Managing birds and controlling aircraft in the Kennedy Airport-Jamaica Bay Wildlife Refuge complex: The need for hard data and soft opinions Managing birds and controlling aircraft in the Kennedy Airport-Jamaica Bay Wildlife Refuge complex: The need for hard data and soft opinions
During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we...

Nest survival of forest birds in the Mississippi Alluvial Valley Nest survival of forest birds in the Mississippi Alluvial Valley
In the Mississippi Alluvial Valley, flood control has led to a drastic reduction in the area of forest habitat and altered the patchwork of forest cover types. Silvicultural management of the remaining fragmented forests has changed to reflect the altered hydrology of the forests, current economic conditions of the area, and demand for forest products. Because forest type and...

Nest poaching in Neotropical parrots Nest poaching in Neotropical parrots
Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortality due to nest poaching in 23 studies of Neotropical parrots, representing 4024 nesting attempts in 21 species and 14 countries. We also examined how poaching rates vary with geographic region...

Failure of tetracycline as a biomarker in batch-marking juvenile frogs Failure of tetracycline as a biomarker in batch-marking juvenile frogs
Recent widespread amphibian declines call for better techniques to assess population dynamics. Tetracycline as a biomarker in capture-recapture studies is one technique used successfully in fish, reptiles, and mammals. A two-phase experimental study was conducted to evaluate tetracycline as a biomarker in green frogs (Rana clamitans) and pickerel frogs (Rana palustris). In the first...

Polycyclic aromatic hydrocarbons, aliphatic hydrocarbons, trace elements and monooxygenase activity in birds nesting on the North Platte River, Casper, Wyoming, USA Polycyclic aromatic hydrocarbons, aliphatic hydrocarbons, trace elements and monooxygenase activity in birds nesting on the North Platte River, Casper, Wyoming, USA
Tree swallow (Tachycineta bicolor) and house wren (Troglodytes aedon) eggs and chicks were collected near a refinery site on the North Platte River, Casper, Wyoming, USA and at a reference site 10 km upstream. Total polycylic aromatic hydrocarbon (PAH) concentrations in swallow and wren chicks were higher at the refinery site than at the reference site. Polycylic aromatic hydrocarbon

Monitoring of biological diversity in space and time Monitoring of biological diversity in space and time
Monitoring programmes are being used increasingly to assess spatial and temporal trends of biological diversity, with an emphasis on evaluating the efficiency of management policies. Recent reviews of the existing programmes, with a focus on their design in particular, have highlighted the main weaknesses: the lack of well-articulated objectives and the neglect of different sources of...

Pesticides are involved with population declines of amphibians in the California Sierra Nevadas Pesticides are involved with population declines of amphibians in the California Sierra Nevadas
Several species of frogs and toads are in serious decline in the Sierra Nevada Mountains of California. These species include the threatened red-legged frog ( Rana aurora ), foothill yellow-legged frog ( R. boylii ), mountain yellow-legged frog ( R. muscosa ), Cascades frog ( Rana cascadae ), western toad ( Bufo boreas ) and Yosemite toad ( B. canorus ). For many of these species current

Investigation of eggshell thickness and biochemical indicators of contaminant exposure in Great Blue Herons(Ardea herodias) from Mason Neck National Wildlife Refuge Investigation of eggshell thickness and biochemical indicators of contaminant exposure in Great Blue Herons(Ardea herodias) from Mason Neck National Wildlife Refuge
Mason Neck National Wildlife Refuge supports the largest great blue heron (Ardea herodias) rookery in the State of Virginia. The presence of bioaccumulative compounds such as polychlorinated biphenyls and DDT in fish collected from the Potomac River and tidal tributaries along the Refuge led to this study. The objective was to determine if there were any indications of pollutant-induced...

Fate of the survivors of the 1995 and 1996 Arizona trucking migrations of costume-reared greater sandhill cranes Fate of the survivors of the 1995 and 1996 Arizona trucking migrations of costume-reared greater sandhill cranes
In 1995 and 1996, we trained 2 groups of costume-reared greater sandhill cranes (Grus canadensis tabida) (10 in 1995, 14 in 1996) to follow a truck. Thereafter we led 10 in 1995 and 12 in 1996 from Garland Prairie, northern Arizona, to the Buenos Aires National Wildlife Refuge, southern Arizona (ca. 620 km). These techniques were being developed to create additional, disjunct populations...

Differences in oxidative stress between young Canada geese and mallards exposed to lead-contaminated sediment Differences in oxidative stress between young Canada geese and mallards exposed to lead-contaminated sediment
Lead (Pb) exposure results in an increase in tissue lipid peroxides and variation in glutathione (GSH) concentrations, which can be related to peroxidative damage of cell membranes in Pb-poisoned animals. Species and individual variation in sensitivity to Pb poisoning among animals may be due to differential resistance to oxidative stress. The effects of oxidative stress caused by Pb...
