The Molecular Ecology and Fisheries Genetics Laboratory (MEFGL) is a leading research division of the School of Natural Sciences, within the College of Environmental Sciences and Engineering at Bangor University. The MEFGL represents one of Europe’s largest centres focusing on population, species and community diversity of aquatic animals, with additional activities on prokaryotic and eukaryotic groups, including plants, fungi and microbes throughout terrestrial and aerobiological biomes. A central part of our work is the application of molecular markers such as microsatellites, AFLPs, single nucleotide polymorphisms (SNPs) and sequence data (Sanger and Illumina) to fundamental evolutionary and ecological questions relating to the origins, levels, distribution and ecological significance of genetic variation in wild and managed populations. Molecular genetic data are derived from genomic DNA, community DNA and environmentally “free” DNA (eDNA) at the ecosystem level. In addition to the focus on neutral markers, the application of genomics, transcriptomics and Real-Time PCR facilitates the functional analysis of genomes. The MEFGL complements molecular genetic data with detailed ecological, behavioural, physiological and environmental metadata information to facilitate examination of the underlying causes of individual, population or species diversity in time and space.
