Utilization of Woody Plants by Beavers in Northeastern Ohio
(1970-03) Henry, Dale B.; Bookhout, Theodore A.
Relative abundance of woody plants and their utilization by beavers (Castor canadensis) were measured on watersheds in Ashtabula and Columbiana Counties, Ohio, in 1966-67. A food index showed aspen (Populus sp.), alder (Alnus sp.), hop-hornbeam (Ostrya virginiana), black cherry (Prunus serotina), willow (Salix sp.), dogwood (Cornus sp.) and oak (Quercus sp.) to be major foods; 20 different woody species were utilized. The amount of use of a single species seemed to depend largely on the relative availability of all food species. All topographic features may influence site occupancy by beavers, but in this study, fluctuating water level was the factor most detrimental to sustained habitation.

Color Preferences of the Xanthid Mud Crab Rhithropanopeus Harrisii
(1970-03) Gerberg, Gary; Schwartz, Frank J.
Male and female xanthid mud crabs, Rhithropanopeus harrisii, when subjected both to paired and to simultaneous-combination color tests, exhibited nearly identical preference patterns for black, yellow, green, red, blue, and ultraviolet colors (listed in order of choice), although some individual variation occurred. Further investigations into the statistically significant reactions to blue and ultraviolet colors by both sexes is warranted.
An Alaskan Leafhopper that Lives Normally Beneath Icy Tidal Submergence
(1970-03) DeLong, Dwight M.
A leafhopper of the Macrosteles fascifrons (Stal) complex lives on an alkali grass, Puccinellia nutkaensis (Presl) Fern. & Weath., on the tidal flats of Muir Inlet in Glacier Bay, Alaska. The tidal water, with icebergs and a temperature of approximately 1° C, covers the grass twice daily and the leafhoppers in all stages—egg, nymph, and adult—survive beneath the water for extended periods of time. The winged adults do not attempt to leave the plants when the tidal water begins to submerge them and none were obtained from vegetation surrounding the tidal fiats either before or after submergence.
Rate of Collapse of Snow-Bank Kames in Adams Inlet, Southeastern Alaska
(1970-03) McKenzie, Garry D.
Mounds formed by the differential ablation of snow covered by varied thicknesses of sand that has slumped onto a snow bank from an adjacent bluff are here named snow-bank kames. The rate of collapse of these mounds, calculated from temperature observations in the sand and using the temperature-gradient method, was 2.2 cm day-1. The observed rate of lowering for these mounds was between 2.6 and 3.2 cm day-1. The difference in rates may be due to mechanisms of heat transfer other than conduction.

A Study of the Decarboxylation of Trichloroacetic Acid in Solutions of Water and Dimethylsulfoxide
(1970-03) Laque, William E.; Ronneberg, Conrad E.
The decarboxylation of trichloroacetic acid has been found to occur readily at temperatures as low as 25.0°C in the presence of dimethylsulfoxide in water solutions, a fact not previously reported in chemical literature. The reaction rate is dependent upon the concentration of the dimethylsulfoxide. The reaction rate constant increases about sixty percent as the concentration of dimethylsulfoxide (DMSO) is increased from c. 50 percent to c. 86 percent. The reaction is first order and the rate is also influenced by the actual concentration of the trichloroacetate ion. An effect of the DMSO is to increase the concentration of this ion. The paper presents density curves at 20.00°C and 25.00°C (each±0.05 °C) for solutions of DMSO in water.
Strand Lines and Chronology of the Glacial Great Lakes in Northwestern New York
(1970-03) Calkin, Parker E.
Recent restudy of Glacial Great Lake history in northwestern New York tends to confirm a general sequence of nine to ten major lake stands, predicted from others' work in adjacent areas in the Erie and Huron basins. However, some doubt is raised as to the dating and position of the ice margin at the initiation of this sequence. The evidence suggests that glacial lake waters rose to form Lake Whittlesey between 12,700 and 13,800 years B.P., with advance to either the Lake Escarpment, Gowanda, or Hamburg End Moraines. Lake Whittlesey lowered to the Warren I level about 12,700 B.P., after the ice margin had retreated less than one mile from the main portion of the Hamburg Moraine. A second but brief lake stand (Warren II) is weakly suggested by a lower set of beach ridges. However, such a stand must have been very brief, for it gave way to a much lower lake soon after the ice margin had retreated from the next more northerly (Alden) moraine. This much lower lake stage, probably correlating with Lake Wayne, occurred during construction of the gravelly Buffalo Moraine and before waters rose again to form Lake Warren III. Lake Warren III, evidenced by the strongest beaches in this area, ended following ice-margin retreat from the Batavia Moraine, when lake level dropped 40 feet to the Lake Grassmere level. Evidence for lower and later glacial lake stands is sparce, but includes features which may correlate with the short-lived Lakes Lundy and Early Algonquin, and a much smaller local glacial lake, Dana. Lake Dana, the last glacial lake in this portion of the Erie basin, was extinguished as the terminus of the ice sheet retreated north of the Niagara escarpment and into the present area of Lake Ontario and thus opened the Rome outlet to the Mohawk-Hudson River drainage system. The average of several C14 dates from the Lake Ontario basin suggests that this event occured prior to 12,100 years ago. At least 170 feet of isostatic uplift has taken place on the Buffalo isobase since Lake Whittlesey time.
An Annotated List of the Fishes of Lake Erie and its Tributary Waters Exclusive of the Detroit River
(1970-03) Van Meter, Harry D.; Trautman, Milton B.
Dramatic fluctuations have occurred in the abundance of many species in Lake Erie and its tributary waters in the last century. Some fishes of former economic importance have become commercially extinct. Several species apparently have been extirpated, especially in the tributaries. It is believed that further changes in the abundance of other species will occur in the near future. This publication consolidates the confirmed records of fish species for Lake Erie and its tributaries. One hundred and thirty-eight species of fishes are listed and, where appropriate, brief comments on present and past distribution, and abundance and economic status are given. Selected references are listed as additional sources of information for each species.
