A Diurnal Zooplankton Migration Study In Lake Mead, Robert D. Staker

Publications (WR)

The diurnal vertical movement of zooplankton was first recorded in freshwater lakes by Weismann (1877) in Lake Constance (Bodensee), although Cuvier was credited with observing the migration of Daphniae in 1817 (Gushing, 1955). The migration is best observed in deep oligotrophic lakes and migrations of 50 m per day are described (Worthington, 1931). In addition, two species of chaetognaths are reported to migrate 400 m a day in marine waters off of Lisbon (Waterman and Berry, 1967) while Birge (1895) found little evidence of the phenomenon at all in Lake Mendota, Wisconsin. Most zooplankton that migrate rise at night and …

Phytoplankton Distribution And Water Quality Indices For Lake Mead (Colorado River), Robert D. Staker, Robert W. Hoshaw, Lorne G. Everett

Publications (WR)

Phytoplankton samples were collected in Lake Mend 6 times from September 1910 to June 1971 for 8 stations at depths of 0. 3, 5, 10, 20, and 30 m. These samples were processed through a Millipore filter apparatus and 79 planktonic algae were identified. Algal divisions represented were Bacillariophyta, 42 species; Chlorophyta, 18 ; Cyanophyta, 9; Chrysophyta, 3; Cryptophyta, 3; Pyrrophyta, 2; and Euglenophyta, 2. Blue-green algae were dominant in late summer and fall; green algae, diatoms, and, cryptomonads in winter; and green algae in spring. The early summer flora was best represented by the Chlorophyta, Cryptophyta, and Chrysophyta. Palmer's …

Pesticide Effects In A Simulated Soil Ecosystem, Raymond J. Samp

Masters Theses

The screening of pesticides to determine which were most inhibitory to bacteria was accomplished by testing the effects of 10 pesticides on 9 different organisms using the disk assay method. Results showed that Gram positive bacteria were more sensitive to all pesticides tested than were the Gram negative bacteria. In addition, the hormone herbicides were found to be the most inhibitory to these bacteria and 2,4-D (2,4-dichlorophenoxyacetic acid), a hormone herbicide, was chosen for subsequent in vivo studies.

A soil perfusion apparatus was used to determine the effects of 2,4-D in a typical soil ecosystem. Bacterial plate counts and nutrient …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

Conodonts Of The Mecca Quarry Shale, Timothy Charles O'Neill

Masters Theses

Conodonts were found to be abundant in the Middle Pennsylvanian, Mecca Quarry Shale, Parke County, Indiana. Nine forms were identified in this black fissile shale from a locality along Montgomery Creek near the town of Mecca. These elements are: Hindeodella parva, Idiognathodus delacatus, Gondolella sp. a, Ozarkodina delacatula, Lonchodina clarki, Ligonodina typa, Lonchodus simplex, Metalonchodina bidentata, and Neoprioniodus conjunctus.

International Journal of Speleology

Recent borings in the Veleka River drainage area (South Eastern Bulgaria) have shown a phreatic fauna with a new representative of Hydracarian of the family Momoniidae which constitute the type of a new genus: Momonisia phreatica n. gen. n. sp. The description is here given by the author. The most closely related Momoniid appears to be Momonia karelica Sokolov from Russian Carelia.

Données Faunistiques Et Ecologiques Sur Les Stenasellidae (Crustacea Isopoda Asellota Des Eaux Souterraines), Guy Magniez

International Journal of Speleology

Some important morphological features, which are discussed here, point out that the Stenasellids (Crustacea Isopoda Asellota) must be considered as a true family (Stenasellidae), independent from the Asellidae. A definition and a renewed diagnosis of the Stenasellidae Dudich, 1924, are given. Their relationships must be pursued, especially in the marine Parastenetroidea and in the psammic Microcerberidae. Until 1938, the group was known only from subterranean waters of southern Europe. Now, several genera and many thermophile species from north-tropical underground waters have been discovered in Africa (5 gen., 12 sp.), Asia (1 gen., 2 sp.) …

Biology And Ecology Of The El Convento Cave-Spring System (Puerto Rico), G. Nicholas

International Journal of Speleology

The El Convento Cave-Spring System is located at the head of the Quebrada de Los Cedros, approximately 20 km. west of Ponce, southwestern Puerto Rico. Although situated in an arid environment, the gorge receives sufficient moisture from the cave-spring system to support an abundant flora, with Bucida buceras and Bursera simaruba as the dominant trees. The cave is frequently flooded and possesses a rich nutrient substrate in the form of bat guano. Numerous orthopterans (Aspiduchus cavernicola and Amphiacusta annulipes), decapoda (Macrobrachium carcinus and Epilobocera sinuatifrons), and chiroptera (Brachyphylla cavernarum and Artebius jamaicensis) are present. …

Studies On The Abdominal Musculature Of The Subterranean Mysid, Lepidomysis Longipes (Pillai And Mariamma), C. N. Nath

International Journal of Speleology

The musculature of the hypogean mysid, Lepidomysis longipes (Pillai and Mariamma) is remarkably modified. It shows the absence of many muscles and poor development of others in the abdominal region. This is correlated with the subterranean nature of the animal.

Un Nouvel Asellide Interstitiel D'Espagne Méridionale Bragasellus Boui N. Sp. (Crustacea Isopoda Asellota) Et Considérations Sur Les Genres Européens D'Asellides, Jean-Paul Henry, Guy Magniez

International Journal of Speleology

Description of a new, unpigmented and eyeless Asellid, belonging to the iberian genus Bragasellus Henry et Magniez, 1968. Bragasellus boui, n.sp., lives on the bottom of a river that is a tributary of Guadalquivir River (Southern Spain). Bragasellus, Proasellus, Stygasellus and Synasellus are four genuine phyletic lines of European Asellidae, all of them independent of each other, and the authors confirm their validity as true genera.

Un Diploure Japygidé Cavernicole Inėdit De Corse Dipljapyx Beroni N.Sp., J. Pages

International Journal of Speleology

Dipljapyx beroni n.sp. has been collected from two caves in Corsica. From its antennae with 31 articles, chaetotaxia of urites and subcoxal organs well-characterized, it appears to be an endemic Corsican species, situated between D. humberti Grassi found in the western Alps, and D. italicus Silv. peculiar to the Italian Peninsula. It is closely related to the first of those two species. There is no morphologic feature indicating it as a troglophilic species.

Subterranean Crustacea Decapoda Macrura Collected By Mr. L. Botosaneanu During The 1973 Cuban-Roumanian Biospeological Expedition To Cuba, L. B. Holthuis

International Journal of Speleology

During the 1973 Cuban Romanian Biospeleological Expedition to Cuba 5 species of cavernicolous Decapod Crustacea were collected: the Palaemonidae Troglocubanus gibarensis Chace, T. eigenmanni (Hay) and Macrobrachium faustinum lucifugum new subspecies. The second of these species now is reported for the first time from Isla de Pinos. The third form proved to be a new subspecies of Macrobrachium faustinum (De Saussure), a freshwater shrimp which is widely distributed in the West Indies. The new subspecies is not only known from Cuba, but also material from Jamaica, Curacao and Bonaire is reported. A new locality is reported for Barbouria cubensis (Von …

Size And Growth Of The Eyes Of The Troglobitic Salamander Typhiotriton Spelaeus, Joseph C. Besharse, Ronald A. Brandon

International Journal of Speleology

The eyes of larval T. spelaeus grow by negative allometry, but in allometric coefficients they are not greatly different from E. lucifuga. The major differences in eye size, both absolute and relative to body size, between T. spelaeus and E. lucifuga are established prior Io the larval growth period. The eyes of T. spelaeus cease to grow at metamorphosis and are reduced in size thereafter. In addition, there is increased individual variability and bilateral asymmetry of eye size in adult T. spelaeus compared to both adult E. lucifuga and larval T. spelaeus. This variability, expressed as relative dispersion …

Free Amino Acids In A Cave Beetle Darlingtonea Kentuckensis Valentine (Coleoptera: Carabidae), R. J. Sperka

International Journal of Speleology

Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine and valine) and seven unidentified ninhydrin-positive spots were found. Beta-Alanine, alpha-amino-butyric acid, arginine, aspartic acid, cystine, hydroxyproline and methionine were not detected. No difference was observed in the free amino acids with respect to sex of beetle, time after feeding and method of sample preparation.

A Phytochemical Investigation Of Liverwort Frullania Franciscana Howe, Timothy Ta-E Huang

Dissertations and Theses

Liverwort Frullania franciscana Howe was found high on the allergic test scale by J. Mitchell of the Medical School of the University of British Columbia and co-workers. Frullanolide was isolated from Frullania tamarisci by J.D. Connoly and by G. Oisson and his co-workers.

The plant sample, collected in Oregon, was hand separated, confirmed, air dried and milled before the extractions were done. A Soxhlet extraction with ether and cold extractions with n-hexane and with ether were carried out. Ether is a better extraction solvent than n-hexane for cold extraction.

Column chromatography was used for the separation of the extract based …

A Field Study Of Infiltration On Various Agricultural Soils, Stephen J. Stephen

Theses and Dissertations (Comprehensive)

The purpose of the study was to ascertain if infiltration and temperature varied significantly among the selected soil types of the Smithfield, Otonabee, Wendigo and Farmington Series. These data were gathered from field tests performed during the summer months in Ontario and Victoria Counties.

A stopwatch was used to measure the number of seconds that were required for 0.8 inches of water to disappear into the soil inside a 4 inch diameter single ring infiltrometer which had been placed one inch into the soil surface. The soil temperature was recorded at the same time.

The sites were chosen by stratified …

Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack

Faculty Publications

Partial cross sections (opacity functions) for rotational transitions in atom-diatom collisions are computed in the infinite-order sudden (IOS) approximation and compared with accurate close-coupling (CC) calculations. Agreement is good in the dominant coupling (small total angular momentum J) region. Simple methods for calculating integral inelastic cross sections are discussed, and it is found that accurate cross sections can often be computed very simply, even when large numbers of channels are coupled together, by using IOS or first-order sudden (FOS) approximations for small J and CC or exponential Born (EBDW) methods for large J.

A Study Of Water-Soluble Inhibitory Compounds (Algicides) Produced By Fresh-Water Algae, Denny O. Harris, Manhar C. Parekh

KWRRI Research Reports

A complex system of growth inhibitors was observed in the green algae (Volvocaceae). Inhibitors were found in the culture filtrates of some genera which limit their own growth (autoinhibitors) while others in the family produce substances which check the growth of other genera (heteroinhibitors). These inhibitors were destroyed by autoclaving. It was decided that Pandorina morum, which produced the strongest inhibitor and Volvox tertius, the most sensitive to the inhibitor would make an excellent model system for a study of the chemical and physical properties of these naturally occurring algicides. The algicide could be removed from actively growing cultures about …

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Fao Quelea Research In Africa, Jeffrey J. Jackson

Bird Control Seminars Proceedings

Large scale grain growing schemes are developing rapidly in Africa and the importance of birds as pests becomes more evident each year. Although the potential production of cereals is quite high in some parts of Africa, effective methods for protecting the new schemes from bird damage will have to be developed if their food raising potential is to be realized. The best known of the avian pests of cereals in Africa is Quelea quelea. In addition to their importance as pests their notoriety is due to their intensely gregarious nature. The cloudlike feeding swarms and dense nesting colonies with millions …

Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell

Bird Control Seminars Proceedings

On December 5, 1965 the Governor of Wisconsin signed into law a statute permitting claims against the State for damages to crops by wild geese and ducks. This law had been rushed through the legislature in the wake of a rash of crop depredation complaints caused by Canada Geese in their off-refuge feeding flights from the Horicon National Wildlife Refuge. This paper reviews our experiences with waterfowl depredations in the development of a cooperative program by State and Federal wildlife agencies that has held a potentially serious wildlife problem to a minimum of financial losses and public relations concern.
