Tillage And Fertilizer Influences On Corn And Legume Cover, J. E. Gilley, J. F. Power, P. J. Reznicek, S. C. Finkner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The use of legumes in a cropping system may provide a variety of benefits. In this study, the effectiveness of selected legume species in providing surface cover was examined. The legumes were interseeded into either conventional or no-till corn, with or without N fertilizer. Both maximum legume cover and maximum cover furnished by corn plus legumes were examined. Mean cover provided during the study period by both the cover crop, and corn plus cover crop was also determined.

1988 Fall Field Day

Nebraska Bird Review

Some innovations greeted the 60 registrants at the 1989 Field Day, 6 October, at the 4-H camp at Halsey National Forest: there was a canoe float down the Middle Loup River and a lesson on bird calls Saturday morning, in additl0 to the usual self-guided birding trips and demonstration of bird banding. Blow ups of the field card were posted, so that sightings could be posted currently and locations of special sightings could be written on a chalkboard. Saturday morning was overcast and chilly (otherwise the weather was sunny and mild), but 7 did make the float trip down to …

Have The Northern Cardinal And The Red-Bellied Woodpecker Expanded Their Ranges In Nebraska Recently, 1968-1987?, E.H. Maddux

Nebraska Bird Review

The Northern Cardinal (Cardinalis cardinalis) and the Red-bellied Woodpecker (Melanerpes carolinus) are both common permanent residents of Nebraska (Johnsgard 1980: Bray, Padelford, and Silcock i986). Over at least the last four decades there have been published reports that the two species have been expanding their respective ranges to the west and to the north. In the case of the Northern Cardinal the range expansion has been extensive in distance and has occurred over a long period of time. "Originally a bird of the south, the Kentucky Cardinal, or Virginia Redbird, has pushed its way northward until …

"Notes," From Nebraska Bird Review (December 1989) 57(4)

Nebraska Bird Review

MINK AND OTTER. On a trip to West Point on 2 June 1989 I took N 79 north to Snyder. As I was travelling north near the town of Prague I noticed a large river otter loping through a field in broad daylight, paralleling a a wooded stream. It probably was an itinerant, recently released, and was going about the business of looking for a better home. Later that day, near West Point, I saw a mink quickly cross the road from one stream to another, in the area of a wet prairie surrounding both sides of the road.' I …

My Association With William Steel Creighton, George C. Wheeler

Insecta Mundi

The recent (1986) publication of “My Association with William Morton Wheeler” evidently stirred my latent autobiographical urge. It is quite reasonable that I should next apply it to William Steel Creighton, for he certainly ranks next to W. M. Wheeler among American myrmecologists. It will be quite different, however, because my actual association with Creighton was very brief twice a dinner guest in New York City and two visits in La Feria, Texas. Correspondence, however, is quite different. I received 45 letters from W. M. Wheeler between 1919 and 1936; the last was dated four months before his death. They …

Recent Sedge Wren Observations In Nebraska, Mary Clausen

Nebraska Bird Review

The Sedge Wren (Cistothorus platensis) in Nebraska was considered by Rapp (1958) an uncommon migrant in the eastern third of the state, and a rare breeder in suitable marshes in the eastern quarter, and by Johnsgard (1986) as an uncommon spring and fall migrant in the east and a rare summer resident in the eastern third of the state, mostly east of a line from Knox to Gage counties. Recent articles have prompted questions concerning the rarity of Sedge Wrens nesting in Nebraska (Bedell 1987, Lingle and Bedell 1989) and the possibility that may be nesting late in …

Species Richness Gradients Of Oak Forest Plants Along The Missouri River In Nebraska And Iowa, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The upland deciduous forests of the Missouri River valley contain many plants typical of forests to the east of this area, which are assumed to have migrated northward and westward along the river in postglacial times. Previous workers have reported a gradient of decreasing species richness upstream among woody species, which is suggested to be the result of climatic gradients and differential dispersal capabilities of the immigrant species. Floristic work on all vascular species in eight woodland sites along the Nebraska-Iowa border quantifies the presence of similar gradients for herbaceous species, but of differing degrees. These studies also reveal the …

Revised Techniques For The Study Of Ant Larvae, George C. Wheeler, Jeanette Wheeler

Insecta Mundi

In 1960 we published "Techniques for the study of ant larvae." We referred to it in 1976 and again in 1986. In the intervening years three authors have cited it and the quality of their drawings suggest they have benefited from our suggestions. The poor quality of most other recent drawings suggest they have not seen our article. Perhaps a 1960 reference is too old to be caught in latter-day "literature searches." Or, if the searcher did find it, he was unwilling to take the trouble to follow the recommended techniques. And troublesome they are, especially if one does not …

Can Genetically Engineered Crops Become Weeds?, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

There are significant differences if the distribution of weedy characteristics among weeds, normal plants, and crops. The world’s most serious weeds possess on the average 10 or 11 of these characters, a random collection of British plants have an average seven of the traits, and crop plants only five. For the average crop to become as “weedy” as the average weed, it would need to acquire five weedy traits. Even using the unlikely assumption that those traits are single loci in which a dominant mutation would provide the weedy character, this would require the simultaneous acquisition of five gene substitutions. …

Soil Disturbance-Residue Management Effect On Winter Wheat Growth And Yield, Wallace Wilhelm, H. Bouzerzour, J. F. Power

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The need to reduce soil erosion, maximize soil water conservation, and optimize grain production in dryland cropping systems in the Central Great Plains has culminated in development of nontilled fallow systems. These systems have greatly reduced the degree of soil disturbance, and the amount and degree of residue incorporation. The objectives of this study were to evaluate the influence of soil disturbance and residue management on soil temperature, soil water, and winter wheat (Triticum aestivum L.) growth. Two field studies were established in 1981 and 1982 on an Alliance silt loam (Fine-silty, mixed, mesic Aridic Argiustoll) with treatments consisting …

An Alternative Approach For Evaluating The Efficacy Of Potential Biocontrol Agents Of Weeds. 2. Path Analysis, Dan J. Pantone, William A. Williams, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Path analysis was used to assess the efficacy of the fiddleneck flower gall nematode as a weed biocontrol agent of coast fiddleneck in competition with wheat during two years of field experiments. The path analysis revealed that the number of inflorescences/plant for fiddleneck and the number of heads/plant for wheat were the most important yield components that determine fecundity and seed yield. The density of fiddleneck had a much greater impact on the yield components of fiddleneck than did the density of wheat or the nematode rate of inoculation. The nematode had its greatest negative impact on the number of …

Index Selection For Components Of Litter Size In Swine: Response To Five Generations Of Selection, S. M. Neal, R. K. Johnson, R. J. Kittock

Department of Animal Science: Faculty Publications

Selection for an index of ovulation rate (OR) and embryo (fetal) survival rate (ES) to 50 d of gestation (I = 10.6 x OR + 72.6 x ES) was practiced for five generations in a line that was a composite population of the Large White and Landrace breeds of swine. A control line sampled from the same population was selected randomly and mated. Ovulation rate and number of fetuses (FETS) were measured by laparotomy and ES was calculated as FETS/OR. The select line averaged 43 litters by 18 sires and the control line averaged 42 litters by 15 sires per …

Control Of Luteinizing Hormone In Postpubertal Boars With Large Testes, P. L. Wolfe, M. W. Wolfe, T. T. Stumpf, J. A. Stotts, M. L. Day, R. J. Kittock, R. K. Johnson, J. E. Kinder

Department of Animal Science: Faculty Publications

The objective of the present study was to investigate endocrine control of LH in post-pubertal boars with large testes. Eight boars with the highest estimated paired testis weights from a line selected for large testes and nine boars from a line selected at random were used. Blood samples were collected over a 13-h period at weekly intervals for 4 wk. Samples were collected at 12-min intervals for 12 h before and 1 h after exogenous LHRH. Boars were bled when they were intact during the initial week. The second and third blood collections were 7 and 14 d after castration. …

A Revision Of The North American Papillose Allocreadiidae (Digenea) With Independent Cladistic Analyses Of Larval And Adult Forms, Janine N. Caira

Bulletin of the University of Nebraska State Museum

Adult specimens of all 19 North American species of papillose allocreadiids were examined. A description and figure is given for the adult of each species; details of the cirrus sacs are presented for most spesies for the first time. Descriptions were emended where necessary and judgments were made on synonymies. Scanning electron micrographs of the oral sucker of 10 species are presented as is a new key to the 19 species. A cladistic analysis was performed on the group based on adult characters. The analysis indicated that the group is monophyletic on the basis of the ventral papillae associated with …

The Water Vapor Conductance Of Squamate Reptilian Eggs: The Influence Of Scaling On Nesting Ecology., Louis A. Somma

Papers in Herpetology

Flexible-shelled eggs of squamate reptiles are strongly influenced by their surrounding microclimate, particularly the hydric conditions of the nest. The eggshell water vapor conductance of an egg can be an indication of its requirement for water from the nest. Ackerman et al. (1985. Physiol. Zool. 58:129-137) have described the scaling relationship for eggshell water vapor conductance (G_H2O) of flexible-shelled reptilian eggs (G_H2O = 981.8M^0.52). This scaling relationship was investigated with water vapor conductance data obtained from 8 species of lizards representing the families Iguanidae (Anolis carolinensis, A. sagrai, Sceloporus woodi, S. virgatus) …
