Changes in dip and frictional properties of the basal detachment controlling orogenic wedge propagation and frontal collapse: the External central Betics case [PDF]

open access: yes, 2016
Thin-skinned fold-and-thrust belts (FTBs) have been extensively studied through both field examples and modelling. The overall dynamics of FTBs are, therefore, well understood. One less understood aspect is the combined influence of across-strike changes

Decadal climate variability and increasing exposure of Chilean agriculture

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Central Chile has undergone a steady shift from traditional annual crops to fruit orchards and vineyards, and a decline in the area dedicated to annual crops. This transition coincides with a decrease in precipitation and an increase in temperature.

Sulfide mineralogy of igneous basic rocks (ophites) from the external zone of the Betic Cordillera [PDF]

open access: yesEuropean Journal of Mineralogy
The Triassic sedimentary rocks of the external zone of the Betic Cordillera in southern Spain host abundant igneous basic rocks (“ophites”) metamorphosed in the greenschist facies.

Seismic and tectonic interpretation of the ESCI-Béticas and ESCI-Alborán deep seismic reflection profiles: structure of the crust and geodynamic implications [PDF]

open access: yes, 1997
The seismic and tectonic interpretation of the ESCI-Béticas and ESCI-Alborán deep seismic reflection profiles provides an overall image of the crust on the northern flank of the Betic-Rif orogenic system.

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Natural Climate Solutions, Indigenous Peoples, Mestizos, and the Legacies of Conflict Over Land in the Ecuadorian Amazon

open access: yesRural Sociology, Volume 91, Issue 2, June 2026.
ABSTRACT Over the past two decades as global alarm over disruptive climate change has grown, coalitions of high‐ranking government officials and prominent activists have launched campaigns to protect and restore greenhouse gas absorbing rain forests. The initial results from these campaigns have varied dramatically across racial and ethnic landholding ...

Messinian productivity changes in the northeastern Atlantic and their relationship to the closure of the Atlantic-Mediterranean gateway: implications for Neogene palaeoclimate and palaeoceanography. [PDF]

open access: yes, 2016
The stable isotope composition of planktic and benthic foraminifera and the distribution of selected benthic foraminiferal species from a Messinian record of the lower Guadalquivir Basin, northeastern Atlantic Ocean, show that regional productivity ...

Crustal structure of the central sector of the Betic Cordillera (SE Spain) [PDF]

open access: yesTectonics, 1997
Deep seismic reflection, gravimetric, and magnetometric data allow the main features of the deep structure of the central sector of the Betic Cordillera to be established. The Moho is horizontal or dips slightly toward the S below the mountain chain, and its morphology has no direct relationship with the region's topography. The deep reflectors are not

Seismic Imaging Reveals Ongoing Modification of Craton Margins in Northeast Asia

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Cratonic margins are commonly modified, yet the processes responsible remain debated. The Korean Peninsula, situated between adjacent cratons, the Japan Trench, and a back‐arc system, provides a natural setting to investigate this problem. Using 4 years of dense seismic observations, we image upper‐mantle structure beneath the peninsula with P‐
