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.
MOLECULAR DIFFERENTIATION AND DISTRIBUTION WITHIN THE SPECIES COMPLEX OF PHRYNOCEPHALUS HELIOSCOPUS (REPTILIA: AGAMIDAE)

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.

DeAgamis2: 2nd INTERNATIONAL SYMPOSIUM ON AGAMID LIZARDS
To provide a nuclear perspective on phylogenetic relationships between the revealed lineages we carried out the InterSINE-PCR analysis (for the first time for agamid lizards) using two independent primer systems. In addition we used demographic analysis of mtDNA data estimating mismatch distribution for the revealed lineages. Modern range of Ph. helios-copus-complex encompasses vast areas from Araks river valley in easternmost Turkey and southern Armenia in the west to Dzhungarian Gobi in western Mongolia in the east and from Altai territory of Russia (Kulunda) in the north to Fars province in central Iran in the south (Abadeh). We analyzed distribution data of the species complex and scrutinized locality information from 100 published literature sources and catalogues of 23 herpetological collections. Altogether 726 localities were revealed, for 627 of them we were able to identify exact geographic coordinates. After the locality information was plotted on the map, distribution of species and revealed lineages was analyzed using range modeling algorithm BIOCLIM using the software DIVA-GIS ver. 5.2.
Results of molecular survey show that at least 12 separate phylogenetic lineages (4 within Ph. per-sicus and 8 within Ph. helioscopus) within the species complex, all lineages are have high support values. Furthermore, analysis of InterSINE-PCR fingerprinting profiles confirmed deep genetic differentiation within the revealed lineages and resulted in highly congruent topology with high or
moderate support values. Spatial analysis of distribution patterns within the species complex indicated significant structuring of the range in general coinciding with the revealed distributions of mtDNA lineages. Thus, presence of two isolated lineages of Ph. helioscopus in Turkmenistan is confirmed. Lineages of Ph. persicus have different altitude preferences and are isolated with mountain barriers.
Ecological range modeling proved to be useful for comparing potentially optimal habitats of different lineages. Peripheral areas surrounding the species complex range and central Turkmenistan deserts in the middle had the lowest suitability. The area of potentially unsuitable areas in central Kazakhstan separating subspecies Ph. h. helioscopus and Ph. h. varius is not well coinciding with revealed mtDNA pattern (according to molecular data this border is located further to the east). Spatial analysis of potential habitats indicated specific ecological preferences of each of the studied lineages. However, lineages restricted to isolated mountain valleys have much better model fits and their potential habitats are almost not overlapping, whereas optimal habitats of lineages inhabiting lowland and plain territories significantly overlap.
Part of the molecular analysis was completed within the international program «Consortium for the Barcoding of Life (CBOL)».

SPATIAL DISTRIBUTION AND ABUNDANCE TRENDS OF SPOTTED TOAD-HEADED AGAMA, PHRYNOCEPHALUS GUTTATUS, IN ITS NORTHERN HABITAT IN THE VOLGA REGION

During our 1998 - 2008 field surveys in the Volgograd region and adjacent territories of the Astrakhan region and Republic Kalmykia, data on the distribution and abundance of Phrynocephalus gut-tatus (Gmelin, 1789) were collected. Now the population of Ph. guttatus in the Volgograd region is located on an isolated sandy massif on the left bank of
the Don River within the Kalach-on-Don and Gorodishche districts. The abundance indices of Ph. guttatus substantially change within the limits of the peripheral population's habitat, which is caused by the high mosaicity of microstacies, the dynamics of projection vegetation covering parameters and its character, and some other factors. E.g., in the sum-
