Dispersal by cattle of salt-marsh and dune species into salt-marsh and dune communities

Salt Marsh Tidal Channels

Salt marsh tidal channels are highly sinuous. For this project, field surveys and aerial photographs were used to characterize the planform of tidal channels at China Camp Marsh in the San Francisco Bay, California. To model the planform evolution, we assume that the topographic curvature of the channel centreline is a key element driving meander migration. Extraction of curvature data from a p...

Interactions among plant species and microorganisms in salt marsh sediments.

The interactions among Spartina patens and sediment microbial populations and the interactions among Phragmites australis and sediment microbial populations were studied at monotypic sites in Piermont Marsh, a salt marsh of the Hudson River north of New York, N.Y., at key times during the growing season. Arbuscular mycorrhizal fungi (AMF) effectively colonized S. patens but not P. australis, an...

Using Avian Communities to Evaluate Salt Marsh Restoration

The objectives of this study were to document avian species inhabiting West River Memorial Park in New Haven, Connecticut and develop goals for restoration of a salt marsh bird community. Restoration goals were based on the breeding season bird community at the restoration site, breeding season communities of less disturbed salt marshes, and a literature review. Community descriptions included ...

Consumer trait variation influences tritrophic interactions in salt marsh communities

The importance of intraspecific variation has emerged as a key question in community ecology, helping to bridge the gap between ecology and evolution. Although much of this work has focused on plant species, recent syntheses have highlighted the prevalence and potential importance of morphological, behavioral, and life history variation within animals for ecological and evolutionary processes. ...
