“…Concerning the third assumption, it is known that parasite transmission rates can be affected by moisture availability (Hulbert and Boag, 2001;Wilson et al, 2001). Previously, N. zembrae had only been recorded in the Iberian Peninsula and Zembra Island, where it occurs only in rabbits and in Iberian hares (Moreno Montanez et al, 1979;Martinez-Gomez et al, 1987;Blasco et al, 1996;Molina i Figueras, 1998). Many studies have been conducted on the helminth fauna of L. europaeus in other countries outside of the Iberian Peninsula, and there have been no reports of N. zembrae from this species (Sharpilo, 1975;Kutzer and Frey, 1976;Sugar et al, 1978;Forstner and Ilg, 1982;Soveri and Valtonen, 1983;Boag, 1987;Canestri-Trotti et al, 1988;Allgoewer, 1992;Poglayen et al, 1994;Molina i Figueras, 1998;Shimalov and Shimalov, 2001).…”
