Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways
Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Introduction
Spiny pocket mice of the genus Liomys are members of the rodent family Heteromyidae and together with the genus Heteromys form the subfamily Heteromyinae. Their geographic range extends from northern Sonora, in western Mexico, and southern Texas southward to the vicinity of the Panama Canal Zone. Within this area, members of the genus occur mainly in dry to arid situations being replaced in areas of rain forest and cloud forest by members of the genus Heteromys. The vernacular name for Liomys is based on the fact that many of their hairs have been modified in the form of …

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 …

Tool-Making And Tool-Using In The Northern Blue Jay, Thony B. Jones, Alan Kamil
Papers in Behavior in Biological Sciences
Laboratory-raised Northern blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependent upon the motivational state of the jay and the presence of food pellets.

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 …

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, …
Crayfish, Leech, And Snail Control
Crayfish, Leech, And Snail Control
Great Plains Wildlife Damage Control Workshop Proceedings
We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for …

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
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 …

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 Biology And Ecology Of The Bromegrass Seed Midge In Nebraska, E. L. Nieman, G. R. Manglitz
The Biology And Ecology Of The Bromegrass Seed Midge In Nebraska, E. L. Nieman, G. R. Manglitz
Nebraska Agricultural Experiment Station: Historical Research Bulletins
These studies indicate that smooth bromegrass, Bromus inermis Leyss, is the only host of the bromegrass seed midge, Stenodiplosis bromicola Marikovskiy and Agafonova, in Nebraska. The midge did not infest two common annual brome species under field conditions. The midge has been collected from all counties surveyed in Nebraska and seems to be widely distributed throughout the midwestern states. An apparently undescribed species of Tetrastichus (Hymenoptera: Eulophiclae) was observed to parasitize all stages of the bromegrass seed midge. Parasitism rates greater than 90% were observed. The parasite larvae do not kill the midge until damage to the bromegrass floret has …
A New Species Of Menoceras From The Marsland Formation Of Nebraska, Lloyd G. Tanner
A New Species Of Menoceras From The Marsland Formation Of Nebraska, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
Further study indicates that the Menoceras remains collected from the "Bridgeport Quarries" (lower port:on or the Marsland Formation, Middle Miocene, of the Hemingford Group) are of a new species.
In 1962, these dicerathere remains were considered to be a geologic variety of Diceratherium niobrarensis (Stecher, Schultz, and Tanner). However, later (Tanner, 1969) a generic distinction was revived, separating the Menoceras Troxell from Diceratherium Marsh. Diceretherium niobrarensis was then placed in synonymy with Menoceras arikarense (Barbour).
The new species is an intermediate between Menoceras arikarense (Barbour) from the Harrison Formation and Menoceras marslandensis Tanner, from the upper portion of the Marsland …
Two Lynx-Like Cats From The Pliocene And Pleistocene, C. Bertrand Schultz, Larry D. Martin
Two Lynx-Like Cats From The Pliocene And Pleistocene, C. Bertrand Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum (1924–2023)
A new species (Lynx stouti) of small felid is described from the lower Pliocene of Colorado. This form has several characters in common with the modern Lynx and may be ancestral to that genus. A new subspecies of Lynx issiodorensis Croizet and Jobert is described as L. i. kurteni from the Mullen Assemblage, Cherry County, Nebraska. The relationships of this form to other lynxes are discussed along with the paleo-distribution of the genus.
The classification of the felinae has always been somewhat controversial, especially at the generic level. One fairly homogenous group of cats which has been separated …
Phyletic Trends In Certain Lineages Of Quaternary Mammals, C. Bertrand Schultz, Lloyd G. Tanner, Lary D. Martin
Phyletic Trends In Certain Lineages Of Quaternary Mammals, C. Bertrand Schultz, Lloyd G. Tanner, Lary D. Martin
Bulletin of the University of Nebraska State Museum (1924–2023)
Evolutionary trends in certain carnivores, rodents, bovids, and proboscideans are examined. Chronoclines are demonstrated for muskrats, beavers, mammoths, and bison. The Pliocene-Pleistocene boundary and Quaternary climatic fluctuations are also discussed.
The University of Nebraska State Museum contains a large stratigraphically controlled collection of Pleistocene animals. This collection provides a unique opportunity for the study of phyletic trends in certain lineages of mammals. Although a few phylogenetic lineages have been proposed (Schultz and Frankforter, 1946; Hibbard, et al., 1965), this has not been done for the vast majority of Pleistocene mammals. However, there is much more data available than this would …

Three-Configuration Matching-To-Sample In The Pigeon, Alan Kamil, Robert A. Sacks
Papers in Behavior in Biological Sciences
Pigeons were trained on a zero-delay matching-to-sample procedure during which only three of the four possible stimulus configurations were presented. Subsequently, all birds were exposed to all four configurations as a transfer test. A high degree of negative transfer from the three training configurations was obtained in Experiment 1. The results of Experiment 2 indicated that three-configuration training produced differential position-preference effects. During the transfer test, responding after one sample stimulus was apparently based on position, while responding after the other sample was based on color.
The Microtine Rodents Of The Mullen Assemblage From The Pleistocene Of North Central Nebraska, Larry D. Martin
The Microtine Rodents Of The Mullen Assemblage From The Pleistocene Of North Central Nebraska, Larry D. Martin
Bulletin of the University of Nebraska State Museum (1924–2023)
The University of Nebraska State Museum has had an active collecting program in Hooker and Cherry counties, Nebraska, since the 1930's. The following University of Nebraska State Museum collecting localities have been extensively excavated: Cr-10, Cr-102, Cr-11, Ho-101, Ho-102, and Ho-103. These localities have produced a large vertebrate fauna described by Jakway as the Mullen Local Fauna which he considered for the most part to be Early lllinoian. Further study of this local fauna now demonstrates that assemblage does include Early as well as Middle Pleistocene animals. The purpose of this paper is to report on the evidence regarding the …

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