| Abstract |
|
The use of microhabitat and burrows of 10 free-ranging Bolson tortoise (Gopherus flavomarginatus) hatchlings was studied by radiotelemetry during the hot rainy season of 1986 and the warm dry season of 1987. Tortoises were under vegetation most ofthe time in each season (rainy season 85.3%; dry season 97.9%). Each tortoise excavated multiple burrow and pallet sites during the rainy season and moved between sites rather quickly. In contrast, each tortoise occupied only one burrow throughout the dry season. Regardless of season, tortoises preferred to'excavate or opportunistically inhabit burrows under prickly pear cactus (Opuntia rastrera).
