We studied home range and movement patterns of the Guatemalan Beaded Lizard, Heloderma charlesbogerti, over a two-year period in a seasonally dry tropical forest of eastern Guatemala. We captured and permanently identified 32 individuals from March 2006 to March 2008, of which we radio-tracked six. Using the fixed Kernel method, the average home range size (all seasons) was 55.5 ± 73.3 ha. The average home range size was substantially larger during the wet season (94.3 ± 121 ha) than in the dry season (16.6 ± 25 ha). The surface activity was highest from June to October, and activity decreased with a decreasing amount of rainfall. Mammals constructed most of the underground shelters used by the lizards (77.08%). Shelters used during the dry season had been occupied for longer periods than those used during the wet season. The longest occupancy of an underground shelter was 62 days. The results of this study could be used for future conservation management of H. charlesbogerti and its habitat.
