Teleseismic Radial Anisotropy Reveals a Sill‐Dominated Magma Reservoir Beneath the Valles Caldera, New Mexico

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Valles Caldera (VC), one of the largest Quaternary silicic calderas in North America, formed by explosive rhyolitic eruptions. Seismic studies suggest a crustal magmatic reservoir beneath the caldera with low‐velocity anomalies, but resolving the detailed geometry of localized melt requires constraints from seismic anisotropy.

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Two‐Stage Dolomite Formation in Carbonate Platforms Revealed by Carbonate Clumped Isotope Thermometry

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The “dolomite problem” refers to the scarcity of dolomite in Cenozoic marine environments compared with its abundance in earlier strata. This discrepancy has been attributed to changes in marine environments or to insufficient thermal maturity required for dolomite formation.

Phylogeographic and Potential Distribution of Wild Apricot (Prunus armeniaca) in Xinjiang: Insights From Chloroplast/Nuclear DNA and Ecological Niche Modeling

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study employed integrated analyses of chloroplast DNA and nuclear genes, which revealed significant divergence in genetic structure between the two genomic compartments in Xinjiang wild apricots, reflecting complex evolutionary processes influenced by natural selection, genetic drift, and gene flow. Population history analyses indicated an absence

The Southernmost Known Population of the Monito Del Monte, Dromiciops gliroides

Ecology and Evolution, Volume 16, Issue 3, March 2026.
A range extension for a relict south American marsupial. ABSTRACT The monito del monte (genus Dromiciops) is a small arboreal marsupial endemic to the temperate rainforests of southern South America, and the sole extant representative of the order Microbiotheria. This lineage, considered a sister group of Australian marsupials, is of great evolutionary,

Genomic Insights and Matrilineal Evolution Reveal Potential Dispersal Patterns of Chitala Species (Osteoglossomorpha: Notopteridae) in the Sundaland Biodiversity Hotspot

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study reports the first complete mitochondrial genome of Chitala borneensis and the re‐sequencing of Chitala lopis from Sundaland. Analyses of genetic structure, matrilineal phylogenies, and TimeTree‐based divergence estimates elucidate the evolutionary history and dispersal dynamics of extant Chitala species.
