The book "Marine Genetics" provides a comprehensive overview of the advances in the molecular population genetics of marine organisms. Over the past two decades, our knowledge of the ecology, distribution, and evolution of these organisms has significantly expanded through the use of modern genetic analysis tools. The content is based on the insights of leading experts who gathered in Rio de Janeiro to discuss the current state of research. Topics covered include the molecular analysis of bioinvasions, developments in marine biotechnology, as well as genetic variations and the population structure of marine organisms. These findings are of great importance for the fields of conservation biology, fisheries, and aquaculture. The book is aimed at biology students, researchers, and anyone interested in marine biology, zoology, ecology, as well as population and molecular genetics.
