AMMONOID EVOLUTION TRIGGERED BY PALAEOGEOGRAPHIC CHANGES: ORIGIN OF OXFORDIAN SUBFAMILY PASSENDORFERIINAE (SOUTHERN TETHYS)
2011
The comparison of Middle-Upper Jurassic ammonite successions in SW Sicily (Sciacca) and Iberia shows that, during the Middle Jurassic, besides some typical Mediterranean taxa, in Sicily as well as in the Betic Ranges (S Spain) ammonoid successions contain a higher share of typical Submediterranean taxa of Ammonitina, entirely comparable to those recorded in Epicontinental areas of Eastern Iberia. From middle Oxfordian onwards instead, ammonite successions show a clear taxonomic differentiation, being dominated in Sicily by typically Mediterranean taxa (Passendorferiinae) whilst typical Submeditrerranean groups (Perisphinctinae, Oppeliidae) clearly dominant in the Iberian Range, are testimon…
Holocene interaction of maritime and continental climate in Central Europe: New speleothem evidence from Central Germany
2019
Central European climate is strongly influenced by North Atlantic (Westerlies) and Siberian High circulation patterns, which govern precipitation and temperature dynamics and induce heterogeneous climatic conditions, with distinct boundaries between climate zones. These climate boundaries are not stationary and shift geographically, depending on long-term atmospheric conditions. So far, little is known about past shifts of these climate boundaries and the local to regional environmental response prior to the instrumental era.\ud \ud High resolution multi-proxy data (stable oxygen and carbon isotope ratios, S/Ca and Sr/Ca) from two Holocene stalagmites from Bleßberg Cave (Thuringia) are used…
Coprolites in natural traps : direct evidence of bone-eating carnivorans from the Late Miocene Batallones-3 site, Madrid, Spain
2021
We describe two carnivoran coprolites found in the pseudokarst natural carnivore trap of Batallones-3, from the Late Miocene of Spain. The larger one, comprising multiple indistinguishable fragments of broken and corroded bones, indicates that the producer of the dropping might have been highly capable of crushing the softer parts of large bones. On the other hand, the smaller one shows several relatively larger and more complete bone fragments, thus exhibiting a greater capacity to break and swallow large portions of bone. The external morphology of the large coprolite is similar to that of extant bears, whereas the smaller one more closely resembles that of the living insectivorous hyaeni…
Vegetation and climate in the eastern Iberian Peninsula during the pre-evaporitic Messinian (late Miocene). Palynological data from the Upper Turolia…
2015
International audience; The present paper reports a complete palynological study of the Upper Turolian sediments outcropping at the Venta del Moro site (eastern Iberian Peninsula). The pollen assemblages observed mainly reflect the local and regional vegetation, which must have formed part of a wetland ecosystem within a general setting of open steppe, as indicated by the great abundance and diversity of herbaceous pollen. This reflects the persistence of open vegetation in the Iberian Peninsula after the Middle Miocene when it became extensive. We here report the most recent record of Disanthus for the Iberian Peninsula. This shrub played an important role in an unusual, edaphically-mediat…
Detection of archaeological forgeries of Iberian lead plates using nanoelectrochemical techniques. The lot of fake plates from Bugarra (Spain)
2014
Identification of forgeries is of considerable interest in studies of archaeological signariums and written Iberian artifacts, elements of capital importance for the knowledge of that culture, because there are many Iberian inscribed lead plate counterfeits circulating in the market and among many museum funds. A case study of identification of forgeries of archaeological lead using voltammetry of microparticles (VMP) and scanning electrochemical microscopy (SECM), aided by conventional optical microscopy and scanning electron microscopy (SEM/EDX) is described. The electrochemical methods are essentially non-invasive so can be applied to samples of nanoscopic size. Application to the authen…
Nota sobre tortrícidos ibéricos del género Pammene Hübner, [1825] (Lepidoptera : Tortricidae)
2006
Se dan a conocer dos especies de Tortricidae (Olethreutinae, Grapholitini) del género Pammene Hübner, [1825]: P. obscurana (Stephens, 1834) y P. suspectana ([Lienig] & Zeller, 1846). Éstas se diagnosticaron mediante el estudio de la genitalia de ejemplares masculinos capturados en Cataluña en trampas delta de base pegajosa, cebadas con feromona sexual de Cydia pomonella (Linnaeus, 1758) y de Grapholita molesta (Busck, 1916). La primera es nueva para Cataluña (España); la segunda lo es para la fauna íbero-balear. Two species of Tortricidae (Olethreutinae, Grapholitini) belonging to the genus Pammene Hübner, [1825]: P. obscurana (Stephens, 1834) and P. suspectana ([Lienig] & Zeller, 1846) are…
A new taxonomic arrangement in "Linaria" sect. "supinae" ("Antirrhineae")
2008
Como resultado de un estudio macromorfológico y de los caracteres seminales de Linaria benitoi Fern. Casas, endemismo de los alrededores del Cabo de Gata (SE Península Ibérica) y de los táxones del grupo de L. oblongifolia, se discuten la variabilidad y las relaciones morfológicas de este conjunto de plantas. Así, se propone la siguiente nueva combinación: Linaria oblongifolia subsp. benitoi (Fern. Casas) L. Sáez, M.B. Crespo, Juan & M. Bernal, comb. & stat. nov. As a result of a study of macromorphological and seed features of Linaria benitoi Fern. Casas, endemic to Cabo de Gata (SE Iberian Peninsula) and taxa included in the L. oblongifolia group, the variability and morphological relatio…
Coprology of Panthera tigris altaica and Felis bengalensis euptilurus from the Russian Far East
2007
Fecal samples from the Siberian tiger (Panthera tigris altaica) and the Amur cat (Felis bengalensis euptilurus) from Far Eastern Russia, were examined for parasites. A natural sedimentation methodology was used and a complete examination of all the sediment was performed. This fecal investigation allowed us to isolate and identify several developmental stages of gastrointestinal, hepatic, and respiratory parasites. Five parasites were found from P. t. altaica: 11 trematodes (Platynosomum fastosum) and 4 nematodes (Strongyloides sp., Ancylostomatidae, Toxascaris leonina, and Toxocara cati). Five parasites were found from F. b. euptilurus: 1 cestode (Diplopylidium sp.) and 4 nematodes (Trichu…
Contagion of Uncertainty: Transmission of Risk from the Cryptocurrency Market to the Foreign Exchange Market
2019
Earlier research documented that cryptocurrencies, including Bitcoin, have experienced dramatic fluctuations in both market capitalization and market share in recent years. Unsurprisingly, Bitcoin returns exhibit higher volatility than traditional G-10 currencies. Our paper extends earlier research and investigates the potential impact of news originating from the Bitcoin market. Confirming earlier studies, we find that Bitcoin exhibits dramatically higher volatility than the dollar factor. Surprisingly, our findings indicate that only hacking incidents that occur in the Bitcoin market result in high levels of co-movement in the risk of both markets the cryptocurrency and the G-10 currency …
Paleoecología y cultura material en el complejo tumular prehistórico del Castillejo del Bonete (Terrinches, Ciudad Real).
2015
[EN] Castillejo del Bonete is a tumulus complex located on the southern edge the Iberian Plateau, occupied during Chalcolithic and Bronze Age periods, and linked to the Culture known as Motillas. Diverse archaeological objects have been recovered in association with their architectures (barrows, corridors, walls, etc.). Based on charcoal, pollen and microvertebrates a paleoecological study will be discussed. Furthermore, the analysis of different materials such as wood, shell, stone and ivory ornaments together with pottery vessels and metallic objets will also be carried out. All this evidence could be related to feasting practices and offerings
