  • 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

  • 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…

  • Early Cretaceous termite (Insecta: Blattodea) coprolites in the southern French Alps
    Marc Philippe, Didier Bert, Jacques-Léopold Brochier, Myette Guiomar, André Nel

    After appearing at the end of the Jurassic period, termites diversified during the Early Cretaceous. This diversification had a major impact on the carbon cycle. Termite coprolites provide evidence of the ecology of these insects and how they fitted into food webs. An exceptional fossil is reported, a silicified driftwood piece containing coprolite…

  • Global change threatens the biodiversity of cold regions: current knowledge and priorities for further research
    David Renault, Luis Pertierra, Tom Vorstenbosch, Ella Z Daly, Jonas Lembrechts, Ross N. Cuthbert, Charly Géron, Phillip Joschka Haubrock, Mathieu Laparie, Peter Convey, Stefan Dullinger, Franz Essl, Michelle Greve, Torsten Nygaard Kristensen, Jan Pergl, Petr Pyšek, David M Richardson, James Speed, Michaela Vítková, Anne‐kristel Bittebiere

    Cold regions are among the most pristine areas remaining globally, hosting unique fauna and flora. Historically, these regions have often been refugia from land-use change, resource exploitation and pollution, but climate warming and biological invasions increasingly constitute profound threats. Focusing on terrestrial plant and invertebrate specie…
