That karst topography is topography dominated by features of solutional origin [10]. geomorphically, the dominant features usually but not always obviously present, are sinkholes and caves. in tropical regions, karst towers (e.g. mogotes) may also dominate the landscape.?

Microflora and activity of functional groups in the sediments of three caves of Central Italy., 1978, Fumanti B. , Pasqualini A. , Visonà L.
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 of topographic, geomorphologic, hydrologic and trophic characteristics of the caves examined.
A new Microparasellid from subterranean phreatic waters of Italy: Microcharon arganoi n. sp. (Crustacea: Isopoda)., 1978, Pesce Giuseppe L. , Tete Pierantonio
Microcharon arganoi, a new Microparasellid from subterranean waters of Southern Italy is described. For the shape and ornamentation of pleopod II of females and for the morphology of pleopod II of males, the new species is clearly related to the phyletic line which includes all the Western and French species of the genus. However, from all these species and from all the other ones M. arganoi differs by the ornamentation of the antennae, maxillipeds and pereiopeds, by the shape and ornamentation of pleopods I and II of males and II of females. and by ratio endopod/exopod of pleopod III. The new species is the first one from the subterranean freshwaters of Italy.
The Role of CO2 In Gypsum Speleogenesis: First contribution., 1981, Forti Paolo, Rabbi Ernesto
Starting from direct observation carried out inside gypsum caves around Bologna (Italy), the authors develop a new theory about the role played by CO2 in gypsum karstification. Such a theory agrees with the presence of calcite sinters inside gypsum caves without any source of calcium carbonate (cover or interbedding layer). Moreover, starting from this theory, gypsum speleogenesis has to be always considered as a hyperkarstic phenomenon (more than 3 components at the equilibrium).
Absolute Population Censuses of Cave-Dwelling Crickets: congruence between mark-recapture and plot density estimates., 1982, Carchini Gianmaria, Rampini Mauro, Sbordoni Valerio
The absolute size, N, of a Dolichopoda geniculata population was estimated both by the Lincoln-Petersen index and the total count on sample plot methods in a natural cave in Central Italy. 19 pairs of estimates, obtained over 2 years, exhibit a seasonal pattern and a mean value of N ? 430. Differences between estimates obtained with the 2 methods are not significant (P > 0.8). These results, and data from the literature enable most of the major factors influencing the two types of estimates to be identified. Respective cases where methods may be preferably applied are suggested.
Strontium geochemical evidence for the origin of the barite deposits from Sardinia, Italy, 1984, Barbieri M, Masi U, Tolomeo L,
Sr content of 137 samples of barite, 81 samples of fluorite, and 65 samples of calcite from 27 post-Cambrian karst and hydrothermal deposits. Karst calcites have an average Sr content of 26 ppm, quite similar to that of the hydrothermal calcites. Hydrothermal fluorites show an average content of 56 ppm. Forty-five percent of the karst barites have an Sr content over 6,000 ppm, while as much as 83.8 percent of the hydrothermal barites contain more than 6,000 ppm Sr. The Sr isotope composition of the Cambrian stratiform barites (0.70867 or - 3) is similar to that of Cambrian seawater, suggesting that the bulk of the Sr was provided by this source. The Sr isotope ratios of the karst barite (average 87 Sr/ 86 Sr = 0.70947 or - 1) indicate that Sr was not only derived by recycling of the stratiform barite but was also provided by the noncarbonate fraction of the Cambrian wall rocks. The Sr isotope composition of the hydrothermal barites ranges from 0.70990 or - 4 to 0.71837 or - 4, suggesting that the Sr derived mainly from a high 87 Sr/ 86 Sr ratio source.--Modified journal abstract
New records for Salentinella Ruffo (Crustacea Amphipoda) from phreatic waters of Italy and Greece., 1985, Pesce Giuseppe L.
New localities for the subterranean amphipod Salentinella Ruffo from central-eastern Mediterranean are reported. New collecting localities are listed for Italy, continental Greece and islands of Cephalonie and Zante. Furthermore, some remarks are made about the systematics, the variability and the ecology of the genus. Moreover, the Author refers to the main characteristics of a Salentinella sp. from central Italy, showing intermediate features between S. angelieri and S. franciscoloi. A map of the distribution of the genus Salentinella in Italy and in the Balkan-Dalmatian Peninsula is enclosed.

Relationships between the internal and external evolution of the Monte Cucco Karst Complex. Umbria, Central Italy., 1987, Guzzetti Fausto
The relationships between the internal and external evolution of the Mt. Cucco karst complex are studied. A classic set of equations, involving the oxidation of hydrogen sulphide, originated at depth in an evaporitic formation, is used to explain the presence of massive gypsum deposits in the Mt. Cucco and the Faggeto Tondo caves. The distribution and the morphology of more than 30 caves in the system, the presence of gypsum, always located along faults, and the presence of broken stalactites and columns, suggest that the evolution of the karst system has been controlled by tectonic movements. Relationships between the development of the caves and the geomorphic evolution of the area are proposed.

Paleokarst - a Systematic and Regional Review, 1989,

Description
Prepared by some of the world's leading experts in the field, this book is the first summarizing work on the origin, importance and exploitation of paleokarst. It offers an extensive regional survey, mainly concerning the Northern Hemisphere, as well as a thorough analysis of the problems of research into paleokarst phenomena, with particular emphasis on theoretical contributions and practical exploitation. By concentrating on phenomena which have appeared in the course of geological history, the book represents a substantial development in the general theory of paleokarst and demonstrates the advantages of a comprehensive approach to the problem. Considerable emphasis is put on the economic importance of paleokarst phenomena, from the point of view of exploiting significant deposits of mineral raw materials, as well as from a civil engineering and hydrological point of view. Since the publication deals with a boundary scientific discipline, it is intended for specialists from various branches of science: geologists, paleontologists, economic geologists, geographers, mining engineers and hydrogeologists.

Secondary sympatric occurrence of sibling species of subterranean shrimps in the Karst., 1990, Sbordoni Marina Cobolli, Matthaeis Elvira De, La Rosa Giuseppe, Mattoccia Marco, Sbordoni Valerio
Allozyme variation at 32 gene loci was studied in cave dwelling shrimps of the genus Troglocaris (fam. Atyidae). Populations were collected from several caves and wells belonging to different drainage systems in the Karst areas of NE Italy. Results suggest the existence of two sympatric, genetically distinct, biological species (provisionally indicated as species A and B in the T. anophthalmus complex) in the samples collected at the Duino Well, Sagrado and Comarie caves (Nei's D = 0.209). Samples from Gradisca and Aurisina are represented by only one (A) or the other (B) of the two species, respectively. Two remaining eastern populations from the Rosandra Valley also proved to be monospecific. However, they posses fixed alternative alleles markedly different from both species A and B suggesting that these two populations may belong to a third sibling species, C (A vs. C, D=0.346; B vs. C, D=0.146). These data are discussed in relation to allopatric speciation of cave dwelling shrimp species, flooding periods of subterranean waters and the role of cave organisms as markers of this process.
