Range Extension and Notes on the Shrew Sorex Cinereus in Ohio
(1965-01) Gottschang, Jack L.
In the course of trapping old fields on 3, 4, and 5 December 1962, fifteen Sorex cinereus were caught in Butler Township, Mercer County, 1.6 miles north of the town of Coldwater, Ohio. This is an extension 85 miles to the southwest of the range for the species in Ohio. Included are reproductive data, weights, and measurements, as well as a discussion of subspeciation.
A Mathematical Description of the Toxicity of "Sernyl" to Goldfish
(1965-01) Wilber, Charles G.
The toxicity of the drug 1- (1-phenylcyclohexyl) piperidine, "sernyl", to goldfish, Carassius auratus, was tested. Median tolerance limits, median lethal concentrations (LCt 50) and the relation of the quantity Ct to time were calculated. The relation of concentration of sernyl to time of exposure may be expressed by the equation: Ct = 34+ 23t0-43. The results indicate that at higher concentrations of sernyl the LCt 50 is less than at lower concentrations. The value of K = 34 in the above equation provides a new constant for the tolerance of goldfish to serynl.
A List of Fireflies Known of Likely to Occur in Ohio, with Special Notes on Species of Ellychnia (Lampyridae: Coleoptera)
(1965-01) Marvin, Daniel E., Jr.
This paper provides a check list of Ohio Lampyridae. The species are listed in phylogenetic order and distribution records are given by counties. This study reveals 8 genera and 24 species recorded from Ohio. Pyropyga minuta LeConte is a new state distribution record. Examination of male genitalia of specimens of the genus Ellychnia LeConte clearly shows that E. corrusca (Linnaeus), E. autumnalis (Melsheimer), and E. lacustris LeConte should each be classified as a distinct species.
Early Forest of Delaware County, Ohio
(1965-01) Ogden, J. Gordon, III
Data from two land surveys were utilized to reconstruct the original forest composition of a county in central Ohio. The 1832 survey divided the county into 12 townships consisting of 5 sections approximately 2.5 miles on a side. Corners were determined by recording the name, bearing, diameter, and distance from a survey point or corner, of pairs of trees. The dominant (per cent basal area) trees were beech (35.7 per cent), white oak (16.0 per cent), sugar maple (15.7 per cent), and red oak (14.0 per cent). Other components of the forest vegetation (in decreasing order of basal area) were white ash, hickory, black oak, American elm, basswood, soft maple, blue ash, black ash, red elm, and buckeye. A second survey, completed in 1835, subdivided the sections into smaller parcels with trees recorded at 200- to 500-ft intervals. Four of these sections are described from the eastern, central, and western parts of the county. In addition to the species listed in the 1832 survey, 10 additional species were recorded. Weed trees such as black locust and honey locust were not mentioned in either survey. Analysis of pair distances and stem diameters indicates that the forests of 1832 and 1835 were probably straight-stemmed and tall. It is not probable that these forests were second growth, although it is quite likely that some selective cutting had taken place.
Freshwater Algae of the Central Death Valley Desert
(1965-01) Brown, Carole Morgan
The Central Death Valley desert was investigated at seasonal intervals between 1959 and 1961 to determine the algae indigenous to its freshwater ponds and streams. Myxophyceae, Chlorophyceae, and Bacillariophyceae were represented by substantial populations throughout the year. Blue-green algae were especially predominant under the thermophilic conditions. Thirty-two previously unrecorded species were also found in the survey.
A Radiocarbon Dated Pollen Sequence from the Wells Mastodon Site Near Rochester, Indiana
(1965-01) Gooding, Ansel M.; Ogden, J. Gordon, III
A radiocarbon date (1-586, 12,000=fc450) has been obtained from wood beneath a mastodon (Mastodon americanus) in north-central Indiana. The sediment sequence includes 72 inches of marl at the base, overlain by 12 inches of sand, capped by 34 inches of peat. The peat is truncated at the top by fire and cultivation. Pollen spectra from the marl associated with the mastodon burial indicate a predominantly coniferous forest consisting of spruce (Picea), fir (Abies), birch (Betula), and ash (Fraxinus) with small amounts of oak (Quercus), Hickory (Carya), and elm (Ulmus) pollen. Field evidence and pollen data indicate that the animal died prior to the formation of the peat. Correlation of this sequence with other radiocarbon-dated pollen sequences indicates that the mastodon died prior to the replacement of spruce pollen by oak pollen approximately 10,500 years ago. Molluscan data support the inferences derived from the pollen analysis.
