Journal ArticleDOI
Use of DNA barcodes to identify flowering plants
TL;DR: Comparison of the total plastid genomes of tobacco and deadly nightshade enhanced with trials on widely divergent angiosperm taxa suggest that the sequences in this pair of loci have the potential to discriminate among the largest number of plant species for barcoding purposes.
Journal ArticleDOI
New dates and new rates for divergence across the Isthmus of Panama
Nancy Knowlton,Lee A. Weigt +1 more
TL;DR: Patterns of divergence exhibited by allozymes and the mitochondrial COI gene are highly concordant for 15 pairs of snapping shrimp in the genus Alpheus, indicating that they provide a reasonable basis for estimating time since cessation of gene flow.
Journal ArticleDOI
Divergence in proteins, mitochondrial DNA, and reproductive compatibility across the isthmus of Panama.
TL;DR: Measurements of biochemical and reproductive divergence for seven closely related, transisthmian pairs of snapping shrimps indicate, however, that isolation was staggered rather than simultaneous, and the four least divergent pairs provide the best estimate for rates of molecular divergence and speciation.
Journal ArticleDOI
Comprehensive DNA barcode coverage of North American birds.
Kevin C. R. Kerr,Mark Y. Stoeckle,Carla J. Dove,Lee A. Weigt,Charles M. Francis,Paul D. N. Hebert +5 more
TL;DR: The consistent finding of constrained intraspecific mitochondrial variation in this large assemblage of species supports the emerging view that selective sweeps limit mitochondrial diversity.
Journal ArticleDOI
Sibling Species in Montastraea annularis, Coral Bleaching, and the Coral Climate Record
TL;DR: The Caribbean coral Montastraea annularis is shown to consist of at least three sibling species in shallow waters, and the two most commonly studied show highly significant differences in growth rate and oxygen isotopic ratios.
