    Abstract: <p>Sexual reproduction in flowering plants depends on investment in reproduction, the mode of pollen transfer, the availabilities of nutrient resources and potential mates, and the spatial scales over which these processes take place. In this thesis, I studied the general reproductive biology of Shepherdia canadensis (L.) Nutt. (Elaeagnaceae) and the suite of pollinators that visit the… more

    The Spatial Dynamics of Wind Pollination in Broadleaf Cattail (Typha latifolia): A New Method to Infer Spatial Patterns of Pollen Dispersal

    Name(s): Creator (cre): Ahee, Jordan, Thesis advisor (ths): Dorken, Marcel E, Degree committee member (dgc): Freeland, Joanna R, Degree committee member (dgc): Burness, Gary, Degree committee member (dgc): Pond, Bruce, Degree granting institution (dgg): Trent University
    Abstract: <p>Natural populations of flowering plants rarely have perfectly uniform distributions, so trends in pollen dispersal should affect the size of the pollination neighbourhood and influence mating opportunities. Here I used spatial analysis to determine the size of the pollination neighbourhood in a stand of the herbaceous, wind-pollinated plant (<italic>Typha latifolia</italic>;… more
