Vernal pools are sensitive environments that provide critical habitat for many species, including amphibians. These small water bodies are not always protected by pesticide label requirements for no-spray buffer zones, and the occurrence of pesticides in them is poorly documented. In this study, we investigated the occurrence of glyphosate, its primary degradation product aminomethylphosphonic acid, and additional pesticides in vernal pools and adjacent flowing waters. Most sampling sites were chosen to be in areas where glyphosate was being used either in production agriculture or for nonindigenous plant control. The four site locations were in otherwise protected areas (e.g., in a National Park). When possible, water samples were collected both before and after glyphosate application in 2005 and 2006. Twenty-eight pesticides or pesticide degradation products were detected in the study, and as many as 11 were identified in individual samples. Atrazine was detected most frequently and concentrations exceeded the freshwater aquatic life standard of 1.8 micrograms per liter (microg/l) in samples from Rands Ditch and Browns Ditch in DeSoto National Wildlife Refuge. Glyphosate was measured at the highest concentration (328 microg/l) in a sample from Riley Spring Pond in Rock Creek National Park. This concentration exceeded the freshwater aquatic life standard for glyphosate of 65 microg/l. Aminomethylphosphonic acid, triclopyr, and nicosulfuron also were detected at concentrations greater than 3.0 microg/l.

We provided fenbendazole to captive (N q 77) and free-ranging (3 study areas) white-tailed deer (Odocoileus virginianus) in Louisiana to determine effects on gastrointestinal nematode burdens. Fenbendazole reduced gastrointestinal nematode burdens of captive and free-ranging white-tailed deer. Mean eggs per gram of feces from captive deer decreased P

An extensive review of the literature on 13 species of neotropical migratory birds (NTMB) that breed on the U.S. Department of Agriculture, Forest Service, Kisatchie National Forest (KNF), in Louisiana, was the basis for this publication. These species were selected because they are known to breed on the KNF and represent a cross section of the various taxa of NTMB that exist in the forest. Included for each of the species are sections on distribution, biology, habitats, and density. Also discussed are population trends for the selected species and forest management practices that may influence distribution and abundance of NTMB. In addition, some areas of research that are suggested by this review and that would help fill gaps in the present state of knowledge for the selected birds are identified. ACKNOWLEDGMENTSThe authors thank David Pashley of the Louisiana Nature Conservancy for providing information on the breeding neotropical migratory birds of the U.S. Department of Agriculture, Forest Service, Kisatchie National Forest, from which the species were selected for abstracting. Special thanks are extended to Gary Lester and Bill Vermillion of the Louisiana Department of Wildlife and Fisheries' Natural Heritage Program for contributing survey data on breeding birds, from which Statewide distributions of the abstracted species were determined. Thanks also to artist Lisa L. Barbe for the fine color illustrations. Finally, appreciation goes to USDA Forest Service personnel Jim Dickson, Richard Conner, Marq Webb, Alan Williamson, and Jack Hill and to USDI Fish and Wildlife Service biologist William "Chuck" Hunter for reviewing the manuscript and making valuable comments and suggestions.
