A dataset contains 2181 unique occurrences of 88 testate amoebae species (species, genera and families) from peatlands of the Western Siberia lowland (Tyumen region and Yamalo-Nenets Autonomous okrug). The dataset is based on field studies by Mazei Yuri, Chernyshov Viktor, Bukhkalo Sergei, Mazei Natalia performed in 2008 and 2009. Dataset contains occurrences and geographic coordinates of terrestrial testate amoebae species occurring in peatland ecosystems in a moss layers with Sphagnum species and brown mosses and lichens including Pleurozium schreberi, Dicranum spp., Polytrichum commune, Hylocomnium splendens and Cladonia spp. The data has been partly analyzed and published in the related publication (Mazei, Y., Chernyshov, V., Bukhkalo, S., Mazei, N., Creevy, A. L., & Payne, R. 2017. Exploring the diversity and ecology of testate amoebae in West Siberian peatlands. Acta Protozoologica, 56(1).)Sampling Description
Study Extent
Investigations were conducted during 2008 and 2009 summer periods in the Western Siberia lowland (Tyumen region and Yamalo-Nenets Autonomous okrug).Sampling
Material was collected at 143 sampling points. The sampling points were located in peatland ecosystems that differ in moisture regime and vegetation. Samples of either mosses or plant litter of approximately 5 cm depth and 25 cm3 volume were carefully removed and immediately placed in sealed plastic bags to avoid contamination and moisture loss.Method steps
- Samples were refrigerated at 5°C as soon as possible and kept refrigerated until preparation.
- Samples for testate amoeba analysis were prepared using a method based on wet sieving. 1 cm3 of sample was soaked in water for 24 hours, stirred, filtered at 0.5 mm, the suspension left to settle for a further 24 hours, and supernatant decanted off following Mazei and Chernyshov (2011).
- Samples were examined using light microscope and shells identified to a high taxonomic resolution at 200X and 400X magnification using an identification guide (Mazei and Tsyganov, 2006). The taxonomic scheme at the genus level is based on the revisions of Kosakyan et al. (2016) and González-Miguéns et. al. (2022).
