Abstract A polygon P is called a reptile, if it can be decomposed into $$k\ge 2$$ k ≥ 2 nonoverlapping and congruent polygons similar to . We prove that cyclic quadrilateral then trapezoid. Comparing with results of Betke Osburg we find every convex rep...

Campylobacter, Arcobacter, and Helicobacter species have been isolated from many vertebrate hosts, including birds, mammals, and reptiles. Multiple studies have focused on the prevalence of these Epsilonproteobacteria genera in avian and mammalian species. However, little focus has been given to the presence within reptiles, and their potential zoonotic and pathogenic roles. In this study, occu...

Recent studies of the limbic system of tetrapods have made data available that challenge some of the long-held tenets of forebrain evolution. Using the basic principle of parsimony – that the best hypotheses concerning homologies are those requiring the fewest number of evolutionary changes – we have reevaluated comparisons of tetrapod limbic systems. Given the current data, the following point...

Comparative physiological research on reptiles has focused primarily on the understanding of mechanisms of the control of breathing as they relate to respiratory gases or temperature itself. Comparatively less research has been done on the possible link between breathing and thermoregulation. Reptiles possess remarkable thermoregulatory capabilities, making use of behavioural and physiological ...

We compiled a checklist of the amphibians and reptiles of the state of Coahuila, Mexico. The list comprises 133 species (24 amphibians, 109 reptiles), representing 27 families (9 amphibians, 18 reptiles) and 65 genera (16 amphibians, 49 reptiles). Coahuila has a high richness of lizards in the genus Sceloporus. Coahuila has relatively few state endemics, but has several regional endemics. Overl...

A large number of viruses have been described in many different reptiles. These viruses include arboviruses that primarily infect mammals or birds as well as viruses that are specific for reptiles. Interest in arboviruses infecting reptiles has mainly focused on the role reptiles may play in the epidemiology of these viruses, especially over winter. Interest in reptile specific viruses has conc...

The popularity of reptiles as pets and exhibit animals in zoologic gardens continues to increase. As long as these animals remain popular, veterinarians will be asked to field questions regarding the Salmonella in reptiles. This article will present an overview of the taxonomy of Salmonella and the virulence factors associated with these bacterial organisms, Microbiological culture is the stand...

The reptile and mammals fauna of North-East of Iran were investigated and the contraction and fragmentation of some species due to climatic changes and human activities were analyzed. The sampling was carried out in selected stations throughout the Great Khorsan. The results showed that there are approximately 71 reptiles (including 39 species of lizards, 32 snakes and one turtle) and 83 specie...
