Seven out of the twenty-two yearlings, which were released in April/May 2011, were detected by the listening stations (hydro-phones) in the river 7 months after they were released.
University of Qld researchers and Tiaro Landcare volunteers spent 3 days downloading data from hydrophones and actively tracking tagged juvenile turtles. One juvenile was located which hadn’t been ‘heard’ of since July!! Must have been hiding. Thanks to support from Yamaha which ‘speeded up’ locating the turtles.
There was much cheering from the ‘Australian/Brazilian’ contingent when PhD candidate, Mariana Micheli-Campbell was announced the winner of the Best Student Presentation Award at the 9th Annual Symposium on Conservation & Biology of Tortoises & Freshwater Turtles in Orlando, Florida. It is a credit to the quality of her research and the support from her supervisors at the University of Qld, Eco-lab & Tiaro Landcare Group. Anders Rhodin, Chair of the IUCN Turtle & Tortoise Specialist Group spoke highly of her research into the impacts of incubation temperatures on the behaviour of hatchlings.
Researchers from the University of Queensland are conducting a tracking program of Mary River turtles. An adult female has been recorded at 7.4m ..this means she is hanging around on the bed of the river …..no wonder they are hard to find in the river..How long will she stay there? What food is there? Many questions to answer.

As part of University of Qld Honors students (Zac) research, very light transmitters were attached to 12 x one year old Mary River turtles and released into the river on 12th March. Great news that 7 of them were found one week later. Hopefully this is just the beginning of increasing our understanding of the behavioural aspects of young Mary River turtles.
A very relaxing and informative evening was spent on Monday evening with Professor Craig Franklin, PhD candidate Mariana A. de M. Campbell and Dr Hamish Campbell from the University of Qld. We greatly appreciated the effort Craig made to travel to Tiaro & fit us into his hectic schedule. It is a great partnership with benefits to both organisations, but most of all, we are learning more about the physiology and habitat requirements for this endangered turtle. An interesting discovery has been the huge temperature range of wild nests. Temperatures this season were recorded between 42deg C max and 17deg C min.
