Over 100-Year Preservation and Temporal Fluctuations of Cell Wall Polysaccharides in Marine Sediments Open
Polysaccharides constitute an important carbon pool in marine systems, but much is still unknown about the fate and degradation of these compounds. They are derived partly from production in situ , and in coastal areas, they are partly ter…

Linking biological and geological data on dinoflagellates using the genus<i>Spiniferites</i>as an example: the implications of species concepts, taxonomy and dual nomenclature Open
Dinoflagellates encompass two taxonomic systems (dual taxonomy) reflected by separate traditions of nomenclature: one based mainly on living motile stages, and the other mainly on fossil cysts (dual nomenclature). Modern cysts may therefor…

The dinoflagellate cyst genera<i>Achomosphaera</i>Evitt 1963 and<i>Spiniferites</i>Mantell 1850 in Pliocene to modern sediments: a summary of round table discussions Open
We present a summary of two round-table discussions held during two subsequent workshops in Montreal (Canada) on 16 April 2014 and Ostend (Belgium) on 8 July 2015. Five species of the genus Achomosphaera Evitt 1963 and 33 of the genus Spin…

Differences in the optical properties of valve and girdle band in a centric diatom Open
Diatoms are phototrophic single-celled microalgae encased in a cell wall (frustule) made of amorphous silicate. The frustule comprises two valves connected by a variable number of girdle bands, all exhibiting periodic micro/nanoporous stru…

Spring Succession and Vertical Export of Diatoms and IP25 in a Seasonally Ice-Covered High Arctic Fjord Open
The biomarker IP25 and fossil diatom assemblages preserved in seafloor sediments are commonly used as proxies for paleo Arctic sea-ice reconstructions, but how their production varies over the seasons and is exported to the sediment remain…

Structure‐based optics of centric diatom frustules: modulation of the <i>in vivo</i> light field for efficient diatom photosynthesis Open
Summary The optical properties of diatom silicate frustules inspire photonics and nanotechnology research. Whether light interaction with the nano‐structure of the frustule also affects diatom photosynthesis has remained unclear due to lac…

Time capsules in natural sediment archives—Tracking phytoplankton population genetic diversity and adaptation over multidecadal timescales in the face of environmental change Open
Undisturbed records of resting stages produced in the past and stored in coastal sediments are very valuable to science, because they may provide unique insights into past evolutionary and ecological trajectories. Within marine phytoplankt…
