Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”
Duda, Jan-Peter; Thiel, Volker
; Bauersachs, Thorsten; Mißbach, Helge; Reinhardt, Manuel; Schäfer, Nadine; Van Kranendonk, Martin J.; Reitner, Joachim
(Biogeosciences, 2018)
Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga ... -
Lias-Fossilien aus der Tongrube Eichenberg, Nordhessen
Fossilreiche Aufschlüsse im Lias des Leinetalgrabens sind eine Seltenheit. Eine Ausnahme hiervon bildet die Tongrube bei Eichenberg an der Grenze von Nordhessen zu Niedersachsen, welche etwa 20 m Ton- und Mergelschiefer ... -
Microbial fabric formation in spring mounds ("microbialites") of alkaline salt lakes in the Badain Jaran Sand Sea, PR China
The large sandy desert of Badnin Jaran Shamo, Inner Mongolia, has several salt lakes located among megadunes with crests as high as 400 m. Most of the lakes are hypo- to hypersaline and alkaline, with pH values between ... -
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia
The crater lake of the small volcanic island Satonda, Indonesia, is unique for its red-algal microbial reefs thriving in marinederived water of increased alkalinity. The lake is a potential analogue for ancient oceans ... -
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia - Reply
Our paper (Arp et al. 2003) revises previous studies of Kaz´mierczak and Kempe (1990, 1992), Kempe and Kaz´mierczak (1990a, 1990b, 1993), and Kempe et al. (1996, 1997) on Lake Satonda reefs with regard to biofilm calcification ... -
Microbialites and hydrochemistry of the crater lake of Satonda
Kempe, Stephan; Kazmierczak, Józef; Reimer, Andreas; Landmann, Guenter; Reitner, Joachim(Globale und regionale Steuerungsfaktoren biogener Sedimentation, 1996)
The Satonda crater lake is up to now the only known "marine" lake with an increased alkalinity compared to seawater. Therefore, the lake contains a decreased amount of Ca2 +. Its pH values about 8.5-8.6. The lake was ... -
Molecular Phylogeny of the Leafy Liverwort Lejeunea (Porellales): Evidence for a Neotropical Origin, Uneven Distribution of Sexual Systems and Insufficient Taxonomy
Heinrichs, Jochen; Dong, Shanshan; Schäfer-Verwimp, Alfons; Pócs, Tamás; Feldberg, Kathrin; Czumaj, Aleksandra; Schmidt, Alexander R.; Reitner, Joachim; Renner, Matt A. M.; Hentschel, Joern; Stech, Michael; Schneider, Harald (PLoS ONE, 2013-12-18)
Background: Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history and ... -
Morphologie einiger Süßwasserporifera (Baikalospongia bacillifera, Lubomirskia baicalensis, Swartschewskia papyracea) des Baikal-Sees (Sibirien, Rußland)
Während einer 9-tägigen Exkursion auf dem Baikal-See vom 2.-10. September 1993 wurden mehrere Proben der endemischer Baikal-Schwämme (Lubomirskiidae) Swartschewskia papyracea, Lubomirskia baicalensis und Baikalospongia ... -
Observations on Astraeospongium meniscum (Roemer, 1948) from the Silurian of western Tennessee; constructional morphology and palaeobiology of the Astraeospongiidae (Calcarea, Heteractinellidae)
Astraeospongium is found to form secondary calcareous basal skeletons and thus may be attributed to the morphological grouping "coralline sponges". In A. meniscum, a bowl-shaped sponge with a massive skeleton of octactins, ... -
Provenance of the Bosnian Flysch
Mikes, Tamás; Christ, Dominik; Petri, Rüdiger; Dunkl, István; Frei, Dirk; Báldi-Beke, Mária; Reitner, Joachim
; Wemmer, Klaus
; Hrvatović, Hazim; Eynatten, Hilmar (Swiss Journal of Geosciences, 2008)
Sandwiched between the Adriatic Carbonate Platform and the Dinaride Ophiolite Zone, the Bosnian Flysch forms a c. 3000 m thick, intensely folded stack of Upper Jurassic to Cretaceous mixed carbonate and siliciclastic ... -
Über Umfang und Stellung des Rhaet
Wiedmann, J.; Fabricius, F.; Krystyn, L.; Reitner, Joachim; Ulrichs, M. (Newsletters on stratigraphy, 1979)
The duration and position of the Rhaetian Stage are di scussed. With the recognition of Rhabdoceras suessi - up to now the index species of the Upper Norian (Sevatian) - in one of the Alpine type sections of the Rhaetian, ... -
Widefield deconvolution epifluorescence microscopy combined with fluorescence in situ hybridization reveals the spatial arrangement of bacteria in sponge tissue
Manz, Werner; Arp, Gernot; Schumann-Kindel, Gabriela; Szewzyk, Ulrich; Reitner, Joachim
(Journal of Microbiological Methods, 2000)
Widefield deconvolution epifluorescence microscopy (WDEM) combined with fluorescence in situ hybridization (FISH) was performed to identify and characterize single bacterial cells within sections of the mediterranean sponge ... -
Zur Eischalenstruktur von Varanus komodoensis Ouwens 1912
Die Eischalenstruktur von Varanus komodoensis OUWENS 1912 (Komodowaran) wird mit verschiedenen Methoden untersucht (REM. Dünnschliffe. histologische Methoden. Fluorochromierungen. EDAX) und dokumentiert. Sie besteht aus ... -
Zygomycetes in Vesicular Basanites from Vesteris Seamount, Greenland Basin - A New Type of Cryptoendolithic Fungi.
Ivarsson, Magnus; Peckmann, Jörn; Tehler, Anders; Broman, Curt; Bach, Wolfgang
; Behrens, Katharina; Reitner, Joachim
; Böttcher, Michael E.; Norbäck Ivarsson, Lena (PloS one, 2015)
Fungi have been recognized as a frequent colonizer of subseafloor basalt but a substantial understanding of their abundance, diversity and ecological role in this environment is still lacking. Here we report fossilized ...
