Duke Bryology Laboratory projects
Sphagnum squarrosum  



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

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.

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

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.

Past projects


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). There is support for visitors to the lab who wish to work on liverwort groups of particular interest to them. Contact Jon Shaw if interested.
