Pollution And Evolution, David J. Merrell

Journal of the Minnesota Academy of Science

Three examples, industrial melanism in moths, insecticide resistance in insects, and myxomatosis in Australian rabbits, are used to illustrate the concept that evolution may result from tampering with the physical or biotic environment of a species. Hence, concern about the effects of pollution must encompass not only the possibility of extinction but the possibility of evolution. In the case of harmful species, biological or chemical control measures may result in populations more refractory to control than the original untreated populations.

Myxobacterial Columns, Walter Fluegel

Journal of the Minnesota Academy of Science

The soil myxobacterium, Myxococcus fulvus, will produce clavate columns of slime and cells in certain static liquid cultures. The cells protrude from the thicker end of the column like pins in a pincushion. The column's distribution is in an even array. An hypothesis is suggested for the origin of these formations. The columns are not fruiting bodies. Column formation in other fruiting myxobacteria suggests that it is not a unique feature. Only one other fruiting myxobacterium which produced columns has been reported, and that more than two decades ago.

Protein Patterns Of Dragonfly Hemolymph As Shown By Gel Disc Electrophoresis, Myron Anderson, Lee Halgren, Louis Nuti

Journal of the Minnesota Academy of Science

Acrylamide gel disc electrophoresis of the hemolymph of nymphs of the families Libellulidae and Aeschnidae showed a difference in the mobility of their protein components. Simultaneous comparisons of Anax iunius, Aeschna umbrosa, and Libellula pulchella gave clear separation of the species. Changes in protein composition associated with stage of nymphal development and transition from nymph to adult were apparent.

Mayfly Cholinesterase: Solubilization And Partial Purification, Burton C. Lidgerding, Donald J. Kraft

Journal of the Minnesota Academy of Science

A method hos been developed for the solubilization of cholinesterase from whole mayflies (Hexagenia bilineata, Soy). Solubilization is enhanced through the use of: (1) protamine sulfate, (2) sephadex, (3) sodium taurocholate, and (4) ammonium sulfate-sodium bicarbonate treatments. Partial purification of the enzyme is also reported. Fractions representing a final activity of 246 units and a purification factor of 17.79 are presented.

Anabaenopsis Raciborskii Woloszynska In Minnesota Lakes, Hibbert Hill

Journal of the Minnesota Academy of Science

Anabaenopsis Raciborskii Woloszynska has been observed in Lakes near Minneapolis, Minnesota, during the period 1966-1969. The variations found are described. This alga has not previously been described from the Great Lakes States.

Rest Site Selection By Radio-Tagged Raccoons, Jay H. Schnell

Journal of the Minnesota Academy of Science

Daytime resting sites and behavior of 14 radio-tagged raccoons were studied from April 18 to November 27, 1965, with types and use of the sites, daytime activity and shifts at the sites, and approach movements previous to resting being analyzed. The radio system pinpointed 173 rest sites, 7 4 per cent in swamps, 17 per cent in hollow trees, and 9 per cent in squirrel or bird nests. Use of the rest sites did not correlate with habitat type or size of the home range or with distances which animals traveled during their active nightly period. Behavioral influences in selection …

Waterfowl Production In A Selected Wetland Management Area, Orlo A. Quame, Alfred H. Grewe Jr.

Journal of the Minnesota Academy of Science

This study of a Type 5 Federal Wetland Management Area showed that: (1) production (young remaining on the area to flight stage) in birds per acre was 0.74 in 1967 and 0.57 in 1968; (2) the greatest temporary use of the area was mode by blue-winged teal, 64 being sighted at one time; and (3) artificial loafing structures may increase use of a wetland by breeding ducks.

Germinability Factors Of Field-Grown Sorghum Seed, D. B. Sauer, C. M. Christensen

Journal of the Minnesota Academy of Science

Germination of sorghum seed did not appear to be affected by spraying the plants with Maneb or with a chemical defoliant before harvest. Mechanical threshing greatly reduced germination of most but not all lots; this injury is thought to be related to the maturity and/ or moisture content of the seed when threshed, although other varietal differences may be important. At any given time there were large differences in moisture content between seeds of different hybrids, different plants of any one hybrid, and between different parts of the same panicle.

Lead Absorption From Soil Into Legumes, Marie H. Berg

Journal of the Minnesota Academy of Science

There is evidence that lead is taken up from the soil into legumes and accumulated in the leaves of beans and peanuts which were examined in this study.

Lead-Poisoning From Environmental Contamination, A. Karim Ahmed, George Bloom, Clifford A. Ottaway

Journal of the Minnesota Academy of Science

Geochemical studies demonstrate large-scale increases of lead in the general environment. A principal source of this contamination has been traced to the use of tetraethyl lead in gasoline. It is not clear at the present whether these increased levels of lead cause chronic insult to the general population. On the other hand, lead poisoning in young children because of lead based paint flakes in deteriorating housing has been well-documented in many inner-city areas. Between 5 and 10 percent of children (between the ages of one and six) living in sub-standard housing in Chicago, Cleveland, and Baltimore show symptoms of lead-poisoning. …

The Influence Of Information Signs On Visitor Distribution And Use, Perry J. Brown, John D. Hunt

Forest Management Faculty Publications

Lack of information is a primary factor accounting for visitors jamming recreation sites, overflowing onto highway rights-of-way and blocking facilities [5, p. 95]. In attempting to attain an even distribution of visitors, the importance of information signing as a management tool is often overlooked. Oxenfeldt indicates that advertising (information) alters behavior most efficiently when it supplies information customers are seeking [4, p. 471]. Tocher and Kearns noted in visitor characteristic studies that travelers seek different experiences when touring than when at home or work [6]. Information signs may lead the visitor to these different experiences. Hypothesizing that signs can influence …

"Roseburg Area 'Ideal' For Growth Of Wine Industry" Article, The News-Review

Studies On The Helminth Fauna Of Alaska, Xlvi. Davainea Lagopodis Sp. Nov. (Cestoda: Davaineidae) From Grouse (Tetraonidae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Cestodes of the genus Davainea Blanchard 1891, from grouse in various Eurasian and North American regions have been identified as D. tetraoensis Fuhrmann 1919, or less frequently as D. proglottina (Davaine 1860). Those from ptarmigan (Lagopus spp.) in Alaska, resembling D. tetraoensis in some details but having only a single row of rostellar hooks and fewer testes, were earlier reported as D. proglottina by Babero (1953). The study of additional material from grouse from Alaska indicates that this cestode is specifically distinct from the two species mentioned. It is described here as new.

The Nature Of The "Contractile" Protein Isolated From Brain / S. Puszkin, E. Puszkin, D. D. Clarke, And S. Berl. Coll Of Phys. And Surgeons., Columbia Univ., N.Y. 10032, S. Puszkin, E. Puszkin, Donald Dudley Clarke Phd, Soll Berl

Chemistry Faculty Publications

We have described the isolation from brain of a Mg++/Ca++-ATPase resembling muscle actomyosin (Sci. 12 1 1701 1968). Like myofibrils (Perry and Grey 1 Biochem. J. 64, 184, 1956), the ATPase activity isolated from rat and cat brain is dependent upon the cone. of ATP and cation. When the conc. of ATP exceeds that of Mg++ 1 enzyme activity is inhibited. With increasing conc. of Mg++ 1 the optimum conc. of ATP also increases. This does not occur with Ca++ . Polyethylenesulfonate( PS)(I0-6M)causes the splitting of actomyosin into actin and myosin; the Mg++-ATPose activity is correspondingly diminished (Barony and Joisle …

The Dissociative Breakdown Of Negative Ions / By D. D. Clarke, Chemistry Department, Fordham University, New York, 10458, U.S.A. C. A. Coulson, Mathematical Institute, University Of Oxford, Donald Dudley Clarke Phd, C. A. Coulson

Chemistry Faculty Publications

A discussion is given of the process whereby a substituted aromatic molecule captures a slow electron and dissociates. It is shown that the process often goes via two stages. and that the relative symmetries of the electroncapture state and the final dissociation state are very important. Both the sensitivity of the process to changes in the substituent and the existence of an activation energy are explained in the model

Studies in vivo and in vitro of the distribution of label in C-1 of glutamate and glutamine and C-4 of aspartate in the free amino acids of brain were carried out. [1-14C]Acetate was used both in vivo and in vitro and L-[U-14C]aspartate and L-[U-14C]glutamate were used in vitro. (1) The results obtained with labelled acetate and aspartate suggest that CO2 and a 3-carbon acid may exchange at different rates on a CO2-fixing enzyme. (2) The apparent cycling times of both glutamate and glutamine show fast components measured in minutes and slow components measured in hours. (3) With [l-14C]acetate in vitro …

A Discussion Of The Cytherinae (Ostracoda) With Description Of Two New Species, Leslie Edward Watling

University of the Pacific Theses and Dissertations

This paper is concerned with the description of two new ostracod species, and the discussion of their affinities with other species in the subfamily Cytherinae. In this discussion reference is made to the morphological features of several genera. At this point it must be made clear that although the original type descriptions were used, the author has never seen the type specimens. Thus, all discussion is based on these original descriptions as well as on available supplementary material.

A Study Of The Effects Of Sitosterol Ingestion On The Serum Cholesterol Concentrations Of Two Genetically Different Strains Of Laboratory Mice, Marie Nichols Goldberg

University of the Pacific Theses and Dissertations

A possible interrelationship between serum cholesterol level and atherosclerosis has long interested investigators in the fields of physiology and biochemistry. Cholesterol is found in very high concentrations in the plaques that occlude coronary arteries in man and laboratory animals. It is generally agreed that hypercholesterolemia favors the appearance of atherosclerotic lesions.^1<1

In recent years, much information has been accumulated regarding the factors which affect the serum cholesterol level. Exact and detailed biochemical mechanisms are still not clearly understood. However, it has been demonstrated that the serum cholesterol levels of man and several experimental animals can be lowered significantly by …
