الملخص

While geographic distance is a variable often used to explain population genetic differentiation, dynamic processes leading to stochastic population structure are more likely driving factors. The following thesis presents the population structure of a common reef sponge, Stylissa carteri, and yields hypotheses on the influence ofenvironmental heterogeneity as a predictor of the observed population structure. Thisproject represents the largest population genetics study thus conducted in the Red Sea andalso includes the first population genetics data gathered for sites off the coast of Sudanand Soccotra. The study herein presented includes both a large scale (36 reef sitescovering over 1000km of coastline) and small-scale (16 transects of 50m each) analysisof gene flow in a benthic dwelling organism. The variable effect of geography andenvironmental conditions on S. carteri population structure is assessed using a seascapegenetics approach. Environmental factors from a nine-year dataset accessed from theNASA Giovanni website including chlorophyll a, sea surface temperature, dissolved andparticulate organic matter for both the annual and winter temporal scale were considered.
