Fig. 1From: An integrative approach to phylogeography: investigating the effects of ancient seaways, climate, and historical geology on multi-locus phylogeographic boundaries of the Arboreal Salamander (Aneides lugubris) Aneides lugubris from (a) Lake Co., (b) Solano Co., (c) the Sierra Nevada Mtns., and (d) Santa Cruz Co. (Photos: Mitchell Mulks). Note the pronounced geographic variation in spotting among populations. Note also that the salamander in panel D has a head wound that likely resulted from agonistic interaction with another A. lugubris Back to article page
