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.

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 …

Variation And Ecology In A Local Population Of The Vesper Mouse (Nyctomys Sumichrasti), Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Vesper mice of the genus Nyctomys are relatively rare, arboreal rodents restricted to Middle America (eastern Panama to southern Mexico). Little is known concerning the biology of these secretive animals. Studies of variation of the one species, Nyctomys sumichrasti, have been limited to descriptions of new taxa (for example, see Goldman, 1916, 1937, and Laurie, 1953) and ecological observations have been confined to faunal accounts of political units (Goodwin, 1934; Hall and Dalquest, 1963) or were made coincidental to studies of other species (Lawlor, 1969; Fleming, 1970). Birkenholz and Wirtz (1965) recorded observations on the behavior, reproduction, and early …

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 …

Second Specimen Of Oryzomys Dimidiatus, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The species Oryzomys dimidiatus was originally named and described by Thomas (Annals of the Museum of Natural History, series 7, 15: 584-591, 1905) as a member of the genus Nectomys on the basis of a single specimen from the Rio Escondido, 7 miles below Rama, Nicaragua (approximately 1 km. S and 8½ km. E Ranla, 20 m, Zelaya), obtained by W. G. Palmer on November 5, 1904. Although there has been speculation on the relationships of this taxon (currently regarded as the only member of the subgenus Micronectmays, genus Oryzomys--see Hershkovitz, Journal of Mammalogy, 51: 789-794, 1970, …

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

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 …

Systematics Of Southern Banner-Tailed Kangaroo Rats Of The Dipodomys Phillipsii Group, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.

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 …

Bacula Of Some Neotropical Bats, Randall E. Brown, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Neotropical bats representing 56 species of five families were examined for presence or absence of a baculum. Members of the families Noctilionidae and Phyllostomatidae (sensu lato) have no os penis, but the bone was found in all species studied of Emballonuridae, Natalidae, and Vespertilionidae. The bacula of seven emballonurids, one natalid, and seven vespertilionids are briefly described and figured.

Additional Notes An Some Mammals From Eastern Nebraska, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Field studies concerned primarily with distribution of the short-tailed shrew, Blarina brevicauda, in eastern Nebraska have resulted in noteworthy records of several other species of small mammals. These field studies, which were supported by a grant from the Kansas Academy of Science, entailed extensive trapping of prairie habitats in Cass County, approximately 15 miles west of the Missouri River. In addition to the species discussed below, specimens of Reithrodontomys megalotis, Peromyscus maniculatus, P. leucopus, and Mus musculus were obtained at several localities. All catalogue numbers in the following accounts refer to specimens deposited in the Museum of Natural …

Taxonomy Of The Neotoma Albigula-Group Of Woodrats In Central Mexico, E. Raymond Hall, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Study of specimens collected from critical localities since 1944 reveals that: Neotoma montezumae and N. leucodon zacatecae are indistinguishable from earlier named taxa; N. latifrons is a subspecies of an earlier named taxon; and N. palatina, previously known from only one specimen and thought by some mammalogists to be merely an aberrant individual of Neotoma albigula, is a species distinct from N. albigula as Goldman tentatively decided when he named it 64 years ago. In the narial passage, the partition formed by the vomer that extends well behind the hard palate as a sword-like projection is present in …

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 …

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins

University of Nebraska State Museum: Mammalogy Papers

Distribution and variation in Mexican representatives of the vespertilionid bat genus Myotis have not been well documented. The most complete modern systematic treatment of these bats is that of Miller and Allen (1928), although these authors examined relatively few specimens and some of their taxonomic conclusions have been modified by more recent studies (see especially Findley, 1960; Findley and Jones, 1967; Genoways and Jones, 1969). In the past two decades, field representatives of the Museum of Natural History at The University of Kansas have obtained large collections of mammals in western Mexico, principally in the states of Jalisco and Sinaloa. …

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

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, …

Notes On Pocket Gophers From Jalisco, Mexico, With Descriptions Of Two New Subspecies, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Systematic, distributional, and ecological data are provided for seven taxa, two described as new, of three species of the pocket gopher genus Pappogeomys in the Mexican state of Jalisco. The first Jaliscan record of Orthogeomys grandis also is reported and several instances of sympatric occurrence of pocket gophers are documented.
