Biography and Research Interests
Doctor of Philosophy (Marine Ecology), 2003 – Duke University, USA
Bachelors or Science (Biology), 1993 – University of California, San Diego, USA
My general interests lie in the area of fish population ecology and my research has focused on the behavior and demographics of individual fish populations as well as the large scale connectivity between these populations. The small scale studies are typically conducted on SCUBA or snorkel and employ tools such as tagging, mapping and standard underwater census and behavioural observation techniques. These studies have been conducted in a variety of locations including the Florida Keys (USA), Lee Stocking Island (Bahamas), and One Tree Island (Australia).
My interest in the larger scale dynamics of reef fish involves understanding the mechanisms and consequences of metapopulation, and specifically source-sink, dynamics in these systems. While the spatial structure of these systems (distinct areas of occupied habitat) and the connectivity within them (larval exchange between areas) lend themselves nicely to descriptions invoking metapopulation theory, our current understanding of system dynamics is quite low. My work on this topic has run the spectrum from the highly theoretical exercise of creating conceptual and analytical models to allow for the application of metapopulation theory to marine systems in general to the much more applied topic of using metapopulation theory for citing marine reserves and creating effective, biologically interacting reserve networks. I use individually-based, stage-structured spatially realistic computer simulation models to study the impact of variations in habitat quality and network connectivity on system dynamics and specifically source-sink structure.
Current Research Themes
Tropical temperate connectivity of marine fish populations and the potential for range shifts due to global climate change
[Collaborators: David Booth, UTS]
This project studies the spatial and temporal patterns of transport and settlement of tropical vagrant fish species into subtropical regions and evaluates the potential for large scale range shifts of these species as the oceans off of SE Australia continue to warm. We are combining life history information obtained from otolith and lipid analysis with properties of transport obtained from Lagrangian biophysical dispersal modeling to better understand connectivity with upstream reefs and alterations to these patterns that may result from large-scale climate change such as ENSO and global warming. Such climate change has the potential to dramatically alter distributional patterns near the edge of the species range and in so doing can have very interesting metapopulation-level ramifications.
Post-settlement demographics of reef fishes
Newly settled reef fish typically experience a very high rate of mortality due to predation and competition. Recent work has demonstrated that the condition of newly settled fish, as expressed by their lipid concentration, can affect their susceptibility to predation in both lab and field experiments. In this research theme I use a variety of lab and field studies at locations on the Great Barrier Reef (including One Tree Island) to look at mechanism by which fish conditional state, behaviour and performance interact with environment (biological and physical) to determine post-settlement success.
Connectivity and metapopulation modeling of coastal reef habitats
[Collaborators: NSW Dept. of Environment and Climate Change, Moninya Roughan, UNSW; Claire Paris, RSMAS]
This research theme builds upon my previous work modeling source-sink population structure by applying these tools to a variety of systems. Currently I am working on modeling the source-sink structure of the Florida Keys reef system in the United States and looking at connectivity patters along the SE coast of Australia. This work is built around the same biophysical dispersal modeling mentioned above and in the case of source-sink structure, combines this with benthic habitat information.
