  • BIO235 Molecular Ecology

    Molecular ecology is an emerging field that takes advantage of the latest advances in molecular genetics to answer a varied range of theoretical and practical questions in ecology including conservation genetics, behavioural ecology, phylogeography, adaptation, hybridization and speciation. Through a combination of theoretical lectures, laboratory practicals and class discussions we will consider the application of a range of molecular and statistical tools to problems such as species conservation, biological invasions, wildlife forensics or fisheries. Lectures include a basic introduction to the field of Molecular Ecology and its connections to Conservation Biology and Population Genetics. This will be followed by lectures on population diversity focused on: molecular markers and genetic variation in natural populations, phylogeography and barcoding, population structuring and differentiation, mating systems, behavioural ecology and inbreeding. A more applied part of the programme will include lectures on microbial ecology, forensic science and conservation applications. Two practical lectures will cover the use of barcoding for species identification, including DNA extraction, amplification and sequencing (laboratory based) and the identification of there sequences using databases such as Genbank (computer based).
