| Summary: | 5 and 9 years) were compared with a newly created marsh in abundance and sediment parameters, two created marshes (ages also examined. overall infaunal densities and species alterniflora. The vertical distribution of the infauna was and low infaunal abundance. However, organic matter and as food by estuarine animals. Newly created marshes often collected in cores at culms of Spartina alterniflora, and correlated with high infaunal abundances, more animals were detritus biomass, and sediment organic content and grain have relatively low levels of organic matter in the sediments have stimulated efforts to create marshes on dredged High rates of wetland loss in the northern Gulf of Mexico infaunal populations in created marshes may develop over levels were lowest in the newest marsh. There was no general marsh was dominated by the subsurface deposit feeding material. These marshes may not function similarly to their matter and detritus and infaunal abundance. However, there matter over the two-year study period, and organic matter most of the infauna were found in the upper 2.5 cm of natural counterparts in supporting infaunal populations used organic matter concentrations control infaunal populations. polychaete, Capitella capitata, while the two older marshes relationship appeared strongest during spring and summer. relationship between concentrations of sediment organic richness in the youngest marsh were comparable to those in Samples were collected at and between culms of Spartina sediment. There was evidence of accumulation of organic size, at different elevations in each of the marshes. Streblospio benedicti. In general, low elevation was taken quarterly to measure infaunal density, live root and the amount of live roots and rhizomes present, and this the other marshes within the first year. However, the newest The results of this study suggest that factors other than the same location. over a two-year period, core samples were time. To examine the relationships between infaunal was a positive relationship between infaunal abundance and were dominated by the surface deposit feeding polychaete, |
