The Unified Neutral Theory of Biodiversity and Biogeography (MPB-32) (Monographs in Population Biology)

Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context.
Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales.
Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.

Architect: James Hubbell
Location: Santa Ysabel, CA

James Hubbell has been building and adding to his home on a hilltop outside of San Diego, CA for over 30 years. It's clearly inspired by Gaudi (and walking the grounds feels a lot like a mini Park Guell), among other influences. But Hubbell is a master of organic architecture and walking through his estate is a rare treat. It's open to the public every year on Fathers' Day.

This compound was almost destroyed in the Cedar Fire of 2003, but has now been almost entirely rebuilt.

Behind the Hubbell Trading post was a facinating area with an old house, a couple of wagons, and a lot of old farm equipment. I am not really up on my moder farm equipment and really do not know much about old farm equipment. But I knew someone would know. Thanks Ula for letting me know that it is a harrow.
