The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, Volume 101, Issue 4, Page 2053-2076, August 2026.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

A reappraisal of the Middle Triassic chirotheriid Chirotherium ibericus Navás, 1906 (Iberian Range NE Spain), with comments on the Triassic tetrapod track biochronology of the Iberian Peninsula [PDF]

open access: yesPeerJ, 2015
Triassic vertebrate tracks are known from the beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in biochronology and biostratigraphy.

A simple index for assessing cumulative human impacts on mountain lakes

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 8, August 2026.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Low–Ti Continental Tholeiite Origin of Magmas With Calc‐Alkaline Signature in Transcurrent Settings: The Mississippian Matachel Volcanic Field (SW Iberian Massif)

open access: yesGeochemistry, Geophysics, Geosystems, 2023
In the Mississippian Matachel small volcanic field of the Ossa‐Morena Zone (southern Iberian Massif) outpoured basic‐intermediate lavas exhibit geochemical characteristics of Low‐Ti continental tholeiites and calc‐alkaline lavas.

A revision of the genus Armeria (Plumbaginaceae) in peninsular Italy and Sicily through an integrative taxonomic approach

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Armeria in peninsular Italy has been affected by taxonomic ambiguity for more than a century due to high morphological variability. We present a comprehensive revision of peninsular Italian and Sicilian Armeria species, using an integrated taxonomic approach that combines molecular phylogeny, plant and seed morphometrics, and ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Post‐Collisional Evolution in the Southern Variscan Belt: Insights From Numerical Modeling of the Valpelline Series (Western Alps)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The post‐collisional evolution of orogenic belts is commonly marked by high‐temperature metamorphism and widespread magmatism, yet the processes linking collision to post‐collisional dynamics remain difficult to reconstruct due to limited exposure of deep‐crustal levels and uncertainties in the determination of pressure‐temperature conditions ...
