Spatial and Energy Requirements of Beavers
(1967-07) Brenner, Fred J.
The relationship between energy intake and metabolic requirements of beavers {Castor canadensis) is discussed in regard to the spatial requirements of three colonies. A 26-pound yearling beaver requires 850 kcal of digestible energy, or 1.5 lb of fresh aspen per day, to maintain its daily metabolic processes with no additional growth. In order for such a beaver to attain maximum growth, 2040 kcal or 3.6 lb of fresh aspen/day are required. An acre of aspen produces 5,840 lb of food, so there: would be sufficient energy to maintain a population of 10 beavers for 442 days if no growth of beavers occured. If one acre of aspen would maintain the population for one year, there would be 2.8 lb of fresh aspen/day which could be utilized for growth within the population.
A Study of Two Plumage Aberrations in the Male Redwinged Blackbird (Agelaius Phoeniceus)
(1967-07) Schodorf, Robert
Two different traits of albinism were studied in samples of male Redwinged Blackbirds. Eighty-eight per cent of 627 male Redwings sampled possessed a white spot at the base of the rectrices, the size of this white area being smaller in the immature redwing males than in the adults. Samples of immature males after they had obtained first basic plumage revealed a white spot size distribution essentially the same as that found in the adult sample. Breast banding, the other trait studied, was found to occur in 5.2 per cent of the adult males sampled.
The Adsorption of a Cationic Surfactant on TiO2 from Aqueous Solutions
(1967-07) Corsaro, Gerald
urface-tension measurements by the DuNuoy tensiometer technique have been used to estimate the number and size of rubber latex particles in aqueous suspension. The present report demonstrates the applicability of the bubble-pressure method to measuring the surface tension variation of solid aqueous suspensions on additions of a cationic surfactant. A consistent relationship between the specific surface area of the. titania samples and surfactant adsorption is shown
The Occurrence of the Coral Genera Pseudozaphrentoides and Lophamplexus in the Pennsylvanian of Ohio
(1967-07) Colson, Calvin T.
Only two genera of solitary corals, Lophophyllidium and Stereostylus, were known previously from the Pennsylvanian in Ohio. Recent studies of solitary corals from Pennsylvanian strata in Ohio have recorded two genera, Pseudozaphrentoides and Lophamplexus, from the Vanport Limestone of the Allegheny division of the Pennsylvanian. This study enlarges the known Pennsylvanian coral genera and the geologic range of Ohio Pennsylvanian corals.
Remarkable Sympatry in the Winter Stoneflies Allocapnia Indianae and A. Ohioensis, a Pair of Sister Species
(1967-07) Ross, Herbert H.; Freytag, Paul H.
Two extremely closely related species of stone flies, Allocapnia indianae Ricker and A. ohioensis Ross and Ricker, have almost perfectly sympatric ranges extending from southcentral Kentucky to southeastern Ohio, with isolated areas of distribution in south-central Indiana and in New York. Both species appear to be restricted to small streams having cave or spring origins. A comparison of their distribution with features of Wisconsin glaciation suggests that (1) the Wisconsin glacial lobes separated the area of occurrence of the ancestral species of these two living stone flies into two isolated geographic units, (2) these isolates evolved into distinctive species, and (3) since then the two resulting species have achieved rigid genetic isolation and dispersed throughout each others' range. It is suggested that the original isolation of the pre-indianae and pre-ohioensis populations occurred just prior to the Wisconsin glaciation.
Effect of Light and Carbon Dioxide on the Loss of Manganese from Chlorella Cells
(1967-07) Eyster, H. Clyde; Woodruff, Marjorie Nix
Using radioactive manganese-54, it was shown that appreciably more manganese was lost from Chlorella cells in the light than in the dark under conditions which did not permit aeration nor the addition of carbon dioxide. Exposure of Chlorella cells to (1) pure nitrogen, (2) 5% CO2 in nitrogen, (3) air without CO2, and (4) 5% CO2 in air indicated that the loss of manganese was due mainly to the absence of CO2 and not to a deficiency of oxygen.

Two New Species of Water Mites from Ohio
(1967-07) Cook, David R.
Two new species of Hydracarina, Tiphys weaveri (Acarina: Pionidae) and Axonopsis ohioensis (Acarina: Axonopsidae), are described from Wayne County, Ohio. The former species inhabits temporary ponds; the latter was collected in a newly formed lake.

The First Appearance in Ohio of the Theory of Continental Glaciation
(1967-07) White, George W.
Louis Agassiz published his "glacial theory" in Etudes sur les glaciers in October, 1840. Edward Hitchcock wrote approvingly of the theory in 1841 and reproduced some of the Agassiz plates. Professor Samuel St. John of Western Reserve College reproduced one of the Hitchcock glacier plates and wrote favorably of the theory and described glacial drift in general in the first geology textbook published in Ohio, in 1851 at Hudson. St. John's influence was particularly important in the career of his student, John Strong Newberry, the famous geologist. Newberry's interest in glacial deposits, and especially in the origin of kames, may be traced to St. John, his geology teacher.
Seasonal and Daily Chirping Cycles in the Northern Spring and Fall Field Crickets, Gryllus Veletis and G. Pennsylvanicus
(1967-07) Alexander, Richard D.; Meral, Gerald H.
In southeastern Michigan, Gryllus veletis chirps from mid-May until early August, barely or not at all overlapping with its sympatric sibling, G. pennsylvanicus, which chirps from early August until mid-November. When nights are warm, both species chirp chiefly at night; when nights are cold, they chirp solely by day.
