This course focuses on the distribution of organisms, and examines the dynamics and assemblages of organisms. In this context, the ecosphere or the interaction between the living and non-living entities is central. Thus historical distributions, succession, and population dynamics are studied. The course also covers spatial aspects related to biodiversity, and pays attention to the influence of man as a biogeography agent. Biogeography methods will be introduced as part of the course. This course also includes some field work.

Course topics: Introduction; The ecosphere; Historical distribution; Quaternary biogeography; Major biomes; Island biogeography; Biodiversity; Man as an agent; and Biogeography methods. 

This course provides the students with a substantial understanding of population dynamics, and of significant population issues that all geographers need to be familiar with. This lecture program will trace the growth of Population Geography, introduce conceptual developments in demographic studies and population dynamics, and will lead on to the study of the more important population issues in developing countries with special emphasis on Sri Lanka. This course will provide a foundation for those who wish to follow population related study areas in third and fourth years.

Course topics: The Nature of Population Geography; Theories of population; Measurements of population; Population composition; Migration; Population trends; and Projections and policies.
