A series of 9 trials to compare the crossbred subterranean clovers Nungarin, 239.2 and 584.1B. with Northam and Geraldton was sown in representative, dry wheatbelt localities in 1976. The trials were sown in randomised blocks with four replications on sites which carried little or no clover. Plot size was 4.22 metres by 40 metres. Superphosphate was applied at rates related to past applications and soil type, but was usually about 200 kg a hectare. Copper, zinc and molybdenum were applied where necessary. Seed …

Review Of The Oligocene Cetacea, Frank C. Whitmore Jr., Albert E. Sanders
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 …
The Distribution Of The Fauna In The Interstitial Habitats Of Riverine Sediments Of The Danube And The Piesting (Austria), Dan L. Danielopol
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 …

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

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 …
New Data On The Foraminifera Of The Groundwaters Of Middle Asia, V. I. Mikhalevich
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 …
An Introduction To The Japanese Groundwater Animals With Reference To Their Ecology And Hygienic Significance, Kôichi Matsumoto
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 …

The Effect Of Cave Entrances On The Distribution Of Cave-Inhabiting Terrestrial Arthropods, Stewart B. Peck
The Effect Of Cave Entrances On The Distribution Of Cave-Inhabiting Terrestrial Arthropods, Stewart B. Peck
International Journal of Speleology
Populations of cave invertebrates are generally considered to be food-limited. The cave entrance is a major source of food input into the community in the form of decaying organic matter. Thus, the densities of scavenging terrestrial cave invertebrates should be related to the distance from the cave entrance because this represents a measure of food abundance. A test showed this expectation to be true in Crossings Cave, Alabama. A population density peak occurred 10 m inside the cave where the dark zone and detritus infall regions meet. The greatest population peak occurred at 100 m where densities of crickets and …
Les Adaptations À La Volvation Du Squelette Externe De La Tête Chez Caecosphaeroma Burgundum Dollfus, Crustacé Isopode Des Eaux Souterraines, C. Marvillet
International Journal of Speleology
The study of the cephalic capsule of Caecosphaeroma burgundum, a subterranean waters Isopod, demonstrates improved adaptations to volvation; these concern in a similar manner the other regions of the body, particularly the pleotelson. From a primitive aquatic Isopod structure, the head of this blind Spheromid has been completely fashioned by many mechanical factors: posterior margin of pleotelson providing support on the head, relation of anterior angles of the second pereionit and, above all, the mandibular palps and antennae which retract into two deep grooves of the face. The comparative study of the head of other volvational Isopods shows the …
Recent Karyological Research On Cave Planarians From Europe, Nicole Gourbault
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.

The Effect Of Recreational Uses On Vegetation And Soil In The Buffalo Campground, Targhee National Forest, Island Park, Idaho, Susan Daines Foster
Theses and Dissertations
The effect of trampling on vegetation and soil, as a result of recreational pressure, was studied in the Buffalo campground of the Targhee National Forest, Idaho. Site deterioration was most evident in the forty-two year old site. The tree stand had matured, but there were few young trees and tree reproduction had been reduced to ten seedlings per acre for Pinus contorta. Only two shrub species were sampled with a combined population of eight individuals per acre. Most of the grass species had been seeded; forbs provided 20% of the ground cover, 13% was bare ground and 71% litter. The …

Climatic factors, feedlot runoff, and organic material in the runoff were evaluated in experimental and commercial feedlots. The effects of slope, stocking rates, terraces, basins, and holding ponds were evaluated to obtain the best controls for containing runoff. In eastern Nebraska, 70 cm annual precipitation produces 23 cm of runoff; whereas, in northeastern Colorado, 37 cm annual precipitation gives only 5.5 cm of runoff. Large applications of runoff liquid, up to 91 cmon grass-Ladino and 76 cm on corn, in Nebraska did not decrease yields; however, in northeastern Colorado, the concentrated high-salt runoff required dilution before direct application to crops. …

Residual Nitrogen As It Affects Soil Fertility Under Irrigated Agriculture In A Tropical Wet-Dry Climate, Don Carlos Kidman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the Zapotitan Valley near San Andres, El Salvador, Central America, an experiment was conducted to determine the availability of residual soil N to corn grown during the rainy season. This was an extension of an experiment conducted during the preceding dry season. The variables of the dry season experiment were irrigation method, crop, and rate of fertilizer N application. Soil NO3-N and NH4-N were determined by soil sample analysis to a soil depth of 120 cm by 30 cm depth increments. The samples were taken at the end of the dry season experiment and again …
