Fossil testate amoeba assemblages have been used to reconstruct peatland palaeohydrology for more than two decades. While transfer function training sets are typically of local-to regional-scale in extent, combining those data to cover broad ecohydrological gradients, from the regional-to continental- and hemispheric-scales, is useful to assess if ecological optima of species vary geographically...

Migrants’ new transnational habitus: rethinking migration through a cosmopolitan lens in the digital age

Nedelcu, Mihaela

In: Journal of Ethnic and Migration Studies, 2012, vol. 38, no. 9, p. 1339-1356

This article puts forward a cosmopolitan reading of international migration, focusing on the role played by ICTs in generating new ways of living together and acting transnationally in the digital era. After underlining some of the complex dimensions of the transnational debate and the limits of methodological nationalism, I will argue that revisiting the national–transnational nexus by...

Diversity and biogeography of testate amoebae

Smith, Humphrey Graham ; Bobrov, Anatoly ; Lara, Enrique

In: Journal of Experimental Botany, 2008, vol. 17, no. 2, p. 329-343

Testate amoebae are amoeboid protists inhabiting a test (shell). They occur globally in soils, wetlands and freshwater, especially peats and mosses. They are of ancient origin, dating from at least the Mesozoic, with possible ancestors as old as the Neoproterozoic. Approximately 2,000 taxa have been described—a number which could easily rise to 4,000 with comprehensive recording. Whilst many...
