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.

Diploures Campodéidés Des Grottes Du Pendjab (Simlacampa Clayae), C. Bareth, B. Condé

International Journal of Speleology

Four new specimens of Simlacampa clayae Condé, found in two caves in Pundjab (India), give opportunity to improve the original diagnosis and to describe two males and one immature.

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.

Note On Lepidoptera From Bulgarian Caves, Andrzej W. Skalski

International Journal of Speleology

This paper is a report on Lepidoptera collected in 1960 and 1970 in some caves of the Lakatnik region in the Stara Planina Mts. (Bulgaria). The following species were found: Digitivalva granitella (Tr.), D. pulicariae (Klim.), Thiphosa sabaudiata Dup. and Autophila limbata Stgr.

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 …

Observations Sur Un Aselle Obscuricole De France: Proasellus Racovitzai N.Sp. (Crustacea Isopoda Asellota), Jean-Paul Henry, Guy Magniez

International Journal of Speleology

This paper reports the description of a new species of the genus Proasellus Dudich. Proasellus racovitzai n.sp. is widely depigmented. The eyes are reduced. It lives in the underground stream of the Goueil-di-Her cave system (Haute-Garonne, France). The species is an old, endemic form of the phyletic line of the modern epigean species P. meridianus (Racovitza). Chromosome number of the new species: 2n = 22.

Biospeologica Sovietica.Xlix. Le Premier Représentant Anophtalme Des Trechini (Coléoptères Carabiques) De La Ciscaucasie, S. I. Ljovuschkin

International Journal of Speleology

During a recent exploration of caves in western Ciscaucasia there was collected, among others, a new species representing a new genus of Trechini (Coleoptera, Caraboidea), the description of which is given here; it has been named Birsteiniotrechus ciscaucasiens n.gen., n.sp., in memory of Prof. J.A. Birstein, famous Soviet biospeleologist, the founder and promotor of the “Biospeologica sovietica” series who passed away recently (cf. I.J.S., 4, part.2). The interest of Birsteiniotrechus lies in the fact that, until now no troglobite or endemic species of Trechini was known from the Ciscaucasian mountains; this genus belongs to the phyletic series of Neotrechus and …

A reference list containing 55 titles has been attached.

A New Genus Of Bulgarian Cave Spiders (Protoleptoneta Bulgarica N.G., N. Sp., Leptonetidae), Christo Deltshev

International Journal of Speleology

A new genus Protoleptoneta (P. bulgarica n. g., n. sp.) is described, which was collected in caves of the Western Balkan mountains - Bulgaria. The new genus unites features of the genera Leptoneta and Paraleptoneta but there are many differences, which divide it from these genera. It differs from Leptoneta as follows: the tarsus of male palp does not possess the characteristic apophysa of Leptoneta; the tarsus is less depressed and does not branch out; the teeth of chelicerae are equable and equidistant. It differs from Paraleptoneta as follows: the femora of male palp is spineless; near the …

Biospeologica Sovietica L: Une Nouvelle Espèce Cavernicole De Harpolithobius (Chilopoda, Lithobiidae) Du Caucase, Harpolithobius Birsteini N.Sp., N. T. Zalesskaja

International Journal of Speleology

A new troglobite species belonging to the genus Harpolithobius has been discovered during a recent biological exploration of Caucasian caves; 1 male and 2 females were collected in Avidzba cave and are described here. 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 …

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 …

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.

Capillary-Diffusion And Self-Diffusion Of Liquid Water In Unsaturated Soils, Ronald E. Phillips, V. L. Quisenberry Jr.

KWRRI Research Reports

Capillary-diffusion coefficients were measured by use of inflow and outflow methods. With both methods the capillary-diffusion coefficients decreased very rapidly with decreasing water content. The lighter textured soils were found to have the higher diffusion coefficients over the entire moisture content range studied, 0 to 1 bar tension.

Self-diffusion coefficients were measured over a moisture content range from air dryness to saturation using ³H as a tracer of water. Each of the soils gave the same diffusion characteristics when the self-diffusion coefficients were expressed as a function of either water content or average number of water layers on the …

Precambrian Geology Of The Central Nacimiento Mountains, Sandoval County, New Mexico, Kent Richard Reed

Earth and Planetary Sciences ETDs

The oldest Precambrian rocks in the area of study are represented by abundant inclusions and schlieren of horn­blendite, plagioclase-hornblende schist, and plagioclase-­hornblende-biotite schist. These inclusions are remnants of a pre-batholithic metamorphic terrane.

The next oldest, and dominant rock in the central Nacimiento Mountains is gneiss that ranges in composition from quartz monzonite to granodiorite. Where strongly sheared, the rock is microcline-biotite-quartz-plagioclase schist. Gradational zones of schist within the gneiss were mapped separately. The gneiss and the schist are cut by metamor­phosed spessartite dikes and by leucocratic dikes of various textures and compositions.

Intruding the gneiss in the southeastern part of …

Gravity Investigations Over A Salt Structure Near Lübbecke, Northern Germany, Reinhard K. Frohlich

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

A detailed gravity survey was conducted parallel to the “Wiehengebirge” northwest of Minden in Northern Germany. The survey localized between Liibbecke and Levern a salt deposit, which is known as “Münder Mergel” salt of the Upper Jurassic. The salt deposit forms a cylindrical structure with an axis striking NWW. With a deep drill hole detailed interpretation was possible using the polygon method of TALWANI, WORZEL and LANDISMAN [1959], The section shapes of salt bodies under eight profiles show asymmetrical figures of two salt units. Both increase in thickness strongly to the northeast, where the salt is interrupted by a fault …

An Evaluation Of A Stable Isotope Of Dysprosium For Labeling And Tracing Sedimentary Particles, Charles Glenn Boone

OES Theses and Dissertations

An evaluation of the application of dysprosium oxide as a tracer coating to surface label sedimentary particles is made. Physical and chemical properties of the labeled sand are studied. Effective diameters and settling properties of the tracer sand are compared with unlabeled sand. A total of 8.51 kg of labeled sand was placed on the beach at Camp Pendleton. Dispersal patterns obtained 1 and 4 hours after tracer injection indicate a general down current mean tracer migration rate of 0.21 cm/sec (0.42ft/sec). An absolute detection limit of 4 or 5 parts per 100,000 and a real detection limit, after field …

Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela

Dissertations and Theses

A fault-like linearity along the lower Clackamas River is evaluated by analysis of physiographic and structural alignments, geological relationships, and by gravity and magnetic data. The study has resulted in the verification of a structural feature extending along the Clackamas River and the eastern front of the Portland Hills.

Physiographic alignments were examined in twelve 15 minute and two 7-1/2 minute quadrangle maps. A significant northeasterly morphologic trend, N. 20⁰ W. and N. 40° W., and other secondary trends, namely, the N-S, E-W, and N. 50-60° E., has developed in the Portland area. The consistent northwest trend is observed throughout …
