Additional Records Of The Stenodermine Bat, Sturnina Thomasi, From The Lesser Antillean Island Of Guadeloupe, Hugh H. Genoways, J. Knox Jones

University of Nebraska State Museum: Mammalogy Papers

Sturnira thomusi was named and described by de la Torre and Schwartz (Proceedings of the Biological Society of Washington 79: 297-303, 1966) on the basis of a single male from the island of Guadeloupe, Lesser Antilles, that was captured by Richard Thomas in 1963. The holotype of S. thomasi has until now been the only known specimen of this unique species. In late July of 1974, a field party from the Museum of Texas Tech University (supported by a grant from the National Science Foundation, GB-41105) collected bats on Guadeloupe and took four additional individuals of S. thomasi, all …


A New Species Of Eptesicus From Guadeloupe, Lesser Antilles (Chiroptera: Vespertilionidae), Hugh H. Genoways, Robert J. Baker Jul 1975

A New Species Of Eptesicus From Guadeloupe, Lesser Antilles (Chiroptera: Vespertilionidae), Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

In the course of field studies on bats of the Antillean region, three specimens of the genus Eptesicus were obtained on the island of Guadeloupe in the Lesser Antilles. The nearest known populations of this genus are on Puerto Rico 500 kilometers to the west (E. fuscus wetmorei), on the northern coast of South America 850 kilometers to the southwest (E. fuscus miradorensis), and on Tobago 550 kilometers to the south (E. brasiliensis melanopterus). Study of the specimens from Guadeloupe reveals that they represent a distinct species that is most closely related to Eptesicus …


Collections Of Recent Mammals In North America, Jerry R. Choate, Hugh H. Genoways May 1975

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 Apr 1975

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. …


Editors' Note To Biological Investigations In The Guadalupe Mountains National Park, Texas., Hugh H. Genoways, Robert J. Baker Apr 1975

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 …


Mammals Of The Guadalupe Mountains National Park, Texas, Hugh H. Genoways, Robert J. Baker, John E. Cornely Apr 1975

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.


Research In National Parks, Robert J. Baker, Hugh H. Genoways Apr 1975

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 Mar 1975

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, …

Federal And State Regulations Pertaining To Systematic Collections. I. A Case Of Inadvertent Violation Of Federal Regulations, Jerry R. Choate, Hugh H. Genoways Jan 1975

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

On 25 April 1975, at the twenty-second annual meeting of the Southwestern Association of Naturalists (SWAN), at the University of Oklahoma Biological Station, President Keith A. Arnold appointed Jerry 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 was decided that SWANEWS …
