Hydrocarbon Levels In Tampa Bay Final Report, Larry J. Doyle, Edward S. Van Vleet, William M. Sackett, Norman J. Blake, Gregg R. Brooks

Reports

The primary purpose of this project was to establish and characterize, as far as possible, hydrocarbon base levels for the Tampa Bay Estuary. In addition, we were to characterize 1) hydrocarbon molecular compositions, 2) the isotopic composition of total and lipid sediment organic carbon, and 3) evaluate the potential for utilizing isotopic analyses to quantify and determine the extent of future oil spills.

Geophysical And Hydrogeological Effects Of Astorm-Water Retention Pond On The Floridan Aquifer, Hillsborough County, Florida, Abdullah M. Alamri

USF Tampa Graduate Theses and Dissertations

An integrated geologic, hydrologic, and geophysical investigation was conducted to determine the effect of a storm-water retention pond on the Floridan aquifer. Surface DC resistivity surveys were used to delineate the hydrostratigraphy. There are four distinct geoelectric layers: (1) Layer 1, high resistivity, 3 meters thick, fine to very fine unsaturated sand; (2) Layer 2, moderate resistivity, 1 to 2.5 meters thick, saturated sands and silts; (3) Layer 3, lower resistivity, 4 to 10 meters thick, silt and clay; (4) Layer 4, moderate resistivity, argillaceous limestone. Two fracture zones are defined by resistivity lows and marked by deep, V-shaped depressions …

Hillsborough Bay Macroalgae Study Final Report, Mangrove Systems, Inc.

Reports

Hillsborough Bay. the northeastern portion of the Tampa Bay estuarine system (Fig. 1) has long suffered from the problems caused by industry and urbanization (Simon 1974). The macroalgal community of this estuary has been identified as a source of nuisance odor problems for many years. A study by the Federal Water Pollution Control Administration (FWPCA 1969) indicated that these problems resulted from degraded water quality (primarily eutrophication) which led to large populations of one or two species of marine red algae (Gracilaria spp.). Seasonal freshwater input resulted in the death and decay of these quantities of algae, producing the odor …

The Invertebrate Faunas Of Tropical American Caves, Part 6: Jumandi Cave, Ecuador, Stewart B. Peck

International Journal of Speleology

Twenty-two species of invertebrates are reported from Jumandi Cave, Napo Province, Ecuador. Three are probably trogloxenes, and the other 19 are troglophiles. The only troglobite is the catfish Astroblepus pholeter.

New Records For Salentinella Ruffo (Crustacea Amphipoda) From Phreatic Waters Of Italy And Greece, Giuseppe Lucio Pesce

International Journal of Speleology

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.

The Occurrence Of The Troglobitic Amphipod, Stygobromus Tenuis Tenuis (Smith) (Crangonyctidae) In The Taconic Mountains Of Southwestern Massachusetts (Usa): A Case For The Existence Of A Subterranean Refugium In A Glaciated Region, Douglas G. Smith

International Journal of Speleology

Stygobromus t. tenuis is one of only two species of troglobitic amphipods known to occur in the New England physiographic province. The rarity of subterranean organisms in New England is attributed to limited karst development and eradication of organisms from the region during glacial times. Traditionally it has been believed that those troglobitic species presently occurring north of the glacial terminus migrated there following glacial retreat from refugia south of the areas influenced by glacial conditions. However, a few recent studies favour the existence of subsurface refugia in glaciated regions during glacial times. Stygobromus t. tenuis is recorded from springs …

Polydesmide Et Craspedosomides Cavernicoles Nouveaux De France Et Du Maroc (Myriapoda - Diplopoda), Jean Paul Mauriès

International Journal of Speleology

This is a description of the affinities and biogeographic significance of three new cavernicolous species of Diplopoda from France and Morocco. One species apparently belongs to the Polydesmida (family Paradoxosomidae) and the other two to Craspedosomida (families Caratosphydae and Chordeumidae).

1) Eviulisoma abadi n.sp. is distinguished from other species of this genus by total depigmentation, by the characters of the gonopodial orifice and the male gonopods, by the low number of segments (19) and by its geographic isolation (Morocco) and ecology (Kef Aziza cave). This justifies the establishment of a new sub-genus, Jeekelosoma. The other species of this genus …

The Anatomy And Histology Of The Alimentary Tract Of The Blind Catfish Horaglanis Krishnai Menon, T. V. Anna Mercy, N. Krishna Pillai

International Journal of Speleology

H. krishnai is a blind catfish inhabiting the dug-out wells at Kottavam Kerala, South India. Studies on the alimentary tract of the fish show that, the alimentary tract, though typically teleostean, shows several adaptive modifications. The bulbous stomach helps in storing food which is helpful in an environment chronically deficient in food. The ileo-rectal sphincter helps in retaining the digested food in the intestine for a long duration to facilitate maximum absorption. This is very helpful as the intestine is short. The liver is well developed.

Nouvelles Données Morphologiques Et Caryologie Du Triclade Hypogé Pyrénéen Dendrocoelum Lescherae, Nicole Gourbault

International Journal of Speleology

The study of a new strain of the hypogeous Tricladida Dendrocoelum lescherae has demonstrated the very low anatomical variability of this species. The chromosome complement was found to be 2n = 32; measurements of somatic mitoses have shown that these elements are metacentric; the gametocytes possess 16 bivalents. Number and morphology of the chromosomes are similar within the subgenus Dendrocoelides.

Two New Genera Of Cave-Dwelling Millipedes (Diplopoda), With Remarks On The Millipede Fauna Of West Caucasian Caves, Sergei I. Golovatch

International Journal of Speleology

Two new genera and species of the Diplopoda from Caucasian caves are described: troglobitic Caucasodesmus inexpectatus n.g., n.sp. (family Macrosternodesmidae) from a cave in North Osetia, North Caucasus, and troglophilic Ratcheuma excorne n.g., n.sp. (family Antroleucosomatidae) from a cave in Racha, Georgia, Transcaucasia. Millipedes of the western Caucasian cavernicolous fauna are reviewed as regards their distribution, relationship with caves and zoogeographical connections.

Morphological Clines In Reduced Areas. The Case Of Henrotius Jordai (Reitter), Cave-Dwelling Beetle From Majorca Island, Xavier Bellés

International Journal of Speleology

The present paper shows a statistically significant correlation between the geographical latitude and the morphological variation of the pronotum of Henrotius jordai (Reitter) (Col. Caraboidea), cave-dwelling beetle from Majorca island, after studying the linear and curvilinear regression between these two variables. The existence of specimens situated at different heights of the regression lines leads to the conclusion that morphological variation is clinal. The phenomenon of “semi-isolation” to which the studied populations are subjected, because of their cavernicolous character, allows to explain the existence of a cline in such a restricted area as that occupied by this beetle (ca. 500 Km …
