The species concept as an emergent property of population biologyMichael W Hart
Department of Biological Sciences, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
Evolution 65:613-6. 2011....
Morphological and genetic variation indicate cryptic species within Lamarck's little sea star, Parvulastra (=Patiriella) exiguaMichael W Hart
Department of Biological Sciences, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
Biol Bull 210:158-67. 2006..Both modes of reproduction have broad geographic ranges. These results are consistent with previously published genetic data that indicate multiple species in African and island (but not Australian) populations...
Things fall apart: biological species form unconnected parsimony networksMichael W Hart
Department of Biological Sciences, Simon Fraser University, 8888 University Drive, Burnaby, British Columbia, Canada
Biol Lett 3:509-12. 2007..Departures from these patterns are usually consistent with hybridization or cryptic species diversity...- Discordant distribution of populations and genetic variation in a sea star with high dispersal potentialCarson C Keever
Department of Biological Sciences, Simon Fraser University, Burnaby, British Columbia V5A 1S6, Canada
Evolution 63:3214-27. 2009.... - Discovery and cross-amplification of microsatellite polymorphisms in asterinid sea starsCarson C Keever
Department of Biological Sciences, Simon Fraser University, Burnaby, British Columbia, Canada
Biol Bull 215:164-72. 2008..At 12 loci in two species, we found 1-10 alleles per microsatellite, with a broad range of inbreeding coefficients. Measures of polymorphism were negatively correlated with the extent of cross-amplification... - Caterpillars did not evolve from onychophorans by hybridogenesisMichael W Hart
Department of Biological Sciences, Simon Fraser University, Burnaby, BC, Canada
Proc Natl Acad Sci U S A 106:19906-9. 2009.... - Low rates of bindin codon evolution in lecithotrophic Heliocidaris sea urchinsMichael W Hart
Biological Sciences, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
Evolution 66:1709-21. 2012..Bindin evolution is not driven by egg size variation among Heliocidaris species, but may be more consistent with an alternative mechanism based on the effects of high or low spatial density of conspecific mates... - Something for nothing? Reconstruction of ancestral character states in asterinid sea star developmentCarson C Keever
Department of Biological Sciences, Simon Fraser University, Burnaby, BC, Canada
Evol Dev 10:62-73. 2008..We suggest caution in applying ancestral state reconstructions in the absence of an independently corroborated model of character evolution, and highlight the need for such modeling in evolutionary developmental biology... - Sea star populations diverge by positive selection at a sperm-egg compatibility locusJennifer M Sunday
Department of Biological Sciences, Simon Fraser University Burnaby, British Columbia, Canada
Ecol Evol 3:640-54. 2013..These findings provide evidence of population-divergent positive selection in a fertilization compatibility locus, and suggest that sexual selection can lead to reproductive divergence between conspecific marine populations... - Quantifying rates of evolutionary adaptation in response to ocean acidificationJennifer M Sunday
Department of Biological Sciences, Simon Fraser University, Burnaby, British Columbia, Canada
PLoS ONE 6:e22881. 2011..Our comparisons suggest that information on genetic variation, phenotypic variation, and key demographic parameters, may lend valuable insight into relative evolutionary potentials across a large number of species... - Bindin from a sea starSusana Patiño
Department of Biological Sciences, Simon Fraser University, Burnaby, BC, Canada V5A 1S6
Evol Dev 11:376-81. 2009.... - It's about time: divergence, demography, and the evolution of developmental modes in marine invertebratesMichael W Hart
Department of Biological Sciences, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
Integr Comp Biol 50:643-61. 2010.... - Introgression versus immigration in hybridizing high-dispersal echinodermsFiona M Harper
Department of Biology, Dalhousie University, Halifax, NS, Canada
Evolution 61:2410-8. 2007..We conclude that, in these cases at least, larvae are more effective than gametes as vectors of gene flow... - Colonization, dispersal, and hybridization influence phylogeography of North Atlantic sea urchins (Strongylocentrotus droebachiensis)Jason A Addison
Department of Biology, Dalhousie University, Halifax, Nova Scotia B3H 4J1, Canada
Evolution 59:532-43. 2005..These differences across marker types might have several biological or methodological causes, and they suggest caution in interpretation of the results from a single locus or class of markers... - Mitochondrial DNA phylogeny and rates of larval evolution in Macrophiothrix brittlestarsMichael W Hart
Department of Biology, Dalhousie University, 1355 Oxford Street, Halifax, NS, Canada B3H 4J1
Mol Phylogenet Evol 34:438-47. 2005..In support of this hypothesis, branch lengths for intermediate forms were short relative to those for species with highly derived non-feeding forms. The absolute rarity of such forms makes robust tests of the hypothesis difficult... - Reproduction and larval morphology of broadcasting and viviparous species in the Cryptasterina species complexMaria Byrne
Department of Anatomy and Histology, F13, University of Sydney, NSW 2006, Australia
Biol Bull 205:285-94. 2003.... - Life history evolution and comparative developmental biology of echinodermsMichael W Hart
Department of Biology, Dalhousie University, Halifax, Canada
Evol Dev 4:62-71. 2002..Both sets of topics provide opportunities for interaction and collaboration...
