Contrasting 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 ...
2022A modern scleractinian coral with a two-component calcite–aragonite skeleton
Anders Meibom, Jaroslaw Hubert Stolarski
One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...
2020Responses of reef bioindicators to recent temperature anomalies in distinct areas of the North Ari and Rasdhoo atolls (Maldives)
Arthur Adams, Aurélie Angéloz, Anaël Lehmann
Assessments of reef sediments in the North Ari Atoll (Maldives) were conducted in 2015 and 2018 on reefs of three islands with different management strategies: community, resort, and uninhabited. Indices applied were the Foraminifera in Reef Assessment and ...
2020The modern analogue of a Cretaceous coral with a calcitic skeleton
Anders Meibom, Jaroslaw Hubert Stolarski
It was argued that, in contrast to all known modern scleractinian corals that form aragonite skeletons, the original mineralogy of the Cretaceous "Coelosmilia" (ca. 70-65 Ma) was calcite during a period when the Mg2+/Ca2+ ratio of the seawater was presumab ...
2019Vertical changes of the Co and Mn speciation along a lateritic regolith developed on peridotites (New Caledonia)
Gabrielle Dublet, Vincent Noel
Because they can host significant amounts of Co, the Mn-oxides are commonly considered as the major Co-bearing mineral species in lateritic environments. However, little is known about the process leading to the formation and/or the weathering of these Co- ...
Pergamon-Elsevier Science Ltd2017Unusual Micrometric Calcite–Aragonite Interface in the Abalone Shell Haliotis (Mollusca, Gastropoda)
Species of Haliotis ~abalone! show high variety in structure and mineralogy of the shell. One of the European species ~Haliotis tuberculata! in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Cambridge University Press2014Unusual Micrometric Calcite- Aragonite Interface in the Abalone Shell Haliotis similar to Mollusca, Gastropoda!
Species of Haliotis (abalone) show high variety in structure and mineralogy of the shell. One of the European species (Haliotis tuberculata) in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Cambridge Univ Press2014A Cretaceous scleractinian coral with a calcitic skeleton
Anders Meibom, Jaroslaw Hubert Stolarski
It has been generally thought that scleractinian corals form purely aragonitic skeletons. We show that a well-preserved fossil coral, Coelosmilia sp. from the Upper Cretaceous (about 70 million years ago), has preserved skeletal structural features identic ...
2007Landscape evolution in tidal embayments: Modeling the interplay of erosion, sedimentation, and vegetation dynamics
We propose an ecomorphodynamic model which conceptualizes the chief land-forming processes operating on the intertwined, long-term evolution of marsh platforms and embedded tidal networks. The rapid network incision (previously addressed by the authors) is ...
2007Melting experiments of a chondritic meteorite between 16 and 25 GPa: Implication for Na/K fractionation in a primitive chondritic Earth's mantle
Melting experiments at high-pressure and temperature were conducted at pressures from 16 to 25 GPa using chondritic starting material but with slightly enhanced Na- and K-contents while keeping the chondritic Na/K ratio constant. The experiments revealed t ...
