FIGURE 1 Distribution of (lentic = 337, lotic = 181) assemblages odonates across Europe. Lentic assemblages are indicated with red circles, lotic assemblages with blue circles and the main European rivers in grey. The black outlines are country boundaries in the study region. The proportion of lotic habitats is higher in southern and central Europe. The space inside each circle represents the area for which the climate data were aggregated (a radius of ~1 km around the location of each community).
