Golden Anniversary of the Australian Society of Herpetologists

Graphical Abstract Image

Herpetology (the study of frogs and reptiles) is a rapidly growing area of research which has had a long history within Australia. This special issue of the Journal commemorates the 50th anniversary of the Australian Society of Herpetologists, and contains a selection of papers on diverse herpetological projects.

Graphical Abstract Image

The ongoing accumulation of genetically divergent lineages that remain of uncertain taxonomic status and evolutionary significance is a major issue in evolutionary biology and conservation. Improved frameworks to systematically capture taxonomically unrecognised lineage diversity, increasing dissemination of biodiversity metadata, and emerging genomic technologies provide new opportunities to address this issue.

ZO14065A thermal profile of metabolic performance in the rare Australian chelid, Pseudemydura umbrina

Sophie G. Arnall, Gerald Kuchling and Nicola J. Mitchell
pp. 448-453
Graphical Abstract Image

To help understand how future climates might impact the critically endangered western swamp turtle (Pseudemydura umbrina), we produced a thermal response curve for the species by measuring standard metabolic rates. Our curve predicts a decline in performance beyond approximately 30°C, which is consistent with observations in the field and laboratory.

Graphical Abstract Image

We investigated levels of multiple paternity in loggerhead sea turtles (Caretta caretta) from three rookeries in Western Australia. We found highly variable rates unrelated to female population size (25% at Bungelup Beach, 86% at Gnaraloo Bay and 36% at Dirk Hartog Island).

Graphical Abstract Image

The biology and life-history traits of the vulnerable western sawshelled turtle, Myuchelys bellii, are presented for the first time. The long-term study (2002–2010) revealed delayed age at first breeding (males: 10 years, females: 20 years), low reproductive effort (14.3 eggs per female) and high survivorship (lifespan of over 40 years). Current threats and management actions are discussed.

ZO14071Foraging behaviour of the endangered Australian skink (Liopholis slateri)

Megan A. McKinney, Christine A. Schlesinger and Chris R. Pavey
pp. 477-482
Graphical Abstract Image

Slater’s skinks (Liopholis slateri), observed over a 7-month period, exhibited predominantly ambush predation. Juveniles foraged more frequently and further from burrows than adults. Ants were the most common prey item and juveniles targeted small ants more often than adults, moving further to capture these prey.

Graphical Abstract Image

Invertebrates can be important predators of amphibian eggs and tadpoles, but have been less well-studied than vertebrate predators. To determine the rate of consumption, common invertebrate predators (identified through field site surveys) were offered frog eggs and tadpoles in feeding trials. Freshwater crayfish and notonectids were identified as significant predators.

ZO14055Mating behaviour in pygmy bluetongue lizards: do females ‘attract' male lizards?

Mehregan Ebrahimi, Stephanie S. Godfrey, Aaron L. Fenner and C. Michael Bull
pp. 491-497
Graphical Abstract Image

Male lizards usually play an important role in mating behaviour. We discovered that female Australian pygmy bluetongue lizards (Tiliqua adelaidensis) moved around burrows when fewer male lizards visited them during the breeding season. We confirm that there are two mating strategies – selective and opportunistic – for this species as previously reported.

ZO14098Biology of the invasive delicate skink (Lampropholis delicata) on Lord Howe Island

David G. Chapple, Kimberly A. Miller, Kirilee Chaplin, Louise Barnett, Michael B. Thompson and Rebecca D. Bray
pp. 498-506
Graphical Abstract Image

We conducted the first detailed investigation of the invasive delicate skink (Lampropholis delicata) on Lord Howe Island (LHI), and examined its potential impact on the native biota. We conclude that, based on its distribution and abundance, the delicate skink has the potential to impact the diverse endemic invertebrate fauna on LHI.

ZO14059Piles of scats for piles of DNA: deriving DNA of lizards from their faeces

S. K. Pearson, S. S. Tobe, D. A. Fusco, C. M. Bull and M. G. Gardner
pp. 507-514
Graphical Abstract Image

Non-invasive genetic sampling using scats has a well established role in conservation biology, but has rarely been applied to reptiles. We evaluated various storage and DNA-extraction methods and identified a reliable method of deriving genotypes and sequences from gidgee skink, Egernia stokesii, scats. Results highlight the opportunity for using scat-derived DNA in lizard studies, particularly for species that deposit scats in piles.

ZO14085Random non-coding fragments of lizard DNA: anonymous nuclear loci for the Australian skink, Tiliqua rugosa, and their utility in other Egernia-group species

Talat Hojat Ansari, Terry Bertozzi, Jessica Hacking, Steven J. B. Cooper and Michael G. Gardner
pp. 515-518
Graphical Abstract Image

We developed 48 anonymous nuclear loci from the Australian skink, Tiliqua rugosa. These loci amplified across three lineages of T. rugosa (47 loci), in T. adelaidensis (37 loci) and in Egernia stokesii (34 loci). The loci showed variability within T. rugosa (22 loci) and among the three species (27 loci).
