Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming

Nils Rädecker

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 ...

Rapid grain boundary diffusion in foraminifera tests biases paleotemperature records

Anders Meibom, Jaroslaw Hubert Stolarski, Lukas Baumgartner, Arthur Adams, Deyanira Graciela Cisneros Lazaro, Jinming Guo

The paleoseawater temperature record from the oxygen isotope compositions of fossil foraminifera tests may be biased by up to about 1 degrees C due to grain-boundary diffusion alone, according to isotope exchange experiments on foraminifera tests. The oxyg ...

A method to disentangle and quantify host anabolic turnover in photosymbiotic holobionts with subcellular resolution

Anders Meibom, Arnaud Comment, Maoz Fine, Emma Mary Gibbin, Guilhem Maurice Louis Banc-Prandi

A wide range of organisms host photosynthesizing symbionts. In these animals the metabolic exchange between host and symbionts has prevented in situ host anabolic turnover to be studied without the confounding effect of translocated photosynthates. Using t ...

From the product to the process: Fine-scale skeletal structures of scleractinian corals and their relevance to biomineralization models, geochemical sampling strategies, and phylogenetic reconstructions

Anders Meibom, Jaroslaw Hubert Stolarski

Interpretation of biomineralization processes based solely on the end product - the skeleton - may seem abreakneck task. This is because the biologically controlled mineralization involves cascades of intermediatephases and the activity of a myriad of orga ...

Burial-induced oxygen-isotope re-equilibration of fossil foraminifera explains ocean paleotemperature paradoxes

Anders Meibom

Oxygen-isotope compositions of fossilised planktonic and benthic foraminifera tests are used as proxies for surface-and deep-ocean paleotemperatures, providing a continuous benthic record for the past 115 Ma. However, visually imperceptible processes can a ...

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

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon

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 ...

MALDI-MS and NanoSIMS imaging techniques to study cnidarian-dinoflagellate symbioses

Anders Meibom, Christophe Kopp

Cnidarian-dinoflagellate photosynthetic symbioses are fundamental to biologically diverse and productive coral reef ecosystems. The hallmark of this symbiotic relationship is the ability of dinoflagellate symbionts to supply their cnidarian host with a wid ...

Biomineralization in Newly Settled Recruits of the Scleractinian Coral Pocillopora damicornis

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

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 ...

Impact of farming practices on soil diatoms and testate amoebae: A pilot study in the DOK-trial at Therwil, Switzerland

Testate amoebae (Arcellinida and Euglyphida) and diatoms (Bacillariophyta) respond to different ecological gradients. These protists are useful tools for biomonitoring and paleoecological studies in aquatic and terrestrial ecosystems. However, little is kn ...

26Mg labeling of the sea urchin regenerating spine: Insights into echinoderm biomineralization process

Anders Meibom, Jaroslaw Hubert Stolarski, Christophe Kopp

This paper reports the results of the first dynamic labeling experiment with regenerating spines of sea urchins Paracentrotus lividus using the stable isotope Mg-26 and NanoSIMS high-resolution isotopic imaging, which provide a direct information about the ...
