Sur La Faculté D'Absorption De Substances Colorées Par La Cuticule De Caecosphaeroma Burgundum Dollfus, Crustacé Isopode Des Eaux Souterraines, François Graf, Claude Marvillet
International Journal of Speleology
The discovery, in certain subterranean waters, of “pigmented,” brown or black Caecosphaeroma burgundum, led to the systematic study of the action of pigmented substances on these crustaceans. The results of these experiments demonstrate that the colorations thus obtained or observed in nature are due to the agglutination of coloured substances on the surface of the carapace and, in certain cases, to an impregnation of the cuticle itself.

A New Species Of Gomphonema (Bacillariophyta) From Mammoth Cave, Kentucky, Sam L. Van Landingham
International Journal of Speleology
In some materials collected from Mammoth Cave, Kentucky, a diatom was found which could not be identified with any known species. A taxonomic description of Gomphonema hotchkissii nov. spec. is given.

Die Ökologische Stellung Der Höhlen-Und Spaltengewässer Innerhalb Der Subterranaquatilen Lebensbereiche, Siegfried Husmann
International Journal of Speleology
Bodies of waters in caves and in crevices of rocks are distinguished from the other subsoil water ecosystems (“eustygon”, “stygorhithron”, “stygopotamon”) under the names “troglostygon” and “petrostygon”. The colonisation of subsoil water biotopes involves a fundamental principle which controls the development of the main biotopes for the stygobiont undergroundwater organisms. According to this ecological rule, which is described in detail and formulated, the several interstitial biotopes (for example “eustygopsammal,” “rhithrostygopsammal,” “potamostygopsephal”) are to be considered as the real biotopes of the stygobiont subsoil water organisms; waters in caves, on the contrary, are secondary biotopes of these animals. Caves which contain …

International Journal of Speleology
Chromatographic analysis of the yellow organs of the fresh-water Isopod Crustacean Caecosphaeroma burgundum Dollfus revealed, through observation of the chromatograms in ultraviolet light, the occurrence of both absorbing and fluorescent substances. Among the latter, only isoxanthopterin has been identified. The yellow pigment, which probably has a pteridine nucleus, could not be identified as a known compound and will be the object of later investigations.

International Journal of Speleology
The feeding behaviour of the blind cave fish Anoptichthys is characterised by two phases, an initial short chemioreceptic one and second one in which the fish explores the bottom systematically for a longer period. The whole process last approximately 30 seconds, both in adults as in youngsters.

Algal Growth Experiments In The Baradla Cave At Aggtelek (Biospeleologica Hungarica Xxi), Erzsebet Kol
International Journal of Speleology
The author kept 108 algal strains (Cyanophyta 53, Chlorophyta 35, Chrysophyta 20), of axenic cultures from the Kol-Algotheca in the Botanical Division of the Hungarian National Sciences Museum in the Baradla Cave, at Aggletek (Hungary) in darkness for 204-420 days under different environmental conditions. The experiments have proven that several algal strains can tolerate well the complete absence of light. Furthermore, that some algal strains show intensive development even under such conditions. These axenic cultures kept in the cave in metal boxes on inorganic medium have shown that the energy source used by these green coloured algae is not …
