CAMPANHA DE RASTREIO ACÚSTICO “PELAGO23” SÉRIE PNAB/DCF – PELAGO (Primavera)
Anxo Conde; Angélico, Maria Manuel; Pablo Carrera,; Henriques, Elisabete; Elisabete Henriques,; Elisabete Henriques,; Mendes, Hugo; Oliveira, Paulo B.O objetivo da campanha PELAGO23 foi determinar a distribuição espacial da sardinha, biqueirão e cavala, e estimar a sua abundância e biomassa, assim como avaliar a estrutura da comunidade de peixes pelágicos, a distribuição e abundância de ovos e larvas, o censo de aves e mamíferos e a caracterização das condições ambientais na plataforma continental portuguesa e Baia de Cádis. A campanha decorreu de 15 de març...
Spatial and temporal variations of Cockle (Cerastoderma spp.) populations in tw...
Santos, Cátia; Cabral, Sara; Carvalho, Frederico; Sousa, António; Goulding, Thomas; Ramajal, João; Medeiros, João Paulo; Silva, GildaCockles are amongst the most exploited bivalve species in Portugal, playing an important ecological and socioeconomic role in coastal ecosystems. Two sympatric species of cockles, Cerastoderma edule (Linnaeus, 1758) and Cerastoderma glaucum (Bruguiere, 1789-1792) may co-occur in estuaries and coastal lagoons in mixed populations along the European Atlantic coast, namely in Portugal, France and the United Kingdo...
Allochthonous-derived organic matter subsidizes the food sources of estuarine j...
Morais, Pedro; Dias, Ester; Cruz, Joana; Chainho, Paula; Angélico, Maria Manuel; Costa, J.L.; Barbosa, Ana B; Teodósio, Maria AlexandraJellyfish modulate the energy fluxes between compartments of aquatic ecosystems and the period that energy remains within each compartment. However, the contribution of different sources of organic matter (OM) to the production of most estuarine jellyfish species is unknown. Therefore, this study aimed to identify and quantify the putative sources of OM for Blackfordia virginica (Cnidaria, Hydrozoa) Mayer, 1910...
Ecological aspects and potential impacts of the non-native hydromedusa Blackfor...
Marques, Filipa; Angélico, Maria Manuel; Costa, José Lino; Teodósio, Maria Alexandra; Presado, Patrícia; Fernandes, António; Chainho, PaulaThe hydrozoan Blackfordia virginica has been reported over a wide geographical area, although it is mainly restricted to scattered records within estuarine areas of temperate and tropical regions. The aim of this study was to understand the spatial and temporal variability of an established population of this non-indigenous species on a temperate estuarine ecosystem, and its impacts over the plankton community....
Essential habitat for sardine juveniles in Iberian waters
Rodríguez-Climent, Sílvia; Angélico, Maria Manuel; Marques, Vítor; Oliveira, Paulo; Wise, Laura; Silva, AlexandraIn a period when the Iberian sardine stock abundance is at its historical minimum, knowledge of the sardine juvenile’s distribution is crucial for the development of fishery management strategies. Generalized additive models were used to relate juvenile sardine presence with geographical variables and spawning grounds (egg abundance) and to model juvenile abundance with the concurrent environmental conditions. ...

Cabral, Henrique; Costa, José Lino; Chainho, Paula; Marques, Filipa; Portela, Teresa; Ruano, Francisco; Angélico, Maria Manuel; Lourenço, HelenaO projeto CRASSOSADO nasceu do desafio lançado pelo ICNF - RNES às instituições científicas portuguesas com trabalhos de investigação recentes sobre as populações portuguesas de ostra, nomeadamente o MARE/FCUL, a Universidade de Aveiro/CESAM e o IPMA, tendo sido solicitado que se identificassem e estudassem os aspetos mais prementes para assegurar a conservação e a exploração sustentada deste recurso no estuári...
What are jellyfish really eating to support high ecophysiological condition?
Morais, Pedro; Parra, María Parra; Marques, Raquel; Cruz, Joana; Angélico, Maria Manuel; Chainho, Paula; Costa, José Lino; Barbosa, Ana B.The feeding ecology of Blackfordia virginica was evaluated concurrently with their ecophysiological condition in a temperate estuary. The diet of B. virginica is composed not only of metazooplankton, as commonly observed for other jellyfish species, but also of phytoplankton, ciliates and detritus. This feeding behavior might explain their good nutritional condition and sustainable growth during bloom peaks, wh...
