Research Students

Until 2015, I had a fantastic job working as an ecology researcher at Charles Sturt University. I left that position in 2015 and now work as a science writer. This page lists all the wonderful PhD, Masters and Honours students I supervised during my time at CSU. This list is now historical and will no longer be updated. You can read about my recent work at my new web site.


Current PhD and Masters Students

Ian Cole

How can we restore diverse understoreys dominated by native grasses and wildflowers in degraded remnant woodlands? Ian Cole’s PhD focuses on this important conservation issue. In a large experiment in southern NSW, Ian is examining how disturbances such as crash grazing and burning, and changes to soil nutrient levels influence the establishment and growth of native grasses in degraded woodlands. Ian’s work supports a large project that is co-supervised by Dr Suzanne Prober (pictured) of CSIRO and I. This project is funded and supported by many organizations, including the NSW Environmental Trust, Murray CMA, DECCW NSW, the Future Farm Industries, CRC and Sugar Australia.

Erika Cross

Erika

Why do woodlands have such an open structure? Is it because disturbance prevent recruitment, keeping stands at lower densities than might otherwise occur? Or is it because big, old trees have wide root systems that prevent other trees from regenerating near them? Are woodlands kept open because of frequent disturbances or inadequate resources? Answers to these questions underpin many important issues about woodland stand structure, future stand dynamics, and stand management (such as thinning) in remnant and regenerating sites. Erika seeks answers to these questions by surveying leaf area index and using experimental transplants in regenerating woodlands and forests in central Victoria. Her results will improve our understanding of how woodlands change as they get older, and of the processes that influence tree spacings and site occupancy. I co-supervise Erika’s PhD project with Dr John Morgan. Email Erika: ecross@csu.edu.au

Karolina Petrovic

Mistletoes and possums have little in common in evolutionary terms, but possess similar functional roles in forests and woodlands – both ‘feed’ on dominant forest trees. But do they select similar or different trees? Do the defensive chemicals that trees produce to deter possums also deter mistletoes? Karolina is investigating these questions and many more in her project on mistletoes, possums and tree leaf chemistry. Karolina’s project is supervised by Associate Professor David Watson and I.

Mel Schroder

Alpine areas support many of Australia’s endemic ecosystems, which are highly vulnerable to climate change. Parts of the alps are also threatened by exotic weed invasion. The diversity of weed species in the alps has increased rapidly since the 1960’s. Developing strategies to work out which weeds pose the most serious threats to natural areas and which ecosystems are most vulnerable to invasion is a challenge. Mel is tackling this challenge by exploring the causes of weed invasion. Currently she is focusing on how soil nutrients vary across altitudinal gradients, and how plant traits associated with nutrient acquisition vary among weeds and native plants. High nutrient levels are known to promote exotic plant invasions in many ecosystems. Is this also true for the Australian alps? Mel is a part-time Masters research student, and works with the NSW National Parks and Wildlife Service. I am co-supervising Mel’s project with Dr Keith McDougall of NSW NPWS. Email Mel: Mel.Schroder@environment.nsw.gov.au

Lisa Smallbone

Which birds get the most benefit from regenerating native vegetation in agricultural areas? Lisa is working in the Rushworth region in central Victoria, where she is documenting how shrubs and trees are regenerating as agricultural areas change to hobby farms, and how bird communities change as regenerating vegetation gets older. I co-supervise Lisa’s PhD project with Drs Alison Matthews and John Morgan. Email Lisa: lsmallbone@csu.edu.au. See Lisa on ResearchGate and Google Scholar.

Joey Walters-Nevet

JoeyWe know a lot about how higher plants and animals change when we clear and plant native vegetation. But what happens to soil microbes? How well do microbes recover when native vegetation regenerates? In this fascinating project Joey aims to discover how soil microbes differ between remnant forests, cleared farmland and – most importantly – in regenerating forests and shrublands that have recovered after agriculture and livestock have been removed. Do remnant paddock trees provide refuges from which microbes can re-colonize regenerating areas? I co-supervise Joey’s PhD project with Assoc. Professor David Watson.
