Nutrient limitations induced by drought affect forage N and P differently in two permanent grasslands

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra, Claire Emilie Deléglise

Drought events can strongly affect ecosystem functioning by modifying relationship between plants, microbes and soil chemistry, with consequent impacts on nutrient cycling. However, the potential impacts of a soil moisture reduction on the nitrogen (N) and ...

From the product to the process: Fine-scale skeletal structures of scleractinian corals and their relevance to biomineralization models, geochemical sampling strategies, and phylogenetic reconstructions

Anders Meibom, Jaroslaw Hubert Stolarski

Interpretation of biomineralization processes based solely on the end product - the skeleton - may seem abreakneck task. This is because the biologically controlled mineralization involves cascades of intermediatephases and the activity of a myriad of orga ...

Dynamics and potential drivers of CO2 concentration and evasion across temporal scales in high-alpine streams

Tom Ian Battin, Asa Lovisa Viktoria Horgby, Nicolas Thomas Georges Escoffier, Luis Gómez Gener

Carbon dioxide (CO2) evasion from streams greatly contributes to global carbon fluxes. Despite this, the temporal dynamics of CO2 and its drivers remain poorly understood to date. This is particularly true for high-altitude streams. Using high-resolution t ...

Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli

François Gillet

The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environmental conditions lea ...

Fast Potentiometric CO2 Sensor for High-Resolution in Situ Measurements in Fresh Water Systems

Nadezda Pankratova, Bernhard Wehrli

We present a new potentiometric sensor principle and a calibration protocol for in situ profiling of dissolved CO2 with high temporal and spatial resolution in fresh water lakes. The sensor system is based on the measurement of EMF between two solid-contac ...

Impact of drought on the functioning of grassland systems

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

A rainfall manipulation experiment was conducted over a two-year period on two semi-natural grassland sites, in order to determine the effects of drought on both forage production (dry matter and nutritive value) and plant-soil relationships. Water stress ...

Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels

Tom Ian Battin

Phototrophic biofilms are ubiquitous in freshwater and marine environments where they are critical for biogeochemical cycling, food webs and in industrial applications. In streams, phototrophic biofilms dominate benthic microbial life and harbour an immens ...

Biogeochemical Cycling by a Low-Diversity Microbial Community in Deep Groundwater

Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Louise Julia Balmer, Guillaume Sommer, Chen Qian

Olkiluoto, an island on the south-west coast of Finland, will host a deep geological repository for the storage of spent nuclear fuel. Microbially induced corrosion from the generation of sulphide is therefore a concern as it could potentially compromise t ...

Marine and freshwater micropearls: biomineralization producing strontium-rich amorphous calcium carbonate inclusions is widespread in the genus Tetraselmis (Chlorophyta)

Michaël Bensimon, Montserrat Filella

Unicellular algae play important roles in the biogeochemical cycles of numerous elements, particularly through the biomineralization capacity of certain species (e.g., coccolithophores greatly contributing to the "organic carbon pump" of the oceans), and u ...
