The effect of temperature on digestive efficiency in the herbivorous lizard Dipsosaurus dorsalis
. Journal of Comparative Physiology, 118: 1-6.
Second, during transects we also regularly encountered desert iguanas (Dipsosaurus dorsalis
) which occasionally scavenge carrion (Norris, 1953).
Risk factors affecting escape behaviour in the desert iguana, Dipsosaurus dorsalis
: speed and directness of predator approach, degree of cover, direction of turning by a predator, and temperature.
lutzae is, in general, more similar to the one observed in the lizards described by Irschick and Jayne (1999), particularly, Dipsosaurus dorsalis
and Callisaurus draconoides.

Muth (unpublished data cited in Porter and Tracy ) came to a similar conclusion when Dipsosaurus dorsalis
, a sympatric, herbivorous lizard also in Iguanidae, raised in the laboratory, reached size of sexual maturity and produced viable offspring in 7 mo, vs.
Milestead (1970) reported greater home range overlap in areas of high population density than in areas of low density in Sceloporus merriami, and Krekorian (1976) has shown a presumably temporary switch to hierarchical behavior in the otherwise territorial Dipsosaurus dorsalis
following catastrophic declines in food availability.
Muth (1980) found similar results in incubation of Dipsosaurus dorsalis
