How nature works: The science of self-organized criticality
Bak wants the reader to grasp the basic logic of his arguments; only rarely does he try to persuade with flights of poetic language or brute intellectual authority. Expand

Mass Extinctions in the Marine Fossil Record
A new compilation of fossil data on invertebrate and vertebrate families indicates that four mass extinctions in the marine realm are statistically distinct from background extinction levels. TheseExpand

Mammalian Evolution and the Great American Interchange
A reciprocal and apparently symmetrical interchange of land mammals between North and South America began about 3 million years ago, after the appearance of the Panamanian land bridge. The number ofExpand

Measurement of faunal similarity in paleontology
A probabilistic index of faunal similarity is proposed which compares the number of taxa common to two faunas with the number that would be expected to be in common if the taxa were distributedExpand

Geometric analysis of shell coiling; general problems
Among the shells of invertebrates that exhibit spiral growth, differences in form can be expressed by differences in geometric parameters. If three parameters are considered at a time, the spectrumExpand

Taxonomic diversity estimation using rarefaction
Benthic ecologists have successfully applied rarefaction techniques to the problem of compensating for the effect of sample size on apparent species diversity (= species richness). The same methodExpand

Geometric analysis of shell coiling; coiling in ammonoids
Ammonoids occupy only a small part of the geometric range available to spirally coiled organisms. Measurements of 405 genera are used to characterize the range of variation in spiral form of normalExpand

Effects of sampling standardization on estimates of Phanerozoic marine diversification
Global diversity curves reflect more than just the number of taxa that have existed through time: they also mirror variation in the nature of the fossil record and the way the record is reported.Expand

Stochastic Models of Phylogeny and the Evolution of Diversity
Equilibrium models in population biology have demonstrated that accurate predictions of species diversity can be made without reference to particular taxa. We have extended the use of equilibriumExpand
