亚罗氏血吸虫在时间和微生境资源的利用上表现出种内差异。在1974和1975年的夏季月份，大多数成虫活动发生在清晨，而大多数幼虫活动发生在中午附近。蜥蜴的活动时间平均只有2.5天/周。由于这些动物在不同的日子和一天中的不同时间活动，保卫的领土有时在空间上重叠。Jarrovi的地带性与维持充足的食物供应密切相关；领土的时间分布可能会提高摄食效率。栖息地的差异也被注意到了。
Sceloporus jarrovi *exhibits intraspecific differences in temporal and micro- habitat resource usage. During the summer months of 1974 and 1975, most adult activity occurred in the early morning while most juvenile activity occurred near noon. Lizards were active an average of only 2.5 days/wk. Because the animals were active on different days and at various times of the day, defended territories sometimes overlapped spatially. Terri- toriality of S. jarrovi is closely tied to the maintenance of an adequate food supply; a temporal distribution of territories may increase feeding efficiency. Perch site differences were also noted.
