Scientists studying molecular changes in penguins


Sydney, Australia: A joint team of Indian and Australian scientists is studying molecular changes in Adelie – a penguin species commonly found along the entire Antarctic coast, triggered by global warming. Australian team leader David Lambert is collaborating with Siva Swaminathan, who leads the Indian side, under the aegis of the Australia-India Strategic Research Fund (AISRF).

Arnold Dekker from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), said researchers use satellite-based observation of earth’s coasts and oceans to monitor ocean colour, which arises from changes in algae, suspended and dissolved organic material. “Ocean colour helps us understand the interactions between aquatic ecosystems, climatic factors and human impacts,” he added.

The experts during a workshop agreed that understanding these interactions can help in forming better policies for protecting coastal reefs and ecosystems from potentially harmful disturbances caused by human activity and environmental stresses.

The experts are also looking at the larger issue of whether climate change drives evolution.
