Ambient air concentrations of PCDDs, PCDFs, coplanar PCBs, and PAHs at the Mississippi Sandhill Crane National Wildlife Refuge, Jackson County, Mississippi Ambient air concentrations of PCDDs, PCDFs, coplanar PCBs, and PAHs at the Mississippi Sandhill Crane National Wildlife Refuge, Jackson County, Mississippi
Our objective was to determine the levels of selected airborne contaminants in ambient air at the Mississippi Sandhill Crane National Wildlife Refuge, Mississippi, that might be affecting the health of endangered cranes living there. Two high-volume air samplers were operated at separate locations on the Refuge during May–September 1991. The sampling media were micro-quartz filters in...

Alternative tissue analysis method developed for organochlorine contaminants in aquatic organisms Alternative tissue analysis method developed for organochlorine contaminants in aquatic organisms
The exposure of aquatic life to organochlorine contaminants has been investigated during the past two decades because of human and ecosystem health concerns related to the bioaccumulation of hazardous, lipophilic substances. The toxic effects of polychlorodibenzo-12-dioxins and polychlorinated biphenyls (PCBs) are well known, and recent evidence also suggests that low level exposure to...

Instrument packages to study long-term sediment transport processes in a shallow bay Instrument packages to study long-term sediment transport processes in a shallow bay
Pressure and near-surface and near-bottom measurements of current, temperature, salinity and light transmission were required in Mobile Bay, a 3 m deep estuary on the Gulf of Mexico. This environment presented several obstacles to obtaining long term observations. Boat traffic, soft estuary bottom, heavy biofouling, rapid sample rates and large data storage were overcome by using...

Flow cytometry for monitoring contaminant exposure in black-crowned night-herons Flow cytometry for monitoring contaminant exposure in black-crowned night-herons
The flow cytometry method (FCM) was employed to determine cellular DNA content of black-crowned night-heron (Nycticorax nycticorax) embryos and 10-day-old chicks collected at sites differing in types of chemical contamination. The coefficient of variation of DNA content (CV) in blood collected from embryos suggested cytogenetic damage at a site in Louisiana known to be contaminated with...

Mourning dove population trend estimates from Call-Count and North American Breeding Bird Surveys Mourning dove population trend estimates from Call-Count and North American Breeding Bird Surveys
The mourning dove (Zenaida macroura) Call-count Survey and the North American Breeding Bird Survey provide information on population trends of mourning doves throughout the continental United States. Because surveys are an integral part of the development of hunting regulations, a need exists to determine which survey provides precise information. We estimated population trends from 1966...

Waterbird use of saltmarsh ponds created for open marsh water management Waterbird use of saltmarsh ponds created for open marsh water management
Open Marsh Water Management (OMWM) as an alternative to pesticides for mosquito control in saltmarshes along the Atlantic Coast has created debate among biologists. We designed an experiment to determine waterbird (American black duck [Anas rubripe]) and other waterfowl, wading birds, shorebirds, gulls, and terns) use (during daylight) of ponds created for mosquito control compared with...

Undernutrition and serum and urinary urea nitrogen of white-tailed deer during winter Undernutrition and serum and urinary urea nitrogen of white-tailed deer during winter
Direct, practical means of assessing undernutrition in deer (Odocoileus spp.) and other ungulates during winter are needed in areas of research and management. We examined the relationship between mass loss and serum urea nitrogen (SUN) and urinary urea nitrogen:creatinine (U:C) in captive white-tailed deer (O. virginianus). During 4 February-5 May 1988, we maintained 7 adult white...
