Key piece discovered in the jigsaw puzzle that is reptilian sex determination
Posted in Pogona Research on Jun 28, 2017
The mechanism by which temperature exerts its influence on offpring sex has baffled scientists for over 50 years, since the phenomenon was first discovered. In a paper recently published in Science Advances (June 14, 2017), we believe we have discovered an important piece of the puzzle, a temperature sensitive transcripional modification to an influential chromatin modifying gene, Jumonji.
Tropical Turtle Diets
Posted in Turtle Research on May 31, 2017
Congratulations to Mick Welsh on publishing his honours work. There have been few community studies of Australian freshwater turtles. The present study examined the diet and microhabitat use of 5 species of freshwater turtles from the Daly River, Northern Territory. Dietary shift with age was observed for most turtle species, and between species there was differentiation of diet and microhabitat use. The study also showed that in the dry-season, freshwater turtles in a perennial tropical river like the Daly River rely on aquatic vegetation and molluscs.

Sex in Dragons -- Ecological drivers of transitions between GSD and TSD
Posted in Pogona Research on May 09, 2017
The Institute for Applied Ecology is seeking two PhD students with interests in population genetics and reptile ecology/physiology to investigate the field-based mechanisms of sex reversal in the dragon lizard, Pogona vitticeps.Expressions of interest before June 10.
Sex in Dragons -- Modelling evolutionary transitions
Posted in Pogona Research on May 08, 2017
Sex in Dragons – Modelling evolutionary transitions in sex determination. We are currently seeking a PhD student with interests in biological responses to climate change, evolution and theoretical biology to investigate the evolutionary and ecological dynamics of sex determination in the dragon lizard, Pogona vitticeps. Expressions of interest before June 10.
PhD Project Scholarship: Sex in Dragons
Posted in Pogona Research on May 05, 2017
Sex in Dragons – Pinning down the mechanisms of sex determination in a reptile. We are currently seeking at least one, but potentially several, PhD students with interests in genetics, evolution and developmental genomics to investigate the molecular mechanisms through which sex is determined in the Australian central bearded dragon lizard, *Pogona vitticeps*. Expressions of interest before June 10.
NCBI Pogona annotation complete
Posted in Pogona Research on Apr 24, 2017
NCBI has completed the annotation of the Pogona genome generated by the genetics and genomics team of the IAE, and made it widely available to the global research community. From the NCBI site, you can download the genome, view details of the annotation, blast any sequence against the genome, see the genes in "Gene", and in a few weeks, browse the genome using the NCBI Browser.
Workshop: Museum genomics in practice

Saving Piku -- PNG's iconic pig-nosed turtle
Posted in Turtle Research on Mar 30, 2017
Seven tribes, seven languages, seven cultures. The fate of the Pig-Nosed Turtle (Carettochelys insculpta) living in the Kikori River lies in the hands of all the local people who own its habitat in southern Papua New Guinea. Masters student Yolarnie Amepou gives her account of the Piku Project, operating out of Kikori in the PNG lowlands.
Risk-based ecohydrological assessement of flow regimes -- Qld DNRM
Posted in Turtle Research on Mar 29, 2017
Determining strategies to protect or restore flow regimes to achieve ecological outcomes is a focus of water policy and legislation in many parts of the world. A team from Queensland DNRM has developed a risk-based ecohydrological approach that links ecosystem values to desired ecological outcomes. This allows the relative risk from different flow management scenarios to be evaluated at relevant spatial-scales and a robust and useful foundation upon which to build the information needed to support water planning decisions. A case study using the eastern long-necked turtle is presented, with input from IAE staff and former students.
NCBI adopts Pogona
Posted in Pogona Research on Mar 20, 2017
The US National Center for Biotechnology Information (NCBI) has made the annotated genome sequence of Fabian, the ZZ dragon lizard, available to the international research community. The IAE made the genome available in 2013 through its local server, but we expect uptake to accellerate now that it is available through NCBI. Through the NCBI servier it is possible to BLAST sequence against the Pogona genome, pull down the sequences and annotation, and search for specific genes and regions. Well done to Denis O'Meally for making this all happen.
