Influence of landscape heterogeneity and meteorological features on small mamma...
Marques, Sara F.; Rocha, Rita G.; Mendes, Eduardo S.; Fonseca, Carlos; Ferreira, Joaquim P.The abundance and distribution of small mammals are important factors for ecosystem structure and functioning, often affected by spatial heterogeneity and seasonal fluctuations. In this study, we tested the influence of habitat type, landscape composition and meteorological conditions on small mammal abundance and richness in the heterogeneous coastal wetland landscape of Baixo Vouga Lagunar (BVL), NW Portugal....
Three mammal species distinction through the analysis of scats chemical composi...
Saraiva, Maria J.; Salvador, Ângelo C.; Fernandes, Tony; Ferreira, Joaquim P.; Barros, António S.; Rocha, Sílvia M.; Fonseca, CarlosIn the last years, new approaches use scats analysis in ecological studies, like gas chromatographic techniques, has been developed. The aim of this study is to use VOCs (volatile organic compounds) released from scats to distinguish three mammal species: the ungulates red and fallow deer and the carnivore Eurasian otter through the application of SPME/GC??GC-ToFMS. This chromatographic technique has never been...
Effectiveness of habitat management in the recovery of low-density populations ...
Godinho, Sérgio; Mestre, Frederico; Ferreira, Joaquim P.; Machado, Rui; Santos, PedroUnderstanding the relationship between spatial pat- terns of landscape attributes and population presence and abundance is essential for understanding population processes as well as supporting management and conservation strate- gies. This study evaluates the influence of three factors: envi- ronment, habitatmanagement, and season on the presence and abundance of the wild rabbit (Oryctolagus cuniculus), an imp...
Human-related factors regulate the spatial ecology of domestic cats in sensitiv...
Ferreira, Joaquim P.; Leitão, Inês; Santos-Reis, Margarida; Revilla, EloyBackground: Domestic cats ranging freely in natural areas are a conservation concern due to competition, predation, disease transmission or hybridization with wildcats. In order to improve our ability to design effective control policies, we investigate the factors affecting their numbers and space use in natural areas of continental Europe.
