The more important members of this population were members of the Fungi Imperfecti, 25% of these yeast like and the remainder filamentous fungi. Species with phialidic conidium production represented 80% of the filamentous fungi. Larger numbers of species and colonies were recovered during the mid-autumn sampling period.

Scanning electron microscopic observation of blood samples before, during and after cardiopulmonary bypass during cardiovascular surgery revealed that 4 to 25% of the red blood cells undergo a progressive transformation of discocyte to echinocyte. A morphological index, I, was developed and the change in I (Ir) was found to correlate well with measurements of free plasma hemoglobin. Incubation of blood samples form normal subjects for 90 minutes at 37°C resulted in no increase in Ir whereas incubated samples from patients following cardiopulmonary bypass showed an increased Ir to a mean value of 1140 ±185. Incubation therefore appears to uncover sublethal red cell damage caused by extracorporeal circulation. It is suggested that this technique is a sensitive index of red cell trauma which may have useful clinical applications.

Chitinozoa from the Middle Devonian Columbus Limestone of central Ohio belong to eight species of the genera Alpenachitina, Ancyrochitina, Angochitina, Conochitina, Desmochitina, and Eisenackitina. Two new species, Ancyrochitina frankeli and Eisenackitina robusta, are described. The Chitinozoa occur in carbonate rocks such as mudstone, grainstone and packstone that represent well circulated open marine conditions. They are absent from dolomite which represents sediment deposited at a shallow water depositional site characterized by restricted water circulation. Comparison of the Columbus Limestone Chitinozoa with faunas from similar Middle Devonian strata in Iowa, Illinois, and Missouri indicates that the Middle Devonian Wabash Platform, located in Indiana, effectively restricted the distribution of chitinozoans in the Illinois and Appalachian Basins.

Gross beta and mCs radioactivity levels were determined for pectoralis muscle of resident Canada geese (Branta canadensis) in 3 wildlife areas in Ohio. The mean mCs level was 0.9 dpm/g dry wt muscle (0.4 pCi/g), and the mean gross beta level was 20.4 dpm/g dry wt muscle (9.2 pCi/g). No differences in goose muscle radioactivity levels were observed among the 3 wildlife areas. Bird age apparently did not affect radioactivity level. Variance components between and within birds were computed and a sampling design, to optimize allocation of resources for future sampling schemes, was determined.

Distribution, Phenology and Biomass in an Oak-Hickory Forest Eichenberger, M. D.; Parker, G. R. Studies of the distribution, phenology, and biomass of goldenseal (Hydrastis canadensis L.), a rare medicinal plant of the northeastern United States, were begun in 1973 in Bryan Nature Preserve, where the species is abundant. Individuals were found in distinct clumps which were aggregated with the greatest concentration occurring in the northwest corner of the forest. Goldenseal matured during canopy closure and remained throughout the growing season. It was found in greater numbers in the interior area of the woods rather than on the edges. Goldenseal emerged in mid- to late April and flowered between April 20 and May 10. Each mature individual flowered, although some flowers never opened. The density of aboveground stems decreased between June and September, with th.2 greatest attrition occurring among immature individuals. Leaf expansion occurred primarily after flowering and during development of the overstory leaf canopy. Fruit enlargement followed the initial rapid development of the leaves. During this time, leaf expansion was depressed. Fruits matured from late June to late July. Above-ground biomass reached a peak by mid-July and then declined with senescence of plants until the first killing frost. Greater than 95% of the above-ground biomass was produced within the first month of the growing season. There was at least a 20% sloughing of roots during the dormant season. Estimates of total biomass per clump show an increase of 24% in both edge and interior clumps between 1973 and 1974. Although the total increase was the same in both areas, the interior clump biomass increased because of an increase in the proportion of larger individuals, while the greater edge clump biomass was due to new individuals.

Daily nights between roosting and feeding areas occurred in many directions and only the net movements were north in the spring and south in the fall. Each year the spring movements started between March 1 to 17 and ended between May 5 to 23 with an average period of G5 days. Fall migration usually occurred in October and November. Patterns of flight roosting and feeding appeared to change wThen small flocks united with larger flocks. Canada may provide late-summer and early-fall feeding places for blackbirds nesting in northern Ohio.
