Abstract:
This project examines the ecology and physiology of the diverse assemblage of ferns growing at Harvard Forest. Specifically, we seek to understand constraints on the photosynthetic potential of these plants in relation to their growth form and life cycle. We will examine patterns of root, stem (rhizome) and leaf growth, characteristics of the vascular system, and patterns of leaf gas exchange across eight species of ferns. Overall, the goal will be to understand the opportunities and constraints associated with a dependence upon adventitious roots, a leaf hydraulic system composed entirely of tracheids, and an absence of branching. Ferns, despite their abundance and well documented effects on forest regeneration, have received surprisingly little attention. These studies will thus be among the first to characterize the physiological ecology of these charismatic plants and will contribute to our understanding of the biology of this fascinating lineage.
Update 2008: Eddie's plans for work at Harvard Forest are limited this year, and he won't be working with an REU.:
