Effect of hydrologic management on marsh surface sediment deposition in coastal Louisiana Effect of hydrologic management on marsh surface sediment deposition in coastal Louisiana

High rates of coastal land loss in Louisiana have prompted efforts to maintain or restore coastal wetland habitats, and structural management of marsh hydrology is one of a number of approaches that has been adopted. The aim of this study was to determine the effect of hydrologic management measures on marsh-surface sediment deposition in the Mississippi deltaic plain. Four impoundments...

Community involvement in a multimedia outreach project for Caddo Lake, Texas Community involvement in a multimedia outreach project for Caddo Lake, Texas

Caddo Lake is located in northeast Texas and northwest Louisiana and is the largest freshwater lake in Texas. A portion of the lake in Texas has been designated a "Wetland of International Significance" under the Ramsar Convention of the United Nations. The human community in the watershed has experienced a number of hydrological alterations to Caddo Lake over the last 100 years by the...

Salt tolerance of southern baldcypress Salt tolerance of southern baldcypress

Historically, cypress-tupelo swamps covered much of the low-lying coastal regions of the Southeast. However, saltwater intrusion and increased flooding over the past 30 years, combined with past logging, have depleted the numbers and decreased the survival and growth of baldcypress (Taxodium distichum) in coastal areas along the Gulf of Mexico.

Evaluation of a mallard HSI model for the Lower Mississippi Valley Evaluation of a mallard HSI model for the Lower Mississippi Valley

We evaluated a habitat suitability (HSI) model developed for mallards (Anas platyrhynchos) wintering in the Lower Mississippi Valley by comparing mallard densities obtained from aerial surveys with habitat suitability indices derived from satellite imagery for 25, 256km2 sampling units. Regression models that related mallard densities to habitat suitability indices accounted for only 29%...

The effects of herbivory on neighbor interactions along a coastal marsh gradient The effects of herbivory on neighbor interactions along a coastal marsh gradient

Many current theories of community function are based on the assumption that disturbances such as herbivory act to reduce the importance of neighbor interactions among plants. In this study, we examined the effects of herbivory (primarily by nutria, Myocastor coypus) on neighbor interactions between three dominant grasses in three coastal marsh communities, fresh, oligohaline, and...
