Stages of embryos varied within clutches; less developed embryos were usually dead and the most advanced embryos were usually alive. Moloch horridus, an unrelated Australian lizard that is sometimes also referred to as "spiny lizard" References External links. Sceloporus horridus. Our measurement, made using atom interferometry, shows that the attraction between atoms and the test mass does not differ appreciably from Newtonian gravity. In regions where the weak field limit of General Relativity has been confirmed by experiment, such theories need a screening mechanism to suppress the new force. Eastern spiny lizard (Sceloporus spinosus) photographed in situ, municipality of Tula, Tamaulipas, Mexico (22 September 2003). Herpetological Monographs Sexual dimorphism in the genus Sceloporus has historically been relatively well studied; however, there is little understanding of how patterns of sexual size dimorphism might vary within species and how that might affect our ability to generalize about the evolution of sexual size-dimorphism in Sceloporus and other organisms. Abstract We studied the reproductive characteristics of the spiny lizards, Sceloporus horridus and Sceloporus spinosus (Phrynosomatidae). by partnering with organizations in the scientific, technical and medical community Book about the update knowledge of mammals from San Luis Potosí State: taxonomy, diversity, natural history, conflicts and conservation actions. Further investigations on the present parasites concerning their taxonomy, morphology, biology, and ecology are necessary. Since 1982, Herpetological Monographs has been dedicated to original research about the biology, diversity, systematics and evolution of amphibians and reptiles. and skeletal anatomy of the trunk of varanid lizards (Varanidae, Anguimorpha). AVIAN PREDATION. All Rights Reserved. Patterns of sexual size-dimorphism in species of Sceloporus in the spinosus group-formosus group clade. The maximum embryonic stage at oviposition was contrasted with RCM, egg membrane thickness, and several climatic variables (temperature and precipitation) in a phylogenetic framework. 1). JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. The specimens (N = 102) of S. horridus came from the state of Morelos and Guerrero, and individuals of S. spinosus (N = 87) came from Puebla, México. Variation observed in the maximum stage at oviposition was not related to egg membrane thickness, RCM, or clutch frequency or to environmental temperature and precipitation.
