The Birds Of Kentucky, Robert M. Mengel
Ornithological Monographs
The present work treats 296 species and 33 additional subspecies (329 forms in all) of birds considered by me to be valid and to have been reliably recorded within the boundaries of Kentucky from the earliest times up to and including December 31, 1960. In general, a species was considered to have been reliably recorded when (a) an extant specimen from the state has been a vailable for examination in the course of the work, (b)(1) when a specimen from the state has at some time been examined in the hand of someone capable in my opinion (2) of accurately …

Östliche Gruppe Der Monolistrini (Crust., Isoopoda): Ii.Biologischer Teil, Boris Sket
International Journal of Speleology
Following the first systematic part, in this paper the author describes the biological observations made on these Isopod Crustaceans of underground waters. The different sexual characters of the particular groups and the related differences in the behaviour before copulation are described. During the embryonic and larval development small differences between sub-genus are reported. To the differences in Caecospaeroma (according to Daum) the first and second “mancastadium” and another “postmanca stadium” with pereiopods VII not wholly formed have to be added. The author describes the growth of the different parts of the corps and the extremities, comprising the sexual characters.

Contribution À L'Étude De La Biologie D'Asellus Cavaticus Leydig (Note Préliminaire), Jean-Paul Henry
International Journal of Speleology
The cavernicole asellid Asellus cavaticus Leydig has been reared in our laboratory for more than twenty months, permitting us to give some data on the sexual cycle of this species. Females provided with brood pouches seem to be more numerous in the spring, as is the case with the subterranean amphipod Niphargus virei Chevreux. The average length of the incubation period seems much shorter than that of other troglobitic species such as Niphargus virei Chevreux or Caecosphaeroma burgundum Dollfus, so that the life cycle of our species is nearer to that of epigean Asellus. The number of young per …

International Journal of Speleology
Bats, familiar to speleologists, play an important part in animal ecology in caves. Indirectly by their guano, they provide a source of food for numerous cave-dwelling animals and directly, by their own more or less constant presence. 26 species of bats are known from Switzerland, 15 of which occur in caves. Miniopterus schreibersi is considered the only true cave-dweller. The exact distribution of the rare species, including those occurring outside caves, is found in the text and is also indicated on the accompanying maps.

International Journal of Speleology
In the cave Kaptar-Khana (south-western Turkmenistan) was discovered a lake filled with water with a salinity of 11,68‰. This lake is inhabited by a fauna of marine origin - Foraminifera (three species), Molluscs (Pseudocaspia ljovuschkini sp.n.), Harpacticoida (genera Ectinosoma, Schizopera and Nitocra), Isopoda (Microcharon halophilus sp.n.) and possibly Nematoda (Oncholaimidae). The majority of the discovered species are related to species of circum-Mediterranean origin. Geological data do not permit to consider this fauna as a relict of any of the tertiary seas. The same applies to all other cases when animals of marine origin were discovered …

International Journal of Speleology
The present note calls into question the opinion of different authors concerning the presence or lack of adult Niphargus near the phreatic table (superior layer of phreatic water) in zones prospected by Karaman-Chappuis method. Our investigations have proved the reason for which Niphargus adults were less frequent in the superior layer of the phreatic water is rather concerned with our investigation means - which are very approximate - than with the ecological or ethological requirements of these animals. The assertion that the phreatic fauna performs downward migrations during the floods must be considered as doubtful. During floods it is impossible …

International Journal of Speleology
After an introduction, comprising a historical summary on the researches on well fauna, a description of the study area in which 13 water wells have been investigated is given. The authors explain the adopted working method and indicate the physical and chemical characteristics of the waters (temperature, pH, alkalinity, hardness, O2-content, fixed residuum, suspended matter, N2O5, P2O5, NaCl, Ca, Fe). The fauna of the wells of Mehadia (see systematic part) is composed of 34 species: 1 Triclade, 3 Oligochaeta, 2 Gastropods, 5 Cladocera, 1 Ostracod, 3 Copepods, 4 Isopods, 2 …

International Journal of Speleology
The Kolyuk cave lies in the southern part of Hungary in the Mecsek Mountains, about 3 km. in distance from the village of Mànfa. The material accepted for investigation originated from a recently discovered and until now completely entombed part of the cave. It was collected by the geologist Gàbor Magyari and consisted of material scraped from the walls and ceiling of a cavity in the cave, which could be reached only by underwater swimming. From these scrapings cultures were installed with sterile Knopp solution and after the algae present in the collection reproduced, a diversified flora developed which consisted …
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, …
