Swamp Stompers, a Field Course in Secondary School
(1965-11) Linn, George F., Jr.
Swamp Stomping is an interdisciplinary (biology, geology and ecology) field course for high school students. The emphasis on field work is two-pronged—for future natural scientists to begin procedures inherent in field work and, secondly, to develop in all Swamp Stompers an appreciation of and concern for their natural resources so that as an electorate they will be better informed on the wise utilization of Ohio's natural resources.
The Transpiration Stream and Upward Translocation of Mineral Ions
(1965-11) O'Leary, James W.
Ca46 and P32 were supplied simultaneously to young Phaseolus vulgaris L. seedlings grown in solution. After short periods of uptake, the Ca45/P32 ratios in opposite leaves and opposite leaflets were very similar. This relationship also held when Ca45 and Cs137 were paired. Ca45/P32 ratios in lateral halves of the same leaf were in good agreement, also. However, the basal halves of leaves always had higher Ca4B/P32 ratios than terminal halves. There was a negative acropetal gradient of Ca45/P32 ratio in the stem, but the ratio in the trifoliate leaves was higher than in the primary leaves. When roots were removed prior to supplying the radioisotopes, the Ca45/P32 ratios in the foliage and stems were lower than in plants with roots intact. The data obtained support the en masse flow concept of ion movement through the stem.
Multiple Tills Near Shenandoah, Richland County, Ohio
(1965-11) Totten, Stanley M.
Near Shenandoah, in Richland County, is a geologic section that exposes ten different till units with some intercalated sand and gravel, and some evidence of weathering. The three uppermost tills correlate with the Hayesville, Navarre, and Millbrook Tills of the Killbuck Lobe, which are of Wisconsin age. The remaining seven till units occur below the oldest-named till in the Killbuck Lobe, the Millbrook Till, and are different from any other tills in the area. No definite age is inferred for any of these lower units. However, a 43^2-ft noncalcareous weathered sand between two of the lower tills may represent a major retreat of the ice, possibly the Sangamon Interglacial stage.

Ecological Processes at a Section of Shoreline of South Bass Island, Lake Erie
(1965-11) Langlois, Thomas H.
The tombolo at the northeastern end of South Bass Island, and a contiguous till bank on the southeastern shore were studied between 1936 and 1963. The bar of the tombolo represents the line of convergence of waves from the east which had passed on both sides of the dolomitic outcrop at the outer end of the bar. Waves from the west, approaching the bar at right angles, brought to it materials from both sides. Changing levels of Lake Erie alternately submerged and exposed the bar for prolonged periods. During periods of exposure, many plants appeared, which were subjected to overriding sheet-ice and then were eliminated by subsequent prolonged submergence. The adjacent till bank receded by a combination of the effects of shoving ice, frost, rain, waves, and winds (dehydration and sand-blasting). Boulders which washed out of the till bank were moved by waves and ice and accumulated near the landward end of the bar. These changes are illustrated by a set of dated photographs.
The Waves of Lake Erie at South Bass Island
(1965-11) Langlois, Thomas H.
South Bass is an island with a two-lobed outline near the southwest end of Lake Erie. It is composed of eastward-dipping dolomite rock. Wave erosion has produced high cliffs, characterized by spurs alternating with coves, which often have small pebble beaches, on the west shore, while low rock ridges separated by banks and beaches occur on the east. Locally on the west, large fallen blocks of dolomite partly protect the cliffs from the waves. On the east shore, flotsam is one of the major factors affecting the nature of the shoreline. Waves are locally dampened by masses of tape grass and, in winter, by water heavy with snow-curds and slush-balls. Cusps and cones of ice and splash-ice structures are also formed on shoals by winter waves.

The Winter Fishery of South Bass Island with a Census of the 1963 Catch
(1965-11) Keller, Myrl
The winter hook and line fishery of the South Bass Island Area in western Lake Erie has contributed phenomenal catches to the angler over the years. This fishery which operates on a sport and commercial basis has had a history of continual changes in species composition of the catch. Early records indicate that herring, Coregonus artedii (Le Seuer), saugers, Stizostedion canadense (Smith), burbot, Lota lota (Linnaeus), and walleye, Stizostedion vitreum vitreum (Mitchill), dominated the catches. During the more recent years yellow perch, Perca flavescens (Mitchill), and American smelt, Osmerus mordax (Mitchill), have dominated the catches. A creel census of the catch was made during the winter of 1963 to compare the past and present fishery. Estimates of the 1963 catch when compared to previous years were high. The total catch in 1963 was estimated to be 90,280 pounds or 285,280 fish. Of this total, 97.3 per cent were yellow perch. American smelt, white bass, Roccus chrysops, and walleye each made up less than 1 per cent of the catch.
A Recent Occurrence of Thermal Stratification and Low Dissolved Oxygen in Western Lake Erie
(1965-11) Carr, John F.; Applegate, Vernon C.; Keller, Myrl
Instances of thermal stratification have been detected only occasionally in western Lake Erie during the past 40 years, but when it does occur it is of considerable importance because of associated dissolved oxygen (DO) depletion in the hypolimnion. Data collected in June of 1963 give an indication of the meteorological conditions necessary to produce this thermal stratification. These conditions are: daily wind speed of less than 3.1 m/sec (7 mph); highest wind speed of less than 6.7 m/sec (15 mph); and an average daily temperature of more than 18.5 C for approximately 5 consecutive days. Weather records for Sandusky, Ohio, show these conditions to have occurred on 33 separate occasions between 1953 and 1963. These data suggest stable thermal stratification occurs more frequently than heretofore suspected. The 1963 data also show that in only 5 days of stratification DO in the hypolimnion was reduced to less than 3 ppm, whereas 28 days were required in 1953. This increased rate of DO depletion is probably due to an increase in the oxygen demand of the bottom sediments in recent years.

The Distribution of Fresh-Water Triclad Planarians in Jefferson County, Ohio
(1965-11) Stokely, Paul S.; Brown, Thomas S.; Kuchan, Frank; Slaga, Thomas J.
Seasonal distributions are described for fresh-water triclad planarians throughout the main drainage systems of most of Jefferson County, Ohio. The species found were Phagocata gracilis gradlis (Haldeman), Phagocata morgani (Stevens and Boring), and Dugesia tigrina (Girard). Dugesia dorotocephala (Woodworth), apparently a common species in the United States, was not found. Of the species found, P. g. gracilis was the most abundant, while D. tigrina occurred less abundantly. P. morgani was found rarely and only in association with P. g. gracilis. D. tigrina occurred characteristically in lakes and ponds of appreciable temperature ranges. P. g. gracilis occurred in cool, fresh springs. Planarians were not found in the large, swift, main streams and were absent from polluted water.
