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

University of Nebraska State Museum: Mammalogy Papers

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 Bell …

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.


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 …


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 tree …


Activity Of Moose And White-Tailed Deer At Mineral Springs, D. Fraser, H. Hristienko Oct 1981

Activity Of Moose And White-Tailed Deer At Mineral Springs, D. Fraser, H. Hristienko

Social Behavior Collection

Activity of moose (Alces alces) and white-tailed deer (Odocoileus virginianus) was studied at two natural mineral springs (licks) in Ontario during the springtime and summer of 1977 to 1980. Most adult moose appeared to use a lick during a single 1- to 5-day period in a year; some returned at intervals during the season; and all seemed drawn principally by the mineral-rich water. Some young moose remained in the lick vicinity for 3 weeks or more, and often wandered in and out of the licks, grazing herbage as well as drinking. This suggested a social as well as a nutritional …


Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech Oct 1981

Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech

USGS Northern Prairie Wildlife Research Center

The gray wolf Canis lupus occupies only about 1 percent of its former range in the lower 48 states (Mech 1974a). Most of the range is in northern Minnesota, where the resident population is classified as "threatened" by the U.S. Department of the Interior. Wolves have been and will continue to be the subject of considerable controversy in Minnesota.

The first scientific study of wolves in Minnesota was conducted by Olson (1938a,b). That and all subsequent re- search was in the Superior National Forest (SNF) of northeastern Minnesota even though wolves inhabit approximately the northern third of the state. Consequently, …

A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler Oct 1981

A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This study reports on the development and progress of a forecasting-programming model for swine inventory management and marketing decisions. This model considers interrelationships between breeding herd, feeder pig and finishing hog activities. Objectives were: 1. To structure a dynamic operational decision model for a modern farrow-to-finish swine confinement unit which conforms with economic theory, uses price and cost forecast information and is as consistent as possible with current production scheduling practices. 2. To use and test this model during a combined production and marketing decision process and to compare economic results with results of a standard strategy.


Results Of The Third High Protein-High Lysine Wheat Observation Nursery Grown In 1977, S. L. Kuhr, V. A. Johnson, P. J. Mattern, K. D. Wilhelmi Oct 1981

Results Of The Third High Protein-High Lysine Wheat Observation Nursery Grown In 1977, S. L. Kuhr, V. A. Johnson, P. J. Mattern, K. D. Wilhelmi

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third report of results from a high protein-high lysine (HP-HL) wheat observation nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Science and Education Administration, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. Advanced experimental lines distributed to breeders and cooperators in the 3rd HP-HL nursery were selected from numerous hybrid combinations of both spring and winter types. All exhibited elevated protein and/or lysine in nursery trials in Nebraska or Arizona.


Seasonal Variation In The Foraging Behavior Of Some Migratory Western Wood Warblers, Richard L. Hutto Oct 1981

Seasonal Variation In The Foraging Behavior Of Some Migratory Western Wood Warblers, Richard L. Hutto

Biological Sciences Faculty Publications

I observed the foraging behavior of four warbler species (Dendroica petechia, Oporornis tolmiei, Geothlypis trichas, and Wilsonia pusilla) in the summer in Wyoming and in the winter in Nayarit, Mexico. Of six variables (absolute foraging height, relative foraging height, vegetation density, horizontal foraging position, feeding method, and foraging substrate) believed to be potentially important in distinguishing the warbler species ecologically, the two foragingheight variables provided the greatest separation of the four species in both summer and winter. An analysis of the behavioral similarity of each species from summer to winter revealed that feeding method was the least …


Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser Oct 1981

Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser

Wildlife Population Management Collection

A nonlinear least-squares procedure is developed to estimate harvest rate and differential vulnerability in wildlife populations that are harvested with 1 segment of the population more able than another. The method requires age data by category from a series of harvests, plus information on accumulated harvest effort, and assumes that the nonharvest mortality rate is the same for the categories. The data need not be from consecutive harvests, as long as the effort is known for missing Monte Carlo simulations were done to verify the estimation procedure. An example shows the application of the method to moose (Alces alces) harvest …

Diclidophora Nezumiae Sp. N. (Monogenea: Diclidophoridae) And Its Ecological Relationships With The Macrourid Fish Nezumia Bairdii (Goode And Bean, 1877), Thomas A. Monroe, Ronald A. Campbell, David E. Zwerner Oct 1981

Diclidophora Nezumiae Sp. N. (Monogenea: Diclidophoridae) And Its Ecological Relationships With The Macrourid Fish Nezumia Bairdii (Goode And Bean, 1877), Thomas A. Monroe, Ronald A. Campbell, David E. Zwerner

VIMS Articles

Diclidophora nezumiae sp. n. is described from the gills of the rat-tail fish Nezumia bairdii (Goode and Bean, 1877) taken from the environs of Hudson Submarine Canyon in the northwest Atlantic. The host-parasite relationships were studied in the host population. The new species is most similar to small species of Diclidophora having short bodies that taper to maximum width at the level of the first pair of clamps. It may be differentiated from other species by the following: clamps wider than long, noticeably decreasing in size posteriorly; lamellate extension of sclerite b does not fuse with sclerite c1; unsclerotized diaphragm; …

Drosophila Alcohol Dehydrogenase: Developmental Studies On Cryptic Variant Lines, Gurbachan Miglani, Franklin Ampy Oct 1981

Drosophila Alcohol Dehydrogenase: Developmental Studies On Cryptic Variant Lines, Gurbachan Miglani, Franklin Ampy

Department of Biology Faculty Publications

Thirty-five cryptic variant lines were used to examine the mechanisms involved in genetic modulation of alcohol metabolism in Drosophila. Late third-instar larval, preemergence pupal, and adult stages cultured at 18 and 28 C were examined. Spectrophotometric analyses for native alcohol dehydrogenase (ADH) activity and residual ADH activity after treatment with guanidine hydrochloride and heat were performed. Differential response of cryptic variants to treatment with the denaturants during development suggested that this variation may have an adaptive significance.


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 …

Selection And Characterization Of Cole1 Plasmid Mutants That Exhibit Altered Stability And Replication., Joseph Inselburg Sep 1981

Selection And Characterization Of Cole1 Plasmid Mutants That Exhibit Altered Stability And Replication., Joseph Inselburg

Dartmouth Scholarship

This report describes a method for isolating mutants of plasmid ColE1 that exhibit unstable maintenance and altered replication characteristics. It also describes the initial characterization of four mutants isolated by that method. A chimeric plasmid, pHSG124, containing a ColE1 derivative and a temperature-sensitive replication derivative of pSC101 was mutagenized in vitro, using hydroxylamine. By adjusting the growth conditions of transformants containing the mutagenized chimeric deoxyribonucleic acid, it was possible to rapidly screen colonies and identify those that had a high probability of carrying ColE1 mutants that exhibit unstable maintenance. Of those mutants, some exhibited altered copy number or accumulated catenated …


Aggregation Behavior Of Aplomyiopsis Xylota (Diptera: Tachinidae), Frank J. Messina Sep 1981

Aggregation Behavior Of Aplomyiopsis Xylota (Diptera: Tachinidae), Frank J. Messina

Biology Faculty Publications

The tachinid A. xylota is a common parasitoid of larvae of Trirhabda virgata and T. borealis (Coleoptera: Chrysomelidae) in central New York [USA]. Flies aggregated on herbaceous vegetation along the borders between old fields and more shaded habitats (shrubby fields or woodlots). Aggregations comprised from less than 100 to a few thousand individuals, almost all of which were male. Males continuously perched and moved about in sun flecks on the vegetation and frequently grappled with each other. In the old field adjacent to the primary aggregation site, the tachinid sex ratio was strongly skewed toward females. Aggregations of A. xylota …

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 3/27, Pintail 2/254/ 2; Teal: Green-winged …
