A Survey Of Carrion And Burying Beetles (Coleoptera:Silphidae) In Mchenry County, Illinois, David Suhrbur

Masters Theses

This study compared the occurrence of beetles in the family Silphidae using historical collection records with that of field collections from five different sites within McHenry County. The five sites include: Glacial Park, Woodstock, Silver Creek, Rush Creek, and Coral Woods. Historically, 11 known silphid species have been found in McHenry County, compared with seven species found during this study' collection period.

Percentages of silphid species at each site was calculated, as well as total number of individuals sampled, and two indices of diversity (Shannon-Weiner and Simpson's) were applied to both current and historical collection data. The historical collection (when …

Impact Of Carbon Sources On Growth And Oxalate Synthesis By The Phytopathogenic Fungus Sclerotinia Sclerotiorum, Bryan Culbertson, Jaymie Krone, Erastus Gatebe, Norbert Furumo, Steven Daniel

Faculty Research & Creative Activity

The impact of various supplemental carbon sources (oxalate, glyoxylate, glycolate, pyruvate, formate, malate, acetate, and succinate) on growth and oxalate formation (i.e., oxalogenesis) by Sclerotinia sclerotiorum was studied. With isolates D-E7, 105, W-B10, and Arg-L of S. sclerotiorum, growth in an undefined broth medium (0.1% soytone; pH 5) with 25 mM glucose and 25 mM supplemental carbon source was increased by the addition of malate and succinate. Oxalate accumulation occurred in the presence of glucose and a supplemental carbon source, with malate, acetate, and succinate supporting the most oxalate synthesis. With S. sclerotiorum Arg-L, oxalate-to-biomass ratios, an indicator of oxalogenic …

Dessication Stress, Steven C. Hand, Michael A. Menze

Faculty Research & Creative Activity

The threat of desiccation for organisms inhabiting the intertidal zone occurs during emersion at low tides or when organisms are positioned in the high intertidal zone, where wetting occurs primarily by spring tides, storm waves, and spray. Drying due to evaporative water loss is the most common mechanism for dehydration, although during winter in northern temperate regions freezing can also occur, which reduces the liquid water in extracellular fluids and can lead to intracellular dehydration in multicellular organisms. Freezing tolerance has been reported and characterized for a number of intertidal invertebrates, including gastropods such as an air-breathing snail and a …

Floral Biology Of Physaria Ludoviciana (Brassicaceae), A Plant Rare To The Midwest, Ann E. Claerbout, Janice M. Coons, Henry R. Owen, Kenneth R. Robertson

Faculty Research & Creative Activity

Physaria ludoviciana (Brassicaceae) is rare in Illinois, Minnesota, and Wisconsin. Environmental effects on floral development are unclear. Both self-compatibility and self-incompatibility occur within Physaria species. Objectives were to describe flowers, to determine how photoperiod affects flower development, and to predict whether flowers are self-compatible or self-incompatible. For photoperiods, greenhouse-grown plants were placed in either 16 or 8 hr photoperiods. Inflorescences and open flowers were counted weekly. For pollination, flowers were self-pollinated or cross-pollinated. Plants developed inflorescences after 20 and 28 d in long and short days, respectively. Inflorescences/plant increased for both photoperiods throughout the study. In short days, plants produced …

Mammalian Cell Cytotoxicity Analysis Of Soybean Rust Fungicides, Steven L. Daniel, G. L. Hartman, E. D. Wagner, M. J. Plewa

Faculty Research & Creative Activity

The identification of soybean rust, caused by Phakopsora

pachyrhizi H. Sydow & Sydow, in the southern United

States in November 2004 (Schneider et al. 2005 ), in the

Midwest in 2006 (Hartman et al. 2007 ), and elsewhere has

increased the concerns of the impact of the pathogen on US

soybean production (Miles et al. 2007 ). The rapid spread of

P. pachyrhizi and its potential to cause severe yield losses

makes this among the most destructive foliar diseases of

soybean. Yield losses of 20%–60% were reported in Asia,

with losses of 80% reported from experimental plots in

Taiwan (Hartman …
