Summary of career
Ralph Slatyer was born in Melbourne in 1929. He was educated at the University of Western Australia where he received a BSc in 1951, an MSc in 1955 and a DSc in 1960. His studies were in agriculture, particularly in looking at the factors linking plant and water relationships to climatology.
In 1951 he began work as a research scientist with the CSIRO in what became the Division of Land Research. He was an ecoclimatologist, trying to predict the length of the growing season for introduced crops and pastures using climatic information, soil characteristics and other physical factors. He was part of a team that investigated the potential for agriculture in the north of Australia. From 1966-1967 he was the Associate Chief of the Division.
In 1967 Slatyer became the Foundation Professor in Environmental Biology in the Research School of Biological Sciences (RSBS) at the Australian National University (ANU). His research at this time included how plants differ from each other in photosynthesis and transpiration rates. It was here that he began to look at ecological succession in disturbed ecosystems. Also while at the ANU he served as the Director of RSBS (1984-89). On his retirement in 1993 he became Distinguished Scholar in Residence at RSBS.
