Diagenetic isotope exchange in biocalcites for paleoclimate reconstruction

The oxygen isotope compositions of fossil biocalcites, such as foraminifera, bivalves, brachiopods, and belemnites have allowed for reconstructions of sea surface and deep ocean temperatures throughout the Phanerozoic and constitute the most important reco ...

Thermal Stress Interacts With Surgeonfish Feces to Increase Coral Susceptibility to Dysbiosis and Reduce Tissue Regeneration

Leïla Ezzat

Dysbiosis of coral microbiomes results from various biotic and environmental stressors, including interactions with important reef fishes which may act as vectors of opportunistic microbes via deposition of fecal material. Additionally, elevated sea surfac ...

Kleptoplast distribution, photosynthetic efficiency and sequestration mechanisms in intertidal benthic foraminifera

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin, Michael Kühl

Foraminifera are ubiquitously distributed in marine habitats, playing a major role in marine sediment carbon sequestration and the nitrogen cycle. They exhibit a wide diversity of feeding and behavioural strategies (heterotrophy, autotrophy and mixotrophy) ...

A Mini-Atlas of diatom frustule electron microscopy images at different magnifications

Joris Pierre Everaerts, Chrysanthi Papadaki

Diatom algae are active and efficient photosynthesizing single cell organisms responsible for a quarter of biomass and a quarter of oxygen release on the Earth surface. Diatoms form an enormously diverse class of microorganisms possessing stiff and strong, ...

Stream Solutes and Particulates Export Regimes: A New Framework to Optimize Their Monitoring

Camille Roland Marie Minaudo

The quantification of solute and sediment export from drainage basins is challenging. A large proportion of annual or decadal loads of most constituents is exported during relatively short periods of time, a “hot moment,” which vary between constituents an ...

Investigation of subglacial weathering under the Greenland Ice Sheet using silicon isotopes

Subglacial chemical weathering plays a key role in global silicate weathering budgets, contributing to the cycling of silicon (Si) in terrestrial and marine systems and the potential drawdown of carbon dioxide from the atmosphere. Here, we use data from tw ...

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 ...

Silaffins in Silica Biomineralization and Biomimetic Silica Precipitation

Carolin Christine Lechner

Biomineralization processes leading to complex solid structures of inorganic material in biological systems are constantly gaining attention in biotechnology and biomedical research. An outstanding example for biomineral morphogenesis is the formation of h ...

Asymmetry in Size-Segregation Rates.

Christophe Ancey, Gaël Epely Chauvin, Kasper van der Vaart

We show experimentally and by comparison with theory that during particle size-segregation in a sheared granular flow large particles rise slower in regions of many small particles and small particles sink faster in regions of many large particles. Binary ...

Human convection flow in spaces with and without ventilation: personal exposure to floor-released particles and cough-released droplets

Dusan Licina

The effects of the human convective boundary layer (CBL), room airflow patterns, and their velocities on personal exposure are examined. Two pollutants are studied which simulate particles released from the feet and generated at distances of 2 and 3 m by a ...
