Abstract
<p>A Community Temperature Index (CTI, y-axis) was calculated for each one of the seven habitats (x-axis) as the average Species Temperature Index (calculated after the average temperature of each species’ geographical range in Europe, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087245#pone.0087245-Devictor1" target="_blank">[13]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087245#pone.0087245-VanSwaay1" target="_blank">[14]</a>) weighted by species’ total abundance, sampled in 1998 (filled circle) and 2011 (empty circle) in each of the habitats. Figure shows significant increase of CTI in all habitats except for the agricultural areas.</p
