Australian Plate south, is now being torn apart along the transform boundary marked by the Alpine Fault. South of New Zealand the boundary becomes a transitional transform-convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench. Extending southwest of this trench is the Macquarie Ridge. The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia. The eastern islands of
Brünig-Napf-Reuss line Brünig-Napf-Reuss line The Brünig-Napf-Reuss line forms a geographical boundary in traditional Swiss culture (""). Running from the Brünig Pass along the Napf region to the Reuss (which joins the Aare at Brugg), it partly separates western (Bernese German) and eastern (Zurich German) varieties of High Alemannic, although some places east of the line belong to the western dialect group (Schwyz, Zug). The line runs across the cantons of Lucerne and Aargau. The concept was first proposed by Richard Weiss in 1947, and it reflects the cultural situation in Switzerland as established by ethnographic field work during the early 20th century.
