Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways Dec 1981

Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for southwestern populations, and the name Blarina carolinensis is here restricted to short-tailed shrews in the southeastern United States.


Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways Dec 1981

Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

The Texas pocket gopher (Geomys personarus), which occupies a range in southern Texas and extreme northeastern Tamaulipas, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, secondary sexual, individual, and geographic variation. Significant differences were found among the three age classes and between the sexes for 12 of 13 cranial measurements. Males displayed higher individual variation than females. Distributions of the six previously recognized subspecies (fallax, fuscus, maritimus, megapotamus, personatus, and streckeri) were examined. An additional subspecies is recognized and described. Of the seven subspecies of G. personatus, fuscus and streckeri form a group distinct ...


Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter Dec 1981

Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter

Mammalogy Papers: University of Nebraska State Museum

Significant levels of secondary sexual variation and expected levels of individual variation were demonstrated in all samples of Molossus molossus from Jamaica, Guadeloupe, and Trinidad examined with univariate analyses. Significant morphometric differences were demonstrated among samples of Molossus molossus that originated from geographically close localities on the same island. Using multivariate techniques, broader patterns of geographic variation were demonstrated among the Antillean populations of M. molossus.


1981 Fall Field Day Dec 1981

1981 Fall Field Day

Nebraska Bird Review

About forty people participated in the 1981 Fall Field Day, which was scheduled from noon Saturday 3 October to noon Sunday 4 October, but which was anticipated by early arrivals Friday and on Saturday morning. The weather was windy and cool, the skies overcast much of the time, with some rain Saturday afternoon, and Sunday morning overcast so that it was hard to get colors. But almost as soon as the meeting broke up Sunday noon the sky cleared and everybody went home in bright sunshine. There was a slide show Saturday night. Of the reports on unusual species, submitted ...

Nebraska Bird Review

DIXON COUNTY. In mid-March 1981 there were thousands of Snow Geese on the Missouri near Ponca, also Canadas, and we saw 6 White-fronteds up close in a plowed field. We also saw lots of ducks: Pintails, Ring-necks, Redheads, Mallards, and others. We saw Field Sparrows, and in town White-breasted Nuthatches, Robins, and Starlings were everywhere.

Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways Nov 1981

Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla from Phyllonycteris are in the general range of values that characterize congeneric species of mammals. Immunological distance values for the species Glossophaga soricina, Monophyllus redmani, Anoura caudifer, Leptonycteris sanborni, Choeroniscus minor, and Hylonycteris underuoodi indicate that these taxa are approximately equidistant from the Brachyphyllinae. Immunological comparisons of Glossophaga and Monophyllus to Anoura, Leptonycteris, Choeroniscus, and Hylonycteris indicate ...


Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker Oct 1981

Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker

Mammalogy Papers: University of Nebraska State Museum

Mice of the genus Peromyscus are found in virtually every habitat type in Guadalupe Mountains National Park in West Texas. Because of their abundance and wide distribution, they comprise an important component of the park's ecosystem. The first known specimens of Peromyscus from the area now included in the park were collected by Vernon Bailey in 1901 (Bailey, 1905). He collected specimens of Peromyscus boyIii in Dog and McKittrick canyons. Davis (1940) collected P. leucopus at Frijole in 1938 and P. boylii in The Bowl in 1938 and 1939. Davis and Robertson (1944) reported collecting P. pectoralis from along ...


Aquatic Oligochaeta Of Mud Lake, And Its Inlet And Outlet Stream, Michael E. Smith, Jerry L. Kaster Oct 1981

Aquatic Oligochaeta Of Mud Lake, And Its Inlet And Outlet Stream, Michael E. Smith, Jerry L. Kaster

Field Station Bulletins

Aquatic invertebrates of Wisconsin have been studied extensively, but until recently, little work has been done with aquatic oligochaetes (segmented worms). Much of the previous work was primarily concerned with the tubificid fauna of the Great Lakes (Hiltunen 1961; Howmiller 1972; Howmiller and Beeton 1910; Spencer 1980). Also, Howmiller (1914) described the aquatic Oligochaeta found in the inland waters of Wisconsin, and Howmiller and Loden (1916) provided additional information which contains the most current list of species found in Wisconsin. A study was carried out during May and June 1980 at the University of Wisconsin - Milwaukee Field Station to determine ...


Patterns Of Seedling Establishment In An Old Field, Patrick O'Donnell, Forest Stearns Oct 1981

Patterns Of Seedling Establishment In An Old Field, Patrick O'Donnell, Forest Stearns

Field Station Bulletins

Within 100 years after settlement began (ca. 1830), most forest land in the Milwaukee area had been influenced by agriculture. When the land was cleared for cultivation, trees were occasionally left along property boundaries, on steep slopes or in depressions. These trees served to shade the farmer and his livestock and break the wind. Beginning in the 1930's, urbanization and other changes in land use have resulted in abandonment of cultivated fields and pastures and their regrowth to forest or conversion to other uses. The isolated trees provided a continuing source of tree seed. The presence of an isolated ...


Vascular Plants Near The Margins Of Their Range In Cedarburg Bog. Part 1. Gymnosperms And Monocots, James A. Reinartz, Gay E. Reinartz Oct 1981

Vascular Plants Near The Margins Of Their Range In Cedarburg Bog. Part 1. Gymnosperms And Monocots, James A. Reinartz, Gay E. Reinartz

Field Station Bulletins

Marginal populations are those located at the extreme or periphery of a species' range. In the context of this paper, marginal populations refer to a geographical periphery rather than to possible ecological margins. A wide ranging species may be composed of several different varieties or ecotypes. Marginal populations of plants are of special interest to plant taxonomists, ecologists, ecological geneticists and biogeographers because they may exhibit different characteristics than more centrally located populations. This is likely because plants at the boundaries of their species' range may experience extreme ecological conditions beyond which they cannot survive.

Additional Christmas Count

Nebraska Bird Review

Additional Christmas Count

Information on the Norfolk Christmas Count was received after the tabulation was published (NBR). The count was taken 20 December 1980 from 7 AM to 5:30 PM, temperature was from -1 ° to 15° F, and wind from the south at 8 mph. The count was centered on the intersection of US 275 and US 81 (13th Street and Norfolk Avenue). Since the 15 December 1979 count was not included in the 1979 tabulation (NBR 48:15) it is also included (the first figure is for 1979).

Notes [September 1981]

Nebraska Bird Review

GREAT-TAILED GRACKLE. The note on Great-tailed Grackles at Columbus (NBR 49:28) incorrectly described them as "nesting"; Prof. Holtz's report said only "a pair of Greattailed Grackles". This error apparently came from overloading memory before typing in transcribing the report.

CHASE COUNTY. Iola Pennington, Wauneta, made five reports on her observations at Wauneta, Enders Reservoir, and Champion from 25 February to 26 April 1981. The birds on the first report had been there earlier, and except for the last report only the more notable species were reported: Geese: Canada 2/25, Snow 4/2; Mallard 2/25-4/26, Gadwall ...

Radial-Maze Performance In The Rat Following Lesions Of Posterior Neocortex, Melvyn A. Goodale, Robert H.I. Dale Sep 1981

Radial-Maze Performance In The Rat Following Lesions Of Posterior Neocortex, Melvyn A. Goodale, Robert H.I. Dale

Scholarship and Professional Work - LAS

The present experiment was designed to investigate the role of posterior neocortex (areas 17, 18 and 18a) in the maintenance of performance on the radial maze. Following training to criterion on the 8-arm radial maze, rats received either sham operations, bilateral eye enucleations, lesions of posterior neocortex, or combined enucleations and lesions of posterior neocortex. While the enucleated animals with intact brains showed a slight, but significant performance decrement relative to the sham-operated group, the other two groups, with lesions of areas 17, 18 and 18a, each showed a massive deficit. This large deficit was observed even in the group ...

Remembrance Of Places Lasts: Proactive Inhibition And Patterns Of Choice In Rat Spatial Memory, William A. Roberts, Robert H.I. Dale

Scholarship and Professional Work - LAS

A series of experiments was carried out to evaluate the notion that rats given a sequence of massed daily trials on the radial maze reset working memory at the end of each trial by deleting its contents. Although curves presented by D. S. Olton [Scientific American, 1977, 236, 82-98: In S. H. Hulse, H. Fowler, & W. K. Honig (Eds.), Cognitive processes in animal behavior, 1978, Hillsdale, N.J.: Erlbaum] show that rats return to errorless performance at the beginning of each trial after the first, the fact that accuracy falls less rapidly over choices on Trial 1 than on subsequent ...


Some Aspects Of Amino Acid Regulation In The Tobacco Hornworm, Manduca Sexta, J. Michael Henry Aug 1981

Some Aspects Of Amino Acid Regulation In The Tobacco Hornworm, Manduca Sexta, J. Michael Henry

Masters Theses

The nature and roles of the high free amino acid levels found in the haemolymph of insects is poorly understood. In order to elicit aspects of the regulation and metabolism of haemolymph free amino acids, we have measured the concentrations, half-lives, turnover rates and rate of incorporation into haemolymph proteins for eight amino acids in the tobacco hornworm Manduca sexta immediately prior to and throughout the larval-pupal transformation. Throughout this period the concentrations of alanine, arginine, glutamate, histidine, leucine, lysine, proline and valine each exhibited stage specific variations seemingly independent of blood volumes and levels of other amino acids. Half-lives ...

Results Of The Alcoa Foundation-Suriname Expeditions. Vi. Additional Chromosomal Data For Bats (Mammalia: Chiroptera) From Suriname, Robert J. Baker, Hugh H. Genoways, Paisley A. Seyfarth

Mammalogy Papers: University of Nebraska State Museum

As part of ongoing studies of the bats of Suriname, karyotypic information is presented for seventeen species. Chromosomal data are presented for the first time for Peronymus leucopterus, Peropteryx macrotis, Mimon bennettii, Artibeus concolor, Furipterus horrens, and Thyroptera discifera. Additional chromosomal data are presented for eleven other species of bats for which some information was available previously.


Reproduction In A Nebraska Sandhills Population Of The Northern Prairie Lizard Sceloporus Undulatus Garmani, Royce E. Ballinger, Dale L. Droge, Steven M. Jones Jul 1981

Reproduction In A Nebraska Sandhills Population Of The Northern Prairie Lizard Sceloporus Undulatus Garmani, Royce E. Ballinger, Dale L. Droge, Steven M. Jones

Papers in Herpetology

The reproductive cycle of Sceloporus undulatus was studied in western Nebraska. Females mature in the 1st year following hatching at a size of 45 mm SVL. Two clutches averaging 5.5 eggs each are produced. Egg sizes are similar to other grassland populations and contain approximately 650 g-cal. per egg. Egg weight to body weight ratios of 0.33 were the highest which have been reported for any S. undulatus population. Variation in life history characteristics within and between grassland and eastern woodland habitat types are explicable given a knowledge of the growing season, predation intensity and demographic environment.

Herpetofauna Of Mormon Island Preserve Hall County, Nebraska, Royce E. Ballinger, Steven M. Jones, J. W. Nietfeldt

Papers in Herpetology

Introduction: Studies of reptiles and amphibians in the grasslands of North America have primarily concerned the compilation of state faunal lists (e.g. Smith 1956, Hudson 1942, Webb 1970, Wheeler and Wheeler 1966). There have been a large number of reports on range extensions to augment this basic data. With the exception of the extensive studies by Fitch (1954, 1956, 1958, 1960, 1963) primarily on reptiles and Bragg (1940a, 1940b, 1943, 1953) primarily on anurans, the ecology of the herpetiles of the grasslands are not well studied. Lynch (1978) provided an excellent analysis of the ecological distributions of the leopard ...


Wintering Bald Eagles At Southwest Nebraska Reservoirs, David E. Busch Jun 1981

Wintering Bald Eagles At Southwest Nebraska Reservoirs, David E. Busch

Nebraska Bird Review

As a part of Water and Power Resources Service (formerly Bureau of Reclamation) compliance with endangered species mandates, a study of Bald Eagle use of Lower Missouri Region reservoirs was initiated during the winter of 1979. The author, headquartered in McCook, surveyed a number of reservoirs in Kansas and Nebraska, including Nebraska's four southwest reservoirs.

While wintering Bald Eagles on the Platte River, Harlan County Reservoir, and the Lewis and Clark Lake area have been the subjects of previous studies, the southwest reservoirs have received little such attention. Since wintering Eagle populations at these four reservoirs are relatively low ...
