A Place Called Pahaku, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

A Place Called Pahaku, Paul A. Johnsgard

Papers in Ornithology

There is an area in eastern Nebraska where the Platte River, after flowing northeastwardly from the vicinity of Kearney for nearly 150 miles, enters the glacial drift bordering the Missouri Valley and turns directly east. Over its eastward course of about 50 miles, the river forms a shallow and wide sandy channel that is bounded to the south by forested bluffs and to the north by a wide wooded floodplain. One of these glacially shaped and loess-capped bluffs was known historically to the resident Pawnee tribe as Pahaku (usually but incorrectly spelled as Pahuk) Hill. This Pawnee word may be ...

Evaluating Microfossil Content Of Dental Calculus From Brazilian Sambaquis, Verônica Wesolowski, Sheila Maria Ferraz Mendonça de Souza, Karl Reinhard, Gregório Ceccantini 2010 Escola Nacional de Saúde Pública Sérgio Arouca/Fiocruz

Evaluating Microfossil Content Of Dental Calculus From Brazilian Sambaquis, Verônica Wesolowski, Sheila Maria Ferraz Mendonça De Souza, Karl Reinhard, Gregório Ceccantini

Karl Reinhard Papers/Publications

To date, limited numbers of dental calculus samples have been analyzed by researchers in diverse parts of the world. The combined analyses of these have provided some general guidelines for the analysis of calculus that is non-destructive to archaeological teeth. There is still a need for a quantitative study of large numbers of calculus samples to establish protocols, assess the level of contamination, evaluate the quantity of microfossils in dental calculus, and to compare analysis results with the literature concerning the biology of calculus formation. We analyzed dental calculus from 53 teeth from four Brazilian sambaquis. Sambaquis are the shellmounds ...

A Functional Calcium-Transporting Atpase Encoded By Chlorella Viruses, Maria Cristina Bonza, Holger Martin, Ming Kang, Gentry L. Lewis, Timo Greiner, Sonia Giacometti, James L. Van Etten, Maria Ida de Michelis, Gerhard Thiel, Anna Moroni 2010 Università degli Studi di Milano

A Functional Calcium-Transporting Atpase Encoded By Chlorella Viruses, Maria Cristina Bonza, Holger Martin, Ming Kang, Gentry L. Lewis, Timo Greiner, Sonia Giacometti, James L. Van Etten, Maria Ida De Michelis, Gerhard Thiel, Anna Moroni

James Van Etten Publications

Calcium-transporting ATPases (Ca2+ pumps) are major players in maintaining calcium homeostasis in the cell and have been detected in all cellular organisms. Here, we report the identification of two putative Ca2+ pumps, M535L and C785L, encoded by chlorella viruses MT325 and AR158, respectively, and the functional characterization of M535L. Phylogenetic and sequence analyses place the viral proteins in group IIB of P-type ATPases even though they lack a typical feature of this class, a calmodulin-binding domain. A Ca2+ pump gene is present in 45 of 47 viruses tested and is transcribed during virus infection. Complementation analysis of ...

An Unfortunate Name—With A Nebraska Twist, Rick Wright 2010 WINGS Birding Tours Worldwide

An Unfortunate Name—With A Nebraska Twist, Rick Wright

Nebraska Bird Review

The past days have seen an amusing conversation about bird names conducted on the online discussion group NEBirds—just the sort of thing to get us through these dog-day afternoons of August. The scientific name of the Paltry Tyrannulet, a tropical flycatcher, is Zimmerius vilissimus, the genus so named by Melvin Traylor after American ornithologist John Todd Zimmer, who had a Nebraska connection through the university and State Museum in Lincoln. Combining the bird’s specific epithet from 1859—long preceding the new genus name of 1977—resulted in an English meaning of the entirety as “the very contemptible Zimmer ...


English And Scientific Alpha Code For The Birds Of Nebraska, Mark A. Brogie 2010 Nebraska Ornithologists' Union

English And Scientific Alpha Code For The Birds Of Nebraska, Mark A. Brogie

Nebraska Bird Review

Alpha codes, abbreviations of common or scientific bird names, have long been used by ornithologists. The U.S. Bird Banding Laboratory's employment of alpha codes has become an integral part of large ornithological programs across the United States and Canada. Rather than using the full English or scientific name of a bird species, alpha codes allow quicker data entry and can also help to cross-reference other data.

The content of this article is a list of alpha codes, current through the American Ornithologists' Union Checklist of North American Birds, Seventh Edition (1998), its following supplements (AOU: 2000, 2002, 2003 ...


Spring Field Report, March 2010 To May 2010, W. Ross Silcock 2010 Nebraska Ornithologists' Union

Spring Field Report, March 2010 To May 2010, W. Ross Silcock

Nebraska Bird Review

There was much of interest this spring. Early and late dates, early breeding, even a few rarities, are scattered through the species accounts. A few highlights are mentioned here. Mark Brogie found 6 species of Gallinaceous birds in one hour in Knox Co—quite a feat. Glossy Ibis reports continue to increase, and Mississippi Kites were found in new areas. Cranes made news: a leucistic Sandhill, another Common, and good numbers of Whoopings. Piping Plovers may be spreading out a bit, given the disappearance of the expanses of sand at L McConaughy, and amazing finds are being made by the ...

Annual Meeting At Chadron, 2010 University of Nebraska - Lincoln

Annual Meeting At Chadron

Nebraska Bird Review

Sixty-seven members and guests were in attendance at the 111th Annual Meeting of the Nebraska Ornithologists' Union held at Camp Norwesca on May 14–16, 2010. The Camp Norwesca campus, located just south of Chadron State Park, proved to be an excellent birding location, providing good views of Evening Grosbeaks and Red Crossbills. Evening Grosbeaks were also found at Chadron State Park and at Beaver Wall in Sheridan Co.

Field trips were led by Wayne Mollhoff, Kathy DeLara, Ann Duey, Alice Kenitz, and Bruce and Donna Walgren. Rain on Saturday morning caused some last-minute changes to the trip itineraries. Among ...

Farmer, Agent, And Specialist Perspectives On Preferences For Learning Among Today's Farmers, Nancy K. Franz, Fred Piercy, Joseph Donaldson, Johnnie Westbrook, Robert Richard 2010 Iowa State University

Farmer, Agent, And Specialist Perspectives On Preferences For Learning Among Today's Farmers, Nancy K. Franz, Fred Piercy, Joseph Donaldson, Johnnie Westbrook, Robert Richard

Extension and Outreach Research and Scholarship

Few studies have examined the types of educational delivery methods preferred by farmers (Eckert & Bell, 2005; Eckert & Bell, 2006). The research project reported here explored the preferred learning methods of farmers in Louisiana, Tennessee, and Virginia. Data on learning methods collected directly from farmers were compared with preferred teaching methods of Extension agents and specialists. The findings should shape agent and specialist perspectives on appropriate educational delivery methods when educating farmers and working towards farmer adoption of new practices.


Twin-Screw Extrusion Processing Of Distillers Dried Grains With Solubles (Ddgs)-Based Yellow Perch (Perca Flavescens) Feeds, Ferouz Y. Ayadi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Michael L. Brown 2010 South Dakota State University

Twin-Screw Extrusion Processing Of Distillers Dried Grains With Solubles (Ddgs)-Based Yellow Perch (Perca Flavescens) Feeds, Ferouz Y. Ayadi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Michael L. Brown

Kurt A. Rosentrater

Due to tremendous increases in global aquaculture production, compounded with limited availabilities of fish meal for fish feed, the need for alternative protein sources cannot be disregarded. Toward that end, twin-screw extrusion studies were performed to investigate the production of nutritionally-balanced feeds for juvenile yellow perch (Perca flavescens). Five isocaloric (~ 3.06 kcal/g) ingredient blends, adjusted to a similar protein content of 36.7% db, were formulated with 0, 10, 20, 30, and 40% distillers dried grains with solubles (DDGS) at an initial moisture content of 5-7% db, with appropriate amounts of fish meal, fish oil, whole wheat flour ...

Impacts Of Individual Tree Species On Carbon Dynamics In A Moist Tropical Forest Environment, Ann E. Russell, James W. Raich, Ricardo Bedoya Arrieta, Oscar Valverde-Barrantes, Eugenio González 2010 Iowa State University

Impacts Of Individual Tree Species On Carbon Dynamics In A Moist Tropical Forest Environment, Ann E. Russell, James W. Raich, Ricardo Bedoya Arrieta, Oscar Valverde-Barrantes, Eugenio González

Natural Resource Ecology and Management Publications

In the moist tropical forest biome, which cycles carbon (C) rapidly and stores huge amounts of C, the impacts of individual species on C balances are not well known. In one of the earliest replicated experimental sites for investigating growth of native tropical trees, we examined traits of tree species in relation to their effects on forest C balances, mechanisms of influence, and consequences for C sequestration. The monodominant stands, established in abandoned pasture in 1988 at La Selva Biological Station, Costa Rica, contained five species in a complete randomized block design. Native species were: Hieronyma alchorneoides, Pentaclethra macroloba, Virola ...


Design, Planning, And Evaluation Of Upgraded Cattle Handling Facility, Lindsey Kaeli Tulloch 2010 California Polytechnic State University - San Luis Obispo

Design, Planning, And Evaluation Of Upgraded Cattle Handling Facility, Lindsey Kaeli Tulloch

BioResource and Agricultural Engineering

This senior project discusses the design, planning, and evaluation of a livestock handling facility for Tulloch Ranches. The facility will be an upgrade to the facility currently used at the ranch in Pine Valley, California. The design parameters for the facility were narrowed down to the following: 1. Must reduce stress to animals during handling. 2. Must be cost effective to save labor and maintenance. 3. Must show improvement from the current set- up. The above parameters combine to form a system that enables the handlers of Tulloch Ranches to manage and work cattle in a more calm and humane ...


The Evolution Of Seeds, Ada Linkies, Kai Graeber, Charles A. Knight, Gerhard Leubner-Metzger 2010 Universitat Freiburg - UB Freiburg

The Evolution Of Seeds, Ada Linkies, Kai Graeber, Charles A. Knight, Gerhard Leubner-Metzger

Biological Sciences

The evolution of the seed represents a remarkable life-history transition for photosynthetic organisms. Here, we review the recent literature and historical understanding of how and why seeds evolved. Answering the 'how' question involves a detailed understanding of the developmental morphology and anatomy of seeds, as well as the genetic programs that determine seed size. We complement this with a special emphasis on the evolution of dormancy, the characteristic of seeds that allows for long 'distance' time travel. Answering the 'why' question involves proposed hypotheses of how natural selection has operated to favor the seed life-history phenomenon. The recent flurry of ...
