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...

Connectivity patterns and gene flow among Chelon ramada populations
Pereira, Esmeralda; Mateus, Catarina Sofia; Alves, Maria Judite; Almeida, Rita; Pereira, Joana; Quintella, Bernardo R.; Almeida, Pedro R.Catadromous species, such as the thinlip grey mullet Chelon ramada (Risso 1827), exhibit complex life history traits and migratory behaviours that have different repercussions at the population level and species genetic structure. To study the genetic variation and infer patterns of gene flow and population connectivity along species’ distribution across the Northeast Atlantic coast and the Mediterranean Sea, 4...

Almeida, Pedro R.; Mateus, Catarina Sofia; Alexandre, Carlos M.; Pedro, Sílvia; Boavida-Portugal, Joana; Belo, Ana Filipa; Pereira, EsmeraldaThis work aims to present an historical review of the ecosystem services provided by anadromous fish (i.e., species that migrate from the sea to the river to spawn) throughout Human time, as well as of the main related threats, focusing on the Iberian Peninsula region. Anadromous fish provide important provision, cultural, regulatory and supporting ecosystem services across their distribution range and have bee...

Population structure in anadromous lampreys: Patterns and processes
Mateus, Catarina Sofia; Docker, Margaret; Guillaume, Evanno; Hess, John; Hume, John; Oliveira, Inês; Souissi, Ahmed; Sutton, TrentPopulation structure can reveal the diversity, gene flow, and dispersal of a species. This information can be used to make management decisions and reveal fundamental aspects of an organism’s biology. Distinct intrinsic (e.g., biological characteristics) and extrinsic (e.g., geographical and historical events, environment, human pressures) factors can influence population structure, with significant differences...
European lampreys: new insights on postglacial colonization, gene flow and spec...
Mateus, Catarina Sofia; Almeida, Pedro Raposo; Mesquita, Natacha; Quintella, Bernardo Ruivo; Alves, Maria JuditeIce ages are known to be the most dominant palaeoclimatic feature occurring on Earth, producing severe climatic oscillations and consequently shaping the distribution and the population structure of several species. Lampreys constitute excellent models to study the colonization of freshwater systems, as they commonly appear in pairs of closely related species of anadromous versus freshwater resident adults, thu...
Strong genomewide divergence between sympatric European river and brook lampreys
Mateus, Catarina Sofia; Stange, Madlen; Berner, Daniel; Roesti, Marius; Quintella, Bernardo Ruivo; Alves, Maria Judite; Almeida, Pedro RaposoLampreys, together with hagfishes, are the only extant representatives of jawless vertebrates and thus of prime interest for the study of vertebrate evolution [1]. Most lamprey genera occur in two forms with divergent life histories: a parasitic, anadromous and a non-parasitic, freshwater resident form [2-8]. The taxonomic status of such 'paired species' is disputed, however. While indistinguishable at larval s...
MtDNA markers reveal the existence of allopatric evolutionary lineages in the t...
Mateus, Catarina Sofia; Almeida, Pedro Raposo; Quintella, Bernardo Ruivo; Alves, Maria JuditeThe Iberian Peninsula has been identified as an important glacial refugium during the Pliocene and Pleistocene epochs for the genus Lampetra, providing intermittent refuge and postglacial opportunities for colonization and expansion. We used mitochondrial DNA markers to investigate the processes that have shaped present-day genetic constitution of the genus Lampetra within the Iberian Peninsula. We surveyed 1,1...

Lança, Maria João; Machado, Maria Ana; Mateus, Catarina Sofia; Quintella, Bernardo Ruivo; Almeida, Pedro RaposoThe agnathans probably arose as the first vertebrates about 530 million years ago, in Cambrian period and after the evolutionary “boom” of multicellular organisms. The genus Petromyzon comprises only one anadromous and parasitic species, Petromyzon marinus L., known as sea lamprey which is widely distributed on both sides of the North Atlantic. Sea lamprey migrates twice during its life cycle between freshwater...
