The Abruzzo-Apulian (Central and Southeastern Italy) fossil fauna, new challenges for paleontologists and paleobiogeographers
2012
The Abruzzo-Apulian Platform was an endemic Neogene paleobioprovince. Its relics can be found at the south-east of the Italian Peninsula. Geological and paleontological traces of this past land crop out both in the central Apennines, Maiella (Scontrone fossiliferous site), as well as in the Gargano Promontory. The Scontrone paleofauna -Scontrone is placed on the southern borderline of the Abruzzo National Park, Central-Southern Apennine. The bone-bearing sediments are coastaltidal-flat calcarenites stratigraphically dated to the Lower Tortonian. They yielded remains of terrestrial mammals, which include the bizarre ruminant Hoplitomeryx and the giant insectivore Deinogalerix, of a large ter…
The spreading of the invasive italian wall lizard on Vulcano, the last island inhabited by the critically endangered aeolian wall lizard
2018
[EN] The Aeolian Wall Lizard (Podarcis raffoneae) is an endemic species of the Aeolian Archipelago of Italy (Mediterranean Sea). Its distribution is limited to three islets and two relict populations on a relatively large island: Vulcano (a population on the summit of Gran Cratere volcano and another on Capo Grosso promontory). The critically endangered Aeolian Wall Lizard is threatened by the introduction of the Italian Wall Lizard (Podarcis siculus), which successfully competes and hybridizes with the endemic lizard. The invasive lizard is widespread on Vulcano, although the literature does not provide the exact distribution. Our first aim was updating the distribution of the Italian Wall…
A new small mammal assemblage from the M013 Terre Rosse fissure filling (Gargano, South-Eastern Italy)
2013
Abstract The taxonomic study of the small mammal assemblage from fissure M013, sampled by a team of the University of Torino during the 2005–2009 excavations in the Dell’Erba Quarry (Apricena, Foggia) is presented. The assemblage includes the Echinosoricinae Apulogalerix cf. pusillus and the Crocidosoricinae ?Lartetium cf. dehmi; the Myomiminae species Stertomys simplex and Stertomys lyrifer; a new genus and species of Cricetodontinae and a single specimen of Hattomys cf. nazarii. Muridae include Mikrotia cf. parva, Mikrotia sp. 1 and a new genus and species of Murinae, phylogenetically related to Mikrotia. The occurrence of the new Murinae, the new Cricetodontinae, the two species of gliri…
Apulogalerix pusillus nov. gen., nov. sp., the small-sized Galericinae (Erinaceidae, Mammalia) from the ‘‘Terre Rosse’’ fissure filling of the Gargan…
2013
Abstract A small moonrat belonging to the Galericini tribe occurs in all the assemblages from the Terre Rosse fissure fillings of the Gargano. It was first mentioned in the pioneering report of Freudenthal and by Butler in his study of the “gigantic” Deinogalerix, and has been quoted with different names several times in faunal lists of the Terre Rosse endemic faunas. Up to date, however, the description of this gymnure has never been achieved. We present here the taxonomical and morphological description of a sample from Fissure Filling F32 that is considered to document the youngest phase of population of the Gargano Paleoarchipelago. The comparisons with genera Galerix, Parasorex and Sch…
New insular taxa from the oldest Terre Rosse fissure filling (Gargano, Southeastern Italy).
2012
A rich amount of fossil remains of a highly diversified vertebrate fauna, known as “Mikrotia fauna”, has been retrieved from the red soil deposits (Terre Rosse) which fill the extensive palaeokarst network that affects the Mesozoic limestone along the north-western slopes of Mount Gargano (Southern Italy). The faunal assemblages reveal a rather complex history of bioevents such as dispersals and extinctions, which occurred when the area was isolated. These reconstructions were based on the materials collected during the seventies and the eighties of the last century. Forty years after its discovery, the Gargano Terre Rosse finally yielded evidence of an older faunal settlement. The peculiar…
Oral lichen planus, hepatitis C virus, and HIV: no association in a cohort study from an area of high hepatitis C virus endemicity
2004
Abstract Objectives We sought to assess the age-specific prevalence of oral lichen planus (OLP) in Mediterranean patients with chronic hepatitis C virus (HCV) and to evaluate the features of OLP in relation to sex, smoking, HCV genotype, HIV-1 coinfection, and antiviral treatments. Methods In all, 178 anti-HCV-positive adults (60 women and 118 men; age range 20-66 years) recruited from two cohorts (104 HIV-negative patients and 74 patients with HIV coinfection) underwent oral examination. Results Overall prevalence of OLP was 2.8% (5 of 178) (male/female ratio 0.2; odds ratio=0.119; 95% confidence interval=0.013-1.106), only among HIV-negative participants, always in the reticular pattern, …
Karyological and dental identification of Microtus limnophilus in a large focus of alveolar echinococcosis (Gansu, China).
1999
International audience; A study of voles (Arvicolidae, Rodentia) from Gansu (China) designed to identify a potential host of Echinococcus multilocularis, responsible for human alveolar echinococcosis, leads to a general analysis of Microtus limnophilus population karyotypes, M1 of M. oeconomus populations from all of Eurasia and of M. limnophilus of Mongolia. The Microtus of Gansu belonging to the nominal subspecies M. limnophilus limnophilus (2n = 38; NF = 58) differs markedly in size and shape of M1 from the M. limnophilus of Mongolia, which must therefore be considered as a new subspecies M. limnophilus of malygini nov. ssp. (2n = 38; NF = 60) and the M. oeconomus of Mongolia should be r…
ENDEMIC HANTAVIRUS INFECTION IMPAIRS THE WINTER SURVIVAL OF ITS RODENT HOST
2007
The influence of pathogens on host fitness is one of the key questions in infection ecology. Hantaviruses have coevolved with their hosts and are generally thought to have little or no effect on host survival or reproduction. We examined the effect of Puumala virus (PUUV) infection on the winter survival of bank voles (Myodes glareolus), the host of this virus. The data were collected by monitoring 22 islands over three consecutive winters (a total of 55 island populations) in an endemic area of central Finland. We show that PUUV infected bank voles had a significantly lower overwinter survival probability than antibody negative bank voles. Antibody negative female bank voles from low-densi…
Orthoptera Tettigoniidae as indicators of biodiversity hotspots in the Guinean Forests of Central and West Tropical Africa
2021
The present paper has two aims: 1) to present the results of the study of selected species of Orthoptera Tettigoniidae collected in the Guinean forests of West Africa and in the important hotspot of Dzanga-Ndoki National Park (Central African Republic); 2) to carry out a check-list of six subfamilies of Tettigoniidae (Pseudophyllinae, Conocephalinae, Hexacentrinae, Phaneropterinae, Mecopodinae and Hetrodinae) living in Central-West tropical Africa, in particular in two main tropical forests, in the subregion of upper Guinea, and in the subregion Nigeria-Cameroon plus the biodiversity hotspots of Central African Republic and Gabon. Many new records are reported and the following new species …
