| vigilance against predators induced by eavesdropping on heterospecific alarm calls in a non-vocal lizard oplurus cuvieri cuvieri (reptilia: iguania). | prey animals can reduce their risk of predation by detecting potential predators before encounters occur. some animals gain information about nearby predators by eavesdropping on heterospecific alarm calls. despite having well-developed ears, most lizards do not use vocal information for intraspecific communication, and few studies have shown practical use of the ears in wild lizards. here, we show that the madagascan spiny-tailed iguana (oplurus cuvieri cuvieri) obtains auditory signals for pre ... | 2010 | 20031993 |
| [comparative immunochemical study of the serum proteins of lacertilia (reptilia)]. | the immunochemical relationships of the serum proteins of uromastix acanthinurus, agama mutabilis, oplurus cuvieri, o. quadrimaculatus, chamaeleo chamaeleon, chalcides ocellatus and lacerta lepida were studied by means of immunoelectrophoresis with an antiserum anti-uromastix successively absorbed. homogeneity of the iguania species was pointed out and they were found more closely related to the scincid chalcides ocellatus than to the lacertid lacerta lepida. within the iguania, the two agamids ... | 1978 | 116608 |
| defining spatial and temporal patterns of phylogeographic structure in madagascar's iguanid lizards (genus oplurus). | understanding the remarkably high species diversity and levels of endemism found among madagascar's flora and fauna has been the focus of many studies. one hypothesis that has received much attention proposes that quaternary climate fluctuations spurred diversification. while spatial patterns of distribution and phylogenetic relationships can provide support for biogeographic predictions, temporal estimates of divergence are required to determine the fit of these geospatial patterns to climatic ... | 2012 | 22694729 |
| integrating field surveys and remote sensing data to study distribution, habitat use and conservation status of the herpetofauna of the comoro islands. | we studied the non-marine reptile and amphibian species of the volcanic comoro archipelago in the western indian ocean, a poorly known island herpetofauna comprising numerous microendemic species of potentially high extinction risk and widespread, non-endemic and often invasive taxa. according to our data, the comoro islands are inhabited by two amphibian species and at least 28 species of reptiles although ongoing genetic studies and unconfirmed historical records suggest an even higher species ... | 2011 | 22207785 |
| feeding kinematics of phelsuma madagascariensis (reptilia: gekkonidae): testing differences between iguania and scleroglossa | the kinematics of feeding in the gekkotan lizard phelsuma madagascariensis (scleroglossa) was investigated using high-speed cinematography (200-300 frames s(-)(1)) and x-ray films (64 frames s(-)(1)). qualitative kinematic analysis of the head and jaw displacement of the prey to (capture) and within (reduction, transport, swallowing, licking) the buccal cavity are compared for two types of prey (crickets and mealworms) in 30 feeding sequences from four individuals. maximal displacement of struct ... | 1999 | 10574748 |
| molecular homology assessment and phylogeny in the lizard family opluridae (squamata: iguania). | the effect of utilizing secondary structure on multiple alignment and phylogeny reconstruction was examined for the mitochondrial 12s ribosomal rna and valine transfer rna genes in the lizard family opluridae. computer-generated multiple alignments were performed under parsimony using gap costs of 1-10 both with and without reference to secondary structure. alignments performed without secondary structure resulted in disruption of positional homology in some stems at all gap costs. number of mis ... | 1996 | 8812305 |
| tongue structure and function in oplurus cuvieri (reptilia: iguanidae). | the anatomy of the hyo-lingual apparatus in the iguanid lizard oplurus cuvieri has been studied by light microscopy and scanning electron microscopy. four areas were observed on the dorsal lingual epithelium of the lizard. tongue tips are covered with a smooth epithelium. closely packed flattened and cylindriform papillae cover the foretongue. the surface of the midtongue bears an unpapillose epithelium. short conical papillae are arranged on the two lateral posterior bundles of the tongue. at h ... | 1994 | 8154611 |
