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...

Desenhando a mobilidade. A potencialidade do sketching nos estudos de mobilidade
Costa, Rosalina; Sales Oliveira, Catarina; Barbosa, A. MárciaEste artigo debruça-se sobre as potencialidades do sketching nos estudos de mobilidade. Começando por cruzar as preocupações e especificidades das metodologias móveis com as questões levantadas pelo uso das metodologias baseadas na arte em ciências sociais e em particular na sociologia, confronta-se este enquadramento teórico metodológico com a experiência de um workshop de metodologias móveis organizado no con...
Distribution of alien tetrapods in the Iberian Peninsula
Ascensão, Fernando; D'Amico, Marcello; Martins, Ricardo C.; Rebelo, Rui; Barbosa, A. Márcia; Bencatel, Joana; Barrientos, Rafael; Abellán, PedroWe present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and managemen...

Changes in potential mammal diversity in national parks and their implications ...
Estrada, Alba; Barbosa, A. Márcia; Real, RaimundoObserved species richness (OSR) is a widely used and well-studied biodiversity metric. However, non-observed species in favorable ecosystems are also relevant. Two metrics that include observed and potential species were recently defined: potential biodiversity (hereafter potential species richness—PSR) and geometric mean of favorabilities (GMF). We used these metrics to evaluate the national park network of ma...
Research trends and geographical distribution of mammalian carnivores in Portug...
Bencatel, Joana; Ferreira, Catarina C.; Barbosa, A. Márcia; Rosalino, Luís Miguel; Álvares, FranciscoInformation regarding species’ status at a regional scale is instrumental for effective conservation planning. Some regions of southwestern Europe, such as Portugal, albeit included in the Mediterranean biodiversity hotspot, lack a detailed assessment of the distribution patterns of several taxonomic groups, such as carnivores. Moreover, information is scattered, often unreliable and biased towards some species...
gDefrag: Graph-Based Landscape De-Fragmentation
Mestre, Frederico; Ascensão, Fernando; Barbosa, A. MárciaThis package provides a set of tools to help the ecological de-fragmentation of landscapes divided by linear transportation infrastructures. It works by prioritizing the different sections of these infrastructures (e.g. roads, railways) to increase the available amount of a given resource for widlife.
Complementing the Pleistocene biogeography of European amphibians: Testimony fr...
Sánchez-Montes, Gregorio; Recuero, Ernesto; Barbosa, A. Márcia; Martínez-Solano, IñigoTo reconstruct the historical biogeography of Hyla molleri, a tree frog endemic to the Eurosiberian and Mediterranean bioclimatic zones in the Iberian Peninsula. Location: Iberian Peninsula
