  • Aerated pilot-scale treatment wetland to remove chemical and fecal pollution contained in combined sewer overflows
    Daniella Portela, Katharina Tondera, Vaidotas Kisielius, Jean Marc Choubert, Pedro Carvalho, Stéphane Troesch, Pascal Molle

    Treatment wetlands (TWs) have been proposed as a reliable method for removing pollutants from combined sewer overflow (CSO). However, there is a lack of studies on the performance of aerated TWs in removing micropollutants from CSO. We assessed the role of two pilot-scale TWs, one with gravel top layer and the other with sand top layer, fed with mi…

  • Differing responses of functional and taxonomic waterbird diversity to vegetation height and water level variation in a coastal wetland
    Jean Secondi, Gwendoline Percel, Céline Arzel, Aurélie Davranche, Sébastien Farau

    The conservation of wetland biodiversity is a major global issue. In anthropogenic landscapes, it requires the identification of environmental conditions and management practices that sustainably maintain the diversity of the communities. We carried out a six-year survey over 18 sites (78 ha) in the Marais Breton, lowland grazing marshes on the wes…

  • Characterization of Macroplastics in Flood Deposits along Contrasting Sections of the Saône River (France)
    Apoline Zahorka, André-Marie Dendievel, Brice Mourier

    Rivers transport macroplastics (> 1 cm), which can remain trapped in several parts of the floodplain: banks, islands, lateral channels, infrastructures, and vegetation. Residence times vary and can be up to years. This work focuses on the Saône River, a lowland river, where 19 organic flood deposits were sampled on islands and riverbanks. They are …

  • Does nocturnal light pollution impair immune function in a wild‐living amphibian?
    Louise Cheynel, Adeline Dumet, Emmanuelle Gilot‐fromont, Corinne Régis, Eve Ramery, Vanessa Gardette, Benjamin Rey, Thierry Lengagne, Nathalie Mondy

    Light pollution is among the most rapidly growing anthropogenic stressors on Earth. As it spreads far beyond its original source, it affects natural protected areas playing a key role in protecting biodiversity. While physiological impacts of light are extensively studied in laboratory animals and livestock, it is yet unknown what are the physiolog…

  • Advances, challenges and frontiers for omics in subterranean ecosystems
    Pau Balart-García, Helena Bilandžija, Iliana Bista, Mina Bizic, Matthew Campbell, Martina Cappelletti, Steven Cooper, Marjorie Couton, Jean-François Flot, Michelle Guzik, Clemens Karwautz, Tillmann Lueders, Stefano Mammola, Hans Recknagel, Sylvie Rétaux, Serban Sarbu, Mahima Tawal, Mattia Saccò
  • Effects of lateral hydrological connectivity on the taxonomic and functional structure of fish communities in Saône river floodplains (France): implications for non‐native species distribution.
    Yann Lelièvre, Emilien Gaigné, Gaël Grenouillet, Guillaume Mortreux, Jérôme Moreau, Jean‐philippe Couasné, Julien Maupoux, Sébastien Motreuil, Rémi Wattier, Maria Teixeira, François‐xavier Dechaume-Moncharmont, Loïc Bollache

    Large alluvial plain rivers provide a complex mosaic of freshwater habitats characterised by a lateral hydrological connectivity (LHC) gradient between the main channel and floodplains. This connectivity plays a key role in structuring aquatic communities, influencing species distribution, diversity, and ecosystem processes. The aims of our study w…

  • Molecular Evidence for the Placement of Microcerberidae (Crustacea: Isopoda) Within the Suborder Asellota and Invalidity of the Suborder Microcerberidea
    Christophe J Douady, Florian Malard, Nicole Coineau, Clementine Francois, Colin Issartel, Jeongho Kim, Lara Konecny‐dupré, Tristan Lefebure, Kelly L Merrin, Jessica A Thomas Thorpe

    Since their discovery, the question of the phylogenetic position of Microcerberidae within Isopoda has been widely debated. Initially perceived as close relatives of the Anthuridae, the debate has shifted towards considering them either as a sister group of Asellota or positioned within the Asellota in their own right. In this study, we used sequen…

  • Monitoring of Riverine Aquatic Vegetation Using Satellite PlanetScope Imagery: Feasibility, Limitations and Prospects
    Léo Rasse, Julien Godfroy, Géraldine Nogaro, Florian Cordier, Danaë Feldis, Sophie Meunier, Sara Puijalon, Hervé Piégay

    Spectral interference induced by the water and the spatial resolution of many satellite images (≥ 10 m) limit the efficiency of remote sensing for monitoring riverine aquatic plant stands. In this study, the potential of using PlanetScope satellite images (3 m in spatial resolution, ~daily acquisition) for monitoring seasonal and interannual aquati…

  • Microplastic impacts on soil and sediment bioturbation: insights from microcosm experiments across diverse ecosystems
    Mohammad Wazne, Franck Gilbert, Manon Vallier, Caroline Lise, Solenn Bailly, Stefan Krause, Laurent Simon, Yvan Capowiez, Florian Mermillod-Blondin, Camille Larue

    Ecosystem engineering by bioturbation shapes ecosystems by physically modifying soil and sediment habitats, affecting microbial communities and biogeochemical processes. Although bioturbation is a key process for ecosystem health and functioning, its response to contaminants like microplastics (MPs) remains poorly explored. To address this gap, we …

  • Use of Microbial Biofilms to Assess Groundwater Quality in Karstic Ecosystems
    Lina Fabre, Clémentine Francois, Félix Vallier, Maïlys Gauthier, Emmanuel Malet, Ludovic Guillard, Yves Perrette, Florian Mermillod-Blondin

    Karstic aquifers are particularly vulnerable to contaminations but, unlike surface waters, biological indicators of their groundwater quality are lacking. We propose a methodology based on microbial biofilms developed on artificial substrates (clay beads) to evaluate groundwater quality. Clay beads were incubated every 2 months over 18 months in th…
