Population Biology Of Pumpkinseed In Enemy Swim Lake, South Dakota, Eric J. Weimer, Michael L. Brown
Population Biology Of Pumpkinseed In Enemy Swim Lake, South Dakota, Eric J. Weimer, Michael L. Brown
The Prairie Naturalist
Little information is available regarding the biology and population characteristics of pumpkinseed (Lepomis gibbosus), especially in South Dakota, a state at the western edge of the species native range. South Dakota Department of Game, Fish and Parks summer trap net survey data, collected 1998 to 2003, suggests the Enemy Swim Lake population has low abundance (0.4-2.9 per trap net night) and moderately high size structure (proportional stock density [PSD] ranges between 71 and 91). To further examine the biological characteristics of the Enemy Swim Lake population, pumpkinseed was collected from Indian Bay with trap nets during May 2003. …

Reproductive Development In The Sicklefin Chub In The Missouri And Lower Yellowstone Rivers, Douglas J. Dieterman, Eric Roberts, Patrick J. Braaten, David L. Galat
The Prairie Naturalist
We describe aspects of sicklefin chub (Macrhybopsis meeki) reproductive development from three study areas encompassing greater than 2,700 km of the Missouri and Lower Yellowstone rivers. The sicklefin chub was collected between late July and early October in 1996 and 1997. A total of 193 sicklefin chub was collected and examined for reproductive characteristics. Twenty-nine sicklefin chub were found to be reproductively mature females. Some sicklefin chub matured at age 2, but most matured at age 3 and all matured by age 4. Females first became mature at 70 to 79 mm total length (TL) in the Upper …

Feeding Habitats Of Spring-Migrating Blackbirds In East-Central South Dakota, Richard S. Sawin, George M. Linz, William J. Bleier, H. Jeffrey Homan
The Prairie Naturalist
Between March 27 and April 21, 1998, we monitored blackbird (Icteridae) activity and habitat selection at a migratory staging area in east-central South Dakota. We used fixed-area observation points located within 20 l-km2 circular plots centered on four wetland basins that were used as night roosts. Each roost was surveyed four times, with the surveys spread evenly throughout the blackbird migration. We recorded the number of blackbird flocks, flock size and composition, habitat used, and behavior (e.g., loafing and feeding). Fifty percent (n = 242) of the 482 flocks recorded in the quadrats was observed loafing in trees …

First Record Of The Spurge Hawkmoth As A Pollen Vector For The Western Prairie Fringed Orchid [Notes], Carla R. Jordan, Gerald M. Fauske, Mrion O. Harris, Darla Lenz
The Prairie Naturalist
Identification of pollen vectors is one step in refining management plans for a threatened plant such as the western prairie fringed orchid (Platanthera praeclara Sheviak and Bowles). Pollen vector bionomics, phenology, and ethology must be understood to assess this moth and other potential pollinators relative to orchid reproductive success. Also, the ability of spurge hawkmoth (Lepidoptera: Sphingidae), a recently introduced species, to act as a pollen vector for an obligate prairie plant, the western prairie fringed orchid, in theoretical terms, provides evidence which contradicts long held tenets of one-to-one correspondence between orchids and their pollinators. Further research might shed …

Fire History, Passerine Abundance, And Habitat On A North Dakota Drift Plain Prairie, Timothy J. Ludwick, Robert K. Murphy
The Prairie Naturalist
Prescribed fire is among key tools for restoring and managing prairies in the northern Great Plains, yet there are no published reports of its impacts on grassland passerine birds on native prairie in the Drift Plain, a major physiographic subregion. We examined relationships between prescribed fire history and abundance and habitat of breeding passerines in Drift Plain prairie at Des Lacs National Wildlife National Refuge in northwestern North Dakota. In 2003, we used point counts (n = 79 75 m radius plots) to survey bird abundance on 16 management units that had been prescribe-burned one to three times each …

Estimates Of Breeding Bird Populations In The Sheyenne National Grassland, North Dakota, Mary Ann Cunningham, Douglas Johnson, Daniel N. Svingen
The Prairie Naturalist
We conducted a two-year survey of breeding birds in the Sheyenne National Grassland, North Dakota, to estimate total populations of breeding birds. The Grassland is of interest because it provides wildlife habitat and recreational birding opportunities. Indicated breeding pairs were counted on 100-m wide belt transects during morning surveys from late May to early July in 2002 and 2003. We surveyed approximately 6 to 7% of the Grassland each year. The most abundant species in both years were grasshopper sparrow (Ammodramus savannarum), red-winged blackbird (Agelaius phoeniceus), claycolored sparrow (Spizella pallida), Savannah sparrow (Passerculus …

Effects Of Predator Removal On Upland Nesting Ducks In North Dakota Grassland Fragments, Kristen D. Chodachek, Michael J. Chamberlain
The Prairie Naturalist
Low nest success rates in the Prairie Pothole Region are attributed mainly to changes in the predator community coupled with reductions in availability of suitable nesting cover. We evaluated effects of removal of mammalian predators on pair density and nest success of ducks nesting on 259 ha sites in northeastern North Dakota during 2001 and 2002. We monitored pair density and duck nests on 10 sites with removal and 10 sites without removal. Overall nest success for both years was greater on trapped (53.4%) than nontrapped sites (28.7%). Pair densities were not affected by predator removal, but did increase across …
2006 Vegetation Survey Of The Valentine National Wildlife Refuge, Robert F. Steinauer
2006 Vegetation Survey Of The Valentine National Wildlife Refuge, Robert F. Steinauer
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The Valentine National Wildlife Refuge (VNWR), located in north central Cherry County, was established in 1934. Tolstead (1942) studied the grasslands of northern Cherry County, (including the Valentine National Wildlife Refuge) with a focus on describing the dominant species of grassland types and determining the relationships between vegetation distribution and environmental variables and management practices. Additional studies have been conducted by refuge staff on the effects of management, particularly grazing, on vegetation structure. The purpose of this study was to: (1) document all vascular plant species present on the refuge; (2) collect data on rare plant species and high-quality native …

Snp-Phage – High Throughput Snp Discovery Pipeline, Lakshmi K. Matukumalli, John J. Grefenstette, David L. Hyten, Ik-Young Choi, Perry B. Cregan, Curt P. Van Tassell
Department of Agronomy and Horticulture: Faculty Publications
Background: Single nucleotide polymorphisms (SNPs) as defined here are single base sequence changes or short insertion/deletions between or within individuals of a given species. As a result of their abundance and the availability of high throughput analysis technologies SNP markers have begun to replace other traditional markers such as restriction fragment length polymorphisms (RFLPs), amplified fragment length polymorphisms (AFLPs) and simple sequence repeats (SSRs or microsatellite) markers for fine mapping and association studies in several species. For SNP discovery from chromatogram data, several bioinformatics programs have to be combined to generate an analysis pipeline. Results have to be stored in …
Evaluation Of The Single Kernel Characterization System (Skcs) For Measurement Of Sorghum Grain Attributes, S. R. Bean, O. K. Chung, M. R. Tuinstra, Jeffrey F. Pedersen, J. Erpelding
Evaluation Of The Single Kernel Characterization System (Skcs) For Measurement Of Sorghum Grain Attributes, S. R. Bean, O. K. Chung, M. R. Tuinstra, Jeffrey F. Pedersen, J. Erpelding
Department of Agronomy and Horticulture: Faculty Publications
The single kernel characterization system (SKCS) has been widely used in the wheat industry, and SKCS parameters have been linked to end-use quality in wheat. The SKCS has promise as a tool for evaluating sorghum grain quality. However, the SKCS was designed to analyze wheat, which has a different kernel structure from sorghum. To gain a better understanding of the meaning of SKCS predictions for grain sorghum, individual sorghum grains were measured for length, width, thickness (diameter), and weight by laboratory methods and by the SKCS. SKCS predictions for kernel weight and thickness were highly correlated to laboratory measurements. However, …

Background: Single nucleotide polymorphisms (SNP) constitute more than 90% of the genetic variation, and hence can account for most trait differences among individuals in a given species. Polymorphism detection software PolyBayes and PolyPhred give high false positive SNP predictions even with stringent parameter values. We developed a machine learning (ML) method to augment PolyBayes to improve its prediction accuracy. ML methods have also been successfully applied to other bioinformatics problems in predicting genes, promoters, transcription factor binding sites and protein structures. Results: The ML program C4.5 was applied to a set of features in order to build a SNP classifier …

Alfalfa stems, reed canarygrass, and switchgrass; perennial herbaceous species that have potential as biomass energy crops in temperate regions; were evaluated for their bioconversion potential as energy crops. Each forage species was harvested at two or three maturity stages and analyzed for carbohydrates, lignin, protein, lipid, organic acids, and mineral composition. The biomass samples were also evaluated for sugar yields following pretreatment with dilute sulfuric followed by enzymatic saccharification using a commercial cellulase preparation. Total carbohydrate content of the plants varied from 518 to 655 g kg-1 dry matter (DM) and cellulose concentration from 209 to 322 g kg …

Department of Agronomy and Horticulture: Faculty Publications
Here, we describe two members of the Arabidopsis (Arabidopsis thaliana) Yellow Stripe-Like (YSL) family, AtYSL1 and AtYSL3. The YSL1 and YSL3 proteins are members of the oligopeptide transporter family and are predicted to be integral membrane proteins. YSL1 and YSL3 are similar to the maize (Zea mays) YS1 phytosiderophore transporter (ZmYS1) and the AtYSL2 iron (Fe)-nicotianamine transporter, and are predicted to transport metal-nicotianamine complexes into cells. YSL1 and YSL3 mRNAs are expressed in both root and shoot tissues, and both are regulated in response to the Fe status of the plant. β-Glucuronidase reporter expression, driven by …

The selection of superior adapted cultivars has contributed to the doubling of soybean [Glycine max (L.) Merr.] yields in the USA since 1930. Genetic variation was required for this selection to be effective. The objective of this study was to evaluate the importance of homologous chromosome meiotic recombination in the creation of soybean cultivars. A set of 10 adapted high-yielding cultivars selected from the cross ‘Williams’ × ‘Essex’ was com-pared with a set of 156 random recombinant inbred lines (RILs) from the same population. Crossover events were identified using 143 simple sequence repeat (SSR) markers span-ning all 20 soybean …

Soybean has undergone several genetic bottlenecks. These include domestication in Asia to produce numerous Asian landraces, introduction of relatively few landraces to North America, and then selective breeding over the past 75 years. It is presumed that these three human-mediated events have reduced genetic diversity. We sequenced 111 fragments from 102 genes in four soybean populations representing the populations before and after genetic bottlenecks. We show that soybean has lost many rare sequence variants and has undergone numerous allele frequency changes throughout its history. Although soybean genetic diversity has been eroded by human selection after domestication, it is notable that …

Department of Agronomy and Horticulture: Faculty Publications
In previous works, it has been shown, by using ethylene inhibitors and precursors, that ethylene could participate in the regulation of the enhanced ferric reductase activity of Fe-deficient Strategy I plants. However, it was not known whether ethylene regulates the ferric reductase gene expression or other aspects related to this activity. This paper is a study of the effects of ethylene inhibitors and precursors on the expression of the genes encoding the ferric reductases and iron transporters of Arabidopsis thaliana (FRO2 and IRT1) and Lycopersicon esculentum (= Solanum lycopersicum) (FRO1 and IRT1) plants. The effects …

We conducted surveys of thistle-feeding insects on Canada thistle [Cirsium arvense (L.) Scop.] during the 2000 and 2001 growing seasons at Lacreek National Wildlife Refuge (LNWR), South Dakota, and analyzed their impact on thistle seed production, germination, and viability. Insects included Canada thistle stem weevil [Hadroplontus litura, formerly Ceurtorhynchus lilura, (Coleoptera: Curculionidae)], introduced at LNWR as a biocontrol agent, plus two seed head parasites, the thistle head weevil [Rhinocyllus conicus (Coleoptera: Curculionidae)] and the seed head fly [Terellia ruficauda (Diptera: Tephritidae)]. Infestation by these insects caused no significant reduction in per-head seed yield, with means ranging from 82.5 seeds per …

Christmas Bird Counts For North Dakota 2004, Robert N. Randall
The Prairie Naturalist
Christmas Bird Counts were made in 21 areas in North Dakota again in the year 2004. During the year a new count site was established in Pembina County and registered with the Audubon Society but an actual count was not made in the area this year. The location of the all areas in which counts were actually made is shown in Fig. 1. A relatively mild fall season leading up to the count period left much more open water than normal. Weather conditions during the count period varied widely with some areas reporting temperatures in the 40's and 50's of, …
Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews
Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews
The Prairie Naturalist
Nine species of sphecid wasps nesting in sparsely vegetated sandy soils near Ogallala, Keith County, Nebraska were studied during June 2003. The first records of the nest and prey of Cerceris clypeata gnarina Banks and Tachysphex williamsi R. Bohart are presented. Two species of weevils, Baris striata Say and B. subsimilis Casey, were prey of C. clypeata gnarina, with 12 to 22 individuals stocked per cell. Because B. subsimilis is a biological control agent for thistle, this finding is a caution to researchers not to ignore the potential impact of predatory wasps on the community. The single nest of T …

Grazing Intensity Effects On Northern Plains Mixed-Grass Prairie, Wendi M. Rogers, Donald R. Kirby, Paul E. Nyren, Bob D. Patton, Edward S. Dekeyser
The Prairie Naturalist
We evaluated the effects of long-term (1988 to 2000) grazing on northern mixed-grass prairie at tI.e Central Grasslands Research Extension Center in south-central North Dakota. We did not detect a difference in herbaceous basal cover between grazing intensities following 12 consecutive years of season-long moderate (50% removal of annual above-ground standing crop) and heavy (80% removal of annual above-ground standing crop) grazing. However, both moderate and heavy grazing intensities reduced above-ground herbaceous standing crop, total root biomass, and soil organic carbon. Moderate grazing intensity maintained a greater amount of deep (10 to 20 cm) and total root biomass relative to …
