Biogeographic differentiation between two morphotypes of the Southern Ocean diatom Fragilariopsis kerguelensis

Autor: Oliver Esper, Michael Kloster, Bank Beszteri, Barbara Glemser, Gerhard Kauer, Sarah Lena Eggers

Publikováno v: Polar Biology. 42:1369-1376

Fragilariopsiskerguelensis (O’ Meara) Hust. is a ubiquitous diatom of the Southern Ocean. Its thick frustules are the numerically dominant component of the siliceous sediment layer covering large parts of the seafloor beneath. Morphometric variabil

Semiautomated methods for microscopic image acquisition, image analysis, and taxonomic identification have repeatedly received attention in diatom analysis. Less well studied is the question whether and how such methods might prove useful for clarify

Publikováno v: Trees. 31:1683-1695

The use of cell-size parameters from oak trees as a powerful proxy for past climate reconstruction needs to be more intensively studied. The freeware tool CATS will help pushing these high-volume cell-size measurements. In this study, we analyzed the

Temporal changes in size distributions of the Southern Ocean diatom Fragilariopsis kerguelensis through high-throughput microscopy of sediment trap samples

Autor: Thomas W. Trull, Michael Kloster, Bank Beszteri, Leanne K. Armand, Andrés S. Rigual-Hernández, Gerhard Kauer

Some aspects of the life cycle of the Southern Ocean diatom Fragilariopsis kerguelensis have been investigated previously, but many of its details have not been surveyed in nature. We investigated ...

Toxicology in Vitro, Elsevier, 2018, 52, pp.106-115. ⟨10.1016/j.tiv.2018.06.002⟩

Human neural progenitor cells cultured as neurospheres are a promising tool for developmental neurotoxicity testing in vitro. In order to obtain a human cell-based tissue culture system as close to the organ as possible, it is desirable to improve th

Morphometry of the diatom Fragilariopsis kerguelensis from Southern Ocean sediment : High-throughput measurements show second morphotype occurring during glacials

Autor: Michael Kloster, Gerhard Kauer, Oliver Esper, Bank Beszteri, Nike Fuchs

Publikováno v: EPIC3Marine Micropaleontology, ELSEVIER SCIENCE BV, 143, pp. 70-79, ISSN: 0377-8398

Fragilariopsis kerguelensis is one of the most abundant diatoms in the sediments of the Southern Ocean. Its morphometric features have been proposed as proxies, based on links with, for example, iron availability, sea surface temperature and glacial/

EPIC3Applied Sciences, MDPI, 7(4), pp. 330-330, ISSN: 2076-3417

Light microscopy analysis of diatom frustules is widely used in basic and applied research, notably taxonomy, morphometrics, water quality monitoring and paleo-environmental studies. Although there is a need for automation in these applications, vari
