  • DNA barcoding of echinopluteus larvae uncovers cryptic diversity in neotropical echinoids 
    Collin, Rachel; Venera-Ponton, Dagoberto E.; Driskell, Amy C.; Macdonald, Kenneth S.; Geyer, Laura B.; Lessios, Harilaos A.; Boyle, Michael J. (2020)
    Surveys of larval diversity consistently increase biodiversity estimates when applied to poorly documented groups of marine invertebrates such as phoronids and hemichordates. However, it remains to be seen how helpful this ...
  • Documenting neotropical diversity of phoronids with DNA barcoding of planktonic larvae 
    Collin, Rachel; Venera-Pontón, Dagoberto E.; Driskell, Amy C.; Macdonald, Kenneth S.; Chan, Kit-Yu Karen; Boyle, Michael J. (2019)
    Phoronid larvae, actinotrochs, are beautiful and complicated organisms which have attracted as much, if not more, attention than their adult forms. We collected actinotrochs from the waters of the Pacific and Caribbean ...
  • How I wonder what you are: Can DNA barcoding identify the larval asteroids of Panama? 
    Collin, Rachel; Venera-Ponton, Dagoberto E.; Driskell, Amy C.; Macdonald, Kenneth S.; Boyle, Michael J. (2020)
    As part of a project to document the diversity of larval invertebrates on both coasts of Panama, we collected and photographed 141 larval asteroids and sequenced fragments of their mitochondrial cytochrome c oxidase subunit ...
  • Unexpected molecular and morphological diversity of hemichordate larvae from the Neotropics 
    Collin, Rachel; Venera-Pontón, Dagoberto E.; Driskell, Amy C.; Macdonald, Kenneth S.; Boyle, Michael J. (2019)
    The diversity of tropical marine invertebrates is poorly documented, especially those groups for which collecting adults is difficult. We collected the planktonic tornaria larvae of hemichordates (acorn worms) to assess ...
