Investigation of microbial community dynamics in soil during variable hydrological forcing
Climate change is expected to alter the temporal distribution of precipitation events, leading to prolonged drought periods and an increased frequency of extreme precipitation events. Changes in precipitation pattern will directly affect soil moisture dyna ...
EPFL2024Food web structure and energy flux dynamics, but not taxonomic richness, influence microbial ecosystem functions in a Sphagnum-dominated peatland
Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey
Soil microbial communities are vital for multiple ecosystem processes and services. In particular, soil microbial food webs are key determinants of soil biodiversity, functioning and stability. Unclear, however, is how struc-tural features of food webs, su ...
ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER2023Mercury isotope evidence for Arctic summertime re-emission of mercury from the cryosphere
Jakob Boyd Pernov, Jenny Thomas
During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0), which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak that is thought to resultmostly fromterrestrial Hg inputs to the ArcticOcean, fo ...
2022Genomic and metabolic adaptations of biofilms to ecological windows of opportunity in glacier-fed streams
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Tyler Joe Kohler, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas, Martina Andrea Schön
In glacier-fed streams, ecological windows of opportunity allow complex microbial biofilms to develop and transiently form the basis of the food web, thereby controlling key ecosystem processes. Using metagenome-assembled genomes, we unravel strategies tha ...
Springer2022Soil-Structure Interaction effects on the seismic behavior of steel moment resisting frames: Preliminary assessment
The purpose of this paper is to assess the influence of soil-structure interaction and site effects on the seismic behavior of steel moment-resisting frames, with a view to describing the underlying “physics” behind the damage mechanisms triggered. We exam ...
European Earthquake Engineering Association2022Influence 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 SA202221 000 birds in 4.5 h: efficient large‐scale seabird detection with machine learning
Devis Tuia, Benjamin Alexander Kellenberger
We address the task of automatically detecting and counting seabirds in unmanned aerial vehicle (UAV) imagery using deep convolutional neural networks (CNNs). Our study area, the coast of West Africa, harbours significant breeding colonies of terns and gul ...
2021Soil-structure interaction of surface footings
Lyesse Laloui, Cristiano Garbellini
Limit-state analysis of soil-structure interacting systems is a classical problem in theoretical and applied soil mechanics. Usually, the capacities of both components are evaluated separately. However, it is well known that soil-structure interaction play ...
2021Predicting spatial patterns of soil bacteria under current and future environmental conditions
Nicolas Jean Philippe Guex, Jan Roelof van der Meer, Marco Pagni, Aline Buri
Soil bacteria are largely missing from future biodiversity assessments hindering comprehensive forecasts of ecosystem changes. Soil bacterial communities are expected to be more strongly driven by pH and less by other edaphic and climatic factors. Thus, al ...
2021Increasing carbon-to-phosphorus ratio (C:P) from seston as a prime indicator for the initiation of lake reoligotrophication.
Decline in total phosphorus (TP) during lake reoligotrophication does not apparently immediately influence carbon assimilation or deep-water oxygen levels. Traditional monitoring and interpretation do not typically consider the amount of organic carbon exp ...
