Climate change may be a game-changer for scientific research by promoting a science that is grounded in linking the production of knowledge and societal action in a transition toward more sustainable development pathways. Here, we discuss participatory action-research (PAR) as a way of thinking and leading investigations that may promote incremental and transformative changes in the context of climate change adaptation research. Our exploration is addressed in the Portuguese context, where PAR and sustainable transition studies are still marginal, and adaptation processes are a recent topic on political agendas. We describe the characteristics of PAR and use two studies of adaptation to illustrate how research and practice co-evolve through interactive... |

The social and ecological systems of Mediterranean streams are intrinsically linked as a result of long human occupation. In this region, these links vary greatly across small distances due to geomorphology, resulting in great diversity across space, which poses particular challenges for understanding and managing these systems. This demands (i) interdisciplinary integration of knowledge that focuses on the social–ecological interactions, while according due consideration to the whole; and also (ii) transdisciplinary integration, integrating lay and expert knowledge to understand local specificities. To address these needs—a focus on interactions and local knowledge—the research presented here studies the... |

Diatom and coccolithophorid abundance and diatom assemblage composition found in the water column along the Portuguese margin, during upwelling and non-upwelling conditions, are compared to the distribution patterns observed in the recent sediments from the same area. The water column results indicate a one order of magnitude increase in phytoplankton biomass during upwelling conditions (summer), with diatoms being the most important contributors. Coccolithophorids, on the contrary, dominate the phytoplankton in winter (non-upwelling), The comparison of the upwelling and non-upwelling spatial distribution of these phytoplankton groups to their sedimentary record reveals the sediment record as a reflection of the upwelling situation, preserving most of its... |

Despite the economic importance of oysters due to the high aquaculture production of several species, the current knowledge of oyster phylogeny and systematics is still fragmentary. In Europe, Ostrea edulis, the European flat oyster, and Ostreola stentina, the Provence oyster or dwarf oyster, are both present along the European and African, Atlantic and Mediterranean, coasts. In order to document the relationship not only between O. stentina and O. edulis, but also with the other Ostrea and Ostreola species, we performed a sequence analysis of the 16S mitochondrial fragment (16S rDNA: the large subunit rRNA-coding gene) and the COI fragment (COI: cytochrome oxidase subunit I). Oysters were sampled from populations in Portugal (two populations), Tunisia... |

The MAST II WAVEMOD Project aimed at improving stochastic modelling of ocean waves and currents in coastal waters. In order to supplement existing data, two measurement campaigns were carried our, one on the Atlantic coast of Portugal, and, secondly, on the northern coast of Crete in the Mediterranean. The Portuguese measurements covered 7 months during winter 1993-1994, while off Crete, measurements started early in February 1994 and continued for 10 months, In both sites, two directional Waveriders and one non-directional Waverider were deployed along a transect our from the coast in water depths between 10 and 100 m. In addition, the Mediterranean site also incorporated measurements of mean current velocities. Available satellite data were analysed to... |

Marine landings in Portugal have decreased at a higher rate than fishing effort in the last 20 years. Identifying the variables driving the quantity and composition of landings is pivotal to understand the dynamics of the fisheries sector, which entails complex social and environmental aspects. In this study, we investigate the main drivers of marine fish landings in continental Portugal between 1989 and 2014. To identify common trends in time series, and quantify the importance of environmental factors, we applied a dynamic factor analysis considering four regions and three types of gear (trawling, purse-seine, and a multi-gear fishery). Our results show the importance of fishing effort as the most relevant factor driving marine landings in Portugal, both... |

L'Espagne et le Portugal sont de gros consommateurs de produits de la mer avec 42 et 60 kg par habitant et par an, respectivement. Ces deux pays accueillent également un important flux de tourisme, principalement sur les régions côtières. Enfin, comme le reste des pays européens, l'Espagne et le Portugal sont confrontés à une stagnation des apports de la pêche malgré l'accroissement de l'effort, y compris dans les petits fonds (moins de 50 m), normalement interdits de chalutage. C'est dans ce contexte que l'Espagne et le Portugal ont engagé depuis une douzaine d'années des programmes d'immersion de récifs à une échelle importante: - 87 projets réalisés, plus une dizaine en cours de mise en oeuvre - environ 973 km2 de zones protégées du chalutage illégal -... |

Coming from Oriental Asia and Siberia, the Cyprinidae reached the Iberic Peninsula probably at the end of the Oligocene. Their populations bore speciation processes which led to the formation of a fauna rich in endemic species and subspecies. Populations of two of the genera Barbus and Pseudophoxinus reached Northwestern African forming there several endemic species. Concerning the speciation forms, it is probable that the allopatric form, whether by foundation effect or by subdivision, played an important part. Pyrenees and Mediterranean Sea settled probably efficient barriers for the Iberic Cyprinidae isolation. The present geographical repartition of Cyprinidae in Iberic Peninsula suggests that altitude lines and glaciations which reached the north of... |

Next to the wide-spread Candidula gigaxii (Pfeiffer, 1848) and C. intersecta (Poiret, 1801), four endemic Candidula species are reported from Portugal and characterized conchologically, viz. C. belemensis (Servain, 1880) (provisionally), C. codia (Bourguignat, 1859), C. olisippensis (Servain, 1880) and C. setubalensis (Pfeiffer, 1850). Several nominal taxa are classified in the synonymy of these six species, after topotypes (that might be syntypes) or lectotypes. |
