Citizen science and expert judgement: A cost-efficient combination to monitor a...
Parretti, Paola; Monteiro, João Gama; Gizzi, Francesca; Martinez-Escauriaza, Roi; Alves, Filipe; Chebaane, Sahar; Almeida, Silvia; Pais, Miguel PessanhaMapping the distribution and evaluating the impacts of marine non-indigenous species (NIS) are two fundamental tasks for management purposes, yet they are often time consuming and expensive. This case study focuses on the NIS gilthead seabream Sparus aurata escaped from offshore farms in Madeira Island in order to test an innovative, cost-efficient combined approach to risk assessment and georeferenced dispersa...
Gaps in DNA sequence libraries for macaronesian marine macroinvertebrates imply...
Vieira, Pedro Emanuel Ferreira Reis; Lavrador, Ana Sofia Castro; Parente, Manuela I.; Parretti, Paola; Costa, Ana C.; Costa, Filipe O.Aim: DNA metabarcoding has great potential to improve biomonitoring in island's marine ecosystems, which are highly vulnerable to global change and non-indigenous species (NIS) introductions. However, the depth and accuracy of the taxonomic identifications are mainly dependent on reference libraries containing representative and reliable sequences for the targeted species. In this study, we evaluated the gaps i...
A new signal of tropicalization in the Northeast Atlantic: the spread of the sp...
Castro, Nuno; Schäfer, Susanne; Parretti, Paola; Monteiro, João Gama; Gizzi, Francesca; Chebaane, Sahar; Almada, Emanuel; Henriques, FilipeCurrent trends in the global climate facilitate the displacement of numerous marine species from their native distribution ranges to higher latitudes when facing warming conditions. In this work, we analyzed occurrences of a circumtropical reef fish, the spotfin burrfish, Chilomycterus reticulatus (Linnaeus, 1958), in the Madeira Archipelago (NE Atlantic) between 1898 and 2021. In addition to available data sou...
Organic matter composition and macrofaunal diversity in sediments of the Condor...
Bongiorni, Lucia; Ravara, Ascensão; Parretti, Paola; Santos, Ricardo S.; Rodrigues, Clara Lúcia Ferreira; Amaro, Teresa; Cunha, Marina Pais Ribeiro daIn recent years increasing knowledge has been accumulated on seamounts ecology; however their sedimentary environments and associated biological communities remain largely understudied. In this study we investigated quantity and biochemical composition of organic matter and macrofaunal diversity in sediments of the Condor Seamount (NE Atlantic, Azores).In order to test the effect of the seamount on organic matt...
