- Molecular insights into spined loaches (Cobitidae: Cobitis) reveal the complex evolutionary history of freshwater fishes in the Iberian Peninsula and North AfricaPublication . Perdices, Anabel; Queirós, João; Alves, Maria Judite; Alves, Paulo Célio; Beja, Pedro; Buckley, David; Clavero, Miguel; Coelho, Maria Manuela; Filipe, Ana Filipa; Froufe, Elsa; Magalhães, Maria Filomena; Nogueira, Joana Garrido; Oliveira, João Manuel; Pou-Rovira, Quim; Sousa, Ronaldo; Suh, Jongmo; Teixeira, Amilcar; Varandas, Simone; Ventura, Marc; Veríssimo, Joana; Lopes-Lima, ManuelPalaeogeographic and tectonic rearrangements of rivers have significantly influenced the phylogeography of Iberian and North African freshwater fishes, but their impact remains unclear. We revisit the phylogeographic relationships and diversification timelines of Cobitis (spined loaches, family Cobitidae) on both sides of the Strait of Gibraltar. Sampling 230 sites across 41 river basins, we analysed genetic variability using haplotype networks of two mitochondrial (Cytb and COI) and two nuclear (S7 and RAG-1) genes. A time-calibrated multilocus phylogeny was constructed and compared with the evolution timeline of the Iberian hydrographic network. Our results indicate that Iberian and North African Cobitis are monophyletic at the mitochondrial, but not at the nuclear level. Three new mitochondrial lineages, potentially new species, were identified in Iberia (2) and Morocco (1). Most Iberian Cobitis show wide distributions and frequent sympatry in major basins. Diversification started in the Mid-Late Miocene (7.9–8.9 Mya), with major speciation during the Late Miocene–Pliocene transition (6.5–5.7 Mya). Palaeographic changes in river basins, from endorheic to exorheic regimes, probably affected Cobitis speciation. Tectonic strike-slip faults probably influenced isolation, genetic mixing, and incomplete lineage sorting, particularly along Atlantic margins. These results highlight the interplay of geological and evolutionary processes in shaping freshwater fish diversity.
- The mitochondrial genomes of Iberian freshwater and diadromous fishesPublication . Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; Almeida, Pedro Raposo de; Aparicio, Enric; Clavero, Miguel; Chaves, Cátia; Fernandez-Delgado, Carlos; Hernández, Jesús; Jentoft, Sissel; Kalous, Lukáš; Magalhães, Maria Filomena; Martins, Filipa MS; Mateus, Catarina Sofia; Nogueira, Joana Garrido; Oliveira, Inês; Perdices, Anabel; Rocaspana, Rafel; Ribeiro, Filipe; Risueño, Pilar; Rovira, Quim Pou i; Queirós, João; Santos, Carlos David; Teixeira, Amilcar; Veríssimo, Ana; Volta, Pietro; Beja, Pedro; Gante, Hugo F.; Lopes-Lima, ManuelThe 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 recognized native species, 50 of which are endemic to the region. Habitat loss and degradation, the introduction of invasive species, and climate change have placed Iberian freshwater and diadromous fishes among the most threatened groups of vertebrates, with some species on the brink of extinction. Here, we present 60 new complete mitochondrial genome assemblies out of the 109 freshwater and diadromous fish species found in the Iberian Peninsula, including the mitogenomes of 37 endemics. These resources are crucial for characterising the mitochondrial evolution of species, reconstructing phylogeny and paleogeography, advancing species identification, delineation, and monitoring, and ultimately supporting conservation planning.
