A warbler in trouble: Dendroica cerulea A warbler in trouble: Dendroica cerulea
The Cerulean Warbler, like other Neotropical migrants, has suffered extensive loss of breeding habitat during the past century. It differs from many other migrants in its preference for mature floodplain forest with tall trees, a habitat that has become scarce over much of the warbler's original nesting range. Sensitivity to fragmentation within remaining suitable tracts places this...

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...

Weaning in an Arctic wolf pack: Behavioral mechanisms Weaning in an Arctic wolf pack: Behavioral mechanisms
If behavioral mechanisms controlling suckling have been shaped by parent-offspring conflict in the ultimate sense, then proximate behavioral determinants of conflict should occur throughout lactation, with greatest intensity in the terminal phase, and offspring should have tactics for overcoming parental resistance. We observed the weaning process in a habituated wild wolf pack (Canis...
