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...

A metabarcoding tool to detect predation of the honeybee Apis mellifera and oth...
Verdasca, Maria João; Godinho, Raquel; Rocha, Rita Gomes; Portocarrero, Marco; Gigante Carvalheiro, Luísa; Sampaio e rebelo, Rui; Rebelo, HugoThe invasive Vespa velutina has been widely referred as an effective predator of honeybees. Despite the potential risk to pollination services provision and honey production, there is no accurate quantification and assessment of its real consequences for honeybees. To date, the identification of the honeybee and other insects in the diet of V. velutina has been investigated by direct observation of adult foragi...

The Araguaia River as an Important Biogeographical Divide for Didelphid Marsupi...
Rocha, Rita Gomes; Ferreira, Eduardo; Loss, Ana Carolina; Heller, Rasmus; Fonseca, Carlos; Costa, Leonora PiresThe riverine barrier model suggests that rivers play a significant role in separating widespread organisms into isolated populations. In this study, we used a comparative approach to investigate the phylogeography of 6 didelphid marsupial species in central Brazil. Specifically, we evaluate the role of the mid-Araguaia River in differentiating populations and estimate divergence time among lineages to assess th...
Seasonal flooding regime and ecological traits influence genetic structure of t...
Rocha, Rita Gomes; Ferreira, Eduardo; Fonseca, Carlos; Justino, Juliana; Leite, Yuri Luiz Reis; Costa, Leonora PiresAlthough codistributed species are affected by the same abiotic factors, such as rivers and seasonal flooding regimes, ecological traits, such as locomotion hab- its and habitat preferences, may also influence differences in levels of genetic diversity and differentiation. We examined population genetic structure and diversity of Hylaeamys megacephalus and Oecomys aff. roberti, two cricetid rodent species from ...
Seasonally flooded stepping stones: emerging diversity of small mammal assembla...
Rocha, Rita Gomes; Ferreira, Eduardo; Martins, Iracy Coelho Menezes; Costa, Leonora Pires; Fonseca, CarlosSeasonally flooded natural forest fragments, so-called ipucas, in the Araguaia alluvial plain of the state of Tocantins, central Brazil, represent a peculiar landscape that is poorly surveyed. This study considers the diversity in the small mammal assemblage and the zoogeographical patterns of this assemblage when compared to 30 other study sites in Brazil. Results: ‘Ipucas’ harbour species adapted to disturbed...
Will an ancient refuge become a modern one? A critical review on the conservati...
Rocha, Rita Gomes; Wauters, Lucas A.; Mathias, Maria da Luz; Fonseca, CarlosMediterranean peninsulas are well-known glacial refugia for several mammal species. For Eurasian red squirrel ( Sciurus vulgaris ), a forest-dwelling rodent, there is some evidence that population diversification was influenced by these refugia. Here, we review the poorly known history of the red squirrel in the Iberian Peninsula, and discuss current threats to this species, suggesting conservation guidelines a...
