New records of bats in the Province of Trieste (Friuli Venezia Giulia Region), Northeastern Italy - In the Province of Trieste recent information on bats is lacking, with no significant information on bat fauna for more than 15 years. A short bat study was conducted on three days and nights in the end of July 2008. By implementing different research methods, we recorded at least nine bat species on six out of twelve localities, and observed signs of bat presence (droppings) at additional two. Six bat species were mistnetted: Hypsugo savii, Myotis bechsteinii, Myotis nattereri, Plecotus macrobullaris, Eptesicus serotinus and Barbastella barbastellus. The species or groups of species, that were detected with ultrasound detectors only, were Pipistrellus kuhlii/nathusii, Myotis sp. and Rhinolophus hipposideros, the latter near the probable cave roost. One individual of Rhinolophus ferrumequinum was observed at one cave. Three bat species (M bechsteinii, M nattereri and P macrobullaris) were recorded in the province for the first time. Reproduction of four species was confirmed, either by mistnetting lactating females (M. bechsteinii, M nattereri, H. savii) or juvenile individuals (E. serotinus). Despite very short time of research, gathered results indicate rich bat fauna in the province. Further study of bat distribution and ecology in the area would be necessary
Enhanced Glaucoma Staging System (GSS 2) for classifying functional damage in glaucoma
No full textPurpose: To introduce a new method, derived from the Glaucoma Staging System (GSS), for classifying glaucomatous visual field defects. Patients and Methods: Four sample groups composed respectively of 471 (sample #1), 128 (sample #2), 185 (sample #3), and 131 (sample #4) patients with either ocular hypertension or chronic glaucoma were considered. The GSS 2 uses both the MD and CPSD/CLV or PSD/LV perimetric indices to classify visual field defect in 6 stages and in 3 types (generalized, localized, and mixed). The formulas were determined using sample # 1. A new borderline stage was created, on the basis of sample #2. The relationship between the PSD/LV and CPSD/CLV values was studied on sample #3 to verify the possibility of using the uncorrected indices instead of the CPSD/CLV. The relationship with other classification methods was studied on sample #4. Results: The GSS 2 showed a strong level of association with the AGIS and the Hodapp-Parrish-Anderson methods in staging defect severity. A good correlation was also found with a classification based on the Bebie curve. Conclusions: The GSS 2 was able to correctly classify both damage severity and perimetric defect type in the sample studied, using either the corrected or uncorrected visual field indices. It is a quick and easy method, and its formulas can be introduced in any software
Genetic and morphometric comparison between Sorex arunchi Lapini and Testone, 1998, and other shrews from Italy
No full textThe results of allozymic, morphologic and morphometric studies performed on three parapatric shrews of the genus Sorex from northern Italy are presented. These data clearly indicate: (1) Sorex samniticus is genetically well differentiated from S. araneus and S, arunchi, displaying a high mean value of genetic distance in comparison with the other two species (D = 0.463). (2) S, araneus and S. arunchi display low values of genetic distance (D = 0.007) and the latter shows lower levels of genetic variability. Altough no fixed allele difference was observed, an exclusive allele (Lap-2(96)) is present in S. arunchi at low frequence, another one (Pgm-1(96)) is rare in S. araneus and quite frequent in S. arunchi, and several alleles (12) of S. araneus are missing in S. arunchi. In S. araneus some of these alleles are quite frequent. (3) Strong morphometric differences between S. araneus and S. arunchi permit to distinguish these parapatric shrews with great accuracy, also in some cases of marginal sympatry. These evidences support the hypothesis that S, arunchi might be a recent (end of Pleistocene-lower Holocene) relict of the subgenus Sorex s. s
