Ascidian Investigations In Hillsborough Bay, City Of Tampa Bay Study Group

Reports

The City of Tampa Bay Study Group has noticed high numbers of an anural solitary mogulid tunicate, of an unknown ascidian species, dominating some bottom communities of Hillsborough Bay during the winter. Ascidian concentrations have been found in excess of 4000/me , and lengths have ranged from O.25mm to 20mm for larvae and adults, respectively. Coincident with these high ascidian concentrations, excellent water clarity has been observed, where the bay bottom is visible through water of 2 to 3m depths. Ascidians can filter large volumes of seawater as part of their food gathering process. Although not found in Hillsborough Bay, …

Caratteri Generali Delle Morfologie Nelle Alpi E Prealpi Giulie E Nel Carso Triestino, Franco Vaia

International Journal of Speleology

The morphology of the Julian Alps and Prealps and of the Triestian Karst are here shortly described; the structures, which defined its origin and development, are also considered. We can notice some cliffs which follow one another from the State boundary to the Adriatic sea; they are made up by lithologic successions, which repeat themselves according to the latitude. Anyway we recognize a general outcropping of rock masses which are decreasing little by little southward as regards the altitude, the age and than the erodibility. There are some differences between the western (Carnian) and the eastern (Julian) bend of the …

Variation In Sulfur Dioxide Emissions Related To Earth Tides, Halemaumau Crater, Kilauea Volcano, Hawaii, Charles B. Connor, Richard E. Stoiber, Lawrence L. Malinconico Jr.

School of Geosciences Faculty and Staff Publications

Variation in SO₂ emissions from Halemaumau crater, Kilauea volcano, Hawaii is analyzed using a set of techniques known as exploratory data analysis. SO₂ flux was monitored using a correlation spectrometer. A total of 302 measurements were made on 73 days over a 90‐day period. The mean flux was 171 t/d with a standard deviation of 52 t/d. A significant increase in flux occurs during increased seismic activity beneath the caldera. SO₂ flux prior to the this change varies in a systematic way and may be related to variation in the tidal modulation envelope.

Such information is much needed in order to make sound decisions concerning seagrass restoration and viable mitigation options.

Effect Of Wet Tropospheric Path Delays On Estimation Of Geodetic Baselines In The Gulf Of California Using The Global Positioning System, David M. Tralli, Timothy H. Dixon, Scott A. Stephens

School of Geosciences Faculty and Staff Publications

Geodetic baseline measurements using the Global Positioning System (GPS) were acquired in the Gulf of California between Loreto and Cabo San Lucas in Baja California and Mazatlan on the mainland of Mexico. Tropospheric water vapor content was high during the experiment, typically yielding wet path delays in excess of 20 cm at zenith. Surface meteorological (SM) and water vapor radiometer (WVR) measurements were recorded at each site, providing independent means of calibrating the GPS signal for the wet tropospheric path delay. Residual wet delays at zenith are estimated as constants and also as first-order exponentially correlated stochastic processes. In addition, …

Water Quality 1986 - 1987 Hillsborough County, Florida, Hillsborough County Environmental Protection Commission

Reports

The Hillsborough County Environmental Protection Act charges the Environmental Protection commission with the function of establishing, operating and maintaining a continuous program for monitoring water pollution. A county-wide water quality surveillance network has been designed to enable the staff to determine compliance with the Act and to determine whether the level of water pollution is increasing or decreasing throughout the county.

These data, obtained during 1972-1987 may provide useful background for eventual development, revision _ and enforcement of regulations, standard effluent limitation plans, or programs established under the Federal Water Pollution Control Act of 1972.

Mating Behaviour And Barriers To Hybridization In The Cave Beetle Of The Speonomus Delarouzeei Complex (Coleoptera, Catopidae, Bathysciinae), Lysiane Juberthie-Jupeau

International Journal of Speleology

The complex Speonomus delarouzeei combines 6 species which were previously synonymized. Using behavioural data, based on 12 populations, the author assesses the validity of 4 species and points out the occurrence of 2 species as yet undescribed. Constant and important differences during the mating appear between these different species. They concern the number of behavioural steps, the duration, the number of clappings of antennae, the abdominal male movements and the rubbing of female abdomen. The results of crossing experiments between different species indicate a prezygotic reproductive isolation with atypical matings and no sperm deposit. Between the populations of S. delarouzeei …

Evolutionary Genetics And Morphometrics Of A Cave Crayfish Population From Chiapas (Mexico), Valerio Sbordoni, Giuliana Allegrucci, Fabiola Baldari, Donatella Cesaroni

International Journal of Speleology

The recently explored Cueva de Los Camarones, in the remote village of Constitucion, Chiapas, Mexico, houses a unique highly variable population of Procambarus crayfish (Crustacea, Decapoda). Morphologically, a more or less clinal variation is revealed at several features such as the degree of rudimentation in both pigmentation and eye, and the elongation of body and appendages. Extremes are quite different, ranging from typical dark, thick, eyed individuals to light, elongated, microphtalmic phenotypes. Evolutionary relationships among individuals were investigated electrophoretically (25 structural gene loci) and morphometrically (12 characters) by means of multivariate analyses. Results from analysis of individual allozymic multilocus profiles …

Paleoenvironment And Speciation In The Cave Beetle Complex Speonomus Delarouzeei (Coleoptera, Bathysciinae), Christian Juberthie

International Journal of Speleology

In the eastern part of the Pyrenees (France) the author describes a scenario of speciation in the cave species complex Speonomus delarouzeei (Coleoptera Bathysciinae); the speciation processes have been initiated by a breakdown of the ecological equilibrium induced during three glacial-interglacial episodes. The scenario is the following: — during the first glaciation (2.3-2.1 MY), psychrophilic populations ancestral to S. brucki were selected over the highest elevation of the range, by means of cold effect which produced an adaptive demographic advantage; adaptive characters of troglobitic species (K strategy) take place presumably in relation to colonization of caves and M.S.S.; — during …

A Few Parts In 108 Geodetic Baseline Repeatability In The Gulf Of California Using The Global Positioning System, David M. Tralli, Timothy H. Dixon

School of Geosciences Faculty and Staff Publications

Global Positioning System (GPS) geodetic measurements of 350–650 km baselines across the Pacific-North America plate boundary in the Gulf of California are presented. The analysis employs a four-station U.S. fiducial network and combined carrier phase and pseudorange data. Water vapor radiometer (WVR) data at the Gulf sites are used to calibrate the GPS signal for wet tropospheric path delays. Residual tropospheric delays are modeled as first-order exponentially correlated stochastic processes. The measurement precision for horizontal components is a few parts in 10⁸ or better. Comparison of the Gulf data with other geodetic techniques is not yet possible, however the …

Pseudosinella Revisited (Collembola, Entomobryinae), Kenneth Christiansen

International Journal of Speleology

Eight controversies are active in the study of macroevolution. These are: 1) the meaning of the term macroevolution, 2) the role of chance, 3) the role of stasis and gradualism, 4) whether significant change is Iimited to speciation events, 5) the environmental conditions where macroevolutionary change occurs, 6) whether Neodarwinian mechanisms are adequate to explain change, 7) the existence and nature of hierarchical evolutìonary processes, and 8) Darwin’s views about all this. After a brief examination of each of these issues we used the extensive data available for 9 species of European and Nearctic cave Pseudosinella to examine the third, …

Eruptions Of Pavlof Volcano And Their Possible Modulation By Ocean Load And Tectonic Stresses, Stephen R. Mcnutt, R. J. Beavan

School of Geosciences Faculty and Staff Publications

All nine magmatic eruptions at Pavlof Volcano in six of the years from 1973 to 1984 have occurred between September 9 and November 20. Volumes of erupted material range from 0.1 to 15.9 × 10⁶ m³ (dense rock equivalent) at an average rate of ∼3 × 10⁶ m³ yr⁻¹. The volumes are estimated from eyewitness reports for two eruptions; the others are estimated from a relationship that we derive between eruption volume and harmonic tremor duration and amplitude. The volume of lava erupted is approximately time predictable. A significant correlation exists between the eruptions …
