Research Background


My association with Professor Shine and his lab began way, way back in 1995 when I undertook an Honours degree in Science, majoring in reptile biology. My Honours project involved an investigation into the long-term effects of incubation temperatures on hatchling skinks (Bassiana duperreyi), from the Brindabella Ranges near Canberra. Since graduating with First Class Honours, I have been employed as one of Rick's full-time research assistants, where my duties are many and varied. My principle role is to assist Rick with his continued research on the incubation biology of Bassiana duperreyi. A typical season usually involves monitoring natural nest temperatures using miniature data loggers, collecting eggs from the field, and then incubating them in the laboratory at a variety of temperatures.


Once the hatchlings have emerged, we assess their morphology, and various other behavioural characteristics, in an effort to work out the ecological and evolutionary consequences of a female's choice of egg-laying site. All of the hatchlings are then released back into the field. And when I'm not looking after hundreds of wriggling lizards, I try to assist Rick's many students with their research projects, and keep the lab tidy!

I've been extremely fortunate during my time as a research assistant, having had the opportunity to accompany Rick to far flung places in search of reptiles. In 1998 I travelled to Manitoba to assist with research on the great gartersnake emergence and breeding frenzy that occurs during the short Canadian spring and summer. It was truly an adventure of a lifetime.


Then in July 2002 I spent a week in New Caledonia helping Rick with his research on the natural history and foraging tactics of the turtle headed seasnake (Emydocephalus annulatus). They are amazing and quite delightful creatures to work on.

My latest research adventure took me to Fogg Dam, near Humpty Doo in the Northern Territory, to assist Rick and his post-doc Greg Brown with a study on the foraging tactics of Macleay's water snake (Enhydris polylepis). Fogg Dam is an extraordinary and beautiful place. And the 5m saltie that took up residence in the Dam during the week certainly added a new dimension to my experience of reptile research!
