Research Profile

Victoria Goodall’s research has mainly focused on the emerging field of statistical ecology – the application of various statistical methods to ecological data. Her Masters thesis entitled “Statistical Analyses of Artificial Waterpoints: their effect on the herbaceous and woody structure composition within the Kruger National Park” utilised three different datasets from the Kruger Park and applied various analyses to answer specific research questions. Her PhD thesis is entitled “Statistical Approaches towards Analysing Ungulate Movement Patterns in the Kruger National Park”. She fitted Independent Mixture, Hidden Markov and Bayesian State-space models to GPS location data obtained from sable antelope (Hippotragus niger), buffalo (Syncerus caffer) and zebra (Equus quagga) in the Kruger National Park. She has also been involved in a variety of research projects including a climate analysis of long-term weather records from South Africa’s National Parks; distribution of tree sizes in the Venetia-Limpopo Nature Reserve; assessment and management of the invasive shrub in South Africa, remote sensing and others.
 
She has been a referee of articles for the following peer-reviewed journals: International Journal of Climatology (2016), Journal of Applied Statistics (2015), South African Statistical Journal (2015), South African Statistical Association Conference Proceedings (2014 and 2017). She has been an external examiner of a Masters thesis for the University of Cape Town (2016).
