Over the centuries, three main granitoid types have been used in Salamanca city, from the following localities: (1) Los Santos, (2) Martinamor, and (3) Villavieja de Yeltes. A systematic geological comparison of these three main granite types was carried out, including the following aspects: (i) magma emplacement (border of a large batholith; sill-like body; and late rooted pluton, respectively), (ii) geochemistry and petrogen...

Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...

This work presents a series of points of geological, cultural and archaelogical heritage that allow for the development of tourism routes in the most significant extractive area that supplied natural stone to the primary historical monuments of the city of Ávila, a World Heritage City. The conceptualization of this route is predicated on a multidisciplinary study encompassing an inventory of quarries, geological cartography, a...

Hybridization between widespread species and narrow endemics poses a serious conservation threat, often leading to extinction via genetic swamping. In this study, we applied an integrated approach—combining genetics, morphometrics, and functional ecology—to investigate the implications of hybridization between the widespread species Limonium cossonianum and the Critically Endangered L. estevei . We combined molecular markers (...

Building and ornamental stones are important elements of cultural heritage and geoheritage, hence the importance of its study. Vaugneritic rocks used in the city of Salamanca (World Heritage City, 1988) have been a singular building material during the Renaissance and Baroque periods. They come from a small pluton (1.5 km 2 ) with complex zoning, located about 40 km west of Salamanca. Petrographically, they are quart-zmonzodio...
