Prima filogenesi del genere Nyctereutes (Canidae, Carnivora): conferme e implicazioni
2019
Il cane procione, Nyctereutes procyonoides (Gray, 1834), è un canide di piccola taglia originario dell’Asia orientale e Giappone, diffusosi anche in Europa centro-orientale in seguito a introduzioni. La tassonomia di questo canide e le sue affinità filogenetiche rispetto ad altri membri della stessa famiglia sono state una fonte di dibattito scientifico. Ad esempio, recenti analisi cromosomiche suggeriscono la possibilità di separare le popolazioni del Giappone da quelle del continente in una specie diversa, N. viverrinus. Inoltre, sebbene filogenesi morfologiche basate su campioni attuali indicavano possibili relazioni tra Nyctereutes ed alcuni canidi sudamericani, p.e. Cerdocyon Hamilton-…
First Early Pliocene micromammal faunas from Venta del Moro (Cabriel Basin, Spain) : new data on the Messinian dispersal of Debruijnimys
2021
The localities of La Bullana 3 and LA Bullana 2B (Valencia, E Spain) have yielded remains of Apodemusgorafensis, Paraethomys aff. abaigari, Stephanomys dubari, Apocricetus barrierei, Sciuridae indet. and Asoriculus cf. gibberodon the former, and Apodemusgorafensis, Paraethomys aff. abaigari, Stephanomys dubari, Apocricetus barrierei, Sciuridae indet., Asoriculus cf. gibberodon, Castillomysgracilis, Occitanomysbrailloni, Occitanomys sp., Paraethomys meini, Ruscinomys sp., Eliomys intermedius, Debruijnimys cf. julii and Atlantoxerussp. the latter. Based on the study of these micromammal assemblages, we propose an Early Pliocene age (MN14) for both sites. The pres-ence a gerbilid related to De…
The southernmost Miocene occurrence of the last European herpetotheriid Amphiperatherium frequens (Metatheria, Mammalia)
2012
Abstract The present work provides for the first time a detailed description of teeth attributable to metatherians in the Miocene fossil record of Spain, and justifies their generic and specific ascription. The fossil elements found correspond to Amphiperatherium frequens, the last herpetotheriid that inhabited Europe. This is so far the southernmost occurrence of this species, thus showing that its geographic range extended further southward than previously thought.
A Biochronologic Subdivison of the European Paleogene Based on Mammals — Report on Results of the Paleogene Symposium Held in Mainz in February 1987
1990
In February 1987 the paleontologists working on European mammalian faunas of the Paleogene convened in Mainz to establish a mammal chronology for this time period. The results were edited by the author of this report at the end of the same year (Schmidt-Kittler, 1987). The biochronological subdivision agreed upon in this symposium corresponds to the general conditions met in the European continental Tertiary. Therefore, it is consistent with the concept of subdivision used for the Neogene mammal chronology of Europe elaborated in an earlier meeting in Munich (Fahlbusch, 1976).
Stratigraphic and structural relationships between Meso-Cenozoic Lagonegro basin and coeval carbonate platforms in southern Apennines, Italy
1999
Abstract Stratigraphic studies and facies analysis integrated with a new geological and structural survey of the Meso-Cenozoic units outcropping in the Campania–Lucania Apennines, southern Italy, allowed us to restore the palaeogeographic pattern and the tectonic evolution of the chain during Oligo-Miocene times. The southern Apennines are a N150°-striking and NE-verging fold-and-thrust belt mainly derived from the deformation of the African–Apulian passive margin. Four wide belts with different features have been recognized in the chain area. From east to west the following units outcrop: (a) successions characterized by basinal to marginal facies, ranging in age from Cretaceous to Miocene…
The chronology of the cercopithecoidea of East Africa
1987
The East African fossil record of cercopithecoids spans nearly 20 m. y. Throughout the Miocene Epoch, the diversity of monkeys was low, although at some localities the numbers of individuals is rather high. During the Plio-Pleistocene in contrast, there was a major radiation, or radiations of monkeys, involving both colobines and corcopithecines. A late Pleistocene to Recent radiation within the genusCercopithecus still seems to be under way. The history of diversity in the monkeys is in many ways a chronological inverted mirror image of the diversity history of the hominoid primates, which were highly diverse during the lower miocene, but became less diverse through time. The east african …
Pliocene-lower Pleistocene chronostratigraphy: A re-evaluation of Mediterranean type sections
1991
The Pliocene-Pleistocene stages defined for the Mediterranean region are generally used as the standard chronostratigraphic units for the upper Neogene and Quaternary. The recently developed calcareous plankton bio-chronology based on results from Ocean Drilling Program Leg 107 and numerous outcrop sections provides the necessary time control for evaluating the ages and stratigraphic relationships for the various Pliocene-Pleistocene stages and their associated stratotypes. Our results indicate that the currently accepted stratotypes do not provide a continuous stratigraphic representation for all of Pliocene-early Pleistocene time. On the basis of these findings, we propose a revised chron…
Tectono-climatic evolution of a Neogene intramontane basin (Late Miocene Carboneras subbasin, southeast Spain): revelations from basin mapping and bi…
2002
Exceptional 3-D exposures of fault blocks forming a 5km x 10 km clastic sediment-starved, marine basin (Carboneras subbasin, southeast Spain) allow a test of the response of carbonate sequence stratigraphic architectures to climatic and tectonic forcing. Temperate and tropical climatic periods recorded in biofacies serve as a chronostratigraphic framework to reconstruct the status of the basin within three time-slices (late Tortonian---early Messinian, late Messinian, Pliocene). Structural maps and isopach maps trace out the distribution of fault blocks, faults, and over time, their relative motions, propagational patterns and life times, which demonstrate a changing layout of the basin bec…
Argan oil prevents down-regulation induced by endotoxin on liver fatty acid oxidation and gluconeogenesis and on peroxisome proliferator-activated re…
2015
In patients with sepsis, liver metabolism and its capacity to provide other organs with energetic substrates are impaired. This and many other pathophysiological changes seen in human patients are reproduced in mice injected with purified endotoxin (lipopolysaccharide, LPS). In the present study, down-regulation of genes involved in hepatic fatty acid oxidation (FAOx) and gluconeogenesis in mice exposed to LPS was challenged by nutritional intervention with Argan oil. Mice given a standard chow supplemented or not with either 6% (w/w) Argan oil (AO) or 6% (w/w) olive oil (OO) prior to exposure to LPS were explored for liver gene expressions assessed by mRNA transcript levels and/or enzyme a…
