Seroepidemiology of leptospirosis in Minnesota wolves Seroepidemiology of leptospirosis in Minnesota wolves
Serum samples (n = 457) from wolves (Canis lupus) in northern Minnesota were collected from 1972 through 1986 and were tested for antibodies against Leptospira interrogans using a microtiter agglutination test. Twelve serovars included in the study were: australis, autumnalis, ballum, bataviae, bratislava, canicola, copenhageni, grippotyphosa, hardjo, pomona, pyrogenes, and tarassovi...

Accumulation of trace elements and organochlorines by surf scoters wintering in the Pacific northwest Accumulation of trace elements and organochlorines by surf scoters wintering in the Pacific northwest
Selenium, cadmium, mercury, copper, manganese, zinc, aluminum, lead, PCBs and DDE were accumulated by segments of the surf scoter (Melanitta perspicillata) population that winters in the Pacific Northwest, but whether the uptake occurred on breeding and/or wintering grounds was uncertain for some contaminants. Surf scoters collected in Puget Sound and San Francisco Bay (in another study)...

Atmospheric organochlorine pollutants and air-sea exchange of hexachlorocyclohexane in the Bering and Chukchi Seas Atmospheric organochlorine pollutants and air-sea exchange of hexachlorocyclohexane in the Bering and Chukchi Seas
Organochlorine pesticides have been found in Arctic fish, marine mammals, birds, and plankton for some time. The lack of local sources and remoteness of the region imply long-range transport and deposition of contaminants into the Arctic from sources to the south. While on the third Soviet-American Joint Ecological Expedition to the Bering and Chukchi Seas (August 1988), high-volume air...

Subchronic hepatotoxicity of selenomethionine ingestion in mallard ducks Subchronic hepatotoxicity of selenomethionine ingestion in mallard ducks
Twoyearold male mallards (Anas platyrhynchos) received a control diet (0.2 ppm Se) or diets containing 1, 2, 4, 8, 16, or 32 ppm Se as selenomethionine for 14 wk. Se accumulated readily in the liver in a dosedependent manner, reaching a mean concentration of 29 ppm (wet weight) in the 32 ppm group. Dietary Se of 2 ppm or greater increased plasma glutathione peroxidase activity. Mortality...

Use of Wetland Habitats by Selected Nongame Water Birds in Maine Use of Wetland Habitats by Selected Nongame Water Birds in Maine
We examined the use of 87 palustrine and lacustrine wetlands by nongame water birds in central and eastern Maine using 3,527 h of observation (1,501 visits) made during April-August, 1977-85. Wetlands used by 15 species of water birds were distinguished from those not used, according to 20 habitat features. The species were the common loon (Gavia immer) , pied-billed grebe (Podilymbus...

Compendium of crane behavior. Part 1: Individual (nonsocial) behavior Compendium of crane behavior. Part 1: Individual (nonsocial) behavior
This paper provides the organizational framework, nomenclature, and abbreviated descriptions for all conspicuous nonsocial behavioral units for all 15 species of crane. We present eight generalized functional classes of behavior. These classes include about 90 discrete motor patterns that constitute the nonsocial repertoire of all cranes. We present this compendium to facilitate...

Breeding Bird Survey and bird banding data: Applications to raptor research and management Breeding Bird Survey and bird banding data: Applications to raptor research and management
The Breeding Bird Survey (BBS) and Bird Banding Laboratory (BBL) are sources of information for raptor biologists. The BBS has been conducted each year since 1966 in the United States and Canada; historical bird banding records extend back to the early 20th century. BBS data can be used to document population trends and breeding distributions of many bird species. Banding data are...

Response of sago pondweed, a submerged aquatic macrophyte, to herbicides in three laboratory culture systems Response of sago pondweed, a submerged aquatic macrophyte, to herbicides in three laboratory culture systems
The phytotoxicity of atrazine, paraquat, glyphosate, and alachlor to sago pondweed (Potamogeton pectinatus), a submerged aquatic macrophyte, was tested under three types of laboratory culture conditions. In each case, tests were conducted in static systems, the test period was four weeks, and herbicide exposure was chronic, resulting from a single addition of herbicide to the test...
