Hypothesis Hypothesis The entire species complex shares one glacial refugium, in the periglacial region Two species retreated to different periglacial refugia Nebria riversi, N. ingens, and the intermediate morphotype retreated to three different periglacial refugia Nebria riversi, N. ingens, and the intermediate morphotype retreated to three different periglacial refugia The glacial refugia were within drainage basins: Tuolumne + Merced, San Joaquin, King, and Kern + Kaweah The glacial refugia were within drainage basins: Tuloumne + Merced, San Joaquin, King, Kern, and Kaweah The glacial refugia were within drainage basins: Tuolumne, Merced, San Joaquin, King, Kern, and Kaweah Multiple glacial refugia persisted within the ice free areas inside the glacial extent Multiple glacial refugia persisted within the ice free areas inside the glacial extent
