Figure 1 in Why may the same species have different elevational ranges at different sites in New Guinea?

Figure 1. Example of the Massenerhebung effect: variation in the elevational ceiling and floor of the Island Leaf Warbler Seicercus poliocephalus on New Guinea mountains. Note that the warbler's ceiling (upper graph) and floor (lower graph) are higher on Central Range peaks than on outlier peaks; that they tend to be higher on higher peaks (summit elevation, abscissa); that they tend to be higher on inland-facing or interior-facing outlier transects than on coast-facing outlier transects; and that they tend to be higher on outlier transects further from the coast than on outlier transects nearer the coast. Data from Table 4.
