Vegetative Reproduction in Populations of Justicia Americana in Ohio and Alabama
(1980-05) Lewis, Kenneth P.
Community structure and the role of vegetative reproduction were studied in the essentially monotypic stands of water willow within the Scioto and Hocking Rivers of Ohio and the Flint and Paint Rock Rivers of Alabama. Vegetative reproduction in both Ohio and Alabama populations was most successful with rhizome portions, if the sections were subject to soil deposition. If soil deposition over the sections was not involved, then upright stem sections were most successful. Total darkness is inhibitory to vegetation reproduction, and reproduction is significantly less under a 500 lux light regime as compared to that under 5,000 or 20,000 lux. Vegetative reproduction is not increased by free floating, as might occur during flooding.
Vegetative Structure of an Essentially Undisturbed Beech-Maple Ecosystem in Central Ohio
(1980-05) Gilbert, Gareth E.; Riemenschneider, Victor L.
All woody stems >2.5 cm diameter at breast height (dbh) occurring within 1 ha of an essentially undisturbed beech-maple ecosystem of central Ohio were inventoried for species, vegetative level,and dbh, and values were derived for mean area, density, dominance (basal area) and frequency. Species importance values (sum of relative density, relative dominance and relative frequency) were also calculated. The total number of individuals occurring with the 1 ha sample area was 1456 of which 15%, 73%, 6% and 6% occurred in the shrub, smalltree, subcanopy and canopy vegetative levels, respectively. Total basal area of all individuals was 32.7 m2 of which the shrub, smalltree, subcanopy and canopy levels contributed approximately 1%, 7%, 20% and 72%, respectively. Fagus grandifolia and Acer saccharum had the greatest species importance values for each of the vegetative levels (values for the shrub level were not calculated) and the value of the former for all individuals >2.5 cm dbh was greater than the latter by a factor of about 2.

Preliminary Observations on a New Trait, Opposite First Compound Leaf, in Glycine Max, (Soybean)
(1980-05) Evans, D. A.; Paddock, Elton F.
A new trait in Strain T219 of Glycine max (L.) Merrill, opposite first compound leaves (Opp) followed by alternate subsequent compound leaves as opposed to the usual exclusively alternate compound leaves (NOpp) was found. This strain segregated in a 1:2:1 ratio for dark green: light green: yellow at the yn locus. In the original sowing of 371 seeds, a 3:1 ratio of NOpp: Opp was observed. Following 4 generations of selection in which only Opps from the seed source with the highest frequency of Opp were raised to maturity, the frequency of Opp decreased from 42% Opp in the PI generation to 2.2% Opp in the S4 generation. In a parallel selection with the same material, against Opp, the frequency of Opp consistently decreased from 25 to 0%. Water at 47 °C applies to dormant seeds for 2 hr before sowing modified dormant, but seed storage for 2 years had no noticeable effect on, the frequency of Opp.

Comparison of Zooplankton Found in the Eastern Basin of Lake Erie in 1928 and 1974
(1980-05) Cap, Roberta K.
Crustacean zooplankton from Eastern Lake Erie collected in 1974 were compared with those found in a 1928 survey. Calanoid copepods composed a higher percentage of the total zooplankton community in 1928, whereas cyclopoids were the more important component in 1974. Nine taxa of copepods and 9 taxa of cladocerans were observed in 1928. In 1974, 8 species of copepods and 11 species of cladocera were found. Oligotrophic indicator organisms (e.g. Limnocalanus macrurus) were more common in 1928, while eutrophic indicators (e.g. Diaptomus siciloides) were more common in 1974. The relative abundances of organisms occurring in both years were very different. Leptodora kindtii occurred in 55% of the samples in 1928 but only in 22% in 1974. Daphnia retrocurva occurred in 12% of the 1928 samples but in 90% of the 1974 samples. Changes in the occurrence and abundance of these and other organisms may indicate their association with different aquatic trophic conditions.
Phytoplankton of Selected Borrow Pit Ponds in Northern Illinois
(1980-05) Lipsey, Louis L., Jr.
Hydrobiological characteristics of 7 recent borrow pits resulting from highway construction were studied in 5 northern Illinois counties. Samples were taken from each pond at 10 different dates during the summer period. Half the samples were from the littoral zone and half from the limnetic zone. Measurements of pH, Biological Oxygen Demand, phosphorus, chloride, ammonia, nitrate and chlorophyll values were highly variable among the ponds. Fifty-nine species and varieties of phytoplankters, representing 38 genera and 5 divisions, were recorded. Relative abundance and general distribution of taxa varied considerably among borrow pits, as did the mean algal densities. Younger borrow pits had diversity indices lower than those of older ponds. Three species were present in all ponds. These were: Eudorina elegans, Navicula cryptocephala, and Nitzschia palea.
Influence of Mine Acid on Planktonic Rotifers
(1980-05) Horvath, Frank J.; Hummon, William D.
Planktonic rotifers were sampled in spring and summer from 2 lakes in southeastern Ohio. Unpolluted waters of Dow Lake were lower in sulfate and iron and higher in pH, hardness and alkalinity than acid mine polluted waters of Lake Hope. Rotifers of Dow Lake exceeded those of Lake Hope in species number, numerical abundance, species diversity, and faunal similarity among sample dates; similarity between lakes was negligible. Keratella cochlearis and Brachionus urceolaris, the most abundant rotifers in each of the respective lakes, both showed broad tolerances to pH. While B. urceolaris showed a large selective advantage at low pH, this was reduced and both species fared better at near-neutral pH. Neither species appeared sensitive to alternative pH conditions in preference tests.
Quaternary Stratigraphy and Depositional History of Glacial Lake Willard, Huron County, Ohio
(1980-05) Szabo, John P.; Hodges, David Alvin
Several borings and trenches across the Lake Willard Basin, Huron County, Ohio showed the presence of at least 2 tills and 2 glaciofluvial sequences. The youngest glaciofluvial sequence was overlain by marl and lacustrine silts correlated to classical Lake Willard, which in turn were overlain by organic soils, muck and peat. Wood from the upper part of the marl indicated that the lake possibly began to evaporate or drain as early as 12,500 Y.B.P. (years before present). Silts containing fragments of herbaceous vegetation and finally peat containing a stump and log of Thuja occidentalis (northern white cedar) indicated a swamp at 9,810 Y.B.P. Geomorphology and stratigraphy showed that the lake was probably not very deep during all or most of its existence. Fossiliferous marls suggested a very low energy environment after complete retreat of ice from the Willard area.
