A Plan Of Study Submitted To The Florida Department Of Environmental Regulation Southwest District, Department Of Sanitary Sewers Bay Study Group

Reports

The proposed study will examine effects of nutrient limitation on phytoplankton growth rates in Tampa Bay. The response of growth rate to changes in nutrient additions will be indicated through changes in algal biomass (chlorophyll-a) and fixation of CO2 (C‑14­ uptake). The selected method is similar to methods currently used by the states of Maryland and Virginia for determination of nutrient limitation in Chesapeake Bay waters (Fisher et al. 1992a and b). The proposed study will, therefore, not only yield valuable information about nutrient limitation in Tampa Bay, but will also allow for comparison of information between Tampa Bay and …

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii

Reports

Hillsborough Bay, the eastern uppermost section of the Tampa Bay system, is surrounded by a large metropolitan complex, supports extensive industrial activity, and serves as a major shipping port of fertilizer products. The Bay was determined to be highly eutrophic during the late 1960s. The City of Tampa's primary sewage treatment plant and runoff from fertilizer industry activities were considered as the major sources of excessive nutrient loading. Loadings form both these sources have been reduced during the last 10 years, which has probably been the leading cause of improved water quality parameters such as water clarity, dissolved oxygen, and …

Morphometric Analysis Of Dolines, A. Bondesan, M. Meneghel, U. Sauro

International Journal of Speleology

The doline is the most specific surface form of karst landscapes, which enables one to distinguish them from “normal” erosion landscapes shaped by surface water. From a morphodynamic point of view the doline constitutes an elementary hydrographic unit, comparable to a simple basin, which, with its system of slopes, conveys water to the absorbing points at the bottom into an underground network. The morphometric study of these karst landforms enables a quantitative analysis of karst environment. Comparisons of the various parameters may give unexpected results and lead to new hypotheses about the evolution and the dynamism of the karst “geo-ecosystem”. …

Speciation Of Troglobites: Studies In The San Antonio Cave (Oaxaca, Mexico), Horst Wilkens, Peter Junge, Thomas G. Langecker

International Journal of Speleology

The phylogenetically young species community of San Antonio Cave (Oaxaca, Mexico) exemplifies the hypothesis that speciation of troglobites can occur in close contact with epigean predecessors. In a subterranean creek which continues outside with a rich epigean fauna, four troglobitic aquatic crustacean and one fish species (Rhamdia reddelli, Pimelodidae) were studied. Today not a single surface specimen can be found in the cave waters although several epigean species are troglophilic and/or are the ancestors of cave forms in other parts of Mexico. The absence of epigean invaders is attributed to the presence of specimens of some of the …

Population Size Of Pyrenean Troglobiont Coleopters (Speonomus Species) In A Cave In Belgium, Raymond Tercafs, Christine Brouwir

Metabolic Efficiency And Regulation Of Body Weight: A Comparison Between Life In Hypogean And Epigean Ecosystems, Jayant Biswas

International Journal of Speleology

In the present study metabolic efficiency in the epigean and hypogean populations of Nemacheilus evezardi (Day) was examined. Different experiments were conducted, in both populations, by keeping them either in restricted oxygen or restricted feeding conditions, including starvation. Results clearly show that the rate of oxygen consumption for the hypogean population was significantly less as compared to its epigean counterpart. Further, results also suggest that the hypogean population has a tremendous capacity to maintain its metabolic activity and regulate its body weight under severe conditions characterized by an absence or a limited supply of food.
