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...

Disrupted dispersal and its genetic consequences: Comparing protected and threa...
Silva, Maria Joana Ferreira da; Kopp, Gisela H.; Casanova, Catarina; Godinho, Raquel; Minhós, Tânia; Sá, Rui; Zinner, Dietmar; Bruford, Michael W.Dispersal is a demographic process that can potentially counterbalance the negative impacts of anthropogenic habitat fragmentation. However, mechanisms of dispersal may become modified in populations living in human-dominated habitats. Here, we investigated dispersal in Guinea baboons (Papio papio) in areas with contrasting levels of anthropogenic fragmentation, as a case study. Using molecular data, we compare...

Reassortment among picobirnaviruses found in wolves
Conceição-Neto, Nádia; Mesquita, João R; Zeller, Mark; Yinda, Claude Kwe; Álvares, Francisco; Roque, Sara; Petrucci-Fonseca, Francisco; Godinho, RaquelWe conducted a viral metagenomics study in diarrheic free-ranging wolves in Portugal, revealing for the first time the presence of reassortant picobirnaviruses. These viruses shared identical capsid segments together with diverse RNA-dependent RNA polymerase segments. Even though causality between these picobirnaviruses and diarrhea could not be established, the study nonetheless confirms for the first time tha...
Conservation Biogeography of the Sahara‐Sahel: additional protected areas are n...
Brito, José C.; Tarroso, Pedro; Vale, Cândida G.; Martínez‐Freiría, Fernando; Boratyński, Zbyszek; Campos, João C.; Ferreira, Sónia; Godinho, RaquelAim Identification of priority conservation areas and evaluation of coverage of the current protected areas are urgently needed to halt the biodiversity loss. Identifying regions combining similar environmental traits (climate regions) and species assemblages (biogroups) is needed for conserving the biodiversity patterns and processes. We identify climate regions and biogroups and map species diversity across t...
Extensive intraspecific polymorphism detected by SSCP at the nuclear C-mos gene...
Godinho, Raquel; Domingues, Vera dos Santos; Crespo, Eduardo G.; Ferrand, NunoC-mos is a highly conserved intronless gene that has proved useful in the analysis of ancient phylogenetic relationships within vertebrates. We selected the Iberian endemic Schreiber’s green lizard (Lacerta schreiberi) that persisted in allopatric refugia since the late Pliocene to investigate the utility of the Cmos nuclear gene for intraspecific phylogeographic studies. Our combination of DNA sequencing with ...
Agonistic behaviour and sound production in Gaidropsarus mediterraneus, (Gadidae)
Almada, Vítor Carvalho; Amorim, Maria Clara Pessoa; Pereira, Eduarda; Almada, Frederico José Oliveira de; Matos, Ricardo Jorge S.C.; Godinho, RaquelAgonistic behaviour and sound production were described for captive Gaidropsarus mediterraneus, a shore-dwelling gadoid. Thump-like sounds were produced during agonistic interactions, which involved disputes over access to shelter sites.
