Recovery after exploitation of stalked barnacles is facilitated by the presence...
Gómez‑del Campo, V; Arrontes, J; Cruz, T; Vázquez, E; Macho, G; Thiébaut, E; Geiger, K; Fernandes, J; Jacinto, D; Aguión, A; Silva, T; Mateus, DWe have followed the recovery of gaps produced either by harvesters or by scientists in stands of stalked barnacle (Pollicipes pollicipes) during two years in four regions of Europe (SW Portugal, Galicia and Asturias in Spain and Brittany in France; n = 423 gaps), which was extended to four years in Asturias (n = 252 gaps). The presence of adult conspecifics in the margins of the gaps increased by at least four...
An acclimatization period in a cage promotes site fidelity of hatchery-reared d...
Silva, AF; Castro, JJ; Pereira, E; Marques, JP; Silva, T; Lino, PG; Candeias-Mendes, A; Pousão-Ferreira, P; Pinto, B; Costa, JL; Almeida, PRThe influence of an in-situ acclimatization period of five weeks, seeking the settlement and fidelity of hatchery-reared dusky groupers (Epinephelus marginatus) to the release sites in restocking actions, was tested using acoustic biotelemetry. Eight tagged adult groupers were submitted to the wild conditions in a fish farm cage, while seven remained in the hatchery and tagging location until they were all rele...
Using fish assemblages to assess the ecological effects of marine protection on...
Castro, N; Pereira, TJ; Costa, A; Sertório, J; Fernandes, A; Tavares, MJ; Castro, JJIntensive and regular fishing occurs in the marine area of the natural park “Parque Natural do Sudoeste Alentejano e Costa Vicentina” (PNSACV; SW coast of continental Portugal). In 2011, this area became a marine park with different protection levels (total, partial, and complementary). We assessed in 2011 and 2012 if partial protection (PP) in Marine Protected Areas (MPAs) changed the taxa richness, abundance,...
Setting Performance Indicators for Coastal Marine Protected Areas: An Expert-Ba...
Cardoso-Andrade, M; Queiroga, H; Rangel, M; Sousa, I; Belackova, A; Bentes, L; Oliveira, F; Monteiro, P; Sales Henriques, N; Afonso, CML; Silva, AFMarine 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...
A large‑scale comparison of reproduction and recruitment of the stalked barnacl...
Aguión, A; Cruz, T; Acuña, JL; Broudin, C; Castro, JJ; Davoult, D; Dubert, J; Fernandes, JN; Geiger, KJ; Jacinto, D; Mateus, D; Muñiz, C; Nolasco, RUnderstanding large-scale spatial and temporal patterns of marine populations is a central goal in ecology, which has received renewed attention under climate change. However, few studies explore the large-scale dynamics of populations using standardized protocols and during the same time frames. We studied the phenology and intensity of reproduction and recruitment for the intertidal stalked barnacle Pollicipe...
Pedunculate cirripedes of the genus Pollicipes: 25 years after Margaret Barnes'...
Cruz, T; Jacinto, D; Seabra, MI; Van Syoc, RJ; Power, AM; Macho, G; Sousa, A; Castro, JJ; Hawkins, SJTwenty-five years ago, Margaret Barnes reviewed the genus Pollicipes published in Oceanography and Marine Biology: An Annual Review. Our review complements and updates Barnes (1996). An endemic species of Pollicipes, P. caboverdensis, from Cape Verde Islands, has since been described, joining the three previously known extant species (P. polymerus, northeastern Pacific Ocean, P. elegans, tropical eastern Pacifi...

Professores e Investigadores do Departamento de Biologia, Laboratório de Ciências do Mar (Escola de Ciências e Tecnologia) e MARE – Centro de Ciências do Mar e do Ambiente, da Universidade de Évora, criaram este artigo com o objetivo de contribuir para o enriquecimento da literacia científica sobre o litoral rochoso alentejano.
The intertidal zone of the North-East Atlantic region: pattern and process.
Hawkins, SJ; Pack, KE; Firth, LB; Mieskowska, N; Evans, AJ; Martins, GM; Aberg, P; Adams, LC; Arenas, F; Boaventura, DM; Bohn, K; Borges, CDGThe north-east Atlantic region is an area where clades originating in the north Pacific (fucoids, balanoids, littorinids, thaids, laminarians) collide with clades from further south in the Atlantic (e.g., patellids, trochids, chthamalids). At high latitudes in the north, seaweeds dominate the midshore zone of all but the most exposed shores. Further south, midshore space-occupying invertebrates (mussels and bar...
Diurnal variability of inner-shelf circulation in the lee of a cape under upwel...
Lamas, L; Peliz, A; Dias, J; Oliveira, PB; Angélico, MM; Castro, JJ; Fernandes, JN; Trindade, A; Cruz, TThe nearshore circulation in the lee of a cape under upwelling conditions was studied using in-situ data from 3 consecutive summers (2006–2008). Focus was given to a period between 20 July and 04 August 2006 to study the diurnal variability of the cross-shelf circulation. This period was chosen because it had a steady upwellingfavourable wind condition modulated by a diurnal cycle much similar to sea breeze. Th...
