Geology of giant quartz veins and their host rocks from the Eastern Pyrenees (Southwest Europe)

open access: yes, 2022
Giant Quartz Veins (GQVs) are ubiquitous in different tectonic settings and, besides being often related to hydrothermal ore deposits, also represent large-scale fingerprints of the structural and geochemical history of the rocks in which they are hosted.

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 615-638, July 2026.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Avaluació regional de la dinàmica recent de l'ecotò bosc subalpí-prats alpins als Pirineus [PDF]

open access: yes, 2008
[cat] El límit altitudinal del bosc, o ecotò superior bosc-prat alpí, constitueix per definició, la frontera entre l'estatge subalpí i l'estatge alpí separant, per tant, sistemes ecològics adjacents.

Landscape Connectivity and Suitable Habitat Analysis for Wolves (Canis lupus L.) in the Eastern Pyrenees

open access: yes, 2020
Over the last few decades, much of the mountain area in European countries has turned into potential habitat for species of medium- and large-sized mammals.

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

Reconstructing a Super-Eruption From the Upper Ordovician Period in the Eastern Pyrenees, Spain [PDF]

open access: yesLithosphere
The Pyrenean basement rocks, NE of the Iberian Peninsula, southwestern Europe, include evidence of several pre-Variscan magmatic episodes which indicate the complex geodynamic history of this segment of the northern Gondwana margin from late ...

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

Observational Uncertainty in Deep Learning Climate Downscaling and Projections

open access: yesEarth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Deep learning (DL) models are increasingly used for climate downscaling, yet the impact of observational uncertainty on their performance remains poorly understood. Here we assess this effect by training ensembles of DL downscaling models using four independent gridded observational data sets over continental Spain that differ in source ...

Pseudo-two-girdles c-axis fabric patterns in a quartz-feldspar mylonite (Costabona granodiorite, Canigo massif)

open access: yes, 2012
An example of the relationship that exist between the preferred crystaliografic orientation of quartz grains and the attitude of the mylonite foliation of quartz-feldspar mylonites is described. These rocks are the result of the inhomogeneous deformation

Late Variscan metamorphic and magmatic evolution in the eastern Pyrenees revealed by U–Pb age zircon dating

open access: yes, 2016
Variscan migmatites cropping out in the eastern Pyrenees were dated together with Late Variscan plutonic rocks. Upper Proterozoic–Lower Cambrian series were migmatized during a thermal episode that occurred in the interval 320–315 Ma
