New Additions to the Mammal List Documented in the Portuguese Red Data Book
Mathias, Marua da Luz; Mira, António; Joaquim, Tapisso; Pita, Ricardo; Neves, Tomé; Cabral, João Alexandre; Barros, Paulo; Rainho, AnaThis study outlines the procedures used for collecting, processing, and categorizing data on 16 new mammal species for mainland Portugal, belonging to four taxonomic groups: Eulipotyphla (1), Chiroptera (4), Rodentia (2), and Cetacea (9). Data collection and processing encompassed field and lab work and bibliographic compilation. Data categorization involves, whenever possible, the assessment of the approximate...
Patch spatial attributes and time to disturbance affect the emergence of source...
Crispim-Mendes, Tiago; Roos, Deon; Ferreira, Clara; Paupério, Joana; Silva, João Paulo; Godinho, Sérgio; Alves, Paulo Célio; Mira, António; Beja, PedroUnderstanding the demography of local populations within ephemeral habitat patches is crucial for effective local (site-based) conservation management in spatially and temporally heterogeneous environments. Evidence suggests that species persisting in networks of ephemeral patches often exhibit source-sink dynamics, where certain local populations act as temporary sources at some time between initial colonizati...

Relatedness reveals a strong road effect on female bat genetic connectivity
Medinas, Denis; Ribeiro, Vera; Barbosa, Soraia; Valerio, Francesco; Marques, João Tiago; Rebelo, Hugo; Paupério, Joana; Santos, Sara MariaThe effective management of species with small and fragmented populations requires an in-depth understanding of how the effects of human-induced habitat disturbance shape the structure and gene flow at fine spatial scales. Identification of putative environmental barriers that affect individual exchange among subpopulations is imperative to prevent extinction risks. Here, we investigated how landscape affects t...
Microtus lusitanicus rato-toupeira
Cerveira, Ana; Santos, Sara Maria; Paupério, JoanaEspécie de hábitos fossadores. Ocupa diversos habitats, desde prados ou pastagens com elevada cobertura herbácea, áreas agrícolas (pomares, olivais, outras culturas), bermas ou sebes,até habitats semi-urbanos (relvados de jardins; Santos et al. 2010b, 2011). Prefere áreas com solos macios e húmidos, onde constrói galerias subterrâneas (Mira & Mathias 2007, Santos et al. 2011). Pode ser encontrada desde o nível ...
Detection and Molecular Characterization of Giardia and Cryptosporidium spp. Ci...
Lux, Laura; Ulrich, Rainer G; Santos-Silva, Sérgio; Queirós, João; Imholt, Christian; Klotz, Christian; Paupério, Joana; Pita, RicardoCryptosporidium spp. and Giardia spp. are important diarrhea-causing protozoan parasites worldwide that exhibit broad host ranges. Wild small mammals can harbor host-adapted and potentially zoonotic species of both parasites. The aim of this study was to investigate Cryptosporidium spp. and Giardia spp. in wild rodents and shrews in Portugal, focusing on the protist’s occurrence and genetic diversity. Molecular...

From species detection to population size indexing: The use of sign surveys for...
Peralta, Dinora; Vaz Freire, Teresa; Ferreira, Clara; Mendes, Tiago; Mira, António; Santos, Sara; Alves, Paulo Célio; Lambim, Xavier; Beja, PedroMonitoring the occupancy and abundance of wildlife populations is key to evaluate their conservation status and trends. However, estimating these parameters often involves time and resource-intensive techniques, which are logistically challeng- ing or even unfeasible for rare and elusive species that occur patchily and in small numbers. Hence, surveys based on field identification of signs (e.g. faeces, footpri...
Landscape Characteristics Affecting Small Mammal Occurrence in Heterogeneous Ol...
Barão, Isabel; Queirós, João; Vale-Gonçalves, Hélia; Paupério, Joana; Pita, RicardoUnderstanding how small mammals (SM) are associated with environmental characteristics in olive groves is important to identify potential threats to agriculture and assess the overall conservation value and functioning of agro-ecosystems. Here, we provide first insights on this topic applied to traditional olive groves in northeast (NE) Portugal by assessing the landscape attributes that determine SM occurrence...
