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.

The Ornithogeography Of The Great Plains States, Paul A. Johnsgard

Paul Johnsgard Collection

It has long been recognized that the Great Plains represent a major transition zone in the distribution patterns of North American birds; field guides traditionally have treated the 100° W. longitude meridian as a convenient dividing line between eastern and western faunas. Furthermore, this line rather neatly bisects the political subdivisions of the Great Plains, namely the "plains states" extending from North Dakota southward through South Dakota, Nebraska, Oklahoma, and Texas. Of these, Texas is the least typical, its climate and fauna is strongly influenced by the Gulf Coast on the east and the Chihuahuan desert on the west. As …

Evaluation Of Body Size Parameters In Elite Angus Cattle, Wilson Stone

Masters Theses & Specialist Projects

The cattle shown at the prestigious All-American Angus Futurity were studied in order to evaluate the relationship between various body measurements. The measurements taken included wither height, hip height, body length, fat thickness,and weight. Also, these measurements were analyzed in order to determine if Angus cattle had gained in genetic frame size. Data were collected for the 805 animals shown in the years 1974 through 1978.

The cattle were grouped into classes based upon sex and age prior to any statistical procedures being performed. Means of classes were used in order to evaluate sex differences and bulls were found to …

The Effect Of Developmental Temperature On Morphology, Energy Metabolism, Growth Hormone And Thyroid Stimulating Hormone In Long-Evans Rats, Dana Elizabeth Quinn

Dissertations and Theses

Long-Evans rats were raised from birth to eight weeks of age at 5°C, 20°C and 30°C. Blood was taken from animals two to eight weeks of age and assayed for growth hormone and thyroid stimulating hormone. The 30°C reared rats were found to have the longest ear, tail and hind limbs, followed by the 20°C reared rats. The 5°C rats were found to have the shortest ear, tail and hind limb. The 30°C and 5°C reared rats were found to have similar masses at the termination of the experiment. The 20°C reared rats had the smallest mass. Differences in size …

The Triumphant Trumpeter: Once Reduced To A Few Bevies, This Magnificent Swan Is On The Road To Recovery, Paul A. Johnsgard

Papers in Ornithology

Largest of all the swans and heaviest of North American birds, the trumpeter swan is on the increase. Once common and widespread over much of the western United States, the bird was a winter resident of the lower reaches of the Mississippi Valley, Louisiana, and Texas. During the last century, however, trade in swan-skins—-used to make powder puffs and writing and drawing quills—-and the sale of eggs to collectors had a heavy impact on the species. In the period from 1853 to 1877, for example, London sales of trumpeter swan-skins imported through the Hudson's Bay Company totaled nearly 18,000, an …

An Analysis Of Hair Structure And Its Phylogenetic Implications Among Heteromyid Rodents, Jacqueline A. Homan, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Hair morphology of 36 species of the family Heteromyidae including the genera Dipodomys, Perognathus, Microdipodops, Liomys, and Heteromys was studied using both light and scanning electron microscopy. Variables investigated included length and width of hair, imbricate scale pattern, external and cross-section form of hair, and medullary characteristics. Although the hair of individual species could be characterized with detailed study, we do not believe that hair structure will be of value in evolutionary studies of this group below the generic level. The overhair of heteromyid rodents falls into two morphological types-hair which is round to oval in …

Aquatic Vascular Plants In Three Bays Of Eastern Door County, Wisconsin, Peter J. Salamun

Field Station Bulletins

Aquatic macrophytes of the western shores of Lake Michigan have received little attention from Wisconsin botanists (Ross and Calhoun, 1951; Curtis, 1959), probably because few localities are available for study. Severe wave action and unstable bottom sediments prevent the establishment of such plants in many areas of the lakeshore and intensive shoreline development has eliminated most of the hardy species which were originally present. However, three bays in eastern Door County (Rowleys Bay, North Bay and Moonlight Bay) support a considerable number of aquatic plant because they are protected from severe storms and are relatively free from human interference. This …

Predator Recognition Through Audition In The Black-Capped Chickadee (Parus Airicapillus), Karen Apel

Field Station Bulletins

The behavior of bird species toward a potential predator has been investigated in various studies in which a live or model predator has been presented to the subject(s). However, with the exception of a few reports of the responses of birds to imitated calls of different birds of prey (e.g., Miller, 1952), little work has been done on how a bird's behavior is influenced by the vocalizations of predators. The purpose of this study was to record the behavior of free-living Black-capped Chickadees (Parus atricapillus) when tape-recorded calls of predatory birds were played back to them.

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

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 …

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 …

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, …

Movement Ecology And Activity Behavior Of Black Bears In The Great Smoky Mountains National Park, David L. Garshelis

Masters Theses

Movements and activity behavior of 29 radio-collared black bears (Ursus americanus) were monitored between July 1976 and December 1977 in the Great Smoky Mountains National Park. Many bears exhibited home ranges with abrupt seasonal changes, especially between summer and fall. The timing and extent of these range shifts were influenced by sex, age and food availability. During good mast years, the fall ranges of many males overlapped considerably in an area of abundant oaks, while during poor mast years, social intolerance may force many subordinate males outside the Park boundaries in search of food. Fall movements increased the …

Mercury, Copper, And Zinc In Selected Ichthyofauna Of Lower Chesapeake Bay And Hampton Roads, Virginia, W. Bruce Aitenhead

OES Theses and Dissertations

Anchovys, croaker, spat, summer flounder and hogchokers were collected monthly to seasonally from November 1972 to October 1973 at three locations in the southern Chesapeake Bay region of Virginia.

The concentrations of mercury, copper and zinc were determined by atomic absorption spectrophotometry in whole fishes. Metal concentration varied with species and location. Anchovys had the highest mean concentrations of mercury and zinc while hog- chokers had the highest mean copper concentration. Mercury levels exceeding O.5 ppm were observed in species from all three loca- tions, but maximum heavy metal concentrations per species were highest in Craney Island fishes.
