This study was investigated the utilization of agama lizard meat meal (Agama agama) as dietary protein source in the diets of Clarias gariepinus fingerlings (MW±SE = 33.48 g±0.13). The fingerlings were fed four Isonitrogenous and Isocaloric diets containing blends of agama lizard meal in percentages of 0 (Diet I), 10 (Diet II), 20 (Diet III) and 30% (Diet IV) respectively for 8 weeks at 5% body...

Color polymorphisms are widespread in nature and may show a high variability not only within the same population, but also among populations of the same species., Color polymorphism is a common feature among reptiles and is often linked to evolution of alternative strategies. Alternative and discrete color morphs have been reported in the common wall lizard, Podarcis muralis, which show six dif...

The present study was aimed at investigating ultrastructure of different testicular cells and their interactions through various junctional specializations during different phases of reproductive cycle in wall lizard H. flaviviridis to develop an integrated approach of cell-cell interaction in control of testicular functions. Specialized steroid synthesizing cell organelles such as smooth endop...

Our knowledge of the gene coding for amelogenin, the major enamel protein, is mainly based on mammalian sequences. Only two sequences are available in reptiles. To know whether the snake sequence is representative of the amelogenin condition in squamates, we have studied amelogenin in two scincid lizards. Lizard amelogenin possesses numerous conserved residues in the N- and C-terminal regions, ...

Mammals dominate modern terrestrial herbivore ecosystems, whereas extant herbivorous reptiles are limited in diversity and body size. The evolution of reptile herbivory and its relationship to mammalian diversification is poorly understood with respect to climate and the roles of predation pressure and competition for food resources. Here, we describe a giant fossil acrodontan lizard recovered ...

Animals maintain complex associations with a diverse microbiota living in their guts. Our understanding of the ecology of these associations is extremely limited in reptiles. Here, we report an in-depth study into the microbial ecology of gut communities in three syntopic and viviparous lizard species (two omnivores: Liolaemus parvus and Liolaemus ruibali and an herbivore: Phymaturus williamsi)...
