“…This distribution of testate amoebae along the oligotrophic-eutrophic gradient has also been observed in aquatic ecosystems (e.g. Beyens et al, 1986;Qin et al, 2009;Ju et al, 2014). The observed trophic gradient does not affect surface vegetation though, as proxies for moisture (WTD, MC) controlled their distribution.…”

Abstract. Forty different sites, represented by 1483 samples, ranging from Alaska eastwards to Siberia, have been studied to assess the circumpolar testate amoebae species diversity. A total of 378 species have been recorded. The most common taxa are cosmopolitan and are widely distributed across various arctic habitats. Statistical analysis of testate amoebae species at sites across the Arctic have yielded geographic clusters of sampling sites that have been matched with climatic regions in the Arctic. We put forward the hypothesis that the differences in testate amoebae diversity across the Arctic hint to the existence of protozoological arctic regions. The problems concerning the question of the origin of the testate amoebae in the Arctic are also discussed, with emphasis on two arctic flagship species.

“…Studies on the ecology of lake and river testate amoebae have shown that they respond to the trophic status, pH, and pollution (Beyens et al 1986;Burbidge and Schröder-Adams 1998;Dalby et al 2000;Kumar and Patterson 2000;Moraczewski 1962;Ruzicka 1982;Schönborn 1965aSchönborn , 1966Schönborn , 1973Schönborn et al 1965). Testate amoebae communities may also respond to large scale changes in land use such as deforestation and subsequent watershed management such as fertilizer and pesticide use Scott and Medioli 1983).…”

Testate amoebae are an abundant and diverse polyphyletic group of shelled protozoa living in aquatic to moist habitats ranging from estuaries to lakes, rivers, wetlands, soils, litter, and moss habitats. Owing to the preservation of shells in sediments, testate amoebae are useful proxy indicators complementary to long-established indicators such as pollen and spores or macrofossils. Their primary use to date has been for inferring past moisture conditions and climate in ombrotrophic peatlands and, to a lesser extent, to infer pH in peatlands and the trophic or nutrient status of lakes. Recent research on these organisms suggests other possible uses in paleoecology and ecology such as sea-level reconstruction in estuarine environments, as indicators of soil or air pollution, and monitoring recovery of peatland. We review the past and present use of testate amoebae, the challenges in current research, and provide some ideas on future research directions.
