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 ...
Washington2024Fungal community composition predicts forest carbon storage at a continental scale
Forest soils harbor hyper-diverse microbial communities which fundamentally regulate carbon and nutrient cycling across the globe. Directly testing hypotheses on how microbiome diversity is linked to forest carbon storage has been difficult, due to a lack ...
Nature Portfolio2024Combined Earth observations reveal the sequence of conditions leading to a large algal bloom in Lake Geneva
Damien Bouffard, Abolfazl Irani Rahaghi, Oscar Rodrigo Sepúlveda Steiner, Rafael Sebastian Reiss, Marco Toffolon, Frédéric Charles Soulignac
Freshwater algae exhibit complex dynamics, particularly in meso-oligotrophic lakes with sudden and dramatic increases in algal biomass following long periods of low background concentration. While the fundamental prerequisites for algal blooms, namely ligh ...
Springernature2024Metabolism of the symbiotic jellyfish Cassiopea in a changing environment
Ocean warming and other anthropogenic impacts have led to a global decline in many photosymbiotic cnidarians, most notably reef-building corals. But some species of the symbiotic and (sub-)tropical upside-down jellyfish Cassiopea are increasingly reported ...
EPFL2023Ecological and Climate Impacts of Greenlandic Glacial Outwash Plains (ECO-Plains)
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Glacial outwash plains are developing fast in the Arctic, a region which warms two to four times faster than the global average. These new landscapes are climate relevant. They can be sources and sinks of greenhouse gas fluxes and they expose large amounts ...
2023Coupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis
Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker
Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...
2023High-throughput Microfluidic Platforms for S. cerevisiae Single Cell Studies
Cells consume extra-cellular nutrients and resources to maintain cellular fitness. Extra-cellular conditions vary over time. Cellular programs encoded in genes adjust to adapt to the environments. Gene regulatory networks (GRNs) have evolved to be responsi ...
