A second
agamid species, the Eastern Bearded Dragon Pogona barbata disappeared from the St George area in the early 1990s.
2F) is one of the most widely distributed
agamid lizards throughout the wet zone of Sri Lanka, its oviposition behavior has not been documented before.
We established a successful psychophysical procedure to test the motion sensitivity to salient stimuli in one
agamid species, the Jacky dragon, where movement is a critical component of social communication as well as interpreting important ecological information (Woo et al., in review).
The
agamid lizard Agama agama has been reported to serve as transport and reservoir host to several protozoan and helminth parasites (Wekhe and Olayinka 1999).
Age-determination in the tropical
agamid garden lizard, Calotes versicolor (Daudin), based on bone histology.
In Asia, this life form is represented by the
agamid lizards (family Agamidae); in North and South America, it is represented by the iguanid lizards (Iguanidae).
Laboratory studies of sprinting in the
agamid lizard Stellio stellio (Huey and Hertz 1982) have shown that they typically reach top speeds (95% of maximum) within about 40 cm, which is the upper distance limit of single runs during feeding in anoles.
In iguanid and
agamid lizards, which typically do rely on interlocking for prey prehension, the area of the tongue (Schwenk, 1985) that contacts the prey is characterized by large numbers of plumose papillae (Herrel et al, 1998; Delheusy et al, 1994; Schwenk, 2000).

agamid lizard with temperature-dependent sex determination.
Correlates of active body temperatures and microhabitat occupation in nine species of central Australian
agamid lizards.
The
agamid genus Calotes is one of the most widespread lizard genera in South and Southeast Asia and is distributed from Iran to the Indo-Australian Archipelago.
The extent of green coloration in male sand lizards (Lacerta agilis) seems to be indicative of fighting ability (olsson, 1994), as does the throat color of male tree lizards (Urosaurus ornatus; Thompson and Moore, 1991) and size of chest patches in
agamid lizards (Ctenophorus decresii; Osborne, 2005).
Among the lizard families best adapted to life in the desert are the
agamid lizards (family Agamidae), which occur only in the Old World (Asia and Africa) and in Australia.
Huey and Hertz (1984) measured sprint speed of
agamid lizards at seven temperatures spanning the range of conditions experienced in the field and found no evidence of performance trade-offs.
