Transplantation of the Upper Reproductive Tract to the Spleen in the Female Rat : A Method for Studying the Pituitary-Gonadal Relationship
(1968-01) Leavitt, Wendell W.
surgical procedure was developed for autoplastic grafting of the ovary into the splenic circulation. The ovarian transplant is joined to the spleen by an attached piece of oviduct and uterus. Direct arterial connections to the graft are maintained throughout the procedure; there is no direct contact of splenic and ovarian tissue. Transplantation of the left utero-tubo-ovarian segment and removal of the contralateral ovary was performed best in immature rats. The ovarian artery and vein were removed from the graft one week later. The transplanted ovary hypertrophied while the uterus in situ remained atrophic. The relationship between the weight of the splenic ovary and the uterus in situ was useful in evaluating ovarian-graft response to the increased gonadotropin secretion which occurs. Gonadotropin secretion in this situation is discussed in light of possible progestogen feedback to the hypothalamo-hypophyseal system
Colton Formation (Eocene: Fluviatile) and Associated Lacustrine Beds, Gunnison Plateau, Central Utah
(1968-01) Marcantel, Emily L.; Weiss, Malcolm P.
The Colton Formation consists mostly of fluvial (floodplain and channel) deposits that are less resistant and more highly colored than the adjacent lacustrine beds of the Flagstaff and Green River Formations. The contrast between the fluviatile and lacustrine strata is indicated by several lithic and faunal characteristics that occur in a short stratigraphic interval, and that permit precise and regionally persistent recognition of the limits of the Colton Formation. The Colton is distinguished by: 1) red, yellow, or brown, fine- to medium-grained, micaceous, feldspathic subangular sandstones that are crossbedded, thick-bedded, laterally non-persistent, and typically lens-shaped in cross-section; 2) red, green, or purple, somewhat silty or sandy mudrocks and shales that are poorly fossiliferous and poorly bedded; 3) limestone beds, locally of pastel colors, that are generally less than 1 foot thick, non-persistent, tough, platy and poorly fossiliferous; 4) far fewer fossil snails and clams than the regionally continuous carbonate units of the middle and upper Flagstaff Formation. In contrast, lacustrine beds that bound the Colton Formation are characterized by the following features; 1) pale grey, fine-grained, subrounded sandstones, without crossbedding, that are rather thin and widespread (Flagstaff only); 2) yellow-brown or gray, thin-bedded, tough and platy limy shales that are fossiliferous and interbedded with limestone and dolomite units; 3) limestones and dolomites of several petrographic types that are two feet thick or more, and laterally persistent. When distinguished by the sum of these characteristics, the Colton consists in the central Gunnison Plateau of a northward-thinning wedge. From a thickness of 800 feet at South Maple Canyon, it thins to less that 550 feet at Wales Canyon, north of which it has been removed by erosion. The formation becomes much more clastic toward the north in the area studied.
Distribution and Abundance of the Japanese Snail, Viviparus Japonicus, and Associated Macrobenthos in Sandusky Bay, Ohio
(1968-01) Wolfert, David R.; Hiltunen, Jarl K.
A survey of the macrobenthos of Sandusky Bay, Lake Erie, in June, 1963, provided information on the abundance and distribution of the introduced Japanese snail, Viviparus japonicus, which has become a nuisance to commercial seine fishermen. The abundance and distribution varied considerably within the bay; at the time of the survey, most snails were found near the north-central shore. Environmental characteristics were nearly uniform and had no apparent effect on the distribution; concentrations in different areas at different times appeared to result from water movements induced by winds. The time of the study coincided with a period of reproduction; young-of-the-year snails were most abundant in areas where adults were most common. The frequency distributions of shell height and diameter suggested the presence of two age groups of adults in the population. Considerable natural mortality was seen, both at the time of the study and in other seasons. Only three other gastropods were observed in the bay; the most abundant was another viviparid, Campeloma decisum. Other mollusks present were four species of Sphaeriidae and 18 species of Unionidae. A summary of invertebrates found, other than the mollusks, is also presented.
Some Parasites of the Common Crow, Corvus Brachyrhynchos Brehm, from Ohio
(1968-01) Jones, Joseph, Jr.
Thirty-one species of parasites were taken from 339 common crows over a twentymonth period in Ohio. Of these, nine are new host records: the cestodes Orthoskrjabinia rostellata and Hymenolepis serpentulus; the nematodes Physocephalus sexalatus, Splendidofilaria quiscali, and Splendidofilaria flexivaginalis; and the arachnids Laminosioptes hymenopterus, Syringophilus bipectinatus, Analges corvinus, and Gabucinia delibata. Twelve parasites not previously reported from the crow in Ohio were also recognized. Two tables, one showing the incidence and intensity of parasitism in the common crow in Ohio, the other listing previous published and unpublished records of common crow parasites, are included.
The Effect of DDT on Reproduction in Mice
(1968-01) Cannon, Marvin S.; Holcomb, Larry C.
Adult laboratory mice {Mus musculus) were fed diets of chick starter mash containing 200 and 300 ppm of DDT. Some tolerated DDT feeding quite well; others died early in the experiment, shortly after feeding had begun. Some mice were able to survive for extended periods. The average number of young born to mice exposed to levels of 200 and 300 ppm of DDT was similar to that of the control animals. However, the number of female mice dying during the gestation period was much higher among the test animals. The number of young surviving from the test animals was much smaller as compared to that of the control litters. No changes in the gross histology of tissues in treated animals were noted. While both kidney and ovaries in test females decreased in weight, the adrenal glands increased in weight. The kidneys and testes of test males decreased in weight as the adrenal glands increased in weight, and they lost body weight appreciably before death. A two-sided t-test showed a significant difference between the mean weights of adrenals from control and from test male animals treated with 200 and 300 ppm of DDT. Conception was nearly identical in the control and treated groups. Better reproductive results were obtained in the control animals because many treated females died before giving birth. Starving DDT-fed mice led to almost immediate death, accompanied by symptoms of DDT intoxication. It is concluded that reproduction in mice can be affected by exposure to 200 and 300 ppm of DDT, resulting in death of females during the gestation period, death of male animals, and/or death of young. Further indiscriminate use of insecticides may increase reproductive failures among all wildlife, which could be of more importance than direct mortality.

A Laboratory Investigation of Maturation in the Cuban Burrowing Cockroach Byrsotria Fumigata (Guerin)
(1968-01) Fleischmann, W. R., Jr.; Miller, H. K.; Skavaril, Russell V.
The study was undertaken to provide information on the number of males and females, number of instars, and accumulative instar lengths in the Cuban burrowing cockroach. Forty-four broods of Byrsotria fumigata (Guerin) were reared from parturition to maturity under controlled laboratory conditions. Each cockroach was color-coded with a different color for each instar, and molts were recorded on the day that they occurred. Development time to the adult stage varied from five to eight months. Seven to nine instars were observed, with males having seven to eight, and females having eight to nine instars. There were no significant differences between the total numbers of male and female cockroaches at the adult stage. Descriptive statistics were computed for the data on accumulative length, in days, of each nymphal instar period.
Vegetation in Fallow Vineyards, South Bass Island, Ohio
(1968-01) McCormick, Jack
More than a third of the 1500-acre surface area of South Bass Island, Ottawa County, Ohio, is occupied by vineyards fallowed between 1900 and 1955. A floristic reconnaissance was made in July, 1962, to describe weed vegetation in an active vineyard, in four vineyards fallowed and unmowed from 7 to 24 years, and in areas mowed since retirement. The active vineyard had the most diverse flora, but annual and biennial species composed the bulk of the vegetation. Perennial forbs were predominant in undisturbed vineyards fallowed 7 to 16 years and in older areas mowed after fallowing. Forest development was found to be more rapid on the north section of the island, where a 24-year-fallow vineyard supported a closed-canopy box elder-white ash forest. Box elder (Acer negundo) was not found in fields on the south section and forest development there apparently leads to a sugar maple-hackberry type. Acquisition by a governmental or private agency of one or more fallow vineyards on each section of South Bass Island is recommended. Protection of such areas would preserve open space, provide areas for studies of later trends of vegetation development and assure availability of sites for terrestrial field studies by classes from the Stone Laboratory of The Ohio State University.
