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

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

Scholarship

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.

Effect Of Conidia Germination On Infection Of Brown Planthopper (Bph) By Insect Fungi, M. C. Rombach, R. M. Aguda, Donald W. Roberts Dec 1988

Effect Of Conidia Germination On Infection Of Brown Planthopper (Bph) By Insect Fungi, M. C. Rombach, R. M. Aguda, Donald W. Roberts

Biology Faculty Publications

Conidia of insect fungi actively invade BPH [brown planthopper]. After a conidium lands on the insect cuticle, germination takes about 8 to 16 h, depending on the temperature and relative humidity. After the germination, tuber is formed, the conidium produces specific chitinase enzymes to dissolve the insect cuticle. This allows the fungus to enter the insect body cavity, where further fungus growth occurs. At the end of the infection cycle, the mycelium sporulates on the outside of the insect. Conidia produced on the cadaver can infect healthy BPH initiating epizootics of the fungus. To test infection, 50 adult alate BPH ...

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Of 35 tuco-tucos (Ctenomys opimus) collected in Bolivia, South America, 31 (88%) had eimerian oocysts in their feces at the time they were examined. Eighteen (58%) of the 31 infected animals were concurrently infected with 2 or 3 eimerian species. Four species of Eimeria were recovered and are described as new species based on the characteristics of sporulated oocysts. Oocysts of Eimeria granifera n. sp. were ellipsoidal, 21.1 x 17.2 (15-26 x 11-20), [micro]m with sporocysts ovoidal, 11.3 x 7.1 (8-14 x 5-9), [micro]m.

Generic Advertising Without Supply Control: Models And Public Policy Issues, Dermot J. Hayes, Helen H. Jensen Dec 1988

Generic Advertising Without Supply Control: Models And Public Policy Issues, Dermot J. Hayes, Helen H. Jensen

CARD Working Papers

Both producers and consumers may respond to the use of producer contributions to fund commodity promotion. The microeconomic foundation is laid for evaluating generic promotion campaigns where government is involved, supply is uncontrolled, and markets are close to saturation. The recent legislation enabling beef and pork promotion provides an application for the model.


Influence Of Env And Long Terminal Repeat Sequences On The Tissue Tropism Of Avian Leukosis Viruses, David W. Brown, Harriet L. Robinson Dec 1988

Influence Of Env And Long Terminal Repeat Sequences On The Tissue Tropism Of Avian Leukosis Viruses, David W. Brown, Harriet L. Robinson

Open Access Publications by UMMS Authors

Adsorption and penetration of retroviruses into eucaryotic cells is mediated by retroviral envelope glycoproteins interacting with host receptors. Recombinant avian leukosis viruses (ALVs) differing only in envelope determinants that interact with host receptors for subgroup A or E ALVs have been found to have unexpectedly distinctive patterns of tissue-specific replication. Recombinants of both subgroups were highly expressed in bursal lymphocytes as well as in cultured chicken embryo fibroblasts. In contrast, the subgroup A but not subgroup E host range allowed high levels of expression in skeletal muscle, while subgroup E but not subgroup A envelope glycoproteins permitted efficient replication in ...


The Short Term Effects Of Manganese Toxicity On Isocitrate Dehydrogenase In Wheat & Tobacco, Juergen Pfeiffer Dec 1988

The Short Term Effects Of Manganese Toxicity On Isocitrate Dehydrogenase In Wheat & Tobacco, Juergen Pfeiffer

Masters Theses & Specialist Projects

The short term effects of high manganese levels (80 mg/L) on wheat and tobacco isocitrate dehydrogenase (IDH) activity were compared. The change in activity was then compared to the concentrations of manganese in the tissues.

As the time of manganese exposure increased, the fresh weight IDH activities in wheat and tobacco decreased. In contrast both control groups had similar enzyme activities every 6 hr over the 24 hr test period. The decrease in IDH activity of wheat and tobacco plants in experimental groups seemed to be related to an increase of the manganese in the leaf tissue. The slower ...

Survival Of Escherichia-Coli And Salmonella Spp In Estuarine Environments, Mw Rhodes, Hi Kator Dec 1988

Survival Of Escherichia-Coli And Salmonella Spp In Estuarine Environments, Mw Rhodes, Hi Kator

VIMS Articles

Survival of Escherichia coli and Salmonella spp. in estuarine waters was compared over a variety of seasonal temperatures during in situ exposure in diffusion chambers. Sublethal stress was measured by both selective-versus-resuscitative enumeration procedures and an electrochemical detection method. E. coli and Salmonella spp. test suspensions, prepared to minimize sublethal injury, were exposed in a shallow tidal creek and at a site 7.1 km further downriver. Bacterial die-off and sublethal stress in filtered estuarine water were inversely related to water temperature. Salmonella spp. populations exhibited significantly less die-off and stress than did E. coli at water temperatures of <10°C. Although the most pronounced reductions (ca. 3 log units) in test bacteria occurred during seasonally warm temperatures in the presence of the autochthonous microbiota, 102 to 104 test cells per ml remained after 2 weeks of exposure to temperatures of >15 ...
