Mount Etna as a Leaking Pipe of Magmas From the Low Velocity Zone

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Mount Etna, one of the most active volcanoes on Earth, exhibits unusual characteristics in terms of its geological setting, effusion rate, and volatile content. Mount Etna is closely related to the subduction of the Ionian plate below Eurasia, but, chemically, Mount Etna lavas are akin to intraplate magmatism.

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

SPrUCE: Utilizing Ultraconserved Elements of DNA for Population‐Level Genetic Diversity Estimation

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Ultraconserved elements (UCEs) provide ideal candidates for targeted sequencing and cost‐effective acquisition of genome‐wide data. While UCEs have been widely used in phylogenetic studies to reconstruct evolutionary relationships, their use in population‐level research has been limited.

A combinatorial approach to angiosperm pollen morphology [PDF]

open access: yes, 2016
Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning.
