Estudo das populações de pequenos mamíferos através da análise de egagrópilas d...
Bettencourt, Sofia; Vale-Gonçalves, Hélia; Ferreira, Rafael; Carrola, João SoaresThe study of small mammal populations can be carried out through direct methods involving their capture through traps, and indirect non-invasive methods such as camera trapping, prospecting and collection of signs of presence and analysis of barn owl's regurgitated pellets. The barn owl (Tyto alba) is a nocturnal bird of prey with a global distribution, with the exception of the Arctic regions. This species fee...

Detection and Molecular Characterization of Giardia and Cryptosporidium spp. Ci...
Lux, Laura; Ulrich, Rainer G; Santos-Silva, Sérgio; Queirós, João; Imholt, Christian; Klotz, Christian; Paupério, Joana; Pita, RicardoCryptosporidium spp. and Giardia spp. are important diarrhea-causing protozoan parasites worldwide that exhibit broad host ranges. Wild small mammals can harbor host-adapted and potentially zoonotic species of both parasites. The aim of this study was to investigate Cryptosporidium spp. and Giardia spp. in wild rodents and shrews in Portugal, focusing on the protist’s occurrence and genetic diversity. Molecular...
Landscape Characteristics Affecting Small Mammal Occurrence in Heterogeneous Ol...
Barão, Isabel; Queirós, João; Vale-Gonçalves, Hélia; Paupério, Joana; Pita, RicardoUnderstanding how small mammals (SM) are associated with environmental characteristics in olive groves is important to identify potential threats to agriculture and assess the overall conservation value and functioning of agro-ecosystems. Here, we provide first insights on this topic applied to traditional olive groves in northeast (NE) Portugal by assessing the landscape attributes that determine SM occurrence...

First Detection of Borrelia burgdorferi sensu lato DNA in Serum of the Wild Boa...
Faria, Ana Sofia; Paiva-Cardoso, Maria das Neves; Nunes, Mónica; Carreira, Teresa; Vale-Gonçalves, Hélia; Veloso, Octávia; Coelho, CatarinaLyme borreliosis is the most common tick-borne zoonosis in the northern hemisphere. Several vertebrates are crucial in the epidemiological cycle of Borrelia burgdorferi sensu lato, but the role of wild boar as a reservoir is still unknown. Sera were collected from 90 wild boars shot in the Trás-os-Montes region, Northern Portugal (hunting season 2011/2012). In this study, Borrelia DNA was detected for the first...
he contribution of the Barn Owl (Tyto alba) feeding ecology to confirm bat spec...
Vale-Gonçalves, Hélia; Barros, Paulo Alexandre Rodrigues de; Braz, Luís; Cabral, JoãoThe Barn owl (Tyto alba) is an opportunistic species which feeds mainly on small mammals but also on birds, bats, reptiles, amphibians, insects and fishes. With regard to bats, several studies in Europe suggest that this group constitutes a small portion of the Barn owl diet representing less than 1% of its prey items. Through the analysis of 2,934 Barn owl pellets, collected between 2006 and 2014 in 27 sites/n...
Prevalence of Leptospira antibodies in wild boars (Sus scrofa) from Northern Po...
Vale-Gonçalves, Hélia; Faria, M. C.; Nunes-Pereira, M.; Faria, A. S.; Vieira, M. L.; Cabral, João; Paiva-Cardoso, Maria das NevesLeptospirosis is a zoonosis of worldwide distribution, caused by infection with pathogenic spirochetes of the genus Leptospira. The wild boar (Sus scrofa), an important hunting species in Europe, seems to play a significant role in the epidemiological cycle of leptospirosis. A total of 101 serum samples from wild boar hunted in Northern Portugal were analysed for leptospiral antibodies detection by microscopic ...
New records on the distribution of three rodent species in NE Portugal from bar...
Vale-Gonçalves, Hélia; Cabral, JoãoIn Portugal some information has been published about the spatial distribution, at a local or regional scale, for several small mammal species (e.g. Madureira & Magalhães 1980, Magalhães & Madureira 1980, Tomé 1994, Cruz et al. 2002, Roque 2003, Temme 2003, Vale-Gonçalves 2006, Godinho 2007, Mira et al. 2008, Santos et al. 2009, Rosalino et al. 2010, Machado 2011, Paupério 2012, Garrido-García et al. 2013).
