Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals
Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N-2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont function ...
ROYAL SOC2023Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...
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 ...
2023Glacier retreat and increasing vegetation cover alter the sources and sinks of organic and inorganic carbon in alpine streams
Nicola Deluigi, Andrew Lean Robison
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the greening of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, g ...
2023Nitrogen Fixation and Hydrogen Evolution by Sterically Encumbered Mo-Nitrogenase
The substrate-reducing proteins of all nitrogenases (MoFe, VFe, and FeFe) are organized as alpha 2ss2(gamma 2) multimers with two functional halves. While their dimeric organization could afford improved structural stability of nitrogenases in vivo, previo ...
AMER CHEMICAL SOC2023Contrasting Microbiome Dynamics of Putative Denitrifying Bacteria in Two Octocoral Species Exposed to Dissolved Organic Carbon (DOC) and Warming
Nils Rädecker, Claudia Isabella Pogoreutz
Mutualistic nutrient cycling in the coral-algae symbiosis depends on limited nitrogen (N) availability for algal symbionts. Denitrifying prokaryotes capable of reducing nitrate or nitrite to dinitrogen could thus support coral holobiont functioning by limi ...
2022Glacier loss and vegetation expansion alters organic and inorganic carbon dynamics in alpine streams
Tom Ian Battin, Nicola Deluigi, Andrew Lean Robison, Camille Aude Rolland
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the ‘greening’ of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, ...
2022A roadmap to understanding diversity and function of coral reef-associated fungi
Tropical coral reefs are hotspots of marine productivity, owing to the association of reef-building corals with endosymbiotic algae and metabolically diverse bacterial communities. However, the functional importance of fungi, well-known for their contribut ...
OXFORD UNIV PRESS2022High plasticity of nitrogen fixation and denitrification of common coral reef substrates in response to nitrate availability
Nils Rädecker, Hal Hunt Jones II
Nitrogen cycling in coral reefs may be affected by nutrient availability, but knowledge about concentration-dependent thresholds that modulate dinitrogen fixation and denitrification is missing. We determined the effects of different nitrate concentrations ...
2021Nutrient pollution enhances productivity and framework dissolution in algae- but not in coral-dominated reef communities
Nils Rädecker, Hal Hunt Jones II
Ecosystem services provided by coral reefs may be susceptible to the combined effects of benthic species shifts and anthropogenic nutrient pollution, but related field studies are scarce. We thus investigated in situ how dissolved inorganic nutrient enrich ...
