The European Reference Genome Atlas: piloting a decentralised approach to equit...
Mc Cartney, Ann M.; Formenti, Giulio; Mouton, Alice; De Panis, Diego; Marins, Luísa S.; Leitão, Henrique G.; Diedericks, Genevieve; Kirangwa, JosephA genomic database of all Earth’s eukaryotic species could contribute to many scientific discoveries; however, only a tiny fraction of species have genomic information available. In 2018, scientists across the world united under the Earth BioGenome Project (EBP), aiming to produce a database of high-quality reference genomes containing all ~1.5 million recognized eukaryotic species. As the European node of the ...
Conservation challenges imposed by evolutionary history and habitat suitability...
Reis, Joaquim; Perea, Silvia; Gama, Mafalda; Mendes, Sofia L.; Sousa, Vitor C.; Lima, Cristina S.; Banha, Filipe; Gil, Maria; Alvarez, Maria GarciaClimate change and associated shifts in temperature and precipitation patterns have become an increasing concern as drivers of ongoing biodiversity loss. The Mediterranean region is particularly vulnerable, being both a biodiversity hotspot and a region very prone to desertification. Freshwater mussels are amongst the most threatened invertebrate taxa worldwide. Unio tumidiformis is an endemic and endangered sp...

Multilocus phylogeny and systematics of Iberian endemic Squalius (Actinopterygi...
Perea, Silvia; Santos, Carla Sousa; Robalo, Joana; Doadrio, IgnacioInferring the evolutionary history of a group of species can be challenging given the many factors involved. In recent years, the increased availability of sequences of multiple genes per species has spurred the development of new methodologies to analyse multilocus data sets. Two approaches that analyse such data are concatenated supermatrix and coalescent-based species-tree analyses. In this study, we used bo...
The potential of Aeromonas spp. from wildlife as antimicrobial resistance indic...
Grilo, Miguel; Santos, Carla Sousa; Robalo, Joana; Oliveira, ManuelaDeclines in freshwater fish populations are occurring at a fast rate, increasing the importance of ex-situ conservation programs supported by sound knowledge of population dynamics and life-history traits of the target species. We analysed the growth and age structure of wild and captive stocks of the western ruivaco Achondrostoma occidentale, a Portuguese endangered cyprinid, targeted for captive breeding and ...
Fish diversification at the pace of geomorphological changes: evolutionary hist...
Santos, Carla Sousa; Jesus, T. F.; Fernandes, C; Robalo, Joana Isabel; Coelho, Manuela M.The evolutionary history of western Iberian Leuciscinae, obligatory freshwater fish, is directly linked to the evolution of the hydrographic network of the Iberian Peninsula after its isolation from the rest of Europe, which involved dramatic rearrangements such as the transition from endorheic lakes to open basins draining to the Atlantic. Previous phylogenetic research on western Iberian leuciscines, using ma...
Mito-nuclear sequencing is paramount to correctly identify sympatric hybridizin...
Santos, Carla Sousa; Pereira, Ana Martins; Branco, Paulo; Costa, Gonçalo J.; Santos, José M.; Ferreira, Maria Teresa; Lima, Cristina M.Background. Hybridization may drive speciation and erode species, especially when intrageneric sympatric species are involved. Five sympatric Luciobarbus species—Luciobarbus sclateri (Günther, 1868), Luciobarbus comizo (Steindachner, 1864), Luciobarbus microcephalus (Almaça, 1967), Luciobarbus guiraonis (Steindachner, 1866), and Luciobarbus steindachneri (Almaça, 1967)—are commonly identified in field surveys b...

Reproductive success in the Lusitanian toadfish : Influence of calling activity...
Amorim, Maria Clara Pessoa; Conti, Carlotta; Santos, Carla Sousa; Novais, Bruno; Gouveia, Maria D.; Vicente, Joana R.; Modesto, TeresaAcoustic signals are sexual ornaments with an established role on mate choice in several taxa, but not in fish. Recent studies have suggested that fish vocal activity may signal male quality and influence male's reproductive success but experimental evidence is lacking. Here we made two experiments to test the hypothesis that vocal activity is essential for male breeding success in a highly vocal fish, the Lusi...
Broad-scale sampling of primary freshwater fish populations reveals the role of...
Santos, Carla Sousa; Robalo, Joana Isabel; Pereira, Ana Martins; Branco, Paulo; Santos, José Maria; Ferreira, Maria Teresa; Sousa, MónicaBackground. Worldwide predictions suggest that up to 75% of the freshwater fish species occurring in rivers with reduced discharge could be extinct by 2070 due to the combined effect of climate change and water abstraction. The Mediterranean region is considered to be a hotspot of freshwater fish diversity but also one of the regions where the effects of climate change will be more severe. Iberian cyprinids are...
