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 …

Evolutionary Origin Of Eptesicus Lynni, Michael L. Arnold, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Currently, three species of bats of the genus Eptesicus (fuscus, guadeloupensis, and lynni) are recognized as occurring on islands in the Antilles. Of these, E. fuscus and E. guadeloupensis are believed to belong to the fuscus-group of the genus (Davis, 1966; Genoways and Baker, 1975). However, the status and relationships of E. lynni are unclear. Shamel (1945) described lynni as a member of the brasiliensis-group. On the other hand, Sanbom (1941) considered three earlier specimens of lynni as members of the subspecies E. fuscus hispaniolae (we have examined the Sanbom specimens and they are referable to …

Relationship Between Relative Brain Size And Climbing Ability In Peromyscus, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Eisenberg and Wilson (Evolution, 32:740-751, 1978) have documented an interesting relationship between the relative brain size of bats and the complexity of the habitat in which they forage. They found that bats that fly and forage through foliage have larger brains relative to their body size than those that forage in open air. Their explanation was that bats in the complex habitat must process more complex sonic information to navigate through the foliage. In order to do this a larger brain is required.

The Peromyscus of North America may offer a similar paradigm as far as habitat complexity …

1979 Christmas Count

Nebraska Bird Review

Ninety-nine species (four less than last year) were reported in the 1979 Christmas Count, and one species was reported present but not seen on the count. (There was no such species reported last year.) This drop was in spite of one more count - from Kearney - this year. The number of additional races reported - three - was the same as last year. The individual count this year was 188,102 compared to 90,000 last year, and most of the increase was due to the Snow Goose and Mallard counts along the Missouri River, which in turn was due to …

Twenty-One Years Of Say's Phoebes, Doris Gates

Nebraska Bird Review

Mr. and Mrs. Carl Lindeken live 10.5 miles northeast of Chadron, Nebraska, in a home with a big picture window over the kitchen sink, a window that faces the Sheridan Gates, a formation which is in Sheridan County across the Dawes County line. Outside the window is a small platform on which Say's Phoebes have nested for many years.

The first year the Lindekens were aware of Say's Phoebes was in 1958 when a pair nested in the garage, a building which is attached to the house. The birds were "messy" but they were allowed to remain through the summer. …

Observations Of Late Fall Migratory Sandhill Cranes, Platte River, Nebraska, John G. Aronson

Nebraska Bird Review

Observations of migratory Sandhill Cranes (Grus canadensis) were made on the Platte River near Kearney, Nebraska. On 26 November 1978, night roosting in the Platte River occurred on thin ice (less than 2 cm) in open areas which were protected by riparian vegetation from cold north winds (35-40 km/hr-NNW, -10°C). Roosting Cranes were spaced very closely (less than 0.5 m) during evening and early morning hours, with increased spacing (about 1.0 m) occurring during late morning. A diagram of the roost area was prepared. The roost was located near the northern river bank in a river stretch characterized …

A Ground Dove At Desoto Nwr, Loren Padelford, Babs Padelford

Nebraska Bird Review

A Ground Dove was sighted at DeSoto National Wildlife Refuge on 18 November 1979, for about ten minutes around 11 AM, in the hedgerows opposite the entrance to the nature trail, south of the swimming beach.

It was a small dove, only slightly longer but chunkier than Tree Sparrows sitting in the same small tree. There was gray scalloping on the head and breast, the eye was dark, the beak light colored at the base, with the rest appearing dark. The wing was grayish with black speckling from shoulder to tip. We noticed a short tail when the bird was …

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 …

Age Study Of Minnesota Red Fox Using Cementum Annulae Counts And Tooth X-Rays, Dennis E. Simon, Merrill J. Frydendall

Journal of the Minnesota Academy of Science

A prerequisite to the proper management of an animal species is understanding of its population dynamics. Attempting this, the age structure of 297 red fox trapped or shot in southern Minnesota was investigated, using the techniques of tooth sectioning and x-ray. Results from two seasons (1977 and 1978) were similar, with 76.8 percent of the harvested population being juveniles (78.4 percent, 1977 and 74.6 percent, 1978), whereas only 0 .6 percent of the total were in the 4½ year old class. The percentage of juveniles corresponds closely to the numbers predicted by a Department of Natural Resources model developed by …

A Search For Lymphatic Tissue In The Mouse Pineal Gland, John B. Hutchinson

Masters Theses

There is recent evidence that the pineal gland in some species may have lymphatic qualities during early post natal life. In this study the development and structure of the pineal complex in the CDF₁ mouse is examined in fetal, neonatal, juvenile, and adult stages. The gland appears as an out growth of the dorsal wall of the third ventricle of the brain and at ten days gestation attains a mean size of 90 microns in the transverse and 35 microns in the median saggital plane. General and specific staining shows fetal and early post partum tissue to be compact …

Comparative Reproduction Of The Red-Eared Turtle, Pseudemys Scripta Elegans, In Heated And Natural Lakes, Gary Marshal Thornhill

Masters Theses

The effect of heating on aquatic ecosystems by energy producing power plants has not been fully determined. A comparative study of the reproduction of Pseudemys scripta was conducted in heated and natural lakes in southwestern Illinois from 30 March to 10 July, 1979. Lakes used were the same as those used for comparative growth studies of P. scripta by another researcher. Lake Baldwin (heated) has had a reduction in vegetation since that researcher's work. Temperatures were taken of air, water surface, and one meter deep.

Turtles were caught by hand, trammel nets, and in carp-baited hoop nets. Captured turtles were …

Nebraska Trapping, George Schildman, Frank Andelt, Jim Brunner

Nebraska Game and Parks Commission: Publications

Fur bearers and trapping played an important role in the exploration and development of Nebraska. The harvest of our fur-bearer resource is part of every Nebraskan's heritage. Wise use of the resource and consideration for other people's property and personal rights can insure that trapping will remain a part of the heritage of future generations. The purpose of this publication is to help insure this heritage ... through the educational process. Knowledge of and respect for the resource, as well as consideration for other people, are the keys to perpetuating trapping as an outdoor activity. While primarily designed to assist …

Winter Sampling Of Benthic Stream Fishes In Minnesota With A One-Man Net, James E. Erickson

Journal of the Minnesota Academy of Science

Newly designed one-man nets were used extensively between 1973 and 1977 to collect fishes in a variety of stream habitats in southeastern Minnesota. They proved to be especially effective In winter sampling of benthic stream fishes such as Etheostome zonale, Etheostome ceeruleum, Percina phoxocephala, Percina shumardi, Percina caprodes, Rhinichthyes cataractae, and Noturus flavus. Effectiveness and potential importance of these one-man nets as winter sampling devices was demonstrated during three consecutive winters of use In the Cannon River at Welch, Goodhue County, Minnesota.

Dirofilaria Immitis In The Wild Canids Of Illinois, Thomas J. Kick

Masters Theses

The heartworm, Dirofilaria immitis, is widespread in dogs in North America and has been reported in wild canids in many states. This is a report of this parasite in hearts removed from coyote, red fox and gray fox carcasses collected in Illinois. A total of 415 coyotes had a significantly higher infection rate (23.6%) than 225 red foxes (3.6%) and 99 gray foxes (3.0%). Infection rates in red foxes and coyotes were significantly higher in or near the Wabash Border Natural Division along the eastern side of the state, suggesting a relationship between infection rates and this region. The …

A Diet And Reproductive Study For Selected Species Of Malaysian Turtles, Colleen E. Kimmel

Masters Theses

Batagur baska, Callagur borneoensis, Cuora amboinensis, Cyclemys dentata, Orlitia borneensis, Siebenrockiella crassicollis, and Trionyx cartilagineus are suggested to be omnivorous by diet analysis. Cyclemys and Orlitia are the more herbivorous of the seven species examined. Batagur and Callagur are two closely related sympatric species that appear to have diverged sufficiently to eliminate competition for food resourses, as indicated by Morista's Index of Niche Overlap. Along the Perak River and it's tributaries in West Malaysia, Batagur and Callagur feed primarily upon the fruit of the berembang tree. In Trengganu (eastern Malaysia), the berembang is absent …

Analysis Of Sonagrams Of American Bison (Bison Bison), Harvey L. Gunderson, Brian R. Mahan

University of Nebraska State Museum: Mammalogy Papers

The sound made by adult male American bison (Bison bison) during agonistic behavior has been described as a "roar" because of its similarity to the roar of an African lion (Shult, 1972). Bulls roar any time of the year, but more commonly and most intensively during the rut when there are many agonistic confrontations between competing males. McHugh (1958), Shult (1972), and Petersburg (1973) have described this roaring and under what circumstances it occurs.

While the bull is roaring, its tongue is protruded and the sound is produced by forceful expiration of air over the vocal cords. In …

Apparent Chromosomal Heterosis In A Fossorial Mammal, John C. Patton, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

For the past decade, numerous investigators have attempted to explain the plethora of genetic polymorphism found in nature (see Ayala 1976). However, few researchers have been able to document how polymorphisms have been maintained, whether the polymorphisms were genic or chromosomal. Our investigations into the maintenance of a Robertsonian chromosomal polymorphism in the plains pocket goher, Geomys bursarius major, have revealed evidence that this polymorphism is maintained by differential viabilities of the three chromosomal morphs, with the heterozygote being favored.
