Assessing the utility of trace and rare earth elements as biosignatures in microbial iron oxyhydroxides
Heim, Christine; Simon, Klaus; Ionescu, Danny; Reimer, Andreas; De Beer, Dirk; Quéric, Nadia-Valérie; Reitner, Joachim; Thiel, Volker (Frontiers in Earth Science, 2015)Microbial iron oxyhydroxides are common deposits in natural waters, recent sediments, and mine drainage systems. Along with these minerals, trace and rare earth elements (TREE) are being accumulated within the mineralizing ... -
Frutexites-like structures formed by iron oxidizing biofilms in the continental subsurface (Äspö Hard Rock Laboratory, Sweden)
Heim, Christine; Quéric, Nadia-Valérie; Ionescu, Danny; Schäfer, Nadine; Reitner, Joachim (PLOS ONE, 2017)Stromatolitic iron-rich structures have been reported from many ancient environments and are often described as Frutexites, a cryptic microfossil. Although microbial formation of such structures is likely, a clear relation ... -
Natural variability or anthropogenically-induced variation? Insights from 15 years of multidisciplinary observations at the arctic marine LTER site HAUSGARTEN
Soltwedel, Thomas; Bauerfeind, Eduard; Bergmann, Melanie; Bracher, Astrid; Budaeva, Nataliya; Busch, Kathrin; Cherkasheva, Alexandra; Fahl, Kirsten; Grzelak, Katarzyna; Hasemann, Christiane; Jacob, Marianne; Kraft, Angelina; Lalande, Catherine; Metfies, Katja; Nöthig, Eva-Maria; Meyer, Kirstin; Quéric, Nadia-Valérie; Schewe, Ingo; Włodarska-Kowalczuk, Maria; Klages, Michael (Ecological Indicators, 2016)Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions arelargely only accessible by means of expensive modern infrastructure and instrumentation. In 1999, theAlfred Wegener ...
