Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

Is Strudiella a Devonian insect?

, 2013
The origin of winged insects (Pterygota), one of the planet’s most diverse lineages of organisms, is assumed to lie in the Devonian, but as an extremely sparse fossil record impedes our understanding of their early diversification, any well-preserved ...

Sedimentation model of the middle Devonian clastic succession of the South Tatar Arch, Pashyian Regional stage, Volga-Ural Oil and Gas Province, Russia

Georesursy
The Pashyian Regional stage (horizon) is the main productive unit of the middle Devonian clastic succession of the South Tatar arch. This article presents, for the first time, maps of the lower and upper parts of the Pashyian, including data on sand ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Mutation Pressure and Gene‐Specific Selection Shape Codon Usage Bias in the Chloroplast Genomes of Isoetes, an Ancient Aquatic Vascular Plant Lineage

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study analyzed the chloroplast genomes of 60 Isoetes species to characterize codon usage bias patterns and understand the evolutionary forces shaping this ancient lineage of aquatic vascular plants. The findings reveal a highly conserved chloroplast genome structure with relatively weak codon usage bias, primarily driven by mutation pressure ...

Reforestation Under Climate Change—A Cross‐Regional Deadwood Retention Experiment to Develop Multifunctional Forests on Disturbed Norway Spruce Areas

Ecology and Evolution, Volume 16, Issue 9, September 2026.
The interdisciplinary “ResEt‐Fi” project investigates ecological and economic responses to different deadwood management practices within post‐disturbance landscapes. This article presents the rationale behind different deadwood treatments, the design of our cross‐regional field trial in Central Europe, and outlines an ecological response framework ...
