Diet of non-native pikeperch Sander lucioperca (Linnaeus, 1758) in Portugal: a ...
Ribeiro, D.R.; Gago, João; Gkenas, C.; Ferreira, M.; Gabriel, S.; Ribeiro, F.The introduction rate of new species is expanding worldwide, being a major driver of biodiversity loss and biotic homogenisation (Strayer & Dudgeon 2010). Such phenomenon is particularly serious in Mediterranean regions (Anastácio et al. 2019) with the modification of habitats (construction of dams and barriers) associated with the establishment of non-native fish (hereafter NNF) (Radinger et al. 2019). The spr...
Downwearing rates on shore platforms of different calcareous lithotypes
Moura, D.; Gabriel, S.; Ramos-Pereira, A.; Neves, M.; Trindade, J.; Viegas, J.; Veiga-Pires, C.; Ferreira, Ó.; Matias, A.; Jacob, J.; Boski, T.Vertical lowering (downwearing) of shore platform surfaces is a very important mechanism in their morphological evolution albeit much remains incompletely understood. The efficacy of mechanical and chemical weathering acting on a given substrate, together with erosional processes, influences downwearing rates. In order to determine the relationship between lithotypes and downwearing rates, data collected from a...

Haematology, genotoxicity, enzymatic activity and histopathology as biomarkers ...
Sánchez-Chardia, Alejandro; Marques, Carla; Gabriel, S.; Capela e Silva, Fernando; Cabrita, António; López-Fuster, M.J.; Nadal, J.Haematological (WBC, RBC, Hgb and Hct) and genotoxicity (MNT) parameters, hepatic enzymatic activities (GST, GPx and GR), and a histopathological evaluation of liver, kidneys and gonads were assessed as general biomarkers of metal pollution in the shrew Crocidura russula inhabiting a pyrite mining area. Specimens exposed to metals presented a few significant alterations when compared with reference animals: GST...
