Annual oak leaf canopy litter percent carbon and nitrogen:Effect of Burning Patterns on Vegetation in the Fish Lake Burn Compartments
This study examines the effects of long-term prescribed burning treatments on vegetation structure and composition, productivity, and nutrient cycling in upland oak savanna and woodland vegetation. The basis for the study is an ongoing, experimental prescribed burning program begun in 1964 at Cedar Creek, and a similar program operating since 1962 on the adjacent Helen Allison Savanna property (owned by The Nature Conservancy). These prescribed burning programs are designed to subject upland oak communities (and some old fields) to different burn frequencies and patterns of burning, with the ultimate objectives of 1) restoring and maintaining the historically important savanna and open woodland vegetation, and 2) providing information about the effects of different burning patterns on vegetation structure and composition. This study addresses the latter of these two purposes and expands on it by also investigating possible influences of fire on resource availability (nutrients, water, and light) and net primary productivity. This study represents a continuation and expansion of experiments 015 and 094.
Percent carbon and nitrogen in leaf tissue:Specialization, maintenance of diversity and ecosystem consequences of growth defense trade-offs in a model system, the hyper-diverse willow communities of Cedar Creek
Cedar Creek includes a diversity of habitats, which support an astonishing number of species (15) from a single evolutionary lineage: the willow family (Salicaceae). The physiological tolerances and abiotic mechanisms that maintain natural diversity in this hyper-diverse system are beginning to be understood; the role of biotic interactions, however, remains a major gap in understanding. We hypothesize that insect herbivory plays a critical role in niche partitioning, providing an important explanation for high willow diversity. Using a replicated series of common gardens and insect herbivore manipulations in resource rich and resource poor habitats, we are testing for evolved trade-offs between defense investment and growth rate. We expect specialized plant syndromes to emerge along the continuum from ???herbivore escape??? via fast growth in high resource environments to ???anti-herbivore protection??? via heavy investment in defense in low resource environments. Evolved growth/defense strategies that promote diversity are also likely to have ecosystem consequences due to foliar chemical influences on decomposition and the composition and diversity of the insect communities they support. The proposed research takes advantage of natural diversity, providing an important model system at Cedar Creek.
