Surface Topography, Bacterial Carrying Capacity, and the Prospect of Microbiome Manipulation in the Sea Anemone Coral Model Aiptasia

Anders Meibom, Gaëlle Delphine Toullec, Céline Edith Loussert-Fonta

Aiptasia is an emerging model organism to study cnidarian symbioses due to its taxonomic relatedness to other anthozoans such as stony corals and similarities of its microalgal and bacterial partners, complementing the existing Hydra (Hydrozoa) and Nematos ...

Correlation of fluorescence microscopy, electron microscopy, and NanoSIMS stable isotope imaging on a single tissue section

Anders Meibom, Quentin Thomas Jeangros, Stéphane Laurent Escrig, Arun Aby Paraecattil, Gaëlle Delphine Toullec, Céline Edith Loussert-Fonta

Correlative light and electron microscopy allows localization of specific molecules at the ultrastructural level in biological tissue but does not provide information about metabolic turnover or the distribution of labile molecules, such as micronutrients. ...

The “language” of endosymbiotic partners. “A correlative workflow combining cryo-preparation, fluorescence/electron microscopy, and NanoSIMS imaging to “listen” to the molecular and metabolic dialogue between partners in symbiotic corals”

Anders Meibom, Arun Aby Paraecattil, Gaëlle Delphine Toullec, Céline Edith Loussert-Fonta

Temperature and feeding induce tissue level changes in autotrophic and heterotrophic nutrient allocation in the coral symbiosis – A NanoSIMS study

Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Julia Marie Jeanne Yvonne Bodin, Maoz Fine, Céline Edith Loussert-Fonta

Corals access inorganic seawater nutrients through their autotrophic endosymbiotic dinoflagellates, but also capture planktonic prey through heterotrophic feeding. Correlating NanoSIMS and TEM imaging, we visualized and quantified the subcellular fate of a ...
