- Geographic barriers isolate endemic populations of hyperthermophilic archaeaRachel J Whitaker
Department of Plant and Microbial Biology, University of California, 111 Koshland Hall, Berkeley, CA 94720, USA
Science 301:976-8. 2003..The identification of a biogeographic pattern in the archaeon Sulfolobus challenges the current model of microbial biodiversity in which unrestricted dispersal constrains the development of global species richness...
- Recombination shapes the natural population structure of the hyperthermophilic archaeon Sulfolobus islandicusRachel J Whitaker
Department of Plant and Microbial Biology, University of California, Berkeley, USA
Mol Biol Evol 22:2354-61. 2005..We propose instead that frequent recombination among closely related individuals prevents periodic selection from purging diversity and provides a fundamental cohesive mechanism within this and perhaps other archaeal species...
- Population genomics in natural microbial communitiesRachel J Whitaker
Ecosystem Sciences, 137 Mulford Hall, University of California, Berkeley, CA 94720 3114, USA
Trends Ecol Evol 21:508-16. 2006..We suggest that understanding the evolutionary ecology of natural microbial populations through population-genomic analyses will enhance our understanding of genome evolution across all domains of life...
- Genome dynamics in a natural archaeal populationEric E Allen
Department of Environmental Science, Policy, and Management, University of California, Berkeley, CA 94720, USA
Proc Natl Acad Sci U S A 104:1883-8. 2007..The larger genetic potential of the population relative to individuals within it and the combinatorial process that results in many closely related genome types may provide the basis for adaptation to environmental fluctuations...
- Allopatric origins of microbial speciesRachel J Whitaker
Department of Microbiology, University of Illinois, 601 South Goodwin Avenue, Urbana, IL 61801, USA
Philos Trans R Soc Lond B Biol Sci 361:1975-84. 2006..Investigating these differences in evolutionary mechanisms will greatly enhance interest in, and understanding of, the dynamic processes that create and maintain the vast diversity of the microbial world...
- Microbial biogeography: from taxonomy to traitsJessica L Green
Center for Ecology and Evolutionary Biology, Department of Biology, University of Oregon, Eugene, Oregon 97403, USA
Science 320:1039-43. 2008..We anticipate that as trait-based biogeography continues to evolve, micro- and macroorganisms will be studied in concert, establishing a science that is informed by and relevant to all domains of life...
