The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
The Effects of Multiple Predators on the Size Structure of Red Urchin Populations in British Columbia
The Effects Of Multiple Predators On the Size Structure of Red Urchin Populations in British Columbia An undergraduate Directed Studies (BISC 498) research project by Christine Stevenson Introduction Predator-prey body size relationships influence trophic structure, transfer efficiency, and interaction strength within a food web (Jonsson and Ebenman 1998). Size distributions of both predators and prey are an important component to the population dynamics of a community. Knowledge of the strength of predatory interactions within a food web can provide insight to the relationships between the sizes of prey and their predators. Predators are generally larger than the size their prey and predator size is often positively correlated to prey size (Vezina 1985, Warren and Lawton 1987, Cohen et al. 1993). The relative body size of a predator and its prey largely contribute to the ecology and evolutionary consequences of predator-prey relationships. This is most defined in systems involving size- dependent predators. These predators are effective agents of selection among prey species that differ in body size or growth rate. Size dependent predators therefore influence the structure of prey populations by diminishing prey species of a preferred size (Kerfoot and Peterson 1980). Prey species that can reach a large size through embellishments of the exoskeleton can often attain a size refuge from predators (Sousa 1992). Thus, the risk of predation may be lower for larger prey compared to smaller individuals. The risk of an individual prey being consumed may also depend on the size- structure of the predator population, as larger predators generally have the ability to handle and consume larger prey (Sousa 1992). -

A Estratégia Nacional para o Mar 2013-2020 (ENM 2013) enuncia a criação de novas AMPs como um objetivo estratégico. Paralelamente, a Estratégia Europeia para o Crescimento Azul (EC 2012) salienta a necessidade de integrar os serviços de ecossistema, e os seus valores, de forma a garantir uma gestão sustentável e eficiente das atividades que têm lugar no oceano. As AMPs, como ferramentas de gestão espacial dedicadas à conservação dos ecossistemas marinhos, são essenciais para implementar estas estratégias e assegurar diferentes necessidades sociais, garantindo a conservação dos ecossistemas costeiros e marinhos, e os seus serviços para as gerações vindouras. O projeto AMPICvalue assenta nestas premissas e apresenta uma avaliação do impacto económico direto (IED) e mapeamento das principais atividades suportadas por um dos maiores recifes costeiros de Portugal. -
Sibling Bald Sea Urchin Disease Affecting the Edible [I
Sibling Bald Sea Urchin Disease affecting the edible Paracentrotus lividus (Echinodermata: Echinoidea) in Sardinia (Italy) Grech, D., Guala, I., Farina, S. IMC - International Marine Centre - Loc. Sa Mardini, Torregrande, 09170 Oristano, Italy Corresponding Author: Daniele Grech Email address: [email protected] Different species of echinoids and bivalves are suffering infectious diseases as the effect of ocean warming. In Sardinia (Western Mediterranean Sea) the keystone sea urchin species Paracentrotus lividus (Lamarck 1816) is widely appreciated as edible resource. Recently, a number of individuals were found to be infected by a no specified bacterial morphologically matching to a “bald sea urchin disease” (Fig. 1). In February 2019, a sampling campaign took place in two locations in the West and East Coast, inside and in proximity of local Marine Protected Areas. Field samplings were approved by the Regione Autonoma Sardegna (Fishing License for scientific purposes n.310/AP SCIE/N.1 10/01/2019). Samplings were carried out at the end of February 2019, when water temperature was 13°C. For each sampled site we performed two replicates of fast 50 m belt transects to estimate the infection rate as the total individuals infected on the total counted. The estimated infection rate was around 5% in both of sampled locations. A higher level of preyed sea urchins was observed, compared to natural predatory level previously observed in all the surveyed sites. Moreover, an unusual amount of dead sea urchins has been observed stranded on the storm berm, neighbouring one of the sampled sites. Microbiological analysis puts in evidence bacterial infection as the potential causal agent that could be temperature-related. -
Vulnerable Forests of the Pink Sea Fan Eunicella Verrucosa in the Mediterranean Sea

Despite the recognized importance of these habitats, they have been scantly studied and their distribution is mostly unknown. This study reports the new finding of E. verrucosa forests in the Mediterranean Sea, and the updated distribution of this species that has been considered rare in the basin. In particular, one site off Sanremo (Ligurian Sea) was characterized by a monospecific population of E. verrucosa with 2.3 0.2 colonies m 2. By combining ± − new records, literature, and citizen science data, the species is believed to be widespread in the basin with few or isolated colonies, and 19 E. verrucosa forests were identified. The overall associated community showed how these coral forests are essential for species of conservation interest, as well as for species of high commercial value. For this reason, proper protection and management strategies are necessary. Keywords: Anthozoa; Alcyonacea; gorgonian; coral habitat; coral forest; VME; biodiversity; mesophotic; citizen science; distribution 1. Introduction Arborescent corals such as antipatharians and alcyonaceans can form mono- or multispecific animal forests that represent vulnerable marine ecosystems of great ecological importance [1–4]. -

Genetic and morphological divergence and phylogenetic relationships of Scorpaeniformes fishincludingtwogeneraandsixspecies, Helicolenus dactylopterus, Scorpaena maderensis, Scorpaena porcus, Scorpaena elongata, Scorpaena scrofa, Scorpaena notata, living in the Mediterranean Sea, were investigated with morphological and mitochondrial 16S rDNA sequence data. The mean nucleotide diversity was found to be 0.0792. Average sequence divergence between species of Sebastidae and Scorpaenidae was 8.4%, and 6.4%. between species of the genus Scorpaena. For congeneric comparisions, the lowest genetic divergence (0.7%) was observed between S. porcus and S. notata, and the highest divergence (10.8%) was detected between S. maderensis and S. notata. High levels of nucleotide divergence were detected between species of two families, and the maximum value was found to be 14.5% between H. dactylopterus and S. elongata. The two phylogenetic methods (NJ and MP)identifiedtwomajorlineages. IntheNJtree S. elongata wasthesistergroupto S. scrofa. S. maderensis was more divergent from these groups. Another lineage contained S. porcus and S. notata. The topology of the MP tree is similar to that of the NJ tree. The pattern and degree of morphological differentiation was not congruent with the genetic differentiation. The Euclidiean distances of morphological data revealed very high morphological divergence between the two families. -
