Book Inorganic Elements on the Alamosa Monte Vista National Wildlife Refuge and Relationships to Birds

Download or read book Inorganic Elements on the Alamosa Monte Vista National Wildlife Refuge and Relationships to Birds written by Andrew S. Archuleta and published by . This book was released on 1992 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive evaluation of elemental contamination was done on the Alamose/Monte Vista national Wildlife Refuge, San Luis Valley, Colorado,during 1989-90. Water, sediment, mallards, mallard eggs, American coots,and mallard food items were collected for elemental analyses. In addition, adult mallards were collected during winter and 20 different tissues were removed for histological analysis and diagnosis of avian cholera. Copper and zinc from several sources exceeded aquatic life standards for the Rio Grande River Basin. Acute toxicity tests using Ceriodaphnia dubia as the test organism were performed on water samples during both years. In 1989, mortality of the test organisms for all samples was less than 20%. In 1990, a sample from well #7 resulted in 44% mortality and a sample from well #5 resulted in 33% mortality.Chemical characteristics of all water samples were within normal ranges for wetlands during both years.

This book was released on 2014-03-04 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of an interagency agreement between the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS), the Alamosa/Monte Vista/Baca National Wildlife Refuge Complex requested help with the synthesis of scientific information for 10 focal species and their habitat requirements in response to common Refuge management activities in the San Luis Valley, Colorado. This information will be instrumental in developing the Service's Comprehensive Conservation Plan (CCP), which is required by law for each unit of the National Wildlife Refuge System. After consultation with Refuge managers and USGS staff, the 10 species chosen for detailed literature reviews and synthesis of information were the following: (1) American Avocet (Recurvirostra americana); (2) Wilson's Phalarope (Phalaropus tricolor); (3) Sora (Porzana carolina); (4) Whitefaced Ibis (Plegadis chihi); (5) Black Tern (Chlidonias niger); (6) Short-eared Owl (Asio flammeus); (7) Brewer's Sparrow (Spizella breweri); (8) Savannah Sparrow (Passerculus sandwichensis); (9) Northern Leopard Frog [Lithobates (=Rana) pipiens]; and, (10) Tadpole Shrimp (Triops longicaudatus).

Book Groundwater Recharge in a Desert Environment

Download or read book Groundwater Recharge in a Desert Environment written by James F. Hogan and published by American Geophysical Union. This book was released on 2004-01-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study. Discussions ondeveloping environmental tracers to fingerprint sources and amounts of groundwater at the basin scalethe critical role of vegetation in hydroecological processesnew geophysical methods in quantifying channel rechargeapplying Geographical Information System (GIS) models to land surface processescoupling process-based vadose zone to groundwater modeling, and more make this book a significant resource for hydmlogists, biogeoscientists, and geochemists concerned with water and water-related issues in arid and semiarid regions.

Book The Laguna Madre of Texas and Tamaulipas

Download or read book The Laguna Madre of Texas and Tamaulipas written by John Wesley Tunnell and published by Texas A&M University Press. This book was released on 2002 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Laguna Madre of Texas and Tamaulipas is the only hypersaline coastal lagoon on the North American continent and only one of five worldwide. Extending along 277 miles of shoreline in South Texas and northeastern Mexico, the lagoon is renowned for its vast seagrass meadows, huge wintering redhead population, and bountiful fishing grounds. Recent concerns about increasing human activity have focused attention on the long-term health of the Laguna Madre as growing population pressures, pollution problems, and dredging threaten this unique ecosystem. The Nature Conservancy, whose mission is the conservation of biodiversity through protection of habitat, recognized the need to compile all known information about the Laguna Madre in order to move ahead with a science-based conservation agenda. This book is the result. Taking an ecosystem approach to the study of this rich habitat, the authors first provide an overview of the natural history of the Laguna Madre and adjacent areas, including an essay on the importance of the region's private ranches. Succeeding chapters discuss the diverse natural resources of the lagoon—seagrasses, open bays, tidal flats, barrier islands, abundant waterfowl, colonial waterbird rookeries, sea turtles, and fisheries. A final section identifies information gaps, offers a conservation framework, and makes recommendations for preserving the biodiversity of this complex and special ecosystem. Over seventy years of literature on the Laguna Madre and surrounding environments has been synthesized here. With 150 figures and illustrations, the book is the first to take a broad and comprehensive look at both the Texan and Tamaulipan Laguna Madre. For scientists, conservationists, resource managers, and policy makers involved in the future of the Texas and Mexico coasts, the value of this book is clear. And coastal residents, birders, anglers, and nature lovers who want to learn about and take care of the Laguna Madre will find this to be an indispensable guide.
