Morphometric Variation In The Tropical Pocket Gopher (Geomys Tropicalis), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The tropical pocket gopher (Geomys tropicalis). which exhibits no chromosomal or genic variation, was examined for variability at the morphometrical level. Univariate and multivariate analyses were used to determine age, sexual, and geographical variation. Significant differences were found between different age classes and between sexes. The amount of individual variation was comparable with other rodents and did not exhibit the reduced variation expressed at the chromosomal and genic levels, G. tropicalis is considered to be a monotypic species.

Comparison Of Coyote And Coyote × Dog Hybrid Food Habits In Southeastern Nebraska, Brian R. Mahan

University of Nebraska State Museum: Mammalogy Papers

The recent taxonomic study by Mahan et al. (1978) documented the occurrence of coyote (Canis latrans) x dog (c. familiaris) hybrids in Nebraska. This study, and those by Freeman (1976) in Oklahoma and Gipson et al. (1974) in Arkansas show coyote x dog hybrids, though not abundant, to be numerous in some areas. The purpose of the present study was to compare the stomach contents of coyote x dog hybrids collected by Mahan et al. (1978) from southeastern Nebraska with those of contemporary coyotes.

Stomachs of 12 coyote x dog hybrids and 16 coyotes collected November 1975 …

Federal Regulations Pertaining To Collection, Import, Export, And Transport Of Scientific Specimens Of Mammals, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The routine tasks of mammalogists whose research or curatorial activities include collecting, importing, processing, exporting, or interstate transporting of living or dead scientific specimens of mammals have become increasingly complicated by newly enacted (or more rigorously enforced) Federal regulations. These regulations were necessary largely because of the activities of non-scientists, but their provisions have had a tremendous impact on the activities of scientists (especially museum-based systematists and ecologists). Most mammalogists have expressed a willingness to comply with the regulations (although nearly all agree that administration of the permit system should be consolidated into a single office) if they can obtain …

A New Species Of Chiroderma From Guadeloupe, West Indies (Chiroptera: Phyllostomidae), Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

During the course of a study of the bat faunas of the Caribbean islands we obtained a specimen of Chiroderma from the island of Guadeloupe in the Lesser Antilles. The nearest known populations of this genus occur on Tobago and Trinidad (C. villosum and C. trinitatum). approximately 550 kilometers to the south. This specimen represents a distinct new species that appears to be most closely related to C. doriae and C. villosum. This new species is named and described.

Chromosomal Banding Patterns Of The Holarctic Rodents, Clethrionomys Rutilus And Microtus Oeconomus, C. F. Nadler, V. R. Rausch, E. A. Lyapunova, N. N. Vorontsov, R. S. Hoffman

University of Nebraska State Museum: Mammalogy Papers

Biologists have long been aware of close similarities between the mammalian faunas of northern Eurasia and northern North America (Flerov 1967; Rausch 1953, 1963; Sushkin 1925; Tugarinov 1934). This similarity is particularly strong between species of tundra and taiga ecosystems (Hoffmann and Taber 1967; Hoffmann 1974). Among the species having Holarctic distributions, the boreal red-backed vole, Clethrionomys rutilus (Pallas), and the tundra vole, Microtus oeconomus (Pallas) (Rausch, op. cit.), of the subfamily Arvicolinae (= Microtinae) (Kretzoi 1962; Repenning 1968), have wide distributions in Eurasia where they inhabit, but are not restricted to, tundra (Ognev 1950; Corbet 1966). East of the …

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 …

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, …
