Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways
Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for southwestern populations, and the name Blarina carolinensis is here restricted to short-tailed shrews in the southeastern United States.
Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways
Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
The Texas pocket gopher (Geomys personarus), which occupies a range in southern Texas and extreme northeastern Tamaulipas, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, secondary sexual, individual, and geographic variation. Significant differences were found among the three age classes and between the sexes for 12 of 13 cranial measurements. Males displayed higher individual variation than females. Distributions of the six previously recognized subspecies (fallax, fuscus, maritimus, megapotamus, personatus, and streckeri) were examined. An additional subspecies is recognized and described. Of the seven subspecies of …
Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways
Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla from Phyllonycteris are in the general range of values that characterize congeneric species of mammals. Immunological distance values for the species Glossophaga soricina, Monophyllus redmani, Anoura caudifer, Leptonycteris sanborni, Choeroniscus minor, and Hylonycteris underuoodi indicate that these taxa are approximately equidistant from the Brachyphyllinae. Immunological comparisons of Glossophaga and Monophyllus to Anoura, Leptonycteris, Choeroniscus, …
Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker
Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
Mice of the genus Peromyscus are found in virtually every habitat type in Guadalupe Mountains National Park in West Texas. Because of their abundance and wide distribution, they comprise an important component of the park's ecosystem. The first known specimens of Peromyscus from the area now included in the park were collected by Vernon Bailey in 1901 (Bailey, 1905). He collected specimens of Peromyscus boyIii in Dog and McKittrick canyons. Davis (1940) collected P. leucopus at Frijole in 1938 and P. boylii in The Bowl in 1938 and 1939. Davis and Robertson (1944) reported collecting P. pectoralis from along Bell …
Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech
Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech
USGS Northern Prairie Wildlife Research Center
The gray wolf Canis lupus occupies only about 1 percent of its former range in the lower 48 states (Mech 1974a). Most of the range is in northern Minnesota, where the resident population is classified as "threatened" by the U.S. Department of the Interior. Wolves have been and will continue to be the subject of considerable controversy in Minnesota.
The first scientific study of wolves in Minnesota was conducted by Olson (1938a,b). That and all subsequent re- search was in the Superior National Forest (SNF) of northeastern Minnesota even though wolves inhabit approximately the northern third of the state. Consequently, …

Deer Social Organization And Wolf Predation In Northeastern Minnesota, Michael E. Nelson, L. David Mech
Deer Social Organization And Wolf Predation In Northeastern Minnesota, Michael E. Nelson, L. David Mech
USGS Northern Prairie Wildlife Research Center
The white-tailed deer Odocoileus virginianus has been subject to intensive research and management, yet we are just beginning to understand its social organization. Little is known about home range formation, migration, social bonds, and traditions in this deer, what functions they serve, and what selective forces have affected them.
Predation by wolves Canis lupus, in particular, has not been examined as a factor in deer evolution, yet the intimate interactions between deer and wolf through the millennia no doubt strongly influenced major morphological and behavioral adaptations in both species. It is a reasonable assumption that wolf predation has been …

Observations On Bats From Trinidad, With A Checklist Of Species Occurring On The Island, Catherine H. Carter, Hugh H. Genoways, Robert S. Loregnard, Robert J. Baker
Observations On Bats From Trinidad, With A Checklist Of Species Occurring On The Island, Catherine H. Carter, Hugh H. Genoways, Robert S. Loregnard, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
In their comprehensive treatment of the bats of Trinidad, Goodwin and Greenhall (1961) reported 58 species from the island. Subsequent authors (Goodwin and Greenhall, 1962, 1964; Genoways et al., 1973a; LaVal, 1973a, 1973b) have added some species to the list and changed the status of others so that the known chiropteran fauna of Trinidad now comprises 64 species: five emballonurids, one noctilionid, four mormoopids, 36 phyllostomids (see Handley, 1980, for family-group names), one natalid, one furipterid, one thyropterid, seven vespertilionids, and eight molossids. Among the phyllostomids, the subfamilies Phyllostominae (15) and Stenodermatinae (14) are the best represented, whereas only a …
Spatial Memory And The Performance Of Rats And Pigeons In The Radial-Arm Maze, Alan B. Bond, Robert G. Cook, Marvin R. Lamb
Spatial Memory And The Performance Of Rats And Pigeons In The Radial-Arm Maze, Alan B. Bond, Robert G. Cook, Marvin R. Lamb
Papers in Behavior in Biological Sciences
The resource-distribution hypothesis states that the ability of an animal to remember the spatial location of past events is related to the typical distribution of food resources for the species. It appears to predict that Norway rats would perform better than domestic pigeons in tasks requiring spatial event memory. Pigeons, tested in an eight-arm radial maze, exhibited no more than half of the memory capacity observed in rats in the same apparatus and may not have used spatial memory at all. The results were interpreted as supporting the hypothesis.

Die Erforschung Der Herpetofauna Der Mongolischen Volksrepublik: Situation Und Perspektiven, Günther Peters
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
First paragraph:
Die Landschaften der Mongolei sind arm an Reptilien- und Amphibienarten. Dieser Umstand mag die Frage aufwerfen, ob herpetologische Untersuchungen in Beschränkung auf das Territorium der MVR eine nennenswerte Perspektive haben könnten, nachdem Artenspektrum und Verbteitung der Species annähernd vollständig erkundet sind. Ein Herpetologe wird zweifellos für seine Arbeit auch in diesem Land eine Zukunft sehen, doch muß wohl von vornherein eingestanden werden, daß das Volumen der Probleme dieses Faches hinter denen der übrigen Disziplinen der Vertebratenzoologie und der Entomologie in einem bescheidenerem Rahmen verbleibt. Dies gilt sowohl im rein wissenschaftlichen als erst recht auch im angewandten Bereich ihrer …
Giving-Up As A Poisson Process: The Departure Decision Of The Green Lacewing, Alan B. Bond
Giving-Up As A Poisson Process: The Departure Decision Of The Green Lacewing, Alan B. Bond
Alan Bond Publications
Predators that forage for aggregated prey appear to require a decision rule for determining the point at which to discontinue their search in a given prey patch and move on to another. Although the optimum rule depends heavily on features of the searching behavior of the predator and the distribution of the prey (Oaten 1977), most previous authors have assumed that the decision must involve an assessment of the capture rate within a patch and a comparison with the mean capture rate in the environment as a whole (Krebs 1978). When the perceived quality of the given patch becomes significantly …
Cover Of Plants With Extrafloral Nectaries At Four Northern California Sites, Kathleen H. Keeler
Cover Of Plants With Extrafloral Nectaries At Four Northern California Sites, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Percent cover of plants with extrafloral nectaries was investigated in three California habitats with the same physiognomy as habitats previously studied in Nebraska (perennial native grassland, riparian forest, deciduous forest). In contrast to Nebraska where cover of plants with extrafloral nectaries reached 14 percent, no plants with extrafloral nectaries were found in any California transect. Chaparral was also studied; no plants with extrafloral nectaries were found.
