Taxonomic Note On Fossil Glyptostrobus In Northeastern Arkansas, Eugene B. Whittlake

Journal of the Arkansas Academy of Science

Two papers by Brown (1936, 1962) are reviewed and discussed in relation to the validity of specific names applied to the fossil Glyptostrobus as found in North American deposits. Evidence is presented supporting the contention that G. nordenskioldi Brown n. comb, is the valid name for Glyptostrobus specimens from the Hooker site of northeastern Arkansas.

Fracture Pattern Analysis Employing Remote Sensing Techniques For Groundwater Movement With Environmental Applications: Preliminary Report, Bradford C. Hanson

Journal of the Arkansas Academy of Science

The study will consist of determining the relationship between fracture patterns and porosity-permeability changes in carbonate rocks with emphasis on groundwater movement. These porosity-permeability changes will be measured by relative groundwater movement, in the form of either springs, artesian wells, municipal supplies, or private wells. Relationships will be determined by plotting the positions of the measuring sites and correlating these sites with mapped fractures. Water yield is expected to be markedly greater for sites along fracture traces than for those located at random.

Stratigraphy And Sedimentary Structures Of A Middle Bloyd Fluvial Sandstone, Washington And Madison Counties, Arkansas, John M. Glenn

Journal of the Arkansas Academy of Science

A prominent quartz-pebble-bearing sandstone unit crops out at stream level along the East Fork of the White River in Madison County. Detailed geologic mapping indicates that the unit is stratigraphically positioned between the Brentwood and Dye Shale Members of the Bloyd Formation and is not the Greenland Member of the Winslow Fromation as previously supposed. Sedimentary textures and structures of the unit indicate that it was deposited by competent, unidirectional currents flowing in a southerly direction. These currents were related to a broad braided stream system.

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.

Etude Comparée Du Comportement Alimentaire De Deux Poissons Cavernicoles (Anoptichthys Jordani Hubbs Et Innes Et Caecobarbus Geertsi Blgr.), Georges Thinès, Nicole Wissocq

International Journal of Speleology

Systematic experiments on the cave-fishes Anoptichthys jordani and Caecobarbus geertsi show that the vertical orientation of swimming behaviour can be significantly modified by feeding the fishes during a period of 8 days before the experiments, either with food dropping to the bottom (Tubifex) or with food floating on the surface of the water (dried Daphnia). The observations have been quantified by recording systematically the position of the fishes in height in an aquarium divided in 3 levels of observation. The position of the fishes was recorded every 10 seconds during a total period of 15 minutes, divided in 3 periods …

Biométrie Spatiale Dans L'Écosystème Souterrain: Répartition De Meta Menardi Latr. (Argiopidae), R. R. Tercafs

International Journal of Speleology

The spatial distribution of 113 individuals from the species Meta menardi Latr. (Argiopidae) divided in 10 different populations living in 8 Belgian caves has been studied. A grouping test and the calculation of R according to Clark et Evans (1954), based on the measurement of the distance to the nearest neighbour, have been used. Results show that the individuals are distributed at random inside their biotope.

Interbasin Water Transfers And Groundwater Regulation In Nebraska, D. D. Axthelm, V. H. Dreeszen, C. A. Lewis

Conservation and Survey Division: Faculty and Staff Publications

On November 29, 1971, the Hamilton County Ground Water Con·­servation District sponsored a meeting on groundwater management and regulation. The meeting was held at Aurora, Nebraska, and was designed for irrigators from groundwater conservation dis­tricts and county irrigation associations. Various men from state and federal agencies spoke about a variety of problems that a.re related to groundwater management. Two of the talks that were presented at the meeting are reproduced here, as is a discussion of the rules and regulations that relate to the use of groundwater in the state of Nebraska.

A Geochemical Reconnaissance Of Puerto Rican Beach Sands, Louis Meinecke Iii

Masters Theses

"Twenty-four beach sand samples from the island of Puerto Rico were collected in 1964 by Dr. Ernst Bolter as part of a radiometric survey conducted by him. These samples were given to the author in 1969 for chemical analysis.

The purpose of this investigation was to conduct a geochemical reconnaissance study of the beach sands in order to determine the geochemical background and possible anomalies. This information could aid in offshore mineral exploration and source area determination.

This thesis presents the results of a quantitative chemical analysis for copper, lead, zinc, iron, manganese, aluminum, sodium, potassium, calcium, magnesium, and strontium …

Les Surfaces Cuticulaires Des Gnathopodes De Deux Crustacés Amphipodes: Niphargus (Gammaridé Hypogé) Et Gammarus (Gammaridé Épigé), Evelyne Sellem

International Journal of Speleology

Niphargus virei and N. schellenbergi (hypogean Gammarids) as also Gammarus pulex pulex (epigean Gammarid) show on the Gn1 and Gn2 of both sexes ornamented areas which were studied with a scanning electron microscope. The ornamentations are built up of teeth. These are simple in Gammarus pulex pulex and present a sexual dimorphism on the meropodite. In N. schellenbergi and N. virei they are as often as not grouped by three. In Orchestia (Talitrid) the teeth have their bases fusioned which forms pectinate scales showing a sexual dimorphism. Outside these areas, the gnathopod cuticle of N. virei, N. schellenbergi and …

Temperature And Relative Humidity Responses Of Two Texas Cave-Adapted Millipedes, Cambala Speobia (Cambalida: Cambalidae) And Speodesmus Bicornourus (Polydesmida: Vanhoeffeniidae), Eddie Bull, Robert W. Mitchell

International Journal of Speleology

The temperature and relative humidity preferences and tolerances of two Texas species of cave-adapted millipedes, Cambala speobia (Chamberlin) and Speodesmus bicornourus Causey, were studied. Both species showed gross preferences when tested in gradient chambers for temperatures and relative humidities approximating those of their cave environments. But C. speobia, the less adapted species morphologically, was the more selective of the two species for such conditions. S. bicornourus was far less tolerant of elevated temperatures and reduced relative humidities than was C. speobia. Discussed is a possible reason why a terrestrial troglobite like S. bicornourus would combine intolerance with a …

Late Quaternary Eustatic Sea-Level Changes Along The Malibu Coast, Los Angeles County, California, Peter W. Birkeland

United States Geological Survey: Staff Publications

Late Quaternary relative sea-level changes along the Malibu coast can be deciphered by study of geomorphic features and marine and associated stream deposits. Evidence for such changes includes (a) stream downcutting in large valleys during low stands of sea level, (b) stream aggradation in the same valleys during high stands of sea level, and (c) marine shoreline angles whose altitudes coincide with the tops of valley-fill stream deposits. This evidence, and open-system uranium-series dates for shells from the Corral and Dume terrace deposits, provide a time scale for certain sea-level changes. Evidence from other …

Miocene Amphicyonids (Mammalia, Carnivora) From The Agate Spring Quarries, Sioux County, Nebraska, Robert M. Hunt Jr.

Department of Earth and Atmospheric Sciences: Faculty Publications

The Miocene late Arikareean land mammal "age" is largely defined by the faunal assemblage from the Agate Spring Quarries and other nearby localities in the Harrison Formation of Sioux County, Nebraska. Amphicyonid carnivores of the genera Cynelos Jourdan and Ysengrinia Ginsburg were previously known only from European Oligocene and Miocene deposits. These genera are now known from the Harrison Formation of Sioux and Box Butte counties, western Nebraska, and therefore the late Arikareean fauna now includes three amphicyonids: Cynelos sp., (?) Ysengrinia sp., Daphoenodon superbus Peterson. The stage of evolution of these carnivores suggests a correlation of the Agate Spring …

Une Nouvelle Espèce Africaine Du Genre Stenasellus (Crustacea Isopoda Asellota) Du Bassin Du Niger, J. A. Birstein

International Journal of Speleology

The representatives of the genus Stenasellus (sensu lato) in Africa have been previously known from Cote d’lvoire, bassin of the Congo and Somali. The new species of this genus was collected from the well in the town Sicascau (Mali). This species differs from all others in the structure of the carpopodites of pereopods II-IV which are enlarged and armed with multiple curved spines. This character shows a distinct sexual dimorphism. In all other features St. laticarpus sp.n. belongs to the group of St. gjorgjevici Rac. and shows the closest resemblance to St. africanus Monod. It is now preferable …
