Cytotypes And Morphometrics Of Two Phyllostomatid Bats, Micronycteris Hirsuta And Vampyressa Pusilla, Robert J. Baker, Hugh H. Genoways, William J. Bleier, Jerry W. Warner Dec 1973

Cytotypes And Morphometrics Of Two Phyllostomatid Bats, Micronycteris Hirsuta And Vampyressa Pusilla, Robert J. Baker, Hugh H. Genoways, William J. Bleier, Jerry W. Warner

University of Nebraska State Museum: Mammalogy Papers

As pointed out by Jackson (1971) and Patton (1972), the key to understanding mechanisms of chromosomal evolution lies in studies of chromosomal variation within populations that can hybridize. Hybrids between cytotypes contain the answer to problems of meiotic pairing and reduced fertility, as well as information concerning the nature of zones of contact. However, before detailed studies can be initiated, chromosomal races and hybrid zones must be located. Few chromosomal races have been described for bats (Baker, 1970a). Within the family Vespertilionidae, five species are known to have such races (Baker, 1970a) and races have been reported in two species …

Cytotypes And Morphometrics Of Two Phyllostomatid Bats, Micronycteris Hirsuta And Vampyressa Pusilla, Robert J. Baker, Hugh H. Genoways, William J. Bleier, Jerry W. Warner

University of Nebraska State Museum: Mammalogy Papers

Jackson and Patton stated that the key to understanding mechanisms of chromosomal evolution lies in studies of chromosomal variation within populations that can hybridize. Hybrids between cytotypes contain the answer to problems of meiotic pairing and reduced fertility, as well as information concerning the nature of zones of contact. However, before detailed studies can be initiated, chromosomal races and hybrid zones must be located. Few chromosomal races have been described for bats. Within the family Vespertilionidae, five species are known to have such races and races have been reported in two species of the family Phyllostomatidae.

Nongeographic Variation In The Long-Nosed Bat, Choeroniscus Intermedius, Hugh H. Genoways, Robert J. Baker, Bernard Wyatt Aug 1973

Nongeographic Variation In The Long-Nosed Bat, Choeroniscus Intermedius, Hugh H. Genoways, Robert J. Baker, Bernard Wyatt

University of Nebraska State Museum: Mammalogy Papers

Of the 12 measurements analyzed, only length of tail exhibited enough individual variation to warrant its deletion in analysis of geographic or interspecific variation in the genus Choeroniscus. Also, because of the difficulty in consistently taking the measurement, we also suggest elimination of postorbital constriction.

Specimens of Choeroniscus intermedius were found to exhibit significant secondary sexual variation in five of the 12 measurements studied. Therefore, it is clear that males and females should be separated in analyses of variation within members of the genus. Females were found to be the larger in 10 of the 12 measurements--similar to the …


Annotated Checklist Of Mammals Of The Yucatan Peninsula, Mexico. I. Chiroptera, J. Knox Jones Jr., James Dale Smith, Hugh H. Genoways May 1973

Annotated Checklist Of Mammals Of The Yucatan Peninsula, Mexico. I. Chiroptera, J. Knox Jones Jr., James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Our field investigations on the Yucatán Peninsula were initiated in the summer of 1962 when two field parties from the Museum of Natural History at the University of Kansas visited the area. One field party consisted of W.E. Duellman and six students enrolled in a summer field course in vertebrate zoology; the other party was composed of the senior author and four students who were conducting a survey of Middle American terrestrial vertebrates and their ectoparasites. Some of the data relative to ectoparasites obtained during this study have appeared in the publications of Emerson (1971), Kohls et al. (1965), Loomis …


Checklist Of North American Mammals North Of Mexico, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways Feb 1973

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

Since the publication of "Vernacular names of North American mammals north of Mexico" by Hall et al. (1957) and its subsequent revision (Hall, 1965), systematic and other studies have contributed materially to a better understanding of the nomenclature of North American mammals. For this reason, and because of the usefulness, principally to students, of checklists that record both scientific and vernacular names, an updated listing of New World mammalian species north of Mexico is timely. As in the previous lists, a specific vernacular name applies to all populations of that species.

The present checklist includes all species of North American …


Notes On Some Mammals From Jalisco, Mexico, Hugh H. Genoways, J. Knox Jones Jr. Jan 1973

Notes On Some Mammals From Jalisco, Mexico, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The varied topography and climate of the Mexican state of Jalisco have resulted in a diverse mammalian fauna, no comprehensive account of which has been published. Significant collections of mammals from Jalisco were obtained for the Museum of Natural History, the University of Kansas, between 1949 and 1969 by field parties and individual field representatives, most notably J. R. Alcorn, R. W. Dickerman, and especially P. L. Clifton. Some of the specimens thus obtained have been recorded in systematic accounts of individual taxa or in reports on selected taxonomic groups (see for example, Choate, 1970; Genoways, 1972; Genoways and Jones, …


Two Species Of Bats New To The Fauna Of Trinidad, Hugh H. Genoways, Robert J. Baker, R. S. Loregnard Jan 1973

Two Species Of Bats New To The Fauna Of Trinidad, Hugh H. Genoways, Robert J. Baker, R. S. Loregnard

University of Nebraska State Museum: Mammalogy Papers

Goodwin and Greenhall (1961) in their monograph of the bats of Trinidad and Tobago recorded 58 species of chiropterans from the island of Trinidad. In two subsequent publications (Goodwin and Greenhall, 1962, 1964) these authors recorded Mesophylla macconnelli, Prornops nasutus, and Phylloderma stenops from Trinidad bringing the number of species known from the island to 61. In August 1967, one of us (R. J. Baker) and Larry Deaven netted bats on Trinidad in connection with ongoing studies of chiropteran karyology, and obtained two species not previously recorded.


Bats Of Jalisco, México, Larry C. Watkins, J. Knox Jones Jr., Hugh H. Genoways Dec 1972

Bats Of Jalisco, México, Larry C. Watkins, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The fauna and flora of the Mexican state of Jalisco have received the much deserved attention of a number of biologists in recent years. Nevertheless, few comprehensive accounts of the biota of this interesting and physiographically diverse area have been published. In the period from 1949 to 1969, field representatives of the Museum of Natural History at the University of Kansas collected vertebrates in Jalisco. Among the specimens obtained from the state, the mammalian fauna of which never has been treated as a unit previously, were approximately 3000 bats, which form the primary basis for this report. In addition to …


Mammals From Southwestern North Dakota, Hugh H. Genoways, J. Knox Jones Jr. Nov 1972

Mammals From Southwestern North Dakota, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The distribution of the mammals in the southwestern part of North Dakota and their ecological and taxonomic relationships have not been well documented. In addition to Vernon Bailey's (1927) survey of mammals of the state, based primarily upon field work conducted between 1912 and 1916, the only other principal studies dealing with the mammalian fauna of southwestern North Dakota were a preliminary report of the mammals of the state by Bailey et al. (1914) and the publication by J.A. Allen (1875) on mammals taken by the expedition that surveyed a route for the North Pacific Railway. Our studies, which were …


The Phyllostomatid Bat, Vampyressa Brocki, In Colombia, Robert J. Baker, Hugh H. Genoways, Alberto Cadena Apr 1972

The Phyllostomatid Bat, Vampyressa Brocki, In Colombia, Robert J. Baker, Hugh H. Genoways, Alberto Cadena

University of Nebraska State Museum: Mammalogy Papers

Between June 28 and July 1, 1969, while conducting studies on the karyotypes of phyllostomatid bats, the authors collected three specimens of Vampyressa brocki in mature tropical rainforest at Leticia, Amazonas. Colombia. Measurements and representative karyotypes are presented.


A Multivariate Analysis Of Systematic Relationships Among Populations Of The Short-Tailed Shrew (Genus Blarina) In Nebraska, Hugh H. Genoways, Jerry R. Choate Jan 1972

A Multivariate Analysis Of Systematic Relationships Among Populations Of The Short-Tailed Shrew (Genus Blarina) In Nebraska, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The genus Blarina (Mammalia: Soricidae) is represented in Nebraska by two well-differentiated, geographically exclusive phena that generally have been regarded as subspecies. Field studies conducted along their zone of contact resulted in the collection of representatives of both phena at each of five localities. Cluster analysis of distance matrix readily separated reference samples of the phena as well as test samples from near the zone of contact. A three-dimensional projection of the specimens onto their first three principal components, together with a discriminant function analysis, served further to elucidate the degree of differentiation among the phena and to confirm that …


Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways Jul 1971

Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Additional specimens of Sciurus richmondi are reported, along with comments on variation, distribution, reproduction and molt in this little known squirrel. As presently understood, S. richmondi occurs only in the Caribbean rain forests of Nicaragua. Significant secondary sexual variation in adults was found only in zygomatic breadth, in which females are the larger. Available evidence reveals that the breeding season extends at least from February to September, and suggests two seasonal molts annually.


A New Species Of Spiny Pocket Mouse (Genus Liomys) From Jalisco, Mexico, Hugh H. Genoways Jun 1971

A New Species Of Spiny Pocket Mouse (Genus Liomys) From Jalisco, Mexico, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of a systematic revision of the spiny pocket mice of the genus Liomys, a series of large, brightly colored mice from several localities in southeastern Jalisco was studied. Individuals in this series appeared to be morphologically distinct from mice typical of Liomys pictus plantinarensis Merriam. 1902, taken in the same traplines at several localities, and from specimens of Liomys irroratus jaliscensis (J. A. Allen, 1906), a taxon that also occurs in southeastern Jalisco. The current studies now have progressed to the point where the large and distinctively colored mice from Jalisco can be defined as a …


Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker Feb 1971

Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …


Harvest Mice (Genus Reithrodontomys) Of Nicaragua, J. Knox Jones Jr., Hugh H. Genoways Jul 1970

Harvest Mice (Genus Reithrodontomys) Of Nicaragua, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Harvest mice of the genus Reithrodontomys first were reported from Nicaragua by Oldfield Thomas (1907), who originally described Reithrodontomys sumichrasti modestus based on a single specimen from Jinotega. J. A. Allen (1908, 1910) recorded additional specimens of R. s. modestus, which still was the only species known from the country when A. H. Howell (1914) revised the genus Reithrodontomys. In his thorough review of Latin American harvest mice, Hooper (1952) added a second species, Reithrodontomys mexicanus lucifrons, to the Nicaraguan fauna, and Englert (1959) and Anderson and Jones (1960) recorded three additional kinds. The present report treats …


Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher Jan 1970

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …


Chiropteran Systematics, J. Knox Jones Jr., Hugh H. Genoways Jan 1970

Chiropteran Systematics, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Provides an overview of the field of chiropteran systematics in a way that will introduce the non-chiropterologist to the subject. By way of example, we have alluded to several aspects of taxonomic research at different levels in the hierarchy. Recourse to the publications cited at the appropriate places in the text will amplify our remarks and provide a solid background in the current work of the discipline.

Basically, taxonomic characters are where the taxonomist finds them; some, but not all, will prove useful also in elucidating relationships and evolutionary descent of taxa. Much remains to be done in these areas, …


Introduction Of The Red-Browed Finch To Western Australia, John L. Long Jan 1969

Introduction Of The Red-Browed Finch To Western Australia, John L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

THE Red-browed Finch (Estrilda temporalis) has been established probably since 1958 in orchard clearings in Darling Range gullies east of Perth.

Although some concern has been shown at the introduction of a new species to Western Australia, it appears to be of little economic importance.

English summary

Wieczorowski S. - The alimentary tract and the lungs parasites in hares in Białystok voivodship

87 parasitic sections were made of hares coming from Białystok voivodship territory. The investigations lead to the conclusion that the hares are 100 percent invaded by parasites. Among the roundworms of the alimentary tract, the most frequent are the following: Trichostrongylus retortaeformis (78.1 percent) and Trichocephalus sylvilagi (43 percent). Coccidiosis is also widespread; it was found in 77 percent of the investigated animals.


Notes On Spotted Skunks (Genus Spilogale) From Western Mexico, Hugh H. Genoways, J. Knox Jones Jr. Jan 1968

Notes On Spotted Skunks (Genus Spilogale) From Western Mexico, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Specimens of spotted skunks acquired from western Mexico by the Museum of Natural History at the University of Kansas in the past two decades add substantially to the knowledge of the species occurring in that region. Two specimens of the rare Spilogale pygmaea (one from Sinaloa and one from Oaxaca) are reported for the first time. Two subspecies of pygmy spotted skunk are recognized - S. p. pygmaea Thomas with type locality at Rosario, Sinaloa, and S. p. australis Hall with type locality at Acapulco, Guerrero.

The large spotted skunk, Spilogalepusorius, varies clinally in size form north (larger) to …


A New Species Of Shrew (Genus Cryptotis) From Jalisco, Mexico (Mammalia: Insectivora), Hugh H. Genoways, Jerry R. Choate Dec 1967

A New Species Of Shrew (Genus Cryptotis) From Jalisco, Mexico (Mammalia: Insectivora), Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

From July 6 to 11, 1966, vertebrates were collected on Volcan de Fuego, Jalisco, for the Museum of Natural History,the University of Kansas, by Hugh H. Genoways and Percy L. Clifton. On July 10, a shrew of the genus Cryptotis was obtained on a steep slope across the valley to the north of the active cone of the volcano. The specimen was caught in a steel trap placed in the tunnel of a pocket gopher; because the opening had not been covered after the trap was set, it could not be determined whether the shrew was using the tunnel as …

Amphibians And Reptiles Of Vigo County, Indiana, David Rubin May 1965

Amphibians And Reptiles Of Vigo County, Indiana, David Rubin

All-Inclusive List of Electronic Theses and Dissertations

Vigo County, Indiana is an extremely interesting area for herpetological studyo Its geographical location allows for the interplay of faunal elements from east, west, north, and south (Smith and minton, 1957) and its physiography permits investigation of the relations of terrain and glacial geology to herpetofaunal distribution. Blatchley (1891, 1899) published two papers on the amphibians and reptiles of the county and Allyn and Shockley (1938) reported on the county's salamandersa The present paper has the following objectives: to determine which species occur or have recently occurred in Vigo County; to determine amphibian and reptile distribution in the county; to …


Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster Jan 1965

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …


Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson Jan 1958

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson

Nebraska Game and Parks Commission: Publications

The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …


Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard Jan 1957

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …
