英文摘要	Many recommendations exist for estimating home ranges of herpetofauna, often focused on mitigating effects of sedentary behavior and autocorrelation. Authors have often applied minimum convex polygons (MCP) or kernel density estimators (KDE) due to common usage or perceived benefits in comparing studies; however, assumption violations compromise the validity of estimates and comparisons between studies. Recently developed autocorrelated kernel density estimation (AIDE) alleviates these problems, so we applied this methodology to describe space use of Sonoran Desert Tortoises (Gopherus moralkal) to identify effects of age and sex on home-range size, fidelity, and range residency, and the effect of environmental condition on space use. We identified several cases of non-range-resident behavior, with immature tortoises more likely to disperse than adults. Home-range estimates from AKDE were less biased than traditional MCP and KDE estimates. Home ranges were highly variable, but range-resident immature females had smaller multi-year home ranges than males and adult females. Annual home ranges did not differ during drought, and male range areas exceeded those of females. The magnitude of annual home-range overlap did not differ by dyad or drought condition, but pairs of gravid females were less likely to overlap than were pairs of non-gravid females, suggesting that study-site productivity and reproduction-related behaviors influence patterns of range overlap. Additional study of the use of permanent rock shelters is ill illuminate patterns of space use within and between individuals, and long-term study is needed to document survival, settlement, and contribution of dispersing tortoises to new populations, especially relative to anthropogenic habitat fragmentation.
