Ethanol whole plant extracts of three halophytic plants from Bahrain Sesuvium verrucosum, Salsola baryosma, Zygophyllum quatarense have been tested for their cytotoxic activity by the brine shrimp method. Only S. verrucosum showed a marked significant activity (LC50 = 102.7 µg/mL) Copyright © 2000 John Wiley & Sons, Ltd.

Intertidal mudflats in Bahrain provide essential feeding grounds for a good number of shorebirds. The spatial distribution of soft-sediment macrobenthic invertebrate assemblages inhabiting a mudflat designated as a natural marine protected area was investigated to characterize shorebird food supplies. Molluscs accounted for 88% of the total macroinvertebrates community, reflecting a dominance of gastropod grazers. Six species of wading birds were recorded feeding in the protected area. Bird disturbance associated with human recreational activities that may interfere with the conservational benefits of this protected area was explored. This study highlighted the crucial need for management plans for protected areas and for further research concerning bird disturbance.
