The hypotheses that these body size shifts are due to strong selection imposed by the size of available prey items, rather than shared evolutionary history, are supported and are consistent with the notion that adaptive plasticity also has played an important role in body size changes.

A mitochondrial gene tree for representative species of all the genera in the subfamily Myobatrachinae, with special emphasis on Crinia and Geocrinia, concludes that the phylogenetic relationships among Crinia species are well resolved with strong support for a number of distinct monophyletic clades, but more data are required to resolve relationships among these major Crinia clades.
Molecular phylogeny of the Australian venomous snake genus Hoplocephalus (Serpentes, Elapidae) and conservation genetics of the threatened H. stephensii

On the basis of genetic distinctiveness, Hoplocephalus bitorquatus should receive high conservation priority; and managers should treat the Queensland and NSW populations of H. stephensi as separate conservation units.
Shifting sands and shifty lizards: molecular phylogeny and biogeography of African flat lizards (Platysaurus).
Isolation and characterization of novel microsatellite markers from the Australian tiger snakes (Elapidae: Notechis) and amplification in the closely related genus Hoplocephalus
Seven microsatellite loci (out of 20 primer pairs designed) that exhibited the cleanest and strongest banding patterns for the Eastern tiger snake Notechis scutatus are provided.
Molecular determination of paternity in a natural population of the multiply mating polygynous lizard Eulamprus heatwolei
Neither male home range ownership nor body size is significantly correlated with the number of paternities a male obtained, which suggests a polygynous mating system for this species.
Tuber transmission of ‘Candidatus Liberibacter solanacearum’ and its association with zebra chip on potato in New Zealand

Zebra chip, an emerging disease of potatoes, has recently been associated with ‘Candidatus Liberibacter solanacearum’ in New Zealand. The phloem-limited bacterium is known to be vectored by the…
Characterisation of New Zealand Fusarium populations using a polyphasic approach differentiates the F. avenaceum/F. acuminatum/F. tricinctum species complex in cereal and grassland systems.
Molecular phylogeny of viviparous Australian elapid snakes: affinities of Echiopsis atriceps (Storr, 1980) and Drysdalia coronata (Schlegel, 1837), with description of a new genus
These data strongly support a sister group relationship between ‘Echiopsis’ atriceps and the Australian broadheaded snakes of the genus Hoplocephalus with a bootstrap value of 99%.
Conservation genetics of the endangered grassland earless dragon Tympanocryptis pinguicolla (Reptilia: Agamidae) in Southeastern Australia
Compared to studies on other reptile groups in which the same fragment of DNA was used, the differences found between the ACT and Cooma populations are more in line with species-level differences thandifferences within a single species and suggests that these populations should be considered separate taxonomic units.
