The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations

open access: yesGeoscience Data Journal, Volume 13, Issue 4, October 2026.
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

Richness of Famennian-Tournaisian (late Devonian-early Carboniferous) bryozoans in shallow areas of Palaeotethys and Palaeoasian oceans

open access: yes, 2021
Based on the analysis of data on bryozoan localities in territory of modern Eurasia, changes of the bryozoan richness were calculated in detail for six time slices in the interval from the early Famennian to the late Tournaisian. Highest extinction tempo

Domesticated bacterial origin genes regulate homeostasis of the insect gut microbiome and empower adaptation

open access: yesiMeta, Volume 5, Issue 5, October 2026.
Horizontal gene transfer introduced bacterial CDC genes into the leafhopper genome, providing genetic material for subsequent evolutionary innovation. Different CDC copies diversified at the sequence, structural, and functional levels. RdCDC3 retained its ancestral pore‐forming activity and was recruited for egg defense, whereas RdCDC9 lost its ...

Palynological evidence concerning the Devonian age of the dingle group, Southwest Ireland

open access: yes, 1980
From the Dingle Group, southwest Ireland, generally considered to be of Downtonian age, a presumed Late Emsian palynological assemblage is described, which supports a considerably younger age of the group, viz. late Early Devonian-Middle Devonian. The

Satellite and Reanalysis Dataset Dependence of ETCCDI Extreme Precipitation Trends in Paraná, Southern Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 12, October 2026.
Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal

Archaeopteris trees at high southern latitudes in the late Devonian [PDF]

open access: yes
During the Devonian Period plants first reached forest stature, impacting chemical weathering of rocks, fluvial systems, atmospheric composition and possibly aquatic eutrophication.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 645-667, October/December 2026.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.
