Modeling hurricane effects on mangrove ecosystems

Mangrove ecosystems are at their most northern limit along the coastline of Florida and in isolated areas of the gulf coast in Louisiana and Texas. Mangroves are marine-based forests that have adapted to colonize and persist in salty intertidal waters. Three species of mangrove trees are common to the United States, black mangrove (Avicennia...

Investigation into avian mortality in the Playa Lakes region of southeastern New Mexico: Final Report - June 1997

This Final Report is a review of work on a cooperative study undertaken by the USGS Biological Resources Division's National Wildlife Health Center (NWHC) and National Wetlands Research Center (NWRC; formerly the Southern Science Center) from 1994 through 1997. The study was initiated at the request of the Bureau of Land Management (BLM), through...

Use of a spatial decision support system for analysis of habitat use by wintering northern pintails

A multi-functional spatial decision support system (SDSS) was,developed at the spatial analysis branch Of the National Wetlands Research Center, and the wildlife analysis module of the system was used to study habitat use by wintering pintail. We instrumented female pintails at Catahoula Lake, Louisiana, in October of 1992-94 and located the...

The frequency and intensity of Atlantic hurricanes and their influence on the structure of south Florida mangrove communities

Hurricanes are formidable forces that wreak havoc on society and nature alike. Mangrove ecosystems are especially vulnerable because they thrive in the intertidal zone of tropical regions where hurricanes originate and are most frequent. Because mangroves are found at the land-sea interface where hurricanes are often most intense, these coastal...

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,...

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....

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...

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...

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...
