The mitochondrial genomes of Iberian freshwater and diadromous fishes
Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; Almeida, Pedro Raposo de; Aparicio, Enric; Clavero, Miguel; Chaves, CátiaThe Iberian Peninsula, in southwestern Europe, is home to a distinctive freshwater fish fauna, predominantly composed of endemic species. This is a consequence of the prolonged isolation from western Europe caused by the Pyrenees, the diverse geological and climatic gradients, and the isolation of river basins. Freshwater and diadromous fishes have diversified in the Iberian Peninsula and include 72 currently r...
Restocking trials with hatchery-reared dusky groupers in a marine protected are...
Silva, Ana Filipa; Horta e Costa, Barbara; Costa, José Lino; Pereira, Esmeralda; Marques, João Pedro; Castro, João J.; Lino, Pedro G.Marine Protected Areas (MPAs) have played an important role in the protection of endangered species such as the dusky grouper (Epinephelus marginatus), and the no-take areas have been particularly crucial for this purpose. Yet, despite the establishment of no-take areas and the legislation banning dusky groupers’ catches since 2011 in a southwestern Portuguese MPA (SACVMP—‘Sudoeste Alentejano’ and ‘Costa Vicent...
Biologia aquática: o Mira e a região costeira alentejana
Costa, José Lino; Castro, João J.; Cartaxana, Alexandra; Adão, Helena; Paula, José; Magalhães, Maria Filomena; Chainho, Paula; Almeida, Pedro Raposo deEmbora existam alguns trabalhos pontuais pioneiros anteriores a 1980, foi a partir desta data que se intensificaram os estudos sobre as comunidades vegetais e animais do rio e do estuário do Mira. Em água doce, estes trabalhos têm incidido preferencialmente sobre a comunidade piscícola, embora mais recentemente os macroinvertebrados bentónicos tenham começado a ser alvo de uma atenção particular, devido à sua i...
Changes in fish assemblage structure after implementation of Marine Protected A...
Pereira, Tadeu José; Manique, Joana; Quintella, Bernardo; Castro, Nuno; Almeida, Pedro Raposo de; Costa, José LinoMarine Protected Areas (MPAs) are increasingly being recommended as management tools for biodiversity conservation and fisheries. With the purpose of protecting the region's biodiversity and prevent the over exploitation of marine resources, in February 2011 the no-take MPAs of Ilha do Pessegueiro and Cabo Sardão were implemented within the "Parque Natural do Sudoeste Alentejano e Costa Vicentina" (PNSACV) Mari...
Changes in trophic ecology of fish assemblages after no take Marine Protected A...
Pereira, Tadeu José; Manique, Joana; Quintella, Bernardo; Castro, Nuno; Almeida, Pedro Raposo de; Costa, José LinoChanges in fish assemblage structure caused by human activities, such as fishing, can alter trophic relations in fish assemblages. In this context, Marine Protected Areas (MPA) are efficient tools for habitat recovery and ideal environments for evaluating changes on the trophic structure resulting from human activities. The present work targeted fish assemblages from two no-take MPAs from the northern half of S...
Movements of Diplodus sargus (Sparidae) within a Portuguese coastal Marine Prot...
Belo, Ana Filipa; Pereira, Tadeu; Quintella, Bernardo; Castro, Nuno; Costa, José Lino; Almeida, Pedro Raposo deMark-recapture tagging and acoustic telemetry were used to study the movements of Diplodus sargus within the Pessegueiro Island no-take Marine Protected Area (MPA), (Portugal) and assess its size adequacy for this species' protection against fishing activities. Therefore, 894 Diplodus sargus were captured and marked with conventional plastic t-bar tags. At the same time, 19 D. sargus were tagged with acoustic t...
Metal speciation in salt marsh sediments: Influence of halophyte vegetation in ...
Pedro, Silvia; Duarte, Bernardo; Almeida, Pedro Raposo de; Caçador, IsabelSalt marshes provide environmental conditions that are known to affect metal speciation in sediments. The elevational gradient along the marsh and consequent differential flooding are some of the major factors influencing halophytic species distribution and coverage due to their differential tolerance to salinity and submersion. Different species, in turn, also have distinct influences on the sediment's metal s...
Metal partitioning and availability in estuarine surface sediments: Changes pro...
Pedro, Sílvia; Duarte, Bernardo; Reis, Givaldo; Pereira, Eduarda; Duarte, Armando C.; Costa, José Lino; Caçador, Isabel; Almeida, Pedro Raposo deSeveral works have evidenced in the past the importance and influence of plants and terrestrial invertebrates in metal availability in soils and sediments through changes in metal speciation. In contrast, the impact of estuarine invertebrates and fishes in this process has been poorly explored. The partition of metals in estuarine surface sediments was studied in a controlled environment according to four opera...

Costa, Maria José; Almeida, Pedro Raposo de; Costa, José Lino; Silva, Gilda; Azeda, Carla; Paulo Medeiros, João; Sá, EricaDevido à sua íntima associação com o substrato, ao razoável sedentarismo que exibem e ao facto de apresentarem genericamente ciclos de vida relativamente curtos, as espécies que constituem as comunidades bentónicas, e os macroinvertebrados em particular, respondem de forma directa e bastante rápida mesmo a pequenas alterações no meio aquático (Pereira et al., 1998). De facto, os macroinvertebrados são bastante ...
