Abstract:
The aim of the thesis is the investigation, initially in ecological terms and subsequently on a regional basis, of a savanna environment in British Guiana. In the examination of the savanna ecosystem, attention was focused initially on the concept of the ecoclimate. This concept provides a means of expressing the influence on plant growth, in terms of moisture availability, of many elements in the ecosystem, principally climate, relief, drainage and the physical condition of the soil. Of the factors examined, climatic fluctuations during the last 12,000 years were considered the most significant, and an attempt was made to relate these to the evolution of the present savanna landscape. In addition to considerations of climatic, pedologic and anthropic factors in the ecosystem, attention was paid to correlations that have been drawn, by some writers, between older landscape surfaces and savannas. Such an interpretation represents a broader, regional approach to a problem that has, in the present thesis, been given more detailed ecological treatment.
