Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi
Anders Meibom, Stéphane Laurent Escrig
Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...
Berlin2024Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming
Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...
London2024Coupled 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 ...
2023Photobiology and metabolic interactions in the symbiotic jellyfish Cassiopea
The symbiont-bearing jellyfish Cassiopea live a benthic lifestyle, positioning themselves upside-down on sediments in shallow waters to allow their endosymbiotic algae to photosynthesize in the sunlight. Over the last decades Cassiopea has become increasin ...
EPFL2023Metabolism 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 ...
EPFL2023Symbiotic nutrient exchange enhances the long-term survival of cassiosomes, the autonomous stinging-cell structures of Cassiopea
Anders Meibom, Cristina Martin Olmos, Nils Rädecker, Claudia Isabella Pogoreutz, Guilhem Maurice Louis Banc-Prandi, Gaëlle Delphine Toullec, Niclas Heidelberg Lyndby
Medusae of the widely distributed upside-down jellyfish Cassiopea release autonomous, mobile stinging structures. These so-called cassiosomes play a role in predator defense and prey capture, and are major contributors to “contactless” stinging incidents i ...
2023Host starvation and in hospite degradation of algal symbionts shape the heat stress response of the Cassiopea-Symbiodiniaceae symbiosis
Anders Meibom, Stéphane Laurent Escrig, Cristina Martin Olmos, Nils Rädecker, Guilhem Maurice Louis Banc-Prandi, Gaëlle Delphine Toullec
Global warming is causing large-scale disruption of cnidarian-Symbiodiniaceae symbioses fundamental to major marine ecosystems, such as coral reefs. However, the mechanisms by which heat stress perturbs these symbiotic partnerships remain poorly understood ...
2023Presence of algal symbionts affects denitrifying bacterial communities in the sea anemone Aiptasia coral model
Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz
The coral-algal symbiosis is maintained by a constant and limited nitrogen availability in the holobiont. Denitrifiers, i.e., prokaryotes reducing nitrate/nitrite to dinitrogen, could contribute to maintaining the nitrogen limitation in the coral holobiont ...
