Chrystal Mantyka-Pringle is an Applied Ecologist and Conservation Scientist who specializes on understanding the impacts and interactions of climate change and land-use change on biodiversity and translating the implications of global change into conservation planning. Chrystal achieved a Bachelor of Science with First Class Honours in Marine Biology from James Cook University in Australia. Later she received a PhD in Conservation Biology from the University of Queensland in Australia on the topic of decision making for conserving biodiversity in the face of climate change and land-use change. Chrystal has worked for the Australian Government Department of Environment and Resource Management and the Commonwealth Scientific and Industrial Research Organization (CSIRO) as a Research Projects Officer focused on maintaining and managing water quality and aquatic ecosystem health and minimizing the risk of infestation of invasive species. Chrystal has now joined the U of S and the Global Institute for Water Security in 2014 as a post-doctoral research fellow to develop a decision theory model for examining environmental change in the Canadian River deltas.    

Chrystal’s research interests include:

  • Understanding the interactions between multiple stressors on patterns and processes shaping biodiversity and ecosystem services
  • Bridging science and traditional knowledge for conservation design and planning
  • Identifying spatial priorities for conservation actions, particularly restoration ecology at local, regional and global scales
  • Using expert knowledge and empirical data to make good and adaptive conservation planning decisions
  • Investigating the role of collaboration in conservation, particularly the links between scientists, practitioners,  managers, policy makers and the public in achieving defensible science-based conservation and environment decisions  

Chrystal is an associate member of the Conservation Decisions Team with the CSIRO Ecosystem Sciences in Brisbane, Australia ( She is also a research affiliate with the ARC Centre of Excellence for Environmental Decisions ( and the National Environment Research Program’s Research Hub for Environmental Decisions. These are multi-disciplinary groups with expertise in ecology, systematic conservation planning, priority threat management, artificial intelligence, and decision theory.

Luis Morales MarinNHRC

Karl-Erich Lindenschmidt,
Howard Wheater

Luis studied Civil Engineering in the Colombian School of Engineering and obtained an MSc in Water Resources at the National University of Colombia in Bogota. After receiving a scholarship he pursued his PhD studies in Physical Geography at University College London (UCL), United Kingdom working on sediment transport and hydrodynamics modeling in lakes at the Coastal and Estuaries Research Unit (CERU).

Luis has worked for consulting companies in Colombia in the design and construction of hydraulic structures. His research is focused on the study and modelling of complex physical processes associated with hydrology and hydrodynamics in lakes, rivers and estuaries. He is particularly interested in the study of the hydrodynamics and its effects on erosion, transport and deposition of sediments and nutrients in catchments. His research also focuses on the understanding of the processes derived from the interaction between climate forcing and rainfall-runoff events.

Luis is currently working on water quality modelling in the South-Saskatchewan River Basin using the SPARROW model under the supervision of Drs. Karl-Erich Lindenschmidt and Howard Wheater.
