Seroprevalence of Lyme disease in gray wolves from Minnesota and Wisconsin Seroprevalence of Lyme disease in gray wolves from Minnesota and Wisconsin
To determine the seroprevalence of Lyme disease in gray wolves (Canis lupus) from various counties of Minnesota and Wisconsin (USA), 589 serum samples were collected from 528 wolves from 1972 to 1989. An indirect fluorescent antibody (IFA) test was used to detect the presence of antibodies against Borrelia burgdorferi. Titers of greater than or equal to 1:100 were considered positive...

Four new species of frogs and one new species of snake from the Chapare region of Bolivia, with notes on other species Four new species of frogs and one new species of snake from the Chapare region of Bolivia, with notes on other species
We report on a collection of 74 frogs, 11 lots of frog eggs or tadpoles, and two snakes collected from the Chapare Region in the yungas of the eastern Andean Cordillera de Cochabamba, Bolivia. Collecting localities range from approximately 300 m to >3200 m in elevation. The specimens pertain to 23 species, probably 10 of which are undescribed. We describe four new species of frogs, one...

Prevalence of antibody titers to leptospira spp. in Minnesota white-tailed deer Prevalence of antibody titers to leptospira spp. in Minnesota white-tailed deer
Serum samples (n = 204) from 124 white-tailed deer (Odocoileus virginianus) in northeastern Minnesota (USA) were collected from 1984 through 1989 and tested for antibodies to six serovars of Leptospira interrogans (bratislava, canicola, grippotyphosa, hardjo, icterohemorrhagiae, and pomona) using a microtiter agglutination test. Eighty-eight (43%) sera were positive at greater than or...

Comparative productivity of American black ducks and mallards nesting on Chesapeake Bay Islands Comparative productivity of American black ducks and mallards nesting on Chesapeake Bay Islands
The authors estimated laying dates, clutch sizes, and nest success rates of sympatrically breeding populations of American black ducks (Anas rubripes ) and mallards (Anas platyrhynchos ) on Chesapeake Bay islands between 1986 and 1989. Neither average laying date nor clutch size differed between black ducks and mallards. Nest success rates were higher for mallards in 2 of 4 years, but...

Assessing effects of pesticides on amphibians and reptiles: status and needs Assessing effects of pesticides on amphibians and reptiles: status and needs
Growing concern about the decline of certain amphibian populations and for conservation of amphibians and reptiles has led to renewed awareness of problems from pesticides. Testing amphibians and reptiles as a requirement for chemical registration has been proposed but is difficult because of the phylogenetic diversity of these groups. Information from the literature and research may...
