Report, The Food Habits And Nesting Success Of Wood Storks In Everglades National Park In 1974, 1978, John C. Ogden, James Thomas Tilmant, James A. Kushlan
Audubon’s Everglades Science Center - Records
This report is on a study of the ecology of the Wood Stork (Mycteria americana) in the Everglades National Park, conducted from September 1973 to June 1974. The wood stork is an important link in the food chains of the Everglades and estuarine ecosystems of southern Florida.

Bogidiella Martini, Un Nouvel Amphipode Souterrain De I'Ile Saint-Martin (Antilles) Et La Zoogéographie Des Bogidiellidae, Jan H. Stock
International Journal of Speleology
Both sexes of a new species of Bogidiella, B. martini, are described. The new species, with a very pronounced sexual dimorphism, has been discovered in two wells in the island of St.-Martin (French part), one of the Lesser Antilles. Another member of Bogidiella has been recorded from the island of Curaçao, but the specimens were damaged too much to allow proper description. The Bogidiellidae (5 genera, 26 named species, and several unnamed species) are present in the sea as well as in inland waters. The family has a wide distribution, exceeding the boundaries of the former Tethys Sea. Probably, …

Carotenoids In Niphargus Casimiriensis Skalski (Amphipoda) From Artesian Wells, B. Czeczuga, A. Skalski
International Journal of Speleology
By means of columnar and thin-layer chromatography, the presence of carotenoids in Niphargus casimiriensis Skalski from an artesian well was studied. There are qualitative and quantitative differences in the carotenoid contents of the Niphargus casimiriensis Skalski specimens.
The Tegumental Glands Of A Troglobitic Crustacean, L. Juberthie-Jupeau, Y. Crouau
The Tegumental Glands Of A Troglobitic Crustacean, L. Juberthie-Jupeau, Y. Crouau
International Journal of Speleology
Tegumental glands, located in the antennae of Antromysis juberthiei are present in males and females; in the antennulae each of them consists of 3 cells: a secretory cell of large size, an intermediary cell and a canal cell probably secretory in nature. The canal cell possesses an extracellular cavity with deep infoldings and microvilli between which the canal crinkles along. The intermediary cell is heavily provided with microfilaments. The secretory granules have an organized content.

Diplopoda From Papuan Caves (Zoological Results Of The British Speleological Expedition To Papua-New Guinea, 1975, 4), Richard L. Hoffman
International Journal of Speleology
Eight species of polydesmoid millipeds are described from the caves of the extreme northwestern corner of Papua New Guinea. Four new genera are named: in Paradoxosomatidae, Selminosoma, type S. chapmani; Astromontosoma, type A. jeekeli; in Doratodesmidae, Scolopopyge, type S. pholeter; Selminarchus, type S. hispidus. Two additional new species are referred to established genera Eustrongylosoma exiguum and Nothrosoma beroni, the latter, however, (known only from females) is probably referable to a new genus. Selminosoma chapmani appears both from its structure and biology to be a true troglobite, the first such species known in the Paradoxosomatidae. The two doratodesmid species extend the …

Magniezia Gardei N.Sp. (Crustacca Isopoda Asellote): Un Sténasellide Des Eaux Souterraines Du Maroc Sud-Oriental, Guy Magniez
International Journal of Speleology
This new species has been discovered in the waters of Kef Aziza Cave, on the Saharian slopes of the High Atlas Range, Southeastern Morocco. Magniezia gardei n.sp. belongs to the same Genus as four species previously described from the phreatic waters of the Guinean area. So, it is assumed that this Moroccan species should be a relict of the ancient aquatic hypogean fauna of the entire West Africa, nowadays protected by the development of an arid climate.
Ecological Investigations Of The Influence Of A Polluted River On Surrounding Interstitial Underground Waters, Milan Meštrov, Romana Lattinger-Penko
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.
A Critical Review Of Hypotheses On The Origin Of Vermiculations, A. Bini, M. Cavalli Gori, S. Gori
A Critical Review Of Hypotheses On The Origin Of Vermiculations, A. Bini, M. Cavalli Gori, S. Gori
International Journal of Speleology
Mud and clay vermiculations are irregular and discontinuous deposits of incoherent materials, almost ubiquitous. Found both inside and outside of caves, overlying limestone or other materials, they are formed from many substances (clay, mud, candle-black, colloidal silica, etc.). Also their shape dimensions vary greatly. The following genetical hypotheses have been proposed: fossil fillings; chemico-genetical deposition; biological formation; mechanical deposition from moving water or air; clay-layer drying process (Montoriol-Pous hypothesis); physicochemical deposition from drying liquid films. The last is proposed by the authors who, having discussed the various hypotheses, give many examples and the results of some experiments. They distinguish two …
Réponses Locomotrices Du Poisson Cavernicole Astyanax Jordani (Pisces, Characidae) À Des Signaux Périodiques Et Apériodiques De Lumière Et De Température, G. Thines, M. Weyers
Réponses Locomotrices Du Poisson Cavernicole Astyanax Jordani (Pisces, Characidae) À Des Signaux Périodiques Et Apériodiques De Lumière Et De Température, G. Thines, M. Weyers
International Journal of Speleology
The locomotory activity of adult cave fishes Astyanax jordani was recorded in isolation in the following light and temperature conditions: constant conditions (100 Lx - 20°C), 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: 3°C). The entrainment effect damps out and varies individually; (3) that the mean activity increases with …

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 …

Studies Of The Cave Crayfish, Orconectes Inermis Inermis Cope (Decapoda, Cambaridae). Part Iv: Mark-Recapture Procedures For Estimating Population Size And Movements Of Individuals, Horton H. Hobbs Iii
International Journal of Speleology
Several methods for permanently marking cavernicolous crayfishes were investigated prior to initiation of field work in Pless Cave, Lawrence County, Indiana. Internally injected ink complemented with external “painting” proved to be a most satisfactory tagging procedure. During the two-year study period 211 individuals of the troglobitic crayfish Orconectes inermis inermis Cope were marked; 96 tagged individuals were recaptured at least once, a 46% recapture rate. The population size was estimated to be 1586 +/- 79 (95% C.L.) over the 540 m subterranean stream study area and remained relatively stable during the period of 1970 to 1972. The home range of …
