Projects

Several bryological research projects are currently taking place at Duke University, with support from the U.S. National Science Foundation.

Collaborative Research: AToL: Assembling the Pleurocarp Tree of Life: Resolving the rapid radiation using genomics and transcriptomics

A collaborative project between the University of Connecticut, Chicago Botanical Gardens and Duke University. This study focuses on untangling the relationships among species of pleurocarpous mosses that arose from an explosive diversification, on identifying the geologic or climatic shifts that triggered these events, and on understanding the significance of morphological innovations allowing adaptations to diverse habitats.

Dimensions: Collaborative Research: Genome structure and adaptive evolution in peatmosses (Sphagnum): ecosystem engineers

We’re starting on a new collaborative project this Fall. See the NSF press release here.


Past projects

A model systematic treatment of a hyper-diverse lineage descended from early land plants (aka, Frullania project)

A collaborative project between the Field Museum Chicago & Duke University, preparing monograph of two lineages within liverwort genus Frullania. [–> Frullania portal]

Phylogeny and speciation in Sphagnum section Subsecunda

The project has three major components. The first part involves a global analysis of peatmoss diversity in order to determine if genetic relationships reflect geographic proximity, or structural similarity among plants; that is, have similar morphologies in widely disjunct regions evolved convergently?. The second part of the research investigates ecological, genetic, and morphological variation in a group of closely related species surrounding S. subsecundum s.s. that are widespread in North America, Europe, and Asia.

NSF-PEET (Partnerships for Enhancing Expertise in Taxonomy): Systematics of the Daltoniaceae
(Collaborative with W. R. Buck, New York Botanical Garden)

NSF-ATOL (Assembling the Tree of Life): Phylogeny of liverworts

The project is a comprehensive collaborative investigation of liverwort phylogeny. The research team includes B. Goffinet (University of Connecticut: chloroplast genomics), Y. Qiu (University of Michigan: mitochondrial genomics), K. Renzaglia (Southern Illinois University: ultrastructural morphology), B. Crandall Stotler & R. Stotler (Southern Illinois University: anatomy, morphology, taxonomy), J. Engel & M. von Konrat (Field Museum in Chicago, specimen vouchering, taxonomy, educational outreach), N. Celinese & R. Beaman (Yale University: informatics), J. Shaw (Duke University: nucleotide sequencing).
