Preliminary analysis of home range structure in the Komodo monitor Varanus komodoensis

We conducted a radio-telemetric study to assess home range size and structure in the Komodo monitor, Varanus komodoensis, using minimum convex polygon (MCP) and kernel statistics. Home ranges calculated by MCP varied from 278 ha to 530 ha, while areas covered by 100% kernel contours ranged from 170 ha to 390 ha. We suggest that these areas probably represent only part of the entire home range of V. komodoensis. Locations recorded during long excursions of up to 5,500 m accounted for most of the difference observed between MCP and kernel-based methods. Home ranges showed different partitioning of core areas of most intensive use, which covered up to 29.5% of kernel utilization distribution and 56% of MCPs. Our results provide preliminary data to develop comprehensive studies on space use patterns of the Komodo monitor as part of management and conservation initiatives for Komodo monitors in Komodo National Park and the island of Flores, southeast Indonesia.
