Green-Ampt Infiltration Parameters In Riparian Buffers, L. M. Stahr, Dean E. Eisenhauer, M. J. Helmers, Mike Dosskey, Thomas G. Franti

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Riparian buffers can improve surface water quality by filtering contaminants from runoff before they enter streams. Infiltration is an important process in riparian buffers. Computer models are often used to assess the performance of riparian buffers. Accurate prediction of infiltration by these models is dependent upon accurate estimates of infiltration parameters. Of particular interest here are Green-Ampt infiltration parameters, satiated hydraulic conductivity (K_o) and wetting front suction (h_f). The objectives of this research were to (i) modify the Smith sorptivity procedure so that it can be used to estimate Green-Ampt infiltration parameters, (ii) Determine the relative …

A New Species Of Pelecitus (Filarioidea: Onchocercidae) From The Endnagered Tehuantepec Jackrabbit Lepus Flavigularis, F. Agustin Jimenez-Ruiz, Scott Lyell Gardner, Fernando A. Cervantes, Consuelo Lorenzo

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Pelecitus meridionaleporinus n. sp. from the Tehuantepec jackrabbit is described. The new species differs from Pelecitus helicinus (Molin, 1860) in having delicate transverse striations, a salient vulva, and a readily apparent preesophageal ring; P. helicinus has teardrop cells around the vulva, which are lacking in the species presently described. The new species is different from Pelecitus scapiceps (Leidy, 1886) in having the vulva anterior to the esophageal–intestinal junction and wider lateral alae. Pelecitus scapiceps is found in the tarsal bursa of the hind feet of lagomorphs, whereas P. helicinus is found around tendons of legs and feet of birds. Pelecitus …

Activity Of Gut Proteinases From Cry1ab-Selected Colonies Of The European Corn Borer, Ostrinia Nubilalis (Lepidoptera: Crambidae), Herbert A. A. Siqueira, Kenneth Nickerson, Daniel Moellenbeck, Blair D. Siegfried

Department of Entomology: Faculty Publications

Susceptibility to the Cry1Ab protoxin and toxin from Bacillus thuringiensis (Berliner) and activity of gut proteinases were assessed in both susceptible and Cry1Ab-selected colonies of European corn borer, Ostrinia nubilalis (Hübner). Resistance in two different selected colonies was at least 6- and 15-fold for the Cry1Ab protoxin and 108- and 484-fold for the Cry1Ab toxin. Activities of trypsin-like, chymotrypsin-like and elastase-like proteinases were variable among the colonies tested and not indicative of a major contribution to Cry1Ab resistance. Activation of the 130-kDa Cry1Ab protoxin occurred rapidly in all colonies, with no apparent differences among colonies. In addition, there were no …

Capillary Liquid Chromatography Using Micro Size Particles, Yanqiao Xiang

Theses and Dissertations

High speed and/or high efficiency separations can be realized using small particles (~ 1 µm) in liquid chromatography (LC). However, due to the large pressure drop caused by small particles, conventional LC pumping systems cannot satisfy the pressure requirements needed to drive the mobile phase through the column. Use of ultrahigh pressure, elevated temperature, or both can overcome these pressure limitations and allow the use of very small particles for high speed and/or high efficiency separations.

In this dissertation, the use of ultrahigh pressures with and without elevated temperatures in capillary LC is described. Very fast separations of various samples …

Simulating The Dynamics Of Linear Forests In Great Plains Agroecosystems Under Changing Climates, Qinfeng Guo, James R. Brandle, Michele M. Schoeneberger, D. Buettner

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Most forest growth models are not suitable for the highly fragmented, linear (or linearly shaped) forests in the Great Plains agroecosystems (e.g., windbreaks, riparian forest buffers), where such forests are a minor but ecologically important component of the land mosaics. This study used SEEDSCAPE, a recently modified gap model designed for cultivated land mosaics in the Great Plains, to simulate the effects of climate change on the dynamics of such linear forests. We simulated the dynamics of windbreaks with different initial planting species richness and widths flight changes as the selected resulting factor) using current climate data and nested regional …

A New Species Of Oryzomys (Rodentia: Muridae) From An Isolated Pocket Of Cerrado In Eastern Bolivia, Daniel M. Brooks, R. Julieta Vargas M., Teresa Tarifa, Hugo Aranibar, José Manuel Rojas

University of Nebraska State Museum: Mammalogy Papers

Reliable characterization of a species is an essential step toward eventual reconstruction of phylogenetic alliances among related taxa (Musser et al. 1998). Although characterization of species within the genus Oryzomys has met with some confusion in the past, significant work has taken place to help better define specific limits within this group (Musser et al. 1998; Bonvicino and Moreira 2001; Langguth and Bonvicino 2002).

In spite of several recent surveys performed in the eastern Bolivian Panhandle (Emmons 1993; Taber et al. 1997; Brooks et al. 2002), our knowledge of the mammalian fauna in this region is still incomplete, and further …

A Modeling Study Of Benthic Detritus Flux's Impacts On Heterotrophic Processes In Lake Michigan, Changsheng Chen, Lixia Wang, Jianhua Qi, Hedong Liu, Judith Wells Budd, David J. Schwab, Dmitry Beletsky, Henry Vanderploeg, Brian Eadie, Thomas Johengen, James Cotner, Peter J. Lavrentyev

Biology Faculty Research

Effects of sediment resuspension-induced benthic detrital flux on the heterotrophic part of the microbial food web in Lake Michigan were examined using a three-dimensional (3-D) coupled biological and physical model. The model was driven by the realistic meteorological forcing observed in March 1999. Wind-induced surface wave dynamics were incorporated into the physical model to generate the bottom flux. The model-generated benthic detrital flux was assumed to be proportional to the difference between model-calculated and critical stresses at the bottom. The model results indicate that detrital flux at the bottom was a key factor causing a significant increase of phosphorus and …
