Drivers of survival in a small mammal of conservation concern: an assessment us...
Proença-Ferreira, António; Ferreira, Clara; Leitão, Isabel; Sabino-Marques, Helena; Barbosa, Soraia; Encarnação, Cláudia; Alpizar-Jara, RussellAlthough important to guide conservation management, detailed demographic studies on rare or elusive species inhabiting fragmented, human-dominated landscapes are often hampered by the species' low densities, and the logistic and ethical constraints in obtaining reliable information covering large areas. Genetic non-invasive sampling (gNIS) provides cost-effective access to demographic information, though its a...
Genetic non-invasive sampling (gNIS) as a cost-effective tool for monitoring el...
Ferreira, Clara; Sabino-Marques, Helena; Barbosa, Soraia; Costa, Pedro; Encarnação, Cláudia; Alpizar-Jara, Russell; Pita, Ricardo; Beja, PedroGenetic non-invasive sampling (gNIS) may provide valuable information for population monitoring, as it allows inferences of population density and key behavioural traits such as dispersal, kinship and reproduction. Despite its enormous potential, gNIS has rarely been applied to small mammals, for which live-trapping is still the most commonly used sampling method. Here we evaluated the applicability and cost-ef...
Combining genetic non-invasive sampling with spatially explicit capture-recaptu...
Sabino-Marques, Helena; Ferreira, Clara; Paupério, Joana; Costa, Pedro; Barbosa, Soraia; Encarnação, Cláudia; Alpizar- Jara, Russel; Alves, Paulo CélioEstimating the size of animal populations is essential for understanding the demography and conservation status of species. Genetic Non-Invasive Sampling (gNIS) combined with Spatially Explicit Capture-Recapture (SECR) modelling may provide a practical tool to obtain such estimates. Here, we evaluate for the first time the potential and limitations of this approach to estimate population densities for small mam...
Endemic species may have complex histories: within refugium phylogeography of a...
Barbosa, Soraia; Paupério, Joana; Herman, J.S.; Ferreira, C.M.; Pita, Ricardo; Vale, H.M.; Cabral, João; Garrido-Garcia, Antonio; Soriguer, RamonGlacial refugia protected and promoted biodiversity during the Pleistocene, not only at a broader scale, but also for many endemics that contracted and expanded their ranges within refugial areas. Understanding the evolutionary history of refugial endemics is especially important in the case of endangered species to recognize the origins of their genetic structure and thus produce better informed conservation p...
