Engaging and legitimizing communities: co-designing a community-based Marine Pr...
Rangel, Mafalda; Costa, Barbara Horta e; Guimarães, Mª Helena; Ressurreição, Adriana; Monteiro, Pedro; Oliveira, Frederico; Bentes, LuísMarine Protected Areas are increasingly used as tools to preserve marine habitats and biodiversity worldwide. Nonetheless, creating MPAs in densely populated multi-use coastal areas comes with intrinsic conflict potential, since protection and economic development are not always hand-in-hand and local users might disagree with the designation of such conservation tools. The use of inclusive and transparent part...
Co-design of a marine protected area zoning and the lessons learned from it
Horta e Costa, Barbara; Guimarães, M. Helena; Rangel, M; Ressurreicao, Adriana; Monteiro, Pedro; Oliveira, Frederico; Bentes, LuisMarine Protected Areas (MPAs) are a tool to safeguard marine natural systems, yet their effectiveness depends on how well they are integrated into the existing socioeconomic context. Stakeholder engagement in MPA design can contribute to increasing integration. This study focuses on the co-design of an MPA between researchers, public administration, the private sector, and non-governmental organizations. The pr...
Setting performance indicators for coastal marine protected areas: An expert-ba...
Cardoso-Andrade, Mariana; Queiroga, Henrique; Rangel, M; Sousa, Inês; Belackova, Adela; Bentes, Luis; Oliveira, Frederico; Monteiro, PedroMarine Protected Areas (MPAs) require effective indicators to assess their performance, in compliance with the goals of relevant national and international commitments. Achieving and prioritizing shortlists of multidisciplinary indicators demands a significant effort from specialists to depict the multiple conservation and socioeconomic interests, and the large complexity of natural systems. The present paper d...
Ecophysiological effects of mercury bioaccumulation and biochemical stress in t...
Rodrigues, Andreia C. M.; Gravato, Carlos; Galvão, Daniela; Silva, Virgília S.; Soares, Amadeu M. V. M.; Gonçalves, Jorge M. S.; Ellis, Jim R.Mercury (Hg) is a non-essential metal that can have toxic effects on the fitness of organisms and tends to bioaccumulate with age and to biomagnify in higher trophic levels. Few studies have assessed oxidative stress and neurotoxicity in deep-water sharks. This study evaluated early ontogenetic changes and physiological effects (antioxidant defences, oxidative damage, aerobic metabolism and neurotransmission fu...
Diet consistency but large-scale isotopic variations in a deep-sea shark: the c...
Besnard, Lucien; Duchatelet, Laurent; Bird, Christopher S.; Le Croizier, Gaël; Michel, Loïc; Pinte, Nicolas; Lepoint, Gilles; Schaal, GauthierDeep-sea elasmobranchs are commonly reported as bycatch of deep-sea fisheries and their subsequent loss has been highlighted as a long-running concern to the ecosystem ecological functioning. To understand the possible consequences of their removal, information on basic ecological traits, such as diet and foraging strategies, is needed. Such aspects have been widely studied through stomach content analysis but ...
Fisher's perceptions about a marine protected area over time
Pita, Cristina Brice; Costa, Barbara Horta e; Franco, Gustavo; Coelho, Rui; Sousa, Inês; Gonçalves, Emanuel João; Gonçalves, Jorge M. S.; Erzini, KarimThe perceptions of fishers towards the Arrábida Marine Park, a marine protected area (MPA) in the west coast of Portugal, were studied through face-to-face interviews in two different moments of the MPA life cycle. Fishers' perceptions about the MPA and the impact it had on the fishing activity over time were identified just before the full implementation of the zoning and regulations of the management plan and...
Seasonal variation of transcriptomic and biochemical parameters of Donax truncu...
Magalhães, Luísa; Montaudouin, Xavier de; Correia, Simão; Daffe, Guillemine; Gonzalez, Patrice; Figueira, Etelvina; Gonçalves, Jorge M. S.The wedge clam (Donax trunculus) is widely distributed along exposed Atlantic coasts, from France to Senegal. This species has high commercial importance, with the mean capture production on the last ten years of approx. 850 tonnes (50% represented by Portugal captures). D. trunculus populations are modulated by several drivers such as tidal range, temperature, sediment grain size, fishing pressure, predation a...
Soft-bottom fishes and spatial protection: findings from a temperate marine pro...
Sousa, Inês; Gonçalves, Jorge M. S.; Claudet, Joachim; Coelho, Rui; Gonçalves, Emanuel João; Erzini, KarimNumerous studies over the last decades have focused on marine protected areas (MPAs) and their effects on fish communities. However, there is a knowledge gap regarding how species that live associated with soft-substrates (e.g., sand, mud) respond to spatial protection. We analyzed abundance, biomass and total lengths of the soft-bottom fishes in a multiple-use MPA in the north-eastern Atlantic, the Luiz Saldan...
The fish fauna of AmpSre Seamount (NE Atlantic) and the adjacent abyssal plain
Christiansen, Bernd; Vieira, Rui P.; Christiansen, Sabine; Denda, Anneke; Oliveira, Frederico; Gonçalves, Jorge M. S.An inventory of benthic and benthopelagic fishes is presented as a result of two exploratory surveys around Ampe`re Seamount, between Madeira and the Portuguese mainland, covering water depths from 60 to 4,400 m. A total of 239 fishes were collected using different types of sampling gear. Three chondrichthyan species and 31 teleosts in 21 families were identified. The collections showed a vertical zonation with...
Lost fishing gear and litter at Gorringe Bank (NE Atlantic)
Vieira, Rui P.; Raposo, Isabel P.; Sobral, Paula; Gonçalves, Jorge M. S.; Bell, Katherine L. C.; Cunha, Marina R.Studies concerning marine litter have received great attention over the last several years by the scientific community mainly due to their ecological and economic impacts in marine ecosystems, from coastal waters to the deep ocean seafloor. The distribution, type and abundance of marine litter in Ormonde and Gettysburg, the two seamounts of Gorringe Bank, were analyzed from photo and video imagery obtained duri...
