New insights to reptile sex

Posted in Pogona Research on Jul 04, 2018

Male or female? In many reptiles sex determination is temperature-dependent. But how this works has been a mystery for 50 years... New insights have emerged from work by Chutian Ge and his collegues who show that ancient conserved epigentic machinary is involved in the thermosensitive regulation of key sex genes. Team Pogona was asked to provide a perspective on the new findings. We have received many enquiries since. In this post, we explain more fully what we believe is going on.

Writers' Retreat

Posted in Uncategorized on Jun 24, 2018

Science is not complete until the results are published. This week, a small group of scientists from the University of Canberra have gathered at Kioloa, on the coast of NSW, to mount a collective assault on writers' block, to put their heads down and write that paper. Some good science, some good fun, and some good outcomes.

dartR -- an R package for SNP data

Posted in Uncategorized on May 14, 2018

Our exciting new R package that appeared recently in Molecular Ecology Resources -- dartR for facilitating analysis of SNP data generated from reduced representation genome sequencing -- has had an upgrade. We are pleased to announce that version 1.0.5 has now been uploaded to CRAN, and has a number of new features -- population assignment, links to PAUP SVDQuartets analysis, improved fixed difference analysis and other new features.

National Geographic funds lizard sex

Posted in Pogona Research on Mar 15, 2018

Congratulations to IAE student, Duminda Dissanayake, on receiving a grant from the National Geographic to progress understanding of sex reversal by temperature in the three-lined skink and to advance broader implications of sex reversal more generally. Sex reversal in the XX/XY skink complements sex reversal in the ZZ/ZW dragon very nicely indeed.

Asian-New Guinea Turtle Makeover

Posted in Turtle Research on Mar 13, 2018

Conservationists, wildlife biologists and other experts converted on Singapore Zoo this week for intensive scrutiny of what is known of the freshwater turtles of Asia, New Guinea and environs. They paint a sober picture, with many species moving to vulnerable or from vulnerable to endangered, or from endangered to critically endangered.

Profiling a rapid extinction event

Posted in Turtle Research on Mar 13, 2018

The Bellinger River Turtle, Myuchelys georgesi, is in trouble. A virus recently decimated the population, virtually extirpating the adult population from its restricted native range. Effectively, only juveniles remain. In this article, which appeared today an Biological Conservation, we outline our views on the causes of the decline.

Turtles in Trouble

Posted in Turtle Research on Mar 03, 2018

There is no vertebrate group facing greater survival problems today than turtles. Turtles saw the great dinosaurs come and go and are now facing their own extinction crisis -- John Behler. Scientists have now revised their assessment of the 25 turtles most at risk of extinction, to increase the imperative for governments to take action. Two Australian freshwater turtles are on the list.

IAE students awarded CSIRO Scholarships

Posted in Pogona Research on Jan 24, 2018

Congratulations to Sarah Whiteley and Duminda Dissanayake on the receipt of CSIRO Scholarships in support of their PhD work. These scholarships carry both a top-up to living allowance and project funds. Both students are working within Team Pogona.

Mohamed bin Zayed Species Conservation Fund supports pig-nosed turtle conservation

Congratulations to Matt Young and Yolarnie Amepou on securing funding from the Mohamed bin Zayed Species Conservation Fund for their work in Papua New Guinea. The project is administered by the Institute for Applied Ecology at the University of Canberra in partnership with the Piku Biodiversity Network in PNG.

Masters in Automation of High-throughput Genotyping

Posted on Nov 29, 2017

Welcome to Julian Hausner who begins his Masters degree in the IAE working on automation of high-throughput genotyping. His is an applied Co-Op masters degree with industry partner Diversity Arrays Technology. Julian plans to bring his existing expertise in laboratory chemistry and chemical safety procedures and experience and knowledge of laboratory automation to bear on new applications for automation of the laboratory workflow for UC associate, Diversity Arrays Technology Pty Ltd.
