Several specimens of Pachydactylus angolensis, a poorly known Angolan endemic gecko, have recently been collected in southern Angola, considerably increasing its known distribution range. Previous observations led to the hypothesis that two different morphological forms exist in the country—a coastal form and an inland form. Leer más.
Histological examinations showed intense involvement of the superficial layers of the epidermis and qPCR analyses yielded infection loads greater than 100 000 genomic equivalents of zoospores. These results suggest that this introduced species could behave as a Bd ‘supershedder’, and recommend to control its expansion due to its important role in the dynamic of chytridiomycosis. Leer más.
emarkable range increases occur for the subspecies V. monticola atlanticaand V. monti-cola monticola, the latter confirmed by genetic assessment, as well as for V. monticola saintgironsi with a new record in Jbel Bou Naceur. We note the occurrence of habitat degradation across the species range, likely promoted by anthropogenic factors as deforestation, aridification and ove rgrazing. Leer más.
Studies of the effects of insularity on animal signals are scarce, particularly in lizards. Here, we use Lilford’s wall lizard from Dragonera (Podarcis lilfordi gigliolii) to ask how island conditions have affected its repertoire of social signals, focusing on two visual signals shared by many Podarcis species: ultraviolet (UV)–blue-reflecting ventrolateral colour patches and visual displays.

Our findings highlight the importance of conservation programmes focused on preserving the functional diversity of life history strategies jointly with the phylogenetic representativity of these highly threatened groups. Leer más.
