KRUG LAB - EVOLUTIONARY AND LARVAL ECOLOGY OF MARINE INVERTEBRATES
John Berriman, M.S. 2014
John pioneering the integration of molecular and morphological methods for species delimitation in my lab, to process by which samples of unidentified specimens commonly lumped under one name can be split into candidate species representing genetically distinctive lineages with diagnostic morphological characters.
Five of the new Oxynoe species discovered during John's M.S. thesis.
John used three methods of molecular species delimitation to analyze mitochondrial or multilocus nuclear genetic data. He split specimens representing five nominal species of Lobiger and Oxynoe into 16 candidate species, doubling the biodiversity in family Oxynoidae. He then analyzed the morphology of 10 species of Oxynoe, leading to the description of seven new species.
