الملخص

Observing populations at different spatial scales gives greater insight into thespecific processes driving genetic differentiation and population structure. Here wedetermined population connectivity across multiple spatial scales in the Red Sea todetermine the population structures of two reef building corals Stylophora pistillata andPocillopora verrucosa. The Red sea is a 2,250 km long body of water with extremelyvariable latitudinal environmental gradients. Mitochondrial and microsatellite markerswere used to determine distinct lineages and to look for genetic differentiation amongsampling sites. No distinctive population structure across the latitudinal gradient wasdiscovered within this study suggesting a phenotypic plasticity of both these species tovarious environments. Stylophora pistillata displayed a heterogeneous distribution ofthree distinct genetic populations on both a fine and large scale. Fst, Gst, and Dest were allsignificant (p-value<0.05) and showed moderate genetic differentiation between allsampling sites. However this seems to be byproduct of the heterogeneous distribution, asno distinct genetic population breaks were found. Stylophora pistillata showed greaterpopulation structure on a fine scale suggesting genetic selection based on fine scaleenvironmental variations. However, further environmental and oceanographic data isneeded to make more inferences on this structure at small spatial scales. This studyhighlights the deficits of knowledge of both the Red Sea and coral plasticity in regards tolocal environmental conditions.
