Does a Soil Acidity Test as Used in Soil Testing Laboratories Determine our Calcium Need in Ohio Soil
(1965-07) Tiedjens, V. A.
Soil samples from many sections of the United States and Canada show a paucity of available calcium even though the pH reading seems satisfactory. Studies made on these soils show that the pH test, accurate for most purposes, does not indicate the available calcium in the presence of other fertilizer ions. A high pH does not necessarily indicate adequate calcium in the soil.
Contribution of Soils to the Mapping and Interpretation of Wisconsin Tills in Western Ohio
(1965-07) Forsyth, Jane L.
Soils have been an important tool in the interpretation of the Wisconsin glacial history of western Ohio. Five different tills are recognized in this area, identified by five different soils, which are distinquished on the basis of (1) presence or absence of silt (loess) cap, (2) amount of clay in B horizon, (3) amount of clay in C horizon, and (4) depth of soil profile. Where the critical difference between two adjacent soils relates to one of the first three factors, composition is considered to be the explanation; where the difference is based on the fourth factor, one soil appearing to be deeper and more weathered than the other, a difference in age between the tills is inferred, the younger till interpreted to represent the deposit made during a major readvance of the retreating glacier. Careful evaluation of the differences between each set of adjacent soils reveals the following Wisconsin glacial history: after the very long Sangamon Interglacial, the "early" Wisconsin glacier appeared, only locally extending beyond the limits of younger deposits, followed, after a moderately long ice-free period, by the "late" Wisconsin glacier. During recession, this last glacier deposited a series of end moraines, with a major readvance (judged by soils differences) marked by the Farmersville-Reesville Moraines, and a less significant readvance marked by the Union City-Powell Moraines. The retreat preceding this last readvance must have extended north of the Ohio divide, allowing formation of an ice-front lake in which clay could accumulate, for the till subsequently deposited is rich in clay.

A New Species of Anchastus (Coleoptera: Elateridae)
(1965-07) Knull, Josef N.
An interesting click beetle, attracted to a 15-watt General Electric blacklight in Columbus was collected and has been named Anchastus splendidus sp. n.
Ploidy of Some Non-Spherical Nuclei in Cockroaches Calculate from Photometrically Measured DNA Content
(1965-07) Wilson, Louis F.
A modified photometric technique for measuring the DNA content in nuclei was devised to estimate the degree of ploidy in the large flattened (oblate spheroidal) nuclei of the male accessory gland in the American cockroach, F eriplaneta americana (L.), and the German cockroach, Plattella germanica (L.). This technique involves measuring diameters of the nuclei as well as light transmission through the nuclei in two dimensions rather than one as with spherical nuclei. The measurements are then combined to form an "average nucleus." Regular photometric methods were employed on the haploid spermatid used as the standard for comparison. The modified technique produced DNA values that were nearly perfect multiples of the standard. The calculations revealed 16-ploid and 32-ploid nuclei in P. americana and 8-ploid and 16-ploid nuclei in B. germanica.
Diplocardia Gatesi, A New Earthworm from North Carolina (Oligochaeta: Megascolecidae)
(1965-07) Murchie, William R.
A new species of earthworm, Diplocardia gatesi is described from the southern mountainous regions of the eastern United States. This earthworm is morphologically similar to D. udei; with minute prostatic setae, hastate spermathecal setae, quadrithecate condition, and dorsal vessel single anteriorly. The internal calciferous gland lamellae are free. It differs from udei in the structure of the spermathecae and the structure and arrangement of the male field.
A Modified Tri-Basic-Dye Technique for Neuroglia in Autonomic Ganglia
(1965-07) Hall, James L.; Schwyn, Robert C.
A specific Tri-Basic-Dye staining technique has been developed for demonstrating neuroglia nuclei in autonomic ganglia. Criteria used for development of this technique was simplicity, specificity, minimum time consumption, paraffin sections, and good photographic qualities. Modifications of a Tri-Basic-Dye procedure, originally reported by Spoerri (1948) for nerve cells and Nissl granules, have elicited a greater differentiation of neuroglia nuclei and greater intensity of their granular pattern. Neuroglia cells are readily distinguishable and well differentiated in the presence of nerve cells and Schwann cells. This technique is recommended for all investigators interested in a simple, rapid, and excellent technique for demonstrating neuroglia nuclei and their relationship to other structures in the autonomic and peripheral nervous system.

The Annual Distribution and Stratification of Phytoplankton at Aurora Lake, Portage County, Ohio
(1965-07) Marshall, Harold G.
A 13-month study of a hard-water lake in northeast Ohio has provided a quantitative and qualitative record of the seasonal changes of the phytoplankton. Maximum production occurred during the summer and winter periods. The summer pulse was dominated by the cyanophyte species: Microcystis aeruginosa, Anabaena spiroides, A. circinalis, and A phanizomenon flos-aquae. The dominants of the winter pulse were the diatoms Fragilaria crotonensis and Asterionella formosa, which formed separate peaks under an ice cover in December and January, respectively. The January development extended into March with the highest concentrations for the year being reached at approximately 1,400,000 cells per liter. The Chlorophyta were represented by 34 species, but quantitatively were of minor importance. The Pyrrophyta were uncommon and were represented by only 3 species. Periods of maximum and minimum phytoplankton development correspond closely in duration and magnitude at the surface and at one meter, with a slight tendency for pulses at two meters to lag behind. Vertical distribution indicated that the cyanophyte species, Phacus sp., and Fragilaria crotonensis were more numerous in the upper layers, whereas Asterionella formosa, Synedra sp., Closterium sp., and Melosira granulata occurred in greater numbers in the lower strata. Microcystis aeruginosa was noted to change its level of greatest concentration with the seasons.
The Synthesis of 2,7-Dimethylphenanthrene
(1965-07) Newman, Melvin S.; Zeelen, P.
The synthesis of 2,7-dimethylphenanthrene from dimethyl 4,4'-dimethyldiphenate is described. The ester groups were reduced to hydroxymethyl groups and the latter converted to bromomethyl groups. Cyclization of the latter with phenyllithium followed by dehydrogenation of the product over palladium-on-charcoal afforded 2,7-dimethylphenanthrene.
The Meaning of the Maxwell Field Equations
(1965-07) Holm, Gustave R.
The objective here is to emphasize the derivation of the electromagnetic field equations from simple, understandable physical considerations, instead of regarding them as arbitrary assumptions. The factors of symmetry, continuity, and propagation determine these equations. These are large-scale attributes of field structure, so we can readily recognize and accept the fact that small-scale structure involves additional factors which do not appear in these equations.
Distribution and Abundance of the Polychaete, Manayunkia Speciosa Leidy, in Western Lake Erie
(1965-07) Hiltunen, Jarl K.
The abundance and distribution of the freshwater polychaete, Manayunkia speciosa, in 1961, are described for western Lake Erie. Previous records reveal that the species has either been generally overlooked or presently its numbers have greatly increased in the area considered.
A Comparison of Photosynthetic Yields in the Maumee River, Steidtmann's Pond, and Urschel's Quarry under Natural Conditions
(1965-07) Hufford, Terry L.
A study of photosynthetic rates under natural conditions in the Maumee River, Steidtmann's Pond, and Urschel's Quarry, computed from pH and O2 measurements in the natural habitat at 4- to 6-hr intervals, revealed average rates of 1.4 to 20.9 /xmol CO2 absorbed petliter of water per hour, and 0.27 to 1.32 ^mol CO2 absorbed per /xliter of plant matter per hour, with 0.1 to 35.0 /imol O2 evolved per liter of water per hour, and about 0.012 to 2.22 yumol O2 evolved per pliter of plant matter per hour. These values lie within the range of values for ponds, quarries, lakes, and streams reported in the literature. They are much lower than published values for clear flowing streams. It seems likely that poor light supplies resulting from suspended silt particles cancel any ecological advantage the turbulence of flowing water might provide. The ratios of O2 production to CO2 absorption were close to unity except during the spring flood period when ratios below 0.1 were observed, similar to ratios found in a shallow pond near Bowling Green.
