The recovery of European freshwater biodiversity has come to a halt
Haase, Peter; Bowler, Diana E.; Baker, Nathan J.; Bonada, Núria; Domisch, Sami; Garcia Marquez, Jaime R.; Heino, Jani; Hering, Daniel; Jähnig, Sonja C.Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European coun...
Carbon dioxide fluxes increase from day to night across European streams
Attermeyer, Katrin; Casas-Ruiz, Joan Pere; Fuss, Thomas; Pastor, Ada; Cauvy-Fraunié, Sophie; Sheath, Danny; Nydahl, Anna C.; Doretto, AlbertoGlobally, inland waters emit over 2 Pg of carbon per year as carbon dioxide, of which the majority originates from streams and rivers. Despite the global significance of fluvial carbon dioxide emissions, little is known about their diel dynamics. Here we present a large-scale assessment of day- and night-time carbon dioxide fluxes at the water-air interface across 34 European streams. We directly measured fluxe...
Meta-analysis of multidecadal biodiversity trends in Europe
Pilotto, Francesca; Kühn, Ingolf; Adrian, Rita; Alber, Renate; Alignier, Audrey; Andrews, Christopher; Bäck, Jaana; Barbaro, Luc; Beaumont, DeborahLocal biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15-91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. We test whether (i) local long-term biodiversity trends are consistent among biogeoregions, ...
Is the body condition of the invasive zebra mussel (Dreissena polymorpha) enhan...
Pilotto, Francesca; Sousa, Ronaldo Gomes; Aldridge, David C.The invasion of zebra mussels, Dreissena polymorpha, into Western Europe and North America has driven widespread ecological change. Attachment of zebra mussels to the shell of native unionoid mussels has resulted in reductions in unionoid abundance and, in extreme cases, their localised extirpations. While the impacts of zebra mussels on infested unionoids are well documented, the possible benefits of the assoc...
Fouling of European freshwater bivalves (Unionidae) by the invasive zebra musse...
Sousa, Ronaldo Gomes; Pilotto, Francesca; Aldridge, David C.1. The zebra mussel (Dreissena polymorpha) is well known for its invasive success and its ecological and economic impacts. Of particular concern has been the regional extinction of North American freshwater mussels (Order Unionoida) on whose exposed shells the zebra mussels settle. Surprisingly, relatively little attention has been given to the fouling of European unionoids. 2. We investigated interspecific pat...
