Thermal anomaly is among factors initiating coral bleaching and mortalities and threatening coral reefs worldwide. Therefore, susceptibility of corals to thermal stress is a central concern in reef conservation. In this study, we evaluated underwater temperature during 2012-13 and bleaching status of corals during summer 2012 in Hengam Island located in the eastern Persian Gulf. Hengam coral...

BACKGROUND The scalloped hammerhead shark, Sphyrna lewini, is a large endangered predator with a circumglobal distribution, observed in the open ocean but linked ontogenetically to coastal embayments for parturition and juvenile development. A previous survey of maternal (mtDNA) markers demonstrated strong genetic partitioning overall (global Φ(ST) = 0.749) and significant population separation...
