- Portuguese purse seine fishery spatial and resource overlap with top predatorsPublication . Wise, Laura; Galego, Catarina; Katara, Isidora; Marçalo, Ana; Meirinho, Ana; Monteiro, Silvia S.; Oliveira, Nuno; Santos, Jorge; Rodrigues, Pedro; Araujo, Helder; Vingada, Jose; Silva, AlexandraThe Portuguese purse seine fishery, with average annual catches of 70 000 tonnes, operates mainly in coastal areas and targets small pelagic fish (SPF). Potential competition for resources may occur between the fishery and some species of marine mammals and seabirds, as suggested by observed incidental catches. For those species directly affected by the fishery, the spatial distribution of marine taxa and the fishing fleet are key pieces of information for spatial planning and management. We analysed the spatial and resource overlap between the fishery's distribution and effort, and the distribution and abundance of 6 species of top predators -seabirds (n = 4) and marine mammals (n = 2) between 2010 and 2014. Estimates of annual consumption by top predators and the fishery catch within the distributional range of one of their main prey species (sardine Sardina pilchardus) were also determined. Spatial overlap between all considered species and the fishery was low (<0.221), and only 2 species (common dolphins Delphinus delphis and Cory's shearwaters Calonectris borealis) showed high resource overlap with the fishery (>0.7). Overall, values of consumption of SPF by the top predators were of the same order of magnitude as mean annual purse seine landings for the studied area. Our results can be used for marine spatial planning, including designation of Marine Protected Areas and the development of an ecosystem-based model for the effective management of the Portuguese purse seine fishery that takes into account the consumption of natural predators.
- Student diversity and student voice conceptualisations in five European countries: Implications for including all students in schoolsPublication . Messiou, Kyriaki; Bui, Lien Thien; Ainscow, Mel; Gasteiger-Klicpera, Barbara; Bešić, Edvina; Paleczek, Lisa; Hedegaard-Sørensen, Lotte; Ulvseth, Hilde; Vitorino, Teresa; Santos, Jorge; Simon, Cecilia; Sandoval, Marta; Echeita, GerardoThis article analyses the ways in which notions of student diversity and student voice are defined in five European countries, two terms directly related to notions of inclusion. In so doing, it examines links between the two terms, noting that, often, they are used in international research without acknowledging the ways that they are defined within particular national contexts. Using literature and policy documents from five countries (i.e. Austria, Denmark, England, Portugal and Spain), the article highlights similarities as well as differences in the various contexts. Through the analysis of these texts, the paper concludes that diversity is conceptualised in five ways, although there is occasionally overlap of different conceptualisations in some of the countries. Meanwhile, the term 'student voice' is a term that is not used in some of the countries' policies. Instead, other terms that relate to student voice, such as 'participation', are used. The paper discusses the implications of these varied understandings for the promotion of the inclusion of all students in schools.
