The experimental, analytical and integrative research achievements of the author,
relating to the study of plant functioning and dynamics of plant populations and
communities in semi-arid landscapes of eastern Australia and the responses to the
stresses of drought, fire and grazing, are described. These achievements occurred during
a period when scientific knowledge on the functioning and dysfunctioning of ecological
communities in arid and semi-arid pastoral lands were required for the development of
new managements that sustained natural resources in these water-limited environments.
The research described addresses the principle goals of the author, namely to (i)
elucidate physiological and demographic responses to climate variability and
interactions with the stresses of grazing and fire, and (ii) to use the knowledge to
develop new grazing and fire managements for sustaining pastoral businesses and the
natural resources on which they depend, in semi-arid pastoral Australia.
In this thesis, the research achievements of the author, the consequent
publications, and the recognition of this research, are summarised in the Preface
(Section 1). Following the author's curriculum vitae (Section 2), and full list of
. publications (Section 3 ), a detailed description of the author's research is given in
Section 4, which comprises 40 selected publications in refereed journals and books,
totalling some 482 pages. These selected publications address the research theme
defined by the thesis title Dynamics of plant processes and populations in semi-arid
Australia and the influences of drought, grazing and fire, and cover the period 1970-
2002, during the candidates' research programs with the Commonwealth Scientific and
Industrial Research Organisation at Deniliquin and Canberra, Australia.
