Global emergent responses of stream microbial metabolism to glacier shrinkage
Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Nicola Deluigi, Tyler Joe Kohler, Michail Styllas
Most cryospheric ecosystems are energy limited. How their energetics will respond to climate change remains largely unknown. This is particularly true for glacier-fed streams, which interface with the cryosphere and initiate some of Earth's largest river s ...
Berlin2024Fate and effects of microplastic particles in a periphyton-grazer system
Kristin Schirmer, Ahmed Tlili, Renata Behra
In the aquatic environment, microplastic particles (MP) can accumulate in microbial communities that cover submerged substrata, i.e. in periphyton. Despite periphyton being the essential food source for grazers in the benthic zones, MP transfer from periph ...
Elsevier Sci Ltd2024Impact of substrate clogging on vertical connectivity
Giovanni De Cesare, Romain Maxime Dubuis, Robin Schroff
Connectivity between the hyporheic zone and the flow is essential for the development of benthos and the reproductive success of spawning fish. The infiltration of fine sediment leads to clogging of the riverbed, reducing porosity and vertical water exchan ...
2023Benthic 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 MICROBIOLOGY2022Kleptoplast 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) ...
SPRINGERNATURE2021Responses 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 ...
2020Heavy metals and persistent organic pollutants contamination in river, estuary, and marine sediments from Atlantic Coast of Democratic Republic of the Congo
Florian Frédéric Vincent Breider, Dominique Grandjean
The pollution assessment and the evaluation of potential risks in the Atlantic Coastal Region of the Democratic Republic of the Congo are still very limited. Consequently, the present study investigates for the first time the concentrations of heavy metals ...
Springer2020In 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 ...
2020Towards simple tools to assess functional effects of contaminants on natural microbial and invertebrate sediment communities
Surface sediments can accumulate contaminants that affect microorganisms and invertebrates and disturb benthic ecological functions. However, effects of contaminants on ecological functions supported by sediment communities are understudied. Here, we teste ...
SPRINGER HEIDELBERG2020Assessment 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 ...
