Effects Of 2, 4, 5-Trichlorophenoxyacetic Acid On Swiss-Webster Mice, Gerald S. Greer

Journal of the Arkansas Academy of Science

Pure and Commercial samples of the herbicide 2,4,5-trichlorophenoxyacetic acid (2,4,5- T) were tested on Swiss-Webster mice for: (1) interruption of the estrus cycle and (2) teratogenic effects. The estrus cycle of mice administered Commercial 2,4,5-T was interrupted in 42.9% of the animals and in 12.5% of the animals given Pure 2,4,5-T. No fetal abnormalities were found in pregnant animals treated with Commercial or Pure 2,4,5-T. Fetal resorptions were found in both treatment groups. Treatment with Pure 2,4,5-T produced a significant decrease in viable fetal weight and increased fetal deaths.

Yolk-Periblast Junction In Fundulus Heteroclitus, Claudia F. Bailey

Journal of the Arkansas Academy of Science

The yolk of teleost eggs becomes covered with a syncytial periblast during embryonic development. Nutrients must be transported through the periblast before they are available to the embryo. Tranmission electron micrographs of thin sections and of freeze-fractured replicas show a number of features at the yolk-periblast junction which may be correlated with yolk transport. These features include vesicle formation and exchange, channelization and interdigitation.

Journal of the Minnesota Academy of Science

Ranges of the 45 wild mammals occuring in southwestern Minnesota are discussed and documented. Eight other species that either formerly occurred in the area or might exist but have not yet been documented also are considered. Seven species are recorded from southwestern Minnesota for the first time: Scalopus aquaticus, Myotis keenii, Lasionycteris noctivagans, Marmota monax, Spermophilus franklinii, Tamiasciurus hudsonicus, and Rattus norvegicus.

Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri

Masters Theses

Hepatozoon and microfilariae are described from the blood of fox and gray squirrels captured in Coles and Lake Counties in Illinois during 1976 and 1977. The hepatozoon species is identified as Hepatozoon griseisciuri on the basis of parasite morphology and hosts. A higher rate of infection (35.7% : 11.1%) was observed in gray squirrels than in fox squirrels and more adults were infected than juveniles. No microfilariae were found in gray squirrels but fox squirrels had a 57.1% infection rate with no difference based on age. The observed microfilariae are similar to that described by Davidson from Maryland gray squirrels …

Duck Plague Virus An Investigation Of Cytopathic Effects, In-Vitro Host Range, And Inhibition By Phosphonoacetic Acid, Ronald Attanasio

Biological Sciences Theses & Dissertations

Duck plague is a hemorrhagic, necrotic disease found exclusively in the order Anseriformes, family Anatidae (ducks, geese, swans). The etiologic agent has been reported to be a herpes-like virus. The Holland strain of duck plague was found to induce cytopathic effects in cell culture (perinuclear vacuolation followed by lysis). A simple reproducible plaque assay for quantitating the virus was developed. Under conditions of the plaque assay, one-hit kinetics were observed. The host range of duck plague virus in cell culture was found to include the order Galliformes, family Phasianidae (pheasants, quails and partridges). Duck plague virus-induced cell culture cytopathic effects …

The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace

Masters Theses

A total of 38 Mus musculus were used to compare superovulation to normal ovulation in three different areas of the reproductive cycle. The areas studied include the fertilization and abortion rates, alternation of ovarian function, and normalization of estrus cycling. No statistically significant differences were noted between the two groups in either fertility rates or abortion rates. A distinct difference was noted in alternation of ovarian function. Normally ovulating mice showed a distinct right or left preference in the number of ova ovulated from each ovary. Animals showing a left preference exhibited approximately a 2:1 ratio and animals with a …

Comparison Of Coyote And Coyote X Dog Hybrid Food Habits In Southeastern Nebraska, Brian R. Mahan

University of Nebraska State Museum: Mammalogy Papers

The recent taxonomic study by Mahan et al. (1978) documented the occurrence of coyote (Canis latrans) X dog (C. familiaris) hybrids in Nebraska. This study, and those by Freeman (1976) in Oklahoma and Gipson et al. (1974) in Arkansas show coyote x dog hybrids, though not abundant, to be numerous in some areas. The purpose of the present study was to compare the stomach contents of coyote x dog hybrids collected by Mahan et al. (1978) from southeastern Nebraska with those of contemporary coyotes. Stomachs of 12 coyote x dog hybrids and 16 coyotes collected November …

Karyotypes Of Shrews Of The Genera Cryptotis And Blarina (Mammalia: Soricidae), Hugh H. Genoways, James C. Patton Iii, J. R. Choate

Cryptotis parva has a diploid number of 52 and a fundamental number of 50. Blarina brevicauda in Nebraska and Pennsylvania has a diploid number of 49 or 50 and a fundamental number of 48. Blarina carolinensis in Nebraska and Kansas has a diploid number of 52 and a fundamental number of 62. The X-chromosome in all 3 species is a large metacentric chromosome. The Y-chromosome is a small acrocentric in Blarina, whereas in Cryptotis it is a small subtelocentric.

Live Trap Preference Among Grassland Mammals, Robert K. Rose, Norman A. Slade, James H. Honacki

Biological Sciences Faculty Publications

In two independent studies, small mammals of grassland communities in eastern Kansas, when given a choice, preferred Fitch to Sherman live traps. Except for the harvest mice in the demographic study, the type of preferred trap and magnitude of selection was remarkably comparable, with microtines showing slight, and cricetines strong, preferences overall. The merits of each type of trap are compared, and related to season, weather, prior experience, and trap-associated mortality.

A Taxonomic And Ecologic Study Of The Riverbottom Forest On St. Mary River, Lee Creek, And Belly River In Southwestern Alberta, Canada, Robert K. Shaw

Great Basin Naturalist

The riverbottom forest community of St. Mary River, Lee Creek, and Belly River in southwestern Alberta, Canada, is a unique ecological entity characterized by poplar species having their major Alberta distribution along these streams. Stands in the community are dominated by three tree species, six shrub species, and nine herb species. Establishment of the community is dependent on climate and substrate; destruction is the result of progressive lateral stream-flow erosion. Soils are sandy loams above gravel, with pH values of 7.7 to 8.0 and soluble salt concentrations of 176 to 458 parts per million. Trees in mature stands averaged 23.0 …

The Natural History Of The Workerless Ant Parasite, Formica Talbotae, Mary Talbot

Faculty Scholarship

The ant Formica talhotae Wilson is a workerless social parasite of the microgrna group, which forms mixed colonies with the host ant Formica ohscuripes Fore!. Queens produce males and females only and there is also no worker brood of F. obscuripes in the parasitized colonies. The small alates have a long flight period stretching from mid-June to late September, with flights taking place on every suitable morning when the temperature is above 71° and rising, when the sun is shining, and when there is no appreciable wind. Flights are best between 78° and 83° F. Once up on plants, alates …

Federal Regulations Pertaining To Collection, Import, Export, And Transport Of Scientific Specimens Of Mammals, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The routine tasks of mammalogists whose research or curatorial activities include collecting, importing, processing, exporting, or interstate transporting of living or dead scientific specimens of mammals have become increasingly complicated by newly enacted (or more rigorously enforced) Federal regulations. These regulations were necessary largely because of the activities of non-scientists, but their provisions have had a tremendous impact on the activities of scientists (especially museum-based systematists and ecologists). Most mammalogists have expressed a willingness to comply with the regulations (although nearly all agree that administration of the permit system should be consolidated into a single office) if they can obtain …

A New Species Of Chiroderma From Guadeloupe, West Indies (Chiroptera: Phyllostomidae), Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

During the course of a study of the bat faunas of the Caribbean islands we obtained a specimen of Chiroderma from the island of Guadeloupe in the Lesser Antilles. The nearest known populations of this genus occur on Tobago and Trinidad (C. villosum and C. trinitatum). approximately 550 kilometers to the south. This specimen represents a distinct new species that appears to be most closely related to C. doriae and C. villosum. This new species is named and described.

Distributional Records Of Amphibians And Reptiles From Coastal Plain Of Arkansas, Edmond J. Bacon Jr., Zane M. Anderson

Journal of the Arkansas Academy of Science

Distribution of amphibians and reptiles in the West Gulf Coastal Plain and Mississippi Alluvial Plain is not well known because extensive collecting has not been done in these areas and data in museums have not been published. New distributional records for three salamanders (Desmognathus fuscus brimleyorum, Manculus quadridigitarus, Plethodon glutinosus glutinosus) , two anurans (Rana areolata circulosa, Scaphiopus holbrooki holbrooki), and one snake (Lampropeltis doliata amaura) are presented. Additional collecting will be necessary to determine the exact range and status of the secretive species.

Continuation Of Mourning Dove Studies In Clark County, Arkansas, With Emphasis On Cyclical Behavioral Patterns, Thurman Booth, Fred L. Burnside Jr., Jan Burnside, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

In conjunction with the U.S. Department of Interior, Fish and Wildlife Service, the Henderson State University Biology Department has continued a study of mourning doves in Clark County, Arkansas, with emphasis on cyclical behavioral patterns. Three hundred forty-three mourning doves were baited, trapped, and banded to obtain information concerning age, sex, populations, retraps, abnormalities, migrations, trap injuries, cyclical behavioral patterns, and other factors.

Characteristics And Behavior Of Guineafowl And Domesticated Chicken Hybrids, Earl L. Hanebrink

Journal of the Arkansas Academy of Science

The description, behavior, and morphologic measurements are presented for two hybrid crosses of domesticated chicken and guineafowl. The ease at which gallinaceous birds hybridize might warrant a closer look at the classification system. Possibly the number of families in the superfamily Phasianoidea should be reduced as some other researchers suggest.

Hormone Receptor Site Maturation In The Secondary Sex Organs Of Immature Male And Female Rats, K. J. Thomas

Journal of the Arkansas Academy of Science

The effect of a combined dose of pregnant mares' serum (PAAS) and human chor ionic gonadotropin (HCG) on male and female rats 2-25 days old was studied. Groups of animals were given injections for three days, then sacrificed on the fourth day. All injections were begun on the 2nd, 7th, 12th, 17th, and 22nd day of life. Ovaries, uteri, seminal vesicles (SV), and ventral prostate (VP) were removed, dissected free of fat, and weighed. Because uterine weight increased earlier than either SV or VP weight, the ability of the uterus to respond to exogenous estradiol and of the SV and …
