Comparison of Landsat Thematic Mapper and high resolution photography to Identify change in complex coastal wetlands Comparison of Landsat Thematic Mapper and high resolution photography to Identify change in complex coastal wetlands
Landsat Thematic Mapper (TM) images were used to generate pre- and post- hurricane classifications of a complex wetland environment in southern Louisiana. Accuracies were estimated as 77% and 81.5% for the pre- and post- classifications that included water, emergent vegetation, floating vegetation, and mud flats. From the two classifications, areas of emergent vegetation loss were...

Capture myopathy in a captive Black-bellied Whistling Duck Capture myopathy in a captive Black-bellied Whistling Duck
A female captive-raised Black-bellied Whistling Duck exhibited signs of capture myopathy within 24 hours after a strenuous capture. Serum creatine kinase activity 48 hrs after capture was 23,680 IU/L and aspartate aminotransferase activity was 898 IU/L. Postmortem lesions included large, pale areas of muscle tissue in the hind limbs and heart. Histologic lesions of skeletal muscle...

A comparison of wetland tree growth response to hydrologic regime in Louisiana and South Carolina A comparison of wetland tree growth response to hydrologic regime in Louisiana and South Carolina
Numerous investigations have examined the growth of wetland tree species under a variety of hydrologic conditions. Most studies have compared flooded versus non-flooded conditions in greenhouses or in one to a few field sites near each other or within the same region. Comparisons of wetland tree growth among widely separated areas of the country are rare. This study compared the diameter...

A SAS® code to correct for non-normality and non-constant variance in regression and anova models using the box-cox method of power transormation A SAS® code to correct for non-normality and non-constant variance in regression and anova models using the box-cox method of power transormation
A computer program written in SAS ® code for the Box–Cox family of power transformations is presented. The purpose of the program is to suggest a power transformation for the positive continuous response variables in only regression and ANOVA models. A brief overview of data transformation in regression and analysis of variance is given.An example using real data from the U.S...

Woody debris decomposition in the Atchafalaya River Basin of Louisiana following hurricane disturbance Woody debris decomposition in the Atchafalaya River Basin of Louisiana following hurricane disturbance
The contribution of woody debris to some biogeochemical functions of forested wetlands was examined in the Atchafalaya River Basin in Louisiana following disturbance by Hurricane Andrew. Woody debris decomposition processes were characterized in terms of mass, C, N, and P dynamics. These were compared between different diameters of debris, areas recieving different intensities of...

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...
