NMDS representation of Bray-Curtis dissimilarities between unique sampling events in eastern Austria. Mosquito communities are clearly differentiated from one another, and in relation to environmental parameters depicted as red isolines modelled in the ordination space defined by the first two NMDS axes, using a general additive modelling approach. Communities dominated by certain species exhibit differentiation in ordination space according to species’ environmental niches. a Temperature variability. b Sunshine duration variability. c Relative humidity variability. d Precipitation variability. e Average maximum Danube water level variability. f Distances of communities to the nearest wetland. Air temperature and precipitation patterns were not found to structure communities. Weighted average species scores are provided in blue; sites are depicted as circles (Burgenland), triangles (Lower Austria) and diamonds (Vienna), differentiated between 2014 (green fill) and 2015 (yellow fill). 3D stress 0.97
