"...This text has been arranged with the goal of developing a comprehensive understanding of the contemporary geographical patterns of life on the Earth. The topics of the chapters are vantage points - both close-up and distant, and over short and long time periods - which assist in explaining the processes involved in the arrangement of life on the Earth. Each major part of the text represents one of four major themes of biogeography and examines the problem of patterns of life from different conceptual perspectives. Each chapter reveals an ingredient of the overall processes which influence the Earth's pattern of life. Together the chapters present a tapestry of concepts which describe many aspects of the diversity and many details of processes and conditions for patterns of life. The combination of these concepts yields an ever broadening mosaic of patterns. Each place on the Earth is unique because of its particular combination of processes and conditions. At each place, the patterns of life are assembled for reasons peculiar to that place..." (Howard Walter Mielke)
