A Statistical Analysis of Blackbird Aggressiveness
(1969-01) Burtt, Harold E.; Giltz, Maurice L.
scale with a reliability of 0.82 was developed for rating an avian behavior pattern tentatively identified as aggressiveness. The scale was applied to wild birds held in the hand and threatened in a standardized fashion. Individual differences in aggressiveness were demonstrated for Brown-headed Cowbirds and Common Grackles. Correlation between two ratings of the same bird was 0.53 for Grackles and 0.79 for Cowbirds. The most aggressive species of those studied were Grackles and Cowbirds and the least aggressive were Red-winged Blackbirds and Starlings
Ligand Field Spectra in Metaphosphate Glasses
(1969-01) Dingledy, David P.; Cowen, Charles A.
The ligand field absorption spectra in the ultraviolet, visible, and near-infrared regions of metaphosphate glasses containing the first-row (3d) transition elements, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu, were compared with spectra for the same elements in aqueous orthophosphate solution. In general, the positions of the glass ligand field absorption bands correspond to those of the solution, indicating that the transition element species in glass is coordinated in a similar manner to that of the same element ion complexed in the aqueous solution. Furthermore, when an effort is made to keep the surroundings of the transition metal species similar in glass and in aqueous solution, as in the present work, the ligand field spectra do not differ greatly. Variations from these similarities are discussed.
Observations on the Parasites (Hymenoptera, Diptera) of Trichotaphe Levisella Fyles (Gelechiidae, Lepidoptera) with Notes on the Host
(1969-01) Balduf, W. V.
Caterpillars of the aster leaf-tier moth (Trichotaphe levisella), believed to winter in the duff under the mats of aster leaves, in May tie the vegetative leaves of Aster macrophyllus Linn, in northeastern Minnesota. Sixteen species of hymenopterous parasites and one tachinid fly were observed in caterpillars and chrysalises of this species at Eaglenest Lakes, Minnesota, in 1962-1965. Based on differences in host-parasite relations, there are six categories of the parasites as characterized and exemplified below. 1. Primary, solitary, and endogenic larval parasites in the caterpillar: Braconidae, Meteorus dimidiatus (Cresson), Orgilus indagator Muesebeck; Ichneumonidae, Pimplopterus marginatus (Provancher), P. sp. near parvus (Cresson), P. sp., Temelucha sp. near epagoges (Cushman), Scambus pterophori (Ashmead), Campoplex sp.; and Tachinidae, Lixophaga sp. 2. Primary, gregarious, ectogenic larval parasites on the caterpillar: Braconidae, Oncophanes pusillus Muesebeck. 3. Double-role parasites: as primary, solitary, endoparasites in the caterpillar; and as secondary, solitary, parasites in cocoons of Temelucha sp. near epagoges: Ichneumonidae, Scambus tecumseh Viereck. 4. Primary, solitary, endogenic larvae in the chrysalises: Ichneumonidae, Phaeogenes sp. 5. Secondary, solitary, endogenic larvae in cocoons of primary parasites of the caterpillar: Ichneumonidae, Pimpla sp., in cocoons of Temelucha sp. near epagoges; Gelis spp., in cocoons of T. sp. near epagoges and of Meteorus dimidiatus; Pteromalidae, Catolaccus cyanoideus Burks, in cocoons of T. sp. near epagoges. 6. Secondary, gregarious, endogenic larva in cocoons of primary parasites of the caterpillar: Eulophidae, Pediobius sexdentatus (Girault), in cocoons of Temelucha sp. near epagoges and of Pimplopterus sp.; Dimmockia pallipes Muesebeck, in cocoons of M. dimidiatus, Temelucha sp. near epagoges, P. marginatus, and P . sp. near parvus
A Small Late Woodland Hearth Near Pioneer, Ohio
(1969-01) Forsyth, Jane L.
A small prehistoric hearth, located 1 1/2 miles southwest of Pioneer, in Williams County, Ohio, was excavated on October 5, 1967, by a group of soils scientists, while on a field conference. The hearth, two to three feet across by about two feet deep, yielded some fragments of charcoal (Quercus), a few wood snails (Mesodon inflectus), small broken mammal bones (Blarina brevicauda, Indian dog, and turtle-carapace scraper), and a few pottery sherds. No projectile points were found, either in the filling of the hearth depression nor on the surface of the adjacent plowed field, although chert chips were present in the field. A diorite hammers tone was also recovered from the field. Most informative in terms of dating the site was the pottery, despite its small and fragmentary nature. Two different specialists (R. S. Baby and D. W. Dragoo), working independently, both identified the hearth occupation, on the basis of the pottery, as Late Woodland (Cole Culture), dated at approximately 900-1100 years A.D.
Studies with 60Co-Radiated Guar (Cyamopsis Tetragonoloba) (L.) Taub
(1969-01) Vig, Baldev K.
Dry seeds of G-II (bushy, fodder type) and G-IV (erect, pod type) varieties of Punjab guar {Cyamopsis tetragonoloba) were radiated with gamma rays using 60Co as source of radiation. The doses applied were 5,000, 10,000, 20,000, and 30,000 r. The radiation speeded up germination, increased the rate of root growth, and expanded the range of plant height and stem girth in the generation from the radiated seeds (Ri). Other morphological variants in Ri were: Chlorophyll defects, small-leaved and small-poded types, unusually tall and unusually small plants, and chimaeras for pod and leaf size. In R2 none of the above characters excepting chlorophyll defects appeared, thus establishing that non-genetic changes were responsible for other variations. In R2 and R3, however, segregation was observed for plant height and branching from both G-II and G-IV. In no case were the number of genes involved determined.
