- To succeed globally, disperse locally: effects of local pollen and seed dispersal on tetraploid establishmentE J Baack
Center for Population Biology, University of California, One Shields Avenue, Davis, CA 95616, USA
Heredity (Edinb) 94:538-46. 2005..With short-distance seed and pollen dispersal, polyploid speciation should be possible in the absence of ecological differentiation or recurrent polyploid formation through unreduced gametes...

Ecology 87:2736-45. 2006..tricolor in this population. Fine-scaled ecological heterogeneity and heterogeneous boundary conditions likely play important roles in limiting adaptation and subsequent range expansion at population boundaries in G. tricolor...
- Engineered crops: transgenes go wildEric J Baack
Department of Biology, Indiana University, 1001 E 3rd St, Bloomington, Indiana 47405, USA
Curr Biol 16:R583-4. 2006..Genetically modified Agrostis stolonifera has escaped from cultivation. For the first time, a herbicide-resistant perennial weed has established itself in wild populations...
- Ecological factors influencing tetraploid speciation in snow buttercups (Ranunculus Adoneus): niche differentiation and tetraploid establishmentEric J Baack
Center for Population Biology, One Shields Avenue, University of California, Davis, California 95616, USA
Evolution 59:1936-44. 2005..At the seed and seedling stages, neither niche differentiation nor tetraploid competitive superiority appears sufficient to explain neotetraploid success in the presence of their diploid progenitors...
- Hybridization and genome size evolution: timing and magnitude of nuclear DNA content increases in Helianthus homoploid hybrid speciesEric J Baack
Department of Biology, Indiana University, 1001 East Third Street, Bloomington, IN 47405, USA
New Phytol 167:623-30. 2005..In summary, hybridization by itself does not lead to increased nuclear DNA content in Helianthus, and the evolutionary forces responsible for the repeated increases in DNA content seen in the hybrid-derived species remain mysterious...

Department of Biology, Indiana University, Bloomington, Indiana 47405, USA
Nature 440:524-7. 2006..Contrary to conventional wisdom, plant species are more likely than animal species to represent reproductively independent lineages...

Department of Botany, University of British Columbia, 6270 W University Blvd, Vancouver, BC, Canada V6T 1Z4
Mol Ecol 17:666-77. 2008..These results indicate that crop trait values and alleles may sometimes be favoured in a noncrop environment and across broad geographical regions...

Department of Botany, University of British Columbia, 3529 6270 University Blvd, Vancouver, BC, Canada V6T1Z4
Ecol Lett 11:1082-91. 2008..Our results suggest a common means by which ecological selection may contribute to speciation and have significant implications for the persistence of hybridizing species...
