• Abundance, size distribution and bacterial colonization of exopolymer particles in Antarctic sea ice (Bellingshausen Sea) (2004, neutral): “However, the elevated amount of larger EP particles can also be attributed to other characteristics in the sea ice and under-ice habitat, e.g. grazing or dissaggregation of larger EP or disruption of sympagic biofilms, an occurrence that has been proposed by Thomas & Dieckmann (2002).”
• Mixotrophy : a widespread and important ecological strategy for planktonic and sea-ice nanoflagellates in the Ross Sea, Antarctica (2009, neutral): “Sea ice algae are physiologically adapted to living at low light (Thomas & Dieckmann 2002), and may employ heterotrophic uptake of dissolved organics or phagotophy during periods of very low light (Palmisano & Garrison 1993).”
• Cold Tolerance in Cyanobacteria and Life in the Cryosphere (2007, neutral): “This process is well known in sea ice where the freeze-concentrated brines within channels between the ice crystals may achieve salinity values many times that of sea water (Thomas and Dieckmann, 2002).”
• Bacterial Activity at −2 to −20°C in Arctic Wintertime Sea Ice (2004, positive): “Future work will need to establish to what extent microbial activity is constrained by a decrease in water activity and an increase in ionic strength in the host solution compared to low-temperature effects on membrane and transport processes (49).”
• Life strategy, ecophysiology and ecology of seaweeds in polar waters (2007, neutral): “This imino acid is the most important osmolyte in ice-algae too (Thomas and Dieckmann 2002).”
• A fundamental dichotomy in long-chain polyunsaturated fatty acid abundance between and within marine and terrestrial ecosystems (2017, positive): “For this reason, having elevated n-3 LC-PUFA levels may be a mechanism used to survive in polar regions, where organisms typically live at temperatures near the freezing point for much of the year (Thomas and Dieckmann 2002).”
• Resistance of Microorganisms to Extreme Environmental Conditions and Its Contribution to Astrobiology (2010, neutral): “Also, living systems may live within the ice layer, as microbes do on Earth [129-131].”
• Large scale importance of sea ice biology in the Southern Ocean (2004, neutral): “…irradiance, and the growth status of bacteria and algae greatly influence their biochemical composition and those inhabiting sea ice evidently have a carbon metabolism that is different from algae from less physiologically demanding environments (Thomas & Dieckmann 2002a and citations therein).”
• Vertical distribution of exopolymer particles in sea ice of the Fram Strait (Arctic) during autumn (2003, neutral): “The occurrence of sympagic biofilms has been suggested by Thomas & Dieckmann (2002).”
• Earth's Icy Biosphere (2004, neutral): “Habitats in polar ice may serve as a model for life on Mars (Priscu et al. 1998; Priscu et al. 1999a,b; Paerl and Priscu 1998; Thomas and Dieckmann 2002) as it cooled and may assist us in our search for extinct or extant life on Mars today.”
• A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA (2010, neutral): “Although sea-ice plays a key structural role in forcing the ecology of the Ross Sea (Thomas and Dieckmann, 2002; Arrigo and Thomas, 2004), epontic algae are estimated to produce only 3.”
• PHOTOSYNTHESIS AND COLD ACCLIMATION: MOLECULAR EVIDENCE FROM A POLAR DIATOM 1 (2004, positive): “In vivo quantum yield of photosynthesis at PSII (Fv/Fm) was determine using a Xenon-PAM Fluorometer (Walz, Effeltwich, Germany) equipped with a stirrer and a cooling device, whereas reoxidation measurements were performed with a dual-modulation LED Kinetic Fluorometer (Trtilek et al. 1997).”
