Preferred body temperature of Starred Agama Laudakia stellio collected from Western Coastal Desert of Egypt was monitored telemetrically in a temperature gradient. This species was found to be a good thermo regulator lizard. Behavior played the major role for body temperature regulation. Shuttling behavior between the hot and cold sides of the temperature gradient and voluntary hypothermia were found to be the main means of body temperature regulation. The mean selected body temperature was 35.9°C, 37.7°C at day and 32.9°C, 37.2°C at night in males and females respectively. Circadian rhythm was investigated under different light re-
gime. At LD this species showed a well defined cir-cadian rhythm with high selected body temperature during photophase and low value during scotophase. Under LL and DD the amplitude of the body temperature rhythm was greatly reduced. It was found that Laudakia stellio selected lower body temperature at night in spite of the availability of a wide range of temperatures in the temperature gradient which may prolong potential foraging time the following day.
Key words: preferred body temperature, Starred Agama, Laudakia stellio, circadian rhythm, Egypt.
HOW TO IDENTIFY SPECIMENS OF UROMASTYX LIZARDS WITHOUT MARKING

Microchipping and other marking are always a bit risk procedures for animals, namely for endangered species. A set of photographs was created to identify confiscated Uromastyx specimens which we-
re illegally imported from Morocco. A determination of subspecies was important for possible breeding.
Key words: Uromastyx lizards, marking, photography identification.

Phylogenetic inference was based on the Cytochrome c-oxidase (COI) and 16S rRNA gene; analysis of 2 mtDNA fragments (1st subunit of the 1156 bp in total) for 86 samples from 59 localities.
