Coral settlement is a key ecological process in the maintenance, recovery and resilience of coral reef ecosystems. Coral reefs in the Persian Gulf survive in one of the world’s most extreme environments, yet there remains limited knowledge of the role of coral settlement considered critical for maintaining population dynamics. Spatial and temporal patterns of coral settlement were examined at 6...

The present study has revealed that, the temperature has a crucial role among the observed physiochemical parameters on the growth and survival of P. margaritifera spat. Instantaneous growth rates (IGRs) in DVM, APM and TWT were calculated and used to assess the variation in growth of spat reared with different feed mixtures (FM-1 8) of five diatoms and stocking densities (SD-10, 20 and 30). Am...

Stable carbon and nitrogen isotope ratios were used to define the trophic base of the infaunal suspension-feeding bivalve Cerastoderma edule (L.) living on an intertidal muddy sandflat in Marennes-Oleron Bay, France. Suspended particulate organic matter (POM) collected from adjacent marine channels had a mean 6I3C value of -22 2 * 1.1 %O (n = 19). Benthic primary producers on Ronceles-Bains tid...

Bivalve metamorphosis is a developmental transition from free-living larva to benthic juvenile (spat), regulated by complex interaction of neurotransmitters and neurohormones such as L-DOPA epinephrine (catecholamine). We recently suggested an N-Methyl-D-aspartate (NMDA) receptor pathway additional previously unknown regulator bivalve metamorphosis. To explore this theory further, we successful...

Traffic intersections throughout the United States combine fixed, semi-actuated, and fully actuated intersections. In case of semi-actuated intersections, uncertainties are considered in phase duration. These due to car waiting queues pedestrian crossing. Intelligent transportation systems deployed traffic infrastructure can communicate Signal Phase Timing messages (SPaT) vehicles approaching c...
