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

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 …

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

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, …

Results Of The Alcoa Foundation-Suriname Expeditions. V. Noteworthy Records Of Surinamese Mammals, Hugh H. Genoways, Stephen L. Williams, Jane A. Groen

University of Nebraska State Museum: Mammalogy Papers

The occurrence of seven species of mammals previously unknown in Suriname is documented. The new taxa recorded include Didelphis albiventris, Peropteryx macrotis, Lonchorhina aurita, Micronycteris hirsuta, Vampyrodes caraccioli, Furipterus horrens, and Thyroptera discifera . Additional information is provided on several species already known to occur in Suriname, including Metachirus nudicaudatus, Peronymus leucopterus, Mimon bennettii, Tonatia carrikeri, T. schulzi, Anoura geoffroyi, Choerniscus intermedius, Mesophylla macconnelli, Neaeomys guianae, Holochilus brasiliensis, and Potos fiavus.

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 …

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix F: Terrestrial Ecosystem Analysis (Supplement 2), University Of Maine At Orono, Maine, Cooperative Wildlife Research Unit, United States Army Engineer Division, New England Division

Dickey-Lincoln School Lakes Project

The overall study area encompassed the St. John River and its major tributaries; including the Little and Big Black Rivers (and their tributaries); and all lands extending 3.2 km (2 mi) beyond the maximum elevation of thv predicted impoundment of the Dickey Dam (1,560 km ). Research was concentra-ted in a portion of this area roughly bounded on the north by Chimenticook Stream, on the east by the St. John River, on the west by the United States-Canadian border, and on the south by a line drawn east-west through Seven Islands (Figure 1.0-1). Intensive marten studies were restricted to townships …

Dickey-Lincoln School Lakes Project At Dickey, Maine : Final Environmental Statement, Volume 1-4, U. S. Army Engineer Division, New England

Dickey-Lincoln School Lakes Project

The proposed Dickey-Lincoln School Lakes Project in northern Maine is a multipurpose installation on the St.John River. The combination hydroelectric power and flood control project is located in Aroostook County, Maine, near the Canadian border. The two proposed earth fill dams located at Dickey are 10,200 feet in length with a maximum height of 335 feet. They would impound 7.7 million acre feet of water at a maximum pool elevation 910 feet mean sea level. A second earth filled dam located 11 miles downstream at Lincoln School would serve as a regulatory dam. It would be 2100 feet in lenqth, …

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 …

Chesapeake Bay Bibliography - Volume V. Virginia And Maryland Waters, Marilyn Neff Loesch

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.

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.

Is Nature Our Birthright?, Nancy Heneson

Ecology Collection

It is of course impossible to escape the notion of self-interest in our relationship with nature. In fact, it is "unnatural," if one understands (and, one is forced to say nowadays, believes in) evolution. However, there is no real justification for either disguising this as stewardship or perverting it into dominionism. Every organism has an impact on the environment, and it is not only idealistic but biologically nonsensical to argue that we should leave everything alone. However, when decisions on policy are made which direct the future use of land, plants and animals, at least let the rationale not be …
