The mitochondrial genomes of Iberian freshwater and diadromous fishes
Veríssimo, Joana; Curto, Manuel; Alves, Maria Judite; Almeida, Pedro Raposo de; 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...
Intrapopulation differences in biological traits and impacts in a highly invasi...
Alves, Henrique; Gonçalves, Diana; Nogueira, António Barbosa; Teixeira, Amilcar; Padilha, Janeide; Sousa, RonaldoIndividual variation assessments are essential to better understand population and community dynamics, as well ecosystem functioning. Although researchers have long recognized this aspect, only recently has evidence accumulated about the ecological importance of variation within species. The incorporation of individual variation provides an even more complete description of the effects a species may have on eco...
Navigating Methodological Trade‐Offs in eDNA Metabarcoding Biodiversity Monitor...
Veríssimo, Joana; Lopes‐Lima, Manuel; Amaral, Fábio; Chaves, Cátia; Fernandes, Vasco; Kemanja, Mutaleni; Teixeira, Amilcar; Martins, Filipa M. S.Environmental DNA (eDNA) metabarcoding technologies promise significant advances in biodiversity monitoring, yet their application requires extensive optimisation and standardisation. Recent research demonstrated that increased sampling and analytical efforts are needed to improve biodiversity estimates, though fully optimising study designs is often hindered by resource constraints. Consequently, researchers m...
Trophic response of brown trout to signal crayfish invasion in a protected moun...
Matos, Matilde; Teixeira, Amilcar; Nogueira, António B.; Padilha, Janeide; Sousa, RonaldoWe investigated the dietary response of brown trout (Salmo trutta) to the invasion of the signal crayfish (Pacifastacus leniusculus) in the Baceiro River (Montesinho Natural Park, Portugal). We analyzed 1012 stomach contents across six sites (five invaded and one non-invaded) over the year of 2023. A total of 49 distinct dietary taxa were identified. Results reveal strong spatial and temporal variation in trout...
A curated dataset on the distribution of West Palaearctic freshwater bivalves
Lopes-Lima, Manuel; Aldridge, David C.; Álvarez, María G.; Araujo, Rafael; Barea-Azcón, José Miguel; Bikashvili, Ani; Bragado, Dolores; Bylyna, LiliaFreshwater bivalves (FWB) are attracting scientific and societal attention given their essential ecosystem services, ecological functions, and poor conservation status. Current knowledge of the spatial distribution of West Palearctic FWB is poor preventing the understanding of biogeography and conservation planning. One of the priorities of the pan-European networking project "CONFREMU - Conservation of freshwa...
Cold tolerance strategies of freshwater mussels across latitudes
Lipińska, Anna M.; Adamski, Paweł; Ćmiel, Adam M.; Golab, Maria J.; Idczak-Figiel, Paulina A.; Lopes-Lima, Manuel; Mageroy, Jon H.; Nowakowska, AnnaFreshwater mussels across Europe exhibit physiological and behavioural adaptations to survive winter conditions. Climate change projections, including more frequent extreme weather events, are expected to intensify pressures on these ecosystems. In this study, we tested the temperature-size hypothesis, which posits that larger body size in ectothermic organisms is an adaptation to colder climates. We predicted ...
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...
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...
Identifying freshwater priority areas for cross-taxa interactions
Nogueira, Joana Garrido; Lopes-Lima, Manuel; Beja, Pedro; Filipe, Ana Filipa; Froufe, Elsa; Goncalves, Duarte, V; da Silva, Janine P.Information 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...
