In this thesis, genetic differentiation processes on different levels were studied in the anemonefish genus Amphiprion. The studied species inhabit the Indo-Malay Archipelago, located between the Pacific and Indian Ocean comprising the world's richest marine shallow water biodiversity. Differentiation processes on species and intra-specific levels were revealed by phylogenetic and population genetic analyses, based on mitochondrial DNA sequences and microsatellites. Phylogenetic analysis uncovered cryptic diversity within the genus Amphiprion that should be considered when assessing biodiversity of the region and the classification of conservation units. Population genetic analyses showed strong population structuring within the species A. ocellaris, influenced by the oceanographic complexity and dynamic geological history of the area. Information about connectivity patterns among populations of commercially caught coral reef organisms like A. ocellaris can be useful for effective conservation efforts and the sustainable use of marine resources.
