Studies On The Biology Of Oligochaetes From The Phreatic Water Of An Exposed Gravel Bed, Michael Ladle
Studies On The Biology Of Oligochaetes From The Phreatic Water Of An Exposed Gravel Bed, Michael Ladle
International Journal of Speleology
More than twenty species of oligochaeta belonging to the families Enchytraeidae, Naididae, Tubificidae and Lumbriculidae were found in the phreatic water of the river bank gravels. Psammoryctes barbatus, Rhyacodrilus coccineus and Styludrilus heringianus were found throughout the year, attaining maturity in the spring. These three species may be univoltine under these conditions. The family Naididae and a few species of Tubificidae show well marked seasons of abundance, chiefly in the summer and autumn.

The Subterranean Fauna Associated With The Blind Palaemonid Prawn Typhlocaris Galilea Calman, Moshe Tsurnamal, Francis Dov Por
International Journal of Speleology
Exploration of the subterranean tract of the spring of En-Nur (at the North end of Lake Tiberias) by scuba diving and by use of new collecting methods, led to the discovery of a living community associated with the blind prawn Typhlocaris galilea. A rich growth of sulphur bacteria and of pigmentless Cyanophyceae from the trophic basis in this peculiar biotope. Representatives of three hypogeic crustacean orders have been found as well as some peculiar gastropods, nematods and oligocaets. The latter are the main food of Typhlocaris galilea.
A New Cave Amphipod Crustacea From Japan, Masuzo Uéno
A New Cave Amphipod Crustacea From Japan, Masuzo Uéno
International Journal of Speleology
A new eyeless Amphipod Crustacea 5 mm long was found in Himisé-dò Cave in Tokushima Prefecture, Shikoku. The inner ramus of its third uropod is nearly as long as the unijointed outer ramus. The accessory flagellum of the first antenna consists only of a single joint. The first maxilla is distinctive in its small palp which does not extend beyond the apical margin of the outer plate and bears only an apical seta. In these characteristic features the present form is different from any known species of the genera of the Crangonyx and Hadzia groups and seems to belong to …
Food And Feeding Habits Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell
Food And Feeding Habits Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell
International Journal of Speleology
Food and feeding habits of a population of the troglobitic carabid beetle Rhadine subterranea inhabiting Beck’s Ranch Cave, Williamson Co., Texas, were investigated. Observational and experimental data demonstrate that a primary food source of this beetle is the eggs of cave crickets (Ceuthophilus spp.). The beetles locate eggs by selective digging into substrata where cave crickets have oviposited. Chemoreception and mechanoreception are important in the location of oviposition sites.
Preference Responses And Tolerances Of The Troglobitic Carabid Beetle, Rhadine Subterranea, Robert W. Mitchell
Preference Responses And Tolerances Of The Troglobitic Carabid Beetle, Rhadine Subterranea, Robert W. Mitchell
International Journal of Speleology
Studies were made on the preference responses and tolerances of the troglobitic carabid beetle Rhadine subterranea to light, temperature, and relative humidity. The beetles are weakly photonegative and appear to have a strong preference for atmospheres of low saturation deficit. Both these responses seem to be orthokineses. They have a strongly developed temperature sense, and their temperature preferendum shifts seasonally. This response seems to be a klinotaxis. They are neither strongly stenothermal nor stenohygrobic. The preference responses, especially that of temperature, are probably mechanisms tending to restrict the beetles to their habitat. The tolerance data suggest that the epigeum could, …
A New Species Of The Subterranean Amphipod Genus Allocrangonyx (Gammaridae), With A Redescription Of The Genus And Remarks On Its Zoogeography, John R. Holsinger
A New Species Of The Subterranean Amphipod Genus Allocrangonyx (Gammaridae), With A Redescription Of The Genus And Remarks On Its Zoogeography, John R. Holsinger
International Journal of Speleology
The systematics of the North American, subterranean amphipod genus Allocrangonyx are revised and two species are recognized - A. pellucidus (Mackin) and A. hubrichti, new species. Allocrangonyx is critically compared with the European genus Niphargus and several endemic North American genera of the Crangonyx group. Because of its unique morphological position, Allocrangonyx is removed from the Crangonyx group and placed in the newly designated AlIocrangonyx group. Some factors believed to have influenced speciation within the genus are discussed in some detail.

Durées De La Mue, De L'Intermue Des Adultes, Et Longévité De Stenasellus Virei Dollfus (Crustacé Asellote Troglobie), Guy Magniez
International Journal of Speleology
The author’s observations of numerous cases of molting in the hypogean asellid Stenasellus virei Dollfus, 1897 appear to show that the phenomenon occurs in two steps. The loss of the anterior exuvium is separated from that of the posterior exuvium by a period of 8 to 16 days in adults from cavernicolous populations of Stenasellus virei in the Pyrenees and Cantabrian Alps. The intermolts last from 9 to 18 months for the same individuals. One must allow, for this species, a minimun life span of 10 years. Values of the same order of magnitude are anticipated for the two other …

Die Isopoda Terrestria Der Höhlen Von Ereğli Am Schwarzen Meer (5. Beitrag Zur Kenntnis Der Türkischen Isopoden), Hans Strouhal
International Journal of Speleology
Dr. Klaus Dobat (Tübingen) and Madame Dobat have collected the following terrestrial Isopods from caves of Eregli on the coasts of the Black Sea, North of Turkey: 1) Ligidium (Ligidium) assimile sp. nov., trogloxene widely distributed in the northern Anatolian territories; 2) Chasmatoniscus oculatus gen. et sp. nov., troglophile; 3) Trichoniscus (Trichoniscus) heracleotis sp. nov., troglobic; 4) Cylisticus (Platycylisticus) dobati subgen. et sp. nov., troglophile; 5) Cylisticus (Cylisticus) mechthildae sp. nov., troglobic. The author gives the descriptions together with figures of all these new Oniscoidea in this paper, M. Dobat describes the caves of Ereğli and lists the animals herein …
Distribution And Dispersion Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell
Distribution And Dispersion Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell
International Journal of Speleology
Intracave distribution and dispersion patterns within a population of the troglobitic carabid beetle Rhadine subterranea were studied. Distribution was markedly heterogeneous, the beetles being almost entirely restricted to substrata of deep, uncompacted silt. Dispersion of the beetles on the silt substrata did not depart from random expectation. It is shown, however, that this is a functionally emergent pattern resulting from an intrasex repulsion related to feeding which tends to produce regularity counterbalanced by an intersex attraction related to reproduction which tends to produce contagion.
