Effects of sampling standardization on estimates of Phanerozoic marine diversificationJ Alroy
National Center for Ecological Analysis and Synthesis, University of California, Santa Barbara, CA 93101 3351, USA
Proc Natl Acad Sci U S A 98:6261-6. 2001..However, such factors as the current emphasis in the database on North America and Europe still obscure our view of the global history of marine biodiversity. These limitations will be addressed as the database and methods are refined...
Colloquium paper: dynamics of origination and extinction in the marine fossil recordJohn Alroy
National Center for Ecological Analysis and Synthesis, University of California, 735 State Street, Santa Barbara, CA 93101, USA
Proc Natl Acad Sci U S A 105:11536-42. 2008..Furthermore, the lack of any significant autocorrelation in the data is inconsistent with macroevolutionary theories of periodicity or self-organized criticality...
Phanerozoic trends in the global diversity of marine invertebratesJohn Alroy
National Center for Ecological Analysis and Synthesis, University of California Santa Barbara, 735 State Street, Santa Barbara, CA 93101, USA
Science 321:97-100. 2008..The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic...
Cenozoic bolide impacts and biotic change in North American mammalsJohn Alroy
National Center for Analysis and Synthesis, University of California, Santa Barbara, California 93101, USA
Astrobiology 3:119-32. 2003....
The fossil record of North American mammals: evidence for a Paleocene evolutionary radiationJ Alroy
Department of Paleobiology, Smithsonian Institution, MRC 121, Washington, D C 20560, USA
Syst Biol 48:107-18. 1999..The fact that there was an early Cenozoic mammalian radiation is entirely compatible with the existence of a few Cretaceous splits among modern mammal lineages...
How many named species are valid?John Alroy
National Center for Ecological Analysis and Synthesis, University of California, Santa Barbara, CA 93101, USA
Proc Natl Acad Sci U S A 99:3706-11. 2002..If so, then current estimates of total global diversity could be revised downwards to as low as 3.5-10.5 million species...
A multispecies overkill simulation of the end-Pleistocene megafaunal mass extinctionJ Alroy
National Center for Ecological Analysis and Synthesis, University of California, 735 State Street, Suite 300, Santa Barbara, CA 93101, USA
Science 292:1893-6. 2001..Results are robust to variation in unconstrained parameters. This fully mechanistic model accounts for megafaunal extinction without invoking climate change and secondary ecological effects...
Statistical independence of escalatory ecological trends in Phanerozoic marine invertebratesJoshua S Madin
National Center for Ecological Analysis and Synthesis, University of California, Santa Barbara, CA 93101, USA
Science 312:897-900. 2006..We also find that taxonomic richness and occurrence data are cross-correlated, which justifies the traditional use of one as a proxy of the other...
Mammalian dispersal at the Paleocene/Eocene boundaryGabriel J Bowen
Department of Earth Sciences, University of California, Santa Cruz, CA 95064, USA
Science 295:2062-5. 2002..These results are consistent with Asia being a center for early mammalian origination...
The shifting balance of diversity among major marine animal groupsJ Alroy
Paleobiology Database, University of California, 735 State Street, Santa Barbara, CA 93101, USA
Science 329:1191-4. 2010..The current global crisis may therefore permanently alter the biosphere's taxonomic composition by changing the rules of evolution...
Similarity of mammalian body size across the taxonomic hierarchy and across space and timeFelisa A Smith
National Center for Ecological Analysis and Synthesis, Working Group on Body Size in Ecology and Paleoecology, Santa Barbara, California 93101 5504, USA
Am Nat 163:672-91. 2004..Lineages have diversified in size to exploit environmental opportunities but only within limits set by allometric, ecological, and evolutionary constraints...
