Rival recognition in the territorial tawny dragon (Ctenophorus decresii)
, 2005
"... Abstract The ability to discriminate between familiar and unfamiliar conspecifics is important in territorial animals as it allows animals to distinguish neighbours from nonneighbours. This prevents wasting time and energy in unnecessary aggressive interactions. I investigated the ability of adult ..."

males of a territorial lizard, the tawny dragon (Ctenophorus decresii), to distinguish familiar from unfamiliar rivals in a laboratory setting. Males significantly reduced their aggression levels in repeat interactions with familiar rivals and increased their aggression levels towards unfamiliar males
RESEARCH ARTICLE Testosterone-Induced Expression of Male Colour Morphs in Females of the Polymorphic Tawny Dragon Lizard, Ctenophorus decresii
"... Many colour polymorphisms are present only in one sex, usually males, but proximate mechanisms controlling the expression of sex-limited colour polymorphisms have received little attention. Here, we test the hypothesis that artificial elevation of testosterone in females of the colour polymorphic ta ..."

tawny dragon lizard, Ctenophorus decresii, can induce them to express the same colour morphs, in similar frequencies, to those found in males. Male C. decresii, express four discrete throat colour morphs (orange, yellow, grey and an orange central patch surrounded by yellow). We used silastic implants
The Effects of Residency and Body Size on Contest Initiation and Outcome in the Territorial Dragon,
, 2012
"... Empirical studies of the determinants of contests have been attempting to unravel the complexity of animal contest behaviour for decades. This complexity requires that experiments incorporate multiple determinants into studies to tease apart their relative effects. In this study we examined the comp ..."

the complex contest behaviour of the tawny dragon (Ctenophorus decresii), a territorial agamid lizard, with the specific aim of defining the factors that determine contest outcome. We manipulated the relative size and residency status of lizards in contests to weight their importance in determining contest
Band-e-Amir Lakes and Dragon Valley (Bamiyan): myths and seismicity in Afghanistan
"... Abstract: Located SW of the Hindu Kush range, the Band-e-Amir lakes and other continental bioherms around Bamiyan are famous for their ordering into terraces and their great variety of colours. Numerous legends, the earliest likely dating to the establishment of the Zoroastrian reli-gion, refer to t ..."

EDITORIALS Dragons ’Round the Fleece Again: STI571 Versus 1 Acid Glycoprotein
"... Ovid recounts the story of Jason and his Argonauts (1), who, after dealing with jealous harpies, wandering rocks, spectral armies, and fire-snorting bulls, approach the Golden Fleece only to find it guarded by a sleepless dragon who complicates the ease with which their prize might be grasped. In th ..."

Conspicuous males suffer higher predation risk: visual modelling and experimental evidence from lizards.
- Anim. Behav.
, 2003
"... Colour pattern variation is a striking and widespread phenomenon. Differential predation risk between individuals is often invoked to explain colour variation, but empirical support for this hypothesis is equivocal. We investigated differential conspicuousness and predation risk in two species of A ..."

of catastrophic failure in composite materials and in the Earth
, 2012
"... Abstract. Despite all attempts to isolate and predict extreme earth-quakes, these nearly always occur without obvious warning in real time: fully deterministic earthquake prediction is very much a ‘black swan’. On the other hand engineering-scale samples of rocks and other com-posite materials often ..."

Is body shape of varanid lizards linked with retreat choice?
"... Abstract. In our earlier analysis of Varanus body shape, size was a dominating factor with some qualitative phylogenetic patterns and grouping of species into ecological categories. With a phylogeny and an improved capacity to account for the effects of size, we have reanalysed our morphometric data ..."

After accounting for body size in the current analysis, four
The Archean deep-marine environment: turbidite architecture of the Burwash Formation, Slave Province, Northwest Territories. Canadian Journal of Earth Sciences
, 2004
"... Abstract: The Slave Province is an Archean craton that contains an unusually large proportion of preserved sedimentary rock, including thick turbidite successions. The Burwash Formation is exposed in the southern Slave Province between the Anton and Sleepy Dragon basement massifs. At the base of the ..."
