Phytoplankton is the basis of the Antarctic food web. The patchy distribution of these algae is thought to be controlled by ocean currents in the Southern Ocean. We will explore how climate change influences the health and distribution of phytoplankton.
Viruses are tiny particles that cannot reproduce by themselves. To reproduce they have to parasitise a bacterial cell, or another organism.
Glaciers are not frozen rivers, but another aquatic ecosystem in the cryosphere. Most life on glaciers occurs in numerous shallow holes called cryoconites as simple microbial communities.
We propose to analyse a unique historical database collected over 17 years from 1956-1972 examining the survival and reproductive success of the endemic royal penguin from Macquarie Island.
Bacteria can respond rapidly to environmental change by acquiring new genes via lateral gene transfer. A DNA element called the integron can capture, mobilise and express genes, thereby playing a role in the transfer process.
A molecular genetic approach will be used to probe the biodiversity and biogeography of invertebrate animals from eastern Antarctica.
The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) aims to manage the harvesting of living resources in the Southern Ocean in a manner that is sustainable to the harvested species, dependent species and ecosystem processes.
The overall objective is to characterize Southern Ocean marine ecosystems, their influence on carbon dioxide exchange with the atmosphere and the deep ocean, and their sensitivity to past and future global change including climate warming, ocean stratification…
