A New Species of Eleodes from Texas, with Notes on the Subgenus Promus (Coleoptera: Tenebrionidae)
(1971-01) Triplehorn, Charles A.
A new species, Eleodes (Promus) knullorum, from Texas is described and two names for taxa in the subgenus Promus are placed in synonymy, E. seriata LeConte under E. goryi Solier and E. terricola Blaisdell under E. insularis Linell.

The Relationship Between Soil pH and Base-Saturation Percentage for Surface and Subsoil Horizons of Selected Mollisols, Alfisols, and Ultisols in Ohio
(1971-01) Beery, Maynard; Wilding, L. P.
In the 7th Approximation soil classification system, base-saturation percentage is used as a definitive criterion in separating Alfisols (Gray-Brown Podzolics) from Ultisols (Red-Yellow Podzolics) and Umbric epipedons (acidic, dark-colored surface horizons) from Mollic epipedons (other dark-colored surface horizons). Ohio soil scientists are currently using field-determined pH to estimate base-saturation percentage when laboratory data are unavailable. To test the reliability of this estimation, soil pH was measured in water and in KC1 for three horizons (Ap, Bl, and B2) for 64 soils comprising three soil orders in Ohio—Mollisols (Humic Gleys), Alfisols, and Ultisols. Linear regression analysis was used to correlate pH in KC1 with pH in water, and base-saturation percentage with both pH in water and KC1. Soil pH in KC1 was highly correlated (r = 0.897 to 0.984) with pH in water, and pH in KC1 can be accurately predicted from simple regression equations. It is about one unit lower than the pH value in water. There is a closer relationship between base-saturation percentage and pH measure in water (r = 0.668 to 0.928) versus that measured in KC1. Soil pH measured in water correlates more closely with base-saturation percentage for Ap horizons (r=.838 to .928) than for subsoil horizons (r=.668 to .801). For all horizons of Mollisols, and Ap horizons of both Alfisols and Ultisols, relatively smaller amounts of H+ are released from the exchange complex by addiction of KC1 to the soil suspension.
Amino Acids in the Haemolymph of Smaller European Elm Bark Beetle Larvae, Scolytus Multistriatus (Marsham) (Coleoptera: Scolytidae)
(1971-01) Kleiner, Gail F.; Peacock, John W.
Nineteen amino acids and two amides were detected in the haemolymph of last-instar Scolytus multistriatus larvae by thin-layer chromatography. Glycine, arginine, glutamine, lysine, ornithine, histidine, asparagine, glutamic acid, serine, proline, alanine, valine, isoleucine, and leucine were readily detected. Taurine, phenylalanine, tyrosine, a- and B- amino butyric acid, and aspartic acid were less readily detected on some chromatograms, and at times were apparently absent in the haemolymph extract. Cysteine, cystine, and cysteic acid were not adequately separated by any of the methods tried, but their presence was confirmed through co-chromatography.
A Description of the Complete Metamorphosis of the Sea Urchin Lytechinus Variegatus Cultured in Synthetic Sea Water
(1971-01) Mazur, Jane E.; Miller, John W.
The urchin Lytechinus variegatus was cultured through metamorphosis, from eggs and sperm collected from mature forms, in synthetic sea water, in the laboratory. A unicellular green alga was used as the nutritional source. A description and photographic record are presented of the complete development from fertilized egg to adult.
The Effect of Simazine, Kinetin, and Rhizobium Phaesoli on Legume Nodulation and Morphogenesis in Phaseolus Vularis L., cv. "Red Kidney"
(1971-01) Thomas, Martha A.; Hammond, H. David
The growth responses of Phaseolus vulgaris L., cv. "Red Kidney" plants to simazine at 5 x 10~5M and 5 x 10^6M, kinetin at 9 x 10~7M and 9 x 10~8M, and the presence or absence of Rhizobium phaseoli ATCC14482, in factorial combination, were measured. The plants were analyzed with respect to the lengths of the primary-through-quaternary leaves, stem height, fresh and dry weights, number of flowers, and number and size of nodules. An analysis of variance showed that simazine significantly depressed all parameters at both concentrations. Kinetin did not affect the lengths of the primary-through-tertiary leaves, but depressed the quaternary, and also decreased dry weights at the higher concentration. Kinetin had no effect on stem height; it decreased flowering, but enhanced modulation. The presence of Rhizobium had a significant effect only on flowering and nodulation, increasing both.
Leeches Found on Two Species of Helisoma from Fleming's Creek, Michigan
(1971-01) Sarah, Hugh H.
A survey of leeches in three genera of gastropods collected from Fleming's Creek, near Ypsilanti, Michigan, revealed a selective association between the smaller leech Helobdella papillata and the smaller snail, Helisoma anceps, and between the larger leech Helobdella lineata and the larger snail Helisoma trivolvis. In addition, a few individuals of the leech Glossiphonia complanata were found on both helisomid snails, and this species, together with nine other species of leeches, was also found either free-swimming or attached to substrate other than one of these snails.
Distribution of Naturalized Carduus Nutans (Compositae) Mapped in Relation to Geology in Northwestern Ohio
(1971-01) Stuckey, Ronald L.; Forsyth, Jane L.
Within recent years the nodding thistle or musk thistle (Carduus nutans L.) has become naturalized and abundant in northwestern Ohio in at least two areas, the Castalia- Bellevue-Sandusky area and the Carey area. In the summers of 1967 and 1968, the total detailed distribution of Carduus nutans in these two areas was mapped by noting its occurrence and abundance in relation to the general geologic conditions, topographic features, and habitats. The thistle was most abundant in moderately grazed pasture fields, hay fields, and along grassy roadsides on high, dry ridges and hillsides where the limestone or dolomite bedrock was less than six feet below the surface. Plants were rare or infrequent where the bedrock was deeper, in flatter terrain, in cultivated fields, and along railroad tracks. Detailed maps of the two areas depict, by the use of three different sizes of dots, the aproximate abundance of the plants at each site and the correlation of this distribution with the geologic substrate. Expansion of the plant's local range by natural means is slow, because many of the heads do not have fully developed achenes, the achenes do not readily become separated from the head, and the heads tend to drop to the ground directly beneath the parent plant. These data, although limited, may allow botanists to predict locations where Carduus nutans might be expected to invade in the future, and geologists to infer, from reported occurrences of the plant in Ohio, the presence of limestone or dolomite bedrock at shallow depths.
