Figures 1 in Biogeographical affinities and evolution of terrestrial fauna in the Qinghai-Tibetan Plateau and the Himalayas: a case study of Aphidomorpha

Figures 1. Generalized tracks and nodes based on the global distributions of aphid species in the QTPH. Generalized tracks are indicated by colored lines, and nodes are indicated with orange dots. A generalized track is a summary of replicated distribution patterns of different taxa (species); a node is a distribution area where two or more generalized tracks intersect. Generalized tracks and nodes together indicate biogeographical affinities between aphid faunas in the QTPH and other regions.
