Morphological variation in a secondary contact between divergent lineages of brown trout (Salmo trutta) from the Iberian Peninsula

open access: yesGenetics and Molecular Biology, 2009
The aim of this study was to analyze the morphological variation of brown trout (Salmo trutta) in the Duero basin, an Atlantic river basin in the Iberian Peninsula, where a spatial segregation of two divergent lineages was previously reported, based on ...

Conservation Challenges Under Taxonomic Uncertainty: Introgression Patterns and Environmental Correlates in Mediterranean Brown Trout

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The Mediterranean brown trout (Salmo trutta species complex) comprises genetically and ecologically distinct lineages primarily distributed across the Western Mediterranean region. Conservation of the Mediterranean brown trout is complicated by unresolved taxonomy.

Petrophysical characterization of the Dolomitic Member of the Boñar Formation (Upper Cretaceous; Duero Basin, Spain) as a potential CO2 reservoir

open access: yesEstudios Geologicos, 2016
Boñar Formation (Upper Cretaceous) is a mainly carbonate succession, which outcrops in the North of Duero Basin (Spain). According to the existing data, the Dolomitic Member of this formation appears to be the most suitable for geological storage of CO2.

New remains of Titanochelon richardi (Testudines, Testudinidae) from the Upper Miocene of the Vallès‐Penedès Basin: taxonomic and phylogenetic implications

open access: yesPapers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The alpha‐taxonomy of continental giant tortoises (Testudinidae, Titanochelon) from the European Neogene is far from settled, which has implications for inferring their phylogenetic relationships. The diagnosis of the type species (Titanochelon bolivari) is dubious because it considered Titanochelon richardi as a junior subjective synonym ...
