Impact Of Giant Miscanthus (Miscanthus X Giganteus) Cultivation On Midwestern Farmland Birds, Matthew Craffey
Impact Of Giant Miscanthus (Miscanthus X Giganteus) Cultivation On Midwestern Farmland Birds, Matthew Craffey
Masters Theses
Giant Miscanthus (Miscanthus x giganteus) is a promising bioenergy feedstock, newly introduced to North America. However, the qualities that make Giant Miscanthus an attractive bioenergy feedstock may pose challenges to local wildlife. To assess the impacts of Giant Miscanthus on Midwestern farmland birds, I conducted point count and vegetation surveys at three sites in east-central Illinois where Giant Miscanthus was being cultivated. I used occupancy modeling to assess the relative influence of Giant Miscanthus on five species relative to other habitat and landscape characteristics. Dickcissel (Spiza Americana), Eastern Meadowlark (Sturnella magna), and Red-Winged Blackbird …

Distiphallus Morphology And Its Role In Copulation Dynamics In Anastrepha Suspensa (Loew), Taylor J. Inboden
Masters Theses
Anastrepha suspensa (Diptera; Tephritidae) is an agricultural pest species
causing severe economic damage and is controlled, in part, by applying knowledge
of this species' reproduction (e.g., disrupting fertile copulations by SIT). During
copulation, males transfer sperm as well as protein rich fluids through an aedeagus
and distiphallus, which females then store in three spermathecae and one ventral
receptacle. Within the female reproductive tract, the ventral receptacle and the
three spermathecae are strategically separated from each other. I hypothesized
males' ability to direct sperm transfer within the female reproductive tract is
through the structures found in the distiphallus. Utilizing scanning electron …
