponds to the largest amount of fossil material for the family.

How Sediment Supply, Sea‐Level, and Glacial Isostatic Oscillations Drive Alluvial River Long‐Profile Evolution and Terrace Formation

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract For over a century, alluvial river terraces have been used as archives of tectonic deformation or changes in water discharge, sediment supply, and sea level. Despite this long history, such efforts remain challenging: using terraces as deformation markers requires knowledge of their initial geometry, and most attempts to attribute terrace ...

Interplay Between Tectonics and Submarine Mass Transport Deposits in Cortes Basin: New High‐Resolution Geophysics in the Outer California Borderland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Outer California Borderland (OCB) is an active transform plate boundary offshore Southern California, where the relationship between faulting and submarine mass transport deposits (MTDs) remains poorly understood. Onshore paleoseismic data provide high‐resolution earthquake records, whereas marine geophysical data capture longer‐term ...

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3
