Application of genetic and evolutionary approaches in marine conservation and management (Case study: project)
Journal Title: Scientific Annals of the Danube Delta Institute - Year 2015, Vol 21, Issue
Abstract
Contemporary studies of population structure and genetic diversity increasingly employ new analytical and technical tools that provide high-resolution genetic information. These tools, that include procedures such as polymerase chain reaction amplification (PCR) and automatic DNA sequencing, combine to provide unprecedented power to detect and interpret genetic variation in natural populations. There are numerous advantages to applying molecular tools for studying the structure and dynamics of marine ecosystems, especially for purposes of marine reserve design and sustainable fisheries management. For the latter, results of connectivity studies allow us to predict how populations are likely to respond to varying levels of extraction or protection by explicitly accounting for replenishment of populations through local or distant sources. The geographic scale of genetic structure helps guide decisions on the scale of management schemes. We are able to investigate the spatial genetic structure of certain targeted species (in this case species of fish and invertebrates that are of commercial interest) thanks to advances in molecular approaches - both regarding the development of new technologies as well as their increased availability (molecular techniques are becoming more affordable and available for population level studies that require large numbers of samples). Some of the procedures and tools that will be mentioned here are the following: DNA isolation; PCR amplification; Automatic DNA sequencing; Data (DNA sequence) analysis using various software packages which involved sequence alignment and analysis, phylogenetic reconstructions and population genetics.
