Full text linkItalian hare Lepus corsicanus De Winton, 1898, is a true species living in simpatry with Lepus europaeus in mainland Italy and with Oryctolagus cuniculus in Sicily, where L. europaeus is absent. Up to date, nobody has studied the helminths of this endemic Italian Mammal. Therefore, in order to describe Italian hare gastro-intestinal helminths, gastro-intestinal tract of 29 Italian hares, coming from mainland Italy (#14) and from Sicily (#15) were collected between 1997 and 2009. Twentyfive hares were positive for at least one parasite (86 %). Six parasite species were isolated, 2 cestodes (Cittotaenia pectinata, prevalence 3 %) and Paranoplocephala sp., 3 %) and 4 nematodes (Trichostrongylus retortaeformis, 86 %, Graphidium strigosum, 14 %, Trichuris sp., 10 % and Teladorsagia circumcincta, 7 %). Both Teladorsagia circumcincta circumcincta and Teladorsagia circumcincta trifurcata morphotypes were identified. Comparison with available data regarding L. europaeus and O. cuniculus in Italy is provided. Being not T. circumcincta and Paranoplocephala sp. typical parasites of leporids, a description of the ob¬served specimens is given
Intestinal helminths of the endemic Italian hare, Lepus corsicanus (De Winton, 1898), in Sicily (Italy)
No full textThe Italian hare (Lepus corsicanus De Winton, 1898) is endemic to central and southern Italy, where it lives in sympatry with Lepus europaeus in the mainland, while in Sicily L. europaeus is absent. The only report of endoparasites in L. corsicanus in Italy dates back to 2012. After a period of protection, the population density of the Italian hare in Sicily increased. This enabled new parasitological data to be collected on 27 hares which were compared with the data collected on 15 Sicilian hares from a previous study. Trichostrongylus retortaeformis, Paranoplocephala sp. and Cittotaenia (Mosgovoyia) sp. were isolated from the intestine. T. retortaeformis was the most prevalent and abundant parasite. Its abundance was significantly higher in males than in females. No age differences emerged. T. retortaeformis abundance was not related to low body mass and was significantly higher than that calculated from the data of the previous survey. At the same time aggregation, known as a regulatory factor of host-parasite relationship, was also higher in the present study. The possible biases introduced by sampling with different methods prevent any definitive conclusions. However, the relationship between L. corsicanus and its intestinal parasite biocoenosis appears to be stable and has possibly improved, in line with the improved status of the host population

No full textThe trial was carried out on 12 sympatric adult females: 6 Italian hares (Lepus corsicanus) and 6 Brown hares (Lepus europaeus). Colour characteristics were studied by CIEL*a*b* method on the following anatomical regions: forehead, subocular patch, nape, withers, rump, hind leg, knee, and belly. Differences between means were tested by t test. The most striking differences were observed in a* and in C indexes. Italian hares resulted more reddish in knee (5.22 vs. 3.93, P≤0.001) and in hind leg (2.96 vs. 1.34, P≤0.01) and less reddish (P≤0.001) in the regions of subocular patch (3.35 vs. 5.34), nape (3.24 vs. 6.05) and withers (3.25 vs. 4.81) than Brown hare. Colour saturation was lower (nearer to the grey) in the regions forehead (4.78 vs. 6.41 P≤0.01), subocular patch (8.91 vs. 11.24, P≤0.05), nape (4.82 vs. 10.56, P≤0.001), withers (4.63 vs. 8.91, P≤0.001), and rump (5.81 vs. 8.30, P≤0.05) and higher in the regions hind leg (11.07 vs. 4.46, P≤0.001), knee (15.45 vs. 11.14, P≤0.001), and belly (3.30 vs. 2.15, P≤0.05) in Italian hare than in Brown hare. These differences are consistent with colour pattern of coat described in literature
