We are seeking applicants for a PhD Scholarship at the University of Tasmania (Hobart, Tasmania, Australia). The project revolves around replicated field experiments across a range of agricultural catchments in northern Tasmania and south-west Western Australia, and we already have a companion PhD candidate at Murdoch University (Perth, Western Australia) to undertake the WA portion of this research.
The research seeks to test the common assumption that high biodiversity makes ecosystems resilient to disturbances. Observational studies documenting change after disturbance cannot identify ecological processes connecting diversity and ecosystem function, making field experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. Freshwater streams are excellent model systems to test these ideas. This project will use field experiments that manipulate flow disturbances in streams replicated in low (south-west WA) and high biodiversity (Tasmania) regions and across gradients of chronic background stress imposed by agriculture to investigate how biodiversity sustains functional ecosystems, and how much diversity can be lost before the resilience of a stream is irrevocably compromised. Both benthic biodiversity
and ecosystem processes will be measured.
There will be laboratory and smaller-scale field investigations to further unravel the underlying mechanisms, and the results will support food-web and community assembly modelling as the initial step to providing a synthetic platform to make predictions and test further hypotheses. The project is a collaboration between the University of Tasmania (hosting the Tasmanian PhD student), Murdoch University (hosting the WA PhD student) and Massey University (New Zealand), and is funded by the Australian Research Council Discovery Program.
Applicants for this scholarship should be able to address the following selection criteria:
Applicants interested in this project should contact Associate Professor Leon A. Barmuta (Leon.Barmuta@utas.edu.au , phone +61 (0)3 6226 2785) as soon as possible.
After initial discussions, prospective candidates may be required to prepare the following documents:
Due date for these documents will likely be 14th February 2020.
Once we have these documents, we will contact eligible candidates to progress to the University’s formal Scholarship application procedure.

Two post-doctoral positions are available at the University of Canberra in the newly established Centre for Applied Water Science, to work in partnership with CSIRO, a range of university, agency and Commonwealth government partners to carry out research on the critical issue of environmental water management in the Murray Darling Basin.
The positions are funded through the Commonwealth Environmental Water Office Basin-wide FLOW-Monitoring, Evaluation and Research (FLOW-MER) program. More information can be found here.

Lakes are one of the largest aquatic source of greenhouse gases (GHG) such as methane. Recent studies have highlighted the important role of small lake/ponds as a source of GHG. Australia is a dry continent and has a large number of small farm dams (ponds), but little is known about their contribution of GHGs. This fully funded project will study a number of dams from tropical to temperate regions along the east coast of Australia to determine how much GHG they emit, and the factors controlling these emissions. This project will use a combination of different techniques such as stable isotopes, cavity ring down spectroscopy, floating chambers, bubble traps and benthic process measurements.
Applicants will need to have an Honours or Master degree, undertaken in English, in a related field such as biogeochemistry, environmental chemistry, or closely related. The project will involve extended periods in the field, including in boats, sometimes in remote areas. The PhD scholarship will provide a tax-free stipend of $27,400 and tuition fees will be exempt. Interested applicants should send their CV highlighting their research background and interests in this area to Prof. Bradley Eyre – (firstname.lastname@example.org). Only short-listed applicants will be notified. Closing date November 8, 2019 although it may be extended longer if position is not filled. Starting date is flexible, but preferably early 2020.
The project will be undertaken in the Centre for Coastal Biogeochemistry (www.scu.edu.au/coastal-biogeochemistry) at Southern Cross University which received the highest rank of 5.0, well above world average, in geochemistry in the most recent assessment of research excellence by the Australian government.
