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.


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 …

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.


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 …

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 …

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk Jun 1940

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

The Buffy Plains Pocket-mouse (Perognathus flavescens flavescens) is a typical mammal of the Sandhill Region of Nebraska. Its home, like that of other species of pocket-mice, is a series of burrows in the ground, consisting of several entrance holes leading to the main 'burrow, in which is located the nest and the food storage chambers. In the Nebraska sandhills its burrows and nests are commonly placed beneath clumps of Spanish Bayonet or Prickly Pear Cactus, and the entrance holes usually are so distributed as to open from under the plant in all directions.

The writer had hoped to …


A Study Of Subspecific Variation In The Yellow Pocket-Gopher (Geomys Lutescens) In Nebraska, And Of The Geographical And Ecological Distribution Of The Variants, Myron H. Swenk Feb 1940

A Study Of Subspecific Variation In The Yellow Pocket-Gopher (Geomys Lutescens) In Nebraska, And Of The Geographical And Ecological Distribution Of The Variants, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

The Yellow Pocket-Gopher (Geomys lutescens) was described by Merriam (14) in 1890, as a paler and smaller subspecies of Geomys bursarius, based on "numerous specimens received from the Sand Hills of western Nebraska", and especially upon an adult Cjl type specimen (No. 23595, U. S. N. M.) collected in the sandhills along Birdwood Creek, Lincoln County, Nebraska, May 27, 1889, by A. B. Baker. Although even as late as 1931 Scheffer (17) classified Geomys lutescens as a subspecies of G. bursarius, it is without doubt specifically distinct from G. bursarius. In all of its variations …


A Study Of Local Size Variations In The Prairie Pocket-Gopher (Geomys Bursarius), With Description Of A New Subspecies From Nebraska, Myron H. Swenk Dec 1939

A Study Of Local Size Variations In The Prairie Pocket-Gopher (Geomys Bursarius), With Description Of A New Subspecies From Nebraska, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

Beginning in the fall of 1913, the writer has continuously been interested in accumulating accurate body measurements, taken in the flesh, of Nebraska pocket-gophers. As a result quite an assemblage of such data has been secured. In the case of Geomys bursarius, the bulk of these data relates to specimens trapped in the vicinity of Lincoln, Lancaster County, involving to date 48 adult and 38 immature males and 50 adult and 65 immature females. Recently these measurements have been tabulated and compared with such measurements of the species as have been recorded in the literature from other parts of …


The Tapeworms Of The Rhinoceroses, A Study Based On Material From The Belgian Congo, Horace W. Stunkard Jan 1926

The Tapeworms Of The Rhinoceroses, A Study Based On Material From The Belgian Congo, Horace W. Stunkard

Harold W. Manter Laboratory of Parasitology: Library Materials

During the course of my study on the parasitic worms collected by the Lang-Chapin expedition of the American Museum to the Belgian Congo, I have had the good fortune to examine abundant material of Plagiotaenia gigantea (Peters). This interesting species, the first reported from the rhinoceros, has been confused with other cestodes from rhinoceros hosts, has been assigned to no less than three different genera in addition to the genus Taenia, to which it was originally referred, and has been the source of much discussion and difference of opinion during the past seventy years. A review of the literature …


Trematodes From The Rat, Horace Wesley Stunkard, Chilson B. Haviland Jan 1924

Trematodes From The Rat, Horace Wesley Stunkard, Chilson B. Haviland

Harold W. Manter Laboratory of Parasitology: Library Materials

Occasional examinations of rats for animal parasites have been carried on for over a hundred years. Later, knowledge of the importance of rats as reservoirs of infection and as agents in the transfer of parasitic diseases has led to the regular and careful examination of large numbers in various parts of the world. Among the more recent publications dealing with the parasites of rats may be mentioned Shipley (1908), Moll (1917), Chandler (1921), Balfour (1922), Baylis (1922), Stevenson (1922), Hegner (1923), and Lavier (1924). Notwithstanding the many investigations, only a single trematode parasite has previously been discovered and concerning it …
