Endemicity And Regional Biodiversity In Nebraska's Breeding Avifauna, Paul A. Johnsgard

Papers in Ornithology

I estimate that 215 bird species currently breed or have previously bred in Nebraska. This number compares with a total of 330 spe¬cies that breed or have bred in the Great Plains region south of Canada, as I defined that region in my book on the breeding birds of the Great Plains (Johnsgard, 1979). An analysis of the relative species diversity of Nebraska's breeding avifauna establishes several areas of unusual species richness and endemicity, these most important being the Missouri Valley and associated middle to lower Niobrara Valley, the Pine Ridge area of the northwestern Panhandle, and the entire Platte …

Ecological Effects Of Major Storms On Coastal Watersheds And Coastal Waters: Hurricane Bob On Cape Cod, I. Valiela, P. Peckol, C. D'Avanzo, J. Kremer, D. Hersh, K. Foreman, K. Lajtha, B. Seely, W. R. Geyer, T. Isaji, R. Crawford

Biological Sciences: Faculty Publications

Hurricane Bob, a category 3 storm, made landfall on Cape Cod in August 1991, and its effects on watersheds and adjoining estuaries were detected in the ongoing studies being caried out as part of the Waquoit Bay Land Margin Ecosystems Research project. On land, Bob had only minor overall effects on forests; localized wind bursts did snap and break trees in small and widely scattered forest parcels. Wind stripped up to half the leaves of deciduous trees and many herbaceous plants on the watershed, and most remaining leaves were damaged by salt, so that by the end of Aug, Cape …

Parasitism Of Greenbugs (Homoptera: Aphididae) By Lysiphlebus Testaceipes (Hymenoptera: Braconidae) In Grain Sorghum: Implications For Augmentative Biological Control, Odair A. Fernandes, Robert J. Wright, Z. B. Mayo

Department of Entomology: Faculty Publications

Field cage studies were conducted to describe the relationship between the percentage of Lysiphlebus testaceipes (Cresson) parasitism (as measured by aphid mummies) and densities of greenbug, Schizaphis graminum Rondani, on grain sorghum, Sorghum bicolor L. In 1993 and 1994, a biotype E-susceptible grain sorghum hybrid was grown in field cages and L. testaceipes adults were released after each plant was infested with 20 biotype E greenbugs. The release rates were 0, 0.5, 1.0, and 2.0 wasps per plant in 1993, and 0, 0.16, 0.33, and 0.5 wasps per plant in 1994. Greenbugs and mummies were counted 1-2 times a week …

Identification And Characterization Of Spcu, A Chaperone Required For Efficient Secretion Of The Exou Cytotoxin, Viviane Finck-Barbançon, Timothy L. Yahr, Dara W. Frank

Dartmouth Scholarship

In recent studies, we have shown that Pseudomonas aeruginosa strains that are acutely cytotoxic in vitro damage the lung epithelium in vivo. Genetic analysis indicated that the factor responsible for acute cytotoxicity was controlled by ExsA and therefore was part of the exoenzyme S regulon. The specific virulence determinant responsible for epithelial damage in vivo and cytotoxicity in vitro was subsequently mapped to the exoU locus. The present studies are focused on a genetic characterization of the exoU locus. Northern blot analyses and complementation experiments indicated that a region downstream of exoU was expressed and that the expression of this …

A New Eimeria Species (Apicomplexa: Eimeriidae) Infecting Onychomys Species (Rodentia: Muridae) In New Mexico And Arizona, John A. Hnida, Wade D. Wilson, Donald W. Duszynski

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

Fecal samples from 3 species of Onychomys (Rodentia: Muridae) captured in New Mexico and Arizona were examined for coccidia. Six of the 59 (10%) were infected with a new species of Eimeria. Sporulated oocysts (n = 105) of this new species are subspheroidal, 17.4 × 16.1 (14-21 × 13-19) μm, with ellipsoidal sporocysts 10.4 × 5.7 (9-12 × 5-8) μm. This species occurred in 3 of 24 (13%) Onychomys arenicola, 2 of 31 (6%) Onychomys leucogaster from New Mexico, and 1 of 4 (25%) Onychomys torridus from Arizona. Isolates recovered from O. leucogaster and O. torridus were …

Observations On Groundwater Recharge In The Westdale Catchment, M F. Lewis, C E. Mcconnell

Resource management technical reports

A study of the role of groundwater carriers and barriers in controlling salinity was carried out in the Westdale Catchment by Lewis and McConnell (in preparation). Although that study was primarily concerned with groundwater flow and discharge processes, the data collected also provided rudimentary information on the timing of groundwater recharge events and their distribution across the landscape.

Bird Banding Notes From Ruth Green, Ruth Green

Nebraska Bird Review

On 29 April 1998, while working with school children from the Chadron Public Schools, Ruth banded a Pine Siskin at Nebraska's Chadron State Park, Dawes County. Approximately seven and a half months later, on 12 December, this same bird was recovered beneath a feeder in Springfield, Oregon. The Pine Siskin was dead, perhaps a victim of disease sweeping the siskin population on the West Coast. This particular occurrence is noteworthy for the distance traveled both west and north.

The Summer Tanager pictured below was also banded by Betty. She banded the AHY-F (After Hatching Year, Female) Summer Tanager on 10 …

1997 (9th) Report Of The Nou Records Committee, Mark A. Brogie

Parasitic Jaeger At Lake Mcconaughy, Stephen J. Dinsmore, W. Ross Silcock

Nebraska Bird Review

On 5 October, 1997, we joined Joel G. Jorgensen and John Sullivan for a pelagic trip on Lake McConaughy. A similar trip in late September 1996 yielded a Sabine's Gull, but we were really hoping to see a jaeger. From 7:00 to 8:30 a.m. we gradually worked our way from the dam towards the western end of the lake. Besides moderate numbers of Franklin's and Ring-billed Gulls, there were few birds on the lake. At approximately 8:45 a.m. Dinsmore noticed that all of the gulls at the western end of the lake had suddenly taken flight. Less than a minute …

Fall Field Report, August To November 1998, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Larry Einemann kindly pointed out that in the Spring Report all his sightings from Pioneer's Park should have been attributed to Wilderness Park at Pioneer's Boulevard (in Lincoln). Larry noted that Pioneer's Park is a manicured Lincoln city park which is not good for birds except for in the vicinity of the embedded Chet Ager Nature Center. This was my (WRS) error; personally I have trouble even finding the Wilderness Park entrances, let alone naming them properly!

Another correction! John Sullivan pointed out that the 2 Summer Tanagers at Indian Cave SP on 10 August, 1997, were not his sighting. …

Management Of The Houtman Abrolhos System., Kim Nardi, Abrolhos Islands Management Advisory Committee

Fisheries management papers

The Abrolhos System is the Houtman Abrolhos Islands and adjoing State Territorial Waters. It is an important part of the Western Australian environment. Has major significance in conservation of flora and fauna and also in geological terms. The waters adjoining State Territorial Waters contain some of the most highly valued marine systems in the State. These include sites of historical shipwrecks in Australia. The are of great interest to visitors and support a relatively small but growing recreation and tourism industy.

The area is integral to the Western rock lobster fishery, which is that State's premier primary industries. The Abrolhos …

Regeneration Of Hair Cell Epithelia In The Chick And Salamander, Kenneth Detwiler

Masters Theses & Specialist Projects

The acousticolateralis sensory system is characterized by a specific receptor cell type called the sensory hair cell and is found in all vertebrates. There are two types of hair cell sensory epithelia based on location: those of the inner ear, such as the organs for hearing and balance, and the lateral line system located within the epidermis. In mammals, including humans, loss or damage of the hair cells of the auditorysystem results in permanent hearing loss. However, this is not the case with birds and amphibians. Amphibians, with a lateral line system, are capable of replacing lost or damaged hair …

Selenocysteine-Containing Proteins In Mammals, Vadim N. Gladyshev, Dolph L. Hatfield

Vadim Gladyshev Publications

Since the recent discovery of selenocysteine as the 21st amino acid in protein, the field of selenium biology has rapidly expanded. Twelve mammalian selenoproteins have been characterized to date and each contains selenocysteine that is incorporated in response to specific UGA code words. These selenoproteins have different cellular functions, but in those selenoproteins for which the function is known, selenocysteine is located at the active center. The presence of selenocysteine at critical sites in naturally occurring selenoproteins provides an explanation for the important role of selenium in human health and development. This review describes known mammalian selenoproteins and discusses recent …

Photosynthetic Parameters And Empirical Modeling Of Primary Production: A Case Study On The Antarctic Peninsula Shelf, Mark A. Moline, Oscar Schofield, Nicolas P. Boucher

Biological Sciences

Eight hundred photosynthesis-irradiance relationships were determined in the shelf waters adjacent to Palmer Station, Antarctica during the spring/summer periods of 1991–94. Biomass specific maximum photosynthetic rate, P^B_max, and the light limited photosynthetic efficiency, α^B, were poorly correlated to the physical forcing and nutrient regimes at the sampling stations. The two photosynthetic parameters, however, did strongly covary indicating the minimum irradiance required to saturate photosynthesis, I^k, was relatively constant in this highly variable environment. The variability in I^k could partially be attributed to both depth in the water column and time of the …

Scales 2: Computer Program To Convert Among Developmental Stage Scales For Corn And Small Grains, Dorothy M. Harrell, Wallace Wilhelm, Gregory S. Mcmaster

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

Producers and agronomists need crop developmental scales that are easy to use, universally accepted, and accurate. Development of such a scale requires correlation of stages among scales currently in use and correlation of developmental patterns among crops. A computer program for converting among staging systems is a useful tool in developing new staging systems with wider applicability. The BBCH scale (BASF-Bayer-Ciba-Geigy-Hoechst) has been proposed as a prototype of a universal scale. We have added the BBCH scale to our scale conversion program for wheat (Triticum aestivum L.) and developed a similar conversion program for corn (Zea mays L.), …

Structure Of The Protein Kinase Cβ Phospholipid-Binding C2 Domain Complexed With Ca2+, R. Bryan Sutton, Stephen R. Sprang

Biological Sciences Faculty Publications

Background: Conventional isoforms (α, β and γ) of protein kinase C (PKC) are synergistically activated by phosphatidylserine and Ca²⁺; both bind to C2 domains located within the PKC amino-terminal regulatory regions. C2 domains contain a bipartite or tripartite Ca²⁺-binding site formed by opposing loops at one end of the protein. Neither the structural basis for cooperativity between phosphatidylserine and Ca²⁺, nor the binding site for phosphatidylserine are known. Results: The structure of the C2 domain from PKCβ complexed with Ca²⁺ and o-phospho-L-serine has been determined to 2.7 Å resolution using X-ray crystallography. The …

Detection Of The Fast Kelvin Wave Teleconnection Due To El Niño‐Southern Oscillation, Steven D. Meyers, Arne Melsom, Gary T. Mitchum, James J. O'Brien

Marine Science Faculty Publications

Previous analyses of the ocean state along the western American coast have often indicated unexpectedly slow and limited propagation of coastally trapped Kelvin waves associated with the El Niño‐Southern Oscillation. In contrast, theoretical and numerical ocean models demonstrate that these Kelvin waves are a rapid and long‐range teleconnection between the low‐ and high‐latitude Pacific Ocean, strongly impacting both the surface coastal currents and nutrient upwelling. Sea level variations along the western coast of North America are reexamined under the assumption that tropically forced Kelvin waves are produced in bursts of several months duration. A cross‐correlation analysis, restricted to mid‐1982 to …

An Empirical Algorithm For Light Absorption By Ocean Water Based On Color, Zhongping Lee, Kendall L. Carder, R. G. Steward, T. G. Peacock, C. O. Davis, J. S. Patch

Marine Science Faculty Publications

Empirical algorithms for the total absorption coefficient and absorption coefficient by pigments for surface waters at 440 nm were developed by applying a quadratic formula that combines two spectral ratios of remote-sensing reflectance. For total absorption coefficients ranging from 0.02 to 2.0 m(-1), a goodness of fit was achieved between the measured and modeled data with a root-mean-square difference between the measured and modeled values for log10 scale (RMSDlog10) of 0.062 (15.3% for linear scale, number of samples N = 63), while RMSDlog10 is 0.111 (29.1% for linear scale, N = 126) for pigment absorption (ranging from 0.01 to 1.0 …

Ecosystem Metabolism In A Subtropical Seagrass-Dominated Lagoon, Susan Ziegler, Ronald Benner

Faculty Publications

Measurements of ecosystem gross primary production (GPP) and respiration (R) were made for 2 to 3 consecutive days on 10 occasions from February 1996 through June 1997 in the seagrass-dominated Laguna Madre (Texas, USA). Ecosystem GPP and R were quantified using 3 independent measurements including the open-water technique using dissolved oxygen (DO) and dissolved inorganic carbon (DIC) and the summation of discrete measurements of the water column and benthos. Diel curves of DIC were often influenced by water movement while the impact of water movement on DO was not apparent. This was attributed to the longer turnover time of DIC …
