Fig. 1From: The patterns of co-occurrence variation are explained by the low dependence of bark beetles (Coleoptera: Scolytinae and Platypodinae) on hosts along altitude gradientsThe space of a host can be subdivided into separate sections, each depending on the presence of particular symbionts (1 and 2) with distinct optimum performance along the respective niche axes (i.e., the elevation niche). Left panel A is re-sketched from the Fig. 1 of Rolshausen et al. (2020). Right panel B illustrates the niche overlap difference among different taxon across the same environmental elevation gradientsBack to article page
