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, …


Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey Jul 1969

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.


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.

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 …

Endangered And Threatened Wildlife And Plants: Proposed Endangered Status For The American Burying Beetle Oct 1966

Endangered And Threatened Wildlife And Plants: Proposed Endangered Status For The American Burying Beetle

Endangered Species Bulletin

The Service proposes to determine endangered status for the American burying beetle (Nicrophorus americanus) and thereby provide the species protection under the Endangered Species Act of 1973, as amended. Once widely distributed throughout eastern North America, this species has disappeared from most of its former range. Two known populations currently exist, one in eastern Oklahoma and the other on an island off the coast of New England. Despite extensive efforts to locate additional populations, only two specimens have been found elsewhere in more than 10 years. The cause of the species’ decline is unknown. Critical habitat is not …
