Marcia J. Waterway PhD.
Associate Professor and Curator of the McGill University Herbarium
Research interests
Dr Waterway's research interests are plant systematics, phylogeny and
ecological genetics, with emphasis on the Cyperaceae. The focus of her
research program is to understand the patterns of species diversity, genetic
diversity and clonal diversity in plants in relation to the environments in which
they grow, using the genus Carex as a model system. Patterns of species
diversity vary widely among the groups of flowering plants. Within the
monocotyledons, three large families account for most of the species: grasses
(Poaceae), sedges (Cyperaceae) and orchids, (Orchidaceae). Each of these
families has both small and large genera, with the genus Carex in the
Cyperaceae being one of the ten most species-rich genera in the world. What
accounts for this extreme diversity within a single group of plants? Can we
identify the different evolutionary (genealogical) lineages within this genus?
How is this diversity apportioned among the evolutionary lineages within Carex?
What structural characteristics and ecological preferences are associated with
these species-rich lineages? Can we discern biogeographic patterns related to
ancient geological events or recent migrations associated with glaciation? Has
there been co-evolution of this genus with its fungal pathogens? Are patterns
of clonal diversity within rhizomatous species correlated with environmental
heterogeneity? These are some of the questions that she and her students
seek to answer in their research. The genus Carex is the largest genus in
Canada and is widespread in temperate, boreal, subarctic and arctic habitats,
including both wooded and open sites. Rhizomatous sedges dominate in many
wetland habitats and woodland Carex species often account for as much as
10% of the herbaceous understory flora in temperate and boreal forests. In
collaboration with colleagues from around the world, they are developing a
phylogenetic hypothesis for the genus Carex using DNA sequence data and
using this phylogeny to study character evolution and the biogeographic
patterns within the genus. These studies of the correlations among lineage
diversification, ecological preferences, and structural innovations contribute to
understanding the evolutionary processes that generate diversity.
