Results Of The Alcoa Foundation-Suriname Expeditions. Iv. A New Species Of Bat Of The Genus Molossops (Mammalia: Molossidae), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

A new species of molossid bat of the genus Molossops is described from Suriname. The new species is a member of the subgenus Molossops where it is distinguished from the other two member species, temminckii and aequatorianus, by larger external and cranial size. A single specimen of the species was taken in northern Suriname in an area of savannah and secondary forest.

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

A description of the vegetative communities in an area will provide an insight to wildlife potential and use of that area. Wildlife and its corresponding habitat are recognized as important for recreation and to the overall environmental quality of an area. The Water and Power Resources Service, Lower Missouri Region, is presently engaged in a study of the Platte River Basin, including an evaluation of wildlife habitat and associated environmental needs. Quantification of wildlife habitat along the South Platte River has been completed. Vegetation communities were described and habitat maps were prepared from color infrared aerial photographs (scale – 1:24,000). …

Provisional Checklist Of Mammals Of South Dakota, Jerry R. Choate, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Distributional patterns of mammals in South Dakota are among the most poorly known for any region of similar size in temperate North America. The only state-wide treatment of the group was the mimeographed compilation by Over and Churchill (1945), which consisted mostly of nontechnical anecdotes. Consequently, much of what is known of the distribution of South Dakotan mammals has been derived from localized inventories (Findley 1956a on Clay County ; Andersen and Jones 1971 on Harding County; Turner 1974 on the Black Hills; and Wilhelm et al. 1981 on Lacreek National Wildlife Refuge in Bennett County). These studies, supplemented with …

Additional information is provided on several species of bats already known to occur in Suriname, including Micronycteris minuta, M. nicefori, Phylloderma stenops, Tonatia …

Annotated Checklist Of Mammals Of Nebraska, J. Knox Jones Jr., Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Since the completion nearly 20 years ago of the manuscript on a distributional and taxonomic study of the mammals of Nebraska (Jones, 1964), numerous changes in nomenclature resulting from systematic studies have occurred. Additionally, five species of mammals (two bats, two shrews, and an armadillo) have been recorded as new to the state in the past few years, and one bat species (Myotis evotis) has been dropped from the list. Because scientists, conservation officials, environmental agencies, nature students, and others find up-to-date checklists of considerable use, particularly in connection with field work, we have revised the list of …

The Section Of Mammals Of Carnegie Museum Of Natural History, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

The Section of Mammals at Carnegie Museum of Natural History is responsible for the care of the collections of Recent mammals, and research on these collections. "Recent mammals?!" The capitalized word "Recent" refers to the geological time period since the last ice age (about 10,000 years ago) until the present time. Mammals are that group of animals characterized by the presence of hair at least during some time of their lives, warm blood, and the production of milk. Therefore, our work really involves living mammals with which everyone is familiar; however, our work also does include study of such recently …

Demographic And Reproductive Parameters Of The Yellow-Cheeked Pocket Gopher (Pappogeomys Castanops), Michael J. Smolen, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A population of Pappogeomys castanops simulans was live-trapped on a 3.5-ha study area in Lubbock, Texas, from September 1971 to September 1973. Seasonal and annual differences in population size were observed, with the population fluctuating between 20 and 25 gophers. Female reproductive activity began in January and continued until October, with an obvious period of recruitment lacking; however, a peak was observed in March and April. Females produced as many as three litters per reproductive season. Females born early in the year were sexually mature within the reproductive season of their birth. Females had an average survival rate of 56 …

Evolutionary Origin Of Eptesicus Lynni, Michael L. Arnold, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Currently, three species of bats of the genus Eptesicus (fuscus, guadeloupensis, and lynni) are recognized as occurring on islands in the Antilles. Of these, E. fuscus and E. guadeloupensis are believed to belong to the fuscus-group of the genus (Davis, 1966; Genoways and Baker, 1975). However, the status and relationships of E. lynni are unclear. Shamel (1945) described lynni as a member of the brasiliensis-group. On the other hand, Sanbom (1941) considered three earlier specimens of lynni as members of the subspecies E. fuscus hispaniolae (we have examined the Sanbom specimens and they are referable to …

Notes On The Natural History Of Bats From Badlands National Monument, South Dakota, John P. Farney, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Little has been published on the mammalian fauna of Badlands National Monument, a unique ecological area that encompasses parts of Jackson and Pennington counties in South Dakota. By way of example, although five species of bats are herein recorded from the Monument, only one has been reported previously - see Jones and Choate (1978), who listed two specimens of Myotis thysanodes pahasapensis from the Cliff Shelf area. Jones and Genoways (1976b), however, did report several other species from badland areas not far distant from the boundary of the Monument.

In 1970, under sponsorship of the Badlands Natural History Association and …

Apparent Chromosomal Heterosis In A Fossorial Mammal, John C. Patton, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

For the past decade, numerous investigators have attempted to explain the plethora of genetic polymorphism found in nature (see Ayala 1976). However, few researchers have been able to document how polymorphisms have been maintained, whether the polymorphisms were genic or chromosomal. Our investigations into the maintenance of a Robertsonian chromosomal polymorphism in the plains pocket goher, Geomys bursarius major, have revealed evidence that this polymorphism is maintained by differential viabilities of the three chromosomal morphs, with the heterozygote being favored.

Population Regulation In Wolves, Jane M. Packard, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The possibility of social regulation of wolf populations has been discussed in the literature for several years. Some of the first ecological studies of wolves indicated that their populations did not increase as rapidly as was theoretically possible, and that they reached a saturation point apparently not set by food. Subsequent captive studies demonstrated the existence of social mechanisms possibly capable of regulating population growth. However, the importance of these factors in wild populations has not been established. This paper has four objectives: (1) to evaluate the existing concept of "intrinsic limitation," (2) to propose that wolf population dynamics may …

Nebraska Trapping, George Schildman, Frank Andelt, Jim Brunner

Nebraska Game and Parks Commission: Publications

Fur bearers and trapping played an important role in the exploration and development of Nebraska. The harvest of our fur-bearer resource is part of every Nebraskan's heritage. Wise use of the resource and consideration for other people's property and personal rights can insure that trapping will remain a part of the heritage of future generations. The purpose of this publication is to help insure this heritage ... through the educational process. Knowledge of and respect for the resource, as well as consideration for other people, are the keys to perpetuating trapping as an outdoor activity. While primarily designed to assist …

Revised Checklist Of North American Mammals North Of Mexico, 1979, 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 more than four years ago of a "Revised checklist of North American mammals north of Mexico" (Jones et al., 1975), demand for that list has exceeded the supply set aside for general distribution; additionally, systematic studies of mammals published since 1974 necessitate changes in the list. Primarily for these reasons, a newly revised checklist of mammalian species occurring in the Nearctic to the north of Mexico is here presented. As in this and …

Distribution And Natural History Of Amphibians And Reptiles In Western Nebraska With Ecological Notes On The Herpetiles Of Arapaho Prairie, Royce E. Ballinger, John D. Lynch, Patrick H. Cole

Papers in Herpetology

Introduction: The distribution and natural history of amphibians and reptiles have been little studied in the northern states of the great plains. Relative to other vertebrate groups, the herpetofauna of grasslands is depauperate particularly at higher latitudes where temperature becomes a limiting factor to poikilotherms. Nevertheless, certain species of amphibians and reptiles are common in specific habitats and thus form a conspicuous component of the prairie fauna. The purposes of the present study were to document the distributions of herpetiles in a specified region of western Nebraska and to describe general aspects of their natural history. We hope such information …

A Study Of Nongeographic Variation In Tatera Leucogaster (Mammalia: Rodentia) From Botswana, Pierre Swanepoel, Duane A. Schlitter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Specimens of Tatera leucogaster from six localities in Botswana were tested for variation with age, secondary sexual variation, and individual variation. Of the six age classes recognized, categories I, II, and III each formed their own group, whereas cat egories IV, V, and VI were not separable on a morphometric basis and were considered to be adults. Significant secondary sexual variation was found only in depth of braincase in which females were larger. The only character exhibiting unusually high individual variation was length of posterior palatal foramen. All other characters exhibited individual variation within acceptable limits.

Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.

The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf

Nebraska Game and Parks Commission: Publications

The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …

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.

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 …

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 …
