The upland hardwood component of Prince Edward Island's Acadian forest is among the best remaining examples of the precolonial landscape, but it has been severely fragmented during the past 300 years of human use and settlement. Despite the ecological importance of this remnant habitat and its level...

Using scanning electron microscopy and thin sectioning, the functional morphology of the gynoecium, anthers, and pollen grains of Ruppia maritima, widgeon grass, were studied. The funnel-like arrangement of the carpels directing pollen to the stigmatic regions, the buoyancy offered by the presence o...

The organogenesis of floral development in the dioecious clonal tree species Rhus hirta offers an excellent model system to study gender expression in dioecious plants. Pistillate and staminate flowers from developing inflorescences were collected from Grover Island, located off the northern shore o...
