Species in the genus are distinguished by the arrangement of pinnules in rows along one or both sides of a main axis, by the random placement of pinnules around the main axes, degrees of branching, and thallus size, but it is well established that these discrete morphological features do not simultaneously define genetic clusters recognized on the basis of DNA sequence comparisons. This range in morphological variation renders species identification challenging, and potentially complicates the correct attribution of species-specific chemical signatures amongst <i>Bryopsis<\/i> species. For this study, the student\u2019s task will be to sequence two standard DNA Barcode regions, <i>tuf<\/i>A and <i>rbc<\/i>L, from live and\/or preserved specimens of <i>Bryopsis<\/i> to identify closely-related specimens from throughout its western, north Atlantic distribution from Rhode Island to Panama, including specimens from the eastern tropical Pacific. The student will then assess morphology within genetically-defined clusters, and establish the geographic ranges of those clusters. We will then be positioned to establish how many species of <i>Bryopsis<\/i> exist in the western Atlantic, and determine if southern genotypes are becoming newly established in more northerly latitudes as a response to global climate change or through biological invasion.<\/span><\/p>\n<p style=\"margin: 13.0pt 0in 13.0pt 0in\"><i><span style=\"color: black\">This project involves field, lab and computational work.<\/span><\/i><\/p>\n<p style=\"margin: 13.0pt 0in 13.0pt 0in\"><b><span style=\"color: black\">&nbsp;<\/span><\/b><\/p>\n<p style=\"margin: 13.0pt 0in 13.0pt 0in\"><b><span style=\"color: black\">Required\/Preferred Skills<\/span><\/b><\/p>\n<p style=\"margin: 13.0pt 0in 13.0pt 0in\"><span style=\"color: black\">No prior experience with fieldwork, sample collection, laboratory analysis, or data analysis are required.
