Title: The impact of vertebrate herbivores on wetland vegetation in Atchafalaya Bay, Louisiana
Journal: Estuaries and Coasts
Authors: D. E. Evers, C. E. Sasser, J. G. Gosselink, D. A. Fuller, and J. M. Visser
Date: 1998
Summary: The effects of herbivory by waterfowl and nutria were measured because of vegetation loss in Sagittaria spp. dominated marshes along the coast of Louisiana. One set of study plots was set up on islands in Atchafalya Delta (fall 1985), while the other set was established on islands in Wax Lake Delta (winter 1986). Each set of plots included an exclosure that barred just nutria, one that barred just waterfowl, one that barred both, and an open grazing plot. Aboveground biomass and species composition were measured at the end of the growing season in 1986 and 1987. Belowground biomass was collect ...

Title: The interactive effects of fire and herbivory on a coastal marsh in Louisiana
Journal: Wetlands
Authors: M. A. Ford, and J. B. Grace
Date: 1998
Summary: The interaction of nutria herbivory with fire was investigated on three types of marshes along the Pearl River basin in Gulf Coast of Louisiana. In each marsh, two, 10 m² plots were established in Spartina patens, Sagittaria lancifolia, and Panicum virgatum dominated marshes. One plot was burned in the fall before sampling, while the other remained unburned. Inside each plot, two m2<\sup> subplots were established with one plot fenced to exclude nutria grazing while the other plot was unfenced. Plots were set up in the fall and sampled at that time and the next t ...

Title: Herbivore effects on plant species density at varying productivity levels
Journal: Ecology
Authors: L. Gough, and J. B. Grace
Date: 1998
Summary: In this study, Gough and Grace studied plant community responses to fertilization and herbivory in Louisiana brackish and freshwater marshes. Species density was greater in plots that were grazed because grazing pressure limited the ability of dominant plants to outcompete other plants and reduce plant community diversity. Biomass was greatest in plots that were fertilized, suggesting that plant growth is limited by the nutrient availability in these marshes. These results indicate that grazing can enhance productivity and species diversity of brackish and freshwater marshes in Louisiana wh ...

Title: The effects of vertebrate herbivory on plant community structure in the coastal marshes of the Pearl River, Louisiana, USA
Journal: Wetlands
Authors: K. L. Taylor, and J. B. Grace
Date: 1995
Summary: The impacts of nutria (Myocastor coypus) herbivory using two treatments (grazed and ungrazed) were studied along the Mississippi and Louisiana border using plots in three different marsh communities (fresh, oligohaline and mesohaline) along an elevational and salinity gradient. Each plot was maintained and monitored over two growing seasons. All of the aboveground biomass in each of the plots was clipped and total biomass of all species and species richness were recorded at the completion of the second year of the study. ...

Title: Effects of simulated feeding by snow geese on Scirpus americanus rhizomes
Journal: Oecologia
Authors: J. F. Giroux, and J. Bedard
Date: 1987
Summary: Over two years a series of experiments were conducted at Cap St. Ignace, Quebec (47° 02' N, 70° 29' W) to examine the effects of underground biomass herbivory on mortality, net above ground biomass and below ground biomass of Scirpus americanus. Rhizomes were dug, washed, sorted, assigned to treatments, and planted in metal basins located in the salt marsh that were free of non-test rhizomes. Number of shoots, buds, inflorescences, rhizome length and production were recorded. Intensity of rhizome removal was simulated by clipping rhizomes to var ...
