Endangered And Threatened Wildlife And Plants; Determination Of Endangered Status For The Pallid Sturgeon

Endangered Species Bulletin

The Service determines the pallid sturgeon (Scaphirhynchus albus) to be an endangered species under authority of the Endangered Species Act (Act) of 1973. Critical habitat is not being designated. The pallid sturgeon is a large fish known only to occur in the Missouri River, the Mississippi River downstream of the Missouri River, and the lower Yellowstone River. The species is threatened through habitat modification, apparent lack of natural reproduction, commercial harvest, and hybridization in parts of its range. This rule identifies the taxon as one in need of conservation, implements protective measures, and makes available recovery measures provided …

Soybean Chlorosis Studies On High Ph Bottomland Soils, E. J. Penas, R. A. Wiese, R. W. Elmore, G. W. Hergert, R. S. Moomaw

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Soybean varieties are different in tolerance to lime-induced chlorosis. Field trials were conducted to evaluate variety performance on soils where chlorosis in soybeans was a known problem. Thirty-six varieties out of 177 were identified as tolerant to soil conditions that cause chlorosis. Eleven varieties of these 36 were found to have the most consistent yield performance on high pH soils. Tolerant varieties must be planted at adequate densities for best performance. A seeding rate of 13.5 seeds per foot of row, the highest seeding rate employed, did not appear to maximize yield on soils where chlorosis was severe. On some …

Sex Reversal Of Tilapia In Earthen Ponds, Tom Popma, Bartholomew Green

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

This Aquacultural Production Manual from the International Center for Aquaculture at Auburn University is oriented towards field application rather than rigorous scientific evaluation of the described techniques. The management practices have been field tested and proven feasible at the described scale of production.

The intended readers are intermediate to upper level technicians with experience in related aquacultural activities. As such, a basic understanding of the principles of aquatic production and of the life history and environmental requirements of tilapia is presumed.

Ermelo Weeping Lovegrass Response To Clipping, Fertilization, And Watering, Robert A. Masters, Carlton Britton

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

A management strategy using short-duration grazing and fertilization was simulated in a study with individual 'Ermelo' weeping lovegrass [Eragrostis curvula (Shrad.)Nees] plants. Influence of 2 levels of clipping [unclipped during the growing season and clipped (C) to 10-cm stubble height each time regrowth reached 40 cm]; fertilizer [unfertilized and 70-34-44 kg N-P-K/ha (F)]; and watering frequency [irrigated to field capacity at 7- (WET) and 14- (DRY) day intervals] on cumulative herbage dry matter yield, crude protein yield, and water-use efficiency, and root mass of individual weeping lovegrass plants grown in soil contained in polyethylene tubes was determined. Clipping combined …

Nebraska Bird Review

FIRST NEBRASKA KITTIWAKE SPECIMEN

The Black-legged Kittiwake (Rissa tridactyla) has previously been known from Nebraska only from a few sight records. Dr. George Hudson observed one at Oak Creek Park, Lincoln, in March, 1939 (NBR 5:57). Another individual was seen at Branched Oak Lake, Lancaster County, during April of 1976. Thirdly, an immature was seen and photographed at Oak LakePark, Lincoln, on April 20-21, 1981 (NBR 49:41). Lastly, during the fall occurrence report for 1988 (NBR 57: 16, 53) Kittiwakes were reported from Cedar and Douglas-northern Sarpy counties, the Cedar County sightings involving up to …

Indigo Bunting

Nebraska Bird Review

INDIGO BUNTING John Lueshen reported that a male Indigo Bunting was found dead in the front yard of his place (Route 2, Wisner - Ed.) It had band number 81-44804, put on by Willetta Lueshen on July 2, 1985. It was at least a year old when banded, making it at least six years old. Another male Indigo Bunting was attacking the dead bird when John first saw it.

More On The Whistling Duck Article

Nebraska Bird Review

MORE ON THE WHISTLING DUCK ARTICLE In the report on the Whistling-Duck, Mr. Labedz mentioned a sighting in Minnesota (NBR 58:51.) He now adds that a more recent issue of The Loon (62: 109) reports this was an escapee. Some skeptics noted that the site was near a game farm and called the farm. The farm owner reported that the bird escaped while its pen was being constructed, but was recaptured a couple of days later. There are approximately 1,100 game farms in Minnesota.

Warm-Season Grass Establishment As Affected By Post-Planting Atrazine Application, C. C. Bahler, Lowell E. Moser, T. Griffin, Kenneth P. Vogel

Department of Agronomy and Horticulture: Faculty Publications

Atrazine [6-chloro-N-ethyl-N’-methylethyl)-1,3,5-triazine-2,4-diamine] provides effective weed control during big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatrum L.) establishment. However, most other desirable warm-season grasses are susceptible to atrazine injury at establishment. The objective of this study was to determine if atrazine applications after seedling would affect susceptible warm-season grass establishment. Big bluestem, switchgrass, Indiangrass [Sorghastrum nutans (L.) Nash], sideoats grama [Bouteloua curtipendula (Michx.) Torr.], and little bluestem [Schizachyrium scoparium (Michx.) Nash] were needed into greenhouse flats or field plots and 2.2 kg a.i. atrazine/ha applied at 0 (atrazine control), 7, 14, or 21 days after …

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Life History Differences Between Two Species Of Gregarina In Tenebrio Molitor Larva, Tim R. Ruhnke, John J. Janovy Jr.

John Janovy Publications

The life histories of two species of Gregarina, protozoans parasitizing Tenebrio molitor, were compared. Gregarina cuneata occurred primarily in larger larvae, whereas Gregarina steini was distributed evenly throughout all sizes of larvae. As larval size increased, an increase in prevalence of G. cuneata preceded a more substantial increase in parasite relative density. Sample variance/relative density ratios of the two parasite species also differed. When host larvae were isolated in a sterile bran medium, the prevalence of G. cuneata decreased, whereas that of G. steini remained relatively high. Trophozoites of G. cuneata were found predominantly in a paired condition, …

Cysticerci (Cestoda: Taeniidae) From White-Tailed Deer, Odocoileus Virginianus, In Southern Florida [Research Notes], Donald J. Forrester, Robert L. Rausch

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

Metacestodes (cysticerci) of Taenia omissa Liihe, 1910, and Taenia hydatigena Pallas, 1776, were found in 9 and one of 124 white-tailed deer, respectively, in southern Florida in 1984-1986. Intensities of T. omissa varied from 1 to 15 (x[bar] = 4.6); only one cysticercus of T. hydatigena was collected. No significant difference in the prevalences of T. omissa according to sex, age, or locality was observed.
