In the trail of “Maçã de Alcobaça” protected geographical indication (PGI): Mul...
Duarte, Bernardo; Melo, Juliana; Mamede, Renato; Carreiras, João; Figueiredo, Andreia; Fonseca, Vanessa F.; de Sousa, Miguel Leão; Silva, Anabela B.Food fraud associated with the intentional mislabelling of non-Protected Geographical Indication (PGI) is a concern for consumers. “Maçã de Alcobaça” (Alcobaça apple) is one of the oldest Portuguese PGI products, characteristic of the main apple-growing regions in the country, being of utmost importance to develop traceability and authenticity tools to depict the PGI certification status of these products. Pulp...
Mapping the macrofauna communities of Portugal's continental shelf north of Naz...
Mamede, Renato; Sampaio, Leandro; Ricardo, Fernando; Magalhães, Luísa; Lopes, Marta; Martins, Roberto; Rodrigues, Ana Maria; Freitas, RosaThe conservation and sustainable use of marine ecosystems is a worldwide concern, and to achieve it, managers and decision-makers require detailed environmental and biological information, namely supplied as maps of the seafloor. This work was conducted on Portugal’s continental shelf located north of Nazar´e Canyon. Sediment data was obtained in 226 grab samples, of which 169 were used to study the macroinvert...
Site-specific lipidomic signatures of sea lettuce (Ulva spp., Chlorophyta) hold...
Costa, Elisabete da; Ricardo, Fernando; Melo, Tânia; Mamede, Renato; Abreu, Maria H.; Domingues, Pedro; Domingues, M. Rosário; Calado, RicardoThe wild harvest and aquaculture of Ulva spp. has deserved growing attention in Europe. However, the impact of geographical origin on the biochemical composition of different species and/or strains is yet to be described in detail. Hence, the present study aimed to detect the variability of the lipidome of different species and/or strains of Ulva originating from different geographic locations. We hypothesized ...
Cost-efficiency improvement of bivalves shells preparation when tracing their g...
Ricardo, Fernando; Mamede, Renato; Bispo, Regina; Santos, Andreia Sofia; Ferreira da Silva, Eduardo; Patinha, Carla; Calado, RicardoDeveloping methodologies employed to trace the geographic origin of seafood as accurate and fast as possible can help to speed-up the delivery of results to legal authorities, reduce associated costs and minimize environmental impacts (associated with the residues generated). The present study evaluated if trace element fingerprints (TEF) of a small homogenized subsample of Manila clams (Ruditapes philippinarum...
Revealing the illegal harvesting of Manila clams (ruditapes philippinarum) usin...
Mamede, Renato; Ricardo, Fernando; Santos, Andreia; Díaz, Seila; Santos, Sónia A.O.; Bispo, Regina; Domingues, M. Rosário M.; Calado, RicardoThe Manila clam (Ruditapes philippinarum) is one of the most traded bivalves in the world. Knowing its harvesting location is therefore paramount to guarantee the safety of consumers. The present study employs fatty acid (FA) profiles of the adductor muscle (AM) to reveal the most likely harvesting location of four batches of Manila clams suspected of having been illegally sourced from the Tagus estuary. In thi...
Remote sensing of underwater vegetation using single-beam acoustics
Quintino, Victor; Freitas, Rosa; Mamede, Renato; Ricardo, Fernando; Rodrigues, Ana Maria; Mota, Jorge; Pérez-Ruzafa, Ángel; Marcos, ConcepciónA single-beam, acoustic, ground-discrimination system (QTC VIEW, Series V) was used to study the distribution of underwater macrophytes in a shallow-water coastal system, employing frequencies of 50 and 200 kHz. The study was conducted in Mar Menor, SE Spain, where the expansion of Caulerpa prolifera has contributed to the silting up of the superficial sediments. A direct relationship was identified between algal...
