Differentiation Of Fourth And Early Fifth Stages Of Parascaris Equorum (Goeze, 1782) Nematoda: Ascaridoidea, P. A. Pilitt, J. R. Lichtenfels, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of Parascaris equorum of horses was studied; light and scanning electron microscopy were used. Late fourth-stage larvae have narrow, rectangular lips bearing few, large. triangular, irregularly spaced denticles and the lips are not markedly set off from the body. The cutick of the late fourth stage is completely transversely striated, with incomplete longitudinal ridges creating a brickwork pattern; longitudinal alae are present. Total body lengths of fourth-stage larvae range from 10 to 32 mm. A single molting fourth-stage male was found to be 33 mm long. Early fifthstage nematodes have wide, trilobate lips with a deep transverse groove …

Morphometrics [Of Phyllostomatid Bats], Pierre Swanepoel, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In this paper, we have attempted to cite all relevant literature in which mensural
data pertaining to phyllostomatid bats has appeared. We are not so naive as to
believe this goal was reached, but we do believe most pertinent publications
are listed, including all major works relating to each species. This information
serves as a summary of what currently is known concerning morphometrics of
phyllostomatids and hopefully provides a basis for future morphometric studies
of members of the family.

The American Wood Quails Odontophorus, Paul A. Johnsgard

Paul Johnsgard Collection

It is ironic that the genus of New World quails that not only has the greatest collective geographic range (from central Mexico to northeastern Argentina) but also the largest number of species (12 or more, varying with the authority), is one of the least known groups of American gallinaceous birds. This is in large measure the result of the fact that all of the species are forest-adapted, and generally are associated with tropical to sub-tropical communities, where opportunities for easy observation are virtually absent.

Not only is this the largest genus of the subfamily Odontophorinae, but also the species tend …

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 …

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 a …

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.

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 …

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 …

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 …

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

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 …

Distribution Of Two Species Of Long-Eared Bats Of The Genus Myotis On The Northern Great Plains, J. Knox Jones Jr., Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Two long-eared species of the cosmopolitan bat genus Myotis, the long-eared myotis (Myotis evotis) and the fringe-tailed myotis (Myotis thysanodes), have been known for many years from the Northern Great Plains. Material acquired in the last decade or so, however, reveals a somewhat different distributional pattern for the two species than had been supposed on the basis of specimens obtained earlier, some of which have been misidentified in the published literature.

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 …

Expected Economic Responses To Selection For Direct And Fetal Genetic Effects, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Expected responses in direct and fetal genetic values due to selection of heifers or bulls were computed for various combinations of heritabilities of direct and fetal effects, genetic correlations, economic weights, and kinds of relatives' records. If the economic weights are 1:3 for direct and fetal effects, then records of mates of the sire should be used for selection of both heifers and bulls for the heritabilities .16 to .32. If the economic weights are 1:1, use of records of the mates does not appear important for selection of bulls or heifers. Reliable estimates of genetic covariance and variances of …

Bats From Southern Haiti, David Klingener, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A collection of 450 specimens of bats from the Departement du Sud, Haiti, is described. Fifteen of the 17 species previously recorded from Hispaniola are represented, and Noctilio leporinus is reported from Haiti for the first time. Reproductive information for the months of January, May, June, August, and December is presented. Macrotus waterhousii is seasonally monoestrous, as on the mainland. The two species of stenodennines, Artibeus jamaicensis and Phyllops hailiensis, do not show bimodal seasonal polyestry as do stenodermines in Central America. Monophyllus redmani and the phyllonycterines may be seasonally monoestrous. Differences in reproductive biology between Haitian bats and …

Pasteurellosis Of Fishes, G. L. Bullock

United States Fish and Wildlife Service: Publications

Septicemic infections of marine and estuarine fishes caused by Pasteurella have been known since the early 1960's. A Pasteurella caused a massive mortality of white perch (Morone americanus) and striped bass (M. saxatilis) in Chesapeake Bay in 1963 (Snieszko et al. 1964), and of cage-cultured yellowtails (Seriola quinqueradiata) in Japan in 1964 (Matsusato 1975). Pasteurellosis has spread to most areas in Japan where yellowtails are propagated and is one of the important bacterial diseases of the species. In 1972, 360 metric tons of yellowtails were lost. The terms bacterial tuberculoidosis and pseudotuberculosis (Kubota et …

First Nesting Record Of The Caspian Tern In North Dakota, James F. Herman, Rodney A. Schmidt, Karen J. Wilson

United States Fish and Wildlife Service: Publications

On June 28, 1977, we observed a single pair of Caspian terns (Sterna caspia) with two young on an island in Lake Williams in central North Dakota. This is the first confirmation of actual nesting by the Caspian tern in the State. Previously, breeding records had been postulated from sightings during the breeding season (Kantrud 1973; Robert Randall, personal communication; and Rohrt Stewart, personal communication).

Lake Williams is a shallow, saline, 420-hectare lake located near the town of Turtle Lake in east-central Mclean County. Mean depth during the breeding season (May-June) can range from 0 to 50 centimeters. …

Review Of The Pheasants Of The World, Paul A. Johnsgard

Papers in Ornithology

This book, one of Delacour's three major monographs on avian families (the others being the Anatidae and, with Dean Amadon, The Cracidae), was originally published in 1951 but went out of print in the late 196Os, when it quickly became a collector's item. At the request of the World Pheasant Association, an avicultural organization concerned with galliform conservation, Delacour undertook a revision of the book, and a new colored plate has been prepared by R. David Digby. That Delacour, now in his late 80's, should undertake such a project at all is a testimony to the amazing vigor and enthusiasm …

Estimation Of Heritabilities For Weight, Height And Front Cannon Bone Circumference Of Thoroughbreds, R. L. Hintz, H. F. Hintz, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

A total of 19,833 records on 1,992 Thoroughbred foals out of 813 dams and by 365 sires was used to estimate heritability of weight, height at withers, and front cannon bone circumference. Measurement ages ranged from 0 to 174 days. Records were adjusted for the fixed effects of age of dam, sex of foal, and month and year of birth of the foal. Body weight, height at withers and front cannon bone circumference tended to be rather lowly heritable during the first few months but were moderately to strongly heritable by 1 year of age.
