ABSTRACT
An expansion is underway of a nuclear power plant on the shoreline of Biscayne Bay, Florida, USA. While the precise effects of its construction and operation are unknown, impacts on surrounding marine habitats and biota are considered by experts to be likely. The objective of the present study was to determine the adequacy of an ongoing monitoring survey of fish communities associated with mangrove habitats directly adjacent to the power plant to detect fish community changes, should they occur, at three spatial scales. Using seasonally resolved data recorded during 532 fish surveys over an 8-year period, power analyses were performed for four mangrove fish metrics (fish diversity, fish density, and the occurrence of two ecologically important fish species: gray snapper (Lutjanus griseus) and goldspotted killifish (Floridichthys carpio). Results indicated that the monitoring program at current sampling intensity allows for detection of <33% changes in fish density and diversity metrics in both the wet and the dry season in the two larger study areas. Sampling effort was found to be insufficient in either season to detect changes at this level (<33%) in species-specific occurrence metrics for the two fish species examined. The option of supplementing ongoing, biological monitoring programs for improved, focused change detection deserves consideration from both ecological and cost-benefit perspectives.

Synchronous multiple primary malignant neoplasms of different tissues or organs are being documented with increasing frequency. Awareness among clinicians is essential to the evaluation and follow-up of these patients. A rare case of the simultaneous occurrence of vulvar, breast and colon carcinoma underlines this fact.

A detailed description of the clinical and morphological aspects of a case of carcinoma of the cervix arising from mesonephric duct remnants is presented, and the literature pertaining to these rare tumors is discussed. At the time of initial surgical treatment the tumor was confined to the cervix; however, eventual metastatic dissemination to the bony and soft tissues of the pelvis, the lungs, and the lower vertebral column resulted in the patient's death 8 years later. The tumor appeared refractory to further attempts at treatment with radiation, progestational therapy, and variety of chemotherapeutic agents. The observation of a focal cylindromatous growth pattern, not previously described in tumors of this type, is presented.
