Collections Of Recent Mammals In North America, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Mammalogy is the only systematic discipline that has previously undertaken periodic (that is, more than one) surveys of its holdings in North American collections. The first such survey (reported on by Howell, 1923) pertained to mammals in collections as of April of 1922. The report of the second survey (Doutt et al., 1945) summarized collections of mammals in North America as of 1943. The report of the third survey (Anderson et al., 1963) pertained to specimens of mammals in North American collections as of 1962. At that time, it was assumed that to prepare an updated report on North American …

A New Subspecies Of Geomys Bursarius (Mammalia: Geomyidae) From Texas And New Mexico, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

As part of a study of the systematics and ecology of pocket gophers occurring on the high plains of Texas and eastern New Mexico, numerous populations of the plains pocket gopher, Geomys bursarius, were examined karyotypically. Four chromosomal races were described from this area by Baker et al. (1973). Additional studies lead us to believe that two of these races represent an undescribed subspecies of the plains pocket gopher. In addition to karyological evidence, specimens of this subspecies are morphologically distinct from those of all contiguous populations of Geomys bursarius major, the race to which they previously were assigned. …

Mammals Of The Guadalupe Mountains National Park, Texas, Hugh H. Genoways, Robert J. Baker, John E. Cornely

University of Nebraska State Museum: Mammalogy Papers

Our survey began in late May 1973 and continued through August 1975. The objectives of our study, which was supported by the National Park Service, were to survey the mammals occurring in the Guadalupe Mountains National Park, Texas, and to correlate their distribution with major plant associations. This inventory of the natural resources of the park is preliminary to the development of any serious management program. Therefore, we present the following accounts to serve as baseline data for future mammalian work in the park and development of the master plan for the park.

Editors' Note To Biological Investigations In The Guadalupe Mountains National Park, Texas., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The Guadalupe Mountains National Park, which is located in TransPecos Texas between Carlsbad, New Mexico, and EI Paso, Texas, is one of the newest national parks being formed by the Congress in 1967. The Guadalupe Mountains and the associated Chihuahuan Desert included in the park represent a unique biological area in which a fragile biological equilibrium exists between the fauna and flora of the Chihuahuan Desert of the lowlands and the Rocky Mountains of the high elevations. The preservation of this area will depend upon sound management decisions. This volume is the result of a symposium held at The Museum …

Research In National Parks, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

This was our first involvement with research in the National Parks and we would like to make some observations concerning interactions among basic researchers, park personnel, and the philosophy on which our park systems are based. Our conclusions are not based only on our own experiences, but also on conversations with other basic researchers (especially those who contributed to this symposium) and with park personnel who have aided and worked with other researchers who were not employed by the National Park Service.

Revised Checklist Of North American Mammals North Of Mexico, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Faunal checklists provide useful ready references for many kinds of endeavors, both in the laboratory and in the field , and are particularly helpful to students. Since publication two years ago of our "Checklist of North American mammals north of Mexico" (Jones et al., 1973), demand for that list has exceeded the supply set aside for general distribution; additionally, published systematic studies in the interval necessitate several changes in the list. Principally for these reasons, we here present a revised checklist of mammalian species occurring in the Nearctic to the north of Mexico. As in this and similar earlier compilations, …

Comparison Of Artificial Substrates In Bottom Fauna Studies On A Large River, David R. Mcconville

Journal of the Minnesota Academy of Science

During the summer of 1974, five types of artificial substrates and grab sampling were evaluated for sampling efficiency in pool No. 3 of the Upper Mississippi River. A total of 35 taxa of organisms were collected by the different techniques. Ponar grab sampling collected representatives of only eight taxa, whereas concrete block samplers collected 22 taxa . Intermediate in taxonomic collection were the Hester-Dendy samplers with 21 taxa, the barbecue basket samplers with 20 taxa, the Miller samplers with 17 taxa, and conservation webbing with 12 taxa. The barbecue basket samplers were the most productive, yielding at least five times …

The Behaviour Of Swine, J. P. Signoret, B. A. Baldwin, D. Fraser, E. S. E. Hafez

Mammalogy Collection

The pig was a forest-dwelling animal from the beginning of its history. In some parts of the world it has been domesticated for at least 7000 years. The European breeds of domestic swine were derived from the local wild pig, Sus scrofa. Herds ranged in pastures and forests and kept indoors only for fattening. The breeds in the Far East were derived from another wild pig, Sus vittatus, a smaller animal with shorter legs and a higher reproductive ability (Mohr 1960; Zeuner 1963). The two types interbred readily. The modem breeds of pig evolved from different crossings between the two …

Raising Wood Ducks, Richard L. Nelson

Nebraska Game and Parks Commission: Publications

Numbered among Nature's most colorful creatures, wood ducks willingly accept a helping hand from man in establishing new homes. These birds adapt well to suitable habitat, and you can play an important part in bringing the wood duck to locations where they do not now nest. For groups or individuals who are willing to expend the effort necessary to undertake a wood duck restoration project anti see it to completion, it is an exceptional gift from today's generation to those of decades and centuries to come. Many areas in Nebraska provide suitable wood duck habitat, but do not have a …

Federal And State Regulations Pertaining To Systematic Collections. I. A Case Of Inadvertent Violation Of Federal Regulations, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

First paragraph:

On 25 April 1975, at the twenty-second annual meeting of SWAN (i.e. Southwestern Association of Naturalists), at the University of Oklahoma Biological Station, President Keith A. Arnold appointed one of us (Choate) to investigate current regulations pertaining to collection and transport of scientific specimens in the region of representation (including Mexico) or SWAN. This charge involves both Federal and State laws, several of which are undergoing change and many of which doubtlessly are not familiar to the membership of SWAN. In order that SWAN members might be made aware of these regulations and not unwittingly commit violations, it …

Karyotype Of Geomys Pinetis (Mammalia: Geomyidae), With A Discussion Of The Chromosomal Relationships Within The Genus, S. L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Summary. Four of the five subspecies of Geomys pinetis were karyotyped. All specimens examined had a diploid number of 42 and a fundamental number of 80. This karyotype was compared with the described karyotypes of other species of Geomys and was considered to be derived from an ancestoral form having a karyotype of about 70 acrocentric elements.

The Histology Of The Pineal Gland In Odocoileus Virginianus, Terry Michael De Villiers

Masters Theses

A total of 26 pineal glands from the white-tailed deer were histologically examined. Five different stains were utilized to determine various cell types present in pineal tissue. Connective tissue septa divide the pineal gland into incompletely separated lobules which are supplied by a very extensive vascular system. The pinealocyte is the most numerous cell in the gland and is most easily recognized by a prominent nucleus approximately 6-8 microns in diameter. The pinealocyte cytoplasm contains many minute granules. A distinct difference was noted in the histology of the oldest age deer pineal (age 7 years) when globular granules were observed …

The Relative Attenuation Of Self-Stimulation, Eating And Drinking Produced By Dopamine-Receptor Blockade, E. T. Rolls, B. J. Rolls, P. H. Kelly, S. G. Shaw, R. J. Wood, Robert H.I. Dale

Scholarship and Professional Work - LAS

Spiroperidol, which blocks dopamine (DA) receptors, attenuated self-stimulation of the nucleus accumbens, septal area, hippocampus, anterior hypothalamus and ventral tegmental area. Dopamine is thus involved in self-stimulation of many sites (in addition to the lateral hypothalamus). The attenuation was not a simple motor impairment of the speed of bar-pressing in that the nucleus accumbens and septal self-stimulation rates were lower than those in treated animals self-stimulating at other sites (Experiment 1). Feeding was partly attenuated, and drinking was much less attenuated by the spiroperidol. Since the rats bar-pressed for brain- stimulation reward, chewed pellets to eat, and licked a tube …

University of Nebraska State Museum: Mammalogy Papers

Two species of hypopial nyrnphs of mites of the family Glycyphagidae were recovered from Heteromys gaumeri from Yucatan, Mexico. Numerous specimens of a hypopus identified as Dermacarus ornatus. Fain were recovered from the hair and skin. A single specimen of an endoparasitic hypopus identified as a new genus and species, Neolabidophorus yucatanensis, was recovered from the hair follicles. The new genus differs from similar forms of the subfamily Metalabidophorinae in having a rudimentary clasper organ represented by a median sclerite behind legs IV without external serrated claspers, structure and slightly dorsal position of the tarsal solenidia on legs …

Bats Of Margarita Island, Venezuela, With Zoogeographic Comments, James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Sixteen species of bats are reported from Margarita Island, Nueva Esparta, Venezuela. These include two species of emballonurids, one noctilionid, two mormoopids, nine phyllostomatids, one vespertilionid, and one molossid. Accounts including natural history and taxonomic comments are given for each species. The chiropteran fauna of Margarita Island is compared with the bat faunas of the adjacent Venezuelan mainland and islands off the northern coast of South America, including Trinidad and other Antillean islands. It is concluded that the chiropteran fauna of Margarita Island represents an attenuated mainland fauna.
