Ibero‐Balearic plant disjunctions: genomic support for rapid and recurrent long‐distance colonizations of the endangered Diplotaxis ibicensis (Brassicaceae) despite no dispersal syndromes

open access: yesPlant Biology, Volume 28, Issue 5, Page 1560-1572, August 2026.
Genotyping‐by‐sequencing data reveal six well‐defined clades in the endangered Diplotaxis ibicensis, endemic to the western Mediterranean Basin and indicate rapid and recurrent long‐distance colonisations across the Balearic Islands and the eastern Iberian coast despite the absence of dispersal syndromes.

Future Global Warming Constrained by Observed AMOC Strength

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The spread in projected global warming across the Coupled Model Intercomparison Project (CMIP) models under idealized forcing has been statistically linked to the inter‐model difference in climatological Atlantic Meridional Overturning Circulation (cAMOC), yet the underlying physical mechanisms remain unclear. Here, we analyze realistic future

Material characteristic of Vetvisty creek placer gold and prospects for atypical-source deposits in the middle course of the Selennyakh river (Momsky and Abyisky district, Yakutia)

open access: yesИзвестия высших учебных заведений: Геология и разведка
Background. The lower-middle course of the Selennyakh River in the Momsky and Abyisky districts of the Republic of Sakha, Yakutia, is characterized by a wide distribution of alluvial gold placers. The absence of obvious potential primary sources of these

Tracing the Persistence and Role of Deep‐Sea Iron Sources in the Pacific Ocean Over the Last 23 Million Years

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Iron (Fe) plays a critical role in marine productivity and the global carbon cycle. The relative contribution of different Fe sources such as atmospheric aerosols, sediment dissolution, and submarine hydrothermalism influences the distribution and biogeochemical cycling of Fe in the ocean. However, distinguishing these Fe sources over time has

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Reassessing Last Glacial Maximum Cooling With Proxy‐Constrained Emergent Relationships

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Reconstructing global temperatures from sparse proxy data remains a key uncertainty in paleoclimate science. Here, we apply an emergent constraint framework that combines statistical relationships from paleoclimate model simulations with proxy‐based estimates to infer unknown climate variables. We compiled a new multiproxy data set of tropical

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...

A Vast Valley Network Beneath the Greenland Ice Sheet

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...
