Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.

The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …

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.

Vegetative Study At The Duck Field Research Facility, Duck, North Carolina, Gerald F. Levy

Biological Sciences Faculty Publications

The Duck Field Research Facility is located on the Outer Banks of North Carolina, a series of offshore sandbars extending from the Virginia- North Carolina border southward about 200 miles to Bogue Inlet, North Carolina. These bars lie almost parallel to the mainland and are separated from it by shallow sounds of varying widths.

The study area is included in Currituck Bank (North Bank), which extends from the Virginia-North Carolina boundary southward to the town of Nags Head, a distance of about 45 miles (Fig. 1). The bank was originally demarcated by two inlets; Old Currituck Inlet, which was located …

The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf

Publications (WR)

The distribution of water and of enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash was determined. Determination of distribution patterns was attained by applying the concept of the population component ratio of enteric bacteria. The development and application of new techniques and methods implicit in the application of the "component ratio" concept are discussed. The unreliability of thoroughly referenced techniques and methods generally accepted as standard are treated in detail. Physical factors affecting the distribution and deposition of enteric bacteria (including those of special public health importance) in Las Vegas Bay are also discussed.

The Distribution Of Submersed Hydrophytes In Currituck Sound, Steven Harry Davis

Biological Sciences Theses & Dissertations

The rooted submergent flora of Currituck Sound, North Carolina was determined, and the distributions of its species investigated with respect to salinity, substrate texture, depth, pH, turbidity and species co-occurrence. Eight species of hydrophytes were found: Potamogeton pectinatus, Fotamogeton perfoliatus, Ruppia maritima, Zannichellia palustris, Najas guadalupensis, Elodea nuttallii, Vallisneria americana, and Myriophyllum spicatum. The mean salinities at which each species occurred ranged from 1.0 ppt for E. nuttallii to 3.1 ppt for Z. palustris, Ruppia maritima, Z palustris and V. americana were the only species that commonly occurred on coarse-grained substrates. Elodea nuttallii and N. guadalupensis …

Variation In The Ecology Morphology And Behavior Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonchidae) From Different Habitats, Gary Wayne Dickson

Biological Sciences Theses & Dissertations

Populations of the troglobitic amphipod Crangonyx antennatus living in two distinct aquatic habitats were examined for possible variations in their ecology, morphology and behavior. Collections were made seasonally for one year in six Lee Co., Virginia caves, three containing mud-bottom, drip pools and three with small gravel stream habitats. Environmental parameters thought to influence population variation were quantitatively and qualitatively recorded in each of the six caves.

Amphipod densities, body length, female maturity, clutch number and stream washout rates were found to be greater in drip pool habitat populations. Variation was also observed in body coloration and antennal segment-body length …

Influence Of A Dry Wash Habitat On Distribution And Movement Of Heteromyid Rodents, Jeffrey S. Green

Theses and Dissertations

Three heteromyid rodent species were studied in relation to a large dry wash in Millard County, Utah, during the summer, 1974. Data were gathered with three trapping grids and analyzed to determine if the dry wash influenced rodent movement and distribution patterns. Dipodomys ordii and Dipodomys microps were distributed non-randomly in the dry wash and adjacent habitat, but Perognathus Zongimembris seemed to be randomly distributed. Dipodomys ordii was significantly correlated with wash habitat, but D. microps was found most frequently in upland areas. Soil and vegetative differences and competition were possible causes for the observed distribution. The wash was observed …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iii-The Effects Upon The Zooplankton Associations, Edgar D. Short, Eugene H. Schmitz

Arkansas Water Resources Center Technical Reports

The primary purpose of the zooplankton phase of the coordinated study was to attempt to evaluate the effects of dredging operations on the abundance, distribution, composition and complexity of the zooplankton communities within the aquatic system of the Arkansas River. The other phases of investigation include fish, macroinvertebrates, phytoplankton and some physico-chemical parameters. The lack of baseline data, needed for measurement of previous ecological conditions from which to detect past and future changes, proved to be a major impediment to any evaluation. Although the study involved only about 240 miles of the river in Arkansas, it should serve as an …

The Nursing Posture Of Domestic Sows And Related Behaviour, D. Fraser

Rearing Behavior Collection

The nursing behaviour of the sow commonly involves upward rotation of the udder, movements of the head and legs, and rhythmic grunting. Aspects of this behaviour were studied in several experiments with pregnant females, juveniles males, and suckling piglets. Many pregnant females lay down and assumed the nursing posture when their udders were first rubbed by hand. Those which initially appeared agitated in the experimenter's presence often failed to do so until after some habituation to the procedure. When the upper and lower rows of teats were rubbed alternately, the udder was usually rotated toward the stimulation. This rotation, like …

A Revision Of The Genus Strategus (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

Bulletin of the University of Nebraska State Museum (1924–2023)

The New World genus Strategus Kirby is here defined and revised for the first time. Eight species are described as new: S. atlanticus, S. caymani, S. craigi, S. hipposiderus, S. howdeni, S. longichomperus, S. symphenax, and S. tarquinius; 12 new junior synonyms are established (including the rejection of six previously valid species)'; one species is raised from synonymy; and two new replacement names are proposed. Strategus now contains one fossil species and 31 valid extant species. A key to the males and females of all the species is provided for the first …

Lupin Split Seed : A Disorder Of Seed Production In Sweet, Narrow-Leafed Lupins, M W. Perry, J. W. Gartrell

Journal of the Department of Agriculture, Western Australia, Series 4

Commercial seed production from narrow-leafed lupins (Lupinus angustifolius L.) began in Western Australia in 1967, based on the newly-bred low alkaloid cultivar Uniwhite. The release of improved cultivars has led to the crop's wide acceptance and more than 100 000 ha were sown to sweet lupins in 1975.

With the greater area and wider range of soil types devoted to lupins, a developmental abnormality of the seeds, which became known as "split seed", was observed in some situations.

Green Lemons Safe From Fruit Fly, A N. Sproul

Journal of the Department of Agriculture, Western Australia, Series 4

Importers' demands for fruit imports to be free of local pests places great restrictions on the movement of fruit between States, between countries, and sometimes within a State.

In Western Australia a Fresh Fruit Disinfestation Committee was formed in 1969 to direct State research aimed at developing techniques for post-harvest fruit sterilsation Programmes are supported by State and Federal funds and, in W.A., have provided staff and facilities to work on Mediterranean fruit fly. Parallel work with Queensland fruit fly and codlin moth is being done in New South Wales and Victoria.

New Records Of Native And Introduced Plants From Nebraska, Steven P. Churchill, Robert B. Kaul, David M. Sutherland

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Recent field work in Nebraska by staff of the University of Nebraska Herbarium has produced a number of records of previously uncollected specimens and has confirmed the presence of species collected only a few times long ago. Some of the records are of American species which are indigenous to Nebraska or which have recently spread to the state, while other records are of foreign species which are thoroughly established in the wild. Some of these are potentially serious weeds, though none have reached that stage yet.

All specimens cited are deposited in the University Herbarium in Nebraska Hall, Lincoln, except …

Aspen Forest After Harvest, Norbert V. Debyle

Aspen Bibliography

Aspen is a unique forest tree with respect to regeneration. It produces abundant root suckers, up to 40,000 per acre are common, after clearcutting or fire removes the parent stand. The rapidly growing sucker stand competes well with other vegetation, but is susceptible to destruction by excessive ungulate browsing. Clearcut areas produce more streamflow and more growth on shrubs and herbaceous vegetation than does the uncut forest. The patchwork of age classes that results from even-age management optimizes wildlife habitat requirements for several desired species.

Macrobenthos Population Changes In Crystal Lake, Arkansas, Subsequent To Cage Culture Fish, James C. Adams, Raj V. Kilambi, William A. Wickizer, Arthur V. Brown

Journal of the Arkansas Academy of Science

A three-year study was conducted to determine the possible effects of cage culture of fish on the environment of Crystal Lake, Arkansas. The investigation consisted of three periods: pre- (November 1971-October 1972), during- (November 1972-October 1973), and post- (November 1973-October 1974) cage culture. Numbers and biomass of benthos per square meter for pre-, during-, and post-culture periods were 1353 (10.0g), 730 (8.8g), and 1028 (4.1g), respectively. Numerically, Chaoborus sp., Chironomidae, and Oligochaeta comprised more than 97%. Chaoborus was the most numerous organism before fish culture (>68%), but dominance shifted to the Oligochaeta (>58%) after culture.

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.

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.

Update Of Arkansas Odonata (Anisoptera), John D. Rickett

Journal of the Arkansas Academy of Science

Seventy-five species of dragonflies have been reported in Arkansas. The present study provides 43 species; records of the other 32 are drawn from the literature and personal communication with individuals. A new species, Gomphus ozarkensis, described from western Arkansas in 1975 on the basis of minimal data emphasizes the need for extensive work in this area. Opportunities to collect and identify additional species are discussed.
