Bryophytes are a group of three disparate lineages (mosses, liverworts, and hornworts)
that are thought to be phylogenetically basal among extant land plants. The group
contains much species diversity and is particularly suited for studies of macroevolutionary,
population genetic, and ecological processes. However, a major limitation in the
use of bryophytes as study systems for evolutionary and ecological processes has
been the lack of basic taxonomic knowledge of many groups from many regions, particularly
the tropics. To achieve this knowledge it is necessary to train a new generation
of taxonomists skilled in all the necessary techniques, theories, and background
information. The need for cooperative, modern studies that cross national and
disciplinary boundaries is paramount.
This research involves a particular bryophyte study group, the moss family
Calymperaceae, chosen to allow us to achieve three goals: (1) Train students
in the full breadth of systematic techniques; (2) Provide useful monographs
of important groups; (3) Address issues of theoretical and conceptual interest
in biogeography and evolutionary diversification.
The research focuses on three levels: (1) The circumscription and higher-level
relationships of the family Calymperaceae; (2) Relationships of the genera (and
major sections) within the family (the major goal being to verify the monophyly
of Mitthyridium and select a few other monophyletic subgroups of the family
for monographic study); (3) Species delimitations and relationships within the
selected subgroups (e.g., Mitthyridium) culminating in world monographs. At
all these levels, but particularly in the latter, we are also considering biological,
ecological and geographic facters influencing diversification.
This research involves field and herbarium studies to discover and refine taxonomic
characters useful at all three levels. Laboratory studies including SEM, morphometrics,
culture studies, and DNA sequencing are being used to supplement the morphological
data. The project includes training in these areas at the undergraduate, graduate,
and postdoctoral levels.
