Huenneke, L. and R. Sharitz (1990). "Substrate heterogeneity and regeneration of a
swamp tree, Nyssa aquatica." American Journal of Botany 77: 413-419.
These studies, conducted in the Savannah River floodplain on the SRS, demonstrate the
importance of substrate heterogeneity in providing safe sites for seed germination and seedling
establishment and growth. In cypress-tupelo forests, such microsites are especially important to
recruitment when water levels are managed in such a way that the forest floor remains inundated
for prolonged times during the growing season, as was the case in the sites of the Huenneke study.
Microsite heterogeneity (pit and mound topography caused by windthrown trees) also provides an
array of soil moisture and temperature conditions that may enhance establishment of bottomland
hardwood species such as oaks.
Importance of winter flood events in seed dispersal
Liu, E., E. Iglich, R. Sharitz and M. Smith (1990). "Population genetic structure of
baldcypress (Taxodium distichum) in a thermally affected swamp forest." Silvae
Genetica 39: 129-133.
Schneider, R. and R. Sharitz (1988). "Hydrochory and regeneration in a bald cypresswater
tupelo swamp forest." Ecology 69(4): 1055-1063.
These two studies, conducted on the Savannah River floodplain on the SRS, demonstrate the
importance of floods as a vector of dispersal in cypress-tupelo forests. The Schneider and Sharitz
paper measures hydrochory (water dispersal) directly by the release and recapture of marked
seeds. The Liu et al. paper demonstrates the importance of dispersal in maintaining genetic
variability within cypress populations but suggests that a few trees shedding seeds during periods
of low water and suitable conditions for seedling establishment may be responsible for spatial
heterogeneity in allele frequencies.
Invasive species (Chinese tallow)
Jones, R. and R. Sharitz (1990). "Effects of root competition and flooding on growth of
Chinese tallow tree seedlings." Canadian Journal of Forest Research 20: 5730578.
Chinese tallow is an invasive tree species in the Savannah River floodplain.
Highly flood and shade tolerant, the Chinese tallow has been successful in low
wet areas of the floodplain.

competitive ability of two wetland tree species and an exotic." Castanea 66(3):

Invertebrates
Thorp, J., E. McEwan, M. Flynn and F. Hauer (1985). "Invertebrate colonization of
submerged wood in a cypress-tupelo swamp and blackwater stream." American
Midland Naturalist 113(1): 56-68.
This article investigates the wetland characteristics that influence the colonization of wood snags
by invertebrates. Uniform sections of tupelo logs were submerged in a swamp tributary, swamp,
and swamp outflow locations. The logs were rapidly colonized and most reached a steady-state in
