As an aspiring spatial and environmental scientist, I have a keen interest in the natural world and believe strongly in the role landscape-scale research has to play in maintaining the viability of ecosystems increasingly impacted by development and environmental change. I am particularly interested in how dynamic remote sensing datasets and network analysis can be used to study landscape connectivity through time and across large spatial extents, potentially providing a powerful and efficient mechanism for prioritising conservation within highly modified and increasingly contested landscapes.
Robbi's research focuses on modelling ecological connectivity between surface water habitats of the Murray-Darling Basin, one of the largest semi-arid agricultural basins in the world (> 1 million km2) and home to many of Australia's most significant freshwater ecosystems. Robbi uses graph theory network modelling to analyse connectivity, an advanced statistical framework which has recently seen a rapid uptake for analysing connectivity in terrestrial, marine and surface water systems. By combining graph theory modelling with over 25 years of newly available high-resolution remotely sensed surface-water datasets, this work will attempt to characterise spatiotemporal connectivity dynamics across the Murray-Darling at seasonal, yearly and decadal scales. It is anticipated the results of this research will contribute to current understanding of how habitat network structure, landscape conditions and dynamic events such as flooding combine to influence connectivity across space and time, and ultimately assist in prioritising critical surface water habitats for conservation (e.g. Figure 1).
Figure 1 (based on data from Bishop-Taylor et al. 2017): The distribution of top-ranked surface water habitats for facilitating landscape connectivity across Australia's Murray-Darling Basin between 1986 and 2011. Top-ranked "stepping-stones" (left) are habitats that support long-distance dispersal and gene flow for water dependent organisms, particularly during wet periods (i.e. 2010-2011 La Nina Floods) when newly flooded terrain can significantly improve connectivity through normally fragmented surface-water networks. Top-ranked "hub" habitats (right) represent highly connected habitats that support dispersal between clusters of neighbouring surface-water bodies, and which can potentially serve as important refugia during periods of drought (i.e. the 1997-2009 Millenium Drought).
