Brown bear habitat use patterns across 19 years of population expansion in the ...
Nogueira, Carolina; Hipólito, Dário; Pando, Doriana; Carvalho, João; Fonseca, Carlos; Hartasánchez, Alfonso; Magadan, José Ramón; Rosalino, Luís MiguelContext Large carnivores have faced severe extinction pressures throughout Europe during the last centuries, where human-induced disturbances reached unprecedented levels. In the late twentieth century, the Cantabrian brown bear population was on the verge of extinction, due to poaching. Yet, the end of the last century was a turning point for this population. Presence data on the western Cantabrian subpopulati...
Friend or foe, what do the locals say? Attitudes towards the endangered Iberian...
Valente, Ana M.; Martins, Raquel; Figueiredo, Ana M.; Rosalino, Luís Miguel; Fonseca, Carlos; Torres, Rita T.The endangered Iberian wolf (Canis lupus signatus) populations have been decreasing in Portugal due to a combination of factors such as habitat destruction and human persecution. This is particularly worrying in Central Portugal, where packs are highly fragmented, isolated, and with few individuals. Human-Wildlife-Conflicts occur in this area due to high levels of livestock depredation, an outcome of the low di...
Dog in sheep’s clothing: livestock depredation by free-ranging dogs may pose ne...
Lino, Sofia; Rossa, Mariana; Fernandes, Joana M.; Barros, Tânia; Lino, Ana; Hipólito, Dário; Ferreira, Eduardo; Aliácar, Sara C.; Cadete, DuarteLivestock depredation is a common cause of human-carnivore conflicts. In Portugal, free-ranging dogs are increasingly abundant and overlap endangered Iberian wolf territories, with reports of livestock depredation. However, the lack of awareness about dogs’ possible role as predators leads to bias against wolves in cases of damages. Our goal was to assess and compare wolf and free-ranging dog’s diet composition...
MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...
Grilo, Clara; Afonso, Beatriz C.; Afonso, Filipe; Alexandre, Marta; Aliácar, Sara; Almeida, Ana; Alonso, Ivan Prego; Álvares, Francisco; Alves, PauloMammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...
Antimicrobial resistance in commensal Staphylococcus aureus from wild ungulates...
Ramos, Beatriz; Rosalino, L. M.; Palmeira, Josman D.; Torres, Rita T.; Cunha, Mónica V.Staphylococcus aureus is a human pathobiont (i.e., a commensal microorganism that is potentially pathogenic under certain conditions), a nosocomial pathogen and a leading cause of morbidity and mortality in humans. S. aureus is also a commensal and pathogen of companion animals and livestock. The dissemination of antimicrobial resistant (AMR) S. aureus, particularly methicillin-resistant (MRSA), has been associ...

Parasites of the reintroduced Iberian Lynx (Lynx pardinus) and Sympatric Mesoca...
Figueiredo, Ana M.; Madeira de Carvalho, Luís; González, María J. P.; Torres, Rita T.; Pla, Samuel; Núñez-Arjona, Juan C.; Rueda, CarmenABSTRACT - The Iberian lynx (Lynx pardinus) is one of the most endangered felid species in the world. Conservation efforts have increased its population size and distribution and reinforced their genetic diversity through captive breeding and reintroduction programmes. Among several threats that the Iberian lynx faces, infectious and parasitic diseases have underlined effects on the health of their newly reintr...
Emergence and Spread of Cephalosporinases in Wildlife: A Review
Palmeira, Josman D.; V. Cunha, Mónica; Carvalho, João; Ferreira, Helena; Fonseca, Carlos; Torres, Rita T.In the last decade, detection of antibiotic resistant bacteria from wildlife has received increasing interest, due to the potential risk posed by those bacteria to wild animals, livestock or humans at the interface with wildlife, and due to the ensuing contamination of the environment. According toWorld Health Organization, cephalosporins are critically important antibiotics to human health. However, acquired r...
Assessment of antibiotic resistance of Escherichia coli isolates and screening ...
Dias, Diana; Torres, Rita T.; Kronvall, Göran; Fonseca, Carlos; Mendo, Sónia; Caetano, TâniaAntibiotic resistance is an emerging global problem. Wild animals are rarely exposed to antibiotics and therefore low levels of antibiotic resistance are expected. However, the growing interactions of these animals with humans and livestock may have a huge impact on their bacterial flora. This study aimed to assess the levels of antibiotic resistance in Escherichia coli isolated from widespread wild ungulates i...
