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...

Invasive crayfishes as a threat to freshwater bivalves: Interspecific differenc...
Meira, Alexandra; Lopes-Lima, Manuel; Varandas, Simone; Teixeira, Amílcar; Arenas-Arenas, Francisco José; Sousa, RonaldoFreshwater bivalves have suffered major global declines, being the introduction of invasive alien species (IAS) an important, but not well studied, mechanism of threat. This study assessed the predator-prey relationship between two non-native crayfish species (Procambarus clarkii and Pacifastacus leniusculus) and three native (Anodonta anatina, Potomida littoralis and Unio delphinus) and one non-native (Corbicu...
Invasive crayfishhes as a threat to native freshwater bivalves
Sousa, Ronaldo; Meira, Alexandra; Arenas-Arenas, Francisco José; Lopes-Lima, Manuel; Varandas, Simone; Teixeira, AmílcarProcambarus clarkii and Pacifastacus leniusculus are problematic invasive species and may affect freshwater bivalves. In this study we verified ifthese crayfish species can predate native (Anodonta anatína, Potomida littoralis and Unio delphinus) and non-native (Corbicula fluminea) bivalves through experiments in laboratory and validation in the field (Sabor basin, North of Portugal). In the laboratoiy, crayfis...
