Silva, Clara; Lourenço, Rui; Godinho, Sérgio; Gomes, Edgar; Sabino-Marques, Helena; Medinas, Denis; Neves, Vânia; Silva, Carmo; Rabaça, JoãoThe increasing road networks threaten ecosystems by direct effects such as increased mortality due to collision with vehicles and by various indirect effects leading to road avoidance. We censused Tawny Owls Strix aluco and Little Owls Athene noctua in 2005, 2007 and 2009 in a rural landscape in Southern Portugal in order to study the effects of roads and habitat characteristics on Tawny Owl density and Little...
