Analysis Of Gray Fox (Urocyon Cinereoargenteus) Fur Harvests In Arkansas, Gary A. Heidt, James H. Peck, Lew Johnston

Journal of the Arkansas Academy of Science

An investigation was conducted on gray fox (Urocyon cinereoargenteus) fur harvest in Arkansas. Data were gathered from a mail survey of Arkansas trappers and from Arkansas Game and Fish Commission fur harvest records from 1939 to 1983. Analyses of these data demonstrated: 1) gray fox were abundant statewide with lower levels in the Delta region; 2) there was a need for fox trappers to keep better records on their trapping efforts, success and composition of catch, including sex and age data; 3) market price: harvest correlation was high (r = 0.956, p < .001); 4) over the past 10 years, the Ozark Mountain region provided the greatest contribution to annual fox harvests, the Ouachita Mountain and Gulf Coastal Plain regions were similar to each other, but lower than the Ozarks, and the Delta region contributed the least, but with a generally stable harvest.

Breeding Birds In Cedar Stands In The Great Dismal Swamp, Karen A. Terwilliger, Robert K. Rose

Biological Sciences Faculty Publications

The Great Dismal Swamp located in the coastal plain on the Virginia- North Carolina border, has long been recognized as a vegetationally distinctive region with many unusual geological and biological features. Formerly at least twice the currently estimated size of 85,000 hectares (Carter 1979), the Great Dismal Swamp is still shrinking because of a dropping water table caused by more than 200 years of logging, ditching, and other human activities. In 1973, the Union Camp Corporation donated a 19,871-hectare tract located near Suffolk, Virginia. to The Nature Conservancy, which transferred the land to the U.S. Fish and Wildlife Service. This …

Alcataenia Campylacantha (Krabbe, 1869) From Pigeon Guillemots, Cepphus Columba Pallas, And Black Guillemots, Cepphus Grylle (Linnaeus), And Alcataenia Sp. Indet. (Cestoda: Dilepididae) From Kittlitz's Murrelets, Brachyramphus Brevirostris (Vigors) In Alaska, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt.

Alcataenia Longicervica Sp. N. From Murres, Uria Lomvia (Linnaeus) And Uria Aalge (Pontoppidan) In The North Pacific Basin, With Redescriptions Of Alcataenia Armillaris (Rudolphi, 1810) And Alcataenia Meinertzhageni (Baer, 1956) (Cestoda: Dilepididae), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia longicervica sp. n. (Cestoda: Dilepididae) is described from murres, Uria spp., in Alaska and other localities in the Pacific basin. From Alcataenia armillaris (Rudolphi, 1810), which it most closely resembles, A. longicervica is distinguished by larger size of organs (cirrus sac, vitelline gland, and seminal receptacle), greater number of testes, and extremely long neck. In specimens of A. longicervica there are 22-27 rostellar hooks distributed in two rows. Hooks in the anterior row measure 41-49 μm in length while those in the posterior are 38-48 μm. Two species of Alcataenia, A. armillaris and A. meinertzhageni (Baer, 1956), both …

Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.

The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …

Phylogeny And Paleobiogeography Of Short-Tailed Shrews (Genus Blarina), Cheri A. Jones, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Dental measurements of Pleistocene and Holocene shrews of the genus Blarina were analyzed in a multivariate assessment of phylogeny and paleobiogeography of the genus. Blarina brevicauda, or an indistinguishable precursor, apparently was the ancestral form. Two semispecies, brevicauda and talpoides, are recognizable early in the fossil record; these two phena probably appeared as a result of increasing diversity'in the environment of the late Irvingtonian. Evidently, repeated fluctuations of climate and the subsequent changes in range have not been sufficient to cause the cessation of gene flow necessary to complete speciation.

A second species, B. carolinensis, appeared in …

Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One hundred forty-five cliff swallows, Petrochelidon pyrrhonota, were examined for cestodes in two separate surveys in Weld County, Colorado. Seven species representing four genera were found. Angularella audubonensis sp. n. is differentiated by the small size of the rostellar hooks (8.4-13.5 μm) and the medial relationship of the cirrus pouch to the osmoregulatory canals. Other species collected were Angularella beema, Anonchotaenia globata, Mayhewia ababili, Vitta magniuncinata, Vitta parvirostris and Vitta riparia. Seven new hosts and geographic distribution records were established for Colorado, and six new records were determined for North America.

Factors Affecting Reproductive Success Of Bonytail Chubs And Razorback Suckers In Lake Mohave, Michael A. Bozek, Larry J. Paulson, James E. Deacon, U.S. Department Of Interior, Fish And Wildlife Service

Publications (WR)

Razorback suckers (Xyrauchen texanus) and bonytail chubs (Gila elegans) were once widespread throughout the Colorado River system. The ranges and populations of these native species and others have declined in the past 50 years. Bonytail chubs appear to be extremely rare and possibly nearing extinction in the Upper Colorado River Basin. The razorback sucker is widely distributed in the upper river but is considered rare throughout most of that range and is also rare in the Grand Canyon. Razorback suckers are abundant only in a few habitats in the upper river. They congregate and spawn over …

Use Of Skelettochronology In Age Determination Of American Toads (Bufo Americanus) From East Central Illinois, Philip M. Acker

Masters Theses

A skelettochronological technique was applied to the phalanges of the American toad, Bufo americanus, from east central, IL. In hematoxylin-stained cross-sections of the phalanges, suspected year rings are formed which can be used to age individuals. This method allows for aging without destructive sampling of toad populations.

A majority of the male toads from two choruses were estimated to be 2 or 3 years old, while most of the females from the same two sites were in the 3 or 4 year age class. Females were larger than males in the 3 and 4 year age classes, and overall, …

Operant Conditioning In The Water Snake (Nerodia Sipedon), Angela R. Deitz

Masters Theses

Six subjects of Nerodia sipedon were tested for runway acquisition. Five of six subjects met criterion for runway learning, demonstrating a significant decrease over the 25 day testing period in mean latency and running times. Four subjects completed 170 trials in a T-maze to test two-choice discrimination and reversal learning. All subjects met criterion for the initial discrimination and one reversal while two subjects completed four reversals and one subject met criterion for six reversals. Results are similar or superior to those previously reported for reptiles and other non-human vertebrates.

Operant Conditioning In The Psittacine, Amazona Amazonica, Gloria J. Nadolski

Masters Theses

Two Orange-winged Amazon Parrots, (Amazona amazonica) were subjected to operant conditioning involving three tests: two-choice spatial discrimination and reversal, three-choice color discrimination and reversal, and the oddity principle. Results of the habit reversal tests were compared to those of Gossett (1968) to determine the phylogenetic ranking of the learning capabilities of psittacines. In the first two habit reversal tests, the subjects completed twenty reversals using sunflower seeds as positive reinforcements. In the oddity principle test, the parrots completed the equivalent of 20 reversals, again using sunflower seeds. Criterion was met when they completed 8 consecutive correct choices with …

A Comparison Of The Temporal Spawning Distributions And Growth Rates Of Young-Of-The-Year Redear Sunfish (Lepomis Microlophus) And Bluegill (Lepomis Macrochirus) In Three Illinois Impoundments, Craig Douglas Schmittler

Masters Theses

The purpose of this study was to compare the temporal spawning distribution and growth rates of bluegill (Lepomis macrochirus) and redear sunfish (Lepomis microlophus) in Illinois impoundments. Otolith sagittae were used to age the fish and to determine the intervals of successful spawning for both species.

Readear sunfish initiated spawning slightly before or a the same time as bluegill; however, bluegill spawned for twice as long as redear sunfish in all study impoundments. The earliest spawned fish of both species showed the fastest growth and the earliest spawned redear sunfish grew faster than did the earliest …

A Report On A Pilot Study On Cattle Grazed Patches In Herbaceous Vegetation, Victor Povilaitis

Undergraduate Honors Capstone Projects

Since the late 1960's, the term station (Goddard 1968), feeding station (Novellie 1978, Underwood 1982), and feeding site (Underwood 1983) have been used to describe the area in front of a foraging animal in which it can access forage without moving its front legs. The area is a hypothecial semicircle in front of the grazing animal, but the vegetation actually impacted by defoliation may be considered a "grazed patch," which may be the sum of several feeding stations. As animals graze the vegetation in an area, grazed patches are created. Presently, it is undocumented if such patches influence the behavior …

The Dynamics Of Animal Distribution: An Evolutionary/Ecological Model, Charles H. Smith

Faculty/Staff Personal Papers

Investigators have sometimes assumed that the factors underlying animal distribution are too complex to lend themselves to normative modelling. In this work, a model of environment and community interaction is constructed which lends itself to the latter kind of interpretation. It is posed that spatially-varying rates and magnitudes of availability of moisture at given locations act as stresses on the nature of community infrastructure, and secondarily on the rates at which new populations may become integrated into these. Populations are thereby viewed as tending to change range in common directions, though at overall rates remaining peculiar to each. This interpretation …

Pine Siskin Nests At Wayne State College, A. Jewell Schock

Nebraska Bird Review

On 29 April 1976 I observed a number of Pine Siskins in the elm and blue spruce trees on the Wayne State College campus, Wayne, Nebraska. They were actively flying back and forth between the trees so I could not determine the exact number of them, but they would have numbered less than a dozen.

On 30 April I saw that a Pine Siskin appeared to be building a nest in a blue spruce tree, about five feet above the ground. I continued to watch from a safe distance for the next few days. By 5 May the nest appeared …

Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes

Papers in Ornithology

Breeding habitat of the least tern is made up primarily of coastal beaches and inland river sandbars. Populations of the interior (Sterna antillarum athalassos) and east coast (S. a. antillarum) subspecies are now declining (Marshall et al. 1975, Duffy 1977, Jernigan et al. 1978) and the western subspecies (S. a. browni) is endangered (Wilbur 1974). Although coastal populations have received considerable attention (Wolk 1974, Atwood et al. 1977, Blodgett 1978), little research has been conducted on the interior race (Hardy 1957, Downing 1975).

The piping plover inhabits river sandbars and sand beaches and, like …

The Effects Of Photoperiod On The Prolactin Cells Of Notropis Cornutus (Mitchell), Matthew Kevin Hettinger

Masters Theses

Three groups of the common shiner (Notropis cornutus, Mitchell) were adapted to three different photoperiods. These photoperiods were 16L:8D (summer), 12L:12D (controls), and 8L:16D (winter). The prolactin cells were studied histologically and morphologically with respect to staining characteristics, cell and nuclear morphology, nuclear size, and cellular density. The prolactin cells of those fish under the long photoperiod exhibited greater cellular activity than the controls as evidenced by an increase in nuclear size, cellular density, and by becoming more circular. The prolactin cells of those fish under the short photoperiod exhibited the same characteristics as those in the long photoperiod. The …
