Following Tetraploidy In Maize, A Short Deletion Mechanism Removed Genes Preferentially From One Of The Two Homeologs, Margaret R. Woodhouse, James C. Schnable, Brent S. Pedersen, Eric Lyons, Damon Lisch, Shabarinath Subramaniam, Michael Freeling
Department of Agronomy and Horticulture: Faculty Publications
Previous work in Arabidopsis showed that after an ancient tetraploidy event, genes were preferentially removed from one of the two homeologs, a process known as fractionation. The mechanism of fractionation is unknown. We sought to determine whether such preferential, or biased, fractionation exists in maize and, if so, whether a specific mechanism could be implicated in this process. We studied the process of fractionation using two recently sequenced grass species: sorghum and maize. The maize lineage has experienced a tetraploidy since its divergence from sorghum approximately 12 million years ago, and fragments of many knocked-out genes retain enough sequence similarity …

Fragaria Species Grown In A Greenhouse Cropping System Chemigated By Phosfite® And Bacillus® In Subsidence Of Phytophthora Fragariae And Verticillium Dahliae, Russell L. Morgan
Earth and Soil Sciences
Strawberry yields depend directly on infestation of Phytophthora fragariae and Verticillium dahliae in correspondance to the use of Phosfite and Bacillus. The objective is to find understanding of newly administered techniques in prevention of Phytophthora fragariae and Verticillium dahliae and prohibiting the use of Methyl Bromide. Application of Phosfite and Bacillus on patented Fragariae species to identify utilization of P and ZN forms and their aid in prevention of Phytophthora and Verticillium species. In the Plots on the western bench the developmental symptoms of PRR disease were absent within all infested soil containers containing the FHS-1 crop. In the plots …

Seed Production And Maturation Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser
The Prairie Naturalist
A population of threatened western prairie fringed orchid (Platanthera praeclara) was selected in 2004 on the Sheyenne National Grassland in southeastern North Dakota to study seed production and maturation for future use in population viability modeling. We randomly collected 30 seed capsules from the population under a permit from the U.S. Fish and Wildlife Service to: 1) identify capsule parameters that might be correlated with seed number and viability, 2) estimate an appropriate sample size to obtain accurate seed production estimates, 3) quantify seed production and viability per seed capsule, and 4) document temporal patterns in seed embryo …

Cattle Grazing Reduces Survival And Reproduction Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser
The Prairie Naturalist
QuantifYing impacts of livestock grazing and prairie management strategies on the threatened western prairie' fringed orchid (Platanthera praeclara) is difficult due to the erratic appearance of the orchid above-ground. We monitored above-ground survival of orchids from flowering to mature seed capsule production, comparing plant height, flower numbers, and seed capsule numbers from 2002-2004 in rotationally grazed pastures and non-grazed sites. Orchid survival differed significantly between grazed and non-grazed pastures, with the proportion of plants surviving from flower to capsule production consistently lower in grazed pastures. Mean orchid survival in grazed and non-grazed areas was 40% and 87%, respectively. …

Channel Catfish Diets Include Substantial Vegetation In A Missouri River Reservoir, Jonah D. Dagel, Melissa R. Wuellner, David W. Willis
The Prairie Naturalist
Channel catfish (Ictalurus punctatus) are native to Lake Sharpe, a Missouri River mainstem reservoir, and are common in angler catches. Channel catfish growth has declined since the formation of the reservoir in 1963. Mean lengths at time of capture for channel catfish ages 9, 10, II, and 12 have decreased by 69, 55, 115, and 21S mm, respectively, since impoundment. The objective of this study was to document monthly food habits of channel catfish throughout the growing season (May-August) in Lake Sharpe to assess potential effects of diet on growth. Although channel catfish consumed both macro invertebrates and …

Observations Of Little Blue Herons Nesting In North Dakota, And An Instance Of Probable Natural Hybridization Between A Little Blue Heron And A Cattle Egret, Alisa J. Bartos, Lawrence Igl, Marsha A. Sovada
The Prairie Naturalist
The little blue heron (Egretta caerulea) is native to North America and most commonly breeds along the coast of the southeastern United States and the Gulf of Mexico through Central America and into South America (Rodgers and Smith 1995). In North America, little blue herons rarely nest outside their coastal range. However, nesting has been documented at several locations in the northern plains including Brown, Kingsbury, and Charles Mix counties, South Dakota (Naugle et al. 1996, Tallman et al. 2002); Pope County, Minnesota (Green and Janssen 1975); and possibly in southeastern Saskatchewan (Nero and Lein 1971, Smith et al. 1996). …

Bat Survey Along The Missouri River In Central South Dakota, Alyssa M. Kiesow, Joshua A. Kiesow
The Prairie Naturalist
ats are efficient predators of night-flying insects (Whitaker 1993), particularly in urban, agricultural, and forested areas in South Dakota (Kiesow 2004). In South Dakota, 6 bat species are considered rare and presently monitored by the South Dakota Natural Heritage Program (SDNHP; South Dakota Natural Heritage Program 2002). Because bats serve a vital ecosystem function there is an increased need to conserve bats and their habitats. Hence, the objectives of this project were to determine bat species richness along the Missouri River in central South Dakota. We conducted surveys of bats using mist-nets and acoustic detection from early May to early …

Use Of Late Season Standing Corn By Female White-Tailed Deer In The Northern Great Plains During A Mild Winter, Troy W. Grovenburg, Christopher N. Jacques, Christopher C. Swanson, Robert W. Klaver, Jonathan Jenks
The Prairie Naturalist
Winter habitat and resource use of white-tailed deer (Odocoileus virginianus) have been studied extensively throughout their northern range. However, limited information exists on deer use of late season standing corn. We evaluated standing corn use by female white-tailed deer on winter range in north-central South Dakota during winter 2005-2006. Results indicate that cover type selection occurred at the population (P < 0.001) and home range (P < 0.001) levels. PopUlation level analysis indicated selection for standing corn (vi> = 4.31) and Conservation Reserve Program (CRP) grasslands (vi> = 2.81). Similarly, at the home range level, deer selected for standing corn (vi> = 1.35) and CRP grasslands (vi> = 1.44). Deer disproportionately increased use of standing corn and CRP …
