A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger
A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger
International Journal of Speleology
Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …
Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu
Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu
International Journal of Speleology
Experiments were designed to test the ability of the aphotic speleoenvironment to support algal growth. The first series contained gelatin cultures of Scenedesmus placed in the cave at different localities in order to establish whether or not the microhabitats have any particular effect on the multiplication of the algae. No differences were found in the cultures after a three month incubation period in the cave, which could be traced to influences of microenvironmental conditions. Chlorella cultures in sterile Knop’s solution showed measurable growth in the cave whereas if the cultures were installed into sterilized cave water or were shielded by …

Preliminary Note On The Algae Of Crystal Cave, Kentucky, J. P. Nagy
Preliminary Note On The Algae Of Crystal Cave, Kentucky, J. P. Nagy
International Journal of Speleology
Collections of a preliminary type carried out in Crystal Cave, Kentucky, resulted in the identification of seven algal taxa. A Chamaesiphon (Dermocarpales) and an Asterocytis (Bangioidea) are reported for the first time from a speleo-environment. As no correlation could be found among the algae occurring in Crystal Cave and those of nearby Mammoth Cave the conclusion is reached that the cave algal floras do not originate from the algal vegetation of the surface but may have gotten into the caves at the time of the latter’s formation.
Algological Investigations In Mammoth Cave, Kentucky, H. J. Jones
Algological Investigations In Mammoth Cave, Kentucky, H. J. Jones
International Journal of Speleology
Algological investigations carried out in the Mammoth Cave, Kentucky, revealed the presence of twenty-seven taxa representing all divisions of the Algae except the Pyrrhophyta and Phaeophyta; diatoms although observed in the samples were not dealt with in the present paper. One species, Oscillitoria clausiana spec. nov. and a form Lyngbya pusilla fa. tenuior fa. nov., both belonging to the Cyanophyta are new to science. In addition, several other rare and interesting algae were found. A comparison is made between the algal flora of the Mammoth Cave and algae found in several European caves. The ecology of the cavernicole algae is …
Diatoms From Mammoth Cave, Kentucky, Sam L. Van Landingham
Diatoms From Mammoth Cave, Kentucky, Sam L. Van Landingham
International Journal of Speleology
Samples collected in Mammoth Cave, Kentucky, revealed the presence of a diversified but not too abundant diatom community in the cave. As the material was not subjected to culturing experiments but was investigated immediately after arrival, both in native and permanent preparations, it was possible to: 1. ascertain that the majority of the diatoms contained well developed, apparently healthy and functioning chloroplasts and 2. to get a rough estimate of the actual number of specimens present in a microhabitat. The identifications resulted in the recognition of 16 diatom taxa of which possibly 4 are new to science. Further studies are, …
