Dr Troy Day is a theoretical evolutionary ecologist at Queen’s University, Kingston, Canada (http://www.mast.queensu.ca/~tday/index.html). His primary research interests are in the evolution of interspecific interactions, particularly between pathogens and their hosts. Many of the modeling approaches we use in the evolution of host-pathogen interactions can be readily applied to symbiotic interactions, however, and that is what brought Troy to coral biology. Troy hopes to use this opportunity to obtain useful feedback and to stimulate interest and potential collaboration on related future projects.
We have been using mathematical models of evolutionary change to better understand the key factors involved in the evolution of bleaching resistance in corals. Our primary focus has been on coral bleaching that occurs as a result of temperature stress. We have been using the models to explore the expected pattern of resistance evolution in response to an increase in average sea temperature, and how this pattern is affected by the biological details of the coral-zooxanthellae interaction. I will present some qualitative results obtained from very simple models of the eco-evolutionary dynamics of this symbiosis.
Scientists say a ‘portfolio’ of protected areas within marine parks such as the Great Barrier Reef can help secure sustainable fish populations. Dr Hugo Harrison from the ARC Centre of Excellen
Scientists have developed a new genetic tool that can help them better understand and ultimately work to save coral reefs. “Surprisingly, we still don’t know how many coral species live on the
A new study suggests ‘dead’ coral rubble can still sustain life, with a large number of tiny animals hidden and living amongst the ruins. While the study does not suggest dead coral has the sam
A new study on coral evolution has found climates similar to what we’re seeing today have previously devastated hard-bodied corals—the architects of coral reefs—while making way for their softer
Abstract: When abundant, seabirds feeding in the open ocean transport large quantities of nutrients onto islands, enhancing the productivity of island fauna and flora. These nutrients can leach int
Abstract: Current-day populations of coral reef fish suffer when exposed acutely to elevated temperatures, but future warming will occur over greater timescales. Recent studies show that developmenta
Abstract: There is often a mismatch between the scales at which ecosystems are threatened by human impacts and those at which management and policy are implemented. Better understanding the scales ov
Abstract: Ocean warming and acidification are challenging the tolerance limits of scleractinian corals. However, beneficial acclimation and stress-hardening via phenotypic plasticity may be pathw
Abstract: Globally, coral reefs are under threat. Unfortunately, the rate of ecosystem degradation often surpasses the rate of generation of knowledge required to support management. Despite the consi
Abstract: Illegal, unreported, and unregulated fishing threatens resource sustainability and equity. A major challenge with such activity is that most fishing vessels do not broadcast their positions
Abstract: Coral reefs are among the most diverse and productive ecosystem's worldwide, but their future is threatened by a host of anthropogenic disturbances. To protect reefs and their services to hu
