Homing And Ecology In The Southern Flying Squirrel, Glaucomys Volans In Southeastern Virginia, Sherrie Lynn Sawyer

Biological Sciences Theses & Dissertations

The purpose of this study was to determine whether homing occurred in the southern flying squirrel, Glauaomys volans, and if so, the greatest homing distance. Information on the squirrel's ecology, reproductive biology and use of artificial nest boxes was also obtained. The study was conducted from November 1978 through March 1981, using nest boxes placed in a deciduous forest in southeastern Virginia.

For the homing experiments, twenty squirrels were released a total of 29 times along three lines at distances of 250 m to 1.6 km from the homesites. Squirrels were found to home successfully up to 1,000 m.

Abundance And Seasonal Occurrence Of Psorophora Columbiae In A Northeast Arkansas Ricefield Community, Larry A. Olson, Julia A. Huggins

Journal of the Arkansas Academy of Science

Increased population levels of the dark ricefield mosquito, Psorophora columbiae (Dyar and Knab), have been shown to be associated with rice cultivation in Arkansas and several other states. Four standard New Jersey light traps were operated daily between May 30 and October 2 of 1981 and 1982 to determine the relative abundance and seasonal occurrence of this species in NE Arkansas. The effect of trap distance from nearby rice on the number of adult P. columbiae collected was assessed by comparing weekly totals from 2 traps located within 0.9 km of rice fields with totals from 2 traps situated beyond …

Gastrointestinal Helminths Of The Cougar, Felis Concolor L., In Northeastern Oregon, Robert L. Rausch, C. Maser, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths of nine species were identified from 39 cougars obtained in northeastern Oregon (Walbowa, Baker, and Union counties), viz., Taenia omissa Lühe, 1910 (100%); T. ovis krabbei Moniez, 1879 (61%); T. hydatigena Pallas, 1776 (10%); Mesocestoides lineatus (Goeze, 1782) (5%); Toxascaris leonina (von Linstow, 1902) (69%); Toxocara cati (Schrank, 1788) (15%); Physaloptera praeputialis von Linstow, 1889 (13%); Pterygodermatites affinis (Jagerskiold, 1904) (ca. 2%); and Trichinella sp. (larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are …

Karyotypic Relationships Within The Short-Tailed Shrews, Genus Blarina, Sarah B. George, Hugh H. Genoways, Jerry R. Choate, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

Short-tailed shrews of the genus Blarina exhibit considerable geographic variation in both diploid number and fundamental number. Four chromosomal groups are recognized within the genus: Blarina brevicauda, FN = 48; 2N = 50, 49, or 48; B. carolinensis, FN = 45 or 44; 2N = 46, 39, 38, or 37; B. c. peninsulae, FN = 52; 2N = 52, 51, or 50; B. hylophaga, FN = 62, 61, or 60; 2N = 52. B. c. peninsulae also may be a distinct species, but exact determination must await location and analysis of a zone of contact with …

Morphometric And Geographic Relationships Of Short-Tailed Shrews (Genus Blarina) In Kansas, Iowa, And Missouri, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Shrews of the genus Blarina from Iowa, Kansas, and Missouri were studied morphometrically and karyologically. The ranges of two species, B. brevicauda and B. hylophaga, overlap in a broad zone across southern Iowa and northern Missouri. Morphometric analyses revealed an unexpectedly large amount of cranial variation in B. brevicauda, and confirmed the presence of that species in the Kansas River Valley of northeastern Kansas. Considerable mensural overlap was found in geographic areas in which B. hylophaga and B. brevicauda are sympatric, evincing the need for further karyotypic and morphometric studies in those areas. No formal taxonomic changes are …

The Suriname Small Mammal Survey: A Case Study Of The Cooperation Between Research And National Conservation Needs, Hugh H. Genoways, Henry A. Reichart, Stephen L. Williams

University of Nebraska State Museum: Mammalogy Papers

A cooperative program between the Foundation for Nature Preservation in Suriname and the Carnegie Museum of Natural History to survey the small mammals of Suriname is reviewed. The program has proven to be mutually beneficial and it is presented as a model for development of similar programs in the future. The technical assistance requested by the Foundation for Nature Preservation in Suriname concerned the distribution and natural history of small mammals, especially those occurring in the Nature Parks and Reserves. The Government of Suriname has established an excellent system of Reserves and Parks throughout the country. They are trying to …

Aquatic Macroinvertebrates Of Three Acid Bogs On Crowley's Ridge In Northeast Arkansas, Jerry L. Farris, George L. Harp

Journal of the Arkansas Academy of Science

Qualities and quantities of parameters composing the bog systems in Northeast Arkansas are not entirely reflective of those defining bogs of the northern United States. While pH is restricting to the organisms of each bog studied (4.8-6.9), the major limiting factor is the amount of available water. Three acidophilic bogs with shallow water depths (2-30 cm) yielded a total of 75 aquatic macroinvertebrate taxa. The bog with greatest surface area supported 67 taxa and a mean numerical standing crop of 14 organisms/2 hr sampling period. The bog with the smallest surface area had 13 taxa and a mean standing crop …

Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton

Journal of the Arkansas Academy of Science

Soil traversing arthropod populations were sampled by pitfall traps in sunflower (Helianthus spp.) and three adjacent habitats during the months of July, August and September of 1980 and May, June, July and August of 1981. In1980, four varieties of sunflower (Ellar, Hybrid 670, 891 and S-345) were planted. A single variety of sunflower (Ellar) was planted in1981. The three adjacent habitats in both 1980 and 1981 were a pine stand, grass border and fence row. Of 1,748 specimens collected in 1980, 17 orders and 48 families were represented. Four orders comprised 78% of the total catch: Hymenoptera (45%), Acari (17%), …

Invertebrate Fauna Of Devils Den, A Sandstone Cave In Northwestern Arkansas, Stewart B. Peck, James H. Peck

Journal of the Arkansas Academy of Science

The same invertebrate fauna of 17 species was found in Devils Den Cave, Washington County, Arkansas, in 1969 and 1979. The fauna consists of 1 trogloxene, 14 troglophiles, and 2 troglobites, a spider, Porrhomma cavernicolum, and a collembolan, Pseudosinella dubia. Devils Den Cave has a well developed cavernicolous fauna, although it is in sandstone which generally supports a poor cave adapted fauna. The troglobites probably evolved in the vicinity of northwestern Arkansas in limestone caves or in deep forest soils of the Ozark region. They then dispersed overland, perhaps as recently as the late Wisconsinan, to occupy this sandstone cave.

Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche

Journal of the Arkansas Academy of Science

A diverse warmwater fish community has persisted in the Lake Greeson tailwater, despite hydropower releases of cold hypolimnetic water. Forty-eight species of fish were collected by electrofishing in the upper 16.1 km of the tailwater. Hydropower releases have reduced the abundance of some of the warmwater sport fish in the upper tailwater, and their populations are probably maintained in part by recruitment from downstream. Angling effort has been diverted from the warmwater sport fish populations to a put-and-take trout fishery.

River Otter In Arkansas: Ii. Indications Of A Beaver-Facilitated Commensal Relationship, C. Renn Tumlison, Mark R. Karnes, Anthony W. King

Journal of the Arkansas Academy of Science

Dam building activities of beaver (Castor canadensis) create ponds that apparently augment habitat available to otter (Lutra canadensis). This paper considers possible effects of beaver activity and pond formation on distribution and populations of otter in Arkansas. Literature synthesis and analysis of harvest records were used to investigate the suspected relationship.

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 …

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.

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 …

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 …

Karyology And Morphometrics Of Three Species Of Akodon (Mammalia: Muridae) From Northwestern Argentina, Rubén M. Barquez, Daniel F. Williams, Michael A. Mares, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Chromosomal and morphometric studies were conducted on a sample from an assemblage of Akodon spp. occurring in various patterns of sympatry from the provinces of Catamarca, Jujuy, Salta, and Tucumán, Argentina. Results showed three distinct morphometric groups based upon size. Size also varied with age, but there were no significant differences in measurements of males and females. The three morphometric groups have distinct karyotypes. Akodon caenosus Thomas is the smallest of the three, and has a karyotype of 2n = 34, FN = 40. A. boliviensis tucumanensis J. A. Allen is intermediate in size and has 2n = 40, FN …

An Evaluation Of Small Rodent Populations In Four Dismal Swamp Plant Communities, Fiona Elizabeth Breidling

Biological Sciences Theses & Dissertations

Diversity and density of small rodents in the Dismal Swamp are believed to be low. Reasons for this may be excessive predation, heavy interspecific pressure from larger rodents, lack of suitable habitat, low food availability or flooding.

Rodent populations were evaluated using live-traps and pitfall traps in four different Dismal Swamp plant communities. Habitat was compared on the basis of phytomass studies previously reported. Flood levels were recorded during live-trapping sessions. Mast from trees was collected in modified mast collectors, and fed to Peromyscus leucopus in the laboratory. Mast was analyzed for caloric value and nutrient content.

Only two …

The Section Of Mammals Of Carnegie Museum Of Natural History, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

The Section of Mammals at Carnegie Museum of Natural History is responsible for the care of the collections of Recent mammals, and research on these collections. "Recent mammals?!" The capitalized word "Recent" refers to the geological time period since the last ice age (about 10,000 years ago) until the present time. Mammals are that group of animals characterized by the presence of hair at least during some time of their lives, warm blood, and the production of milk. Therefore, our work really involves living mammals with which everyone is familiar; however, our work also does include study of such recently …

Demographic And Reproductive Parameters Of The Yellow-Cheeked Pocket Gopher (Pappogeomys Castanops), Michael J. Smolen, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A population of Pappogeomys castanops simulans was live-trapped on a 3.5-ha study area in Lubbock, Texas, from September 1971 to September 1973. Seasonal and annual differences in population size were observed, with the population fluctuating between 20 and 25 gophers. Female reproductive activity began in January and continued until October, with an obvious period of recruitment lacking; however, a peak was observed in March and April. Females produced as many as three litters per reproductive season. Females born early in the year were sexually mature within the reproductive season of their birth. Females had an average survival rate of 56 …

Notes On The Natural History Of Bats From Badlands National Monument, South Dakota, John P. Farney, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Little has been published on the mammalian fauna of Badlands National Monument, a unique ecological area that encompasses parts of Jackson and Pennington counties in South Dakota. By way of example, although five species of bats are herein recorded from the Monument, only one has been reported previously - see Jones and Choate (1978), who listed two specimens of Myotis thysanodes pahasapensis from the Cliff Shelf area. Jones and Genoways (1976b), however, did report several other species from badland areas not far distant from the boundary of the Monument.

In 1970, under sponsorship of the Badlands Natural History Association and …
