Summary

Potential effects of climate change have become a central consideration in managing aquatic populations, both for exploitation and/or conservation of marine and freshwater taxa. While specific effects of climate change are going to be expressed differently among inland and marine species, in general we are now seeing an increasing number of documented instances of: i) changes to the abundance and recruitment; ii) shifts in species ranges; iii) changes to dispersal opportunities and timing of migrations; iv) novel species interactions, etc.  Predicting population dynamics in the face of climate change is problematic due to the intrinsic variation in species-specific life history traits as well as the underlying architecture of respective genomes. A genomics approach for investigating the basis for adaptive response to the effects of climatic fluctuations now offers opportunities to gain insight into the short-medium term persistence of populations.

 

Brief biography

David Hurwood is a Senior Lecturer in the Science and Engineering Faculty at the Queensland University of Technology, Australia. He completed his PhD in 2001 at Griffith University in Molecular Ecology and has subsequently spent the last 15 years developing population genetics, research in aquatic systems, applying these approaches to wild and cultured populations of various fish and crustacean taxa. In recent years, this research has expanded to incorporate genomic technologies. Among other projects, our research group is currently applying a genomics approach to: i) improve growth and productivity in aquaculture species; ii) investigate the genetic basis for adaptation of crustaceans to freshwater from a marine ancestry; iii) understanding species and speciation.
