“…Differences in climatic conditions cause the species composition and the structure of the assemblages to vary from locality to locality, being this influence stronger than the effects of geographic distance. These results are also supported by previous studies, which, although do not deal with the influence of climatic variables on protostelid assemblages, show that there are differences in species composition when comparing areas with temperate (Best and Spiegel, 1984;Moore and Spiegel, 1995, 2000a, 2000bShadwick and Stephenson, 2004;Tesmer et al, 2005;Aguilar et al, 2007;Brown and Spiegel, 2008;Shadwick et al, 2009a), tropical (Stephenson et al, 1999;Moore and Spiegel, 2000c;Moore and Stephenson, 2003;Powers and Stephenson, 2006;Ndiritu et al, 2009), and boreal climates (Moore et al, 2000;Spiegel and Stephenson, 2000;Kosheleva et al, 2009).…”
