Studying animal movement is one approach to elucidating aspects of species ecology and natural histories. By tracking the movements of wildlife, researchers can investigate how animals utilize resources within landscapes across space and time. Understanding resource selection has conservation implications, especially in areas where landscapes have been modified and fragmented by agricultural conversion, the building of roads and settlements, and other anthropogenic disturbances. Burmesepythons (Python bivittatus) are large, constricting snakes found throughout much of Southeast Asia. Burmese pythons are habitat generalists and have been observed using human dominated areas which in some cases may initiate human-snake conflict. This study uses a standardized framework to quantify the space use, movements and habitat selection of Burmese pythons in a patchy land use matrix. Over the course of approximately 22 months, we tracked seven Burmese pythons through various habitat types in the Sakaerat Biosphere Reserve. We used dynamic Brownian Bridge Movement Models to quantify occurrence distributions (ha) and found that Burmese pythons restricted their movement by making infrequent moves and utilizing small areas (mean = 98.97 (+-) SE 35.42 ha).
