Disentangling the Taxonomic History of the Widespread and Overlooked Centric Diatom Stephanodiscus makarovae and Its Transfer to Cyclostephanos
Autor: Konrad Schultz, Thomas Hübener, Mirko Dreßler, Olivier Jacques, Marcus Frank, Armin Springer, Anh Tu Van
Publikováno v: Taxonomy, Vol 1, Iss 4, Pp 425-437 (2021)
Stephanodiscus makarovae, a taxon originally described from Russia, is morphologically similar to several other taxa within Cyclostephanos, namely C. invisitatus, C. delicatus and C. tholiformis. However, it has not yet been transferred into Cycloste

Benthic Diatoms on Sheltered Coastal Soft Bottoms (Baltic Sea)—Seasonal Community Production and Respiration
Autor: Ulf Karsten, Kana Kuriyama, Thomas Hübener, Jana Woelfel
Publikováno v: Journal of Marine Science and Engineering, Vol 9, Iss 9, p 949 (2021)
Benthic diatom communities dominate sheltered shallow inner coastal waters of the atidal Southern Baltic Sea. However, their photosynthetic oxygen production and respiratory oxygen consumption is rarely evaluated. In the Baltic Sea carbon budget bent

Climate-induced changes in the trophic status of a Central European lake
Autor: Thomas HÜBENER, Bernd ZOLITSCHKA, André F. LOTTER, Holger CREMER, Dirk ENTERS, Oliver HEIRI, Emiliya KIRILOVA
Publikováno v: Journal of Limnology, Vol 68, Iss 1, Pp 71-82 (2009)
We present a case study of the development of Sacrower See, a stratified, eutrophic lake in northeastern Germany, over the past 13,000 years. Total epilimnetic phosphorus (TP) concentrations were reconstructed quantitatively using a diatom-TP transfe

Assessing P status and trophic level of two lakes by speciation of particulate phosphorus forms
Autor: Thomas HÜBENER, Manfred MICHALIK, Uwe SELIG
Publikováno v: Journal of Limnology, Vol 65, Iss 1, Pp 17-26 (2006)
Seasonal variability of dissolved and particulate P forms was investigated in two lakes in Mecklenburg-Western Pomerania (North-East Germany): the polymictic Lake Bützow and the dimictic Lake Dudinghausen. Both lakes had a different trophic status a

Holocene lake phosphorus species and primary producers reflect catchment processes in a small, temperate lake
Autor: Henning S. Jensen, Sofie P. Poulsen, Kasper Reitzel, Thomas Hübener, Suzanne McGowan, Anna Marie Klamt, Bent Vad Odgaard
Publikováno v: Klamt, A M, Poulsen, S P, Odgaard, B V, Hübener, T, McGowan, S, Jensen, H S & Reitzel, K 2021, ' Holocene lake phosphorus species and primary producers reflect catchment processes in a small, temperate lake ', Ecological Monographs, vol. 91, no. 3, e01455 . https://doi.org/10.1002/ecm.1455
This paleolimnological study aims to investigate how natural processes and anthropogenic land-use changes have affected sedimentary phosphorus (P) forms and primary producers in a small, temperate lake (Lake Fuglsø, Denmark) throughout the Holocene.

Nitrate respiration and diel migration patterns of diatoms are linked in sediments underneath a microbial mat
Autor: Hannah K. Marchant, Sten Littmann, Dirk de Beer, Dack Stuart, Elisa Merz, Gaute Lavik, Judith M. Klatt, Thomas Hübener, Sharon L. Grim, Kirk Olsen, Gregory J. Dick
Publikováno v: ENVIRONMENTAL MICROBIOLOGY
Diatoms are among the few eukaryotes known to store nitrate (NO3- ) and to use it as an electron acceptor for respiration in the absence of light and O2 . Using microscopy and 15 N stable isotope incubations, we studied the relationship between dissi

Human influence on the continental Si budget during the last 4300 years: δ30Sidiatom in varved lake sediments (Tiefer See, NE Germany)
Autor: Markus Czymzik, Daniel J. Conley, Olaf Dellwig, Patricia Roeser, Carla Nantke, Achim Brauer, Thomas Hübener, Johanna Stadmark, Patrick J. Frings
Publikováno v: Quaternary Science Reviews
The continental silicon (Si) cycle, including terrestrial and freshwater ecosystems (lakes, rivers, estuaries), acts as a filter and modulates the amount of Si transported to the oceans. In order to link the variation in the terrestrial Si cycle to a

Publikováno v: Hydrobiologia. 775:21-50
Lesser Flamingo, the flagship species of saline wetlands of Africa and India, is a specialised feeder subsisting on microscopic cyanobacteria and algae. To establish the relationship between flamingo occurrence and food algal abundance and quality, a
