Professor Krebs' major contributions have been in population dynamics of small mammals, especially of sub-Arctic Canada. He pioneered experimental methods that demonstrated the importance of dispersal in populations of meadow voles, mice and lemmings. His textbook Ecology has been the standard work in North America since 1994. He was Chief of CSIRO Wildlife Research (1982-84) and, since 1993, has been an active participant and senior adviser on the Ecology program of the Vertebrate Biocontrol CRC and its successor the Pest Animal CRC. He was a McMaster Fellow (1992-3), a Commonwealth Fellow (1997) and a Visiting Fellow in CSIRO during 1999-2000.

Professor Joseph Connell has been a major international figure in ecology for the past five decades. His PhD research began the field of experimental marine ecology and has stimulated hundreds of experimental studies that have explored the physical and biological determinants of the distribution and abundance of species. More recently, Connell has focussed on the important question of the determinants of biodiversity, particularly in Australian coral reefs and rainforests. He has made an enormous contribution to Australian science and to the research groups and many Australian researchers with whom he has interacted. Connell has also made major contributions to theoretical aspects of ecology, and to important practical applications of ecological theory. In 1985, he was awarded the prestigious Eminent Ecologists award of the Ecological Society of America. Five of Connell's publications, have been designated by Current Contents as "Citation Classics", reflecting his profound influence on the field of ecology.

Professor Rolf Zinkernagel shared the 1996 Nobel Prize for Medicine with Professor Peter Doherty, FAA, FRS, for the seminal discovery of the phenomenon of "MHC restriction". The original work was carried out exclusively in the John Curtin School of Medical Research at ANU between 1973 and 1975. The significance of the discovery is three fold: first it solved the middle of the function of the major histocompatibility gene complex (MHC); secondly, it provided a basis for the mechanisms whereby the immune system distinguishes between self and foreign antigens; thirdly, it set the stage for much of the subsequent work on pathogenesis of autoimmune disease, organ transplantation and design of vaccines against microorganisms and tumours.

Sir Michael Atiyah is one of the great mathematicians of this century. He received the Fields Medal in 1966 for his work on what is now known as the Atiyah - Singer index theorem. This is a very deep result relating the number of solutions of a partial differential coration to the topology of the underlying problem. Atiyah has a large number of Australian Ph.D. student and has collaborative links with Australian mathematicians. He is currently president of the Royal Society, Master of Trinity College Cambridge and Director of the Isaac Newton Institute.

In 1983 Vaughan Jones made a startling discovery in the theory of von Neumann algebras which has had a profound effect on such disparate fields as knot theory, statistical mechanics, quantum field theory and the prediction of DNA configurations in certain biological interactions. For this work Jones was awarded the 1990 Fields Medal. Jones is a regular visitor to Australia and collaborates with several with several Australians.

Professor Batchelor is an Australian by birth and early training who has spent most of his career at the University of Cambridge. There he built up a notable Department which has attracted successive generations of students and postdoctoral workers from Australia, and those who have returned to senior positions here acknowledge his strong and continuing influence on the development of applied mathematics and fluid mechanics in this country and around the world. His personal research and more general contributions to his field have been widely recognised by the award of a Royal Medal of the Royal Society and many other international awards, elections and honorary degrees.

Peter Raven is a distinguished plant taxonomist whose research on several groups of plants, on biogeography and on rainforests has many connections with Australia. His monograph on the genus Epilobium in Australasia was described as "definitive in every conceivable way". In 1965 with Paul Ehrlich he developed the concept of "co-evolution" from their work on butterflies and plants. He subsequently pioneered work on folk taxonomy, of the Tzeltal people of Mexico. His Lemberg Fellowship lectures on "Australasian biogeography and continental drift" recognised his influence in that area. Recently he has been active as a referee of the Australian Heritage Commission on behalf of conservation of tropical rainforests in Queensland.
