Raising Wood Ducks, Richard L. Nelson

Nebraska Game and Parks Commission: Publications

Numbered among Nature's most colorful creatures, wood ducks willingly accept a helping hand from man in establishing new homes. These birds adapt well to suitable habitat, and you can play an important part in bringing the wood duck to locations where they do not now nest. For groups or individuals who are willing to expend the effort necessary to undertake a wood duck restoration project anti see it to completion, it is an exceptional gift from today's generation to those of decades and centuries to come. Many areas in Nebraska provide suitable wood duck habitat, but do not have a …

Federal And State Regulations Pertaining To Systematic Collections. I. A Case Of Inadvertent Violation Of Federal Regulations, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

On 25 April 1975, at the twenty-second annual meeting of the Southwestern Association of Naturalists (SWAN), at the University of Oklahoma Biological Station, President Keith A. Arnold appointed Jerry Choate to investigate current regulations pertaining to collection and transport of scientific specimens in the region of representation (including Mexico) or SWAN. This charge involves both Federal and State laws, several of which are undergoing change and many of which doubtlessly are not familiar to the membership of SWAN. In order that SWAN members might be made aware of these regulations and not unwittingly commit violations, it was decided that SWANEWS …

Bats Of Margarita Island, Venezuela, With Zoogeographic Comments, James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Sixteen species of bats are reported from Margarita Island, Nueva Esparta, Venezuela. These include two species of emballonurids, one noctilionid, two mormoopids, nine phyllostomatids, one vespertilionid, and one molossid. Accounts including natural history and taxonomic comments are given for each species. The chiropteran fauna of Margarita Island is compared with the bat faunas of the adjacent Venezuelan mainland and islands off the northern coast of South America, including Trinidad and other Antillean islands. It is concluded that the chiropteran fauna of Margarita Island represents an attenuated mainland fauna.

Neolabidophorus Yucatanensis Gen. Et Sp. N. And A New Record For Dermacarus Ornatus Fain, 1967 (Acarina: Glycyphagidae) From Heteromys Gaumeri Allen And Chapman, 1897, Gaumer's Spiny Pocket Mouse (Rodentia: Heteromyidae), Danny B. Pence, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Two species of hypopial nyrnphs of mites of the family Glycyphagidae were recovered from Heteromys gaumeri from Yucatan, Mexico. Numerous specimens of a hypopus identified as Dermacarus ornatus. Fain were recovered from the hair and skin. A single specimen of an endoparasitic hypopus identified as a new genus and species, Neolabidophorus yucatanensis, was recovered from the hair follicles. The new genus differs from similar forms of the subfamily Metalabidophorinae in having a rudimentary clasper organ represented by a median sclerite behind legs IV without external serrated claspers, structure and slightly dorsal position of the tarsal solenidia on legs …

Annotated Checklist Of Mammals Of The Yucatan Peninsula, Mexico. Iii. Marsupialia, Insectivora, Primates, Edentata, Lagomorpha, J. Knox Jones, Hugh H. Genoways, James D. Smith

University of Nebraska State Museum: Mammalogy Papers

This is the third in a series of papers detailing the distribution of mammalian species occurring on the Yucatan Peninsula of Mexico. The present paper deals with 12 native species belonging to the following orders: Marsupialia, six; Insectivora, one; Primates, two; Edentata, two; Lagomorpha, one. None of these species is endemic to the peninsula, although it constitutes the major part of the geographic range of Alouatta pigra. Endemic subspecies include Didelphis virginiana yucatanensis, Marmosa mexicana mayensis, and Sylvilagus floridanus yucatanicus.

Annotated Checklist Of Mammals Of The Yucatán Peninsula, México. Ii. Rodentia, J. Knox Jones Jr., Hugh H. Genoways, Timothy E. Lawlor

University of Nebraska State Museum: Mammalogy Papers

The Yucatán Peninsula, as encompassed in this series of papers, includes the Mexican states of Campeche and Yucatán, and the Federal Territory of Quintana Roo. This region is a low-lying plain that rises gently in elevation from north to south. It is surrounded on three sides by water and bounded on the south by British Honduras (i.e. Belize), Guatemala, and the Mexican state of Tabasco. The vegetation of the peninsula increases in height from north to south and from the coast inland. Generally, forest to the north is xerophilic, but that of the southern part of the peninsula is tall, …

Oregon's Nutria Problem, Lee W. Kuhn, E. Paul Peloquin

Vertebrate Pest Conference Proceedings: 6th (1974)

The nutria or coypu, Myocastor coypus, is a large semi-aquatic rodent that superficially resembles an overgrown muskrat or a stunted beaver. They were introduced into Oregon from about 1930 to the 1950s. At one time Oregon had more than 600 fur farmers raising these animals for fur; now there are none. Some animals escaped and many others were released into the wild when it became apparent that pelt values were nonexistent and production costs greatly exceeded profits. Being prolific and quite mobile the nutria quickly spread through much of western Oregon. By the 1960s damage to agricultural crops was …

A New Vespertilionine Bat From The Barstovian Deposits Of Montana, John F. Sutton, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

During the 1972 field season, a small collection of micromammals was obtained from the Anceney Local Fauna located 13 miles west of Bozeman, Gallatin County, Montana. The fauna is Barstovian in age (Upper Miocene) and is preserved in an ash-filled channel deposit in the Madison Valley Formation (Dorr, 1956). A single partial jaw of a chiropteran was recovered along with numerous bones and teeth of other mammals, birds, amphibians, and reptiles. The jaw is complete from incisors back to the level of the m2. Examination of the jaw and comparisons with Recent and fossil chiropterans has convinced us that it …

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 …

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

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

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.

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, …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

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.
