The effects of prey, habitat heterogeneity and fire on the spatial ecology of peninsular Diamond Pythons (Morelia spilota spilota: Pythonidae)

Understanding an organism's home range is an important component of effective wildlife management. However, home ranges can vary spatially and temporally within and between populations. Landscape ecology theory can provide a framework for understanding spatio-temporal variability in animal traits. We used radio-telemetry in a population of diamond python Morelia spilota spilota Lacepede (Pythonidae) from a biologically rich and structurally heterogeneous reserve in eastern Australia to explore the relationship between home range size, optimal foraging theory and vegetation mosaic theory. Twelve adult snakes were tracked between September 2004 and February 2008. Male home ranges were significantly larger (P
