New lithostratigraphy for the Cantabrian Mountains: A common tectono-stratigraphic evolution for the onset of the Alpine cycle in the W Pyrenean real…
2019
The Pyrenean-Cantabrian Orogen arose through the collision of the Iberian and Eurasian plates, mostly in Cenozoic times. This orogen comprises two main mountain ranges, the Pyrenees to the east, and the Cantabrian Mountains to the west. To date, the early Alpine tectono-sedimentary phases preserved in the Cantabrian Mountains, of Permian and Triassic age, have been considered independently from the same phases in neighbouring basins of SW Europe, and even from the eastern part of the same orogeny (the Pyrenean orogeny). In consequence, the beginning of the Alpine cycle in the Cantabrian Mountains has been interpreted within a specific geodynamic context, far from the general evolutionary ph…
Tectonothermal Evolution of the Broadly Rifted Zone, Ethiopian Rift
2019
The Broadly Rifted Zone (BRZ) of southern Ethiopia is a long-lived and structurally complex segment of the East African Rift System. However, due to poor surface exposure of early synrift strata and a dearth of subsurface data, the evolution of the BRZ remains poorly understood. We present new apatite (U-Th-Sm)/He and augmented apatite fission track low-temperature thermochronology data from the Beto and Galana basin boundary fault systems to constrain the tectonothermal evolution of the western and eastern BRZ, respectively. Time-temperature reconstructions suggest that East African Rift System-related extension began concurrently across the BRZ in the early Miocene (20–17 Ma), at least 6 …
SIGNIFICANCE FOR INTERNATIONAL CORRELATION OF THE PERAPERTÚ FORMATION IN NORTHERN PALENCIA, CANTABRIAN MOUNTAINS. TECTONIC/STRATIGRAPHIC CONTEXT AND …
2021
Small ammonoid assemblages are recorded from the Perapertú Formation in northern Palencia. This is a mudstone unit with local platform limestones characterised by carbonate debris flows on the limestone margins. This unit, of Late Bashkirian to Early Moscovian age, participates in a series of southwards verging thrust slicesNorth of a major fault zone which originated as the head (leading edge) of a large thrust sheet with an internal deformation consisting of thrust slices and at least one nappe structure. Opposed vergencies at the head of this major thrust sheet (Carrionas Thrust Front) and the Ruesga Fault which locally modifies its trace, mark the position where the northern branch of t…
Sudeckie linie życia. O "Grandhotelu" Jaroslava Rudiša
2012
Powieść Grandhotel to utwór czeskiego pisarza młodego pokolenia Jaroslava Rudiša. Portrety i losy bohaterów powieściowych zostały wpisane przez Rudiša w dwudziestowieczną historię Liberca i sudeckich okolic. Stworzenie postaci Fleischmana – głównego bohatera powieści, o skomplikowanej osobowości i tożsamości – posłużyło pisarzowi w próbie zdiagnozowania zbiorowego ducha współczesnych Czechów. Z powieściowego świata Grandhotelu wyłaniają się dwa zasadnicze wymiary: egzystencjalny z całą galerią indywidualności poszukujących swojego miejsca na ziemi, z ich pogmatwanymi „liniami życia” i osobistymi dramatami; oraz zbiorowy, historyczno-społeczno-kulturowy, wypełniony skomplikowanymi dwudziesto…
Hydrophytic vegetation aspects in the Nebrodi mountains (Sicily)
2009
The vegetation of damp areas in the Nebrodi Natural Park was already surveyed in some studies (Brullo et al. 1994). In particular, the various hygro and hydrophytic aspects were referred to associations belonging to the Phragmitetea and the Potamogetonetea classes respectively. Small lacustrine habitats in Sicily have disappeared almost everywhere and are conserved still today only in the Nebrodi Mountains. They host widely distributed hydrophytes. Some of these plants are rather localized in Sicily, e.g. Potamogeton polygonifolius Pourr. and Utricularia australis R. Br. The latter occurs also in the Madonie Mountains. Recent analyses revealed some hollows characterized by an accentuated re…
Zmiany struktury przestrzennej krajobrazu na obszarze Parku Krajoznawczego "Góry Owawskie" w okresie od XIX do XXI w
2021
Krajobrazy gór i przedgórza podlegają wielu przemianom warunkowanym przez czynniki antropogeniczne oraz przyrodnicze. W Parku Krajobrazowym „Góry Opawskie” i jego otulinie w okresie od XIX do XXI w. doszło do szeregu przekształceń krajobrazowych, związanych z rozwojem sieci osadniczej, zmianami zasięgu kompleksów leśnych oraz zmianami w strukturze upraw. Kluczowe było także objęcie ochroną prawną tego obszaru i utworzenie parku w 1988 r. W artykule dokonano analizy zmian w strukturze krajobrazu z użyciem metryk krajobrazowych, które wykorzystano odrębnie do oceny zmian krajobrazu jako całości oraz poszczególnych klas. Badania przeprowadzono na podstawie obrazów odtworzonych z archiwalnych ź…
Do nutritional supplements have a role in age macular degeneration prevention?
2013
Purpose. To review the proposed pathogenic mechanisms of age macular degeneration (AMD), as well as the role of antioxidants (AOX) and omega-3 fatty acids (ω-3) supplements in AMD prevention.Materials and Methods. Current knowledge on the cellular/molecular mechanisms of AMD and the epidemiologic/experimental studies on the effects of AOX andω-3 were addressed all together with the scientific evidence and the personal opinion of professionals involved in the Retina Group of the OFTARED (Spain).Results. High dietary intakes ofω-3 and macular pigments lutein/zeaxanthin are associated with lower risk of prevalence and incidence in AMD. The Age-Related Eye Disease study (AREDS) showed a benefic…
Beyond Hunting Camps: Early Holocene Occupations in High Cantabrian Mountains (Spain)
1998
En la comunicación se presentan los resultados de las excavaciones en el abrigo de La Calvera (Camaleño, Cantabria) incluyendo un conjunto de nuevas dataciones radiocarbónicas y se hace una reflexión sobre la ocupación de las montañas cantábricas al comienzo del Holoceno. In the communication the results of the excavations in La Calvera rock shelter (Camaleño, Cantabria) are presented, including a set of new radiocarbonic dates and a reflection is made on the occupation of the Cantabrian mountains at the beginning of the Holocene.
Land Snail Communities in Limestone Gorges from the Southern Part of the Metaliferi Mountains (Apuseni Mountains, Romania)
2018
Abstract This study focuses on terrestrial gastropod communities in a karst area, where the presence of water and the limestone generates favourable environment for land snails. Three limestone gorges were analysed located in the southeast of the Metaliferi Mountains. Four different habitats in three limestone gorges were analysed – Glodului, Cibului and Mada. A total of 42 species of land snails were identified. The terrestrial gastropod communities in the area are dominated by calciphile species, such as Granaria frumentum, Truncatellina cylindrica and Alopia bielzii madensis. The differences between the analysed habitats are not pronounced enough to be reflected in the structure of the s…
