Testate Amoebae (Protozoa) in Lakes of the Qinghai-Tibet Plateau: Biodiversity, Community Structures, and Protozoic Biosilicification in Relation to Environmental Properties and Climate Warming

“…However, these authors did not find individuals of Difflugia nana or Lagenodifflugia bryophila. Interestingly, D. nana was firstly observed in the Arctic tundra (Bobrov and Wetterich, 2012). In our study, we found D. nana in lakes of the QTP, which are located high in the mountains (above 4000 m), where temperatures are similar to the ones in Arctic regions, where the species was first observed (Bobrov and Wetterich, 2012).…”

“…E can reach values between 0 and 1 with 1 indicating complete evenness. TA size data were referred and collected from original literatures (Ogden, 1983;Meisterfeld, 2002;Bobrov and Wetterich, 2012). The mean size for each sample was determined by averaging the length/ diameter of taxa presented in the sample.…”

“…Microbial organisms (e.g., diatoms, testate amoebae, and ostracods) are abundant and sensitive to environmental changes in many ecosystems, especially in lakes. Testate amoebae (TA) are a group of microorganisms (Protozoa) characterized by an agglutinated or autogenous shell, which can be found in terrestrial and aquatic ecosystems worldwide (e.g., Bobrov and Wetterich, 2012;Booth, 2002;Ehrmann et al, 2012). Their rich diversity and functional traits, high abundance, rapid responses to environmental change, and cosmopolitan distribution have made TA widely used as bio-indicators in various habitats (Mitchell et al, 2008;Qin et al, 2011).…”
