Nonfish Prey Of Wintering Bald Eagles In Lilinois, Given Harper, D. Scott Hopkins, Thomas C. Dunston Nov 1988

Nonfish Prey Of Wintering Bald Eagles In Lilinois, Given Harper, D. Scott Hopkins, Thomas C. Dunston

Given Harper

Many Bald Eagles (Haliaeetus leucocephalus) winter in Illinois (Fawks 1979), where they feed primarily on fish (e.g., Southern 1966, Fischer 1982, Harper 1983). However, few reports have been published documenting their use of mammalian and avian prey in the midwestern United States (Lingle and Krapu 1986, Stalmaster 1987). This paper describes the almost exclusive use of nonfish prey in an upland population of Bald Eagles, and discusses related management implications.

Trypanosoma Lewisi: Effects Of Trace Metal Contaminants On Immunological Responses, Yvonne Hogan, Clarence Lee Oct 1988

Trypanosoma Lewisi: Effects Of Trace Metal Contaminants On Immunological Responses, Yvonne Hogan, Clarence Lee

Clarence Lee

The effects of trace metal contaminants (lead, cadmium, and mercury) on the immunologic responses of rats infected with Trypanosoma lewisi were investigated to determine whether chronic exposures to subclinical levels of these metals have adverse effects on the host's ability to respond to an infective agent.Earlier and higher levels of parasitemia were detected in animals exposed to cadmium, lead, and mercury. The variability in length of trypanosome cells in metal-exposed animals became constant at a later time and persisted for a longer time, indicating a delay in antibody synthesis. Serum levels of IgG and IgM were increased in infected animals …
