Bio Geography

Biogeography is the science that attempts to document and understand spatial patterns of biodiversity. It is the study of distributions of organisms, both past and present, and of related patterns of variation over the earth in the numbers and kinds of living things. In essence we are asking: How are organisms distributed over the surface of he earth and over the history of the earth? (click here for more)


Life is amazing. Even the smallest bacterium is far more complex in its structure and function than any known physical system. The largest, most complex organisms, large mammals and giant trees, weigh more than 21 orders of magnitude more than the simplest microbes, yet they use basically the same molecular structures and biochemical pathways to sustain and reproduce themselves.

MacroecologyMacroecology is concerned with the statistical distributions of variables among large numbers of comparable ecological "particles." Usually these particles are either many individual organisms within species populations, or many species within local, regional or continental biotas. The individuals and species are not exactly identical; they vary in their characteristics. Macroecology seeks to discover, describe and explain the patterns of variation. (click here for more)


Underlying the diversity of life and the complexity of ecology is order that reflects the operation of fundamental physical and biological processes. Scaling relationships are emergent quantitative features of biodiversity. Some of them appear to be universal, occurring in virtually all taxa of organisms and kinds of environments. They are patterns of structure or dynamics that are self-similar or fractal-like over many orders of magnitude. (click here for more)
