Crustal structure variations in the southern Central Iberian Zone: effects of composition and Alpine reactivation in an internal Variscan domain

, 2017
The IBERSEIS and ALCUDIA projects have acquired vertical incidence and wide-angle reflection seismic data in the Variscan Central Iberian Zone of Spain.

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

A reassessment of the Lochkovian, Lower Devonian, benthic faunas and palynomorphs from the Dornes region, southern Central Iberian Zone, Portugal [PDF]

, 2008
A revision of benthic faunas and palynomorphs previously described from the Dornes syncline, southern Central Iberian Zone, Portugal, complemented with recent research, shows that the Serra de Luação Formation is of Lochkovian age. The systematics of

Thickening vs. extension in the Variscan belt: P–T modelling in the Central Iberian autochthon

, 2016
The Variscan tectonothermal structure of the NW and Central Iberian Massif shows an important thickening during the Early Carboniferous, prior to its thermal weakening and gravitational collapse in the Middle Carboniferous, triggering the uplift of its ...

Isotopic geochronology of granitic rocks from the Central Iberian Zone: comparison of methodologies

, 2010
En el plutón de Castelo Branco, se distinguen cinco granitoides, dispuestos concéntricamente de núcleo a borde del plutón. Las edades U-Pb-Th obtenidas en cristales de monacita por microsonda electrónica en estos granitoides son similares entre sí y varían entre 297 y 303 Ma.

First record of young‐of‐the‐year smooth hammerhead (Sphyrna zygaena) in coastal waters of Galicia, northwest Spain

Journal of Fish Biology, EarlyView.
Abstract The smooth hammerhead (Sphyrna zygaena) is typically considered an oceanic species and is only rarely observed in the cooler coastal waters of the northeastern Atlantic. On 20 December 2024, a juvenile S. zyganea was captured at 25 m depth in the inner Ría de Pontevedra (Rías Baixas, northwest Spain).

Crustal and Upper Mantle Structural Constraints on the Topography of the southern Central Iberian Zone

, 2014
Multi-seismic experiments ALCUDIA which include normal incidence and wide-angle seismic reflection data reveal detailed crustal and lithospheric structure of the central to the southwestern Iberia. The experiments provided an opportunity to analyse the nature and possible origin of the Mohorovicic discontinuity and map in cross-section the distribution
