Publications
The modulation of DNA content: proximate causes and ultimate consequencesT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario N1G 2W1
Genome Res 9:317-24. 1999..These abrupt shifts have broad effects on phenotypic attributes at both cellular and organismal levels and may play an important role in explaining episodes of rapid-or even saltational-character state evolution...
Evolutionary implications of the relationship between genome size and body size in flatworms and copepodsT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario, Canada N1G 2W1
Heredity (Edinb) 84:201-8. 2000..Genome sizes appear to vary in a discontinuous fashion among congeneric species in both groups, indicating that such changes have occurred rapidly, and with potentially profound effects on important morphological characters...
Nucleotypic effects without nuclei: genome size and erythrocyte size in mammalsT R Gregory
Department of Zoology, University of Guelph, ON, Canada
Genome 43:895-901. 2000..In evolutionary terms, they provide insights into the constraints on genome expansion among mammals and are therefore of interest in attempts to solve the long-standing C-value enigma (also known as the C-value paradox)...
The bigger the C-value, the larger the cell: genome size and red blood cell size in vertebratesT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario N1G 2W1, Canada
Blood Cells Mol Dis 27:830-43. 2001..The present article describes the correlation between genome size and RBC size in vertebrates and discusses some of the cytological, physiological, and evolutionary implications of this relationship...
Coincidence, coevolution, or causation? DNA content, cell size, and the C-value enigmaT R Gregory
Department of Zoology, University of Guelph, Ontario, Canada
Biol Rev Camb Philos Soc 76:65-101. 2001..Finally, some evolutionary implications of genome size diversity are considered, and a broadening of the traditional 'biological hierarchy' is recommended...
An expansion of the genome size dataset for the insect order Hymenoptera, with a first test of parasitism and eusociality as possible constraintsA M Ardila-Garcia
Department of Integrative Biology, University of Guelph, Guelph, ON, Canada
Insect Mol Biol 19:337-46. 2010..The data provided here can be used to guide future research aimed at understanding the evolution of large-scale genomic properties in this order...
Genome size diversity in the family DrosophilidaeT R Gregory
Department of Integrative Biology, University of Guelph, Guelph, Ontario, Canada
Heredity (Edinb) 101:228-38. 2008..These findings may provide some explanation for the streamlined genomes found in these insects, and complement recent work demonstrating possible selective constraints on further deletion of noncoding DNA...
Genome sizes of spidersT R Gregory
Department of Zoology, University of Guelph, Guelph, ON N1G 2W1 Canada
J Hered 94:285-90. 2003..No clear-cut patterns of variation were detectable even with this relatively large data set, but some interesting avenues for future research have been illuminated by this preliminary survey...
