| a new velvet gecko (oedura: diplodactylidae) from groote eylandt, northern territory. | over the last decade, the combination of biological surveys, genetic diversity assessments and systematic research has revealed a growing number of previously unrecognised vertebrate species endemic to the australian monsoonal tropics. here we describe a new species of saxicoline velvet gecko in the oedura marmorata complex from groote eylandt, a large island off the eastern edge of the top end region of the northern territory. oedura nesos sp. nov. differs from all congeners in combination of m ... | 2020 | 33055784 |
| systematic revision of the marbled velvet geckos (oedura marmorata species complex, diplodactylidae) from the australian arid and semi-arid zones. | lizards restricted to rocky habitats often comprise numerous deeply divergent lineages, reflecting the disjunct nature of their preferred habitat and the capacity of rocky habitats to function as evolutionary refugia. here we review the systematics and diversity of the predominantly saxicoline australian marbled velvet geckos (genus oedura) in the australian arid and semi-arid zones using newly-gathered morphological data and previously published genetic data. earlier work showed that four large ... | 2016 | 27394333 |
| how body size affects middle-ear structure and function and auditory sensitivity in gekkonoid lizards. | gekkonoid lizards increase in body size throughout life, and the present study investigates whether changes in auditory function accompany these increases. middle-ear structures in four groups of animals, adults and juveniles of two gekkonoid species (eublepharis macularius and oedura marmorata), were examined. tympanic membrane velocity and phase were also measured in all four groups. an indication of peripheral auditory function was obtained for each group by measuring compound action potentia ... | 1998 | 9438825 |
| effects of age and size in the ears of gekkotan lizards: auditory sensitivity, its determinants, and new insights into tetrapod middle-ear function. | do related, differently sized species differ in size-related structural or functional traits merely because they mature at different points of a uniform allometric ontogenetic growth curve, or do they evolutionarily diverge? we tested ears of gekkotan lizards through experiments distinguishing the two. auditory sensitivity was assessed by compound action potential (cap) thresholds in eight species. the best thresholds characterizing species ranged 22-72 db sound pressure level at 0.5-1.0 khz. di ... | 2008 | 18239935 |
| proliferative thyroid lesions in three diplodactylid geckos: nephrurus amyae, nephrurus levis, and oedura marmorata. | over a 5-mo period, three diplodactylid geckos housed at the national aquarium were diagnosed with proliferative thyroid lesions: a rough knob-tail gecko (nephrurus amyae), a smooth knob-tail gecko (nephrurus levis), and a marbled velvet gecko (oedura marmorata). clinical signs included an intraoral mass or ventral throat swelling (or both), oral bleeding, and weight loss. both of the knob-tail geckos died. the histologic diagnosis for the rough knob-tail gecko was thyroid carcinoma with metasta ... | 2012 | 22448520 |
| energetics and water flux of the marbled velvet gecko (oedura marmorata) in tropical and temperate habitats. | the gecko oedura marmorata was studied in two different climatic zones: the arid zone of central australia and in the wet-dry tropics of northern australia. doubly labelled water was used to measure field metabolic rate (fmr) and water flux rates of animals in the field during the temperate seasons of spring, summer and winter, and during the tropical wet and dry seasons. fmrs were highest in the tropical wet season and lowest in the temperate winter. the geckos in central australia expended les ... | 1998 | 28308064 |
| karyotypic variation in the australian gekko phyllodactylus marmoratus (gray) (gekkonidae: reptilia) | the gekko phyllodactylus marmoratus has at least three distinct chromosome races; 2n=39, 2n=26 zz/zw and 2n=34. specimens from these races are morphologically distinguishable, have a degree of habitat specialization and occur in a defined distribution. the 2n=36 race found in eastern australia is the presumed primordial type. the 2n=34 race occurs in western australia and is regarded as a fusion derivative. the 2n=36 zz/zw race, which is only found on the murray river system in eastern australia ... | 1976 | 1248335 |
