Latitudinal Gene Drift in Ross Sea Organisms
This project was interested in the mechanisms by which about 100 or so notothenioid fish species have radiated in about 15 to 20 million years, apparently from one ancestral species. To do this samples were taken from populations of cosmopolitan notothenioid species from a number of sites. The aim was to collect sufficient number of fish from each site and for each species to allow assessment of differences both within and between populations and sites.

Lipid Metabolism and Adaptation in Antarctic Fish
This research concentrates primarily on the adaptation of polar organisms to their environment - covering past adaptation and the present capacity to cope with future change. In particular, this work related to Key Questions 1, 2, 3 and 6. Victoria is interested in Antarctic fish and how they function. The area of biology is known as functional genomics- a combination of molecular biology, evolutionary biology and biochemistry. This research examines molecular and physiological differences between organisms and also uses these differences to learn more about how animals function in their environment (envirogenomics).

Latitudinal Patterns in the Abundance of Ross Sea Meroplankton
The pelagic community of the Ross Sea consists of a permanent component (= holoplankton), exemplified by animals such as copepods, and a temporary component which is primarily made up from the larval stages of benthic marine invertebrates and fish (= the meroplankton). To date little attention has been paid to the distribution and abundance patterns of the meroplankton, hampered in part by the inability to identify these larval “types” to the species-level. Detailed studies of the meroplankton community at a range of latitudes were undertaken involving daily quantification of the distribution and abundance of the common larval forms identified.

Antarctic Sea Ice, Algal Productivity and Global Climate Change
This study aimed to provide ground truth data of total primary productivity and biodiversity and aimed to be the first to assess the effect of global climate change on primary productivity in Antarctic coastal ecosystems. The relationship between the extent of ice cover and total primary production along an extensive north-south transect of the western coast of the Ross Sea, was used to predict future scenarios of reduced ice at sites further south.
