UNLABELLED PREMISE OF THE STUDY A microcosm unit with tidal simulation was developed to address the challenge of maintaining ecologically relevant tidal regimes while performing controlled greenhouse experiments on smooth cordgrass, Spartina alterniflora. • METHODS AND RESULTS We designed a simple, inexpensive, easily replicated microcosm unit with(More)
Growth and survival of transplanted vegetation for salt marsh restoration can be greatly affected by edaphic conditions. We investigated the potential for an organic carbon sediment amendment, alginate, to enhance establishment and growth of Spartina alterniflora transplants, as well as colonization by macroinvertebrates commonly associated with S.(More)
Salt marsh restoration is hypothesized to provide shoreline stabilization, increased fish habitat, and organic carbon subsidies for estuarine food webs. Organic carbon comes from diverse primary producers that differ in carbon fixation rates and areal extent within wetland systems. This study was designed to obtain some of the first estimates of the(More)
Pepper is the main vegetable crop grown in the Arava region of southern Israel. It is grown in the winter in nethouses and greenhouses. Low temperature wilt of mature pepper plants has been known for years in this region. The incidence of plant wilting was usually low when the soil was pretreated with methyl bromide. In recent years methyl bromide usage has(More)
In nitrogen-limited temperate marshes, increasing nitrogen availability via biological mechanisms such as N2 fixation and organic matter mineralization may lead to elevated marsh plant growth and macroinvertebrate densities. A polysaccharide, alginate, known to enhance microbial activity was added to sediment in a salt marsh (GA, USA) and the responses of(More)
