No full textThe Adamello-Brenta Natural Park bat community (Mammalia, Chiroptera): distribution and population status
No full textBats were censused in the Adamello-Brenta Natural Park (Trentino, central
Italian Alps) in May-September 1999 and 2000, by mist-netting and roost surveys. In all, 90
sites (19 caves, 50 buildings and 21 foraging sites), over an area of about 618 km2, were
checked. The bat species distribution in both the Park and the surrounding areas was obtained
by using field data, museum records and literature information. Atotal of 19 species was
recorded: of these, one (Myotis bechsteinii) was known from a museum collection and 18
were recorded in the field (Rhinolophus ferrumequinum, R. hipposideros, Myotis blythii, M.
daubentonii, M. emarginatus, M. mystacinus, M. nattereri, Pipistrellus kuhlii, P. nathusii, P.
pipistrellus, Nyctalus leisleri, Hypsugo savii, Eptesicus nilssonii, E. serotinus, Vespertilio
murinus, Barbastella barbastellus, Plecotus alpinus, P. auritus). Local distribution, habitat
use and body size parameters of the species were studied, and selection of roosts and foraging
sites by the bat community was analysed with logistic regression. The conservation status
of the bat community is also discussed. We document the third record of breeding by
Pipistrellus nathusii and the fourth Eptesicus (Amblyotus) nilssonii nursery in Italy, as well
as the first roosting sites of the recently described Plecotus alpinus

No full textFirst record of the alpine long-eared bat (Plecotus macrobullaris Kuzjakin, 1965) in Lombardy revealed by DNA analysis
No full textMitochondrial DNA sequencing of 63 samples of
bats from the genus Plecotus, from Lombardy and Trentino
Alto Adige, allowed us to determine for the first time the presence
of the new species Plecotus macrobullaris Kuzjakin,
1965, in Lombardy. This taxon has been recently described,
using genetic techniques, as a new species, also using tissue
samples from individuals captured in Trento Province, that represented
the first record in Italy. Recent taxonomic studies on
the genus Plecotus have revealed the presence of four cryptic
species in Italy: in addition to P. macrobullaris there are P. austriacus,
P. auritus, P. sardus, the only endemic Italian bat species.
Since no discriminant function based on morphometric
parameters is currently available, only genetic techniques allow
to discriminate exactly the different species. Mitochondrial
DNA sequencing allowed us to assign 18 out of 33 bats
(55%) of the genus Plecotus caught in Lombardy to P. macrobullaris,
the others to P. auritus. Moreover, four reproductive
roosts of P. alpinus were identified, all in buildings. The species
was never found in caves, in contrast with P. auritus.
The presence of this new species in Lombardy should activate
large-scale monitoring to define species distribution and habitat
preferences, finalised to define population status and conservation
strategies
