Review Of The Oligocene Cetacea, Frank C. Whitmore Jr., Albert E. Sanders

United States Geological Survey: Staff Publications

Early in the Oligocene Epoch, Cetacea of the primitive suborder Archaeoceti had already declined sharply from their apparent abundance in Eocene seas. By the beginning of the Miocene, archaeocetes are known to have survived only in the northeast Atlantic and southwest Pacific Oceans. Concurrently with this decline, the first members of the suborders Odontoceti and Mysticeti appeared. They are known from only a few specimens, mostly in upper Oligocene deposits, on both coasts of North America, in Germany, Austria, Italy, the Caucasus, Azerbaijan, Australia, and New Zealand. Two important odontocete genera, Agorophius and Xenorophus, come from beds that are …

Pleistocene Geology Of The Comstock-Sebeka Area, West-Central Minnesota, Curtis A. Anderson

Theses and Dissertations

This study is a reconnaissance of the surficial geology and a reconstruction of the late Cenozoic history of an area in westcentral Minnesota. The study area extends eastward from the Comstock area (14 miles south of Moorhead, Minnesota) in the Red River Valley to the Sebeka area (13 miles north of Wadena, Minnesota). The area is about 27 kilometres wide and 140 kilometres long.

Surface materials include Pleistocene glacial sediment and Pleistocene and Holocene fluvial, lacustrine, eolian, and bog sediment.

Four geomorphic districts are recognized. The flat Lake-Plain District is underlain by sand, silt, and clay that was deposited as …

Geology Of The Western Portion Of The Dogtooth Pluton, Lake Of The Woods Region, Southwestern Ontario, Richard H. Pilatzke

Theses and Dissertations

A 10 km2 portion of a subsolvus, syntectonic or posttectonic grano dioritic intrusion located about 16 km east of Kenora, Ontario was extensively sampled for study by petrographic modal analysis and trend surface analysis. The Dogtooth pluton, the main intrusive body sampled, is part of a granitic batholith known as the Dryberry dome, which is interpreted to have been intruded into supracrustal volcanic and sedi mentary rocks about 2480 million years ago during the Kenoran Orogeny. The Longbow pluton, which was also sampled, occurs at the west margin of the Dryberry dome in contact with the supracrustal rocks to the …

Hydrologische Und Chemische Untersuchungen An Den Fließgewässern Des Schlitzerlandes. A. Quellen. I. Übersicht, Jörg Brehm

International Journal of Speleology

In a Triassic sandstone woodland (Schlitzerland in Hesse, Western Germany) 17 springs were hydrologically and hydrochemically investigated throughout one year (April 1973 - April 1974). Measurements were carried out on water volume, temperature, electrolytical conductivity, pH, aikalinity, chlorinity, dissolved molecular oxygen, dissolved organic material (COD), ammonia, nitrite, nitrate, and free phosphate. Among the hydrochemical factors investigated the pH-value was closely related especially to the micro-climate in the spring drainage area. In particular the pH rose both with increasing length of the drainage area and — within the same spring with decreasing water supply. On the other hand the pH-value diminished …

Studies On Subterranean Drift Of Stygobiont Crustaceans (Niphargus, Crangonyx, Graeteriella), Siegfried Husmann

International Journal of Speleology

In two groundwater canals of a water work in West Germany the drift of stygobiont groundwater organisms was investigated. The collections were made at two-hour intervals. Niphargus aquilex Schiodte, Crangonyx subterraneus Bate and Graeteriella unisetigera (Graeter) were considered more closely, because they were caught in greater numbers than other organisms. These stygobionts show no sign of dial periodicity.

Die Tierische Besiedlung Des Hyporheischen Interstitials Eines Urgebirgsbaches Unter Dem Einfluß Von Allochthoner Nährstoffzufuhr, Hans-Gerd Pieper

International Journal of Speleology

The Mettma, a mountain stream in the Black Forest, W. Germany, was investigated for effects of input of nutrients and energy by domestic waste water and effluent from a brewery introduced at one specific point. The investigation time ranged from May 1970 to February 1971. Initially, there is an impoverishment and structural changes of the biocoenosis in the hyporheic interstitial. There is an almost complete O₂-depletion immediately after the waste water has been added. In winter, temperatures in the interstitial were higher than those in the current. No direct correlation between population densities and amount of organic matter …

Recent Karyological Research On Cave Planarians From Europe, Nicole Gourbault

International Journal of Speleology

Very few studies have been involved with karyology in Planarian living in total darkness. The first results indicate however, that most of the hypogeous Paludicoles have a diploid chromosome number notably superior to the similar surface forms. In another connection a relative uniformity of the morphology of the chromosome is observed in the same group, so that the studied karyotypes show a similar general aspect.

Quelques Données Sur La Population De Proasellus Slavus Ssp. N. Sket (Crustacea, Isopoda) Dans L'Hyporhéique De La Rivière Drave Près De Legrad, Romana Lattinger-Penko

International Journal of Speleology

An analysis of the population in the hyporheic medium of the Drava river shows that Proasellus slavus ssp. n. is one of the smallest known Asellids. It is living in an interstitial biotope as a permanent population in which density varies in space and time. Our observations show that reproduction takes place throughout the year, however with a maximum rate at the beginning of summer. Females may produce a relatively great number of offspring, notwithstanding the smallness of the species.

Die Vertikale Verteilung Von Ciliaten Im Stygorhithral Der Fulda (Beitrag Zur Kenntnis Mesopsammaler Ciliaten In Fließgewässern), Günther Lüpkes

International Journal of Speleology

19 species of ciliates were found in interstitial biotopes of the Fulda Headwater. Two of these were new: Haplocaulus hengsti, n.sp. and Epistylis rotti, n.sp. (Peritrichida). The number of ciliate species decreases from the surface down so deeper layers; in a depth of 50 cm, only three species were found: Haplocaulus hengsti and Epistylis rotti and another small ciliate Trachelophyllum apiculatum. There was little detritus in this layer, and so, the abundance of the ciliates was low. On the other hand, there is little predation in deeper layers of stygorhithral sand and gravel. Small, long …

The Distribution Of The Fauna In The Interstitial Habitats Of Riverine Sediments Of The Danube And The Piesting (Austria), Dan L. Danielopol

International Journal of Speleology

The interstitial fauna living in the riverine sediments of the Danube and Piesting have been investigated in Lower Austria. The nematodes, oligochaetes and cyclopoids are the most abundant groups (they represent up to 80% of the total fauna). The harpacticoids, the insect larvae, the isopods, the amphipods, the cladocera and the limnohalacarids are poorly represented (generally under 20% of the total fauna). The absence of hydrachnellids is striking. The vertical distribution of the interstitial fauna shows for several groups i.e. limnohalacarids, ostracods, isopods, harpacticoids, that the epigean species are quantitatively better represented in the upper sediment layers instead of the …

New Data On The Foraminifera Of The Groundwaters Of Middle Asia, V. I. Mikhalevich

International Journal of Speleology

New data obtained during the expedition to Middle Asia (1973) essentially enlarge our knowledge of foraminifera living in underground waters. Seven new species were discovered in the wells of the Kara-Kum and Ust-Urt deserts. All of them contain cytoplasma. The wells are situated in the region of bedding of underground waters of the heightened salinity in the zone of balance of runoff and evaporation. The majority of the species described in our work like many of the species recorded from the underground waters earlier (Brodsky, 1928; Nikoljuk, 1968; Jankovskaja and Mikhalevich, 1972) belong to the genera living in coastal brackish …

Hydrogeologische Untersuchungen In Einem Von Salzhaltigem Uferfiltrat Durchströmten Bodenkörper, Matthias Neuß

International Journal of Speleology

An aquifer in a horseshoe bend of the Weser river was investigated regarding the processes of the river water infiltration. The geology and geometry of the aquifer was ascertained by means of numerous borings. The hydraulic situation before and after infiltration was determined by water table maps. The intrusion of a salt-freshwater lens could be reconstructed from the beginning of infiltration until ten years later by means of previous results of chemical analysis. By new chemical analysis it was proved that river water infiltrates into the aquifer. Additionally it was established that the relatively high concentration of chloride is reduced …

La Dynamique De Population De L'Isopode Proasellus Slavus Ssp.N. Et Les Larves De Chironomides Dans L'Hyporhéique De La Drave Du Point De Vue De La Pollution, Milan Meštrov, Romana Lattinger-Penko, Vlatka Tavčar

International Journal of Speleology

If we sum up the data and observations derived from our researches on the Drava river, we conclude after consideration of surface water fauna and after comparison of chemical parameters that it influences the hyporheic water of a rough gravel-sandy alluvium more than 2 m deep, while in the compact sandy substratum it has less influence. The next conclusion is that the horizontal and vertical distribution of Proasellus slavus ssp.n. in the alluvium of the Drava river, depends upon the granulation of substratum, with reference so the largeness of interstices; that the populations vary in density and structure according to …

An Introduction To The Japanese Groundwater Animals With Reference To Their Ecology And Hygienic Significance, Kôichi Matsumoto

International Journal of Speleology

1) Nearly two hundred species of troglobites are known from the groundwaters of Japan. Most of these troglobiontic species, sixteen of seventy-seven genera, and what is more, four of forty-seven families are endemic to Japan. Uchidastygacaridae, Nipponacaridae, and Kantacaridae are endemic acaridan families of Japan. The coleopterous family, Phreatodytidae, is alto endemic to Japan. 2) Though studies on Protozoa, Turbellaria, Annelida, Aschelminthes, and Ostracoda, etc. remain sparse, the interstitial fauna is actively investigated recently and many specimens of Bathynellacea, Ingolfiella, Bogidiella, Microcerberus, Pseudovermis (Opisthobranchia), and Nerillidae, etc. have been collected from freshwater and marine environments. 3) None of the troglobites …

Untersuchungen Zur Funktion Des Mesopsammon Bei Der Reinigung Von Infiltriertem Oberflächenwasser, Barbara Ritterbusch

International Journal of Speleology

Based upon the hypothesis that the Metazoa (nematoda and rotifera) in the interstitial stratum of a slow sand filter are of importance in the process of purification of surface water, a filter was built to check the substrate characteristics of different grain sizes compared with the natural soil. It was found that the granulometric composition of sands as found in the settling basins did have the best comparative screening properties. This was demonstrated by chemical analyses of NH₄, NO₂, NO₃, PO₄, KMnO₄-consumption and O₂-saturation. Only the NO_{3 …}

Remarques Sur La Biologie Et L'Écologie De Stenasellus Virei Dollfus (Crustacea Isopoda Asellota Des Eaux Souterraines), Guy Magniez

International Journal of Speleology

Recent observations indicate that a laying season seems to exist, in karstic as well as in phreatic populations. Nevertheless, a single female cannot lay each year, because the reproductive intermolt averages 15-16 months and is always followed by one (9-10 months) or several non-reproductive intermolts. So, the minimum laying rhythm of female St. virei is biennial. The cavernicolous population (St. v. virei) of the Padirac swallow-hole is not a relict, but a colony separated from the main settlement of the alluvial waters of the Dordogne river. On the contrary, it is possible to find, close to each other, …

Remarques Sur L'Aselle Psammique Proasellus Walteri (Chappuis, 1948) (Crustacea, Isopoda, Asellota), Jean-Paul Henry

International Journal of Speleology

P. walteri, an eyeless species of tiny size and thin body, shows numerous original characters. By its general morphology, it is one form of Asellid best adapted to the phreatic waters where it exists in large settlements. It is also able to live in the psammic biotope in a manner similar to Microparasellids. The females lay only 6 to 10 normal sized eggs. There is no indication of oostegits outside the breeding period. In some populations, the small number of eggs, correlated with the small size, seems to be compensated by a sex-ratio favorable so the females.

The Role Of Groundwater In Eutrophication Of A Lake In Glacial Outwash Terrain, David Robert Lee

International Journal of Speleology

The nutrient contribution of groundwater in glacial outwash terrain was evaluated at Lake Sallie in north-central U.S.A. (46°46’ N., 95° 54’ W.). Groundwater entering the lake was collected with seepage meters consisting of bottomless cylinders vented to a thin membrane bag. A theoretical flow net and comparison of nutrient concentrations in well and seepage water indicated that seepage meters can be used in high velocity discharge areas to obtain site-specific water samples of groundwater for nutrient analyses. Based on an average value of 0.25 mg/l PO₄, groundwater inflow along an 800 km segment of shoreline transported 37 kg …

Über Ökologische Und Biogeographische Trends Innerhalb Der Harpacticoiden (Copepoda - Crustacea), Hans Jakobi

International Journal of Speleology

The majority of harpacticoids show a great dependence on the peculiarities of their habitat. This research attempted to detect the possible existence of biogeographical and ecological trends. The limited biogeographical data is discussed, so this is applied the method of analysis of morpho-ecological correlation (Jakobi, 1962) developed to determine ecological trends. This way, all characteristics of the harpacticoidean body selected were studied to check their adaptative value. Based on those results it was possible to establish and to define ecological units. Data were then subjected to statistical tests of homogeneity for variance and significance. Graphs are used to demonstrate the …

Systematische Untersuchungen An Grundwasserkrebsen - Eine Bestandsaufnahme (Mit Der Beschreibung Zweier Neuer Gattungen Der Familie Parabathynellidae, Bathynellacea), Horst Kurt Schminke

International Journal of Speleology

This paper reviews critically some recent work on the systematics of subterranean Crustacea, in particular Jakobi’s work on the Parastenocarididae (Copepoda), Serban’s work on the Bathynellidae (Bathynellacea, Syncarida) and Schminke’s revision of the Parabathynellidae (Bathynellacea, Syncarida). It is pointed out that three different approaches have been adopted in each of the three cases and advantages and shortcomings of each of them are analysed. Finally descriptions are given of two new genera of Parabathynellidae, Afrobathynella gen. n. and Nunubathynella gen. n., from a locality near Port Elisabeth (South Africa).

Notes Préliminaires Sur La Distribution Spatiale De Meta Menardi, Triphosa Dubitata, Triphosa Sabaudiata, Nelima Aurantiaca Et Culex Pipiens Au Sein D'Un Écosystème Cavernicole (Grotte De La Scierie: Hte.-Savoie), John D. Bourne

International Journal of Speleology

Following 8 months of observations in a richly populated cave, (Grotte de la Scierie, HauteSavoie, France), it has been possible to outline the movements and distribution of Meta menardi (Araneae), Nelima aurantiaca (Opiliones), Triphosa dubitata and Triphosa sabaudiata (Lepidoptera) and Culex pipiens (Diptera) within the cave ecosystem. Although no general rule can be postulated it appears that the morphology of the cave walls and the climatic conditions regulate the distribution of these 5 species within the cave ecosystem. The interactions between the 5 species have been investigated.
