Rapid grain boundary diffusion in foraminifera tests biases paleotemperature records

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

Cellular ultrastructure in benthic foraminifera: general observations and focus on kleptoplasts.

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Research of the past few decades has revealed a great variability of metabolisms (e.g. adaptation to different microhabitats, feeding strategies, symbiosis, survival to stressful conditions) among benthic foraminiferal species. This metabolic variety is re ...

Sequestered Chloroplasts In The Benthic Foraminifer Haynesina Germanica: Cellular Organization, Oxygen Fluxes And Potential Ecological Implications

Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Haynesina germanica is a coastal benthic foraminifer known to sequester chloroplasts from benthic pennate diatoms. This study investigates its cellular organization, as well as the oxygen consumption and production rates under dark and light conditions. Th ...

Dormant or not dormant? Benthic foraminiferal metabolism under anoxia

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Hypoxic events particularly affect benthic ecosystems on continental shelves and in coastal areas where renewal of bottom waters slow. Foraminifera living in such environments are among the most tolerant to hypoxia in the meiofauna. Some foraminifera speci ...

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

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

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 ...

The climate of Europe during the Holocene: a gridded pollen-based reconstruction and its multi-proxy evaluation

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins

We present a new gridded climate reconstruction for Europe for the last 12,000 years based on pollen data. The reconstruction is an update of Davis et al. (2003) using the same methodology, but with a greatly expanded fossil and surface-sample dataset and ...

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 ...

The European Modern Pollen Database (EMPD) project

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins, Achille Mauri

Modern pollen samples provide an invaluable research tool for helping to interpret the quaternary fossil pollen record, allowing investigation of the relationship between pollen as the proxy and the environmental parameters such as vegetation, land-use, an ...
