The mitochondrial genomes of Iberian freshwater and diadromous fishes
Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; de Almeida, Pedro Raposo; 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...
A pegada do “Ouro Líquido” Mediterrânico nos ecossistemas aquáticos: estudo dos...
Costa, Silvana Teixeira; Miranda, Fernando; Teixeira, Fernando; Zidouh, Aya; Fernandes, Conceição; Dias, Luís; Hernandez, Zulimar; Teixeira, AmílcarAtualmente, 80.000 t de bagaço de azeitona são processadas numa única unidade extratora localizada na região de Trás-os-Montes e Alto Douro, produzindo águas-ruças (OMWW) que são altamente fitotóxicas. A falta de medidas de gestão para este resíduo em específico, levanta a importância de compreender como este pode impactar a integridade ecológica dos ecossistemas aquáticos. Assim, oito locais espalhados pelo Ri...
Invasive dynamics of the signal crayfish Pacifastacus leniusculus in a protecte...
Carvalho, Francisco; Alves, Henrique; Pascoal, Cláudia; Castro, Paulo; Miranda, Fernando Jorge Veloso; Teixeira, Amílcar; Cássio, FernandaInvasive species have been drivers of biodiversity loss and functional changes in aquatic ecosystems, including in protected areas. Therefore, monitoring population invasion dynamics and biological traits is fundamental to better understand their ecological and economic impacts and for management actions development. We followed signal crayfish (Pacifastacus leniusculus) invasion in Rabaçal River upper reach at...
Integrative phylogenetic, phylogeographic and morphological characterisation of...
Lopes-Lima, Manuel; Geist, Juergen P.; Egg, S.; Beran, Luboš; Bikashvili, Ani; Van Bocxlaer, Bert; Bogan, Arthur E.; Bolotov, Ivan N.The global decline of freshwater mussels and their crucial ecological services highlight the need to understand their phylogeny, phylogeography and patterns of genetic diversity to guide conservation efforts. Such knowledge is urgently needed for Unio crassus, a highly imperilled species originally widespread throughout Europe and southwest Asia. Recent studies have resurrected several species from synonymy bas...
The complete mitochondrial genome of Potomida acarnanica (Kobelt, 1879)
Matos, Ana; Gomes-dos-Santos, André; Teixeira, Amílcar; Varandas, Simone; Sousa, Ronaldo; Karaouzas, Ioannis; Zogaris, Stamatis; Froufe, ElsaFreshwater mussels (Bivalvia, Unionida) play essential roles in the well-functioning of ecosystems, even providing essential services to humans. However, these bivalves face numerous threats (e.g. habitat loss and fragmentation, pollution, introduction of invasive species, and climate change) which have already led to the extinction of many populations. This underscores the need to fully characterize the biolog...
The role of adaptive resistance in a widespread freshwater mussel species
Santos, Rogério; Sousa, Ronaldo; Lopes-Lima, Manuel; Teixeira, AmílcarOrganism features, such as size, weight, sex and age, among others, can influence the success of parasitism. For species that depend on a host to complete their life cycle, such as freshwater mussels (Bivalvia, Unionida), understanding how these traits influence parasitism can help guide management actions aimed at improving their reproductive success, ultimately benefitting their conservation. In this study, t...
The silent extinction of freshwater mussels in Portugal
Lopes-Lima, M.; Reis, J.; Alvarez, Maria G.; Anastácio, P. M.; Banha, F.; Beja, P.; Castro, P.; Gama, Mafalda; Gil, M. G.; Gomes-dos-Santos, A.Freshwater mussels are one of the most threatened animal groups in the world. In the European Union, threatened and protected mussel species are not adequately monitored, while species considered to be common and widespread receive even less attention. This is particularly worrying in the Mediterranean region, where species endemism is high and freshwater habitats are severely affected by water scarcity. In the...
Joint species distribution models unveil co-occurrences between freshwater muss...
Silva, Janine P.; Goncalves, Duarte Vasconcelos; Garcia-Raventós, Aina; Lopes-Lima, Manuel; Varandas, Simone; Froufe, Elsa; Teixeira, AmílcarFreshwater mussels are among the most threatened taxa in the world, partially due to the dependence on fish hosts to complete their life cycle. Knowledge about the role of environmental and biotic drivers in determining mussels' distribution is currently lacking. We aimed to assess the role of environmental and biotic drivers in determining the distribution of mussels and their fish hosts and to test if co-occu...
A roadmap for the conservation of freshwater mussels in Europe
Sousa, Ronaldo; Zając, Tadeusz; Halabowski, Dariusz; Aksenova, Olga V.; Bespalaya, Yulia V.; Carvalho, Francisco; Castro, Paulo S.; Douda, KarelEurope has a long history of human pressure on freshwater ecosystems. As pressure continues to grow and new threats emerge, there is an urgent need for conservation of freshwater biodiversity and its ecosystem services. However, whilst some taxonomic groups, mainly vertebrates, have received a disproportionate amount of attention and funds, other groups remain largely off the public and scientific radar. Freshw...
Identifying freshwater priority areas for cross-taxa interactions
Nogueira, Joana Garrido; Lopes-Lima, Manuel; Beja, Pedro; Filipe, Ana Filipa; Froufe, Elsa; Gonçalves, Duarte V.; Silva, Janine P.; Sousa, RonaldoInformation about biotic interactions (e.g. competition, predation, parasitism, diseases, mutualism, allelopathy) is fundamental to better understand species distribution and abundance, ecosystem functioning, and ultimately guide conservation efforts. However, conservation planning often overlooks these important interactions. Here, we aim to demonstrate a new framework to include biotic interactions into Marxa...
