Using NanoSIMS coupled with microfluidics to visualize the early stages of coral infection by Vibrio coralliilyticus

Anders Meibom, Isabelle Domart-Coulon, Emma Mary Gibbin

Background: Global warming has triggered an increase in the prevalence and severity of coral disease, yet little is known about coral/pathogen interactions in the early stages of infection. The point of entry of the pathogen and the route that they take on ...

Cell proliferation and migration during early development of a symbiotic scleractinian coral

Anders Meibom, Agathe Eliette Marie Lecointe, Isabelle Domart-Coulon

In scleractinian reef-building corals, patterns of cell self-renewal, migration and death remain virtually unknown, limiting our understanding of cellular mechanisms underlying initiation of calcification, and ontogenesis of the endosymbiotic dinoflagellat ...

A unique coral biomineralization pattern has resisted 40 million years of major ocean chemistry change

Anders Meibom, Isabelle Domart-Coulon, Jaroslaw Hubert Stolarski

Today coral reefs are threatened by changes to seawater conditions associated with rapid anthropogenic global climate change. Yet, since the Cenozoic, these organisms have experienced major fluctuations in atmospheric CO2 levels (from greenhouse conditions ...

Evidence for Rhythmicity Pacemaker in the Calcification Process of Scleractinian Coral

Anders Meibom, Isabelle Domart-Coulon, Jaroslaw Hubert Stolarski

Reef-building scleractinian (stony) corals are among the most efficient bio-mineralizing organisms in nature. The calcification rate of scleractinian corals oscillates under ambient light conditions, with a cyclic, diurnal pattern. A fundamental question i ...

Subcellular Investigation of Photosynthesis-Driven Carbon and Nitrogen Assimilation and utilization in the Symbiotic Reef Coral: Pocillopora damicornis

Anders Meibom, Stéphane Laurent Escrig, Christophe Kopp, Isabelle Domart-Coulon

UNLABELLED: Reef-building corals form essential, mutualistic endosymbiotic associations with photosynthetic Symbiodinium dinoflagellates, providing their animal host partner with photosynthetically derived nutrients that allow the coral to thrive in oligot ...

American Society for Microbiology2015

A nanoscale secondary ion mass spectrometry study of dinoflagellate functional diversity in reef-building corals

Anders Meibom, Isabelle Domart-Coulon

Nutritional interactions between corals and symbiotic dinoflagellate algae lie at the heart of the structural foundation of coral reefs. Whilst the genetic diversity of Symbiodinium has attracted particular interest because of its contribution to the sensi ...

Wiley-Blackwell2015

Biomineralization in Newly Settled Recruits of the Scleractinian Coral Pocillopora damicornis

Anders Meibom, Melany Melissa Gilis, Isabelle Domart-Coulon, Jaroslaw Hubert Stolarski

Calcium carbonate biomineralization of scleractinian coral recruits is fundamental to the construction of reefs and their survival under stress from global and local environmental change. Establishing a baseline for how normal, healthy coral recruits initi ...

Simultaneous extension of both basic microstructural components in scleractinian coral skeleton during night and daytime, visualized by in situ Sr-86 pulse labeling

Anders Meibom, Isabelle Domart-Coulon, Jaroslaw Hubert Stolarski

Using in situ (12 h) pulse-labeling of scleractinian coral aragonitic skeleton with stable 86Sr isotope, the diel pattern of skeletal extension was investigated in the massive Porites lobata species, grown at 5 m depth in the Gulf of Eilat Several microstr ...

Highly Dynamic Cellular-Level Response of Symbiotic Coral to a Sudden Increase in Environmental Nitrogen

Duncan Thomas Lindsay Alexander, Anders Meibom, Christophe Kopp, Isabelle Domart-Coulon

Metabolic interactions with endosymbiotic photosynthetic dinoflagellate Symbiodinium spp. are fundamental to reef-building corals (Scleractinia) thriving in nutrient-poor tropical seas. Yet, detailed understanding at the single-cell level of nutrient assim ...

American Society for Microbiology2013

Scleractinian coral cell proliferation is reduced in primary culture of suspended multicellular aggregates compared to polyps

Shirit Cohen, Anders Meibom, Agathe Eliette Marie Lecointe, Stéphanie Kéren Cohen, Isabelle Domart-Coulon

Cell cultures from reef-building scleractinian corals are being developed to study the response of these ecologically important organisms to environmental stress and diseases. Despite the importance of cell division to support propagation, cell proliferati ...

Skeletal growth dynamics linked to trace-element composition in the scleractinian coral Pocillopora damicornis

Anders Meibom, Christophe Kopp, Isabelle Domart-Coulon, Jaroslaw Hubert Stolarski

The micro-and ultra-structural skeletal growth dynamics of the scleractinian coral Pocillopora damicornis (Linnaeus 1758) was studied with pulsed Sr-86-labeling and high spatial resolution NanoSIMS isotopic imaging. Average extension rates for the two basi ...
