Abstract:
Abstract New Guinea has been considered both as a refuge for mesic rainforest-associated lineages that contracted in response to the late Cenozoic aridification of Australia and as a centre of biotic diversification and radiation since the mid-Miocene or earlier. Here, we estimate the diversity and a phylogeny for the Australo-Papuan forest dragons (Sauria: Agamidae; ~20 species) in order to examine the following: (1) whether New Guinea and/or proto-Papuan Islands may have been a biogeographical refuge or a source for diversity in Australia; (2) whether mesic rainforest environments are ancestral to the entire radiation, as may be predicted by the New Guinea refuge hypothesis; and (3) more broadly, how agamid ecological diversity varies across the contrasting environments of Australia and New Guinea. Patterns of lineage distribution and diversity suggest that extinction in Australia, and colonization and radiation on proto-Papuan islands, have both shaped the extant diversity and distribution of forest dragons since the mid-Miocene. The ancestral biome for all Australo-Papuan agamids is ambiguous. Both rainforest and arid-adapted radiations probably started in the early Miocene. However, despite deep-lineage diversity in New Guinea rainforest habitats, overall species and ecological diversity is low when compared with more arid areas, with terrestrial taxa being strikingly absent.

Abstract:
Ludwig Glauert (1952, p. 168) established the name Amphibolurus barbatus microlepidotus (= Pogona microlepidota) for a new agamid species (family Agamidae) from the type locality of “Drysdale River Mission, North Kimberley”, Western Australia and listed two specimens of the Western Australian Museum (WAM) collected by “Rev. Father [Raymundus] Salinas” in July 1922 as “types”. The two registrations forming the type series presented by Glauert were WAM R591 and WAM R592, which in accordance with Article 72.1.1. of the International Code for Zoological Nomenclature (the Code; International Commission on Zoological Nomenclature 1999) are considered syntypes. The two registrations presented by Glauert in the original publication (WAM R591–592) are in error, both registrations are associated with specimens of other species not matching the description or collection data presented by Glauert in the original description of A. b. microlepidotus. The specimen associated with WAM R591 is a Pseudonaja affinis Günther, 1872 (Serpentes: Elapidae), collected by M. Sweeting from the suburb of Leederville in Perth, Western Australia and WAM R592 a specimen of Neelaps calonotus (Duméril, Bibron, & Duméril, 1854) (Serpentes: Elapidae) collected by C. Thomas from the Perth suburb of West Guildford (now Bassendean), Western Australia (Fig. 1). The P. affinis specimen (WAM R591) is purportedly a whole specimen stored in a 75% ethanol solution; however, extensive searches failed to locate the specimen in the WAM collection and it is presumed lost or disposed of. In the early half of the 20th century, large and easily identifiable specimens were sometimes disposed following identification, registration and collection of morphological data due to their preservation and storage difficulty (see Smith 1981). The N. calonotus specimen (WAM R592) is now an alizarin-stained body in a glycol solution with skin stored separately in 75% ethanol (Fig. 1). The erroneous registration numbers provided by Glauert technically placed the name A. b. microlepidotus into synonymy with either N. calonotus or P. affinis depending on lectotype selection.

Abstract:
Radiotelemetric monitoring of 18 free-ranging frillneck lizards in Kakadu National Park, combined with dissection of museum specimens, provided extensive data on the natural history and general ecology of this large and spectacular lizard. Activity patterns and reproductive cycles are highly seasonal, with lizards inactive during the drier (and cooler) months of the year. Frillnecks are primarily arboreal and are relatively unselective with regard to the species of tree used except that one common species, Eucalyptus confertyora, is avoided. Telemetered lizards usually clung to branches high in the canopy. During the mating season (November-December), males had larger activity ranges than did females (means of 2.5 vs 0.7 ha) and made longer daily movements (means of 69 vs 23 m). Frillneck lizards bask briefly in the morning, but body temperatures follow ambient temperatures for most of the day. Thermal heterogeneity in the lizards' habitat is low, so opportunities for behavioural regulation (especially reduction) of body temperature are limited. Body temperatures are highly correlated with air temperatures and are often close to 40�C. Female frillnecks are considerably smaller than males, and they produce 4-13 eggs during the wet season. Chlamydosaurus are apparently unique among reptiles in using bipedal locomotion during routine foraging. These lizards are 'sit and wait' predators, descending from arboreal vantage points to seize lepidopteran larvae or massed swarms of hymenopteran or isopteran alates. Many different types of insects are eaten, but vertebrate prey items are rarely taken.

Abstract:
Twelve species of nematode were recovered from the gastrointestinal tract of 115 lizards in the genus Pogona (Agamidae) in Western Australia. Seven species belonged to the Physalopteridae, and three new species are described: Abbreviata pilbarensis, sp. nov., occurs only in the Pilbara region and possesses relatively small dorsal and ventral pseudolabial teeth, inconstant and irregular small denticles on the medial pseudolabial surface, left spicule more than twice the length of the right, vulva with short wide posteriorly directed tubular extension, and thick-shelled eggs; Abbreviata anomala, sp. nov., occurs throughout the State, and possesses small pseudolabia, small dorsal and ventral pseudolabial teeth, an even row of 40-60 small denticles lining the medial pseudolabial surface, left spicule 3-4 times the length of the right, five pairs of pedunculate pericloacal papillae, and females with truncated rounded tail and vulva 3-5% of body length from anterior end; Kreisiella lesueurii, sp. nov., was identified from the south-west, and possesses a row of fine even denticles extending the width of the medial pseudolabial margin, no apical, dorsal or ventral pseudolabial teeth, a restricted area of tubercles on the male ventral tail surface, a short and thick right spicule, four pairs of pedunculate pericloacal papillae, caudal alae not meeting anteriorly and not extending to the tip of the tail, and females with truncated rounded tail and anteriorly placed vulva. The male of Maxvachonia brygooi is described: it possesses lateral alae and differs from M. chabaudi only in the larger size of the gubernaculum and spicules. Other species recorded were Strongyluris paronai, Physalopteroides filicauda, Skrjabinoptera goldmanae, Abbreviata antarctica, Pseudorictularia disparilis, one species of Oxyuroidea, and two species of Trichostrongyloidea. Concurrent infection with M. brygooi and S. goldmanae was positively correlated, and prevalence and intensity of both species increased with host size, in Pogona minor mitchelli. Prevalence and intensity of infection, and species diversity, were highest in the northern, subtropical parts of the State, and lowest in the drier central and southern inland. Cysts containing physalopteran larvae were present in the stomach wall of many hosts; prevalence and intensity of cysts was highest in the northern area.

Abstract:
The systematic status of the dragon lizards Tympanocryptis lineata pinguicolla and T. tetraporophora (Agamidae) was examined by allozyme electrophoresis and multivariate morphological techniques. Both taxa exhibited considerable genetic and morphological differentiation from each other and from most other members of the T. lineata species group examined. The recognition of T. tetraporophora at the specific level is confirmed and T. l. pinguicolla is raised to full specific status. The remaining subspecies of T. lineata are each genetically well differentiated from each other and may represent full species. Allozyme analysis of specimens from the T. cephalus/intima complex in eastern Australia was problematic because of small samples and heterogenous distributions of alleles, a more extensive sampling being required to resolve their status. A key is provided for identification of species of Tympanocryptis in south-eastern Australia.

Abstract:
Maxvachonia brygooi, Strongyluris; paronai, Physalopteroides filicaudo, Abbreviata anomala, A. confusa, Skrjabinoptera goldmanae and unidentified species of Oxyuroidea and Trichostrongyloidea were recovered from the gastrointestinal tract of the frillneck lizard, Chlamydosaurus kingii, from northern Australia. The nematode fauna is similar to that found in Pogona mitchelli (Agamidae). Skrj. goldmanae was the most abundant nematode; adults were attached to the stomach wall with their anterior ends buried within the submucosa. The hosts' histopathological responses consisted of collagen proliferation with macrophage infiltration, and evidence is presented that worms in the tissues die and are resorbed. Possible explanations for this mode of feeding and for the host reaction are discussed in terms of the annual activity cycle of the lizard host.

Abstract:
Communication signals underpin the social lives of animals, from species recognition to mate selection and territory defense. Animal signals are diverse in structure between and within species, with the diversity reflecting interacting factors of shared evolutionary history, constraints imposed on senders and receivers and the ecological context in which signalling takes place. The dragon lizards of Australia (family Agamidae) are known for their movement-based visual displays and are useful models for how ecology influences behaviour. However, we know little about the communication strategies of many species. Our aim here was to provide new knowledge on some of these species, focusing on the north-west of Western Australia. We filmed within-species pairwise interactions of Diporiphora superba, D. bennetti, D. sobria and Ctenophorus isolepis isolepis. We describe and quantify for the first time push-up displays by D. superba and C. isolepis isolepis and tail waving displays of D. bennetti. Only D. sobria did not generate movement-based visual signals. We have confirmed that more species engage in such behaviour than previously reported, but further work is required to document the full repertoire of these species. The implications of our work are discussed in the context of signal structure, function and environmental context.

Abstract:
The Jacky dragon (Amphibolurus muricatus), a semi-arboreal agamid lizard native to south{u00AD}eastern Australia, competes for territories using a rapid sequence of distinct body movements initiated by tail flicks and followed by foreleg waves, head bobs and push-ups. Detection of these signals is particularly challenging against a background of wind-blown plants, and it has been shown that lizards overcome 'motion noise' by adjusting the duration and intensity of the tail flick. Clearly signal efficacy is limited by detection problems, but the visual capabilities of the Jacky dragon, or other lizards for that matter, remain largely unknown. In order to better our understanding of the relationship between visual system design, ecology and phylogeny, and to identify how sensory capabilities relate to signal design, I examine the Eye of the dragon. Jacky dragons are small, fast-moving insectivorous predators which are typically found basking motionless on elevated perches. A broad visual field provides almost complete coverage of their surrounds irrespective of body posture or orientation of the head, and allows lizards to remain vigilant to predators, and to detect potential prey or conspecific intruders entering their territory. Using a custom-built light chamber I show that that they have a dynamic pupil which responds quickly to shifts in ambient light intensity, presumably allowing lizards to maintain high spatial and temporal resolution for accurate control of daily movements through their dynamic environment. I develop a schematic model of the Jacky dragon eye and map the topography of the retina, revealing a centrally located region of elevated photoreceptor and ganglion cell density and a deeply incised foveal specialization. Although the Jacky dragon retina comprises ganglion cell somata that are characteristically small in size, a subset of disproportionately large ganglion cells occupy the peripheral retina. If these giant ganglion cells share functional homologies with the giant ganglion cells reported among other animals, their high concentration in the retina's periphery would increase the likelihood of detecting salient visual motion in the peripheral field of vision, integral in the detection of prey and potential predators. I hypothesize that the introductory tail flick signal is designed to stimulate these giant ganglion cells, capturing the intended receiver's attention and orienting their gaze. This visual grasp reflex allows later signal components to be viewed though a centrally placed fovea, where high photoreceptor and ganglion cell densities provide superior visual acuity.
