Limnology Of Four Bauxite Open-Pit Lakes, George L. Harp, Ronald D. Hubbard

Journal of the Arkansas Academy of Science

The aquatic flora and fauna and 18 physicochemical characteristics of four bauxite open-pit lakes were studied from September 1969 to August 1970. The least acid lake (pH 3.4-4.4) supported 49 different aquatic insects, plankton, and higher aquatic plants. The most acid lake (pH 2.7-3.2) supported only 26 different plants and animals. Bauxite open-pit lakes within the pH range studied appear to be as relatively unproductive as their coal strip-mine lake counterparts, with which they share physicochemical and biological characteristics. Benthic macrofaunal diversity and abundance appear to be related more closely to distribution and abundance of leaf detritus than to hydrogen-ion …

Bulletins - 3000 - 3999

The systematic investigations of the potential of the Ord area for irrigated farming began during the Second World War when the possibilities of damming the river were first examined, initial soil survey was carried out, and agricultural experiments started. The Kimberley Research Station was established on its present site in 1945. A year later the State and Commonwealth Governments agreed to finance and operate the Station jointly, with CSIRO and the Western Australian Department of Agriculture being responsible for research.

The construction of the main dam designed to store 5,675 million m" ( 4.6 million acre feet) was completed in …

Septic Tank Nutrients In Groundwater Entering Lake Sallie, Minnesota, David Robert Lee

Theses and Dissertations

The nutrient contribution of septic tanks to a lake was evaluated at Lake Sallie, in glacial outwash terrain of northwestern Minnesota. Groundwater entering the lake was collected by covering 0.258 m2 of lake bed with a bottomless cylinder vented to deflated plastic bag. Inflow velocity ranged from 0.01 to 2.5 micrometers per-second along 30% of the lakeshore. Groundwater inflow along an 800 m segment of shore amounted to 4.50 x 105 m3/year, and was uniformly distributed along the shore, but decreased exponentially away from shore.

Effluent from a heavily-used lakeside septic tank fanned out along the surface of the water …

Untersuchungen Über Das Nervensystem Von Hexaurus Merkli J. Frivaldzsky (Coleoptera, Bathysciinae), Michail Kwartirnikov

International Journal of Speleology

The central nervous system of the beetle Hexaurus merkli J. Frivaldzsky corresponds to the formulae 2+2 / 0. The relative proportion of the corpora pedunculata reaches 5.5% and that of the olfactive lobes 6.8% of the total mass of the upper-exophagus ganglion. The under-exophagus ganglion corresponds to 29.5% of the total mass of the head-ganglion. It is furthermore demonstrated both in the upper- and under-exophagus ganglion that neurosecretory cells exist. Corpora allata and corpora cardiaca are also present.

On The Food And Feeding Habits Of Lepidomysis Longipes (Pillai & Mariamma) (Crustacea Mysidacea), C. N. Nath, N. K. Pillai

International Journal of Speleology

The amount of food available to the subterranean mysid, Lepidomysis longipes (Pillai & Mariamma, 1964) in its habitat has been calculated and analysed. Lepidomysis appears to feed mainly on decaying vegetable matter. Lepidomysis shows many modifications in its external morphology. Consequently, the mode of feeding has undergone some marked changes from that of its epigean relatives. L. longipes is a discontinuous feeder.

Optic Regression In A Subterranean Mysid (Crustacea, Mysidacea), C. N. Nath, D. M. Thampy, N. K. Pillai

International Journal of Speleology

The eyes of the blind subterranean mysid, Lepidomysis longipes are stalked and paired in the embryonic condition. They fuse together in the adult and the optic ganglia are enclosed in a single eyeplate. The ganglia are arranged in the form of an arc on either side anterodorsal to the brain inside the single eyeplate.

Les Japygidés Cavernicoles De La Faune Française, Jean Pagés

International Journal of Speleology

Twelve species of Japygids are cites from France. Six are known with certitude from caves. None of them shows any morphological modification which can be ascribed to cavernicolous life. All of them are found outside caves except Metaj. doderoi Silv. which is known from a unique female from Castel Mouly cave. To take into account the selection which seems to occur among the species, the term “subtroglophile” is proposed to include those which can be found in the caves.

Harpolithobius birsteini n.sp. is the second troglobiotic Lithobiid known from Soviet caves. The other species collected must be considered as mere troglophilous.

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 …

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.

Arctic Ecology: A Decade Of Experience, John F. Schindler

UMR Journal -- V. H. McNutt Colloquium Series

A quick glance at the title of this presentation and the reader braces himself for another antipollution or “save-the-sod” type of discourse that has become so popular these days. I do not wish to detract from the importance or the need for such efforts but I would like to address myself to the the broader meaning of the term.

Ecology--the word comes from the Greek root “oikos” which means house or household. What I’d like to do is to tell you about this “house” I’ve been living in for the past 10 years.

The Environmental Challenges Facing Taps, A. V. Cardin

UMR Journal -- V. H. McNutt Colloquium Series

Before the potential benefits of the recent oil discoveries on the North Slope of Alaska can be realized, the oil must be transported to refining and marketing areas. The Alyeska Pipeline Service Company has the responsibility for the first step in this transportation—to design and construct the Trans Alaska Pipeline System. We will pipe the oil from the discovery areas near Prudhoe Bay to an ice-free, deep-sea tanker loading terminal at Valdez of the South Coast of Alaska. From Valdez the oil will be transported to the West Coast by tankers. This is the most feasible system of a number …

Role Of Transition Metals In Nitrite Decomposition In Soil, J. S. Bajwa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron and copper increased the decomposition of nitrite significantly during the first two hours of reaction when 150 parts per million (ppm) of nitrite and nitrogen was added to an acidic soil. Manganese was found to have a slight effect. There was no additional effect of the added metals after two hours reaction time.

The higher concentration of metals was not effective in catalyzing the decomposition of the added nitrite in nitrogen. All the added nitrite nitrogen was not recovered and the deficit could be due to the formation of nitrogen gas.

Effect Of Time And Rate Of Application Of Nitrogen On The Yield Of The Mexican Wheat Under The Semi-Arid Conditions Of Tunisia, Habib M. Halila

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of the time and rate of application of nitrogen on the yield of high yielding varieties of wheat was studied under the semiarid conditions of Northern Tunisia.

Analysis of the experimental data showed that nitrogen increased the yield of wheat in most locations which were chosen for this experiment.

In high rainfall areas, late application of nitrogen (tillering, jointing stages) was more effective than early applications. The optimum yield was obtained by applying 90 kilograms of nitrogen per hectare.

In the medium to low rainfall area, early applications (seeding time) were more effective than the late ones. The …

The Effect Of Alternate Wetting And Drying On The Ammonium And Nitrite Nitrogen Transformation In Soils, Virupax C. Baligar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations were carried out to study the effect of alternate wetting and drying cycles on the mineralization, nitrification, and denitrification of soil nitrogen in two soils, in the presence or absence of added ammonium and nitrite. Soils were analyzed at the end of each drying cycle for total inorganic nitrogen, ammonium, and nitrite nitrogen. Gaseous products, i.e., ammonia, and the oxides of nitrogen (NO and NO₂) were collected in the course of drying for determination.

The drying cycles accelerated the rate of nitrogen mineralization in both soils and further increased the oxidation of applied and available ammonium. The …

It includes a table of plants which may be irrigated with water of varying degrees of salinity and lists precautions which should be taken for each group.

Consideration Of Macro-Climatic And Macro-Biotic Change In The Ozark Highlands During Post-Glacial Times, Kenneth W. Cole

Journal of the Arkansas Academy of Science

Climatological, pedological and faunal investigations conducted in the Upper Midwest and the Ozark Highlands indicate that the environment to which man in the Ozarks was adapting over the past 12,000 years has undergone several major shifts, beginning with a cool-moist boreal forest situation followed by a period of warming and aridness resulting in prairie and deciduous forest climaxes and subsequently, in the last 4000-5000 years, change to the pattern reflected by present conditions.
