 Global biodiversity and the ancient carbon cycleD H Rothman
Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Proc Natl Acad Sci U S A 98:430510. 2001..As a consequence, the paleontological record of biodiversity provides an indirect estimate of the fluctuations of ancient CO(2) levels...  Dynamics of the Neoproterozoic carbon cycleDaniel H Rothman
Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Proc Natl Acad Sci U S A 100:81249. 2003..The terminal event, at the ProterozoicCambrian boundary, signals the final diminution of the reservoir, a process that was likely initiated by evolutionary innovations that increased export of organic matter to the deep sea...  Reexamination of the "3/4law" of metabolismP S Dodds
Department of Mathematics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
J Theor Biol 209:927. 2001..We find that present theories for alpha = 3/4 require assumptions that render them unconvincing for rejecting the null hypothesis that alpha = 2/3...  Geometry of river networks. I. Scaling, fluctuations, and deviationsP S Dodds
Department of Mathematics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Phys Rev E Stat Nonlin Soft Matter Phys 63:016115. 2001..The extent of approximate scaling is significantly restricted by these deviations, and will not be improved by increases in network resolution...  Geometry of river networks. II. Distributions of component size and numberP S Dodds
Department of Mathematics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Phys Rev E Stat Nonlin Soft Matter Phys 63:016116. 2001..The calculations identify a single length scale as a measure of size fluctuations in network components. This article is the second in a series of three addressing the geometry of river networks...  Geometry of river networks. III. Characterization of component connectivityP S Dodds
Department of Mathematics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Phys Rev E Stat Nonlin Soft Matter Phys 63:016117. 2001..Fluctuations in side stream numbers are shown to be a direct result of fluctuations in stream lengths. This is the last paper in a series of three on the geometry of river networks...
