Late Pliocene and Pleistocene small mammal chronology in the Italian peninsula

2007

The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polonicus. The Late Villanyian localities are well characterized with M. pliocaenicus, M. pitymyoides and M. tigliensis. The older part of the Early Biharian is documented by assemblages containing Microtus (Allophaiomys) ex gr. pliocaenicus, M. pusillus, M. cf. ostramosensis and M. tornensis, while the l…

A new small mammal assemblage from the Pirro 12 “Terre Rosse” fissure filling (Gargano, Southeastern Italy).

2011

The Pirro 12 fissure filling has been discovered and sampled by a team of the University of Torino during the 2005 field survey in the Dell’Erba Quarry (Apricena, Foggia). The occurrence of a very small Deinogalerix and of a very simple Mikrotia supported, at a first glance, the very old position of Pirro 12 in the biochronological succession of endemic faunal settlements of Gargano (Villier, 2011). In this communication the preliminary result of taxonomic studies of the small mammal assemblage of the Pirro 12 filling is presented. The Gliridae is by far the most common family in this site. Two species of the endemic genus Stertomys have been identified: the small-sized Stertomys cf simplex…

Distinct bhaplotype structure at the innate immune receptor Toll-like receptor 2 across bank vole populations and lineages in Europe

2015

Abstract: Parasite-mediated selection may contribute to the maintenance of genetic variation at host immune genes over long time scales. To date, the best evidence for the long-term maintenance of immunogenetic variation in natural populations comes from studies on the major histocompatibility complex (MHC) genes, whereas evidence for such processes from other immune genes remains scarce. In the present study, we show that, despite pronounced population differentiation and the occurrence of numerous private alleles within populations, the innate immune gene Toll-like receptor 2 (TLR2) displays a distinct haplotype structure in 21 bank vole (Myodes glareolus) populations across Europe. Haplo…

Primer estudio experimental sobre los efectos de la digestión en restos esqueléticos de murciélagos (Mammalia: Chiroptera)

2018

Taphonomic studies dealing with small mammals do not usually consider bats. Therefore, the degree to which bat bones are modi? ed by predation and other taphonomic agents are largely unknown. Here we present the results obtained from a set of experiments developed to approach this issue, focusing initially on the e?ect of digestion. For this purpose several bat bones and teeth were exposed to HCl and to two di?erent proteolithic enzymes. The experiments showed that bat bones are altered by acidic and enzymatic attack in a similar way as the bones of other small mammals. However, some patterns were observed in the teeth that had not been previously described in other groups. Thus, both the i…
