The caves of the Mount Fenera and their fauna. During five years (2011-2015) the natural cavities of the Mount Fenera (Valsesia, northeastern Piedmont, Italy) have been reviseted and tagged with aluminium plaques by the authors. The itinerary, the accessibility and the updated fauna list of each of the 81 known caves are given. The cavities are lis...

After a short illustration of the main geological as well as climatic and vegetational features of the Sesia Valley, a synthesis of the researches carried out so far in this area is reported. A topographic catalogue of the 249 Tiger beetle and Ground beetle
species recorded from this territory is provided, with notes regarding the ecology and distribution of the most interesting ones. Furthermore, the main observed assemblages are described.
... We carried out systematic recordings of bat calls at cave entrance and three other habitat types (wood, dark open mosaic, open mosaic with light) to better understand the importance of these habitats for bats. We examined the Monte Fenera Natural Park area, in NW Italy, which includes 81 caves (Lana & Sella, 1986). Previous biospeleological surveys conducted by Gruppo Speleologico Biellese C.A.I. (GSBi-CAI) from 1993 to 1999 reported the presence of Mouse-eared bats Myotis myotis/blythii, Lesser Horseshoe bats Rhinolophus hipposideros and Greater Horseshoe bats Rhinolophus ferrumequinum not only inside the major caves of the massif but also in several small cavities (Pascutto & Balestrieri, 2001). ...
Caves play an important role in bat ecology, offering natural roosting and wintering sites. In the reproductive period, bats need to fi nd an effective foraging environment away from the cave entrance, but only few studies have considered the use of foraging habitats in the immediate proximity of the caves. We provide a list of 18 bat species and 5 bat acoustic groups observed in a system of 81 caves in NW Italy. Winter censuses carried out during 17 years showed an increase of the Greater Horseshoe bat, a species of conservation concern. In the summer period this rare species was also observed
foraging in nearby areas. Recording of bat calls in the summer period was performed both at cave entrances and in three foraging habitats present in the area surrounding the cave (woods, agricultural mosaic with artifi cial light, dark mosaic). Light mosaics and woods showed the highest foraging activity (160.3 and 72.0 pass/hour), while woods and cave entrances were accessed by the largest number of bat species. Our survey improves the inventory of bat species in a poorly sampled area, and we recommend a reduced tourism access, thereby promoting preservation of bats.
... A frequently misidentified species only occurring in Alpine and pre-Alpine area, from the Pennine to the Julian Alps and in the Karst (Manganelli & Giusti, 1998;Dalfreddo et al., 2000;De Mattia, 2003;Dalfreddo, 2005). In NW Italy it only occurs east of the Dora Riparia river (Bishop, 1976a;Eikenboom, 1996;Manganelli & Giusti, 1998;Pascutto, 1998;Lana et al., 2016;Lana & Sella, 2016) Oxychilus gardinii Manganelli, Bodon & Giusti, 1991. Endemic species with narrow range limited to western Ligurian Apennines (Savona province) (Manganelli et al., 1991) and southern Piedmont (Alessandria province) (unpublished personal data). ...

This checklist of terrestrial, freshwater and brackish-water molluscs of Piedmont,
Valle d’Aosta and Liguria (NW Italy) is based on literature and museum data and on research by the authors and co-workers carried out until the end of 2020. The malacofauna consists of 394 taxa (280 land and 114 aquatic molluscs), 308 for Piedmont (225 land and 83 aquatic), 139 for Valle d’Aosta (120 land and 19 aquatic) and 274 for Liguria (193 land and 81 aquatic) and includes 24 undetermined or undescribed species and 44 endemics, 27 of which have a very narrow range. Three species are particularly localized: Iglica pezzolii Boeters, 1971, and Chondrina feneriensis Bodon, Nardi, Cianfanelli & Kokshoorn, 2015, limited to Monte Fenera (Novara and Vercelli provinces), and Falkneria camerani (Lessona, 1880), known from a few localities in the Pennine Alps. Seven taxa, recorded in the past, were no longer found: Eupaludestrina stagnorum (Gmelin, 1791), Marstoniopsis insubrica (Küster, 1853), Orcula dolium dolium (Draparnaud, 1801), Leucostigma candidescens (Rossmässler, 1835), Zonites algirus (Linnaeus, 1758), Cochlicella conoidea (Draparnaud, 1801) and Pisidium moitessierianum Paladilhe, 1866. Several species are of conservation interest according to the European Red List of non-marine molluscs and the IUCN Red List of terrestrial gastropods: one of these, Renea bourguignatiana Nevill, 1880, present in Italy in a few sites near Ventimiglia, is considered Critically Endangered; five others are reported as Endangered and 13 as Vulnerable. Among the threatened species, two have a very narrow range: Alzoniella delmastroi Bodon & Cianfanelli, 2004, limited to the Turin area and Pezzolia radapalladis
Bodon & Giusti, 1986, known only in eastern Liguria from Recco to Rapallo (Genoa province). Finally 46 entities are aliens, including three recently reported in Italy: Zonitoides arboreus (Say, 1817), Boettgerilla pallens Simroth, 1912 and Deroceras sturanyi (Simroth, 1894).

This volume reports the results of a study on the malacofauna of the Valle di Susa conducted between 1997 and 2006 on the basis of data from the literature, museums and field research. Known malacofauna consists of 159 species (121 land and 38 freshwater snails).
The list of species includes reports new for Piedmont and for Italy: two are probably undescribed species (Lehmannia sp. and Deroceras sp.) and two are new for Italy (Boettgerilla pallens and Trochoidea geyeri), though T. geyeri was previously collected and assigned to a new taxon (Helix caturigia Pollonera, 1889), later considered a subspecies of Candidula unifasciata. Two species (Truncatellina claustralis and Xerolenta obvia) are new for Piedmont and nineteen others for the province of Turin.
Finally, as far as the Valle di Susa is concerned, 35 land and 9 freshwater species are recorded for the first time. Museum material confirms the historical report of Vertigo genesii from Moncenisio Lake, which is therefore a species new for France.
Historically recorded species no longer found include three land (Vertigo genesii, Trochulus cf. plebeius and Petasina edentula) and two freshwater species (Viviparus contectus and Segmentina nitida).
