Incorporation Of Carbon-14 Metabolites Into The Sex Pheromon 26-Dichlorophenol Of Dermacentor Andersoni Stiles; And The Disruption Of Pheromone Activity In D. Andersoni And D. Variabilis (Say) By Quinones, Daniel Martin Gainsburg

Biological Sciences Theses & Dissertations

The Rocky Mountain wood tick, Dermacentor andersoni Stiles, injected with (u-¹⁴c) sodium acetate or DL-(benzene ring-u-¹⁴c) tryptophan for in vivo studies, was found to produce sex pheromone, 2,6-dichlorophenol, containing ¹⁴c activity. Ambiguous results were obtained with L-(u- ¹⁴c) tyrosine, and no incorporation of ¹⁴c label into pheromone was observed with DL-(ring-u- ¹⁴c) phenylalanine or DL-(side chain-3-¹⁴c) tyrosine. Attempts were made to determine the site of synthesis, but in vitro studies proved inconclusive.

Disruption of sex pheromone activity in D. andersoni and the American dog tick, D. variabilis (Say) was achieved …

A Multivariate Study Of The Family Molossidae (Mammalia, Chiroptera) : Morphology, Ecology, Evolution, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

The purpose of my study is to examine as many species of the family Molossidae as possible and to determine, with the aid of numerical methods, what natural groups exist within the family. Sneath & Sokal (1973) discuss the methods and reasons for this kind of analysis. A natural group of organisms as here defined is one in which its members share a close phenetic relationship. Phenetic relationship is defined as "similarity (resemblance) based on a set of phenotypic characteristics of the objects or organisms under study," (Sneath & Sokal, 1973, p. 29), and is distinct in definition from phylogenetic …

Museums Are More Than Elephant Graveyards, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

I suspect many people do not know what natural history museums are all about. These museums hold nature's works of art, instead of just man's. There are not many museums of natural history and those few are usually in big cities.

Field Museum of National History in Chicago is one of the largest in the world, along with the British Museum of Natural History in London, the Smithsonian (U.S. National Museum) in Washington, and the American Museum of Natural History in New York. These are the museums that have the actual skeletons of dinosaurs, or stuffed elephants, poised in combat, …

WHITE-WINGED SCOTER. On 1 May 1980 I had a White-winged Scoter in the yard, at most times not more than 15 to 20 feet away from me. It was here an hour or so before the neighbor's cat caused it to fly. I take it that it was very tired or sick because it would just keep moving enough that I couldn't get any closer.

1980 Christmas Count

Nebraska Bird Review

One hundred and two species (three more than last year) were reported in the 1980 Christmas Count, and three species (two more than last year) were reported present during the count week but not seen on the count day. These increases were in spite of one less count Crawford - this year. Two additional races were reported, compared to three last year. The individual count this year was 317,910, compared to 188,102 last year, with the Snow Goose count at Omaha, particularly, and at DeSoto and the Mallard count at DeSoto accounting for more than the difference between the two …

A New Species Of Rhynchomys (Muridae) From The Philippines, Guy G. Musser, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

". . . Mr. Whitehead has made a most wonderful and unexpected discovery, that of a new and peculiar Mammal-fauna inhabiting the Luzon highlands, and, so far as is yet known, mostly isolated on a small plateau on the top of Monte Data, in the centre of Northern Luzon, at an altitude of from 7000 to 8000 feet." With this dramatic announcement, Oldfield Thomas (1898:377) introduced to naturalists the spectacular rats found by Whitehead: Crateromys schadenbergi, Carpomys melanurus, C. phaeurus, Batomys granti, Chrotomys whiteheadi, Celaenomys silaceus, and Rhynchomys soricoides. One of the most interesting of these to Thomas was …

Correspondence Of Food Habits And Morphology In Insectivorous Bats, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

In a morphometric study of molossid bats (Freeman, in press), I found that the first principal component (PC) reflected overall size. The second PC was concerned with a suite of jaw and skull measurements that separated molossids with thicker jaws, fewer but larger teeth, and welldeveloped cranial crests (i.e., bats with robust skulls) from those with thinner jaws, more but smaller teeth, and less developed cranial crests. Subsequently, I found (Freeman, 1979) that molossids with robust skulls ate hard-shelled insects such as beetles. and that molossids with gracile skulls ate soft-bodied insects such as moths. Given these conclusions I was …

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 …

Alternative Hypotheses On Ecological Effects Of Meningeal Parasite (Parelaphostrongylus Tenuis), Glen F. Cole

Journal of the Minnesota Academy of Science

P. tenuis is a ubiquitous parasite of white-tailed deer (Odocoileus virginianus) that can cause mortality in woodland caribou (Rangerifer tarandus) and moose (Alces alces). A hypothesis that P. tenuis prevents overlapping distributions of these species in southern boreal regions was inconsistent with distribution records. A revised hypothesis that P. tenuis does not prevent overlapping distributions if deer exist at natural densities was consistent with these records but did not state the parasite's ecological effects. A hypothesis that P. tenuis allows deer to outcompete woodland caribou or moose on portions of natural environments or in man-modified environments where deer densities are …

Distribution Of Small Mammals On The Apostle Islands, Gail E. Kantak

Journal of the Minnesota Academy of Science

Five weeks of small mammal trapping on the Apostle Islands in 1978 yielded few captures. The low capture rate was attributed to low invasion rates and high extinction rates. Distribution records of small mammal species on individual islands were compiled from studies conducted as early as 1917. The distribution of many small mammal species on these islands remains largely undocumented, and further study is desirable before the patterns are disrupted by human activity.

Fisheries Report No 43 - A Pit Trap Survey Of Small Mammals, Lizards And Frogs On The Two Peoples Bay Nature Reserve, Stephen D. Hopper

Fisheries Research Reports

Ten pitlines were placed in open low woodlands near Moates Lake and in upland and coastal heathlands near Mount Gardner on Two Peoples Bay Nature Reserve during February 1980 and February 1981. The trapping program established that Common Dunnarts (Smitnthopsts murina) and Honey Possums (Tarstpes spencerae) were widespread in the reserve, and added three lizards and one frog to the list of vertebrates known to occur on the reserve.

Twenty mammals (15 native and 5 feral), four snakes, fifteen lizards, one tortoise and six frogs are now known on Iwo Peoples Bay Nature Reserve. They constitute a representative sample of …

A Function Of The Subelytral Chamber Of Tenebrionid Beetles, Con Slobodchikoff, Kim Wisman

Entomology Collection

1. The subelytral chamber is an air space between the elytra and the dorsum of the abdomen of some Tenebrionid beetles. Postulated functions for the subelytral chamber have been a reduction of transpiratory water loss and a thermal buffer for heat flow from the elytra to the abdomen.

2. We show that there is a significant correlation between water loss and the depth of the subelytral chamber.

3. This implies that the chamber may be a structure that permits the rapid expansion of the abdomen, providing the beetles with a mechanism by which they can quickly drink large quantities of …

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 …

River Otter In Arkansas: I. Distribution And Harvest Trends, C. Renn Tumlison, Anthony W. King, Lew Johnston

Journal of the Arkansas Academy of Science

River otter (Lutra canadensis) management in Arkansas is hampered by a lack of information on population parameters. This initial study on the biology of Arkansas river otter is concerned with present distribution and harvest trends. Otter occur throughout Arkansas, except in the upper Ozark region. A distributional shift, apparently along the Arkansas River, has led to an increase in otter harvest in the Ouachita Mountain region. A dramatic increase in otter harvest over the past four years (1976-1979) is attributable, in part, to a pelt price increase. Additionally, nuisance level beaver (Castor canadensis) populations and an extended trapping season for …

Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener

Masters Theses

Gastrointestinal tracts of 45 coyotes, Canis latrans, from southeastern Illinois were examined for cestodes and nematodes. The following parasites and incidences (%) were observed: Taenia sp. (71.1); Physaloptera sp. (53.3); Ancylostoma sp. (20.0); Ascarididae (11.1); Thelazia sp. (2.2); Trichuris sp. (2.2); Uncinaria sp. (2.2). Ancylostoma sp. occurred significantly more often in juveniles than adults. Parasites averaged low numbers per coyote, and no ulceration or blood in the tracts was seen.

A Redescription Of Spironoura Duyagi From The Stomach Of Malayan Box Turtles (Cuora Amboinensis), Rex A. Kuye

Masters Theses

Two hundred and twenty-six worms taken from the stomachs of three Malayan box turtles (Cuora amboinensis) were studied. The worms were identified as Spironoura spp., and their numerical measurements and morphological details compared to other described species in the genus. The nematodes, generally, conformed to published descriptions of Spironoura duyagi, but varied so widely with regards to presence or absence of key diagnostic features that a complete taxonomic analysis was undertaken.

Attributes Of Dispersing Meadow Voles In Open-Grid Populations, Raymond D. Dueser, Marcia L. Wilson, Robert K. Rose

Biological Sciences Faculty Publications

Dispersal was investigated in two open-grid populations of meadow voles, Microtus pennsylvanicus (Ord, 1815) an central Virginia (U.S.A.) from November 1974 to April 1978. "Dispersal" was defined as immigration onto open, occupied population grids. Dispersers were distinguished from residents by weight at first capture. Individuals first captured at weights <30 g were classified as residents; those first captured at >30 g were classified as dispersers. Three independent lines of evidence support the validity of the 30-g criterion for recognizing dispersers in these vole populations. With frequent trapping and high trappability, particularly of young animals, this open-grid method of study offers two advantages in the study of dispersal. First, dispersers identified …

Biology Of The Striped Bass, Morone Saxatilis, In Beaver Reservoir, Arkansas, Raj V. Kilambi, Alex Zdinak Jr.

Journal of the Arkansas Academy of Science

Growth, length-weight relationship, maturation and food habits of striped bass from Beaver Reservoir were studied. No significant difference in growth in length between sexes was found. Growth of the Beaver Reservoir striped bass was similar to that of anadromous and freshwater populations. Males and females showed significant difference in length-weight relationship, and females exhibited isometric growth. The gonosomatic indices (GSI) of males ranged from 4.50 to 7.09 and were classified as mature fish. Female striped bass with GSI of 2.62 and above had three size groups of ova and were considered as maturing and mature. The food was primarily composed …

Maturation, Spawning Period, And Fecundity Of The White Crappie, Pomoxis Annularis Rafinesque, In Beaver Reservoir, Arkansas, Janet L. Thomas, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Gonosomatic indices and ovum diameter frequency distributions showed that the Beaver Reservoir white crappie spawns from late April through May. During the spawning season females release eggs more than once. Various stages of ovarian ovum development were described. Sexual maturity was found in 2-year-old females of 197 mm and 3-year-old and older fish. Regression analyses of fecundity on total length, weight and age of white crappie indicated that the fish weight was the best predictor of fecundity.
