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...

Effects of salinity on striped bass eggs and larvae from the Savannah River, Georgia Effects of salinity on striped bass eggs and larvae from the Savannah River, Georgia
Operation of a tide gate installed in the Savannah River by the U.S. Army Corps of Engineers to reduce dredging activities increased salinities upstream in important spawning habitat for striped bass Morone saxatilis. To assess the effects of salinity on survival and growth of striped bass at early life stages, newly fertilized eggs and 48‐h‐posthatch larvae were exposed to serial...

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...

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...

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...

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...

Anticholinesterase exposure of white-winged doves breeding in lower Rio Grande valley, Texas Anticholinesterase exposure of white-winged doves breeding in lower Rio Grande valley, Texas
We studied exposure of breeding white-winged doves (Zenaida asiatica) to anticholinesterase compounds (organophosphorus and carbamate pesticides) in the Lower Rio Grande Valley (LRGV), Texas. Widespread use of organophosphorus pesticides and dove population declines prompted the study. We collected breeding adult doves in May and July 1991 (n = 28) and July 1992 (n = 33) at 6 locations...

Environmental contaminants in nonviable eggs of the endangered Mississippi sandhill crane (Grus canadensis pulla) Environmental contaminants in nonviable eggs of the endangered Mississippi sandhill crane (Grus canadensis pulla)
Our objectives were to determine if concentrations of environmental pollutants and microbial contamination in nonviable eggs of the endangered Mississippi sandhill crane (Grus canadensis pulla) contributed to egg failure. Six eggs collected in 1990 and four in 1991 contained only background levels of organochlorine pesticides and polychlorinated biphenyls (PCBs), and tests for microbial

Habitat use by an endangered riverine fish and implications for species protection Habitat use by an endangered riverine fish and implications for species protection
We investigated habitat specificity of the amber darter (Percina antesella Williams & Etnier 1977), an imperiled fish from restricted portions of 2 rivers in the southeastern United States. Foraging amber darters occupied a narrow range of riffle habitat, consistently avoiding areas 20 cm deep and with velocity 10 cm. s−1 near the substrate, occupying areas with cobble or gravel...
