- Abstract:
- Transport of organisms by passive and active processes are fundamental to an understanding of colonization, evolution and biodiversity. The research will examine the influence of oceanographic processes, bathymetry and life history variation on dispersal and gene flow in two Antarctic fishes that differ in the distribution of eggs and larvae and longevity. Ocean general circulation models such as the Ocean Circulation and Climate Advanced Model (OCCAM) will predict transport speed and direction of planktonic fish eggs and larvae spawned at different locations around Antarctica. A high resolution oceanographic model of the shelf processes around one region will be used to examine the drift and retention of early life history stages and shelf-open ocean transport such that the behaviour and life history can be incorporated into the wider ocean circulation patterns. Molecular markers (microsatellites) will be used to analyse population structure at both circumpolar and regional geographic scales, which will be compared with predictions from the oceanographic model. Additionally, mtDNA analysis will be used to examine putative colonisation patterns around the Southern Ocean. Information will be obtained concerning the impact of the topographic and oceanographic regime on dispersive phases and adult migration, thereby providing novel insights into the nature of biological and environmental constraints on dispersal and gene flow.
