Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr. Jan 1987

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.

Journal of the Arkansas Academy of Science

The United States government established a trading house at Arkansas Post in 1805 on the north bank of the Arkansas River in the newly purchased Louisiana Territory. The goal of this trading house was to foster good relations with the Quapaw tribe and other indigenous peoples. John B. Treat and his successors operated the post and meticulously recorded the number, value, and species of pelts traded. Tabulation of these records, which have been preserved in the National Archives, revealed that 9 or 10 species contributed a total of about 44,000 hides, worth approximately $18,000. White-tailed deer (Odocoileus virginianus) pelts comprised …

The Identification Of The Threatened Southeastern Shrew Using Multivariate Statistical Techniques, Thomas M. Padgett, Roger K. Everton, Robert K. Rose Jan 1987

The Identification Of The Threatened Southeastern Shrew Using Multivariate Statistical Techniques, Thomas M. Padgett, Roger K. Everton, Robert K. Rose

Biological Sciences Faculty Publications

The threatened subspecies of the southeastern shrew, Sorex longirostris fisheri, is endemic to the Great Dismal Swamp of southeastern Virginia. Previous studies based on discriminant analysis of external measurements determined that intergrades with the upland form, Sorex l. longirostris, exist along the periphery of the Swamp. To better discriminate among these populations, a study of cranial morphology was initiated. Fifteen cranial measurements were taken, using 59 specimens of Sorex collected previously form southeastern Virginia, including the Dismal Swamp. Both Principal Component and Cluster Analyses revealed no significant cranial variation or morphometric patterns within the specimens examined, but a …


Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker Jan 1987

Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker

University of Nebraska State Museum: Mammalogy Papers

Morphological variation was assessed within and among populations of Heteromys gaumeri using univariate and multivariate statistical analyses of external and cranial measurements. Although patterns and amount of nongeographic variation in H. gaumeri were similar to other heteromyines, geographic variation was relatively conservative. Mean values of most characters were statistically homogeneous among localities and spatially unpatterned. Consequently, no association was found between levels of within- and among-sample variation for individual characters (the "Kluge-Kerfoot phenomenon"). Populations of H. gaumeri were chromosomally monomorphic. The lack of morphological and chromosomal variation in H. gaumeri contrasts sharply with patterns in other heteromyines. Heteromys gaumeri is …


The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell Jan 1987

The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell

Masters Theses

Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones Dec 1986

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

As in previous lists, orders, families, and genera are listed in conventional phylogenetic sequence mostly following Hall (1981) but, in a departure from previous lists, species are entered alphabetically within each genus. This will facilitate use of the checklist by those unfamiliar with intrageneric taxonomy. Some assemblages are not well enough understood to create a meaningful hierarchy at the specific level.

“On Our Nebraska Records," Revisited, Wayne J. Mollhoff Dec 1986

“On Our Nebraska Records," Revisited, Wayne J. Mollhoff

Nebraska Bird Review

At the second annual meeting of the NOU, Dr. Robert H. Wolcott, one of our founders, presented a paper titled “On Migration Records and On Our Nebraska Records” (Proc. NOU 2:69, 1901), which included a plea for better documentation. He said, in part, “These problems must be met and answered in a spirit of scientific accuracy, if our conclusions are to carry weight with those living outside our borders. We must know what we know and record only what we know we know. We must be open at all times to conviction, but at the same time we must …

Proximity Nesting: The Great Horned Owl And Red-Tailed Hawk, Steve Shupe

Nebraska Bird Review

Introduction: Forty-two nests of the Great Horned Owl (Bubo virginianus) and 78 nests of the Red-tailed Hawk (Buteo jamaieensis) were surveyed during a three-year ecological study (1982–84). In 11 instances nests of the two species overlapped the hunting areas of the other. Home ranges, in which most hunting takes place, have been defined by various authors (Miller, 1930; Baumgartner, 1939; Hagar, 1967). For this study Hawks and Owls nesting within one-half mile of each other were compared. The proximity nesting of these two species seemed likely to increase the possibility of predation upon the young of …


Writing A Documentation, Barbara L. Wilson Dec 1986

Writing A Documentation, Barbara L. Wilson

Nebraska Bird Review

As the previous article makes clear, the written documentation helps birdwatchers communicate clearly about unusual sightings. Preparing the report can even add to the excitement of the event as one settles into a comfortable chair with the field notes and paper, chortling “Wait ‘til they read about this!” Then one relives the whole experience while organizing one’s thoughts for writing. Those field notes are an important part of the process, for they keep small but critical details accurate. Train yourself to take some kind of notebook or paper into the field, though in a pinch the margin of a field …


Cassin’S Sparrow In Garden County, Thomas E. Labedz Dec 1986

Cassin’S Sparrow In Garden County, Thomas E. Labedz

Nebraska Bird Review

On 21 May 1986, while searching for evidence of breeding birds in atlas block 2G04 near Lisco, Garden County, Nebraska, I discovered a Cassin’s Sparrow (Aimophila cassinii). This sighting was at 5:20 PM Mountain Daylight Time, along the county road in the northeast corner of Section 11. I was driving slowly down the road and stopped to observe an odd sparrow. I nearly drove past, thinking it was another Grasshopper Sparrow (Ammodramus savannarum), which I had heard and seen all day. The sparrow, which appeared larger than a Grasshopper Sparrow, was perched on the low wire …

Sharp-Tailed Sandpiper And Ivory Gull Reported, Sandy Kovanda, Jim Kovanda, Bill Otto, Eldon Marsh, Barbara Marsh

Nebraska Bird Review

SHARP-TAILED SANDPIPER. On 12 October 1986 we saw an unusual sandpiper, in company of three dowitchers, on the east side of Nebraska Highway 15, about half the distance between the Platte River and Octavia, Butler County. We thought the bird to be a juvenile Sharp-tailed Sandpiper (Calidris acuminata).

IVORY GULL. On 12 October 1986 we were birding six miles east and half a mile south of Brunswick, Antelope County. . . . We were sitting in our vehicle at the edge of the road, facing south, when a white gull appeared. . . . [W]e identified this bird …

Bears and Men: A Gathering, William Mills, 108 pp., 9¼ x 9¼, Algonquin Books of Chapel Hill, Chapel Hill, NC, cloth $24. 95. The author’s pictures, mostly of polar bears, but with a few of seals, arctic fox, men and their machine, and two of Ptarmigan, are probably more important than the text, which describes a trip out from Churchill in a tundra buggy towing a dormitory accommodation, both supposedly (but not too) bear-proof. The trip was organized for those who were interested in photographing polar bears under relatively natural conditions. In the course of the narrative the author …

Avian Cholera In The Panhandle, 1985–1986, Stephen M. Kerr Dec 1986

Avian Cholera In The Panhandle, 1985–1986, Stephen M. Kerr

Nebraska Bird Review

Between 28 November 1985 and 14 February 1986, over 2,500 waterfowl, 48 Wild Turkeys, and at least one Bald Eagle died due to avian cholera in an area from 5 miles west of Scottsbluff, Nebraska, to 5 miles west of Lingle, Wyoming.

On 28 November a severe snowstorm blanketed the North Platte River valley with 10 inches of snow and wind chills of –20°F. An estimated 50,000 Mallards were concentrated 5 miles west of Scottsbluff, at the headwaters of Spring Creek. The area consists of 2 small dredged channels, 10 feet wide and less than 3 feet deep, and surrounded …

1986 Fall Field Day Dec 1986

1986 Fall Field Day

Nebraska Bird Review

The 1986 Fall Field Day was held at the 4-H Camp at Halsey National Forest on 4 and 5 October. The cloudy, rainy weather, which had been rather general over the state the previous few days, cleared up (the last rain at Halsey was late Friday night), and Saturday and Sunday were clear, which pleased the 51 who attended. Of the rare bird reports submitted, the Lesser Goldfinch, by Jim Minyard, was ranked first, and the Laughing Gull, by Paul and Karla Kaufman, the Prairie-Chickens at Omaha, by Douglas Fritz, and the King Rail, by Wayne Mollhoff, were ranked next. …
