Woody litter decomposition following clear-cutting. Ecology 63: 35-42. | Unconfined Quercus prinus woody litter of three size classes (0-1, 1-3, and 3-5 cm diameter) was placed on forest floors of a control hardwood watershed and on mesic and xeric sites of a clear-cut watershed at Coweeta. The effect of site differences on decomposition rate was greater than the effect of diameter, although an inverse relationship between diameter and decay coefficient is suggested.

Seastedt, and D.A. Crossley Jr. 1980. The abundance, distribution and effects of clear-cutting on Cryptostigmata in the southern Appalachians. Environmental Entomology 9: 618-623. | Oribatid mites were sampled from deep soil, soil cores, litter bags, and woody litter on a clearcut and adjacent control hardwood watershed at Coweeta. The inclusion of woody litter and deep soil samples caused the total number of genera found to reach 72, as opposed to the 37-42 genera range reported in other studies.

The Role of Leaf Litter and Small Wood in the Retention of Fine Particles During Storms in an Appalachian Headwater Stream. [thesis]. Blacksburg (VA): Virginia Polytechnic Institute and State University. | Streams are constantly subject to downstream movement of materials. The role of fallen leaves in resisting downstream transport of particulates is largely unquantified. The litter exclusion study at Coweeta presented the opportunity to study a stream without litter input. I expected removal of leaf litter to reduce the capacity of the stream to retain fine particulate organic matter, FPOM. However, leaves are also a major source of FPOM. I studied the effect of leaf exclusion on FPOM transport by field sampling and by generating computer simulations of particle transport in the stream.

Soil Science 45(1): 37-45. | Land managers are concerned with maintaining crop, forest, and range production. If erosion losses from moderately deep or shallow soils occur faster than the soil is replenished by weathering from underlying bedrock or consolidated sediments, productivity will decline. Therefore, rates of soil formationf can be considered constraints on tolerable soil losses from relatively shallow soils; their longterm soil-loss tolerances can be equated with their rates of formation from bedrock or consolidated sediments. There are few data for determining rates of soil formation, however. Data from small, nonagricultural watershed studies in which the inputs and outputs of silica and the major cations have been measured can be utilized for this purpose.

Journal of Ecology 96:303-313. | To examine potential impacts of non-random species loss on ecosystems, we studied additive and non-additive effects of litter mixing on decomposition. A full-factorial litterbag experiment was conducted using four deciduous leaf species, from which mass loss and nitrogen content were measured. Data were analysed using a statistical approach that first looks for additive identity effects based on the presence or absence of species and then significant species interactions occurring beyond those. It partitions non-additive effects into those caused by richness and/or composition.

Seedling Recruitment in Southern Appalachian Forests: Does Spatial Heterogeneity Maintain Species Diversity? [dissertation] Durham (NC): Duke University. | Spatial heterogeneity in biotic and abiotic factors is one mechanism proposed to maintain species diversity. In forests, canopy gaps are a major source of environmental heterogeneity, providing for increased light levels that may play a central role in tree regeneration and subsequent patterns of species diversity. While many studies have examined the direct effects of canopy gaps on seedling recruitment, few have considered the interaction of other sources of spatial heterogeneity with canopy gap formation. I examine the potential for spatial heterogeneity in understory cover, mineral resources, moisture, seed and seedling predation, and overstory condition to contribute to species coexistence.

Meyer (eds.), Stream organic matter budgets. Journal of the North American Benthological Society. 16: 104-108. | This chapter is part of a multi-site analysis of organic matter dynamics in streams. This chapter compares litterfall inputs to the streams. Climate (latitude) and vegetation type were more important than steam order in predicting litter inputs across a broad geographic range of streams, although within a river basin litterfall decreased with increasing stream order.

Ragsdale. 1984. Chronological sequence of element concentrations in wood of Carya spp. in the southern Appalachian Mountains. Canadian Journal of Forest Research. 15: 477-483. | Tree-ring analyses of hickory (Carya spp.) from the long-term ecological research site, Coweeta Hydrologic Research Laboratory, revealed that concentrations (micrograms per gram) of lead, aluminum, and zinc are increasing, that concentrations of copper, cadmium, nickel, and manganese have remained generally constant since the 1880's, and that hickory annual radial growth increments are declining. Lead, aluminum, and zinc burdens (microgram per growth interval), unlike their respective concentrations, have remained generally constant during the 1900's. The interpretation of growth and burden data indicates that hickory trees at Coweeta are in a mature phase of their life cycle and that annual growth does not seem to be reduced by pollutants.
