Additional Comments On Reproductive Strategies And Population Fluctuations In Microtine Rodents, Michael S. Gaines, William M. Schaffer, Robert K. Rose
Additional Comments On Reproductive Strategies And Population Fluctuations In Microtine Rodents, Michael S. Gaines, William M. Schaffer, Robert K. Rose
Biological Sciences Faculty Publications
Recently, Schaffer and Tamarin (1973) proposed a model relating changes in reproductive effort (RE) to fluctuating densities in microtine rodents (lemmings and voles). They assumed (and presented data supporting this assumption) that the major effect of increased crowding would be a reduction in survival among prereproductives, thereby lowering the effective fecundity (Schaffer and Rosenzweig 1977) of their parents. As a consequence, Schaffer and Tamarin argued that the optimal reproductive expenditure, E(N), should decline with increasing population size, N. They also deduced the shape of the zero-growth isocline, N*(E), for differing levels of RE and plotted both E(N) and N*(E) on …

Some Physical And Biological Factors Affecting Red-Tailed Hawk Productivity, Stewart Wayne Janes
Some Physical And Biological Factors Affecting Red-Tailed Hawk Productivity, Stewart Wayne Janes
Dissertations and Theses
Various physical and biological factors affecting annual productivity in a Red-tailed Hawk population in north-central Oregon were investigated. The percentage of the population successfully fledging one or more young was the most important factor in determining the number of young fledged per pair in a given year. Neither clutch size nor the number of young fledged per successful nest varied significantly. Percent pair success was correlated with several January weather variables. A cold and dry January is positively correlated with Red-tailed Hawk productivity. This is apparently related to the onset of rapid vegetative growth and this in turn is positively …
Revision Of The Antillean Bats Of The Genus Brachyphylla (Mammalia: Phyllostomatidae), Pierre Swanepoel, Hugh H. Genoways
Revision Of The Antillean Bats Of The Genus Brachyphylla (Mammalia: Phyllostomatidae), Pierre Swanepoel, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Nongeographic and geographic variation have been analyzed in the genus Brachyphylla. which belongs to the Antillean endemic subfamily Phyllonycterinae of the family Phylloslomatidae. Males were found to be generally larger than females: therefore, the sexes were analyzed separately for geographic variation. External measurements except length of forearm were found to displaya high degree of individual variation. They were not used in subsequent analyses. Of cranial measurements, greatest length of skull and condylobasal length showed the least individual variation, whereas palatal length, postorbital breadth (in samples from west of the Mona Passage only), and rostral width at canines showed relatively …

Review Of The Desert Pocket Gopher, Geomys Arenarius (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
The desert pocket gopher (Geomys arenarius), which occupies a restricted geographic range in Texas, New Mexico, and Chihuahua, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, sexual, individual, and geographic variation. Significant differences were found among different age classes and between sexes. Males displayed higher individual variation than females and external measurements were more variable than cranial measurements. Two subspecies--G. a. arenarius and G. a. brevirostris--were recognized after analyses of geographic variation.
Bats Are Beautiful, Hugh H. Genoways, Robert J. Baker
Bats Are Beautiful, Hugh H. Genoways, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
The thought that "Bats are Beautiful" may bring a smile to your face as you think of these ugly little creatures hanging from the ceilings of haunted houses and flying around deserted bell towers at midnight. You may also remember old wives tales such as "all bats have rabies" or "bats try to fly into women's hair." None of these things is completely true, and some of the tales have no basis in fact whatsoever.
Actually, the 875 species of bats form a unique Order of mammals (those animals possessing hair at least somewhere on their bodies), since they are …
The Fall And Winter Food Habits Of The Black Bear (Ursus Americanus) In The Great Dismal Swamp Of Virginia, Francis Leonard Daniel
The Fall And Winter Food Habits Of The Black Bear (Ursus Americanus) In The Great Dismal Swamp Of Virginia, Francis Leonard Daniel
Biological Sciences Theses & Dissertations
A study was conducted on the food habits of the black bear (Ursus americanus) in the Great Dismal Swamp of Virginia. A total of four stomachs and 42 scats were analyzed. Four samples were collected from September and October of 1975, and the remainder of the samples were collected from September 1976 to February 1977. The study was conducted to obtain information vital to the management of this species in the Great Dismal Swamp. Vitis spp. was the primary food item during the fall comprising 43% of the total diet, followed by fruits of Diospyros virginiana and Asimina triloba, each …

Notes On Distribution Of Three Species Of Mammals In South Dakota, J. Knox Jones Jr., Jerry R. Choate, Robert B. Wilhelm
University of Nebraska State Museum: Mammalogy Papers
No definitive account of the mammals of South Dakota has been published and, therefore, the distribution of species occurring in that state is relatively poorly documented save for several geographically restricted faunal studies (Andersen and Jones 1971, on Harding County, Findley 1956, on Oay County, and Turner 1974, on the Black Hills, for example). Our own work in South Dakota began almost two decades ago, but in recent years has focued primarily on the unique environmental area in southern Bennett County. Three species of mammals for which we have important unpublished distributional records from the state are the eastern mole, …
A Mid-Continent Irruption Of Canada Lynx, 1962-63, Harvey L. Gunderson
A Mid-Continent Irruption Of Canada Lynx, 1962-63, Harvey L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
There was a mid-continent irruption of the Canada lynx (Felis lynx) population and subsequent extensive movement into non-lynx habitats during the years 1962-1963. Lynx were found in the prairie provinces of Canada and the prairie areas of Minnesota, and North and South Dakota. They were also found in urban areas such as Minneapolis and St. Paul, Minnesota: Winnipeg, Manitoba: and Calgary, Saskatchewan, Canada. Causes for the irruption remain unknown but speculations include primarily a change in snowshoe hare population, disease, extensive forest fires and extensive spraying. Unusual behavior seemed to be most often reflected by a lack of …

Bats Of Guadeloupe, Robert J. Baker, Hugh H. Genoways, John C. Patton
Bats Of Guadeloupe, Robert J. Baker, Hugh H. Genoways, John C. Patton
University of Nebraska State Museum: Mammalogy Papers
The bat fauna of the Lesser Antillean chain is of considerable interest because it is composed of a depauperate extension of the South American fauna, species that have a widespread distribution in the Antilles, and a few species that are endemic to the Lesser Antilles (Baker and Genoways, 1978). Relative to bat speciation and diversity, Guadeloupe is probably the most important island of the Antillean chain.
This report is concerned with the natural history and systematics of the 11 chiropteran species known from Guadeloupe, three of which are endemic. Comments concerning systematic relationships are based on specimens that we collected …

An Analysis Of The Heavy Metal Content Of The Scales Of Several Fishes In Southwestern Kentucky, Thomas Dahl
An Analysis Of The Heavy Metal Content Of The Scales Of Several Fishes In Southwestern Kentucky, Thomas Dahl
Masters Theses & Specialist Projects
Scales of the stoneroller, Campostoma anomalum (Rafinesque), common shiner, Notropus cornutus (Mitchill), and the bluntnose minnow, Pimephales notatus (Rafinesque) were analyzed by means of atomic absorption spectrophotometry to determine levels of cadmium, calcium, copper, iron, lead, manganese, nickel and zinc. Metal concentrations were determined seasonally and relationship established between scale metal content and environmental water metal levels.
Calcium, iron manganese and zinc were found in all samples analyzed. Cadmium, copper, lead and nickel were not observed in measurable quantities.
Metal concentrations varied interspecifically, but most showed little fluctuation in response to increased metal content of the water. Elemental composition of …

Conflict In Outdoor Recreation, Gerald R. Jacob
Conflict In Outdoor Recreation, Gerald R. Jacob
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The causes of conflict among users of outdoor recreation resources have received little attention from recreation researchers. Knowledge of factors responsible for conflict might assist recreation planners' attempts to reduce future instances of conflict and help management focus its conflict resolution efforts. A theory of conflict is offered as the first step in systematically procuring such knowledge. A definition and characteristics of outdoor recreation conflicts are presented; four comprehensive causes of user conflicts are proposed. Ten propositions are used to link these factors to conflict and suggest future research hypotheses. The social psychological dynamics of conflict, as described here, have …
