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...
Differences in substratum preferences and behaviour within the invasive Corbicu...
Szarmach, Daniel; Wiśniewski, Kamil; Kobak, Jarosław; Kakareko, Tomasz; Labecka, Anna Maria; Sousa, Ronaldo Gomes; Poznańska-Kakareko, MałgorzataClams from the Corbicula species complex of Asian origin are invasive all over the world, currently extending their distribution to waters of the natural thermal regime in Central European areas. Features linking the clams to their habitats in newly invaded areas have not been fully examined. These include substratum preferences and mobility, which may be key to determining potential niche overlap with native b...
The silent extinction of freshwater mussels in Portugal
Lopes-Lima, Manuel; Reis, Joaquim; Alvarez, Maria G.; Anastácio, Pedro M.; Banha, Filipe; Beja, Pedro; Castro, Paulo; Gama, Mafalda; Gil, Maria G.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...
Interspecific differences in the physiological condition of native freshwater m...
Modesto, Vanessa; Ilarri, Martina; Castro, Paulo; Carvalho, Francisco; Cavalheri, Thais; Lopes-Lima, Manuel; Teixeira, Amilcar; Ozorio, Rodrigo O. A.The Asian clam Corbicula fluminea has been widely introduced into aquatic ecosystems and may impact the physiological condition and survival of native freshwater mussels. However, very few studies have evaluated this issue quantitatively. To fill this gap, manipulative field experiments were performed to assess two possible mechanisms of impact on native mussels: (i) interspecific interactions, and (ii) C. flum...
Collapse of native freshwater mussel populations: prospects of a long-term study
Nakamura, Keiko; Sousa, Ronaldo Gomes; Mesquita-Joanes, FrancescFreshwater biodiversity is under threat, but long-term quantitative studies showing major demographic declines in invertebrate species are still scarce. Here we focus on a long-term study (2004 to 2019) using four native freshwater mussel species (Order Unionida) colonizing two canals of the Ebro River (Spain). Special attention was given to Pseudunio auricularius (Spengler, 1793), a critically endangered speci...
Streams in the mediterranean region are not for mussels: predicting extinctions...
da Silva, Janine P.; Sousa, Ronaldo Gomes; Gonçalves, Duarte Vasconcelos; Miranda, Rafael; Reis, Joaquim; Teixeira, Amílcar; Varandas, SimoneClimate change is becoming the leading driver of biodiversity loss. The Mediterranean region, particularly southwestern Europe, is already confronting the consequences of ongoing global warming. Unprecedented biodiversity declines have been recorded, particularly within freshwater ecosystems. Freshwater mussels contribute to essential ecosystem services but are among the most threatened faunal groups on Earth. ...
What we know and do not know about the invasive Asian clam Corbicula fluminea
Modesto, Vanessa; Ilarri, Martina; Labecka, Anna M.; Ferreira-Rodríguez, Noé; Coughlan, Neil E.; Liu, Xiongjun; Sousa, Ronaldo GomesCorbicula fluminea is a widespread and problematic invasive bivalve species in many freshwater ecosystems. Here, a systematic literature review was performed to synthesise what is presently known about C. fluminea in relation to its biology, ecology, and management. Of the total 1156 studies analysed, most were conducted in North America and Europe, with a primary focus on toxicology and ecology. In the native ...
An exploration of the hidden endosymbionts of Corbicula in the native range
Bespalaya, Yulia V.; Sousa, Ronaldo Gomes; Gofarov, Mikhail Yu; Kondakov, Alexander V.; Kropotin, Alexander V.; Palatov, Dmitry M.; Vikhrev, Ilya V.[Excerpt] In a sense, a single individual host can be considered an ecosystem. For example, a host may be seen as an environment that can be colonized by a high diversity of entities such as different mutualists, commensals, and parasites.
Fishing for hosts: Larval spurting by the endangered thick-shelled river mussel...
Aldridge, David C.; Brian, Joshua I.; Cmiel, Adam; Lipinska, Anna; Lopes-Lima, Manuel; Sousa, Ronaldo Gomes; Teixeira, Amilcar; Zajac, Katarzyna[Excerpt] Understanding the life-history characteristics of endangered species is crucial to their conservation, management, and predicting their responses to environmental change (Stark et al., 2004). Host specificity is central to the evolutionary diversification and conservation of the Unionida (Barnhart et al., 2008; Modesto et al., 2018). In the North American mussels of the Ambleminae subfamily, specifici...
Joint species distribution models unveil co-occurrences between freshwater muss...
da Silva, Janine P.; Goncalves, Duarte Vasconcelos; Garcia-Raventos, Aina; Lopes-Lima, Manuel; Varandas, Simone; Froufe, Elsa; Teixeira, AmilcarAim: Freshwater 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...
