The Yosemite Butterflies (Text), And The Yosemite Butterflies (Text): Supplement Of Additional Information, Collections And Corrections For Volume 5, No. 1, Kenneth E. Davenport
The Taxonomic Report of the International Lepidoptera Survey
The current checklist covers the 170 known species and additional 48 subspecies known to occur in the Yosemite region, California, United States. This represents a total of 218 taxa (some being undescribed and unnamed) now recognized in the study area. This compares with Garth and Tilden’s 1963 survey which recognized 134 species and 16 additional subspecies, a total of 150 taxa. In addition to those, six additional species reported from the region are “questionable or doubtful” and another six species occur just outside the defined region.
The supplement includes additional information for the benefit of those who obtained the first …

Expression Of The Tobacco Β- 1,3-Glucanase Gene, Pr-2d, Following Induction Of Sar With Peronospora Tabacina, Deanna L. Funnell, Christopher B. Lawrence, Jeffrey F. Pedersen, Christopher L. Schardl
Department of Plant Pathology: Faculty Publications
Systemic acquired resistance (SAR) is induced following inoculation of Peronospora tabacina sporangia into the stems of Nicotiana tabacum plants highly susceptible to the pathogen. Previous results have shown that accumulation of acidic P-1,3-glucanases (PR-2's) following induction of SAR by P. tabacina may contribute to resistance to P. tabacina. We showed that up-regulation of the PR-2 gene, PR-2d, following stem inoculation with P. tabacina, is associated with SAR. Studies using plants transformed with GUS constructs containing the full length promoter from PR-2d or promoter deletions, provided evidence that a previously characterized regulatory element that is involved in response to …

Atrazine Runoff In The Blue River Basin: Geomorphology, Rainfall, And Agronomic Practices, Kundan Dhakal
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Atrazine concentrations in the Big Blue River Basin (BRB) in Nebraska and Kansas periodically exceed the U.S. EPA Maximum Contaminant Level (MCL) of 3 µg L-1. The present study is focused on watershed variables influencing surface runoff of atrazine. The assessment includes the impact of corn and sorghum planting progress (indicating atrazine application), rainfall, antecedent soil water content, and soil restrictive layer on stream-measured weekly atrazine load in independent BRB subwatersheds for 1997 - 2004. Maximum atrazine loading occurred after most of the corn had been planted but during sorghum planting from mid-May to early June, immediately following …

A survey of abomasal parasites in cervids from Central Spain was conducted at three sites, Quintos de Mora (Toledo), Maluéñez de Arriba (Cáceres), and La Herguijuela (Cáceres). Commonly occurring helminths belonged to three polymorphic species of the Ostertagiinae: Spiculopteragia asymmetrica/S. quadrispiculata, Ostertagia leptospicularis/O. kolchida, and O. drozdzi/O. ryjikovi. Trichostrongylus axei was found in very few cases. Ostertagia drozdzi/O. ryjikovi and the minor male morphotype, S. quadrispiculata, are reported for the first time in red deer from Spain. The three ostertagiine species are also reported for the first time …

Military training can often be destructive to the environment. Environmental impacts associated with heavy training include soil compaction, soil erosion, siltation of waterways and wetlands, increased threat of flooding, loss of wildlife habitat, declining biodiversity, and invasion by noxious weeds. Planning and implementing land rehabilitation projects generally involves some soil movement, establishment of vegetation, stabilization and hardening of sites, etc. Procurement of appropriate heavy equipment and other specialized equipment is sometimes a difficult task that involves obtaining multiple vendors, especially when procuring equipment for rental, lease, or purchase. This report and associated database were created to help land managers easily …

Does Birding Have A Future?, Rick Wright
Does Birding Have A Future?, Rick Wright
Nebraska Bird Review
Does birding have a future?
Now this might seem an odd question, even an absurd question, to pose to an audience like this, and the answer might seem obvious. How could birding not have a future when we, all of us, are birders who bird, and when survey after recent survey assures us that our numbers are growing, our diversity increasing, and our economic and ethical contributions to American society ever more conspicuous. Does birding have a future? The simple answer is yes.
That's the simple answer. The more interesting answer is yes-yes, but. Yes, birding has a future, but …

EBV transforms primary B cells, and the major EBV oncoprotein, latent membrane protein 1 (LMP-1), is required for the process. LMP-1 both induces the expression of IRF-7 and activates the IRF-7 protein by phosphorylation and nuclear translocation. Here we report that the expression of IRF-7 is increased in EBV-immortalized B lymphocytes compared with that in primary B cells. IRF-7 was phosphorylated and predominantly localized in the nucleus in the immortalized cells. The expression of IRF-7 was detected in 19 of 27 specimens of primary lymphomas of the human central nervous system by immunohistochemical analysis. The association between LMP-1 and IRF-7 …

Nebraska Bird Review
In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry conditions surely …

Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton
Nebraska Bird Review
Since 1992 the Central Nebraska Public Power and Irrigation District (Central) has protected and monitored nesting Piping Plovers along the shore of Lake McConaughy (Keith County, Nebraska). Over those 13 seasons, Central monitored 849 Piping Plover nests and documented the successful fledging (successful fledging is defined as a chick at least 24 days old, or one observed flying) of 1,237 Piping Plover chicks (Table 1), making Lake McConaughy one of the most productive nesting areas for Piping Plovers in Nebraska. The following is a documentation of the contributions of Lake McConaughy to the recovery goals for Piping Plovers in Nebraska. …

Fall Field Report, August-November 2004, W. Ross Silcock
Nebraska Bird Review
The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.
Counts of interest were 3000 Double-crested …

Buffalograss Germplasm Resistance To Blissus Occiduus (Hemiptera: Lygaeidae), Osman Gulsen, Tiffany Heng-Moss, Robert C. Shearman, P. Stephen Baenziger, Donald J. Lee, Frederick P. Baxendale
Department of Entomology: Faculty Publications
Plant germplasm collections may offer genetic variability useful in identifying insect resistance. The goal of this project was to evaluate buffalograss genotypes [Buchloe dactyloides (Nutt.) Engelm.] for resistance to the chinch bug, Blissus occiduus Barber (Hemiptera: Lygaeidae), and to relate resistance to ploidy level, chinch bug number, and pubescence. Forty-eight buffalograss genotypes from diverse geographic locations were evaluated in replicated studies under greenhouse conditions. Of the genotypes studied, four were highly resistant, 22 were moderately resistant, 19 were moderately susceptible, and three were highly susceptible to chinch bug damage. The mean number of chinch bugs was significantly different among …

Military training often results in environmental degradation that has negative impacts on future training missions. The U.S. Army Construction Engineering Research Laboratory (CERL) conceptualized the Army’s Integrated Training Area Management (ITAM) program in response to the concerns expressed by military land managers and trainers over the declining condition of training and testing lands. ITAM has evolved to include land condition and trend analysis (LCTA), environmental awareness (EA), training requirements integration (TRI), and land rehabilitation and maintenance (LRAM). The need for LRAM has increased dramatically over the past decade. Among the many difficulties faced in planning and implementing a land rehabilitation …

Agronomic Responses Of Corn Hybrids From Different Eras To Deficit And Adequate Levels Of Water And Nitrogen, Patrick M. O'Neill, J.F. Shanahan, James S. Schepers, Bob Caldwell
Department of Agronomy and Horticulture: Faculty Publications
Maintaining current high yields of corn (Zea mays L.) grown in the USA poses an environmental threat due to continued overuse of water and N inputs. To reduce overreliance on inputs, future corn breeding efforts should focus on improving tolerance of corn to water and N stresses, utilizing appropriate tolerance mechanisms. The objective of this study was to identify appropriate mechanisms by characterizing agronomic responses of 12 hybrids from three different eras (‘B73 x Mo17’ from 1970s and three early 1990s and eight late 1990s Pioneer brand hybrids) to varying water and N supply. This was done by growing …

Seventy-one 10th-generation gilts from White Line-1 (WL-1 = randomly selected control line) and White Line-2 (WL-2 = selected for an index of ovulation rate and prenatal survival rate) were used to compare the pattern of follicular development and atresia during the follicular phase of the estrous cycle. Gilts were treated with PGF2α on d 13 of the estrous cycle (d 0 of induced follicular development) to induce luteolysis and assigned randomly within line and sire for ovary recovery on d 0, 2, 3, 4, 5, and the day after estrus. Ovaries were evaluated for numbers of corpora albicantia and …
