“…Several surveys have been carried out in temperate areas (Best & Spiegel, 1984;, 2000a, 2000bShadwick & Stephenson, 2004;Tesmer & al., 2005;Aguilar & al., 2007;Brown & Spiegel, 2008;Shadwick & al., 2009a), tropical regions (Stephenson & al., 1999;Moore & Spiegel, 2000c;Moore & Stephenson, 2003;Powers & Stephenson, 2006;Ndiritu & al., 2009), boreal regions (Spiegel & Stephenson, 2000;Moore & al., 2000;Kosheleva & al., 2009), and aquatic environments Tessmer & Schnittler, 2009). However, it is remarkable that Europe, one of the territories most extensively studied for the great majority of organisms, has barely been surveyed for protosteloid amoebae.…”
