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...
Freshwater fish community assessment using eDNA metabarcoding vs. capture-based...
Curto, Manuel; Batista, Sofia; Santos, Carlos D.; Ribeiro, Filipe; Nogueira, Sofia; Ribeiro, Diogo; Prindle, Benjamin; Licari, Daniel; Riccioni, GiuliaEnvironmental DNA (eDNA) metabarcoding has revolutionized ecological and environmental research by describing communities without relying on direct observations, making it a powerful, non-invasive, and cost-effective tool in biodiversity monitoring. However, the adoption of eDNA as a standard protocol in long-term monitoring programs, which have traditionally relied on capture-based methods, presents challenges...
Environmental DNA Template Variation: Its Relevance for Species Detection and C...
Nogueira, Sofia; Curto, Manuel; Dias, Diogo; Alves, Maria Judite; Amaral, Susana Dias; Magalhaes, Maria Filomena; Carrapato, Carlos; Veríssimo, AnaAccurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk. Samples may contain low DNA concentrations of the target taxa and/or exhibit hi...

Genetic diversity in the American elephantfish (Chimaeriformes: Callorhinchus c...
Erk, Cornelia Pia; Concha, Francisco J.; Awruch, Cynthia; Finucci, Brittany; Cristiani, Franco; Guzmán‐Castellanos, Ana B.; Silva, Charlene daUnderstanding genetic population structure and connectivity is essential for effective species-specific management and conservation strategies. The American elephantfish Callorhinchus callorynchus is targeted and retained as incidental catch in commercial and recreational fisheries in Chile and Argentina. Its wide-ranging distribution across southern South America may require transnational co-operation to ensur...
eDNA metabarcoding reveals a rich but threatened and declining elasmobranch com...
de la Hoz Schilling, Carolina; Jabado, Rima W.; Veríssimo, Ana; Caminiti, Luca; Sidina, Ebaye; Gandega, Cheikhna Yero; Serrao, EsterElasmobranchs (sharks and rays) are the most threatened marine vertebrates, particularly in tropical and subtropical areas. Their population status is often poorly understood due to insufficient information. Despite reportedly harbouring critical elasmobranch habitats, the Banc d'Arguin National Park (PNBA) in Mauritania lacks comprehensive and updated information on the diversity of elasmobranch species in the...
Dataset of the complete mitogenome of the deep-sea sailfin roughshark, Oxynotus...
Matos, Ana; Gomes-dos-Santos, André; Graça Aranha, Sofia; Dias, Ester; Veríssimo, Ana; Teodosio, Maria; Figueiredo, Ivone; Castro, L. Filipe C．Chondrichthyans comprise a diverse group of vertebrate species with extraordinary ecological relevance. Yet, multiple members of this evolutionary lineage are associated with sig-nificant extinction risk. The sailfin roughshark Oxynotus para-doxus is a deep-water benthic shark currently listed as vul-nerable due to population declines in parts of its range. Here we provide the first complete mitochondrial genom...
The complete mitochondrial genome of the endemic Iberian pygmy skate Neoraja ib...
Gomes-dos-Santos, André; Machado, André M.; Graça Aranha, Sofia; Dias, Ester; Veríssimo, Ana; Castro, L. Filipe C.; Froufe, ElsaSkates, Chondrichthyes fishes from order Rajiformes, are the most species-rich group of all Batoidea. However, their phylogenetic relationships and systematics is still a highly discussed and controversial subject. The use of complete mitogenome has shown to be a promising tool to fill this gap of knowledge. Here, the complete mitogenome of the Iberian pygmy skate Neoraja iberica (Stehmann, Séret, Costa & Baro ...
A haplotype-resolved draft genome of the European sardine (Sardina pilchardus)
Louro, Bruno; De Moro, Gianluca; Garcia, Carlos; Cox, Cymon; Veríssimo, Ana; Sabatino, Stephen J.; Santos, António M.; Canario, A.V.M.The European sardine (Sardina pilchardus Walbaum, 1792) is culturally and economically important throughout its distribution. Monitoring studies of sardine populations report an alarming decrease in stocks due to overfishing and environmental change, which has resulted in historically low captures along the Iberian Atlantic coast. Important biological and ecological features such as population diversity, struct...
Taxonomic re-evaluation of the non-native cichlid in Portuguese drainages
Carecho, João; Baduy, F.; Silva, FBV; Guerreiro, Pedro; Saraiva, João L.; Ribeiro, Filipe; Veríssimo, AnaA non-native cichlid fish firstly reported in Portugal in 1940 was originally identified as Cichlasoma facetum (Jenyns 1842) based on specimens reported from “Praia de Mira” (Vouga drainage, northwestern Portugal). Currently, the species is known only from three southern Portuguese river drainages, namely Sado, Arade and Guadiana, and no other record has been made from Praia de Mira or the Vouga drainage since ...
