Factors Influencing Stem Density of Creekbank Spartina alterniflora in a New England Salt Marsh
Stem density patterns for smooth cordgrass, Spartina alterniflora, are highly variable both among years and within the growing season. These variations can have consequences for the overall primary productivity of the salt marsh system, as well as its ability to provide essential ecosystem functions. In this study, I explored factors that could be driving observed variations in four tidal creek...
متن کاملRibbed Mussels and Spartina Alterniflora Production in a New England Salt Marsh
The ribbed mussel, Geukensia demissa, is commonly found associated with the salt marsh cordgrass, Spartina alterniflora. Mussels attach to the basal portion of S. alterniflora stems with strong proteinaceous byssal threads and deposit fecal material on the surrounding sediment as a byproduct of their filter-feeding activity. Here I demonstrate by manipulating mussel densities in the field that ...
متن کاملA specialist detritivore links Spartina alterniflora to salt marsh food webs
Because most plant production is subject to senescence and is eventually consumed by detritivores, the factors that drive detritivore diet choice are pivotal to the flow of energy and materials through food webs. Here, we investigated the common salt marsh amphipod Gammarus palustris, which is a habitat specialist that feeds specifically on the dead leaves of its living host plant, salt marsh c...
متن کاملEffects of Spartina alterniflora invasion on the communities of methanogens and sulfate-reducing bacteria in estuarine marsh sediments
The effect of plant invasion on the microorganisms of soil sediments is very important for estuary ecology. The community structures of methanogens and sulfate-reducing bacteria (SRB) as a function of Spartina alterniflora invasion in Phragmites australis-vegetated sediments of the Dongtan wetland in the Yangtze River estuary, China, were investigated using 454 pyrosequencing and quantitative r...
متن کاملMapping Spartina alterniflora Biomass Using LiDAR and Hyperspectral Data
Large-scale coastal reclamation has caused significant changes in Spartina alterniflora (S. alterniflora) distribution in coastal regions of China. However, few studies have focused on estimation of the wetland vegetation biomass, especially of S. alterniflora, in coastal regions using LiDAR and hyperspectral data. In this study, the applicability of LiDAR and hypersectral data for estimating S...
