The cost of adaptability: resource availability constrains functional stability under pulsed disturbances
Global change exposes ecosystems to changes in the frequency, magnitude, and concomitancy of disturbances, which impact the composition and functioning of these systems. Here, we experimentally evaluate the effects of salinity disturbances and eutrophicati ...
Washington2024At what spatial scale does natural selection operate? Using multiscale frameworks to calibrate the effects of environmental factors across landscape continuums
Patterns in nature arise from processes interacting across a continuum of spatial scales, where new relationships emerge at each level of investigation. These patterns are nested features encompassing fine-scale local patterns, such as topography and geolo ...
EPFL2024Treeline displacement may affect lake dissolved organic matter processing at high latitudes and altitudes
Climate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes in soil organic matter. Eventually, soil organic matter is transported to alpine and subarctic lakes with yet unknown consequences for dissolved ...
Nature Portfolio2024Food 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 ELSEVIER2023Use of an unmanned aerial-aquatic vehicle for acoustic sensing in freshwater ecosystems
Freshwater ecosystems are endangered, underfunded and understudied, making new methods such as passive acoustic monitoring (PAM) essential for improving the efficiency and effectiveness of data collection. However, many challenges are still to be addressed ...
Hoboken2023Looking for a democratic process to tackle sustainable development challenges – the Academic Citizens’ Assembly 2022
A democracy is simply a governance system, leading to decisions that should reach the goals of society. So what are those goals? Our collective wellbeing, today and tomorrow, depends on simultaneously satisfying all fundamental human needs and healthy ecos ...
Business School Lausanne (BSL)2022Density 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 ...
EPFL2022Stability Analysis of Submerged Vegetation Patterns in Rivers
Aquatic vegetation in fluvial systems is often characterized by spatial patterning of the plant patches. To investigate the conditions for the formation of vegetation patches, we explore the stability of a uniform flow over a non-erodible bed with a unifor ...
2022Improved framework to estimate travel time and derived distributions in hydrological control volumes
Crossing properties of soil saturation, defined as the duration and excursion of soil saturation below and above certain thresholds, are key variables to ecosystem functioning and evolution by primarily influencing the plant and soil microbes physiological ...
