Microflore Et Activité De Groupements Fonctionnels Dans Les Sédiments De Trois Grottes De I'Italie Centrale, A. Pasqualini, B. Fumanti, L. Visonà

International Journal of Speleology

A comparative study is presented of the microflora of sediments in three caves with different trophic characteristics. Quantitative and qualitative variations of microflora were investigated for one year by studying the total microflora and the activity of the nitrogen cycle functional groups. Data were compared with those of other works of previous authors. Results show that the quantity and kind of organic matter of sediment are most important factors regulating the abundance and activity of cavernicolous microflora. The experimental part of this paper is prefaced by a digest of investigations previously carried out on cavernicolous microflora and by a report …

Ecological Investigations Of The Influence Of A Polluted River On Surrounding Interstitial Underground Waters, Milan Meštrov, Romana Lattinger-Penko

International Journal of Speleology

Because of the fundamental biological investigations and also of the practical importance, the authors investigated interstitial subterranean water (hyporheic) near a polluted river Sava in the plain where the underground waters are considered as potable. With the comparison of the physical, chemical, bacteriological, saprobiological and faunistic characteristics of the river and its hyporheic zone in different seasons their mutual relation is detected. The results show the influence of polluted river water on the hyporheic water within the river bed to at least 2 m depth.

Primary Productivity In Hillsborough Bay, City Of Tampa Department Of Sanitary Sewers

Reports

This study was designed to be a long term ecological study. Effects of nutrient removal through time on productivity is expected to be shown.

As the treatment progresses from primary to secondary, to nitrification, to denitrification, we expect to be able to document corresponding drops in productivity levels.

Nitrobacter In Mammoth Cave, C. B. Fliermans, E. L. Schmidt

International Journal of Speleology

Mammoth Cave, a large limestone cavern in Mammoth Cave National Park in the Central Kentucky karst, was first mined for saltpetre in 1808 and was a major source of nitrates used in the manufacture of gunpowder during the War of 1812. The mechanism of saltpetre formation is unknown, although hypotheses encompassing both biotic and abiotic functions have been suggested. Present studies were conducted in various saltpetre caves using species specific fluorescent antibodies in order to determine if the chemoautotroph, Nitrobacter, were present. Population densities and species distribution of Nitrobacter were studied in relation to chemical and physical parameters for …
