Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, Volume 36, Issue 18, 2 March 2026.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

open access: yesThe Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

open access: yesGlobal Change Biology Communications, Volume 1, Issue 1, March 2026.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

open access: yesGeoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

New Zealand Geological Timescale 2025

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Initiation of the Ferrar Large Igneous Province Started in Southern North Victoria Land, Antarctica, With Shallow Emplacement of Sills Causing Magma‐Soft‐Rock Interaction and Phreatomagmatic Eruptions

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Early Jurassic volcanism was in the southern north Victoria Land portion of the Ferrar Large Igneous Province preceded by multiple phases of shallow‐level intrusions of Ferrar sills into the 300 m thick cover of sedimentary rocks of the Triassic‐Jurassic Victoria Group.

Mantle Xenolith Evidence for Lithospheric Thinning and Metasomatic Modification Beneath the Eastern Fiji Plateau: Implications for Samoan Plume Supply, Intraplate Volcanism, and Orocline Formation

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
We provide petrographic and geochemical characterisation of mantle xenoliths from Koro Island, eastern Fiji. Several lherzolite xenoliths display spinel–pyroxene symplectite textures, including preserved former grain boundaries, consistent with garnet breakdown that we attribute to thinning of a preexisting garnet‐facies lithospheric mantle beneath ...

Tourism Resilience in the Face of Crises: The Adaptive Capacity of Travel Demand

open access: yesInternational Journal of Tourism Research, Volume 28, Issue 2, March/April 2026.
ABSTRACT Crises have the potential to significantly disrupt travel and tourism. However, tourism has shown a remarkable ability to recover, highlighting its resilience and adaptive capacity. Tourism resilience refers to the way tourism systems successfully absorb a crisis, using their adaptive capacity to reorganize and bounce forward.
