Phylogenetic relationships among hylid frogs of the Australian region were studied by micro-complement fixation comparisons of serum albumin. Although our data support current species-group arrangements, we do not find good agreement between our phylogenetic hypotheses and those derived from morphological and karyological studies. Immunological analyses provide data which allow the construction of a phylogeny for the Australian radiation of the speciose genus Litoria, and suggest dividing the species of Litoria examined into five major species-assemblages, each of which is probably monophyletic. The sister- group relationship between the Litoria aurea group and Cyclorana is confirmed, and the diphyletic origin of the terrestrial hylids is supported. The radiation of Australian hylids is monophyletic with respect to the outgroup taxon (Hyla) used in this study, and the origin of diversification within the genus correlates well with estimates of the final separation of Australia from Antarctica-South America. Preliminary data suggest that the endemic New Guinean taxa (Nyctimystes and the montane Litoria) are closely related to the Australian 'freycineti' assemblage within Litoria. Albumin from Litoria infrafrenata cross-reacted poorly with all available Australian antisera, suggesting that this species may have originated independently of the rest of the Australian hylids. Our data support the classification of Australian tree frogs as hylids, rather than as leptodactyloid offshoots.

For many taxa, new records of non-native introductions globally occur at a near exponential rate. We undertook a systematic review of peer-reviewed publications on non-native herpetofauna, to assess the information base available for assessing risks of future invasions, resulting in 836 relevant papers. The taxonomic and geographic scope of the literature was also compared to a published database of all known invasions globally. We found 1,116 species of herpetofauna, 95% of which were present in fewer than 12 studies. Nearly all literature on the invasion ecology of herpetofauna has appeared since 2000, with a strong focus on frogs (58%), particularly cane toads (Rhinella marina) and their impacts in Australia. While fewer papers have been published on turtles and snakes, proportionately more species from both these groups have been studied than for frogs. Within each herpetofaunal group, there are a handful of well-studied species:R. marina,Lithobates catesbeianus, Xenopus laevis,Trachemys scripta,Boiga irregularisandAnolis sagrei. Most research (416 papers; 50%) has addressed impacts, with far fewer studies on aspects like trade (2%). Besides Australia (213 studies), most countries have little location-specific peer-reviewed literature on non-native herpetofauna (on average 1.1 papers per established species). Other exceptions were Guam, the UK, China, California and France, but even their publication coverage across established species was not even. New methods for assessing and prioritizing invasive species such as the Environmental Impact Classification for Alien Taxa provide useful frameworks for risk assessment, but require robust species-level studies. Global initiatives, similar to the Global Amphibian Assessment, using the species and taxonomic groups identified here, are needed to derive the level of information across broad geographic ranges required to apply these frameworks. Expansive studies on model species can be used to indicate productive research foci for understudied taxa.

Vegetation dominated by lancewood (Acacia shirleyi) occurs extensively across the Northern Territory and Queensland. The vertebrate species (birds, mammals, reptiles and frogs) composition was sampled at 61 patches of lancewood in the Northern Territory (including 22 patches where quadrats were intensively sampled), and the distribution of species was related to a wide range of environmental characteristics, spatial variables, disturbance and season. Of 165 species recorded from lancewood patches, eight species were recorded from more than half of the sampled patches: Pachycephala rufiventris, Pomatostomus temporalis, Rhipidura leucophrys, Cracticus nigrogularis, Melanodryas cucullata, Geopelia cuneata, G. placida and Macropus robustus. Environmental variation within sampled lancewood sites was described by classification of 51 quadrats into 7 classes, and the 61 patches into 5 classes. Vertebrate species showed limited association with this classification, with a few species associated with the occasional co-dominant tall shrub Macropteranthes kekwickii, other species associated with variation in rockiness or soil texture, and other species associated with variation in the occurrence of Eucalyptus species within lancewood vegetation. An ordination of all quadrats by their vertebrate species composition suggested a loose patterning associated mainly with latitude and, less strongly, soil texture and co-occurring tree/shrub species (notably Eucalyptus and Macropteranthes). Suggesting a depauperate and poorly defined vertebrate community in lancewood, quadrats in small isolated lancewood patches had more species than those in large patches, and this pattern was shown for many individual species. Lancewood patches showed some impact of grazing and logging, but this was generally minor and could not be demonstrated to have any consistent relationship with the abundance of individual species. In contrast, effects of fire were generally more severe, and were negatively associated with the abundance of relatively many species. Lancewood vegetation is not represented in any conservation reserve in the Northern Territory.

Animal species identification based on their sound has received attentions from researchers. This is to establish fast and efficient identification method. Identification of frogs have been one of the examples where research activities have shown some progress. Mel Frequency Cepstrum Coefficient (MFCC) and Linear Predictive Coding (LPC), coupled with k-th Nearest Neighbor (k-NN) or Support Vector Machines (SVM) have been the favorate approachs used by researchers. Quite recently, a new classification and identification method of sound using entropy-based approach for species identification of Australian frogs was proposed. Shannon, Rènyi and Tsallis entropy were used as features of extraction for the purpose of pattern recognition. Result shows that the full entropy-based animal sound identification system has successfully identified most of the frog species used in this study. The overall classification accuracy is as high as 91% with two failures from nine samples at 70% and 40%, respectively. A comparative analysis highlights the advantages of full entropy approach over conventional frequency spectral and hybrid methods. This is shown especially in the running time of a computer that required to complete the species identifications process. The result presented in this paper indicates that full entropy-based method can be used for faster frog species identification.
