Density currents driven by differential cooling in lakes: occurrence, dynamics and implications for littoral-pelagic exchange
Cross-shore flows exchange water laterally in lakes, with ecological implications for the ecosystem. One example is the convective circulation induced by differential cooling, also known as the thermal siphon. This lateral flow forms when the sloping sides ...
EPFL2022Benthic Biofilms in Glacier-Fed Streams from Scandinavia to the Himalayas Host Distinct Bacterial Communities Compared with the Streamwater
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Emmy Marie Oppliger, Virginia Tadei, Tyler Joe Kohler, Jade Brandani, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas, Martina Andrea Schön
Microbial life in glacier-fed streams (GFSs) is dominated by benthic biofilms which fulfill critical ecosystem processes. However, it remains unclear how the bacterial communities of these biofilms assemble in stream ecosystems characterized by rapid turno ...
AMER SOC MICROBIOLOGY2022Glacier loss and vegetation expansion alters organic and inorganic carbon dynamics in alpine streams
Tom Ian Battin, Nicola Deluigi, Andrew Lean Robison, Camille Aude Rolland
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the ‘greening’ of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, ...
2022Influence of Microplastics on Microbial Structure, Function, and Mechanical Properties of Stream Periphyton
Kristin Schirmer, Ahmed Tlili, Renata Behra
Periphyton is a freshwater biofilm composed of prokaryotic and eukaryotic communities that occupy rocks and sediments, forming the base of the food web and playing a key role in nutrient cycling. Given the large surface that periphyton comprises, it may al ...
FRONTIERS MEDIA SA2022Convective regimes induced by surface cooling and topography in stratified waterbodies
Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas
Gravitational convection plays a significant role in the ventilation, heat and mass distribution of aquatic systems. This study investigates thermally driven convection resulting from heat loss at the air-water interface during cooling periods in freshwate ...
Madrid2022Unconfined Plunging of a Hyperpycnal River Plume Over a Sloping Bed and Its Lateral Spreading: Laboratory Experiments and Numerical Modeling
David Andrew Barry, Ulrich Lemmin, Koen Blanckaert, Haoran Shi
Hyperpycnal (negatively buoyant) river inflow into lakes and oceans often develops three-dimensional (3D) plunging flow patterns when laterally unconfined. To determine the 3D flow pattern characteristics, laboratory experiments of laterally unconfined plu ...
2022Kleptoplast distribution, photosynthetic efficiency and sequestration mechanisms in intertidal benthic foraminifera
Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin, Michael Kühl
Foraminifera are ubiquitously distributed in marine habitats, playing a major role in marine sediment carbon sequestration and the nitrogen cycle. They exhibit a wide diversity of feeding and behavioural strategies (heterotrophy, autotrophy and mixotrophy) ...
SPRINGERNATURE2021Assessment of abundance and community composition of benthic macroinvertebrates: recommendations for improved sampling, fixation and extraction of oligochaetes
Benoît Jean Dominique Ferrari, Régis Lionel Vivien
For several decades, the abundance and community structure of benthic macroinvertebrates have been studied to assess the biological quality of aquatic ecosystems. Procedures aiming at studying the whole of macroinvertebrate communities were mainly designed ...
2020In situ eutrophication stimulates dinitrogen fixation, denitrification, and productivity in Red Sea coral reefs
Nils Rädecker, Hal Hunt Jones II
Eutrophication (i.e. the increase of [in-]organic nutrients) may affect the functioning of coral reefs, but knowledge about the effects on nitrogen (N) cycling and its relationship to productivity within benthic reef communities is scarce. Thus, we investi ...
2020Responses of reef bioindicators to recent temperature anomalies in distinct areas of the North Ari and Rasdhoo atolls (Maldives)
Arthur Adams, Aurélie Angéloz, Anaël Lehmann
Assessments of reef sediments in the North Ari Atoll (Maldives) were conducted in 2015 and 2018 on reefs of three islands with different management strategies: community, resort, and uninhabited. Indices applied were the Foraminifera in Reef Assessment and ...
