Fig. 8 in Ecological patterns strongly impact the biogeography of western Palaearctic longhorn beetles (Coleoptera: Cerambycoidea)

Fig. 8 Synthesis of assumed glacial refugia, dispersal barriers, filters and dispersal routes of longhorn beetles based on the analysis of regional species assemblages. R refugia of major importance, r refugia of minor importance, continuous red lines old dispersal barriers (more ancient than Postglacial), broken red lines postglacial dispersal barriers, dotted red lines postglacial filters, dotted blue arrows mostly ancient spreads, dashed blue arrows mostly recent spreads but including events before the postglacial and continuous blue arrows postglacial spreads
