A Study Of Nongeographic Variation In Tatera Leucogaster (Mammalia: Rodentia) From Botswana, Pierre Swanepoel, Duane A. Schlitter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Specimens of Tatera leucogaster from six localities in Botswana were tested for variation with age, secondary sexual variation, and individual variation. Of the six age classes recognized, categories I, II, and III each formed their own group, whereas cat egories IV, V, and VI were not separable on a morphometric basis and were considered to be adults. Significant secondary sexual variation was found only in depth of braincase in which females were larger. The only character exhibiting unusually high individual variation was length of posterior palatal foramen. All other characters exhibited individual variation within acceptable limits.

A Systematic Review Of The Olive-Backed Pocket Mouse, Perognathus Fasciatus (Rodentia, Heteromyidae), Daniel F. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Geographic variation in Perognathus fasciatus Wied and the identities of specimens of P. fasciatus and P. flavescens from areas of potential sympatry were investigated. Populations of P. fasciatus from the northern Great Plains, in areas with the highest amounts of precipitation, were the darkest colored and had proportionately the smallest auditory bullae. Size varied clinally in the Great Plains, with larger mice being found in the cooler, northern latitudes. Populations from the arid intermountain basins of Colorado, Utah, and Wyoming were largest in size, had the longest tails, were the palest in color, and had the largest bullae. Two races …

Redescription And Comparison Of A Highly Fossorial Mole, Domninoides Mimicus (Insectivora, Talpidae), From The Clarendonian, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

The holotype of the species, Domninoides mimicus, is based on one tooth. Described in the present report is material containing a practically complete dentition and many postcranial elements which definitely belong with the teeth. This species is closely related to Domninoides valentinensis described by Reed (1962), but some of the antemolars in valentinensis are misidentified. The tooth formulas for valentinensis and for mimicus are given. Development of the cingula on the upper and lower molars in mimicus is conspicuous. Because of similar features in the postcranial bones, the Clarendonian mole may be as fossorial as Scalopus, probably the …

Macroinvertebrate Populations In The Upper Mississippi River, David R. Mcconville

Journal of the Minnesota Academy of Science

The macroinvertebrate community of the Mississippi River near Monticell, Minnesota, was examined for 22 months. Quantitative bottom fauna information was obtained by use of concrete block artificial substrate sampling units. Representative organisms were obtained from seven (7) orders, 15 families and 35 genera of benthic macroinvertebrates. All taxa collected displayed definite seasonal trends. The Orders Trichoptera, Diptera, and Ephemeroptera were the most abundant groups collected, Trichoptera (Hydropsyche and Cheumatopsyche) were the dominant members of the benthic population in both numbers and biomass. Midges and blackflies were the dominant Diptera. Pseudocloeon, Stenonema, and Ephemerella were the most frequently collected mayflies.

Shovelnose Sturgeon (Scaphirhynchus Platorhynchus) In The Minnesota River, Paul Durkee, Brian Paulson, Robert Bellig

Journal of the Minnesota Academy of Science

The shovelnose sturgeon, Scaphirhyncus platorhyncus, according to Eddy and Underhill (1974) has not been reported from the Minnesota River for a number of years. Recently, Wilcox et. al. (1978) reported a single adult taken in 1974, and two others in 1976. Our survey of the fishes in the Minnesota River showed a substantial number of shovelnose sturgeon, at least in certain locations. Twenty specimens were taken in 42 gill net days. Other data obtained included food habits and age-length relationships. Food habits were determined through volumetric analysis of stomach contents, and ages were obtained by sectioning the marginal pectoral fin …

Comparison Of The Lens Protein Profiles Of Three Species Of Ozark Salamanders, James M. Britton

Journal of the Arkansas Academy of Science

The vertebrate lens has a high protein content (35%), 80-90% of which is composed of the soluble, lens-specific structural proteins, the crystallins. The lens protein profiles of urodelan species have been found to be qualitatively distinct. On this basis the lens proteins have been proposed as a measure of true speciation in urodelans. This paper is the result of our effort to derive a technique for comparison of lens protein profiles on a purely qualitative basis without utilizing the complex methodology employed by previous workers. With this object in mind, the lens protein profiles of Plethodon glutinosus, Ambystoma annulatum, and …

Electrophoretic Analysis Of Blood Serum Proteins In Three Species Of Water Snakes (Genus Nerodia), Phyllis J. Garnett

Journal of the Arkansas Academy of Science

Serum from three species of water snakes (Nerodia rhombifera, N. erythrogaster and N. fasciata) from one geographic region was analyzed electrophoretically on cellulose acetate, and anodic mobility and relative concentration of the fractions were determined by a recording densitometer with an automatic integrator. Classification of fractions was based on mobility (Rf, values), and for identification purposes, bands were labeled in order of decreasing mobility (albumin and alpha₁, alpha₂, alpha₃, beta₁, beta₂, gamma₁, and gamma₂ globulins). Seven fractions were identified in each species with alpha₃ being absent from N. rhombifera and N. erythrogaster, and only one gamma fraction was observed in …

Genic Variation In White-Tailed Deer From Arkansas, Phyllis K. Price, Michael E. Cartwright, Mitchell J. Rogers

Journal of the Arkansas Academy of Science

Liver and kidney samples of 33 white-tailed deer (Odocoileus virginianus) representing three populations in Arkansas were examined with horizontal starch gel electrophoresis. Of 17 loci examined, only PGM-1 and ES-2 exhibited polymorphism. Average individual heterozygosity, ranging from 2.3% to 4.7% with a mean of 3.1 %, was much lower than that reported for white-tailed deer in other parts of its range. The three populations examined in this study were highly similar based on Rogers' genetic similarity coefficient.

Notes On Seasonal Variation And Infectivity Of Haemogamasus Reidi, A Vector Of Hepatozoon Griseisciuri, On Eastern Gray Squirrels, Sciurus Carolinensis, Mohammed Bashiru

Masters Theses

Five hundred and twenty-two squirrels were trapped and retrapped from a population in Montgomery County, Maryland during 1974-1975. One hundred and forty-one squirrels were found to harbor an average of 10.6 mites (Range 175-1). While male squirrels outnumbered females (79 vs 62) females harbored more mites than males (829 vs 666). During the spring the average number of mites per captured squirrel increased to an average of 18.1 per squirrel. The average declined to 6.8, 4.8 and 3.3 per squirrel in summer, fall and winter respectively. Throughout the collection period adult female mites were by far more numerous on hosts …

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf

Nebraska Game and Parks Commission: Publications

The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …

Distribution And Ecology Of Orconectes Iowaensis Fitzpatrick And Orconectes Rusticus (Girard) In Minnesota, Gary S. Phillips, Larry A. Reis

Journal of the Minnesota Academy of Science

During 1979, a field study was conducted to determine the species of crayfish present in southern Minnesota. Specimens of Orconectes iowaensis Fitzpatrick, Orconectes rusticus (Girard), and Orconectes virilis (Hagen) were collected. These represent new state records for O. iowaensis and O. rusticus. O. iowaensis appears restricted to the Root River drainage system in extreme southeastern Minnesota. O. rusticus was found in the West Fork of the Des Moines River in southwestern Minnesota and the Cedar River drainage system in south central Minnesota. Notes on the ecology of these species are included.

Age And Huddling As Determinants Of Metabolic Rate In Grasshopper Mice (Onychomys Leucogaster), Meredith Bailey, Dennis A. Baeyens, Lana Mann

Journal of the Arkansas Academy of Science

The metabolic rates of grasshopper mice (Onychomys leucogaster) were determined every third day from birth to adulthood. Metabolic rates were quantitated by measuring oxygen consumption in an open circuit system. There was a rapid fall in oxygen consumption from the third day after birth until the ninth day. Mice which were housed separately assumed a constant metabolic rate at an earlier age than mice which were kept with litter-mates. The greatest increases in metabolism occurred when immature mice were separated from litter-mates for oxygen consumption determinations. It is concluded that huddling plays an important role in reducing the metabolic rate …

Maturation And Fecundity Of Redear Sunfish, James C. Adams, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Based on gonosomatic indices and ovum diameter frequency distributions, the redear sunfish spawns from May through July. Fast growing 2-year-old (above 150 mm) and older fish attain sexual maturity. Mature ovum diameter ranged from 0.60 to 1.30 mm. Fecundity • total length, • total weight, and • age relationships were: 1nF = 5.95242 + 0.01967L (r²= 0.90), LnF = 8.80328 + 0.00594W (r²= 0.92), and 1nF = 8.19332 + 0.50231 A (r² =0.83), respectively.

Effect Of Turf Fungicides On Earthworms, J. H. Roark, J. L. Dale

Journal of the Arkansas Academy of Science

Numerous turf fungicides were tested under various conditions for possible deleterious effects upon the earthworm Eisenla foetida. Earthworms treated by immersion for one minute in 0.1% solutions of 10 different fungicides died insignificant numbers after benomyl and thiophanate methyl treatments. After 1% fungicide treatments, there was significant mortality from benomyl, ethazole, Kromad, and thiophanate methyl fungicides. With 2% fungicide solutions, significant numbers died after benomyl, cadmium succinate, ethazole, thiophanate methyl, and thiram treatments. Earthworms fed bermudagrass clippings treated with 10 different fungicides showed a significant decrease in longevity from clippings treated with benomyl, dinocap, ethazole, and thiophanate methyl. Earthworms reared …
