Among-individual variation in white seabream (Diplodus sargus) spatial behaviou...
De Benito Abelló, Carmela; Bentes, Luis; Sousa, Inês; Pedaccini, Marie; Villegas-Ríos, David; Olsen, Esben Moland; Gonçalves, Jorge Manuel SantosMarine protected areas (MPAs), and specially no-take areas (NTAs), play an important role in protecting target populations from fisheries. When developing spatial conservation and management tools, the design has mainly focused on population-level measures of fish home ranges, spawning and feeding areas, and migration routes. Intraspecific differences in fish behaviour, however, are often not accounted for, eve...
Historical gene flow constraints in a northeastern atlantic fish: Phylogeograph...
Almada, Frederico José Oliveira de; Francisco, Sara Martins; Lima, Cristina Silva; Fitzgerald, Richard; Mirimin, Luca; Villegas-Ríos, DavidMaterial suplementar, disponível online em: https://dx.doi.org/10.6084/m9.figshare.c.3683176.; The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biological and ecological fa...
On the absence of genetic differentiation between morphotypes of the ballan wra...
Almada, Frederico José Oliveira de; Casas, Laura; Francisco, Sara Martins; Villegas-Ríos, David; Saborido-Rey, Fran; Irigoien, XabierThe ballan wrasse, Labrus bergylta (Labridae), is a protogynous hermaphrodite fish common in the north-eastern Atlantic from Norway to Morocco. It is a commercially important resource for local fisheries and is currently being used as cleaner fish to control sea lice in salmon farms in northern Europe. Two distinct colour patterns have been recently reported in the literature: plain and spotted. These individua...
Ichthyofauna of the Selvagens Islands. Do small coastal areas show high species...
Almada, Frederico; Abecasis, David; Villegas-Ríos, David; Henriques, Sofia; Pais, Miguel Pessanha; Batista, Marisa Isabel; Costa, Bárbara Horta eThe Selvagens Islands are located in the northeastern Atlantic between the Canary Islands and Madeira Island. As a result of their small size, remote location and harsh sea conditions only a few studies have been conducted to describe their marine species diversity. We were able to identify 29 new coastal fish species, an increase of 33% in the ichthyofauna described for these islands (n = 88). There is a preva...

Early development stages of the red blenny, Parablennius ruber (Teleostei: Blen...
Villegas-Ríos, David; Martínez, Alejandro; Palmero, Ana M.; Azevedo, José M. N.Little is known about the early development stages of Parablennius ruber. In this paper the following stages are described, and illustrations provided for the first time: middle stage egg, late stage egg, yolk-sac larva and preflexion larva. Recently laid eggs were spherical and orange, attached to the substratum in rock crevices. Eggs measured 1.02 mm in diameter. Newly hatched larva measured 4.65 mm total len...
