Ancient saltern metagenomics: tracking changes in microbes and their viruses from the underground to the surface
(Wiley, 2021-07)Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral ... -
Anisotropy of magnetic susceptibility of the Pyrenean granites
(Taylor & Francis, 2017)[EN]In this paper, we report on a compilation of more than 2200 sites (more than 10,000 individual measurements) where anisotropy of magnetic susceptibility (AMS) was studied in granites from the Variscan Pyrenees. The ... -
Aportaciones al conocimiento paleobiológico y cronológico de las poblaciones humanas de la Prehistoria reciente en el norte de la península ibérica
(2022-02-10)En esta tesis doctoral, el objetivo es estudiar la cronología y los restos humanos de tres yacimientos de los Pirineos Atlánticos Occidentales (Abittaga, Atxuri-I y Lumentxa) y de un yacimiento del complejo arqueo-paleontológico ... -
Application of Line of Sight and Potential Audience Analysis to Unravel the Spatial Organization of Palaeolithic Cave Art
(Springer, 2022-12)The endokarst landscape is the result of long erosion and sedimentation processes that have modelled an environment in which capricious forms abound. Despite being a hostile environment for human life, these caves must ... -
Assessment of long-term structural movements in a historic cliffside construction through Lomb-Scargle spectral analysis of unevenly spaced time records: the Punta Begona Galleries (Getxo, Spain)
; ; ; ; Morales Juberías, Tomás (Springer, 2022)
Long-term monitoring of structural movements in historic buildings and heritage sites allows assessing their stability and recognizing damages that require intervention. The Punta Begona Galleries, built in the earlier ... -
