Biospeologica sovietica. XLIX. The first troglobite representative of Trechinae (Coleoptera, Carabidae) in Ciscaucasia., 1972,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Ljovuschkin S. I.
During a recent exploration of caves in western Ciscaucasia there was collected, among others, a new species representing a new genus of Trechini (Coleoptera, Caraboidea), the description of which is given here; it has been named Birsteiniotrechus ciscaucasiens n.gen., n.sp., in memory of Prof. J.A. Birstein, famous Soviet biospeleologist, the founder and promotor of the "Biospeologica sovietica" series who passed away recently (cf. I.J.S., 4, part.2). The interest of Birsteiniotrechus lies in the fact that, until now no troglobite or endemic species of Trechini was known from the Ciscaucasian mountains; this genus belongs to the phyletic series of Neotrechus and is nearly allied to Troglocimmerites, but differs from it by its labial characters.

Description of three eyeless and apigmented new species of Trichoniscidae which have been found in Su Mannau cave in Sardinia. Two of them belong to the genus Catalauniscus Vandel: Catalauniscus hirundinella n.sp. offering few relationships with the spanish species C. espanoli Vandel, and Catalauniscus puddui n.sp. which has also similar features to an iberian form, C. bolivari Arcangeli. The third (Scotoniscus janas n.sp.) belongs to the endemic genus Scotoniscus Racovitza, until now monospecific and represented by a series of subspecies from the Northern Pyrenees, all nearly related to the specific form S. rnacromelos Racovitza. The discovery of those three new species brings forward additional arguments to the thesis of a Tyrrhenian origin of these taxa of Trichoniscidae.

This paper is the second in the three part series dealing with the evolution of the North American isopods of the genus Asellus. The generic status of Asellus is discussed with emphasis placed on the newly proposed genera of Henry and Magniez (1968). Use is made of comparative anatomical and where feasible statistical methods during this investigation. The first, shorter portion of the study deals with the presentation of evidence supporting the viewpoint that if 'Pseudobaicalasellus" is to be considered a valid genus then it must include the members of the Cannulus Group of Steeves (1965). The second portion of the study is concerned with the determination of the generic status of the eastern North American isopods. From the data presented it is felt that it is inadvisable to elevate species; groups of Asellus to the rank of genera. A generic diagnosis of the genus Asellus is presented. A list of North American species of the genus Asellus as well as a key to North American species of Asellus is included. The reduction to synonymy of certain nominal species of the genus Asellus is also given.

Cavernicolous Pseudoscorpions from Macedonia., 1974,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Curcic Bozidar P. M.
A cavernicolous pseudoscorpion of the genus Neobisium Chamberlin 1930 is living in Kalina Dupka cave in the Bistra Highland of western Macedonia. This pseudoscorpion clearly differs from the other members of the subgenus Blothrus Schiodte 1849, and belongs to the new species N. (B.) princeps, the principal features of which are described in this study. The nearest relatives of this species are N. (B.} spelaeum (Schiodte) 1849, and N. (B.) stygium Beier 1931, both from Slovenian and Croatian caves. From chelal dentition N. (B.) princeps may be considered as the most primitive element of the princeps-stygium-spelaeum series. This new species is in a subterranean mode of life of extreme specialization. Relating to biogeography, it belongs to the endemic pseudoscorpion fauna in Macedonia. After finding pseudoscorpions in Zmejovica cave (Porece mountainous area), we confirmed the presence of the species N. (E.) karamani (Hadli) 1929 in west Macedonia. Morphologic analysis of male specimens from that new locality enabled us to complete description of this species previously based on a single female specimen. The comparison of Hadzis species with N. (E.) remyi Beier 1939 from west Serbian caves, with N. (E.) brevipes (Frivaldsky) 1866 and N. (E.) leruthi Beier 1931 from Turda and Bihar caves in southern Carpathians, leads to the conclusion that these pseudoscorpions belong to a closely related species group. Judging by actual distribution of these species, the possibility exists that a wide area in the ancient Balkanic dry land had been populated by the initial form of that series. As for its preferences for habitat N. (E.) karamani is an exclusive inhabitant of subterranean environment. Relating to biogeography, it may be considered as a relic of Mediterranean Tertiary fauna and its endemic differentiation as developed under the conditions of the evolution of karst relief in southern countries of the Balkan Peninsula. In conclusion, from actual knowledge and the results of this study caves in Macedonia are inhabited by three endemic species of pseudoscorpions of genus Neobisium (Blothrus), namely: N.(B.) ohridanum Hadzi 1940,N. (B.) karamani (Hadzi) 1929, and N. (B.) princeps Curcic 1974. Judging by known blothroid pseudoscorpions, it is possible Macedonia represents one of the centres of origin and genesis for autochthonous and residual fauna of the Tertiary age.

Bridge, P. J.

A study of the distribution of Macroderma remains in the caves of the southwest of Western Australia has shown greater past bat concentrations than previously recorded and that the distribution of skeletal remains and guano piles indicates a series of expansions and contractions of the Macroderma range during the Holocene.

A Triple Dye Tracing Experiment At Yarrangobilly, 1976,

Rhodamine WT, leucophor HBS and fluorescein were inserted into Deep, Eagles Nest and Traverse Creeks respectively, all sinking wholly or partly into the limestone at Yarrangobilly, as part of a program to determine the catchment area of Hollin Cave. Hollin Cave and three other major springs, together with the Yarrangobilly River above, between and below these springs, were sampled for various periods manually or by machine. Heavy rains began a day after dye insertion. Various lines of evidence and analysis, including the plotting of regression residuals between different wavebands as time series, showed that the relevant fluorescent wavebands were affected by rises in natural fluorescence in the runoff, probably of organic origin. Green was affected most, then blue, and orange only slightly. It was possible to identify a dye pulse of rhodamine at Hollin Cave, most probably representing all the dye put in. A leucophor dye pulse was also identifiable here but a load curve could not be constructed because of probable interference by changing natural fluorescence. Tracing by fluorescein became impossible. Interference between the three dyes was demonstrated. The implications for future quantitative tracing here are discussed.

Locomotor responses of the cave fish Astyanax jordani (Pisces, Characidae) to periodic and aperiodic light and temperature signals., 1978,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Thins Georges, Weyers M.
The locomotory activity of adult cave fishes Astyanax jordani was recorded in isolation in the following light and temperature conditions: constant conditions (100 Lx; 200C), in a light cycle (LD:11/11 -10 Lx -100 Lx) and in a temperature cycle (11/11; 17/20, 19/22, 20/23, 27/30 C). All longitudinal time series extended for a minimum of 30 days. Results show: (1) That no circadian regulation appears in constant conditions; (2) that passive entrainment occurs in LD (Amplitude: 90 Lx) and in periodic temperature conditions (Amplitude: 3C). The entrainment effect damps out and varies individually; (3) that the mean activity increases with temperature; (4) The adjustment of activity to periodic signals is individually stable. These results suggest that A. Jordani is devoid of any endogenous oscillator of the circadian type. The observed thermal adaptation could have the following functions: (1) To increase the level of activity in function of the thermal level under the form of passive entrainment; (2) To enhance the exploratory behaviour of the fish in search of a thermal preference allowing the animal to keep inside a well defined zone of the subterranean biotope in relation to small local temperature changes.
