Career Summary

Biography

Anita is a Lecturer in the School of Environmental and Life Sciences. She has been teaching in the discipline of Sustainable Resource Management at the Ourimbah Campus since 1999. She has taught a wide range of courses encompassing the sustainable management of land, water and vegetation, monitoring and assessment of vegetation, as well as community attitudes and values towards the environment. Her research interests focus on the disturbance ecology of plants and aims to improve the management of vegetation by understanding its response to natural and human disturbances. Research conducted by Anita and her students include the effects of soil disturbance and nutrients on grasslands, the effects of fire regimes on plant diversity, hanging swamps, tree hollows, dieback in woody wetlands within urbanising catchments and the population dynamics of threatened species. She has experience in rainforest, grassland, riparian/floodplain and wetland ecosystems. In collaboration with University of Newcastle geomorphologist, Professor Wayne Erskine, and researchers at Southern Cross University she has recently completed research on the vegetation at Widden Brook in the Hunter Valley of NSW. This research showed the important role that Casuarina cunninghamiana (River Oak) plays in river restoration (by enhancing the formation of in-channel benches) and that grazing by livestock reduces the recruitment of River Oaks. She also established the flow regimes typically experienced by River Oaks at Widden Brook. Anita is currently working on the riparian vegetation of Wollombi Brook, and its tributaries, with Professor Erskine. More research on the the links between vegetation, fluvial processes and sediment dynamics is needed if we are to effectively manage and restore riverine vegetation. Understanding how riparian and floodplain plant species respond to wet and dry climatic periods will also help us predict the impacts of climate change and determine environmental flow requirements. Since 2005, Anita has collaborated with the Australian Plants Society (Central Coast Group) and Gosford City Council on a field experiment established in the edge of a rainforest at Katandra Reserve near Gosford. The experiment is testing how useful the long-stem planting technique (developed by Bill Hicks for riparian zones) is for rainforest restoration. This research is aimed at improving on-ground restoration outcomes.

Research Expertise
My research is aimed at improving the management and conservation of vegetation through understanding its response to natural and human disturbances. *Threatened wetland plant communties - we have investigated woody wetland plant communities (Swamp Sclerophyll Forest and Parrammatta Red Gum woodland) on the Central Coast that may be impacted by increasing urbanisation of the surrounding catchment. *Riparian trees - we have investigated the role of Casuarina cunninghamiana (River She-oak) in channel contraction on Widden Brook in the Upper Hunter Valley, it's mortality due to floods and whether it's tree rings can be used to confirm the age of fluvial landforms. *Rare species - we have conducted research on a number of threatened species over the years, including Prostanthera junonis, Darwinia glaucophylla and Grevillea shiressii. *Restoration techniques - in collaboration with Gosford City Council and the Australian Plants Society (Central Coast Group), we established a field experiment in the edge of a rainforest edge at Katandra Reserve near Gosford to test how useful the long-stem planting technique (developed by Bill Hicks for riparian zones) is for rainforest restoration. *Tree hollows - we investigated the abundance and size of tree hollows in five native woodland species common on the Central Coast of NSW and also whether fire regime affects the abundance of tree hollows. *Soil disturbance and nutrient enrichment - a field experiment was established on the Northern Tablelands of NSW to investigate the response of grassland species to mechanical soil disturbance and nutrient enrichment. *Plant traits - comparisons of the traits of native and exotic grassland species showed that weeds have traits that enable them to avoid summer moisture stress and the impacts of grazing. The root morphology of grassland species has been investigated in root tubes and inter-specific differences can be explained by life-cycle, and the ability to access fertiliser and subsoil moisture. *Fire disturbance - we have investigated the effects of fire regime on plant diversity in Wallum Heath (dominated by Banksia aemula), response of Flannel flower (Actinotis helianthi) to fire regime and soil type and the effect of fire regime on the floristic composition of Hanging Swamps on the Central Coast of NSW.

Teaching Expertise
*Plant ecology and population processes, predominant vegetation types of Australia vegetation, botanical and adaptive features of Australian flora and plant identification. *Current issues in land and vegetation degradation, including fragmentation, weed invasion, altered fire regimes, altered hydrology, salinity and threatened plant species. *Strategies to manage Australian flora and plant communities including legislation, weed control, management and restoration of remnant vegetation, timber production and fire in vegetation systems. *Vegetation assessment and monitoring including sampling methods, assessment techniques for different management objectives and different spatial scales, tree hollow assessment, rare plant monitoring, vegetation as faunal habitat. *Values and attitudes towards the environment including environmental ethics and philosophies, effect of culture, environmental values, attitudes and behaviour, landscape preference, environmental politics, ecological economics, valuation techniques and economic instruments for resource management. *Strategies to change peoples attitudes and behaviour towards the environment, the use of ecological instruments and valuation techniques to manage natural resources, designing and implementing community surveys. *Physical, chemical and biological processes in lakes and streams, the hydrological cycle and water balance, water quality and aquatic habitat, ecological impacts of water use and water pollution. *Strategies to manage freshwater systems including wastewater and stormwater management, legislation, river restoration, water quality assessment and use of macro-invertebrates as indicators of river health.

Administrative Expertise
*Course co-ordination of four courses. *Honours Program Convenorr for the discipline of Applied Science from July 2006 - July 2010. *Timetable Co-ordinator for the School of Applied Science from 2000-2003. *Representative of the School of Applied Sciences (2003 - 2004) on the Faculty Student Recruitment Committee *Representative of the School of Environmental & Life Sciences (2009 - 2012) on the Faculty Community & Marketing Working Group

Collaborations
My primary research interest is in investigating the links between vegetation and river processes. This includes the role of vegetation in enhancing sedimentation and preventing erosion along waterways. This research will lead to an understanding of how vegetation is involved in the formation of fluvial landforms such as benches and floodplains. As there are feedbacks between fluvial-sedimentation processes, the vegetation and the hydologic regime, my research looks at the flow requirements of riverine plant species and their dependency on groundwater. This involves research on the recruitment of riverine (i.e. riparian and floodplain) species and the maintenance of mature populations. Species we are currently working on include Casuarina cunninghamiana (River Oak), Tristaniopsis laurina (Water Gum) and a number of native grass species. Further, I am interested in the application of this research to river restoration projects. This research needs to investigate environmental flow requirements that facilitate habitat creation and plant recruitment, as well as the use of the long-stem planting technique to obtain better on-ground outcomes for restoration projects. I have a secondary interest in the relationship between endangered woody wetland communities and their hydrologic regimes (i.e. flooding and groundwater requirements).

Lilly pilly (LP) fruit (Syzygium paniculatum Gaertn.) is widely grown in eastern Australia and has been used as food by indigenous Australians. However, there is limited information on its bioactivity. This study investigated the physicochemical and antioxidant properties of the crude fruit extract, identified its bioactive compounds and also assessed its potential anti-proliferative effect on pancreatic cancer cells. Our data showed that the LP extract was water-soluble and possessed a total phenolic content of 96 mg of gallic acid equivalents (GAE)/g, flavonoid levels of 52 mg catechin equivalents (CAE)/g, proanthocyanidin levels of 29 mg CAE/g. Several phenolic compounds such as gallic acid, chlorogenic acid, catechin and epicatechin were identified in the LP extract with levels of 0.39, 2.35, 0.47 and 2.9 mg/g, respectively. Results from six different antioxidant assays revealed that the LP extract pocessed potent antioxidant and free radical scavenging capacity. Although antioxidant capacity of the extract was lower than that of vitamin E, vitamin C and BHT, it could be significantly improved if the extract was to be further purified. We also showed that the LP extract (200 µg/mL) significantly reduced the viability of MiaPaCa-2 and ASPC-1 pancreatic cancer cells to levels comparable to that of the chemotherapeutic agent gemcitabine. For this reason lilly pilly should be further investigated for its health promoting and potential anti-cancer benefits, particularly for pancreatic cancer. © 2014 Elsevier GmbH.
