• Analysing humpback whale (Megaptera novaeangliae) population dynamics and regional migration patterns of breeding substock C1 using song characteristics

My project involved designing and investigating the population dynamics and migrations of humpback whales at their breeding grounds in Mozambique. The combination of sighting data and vocalisations allows analysis of their population dynamics, such as breeding pairs and sex ratios and comparison of the data collected to previous years to determine if these have changed. Song characteristics are important when considering migration patterns in humpbacks, as the song similarity between other sub-stocks (e.g. C2, Madagascar) can give an indication of interaction e.g. immigration and the pathways they take during their long migrations. The scientific framework surrounding this species in Mozambique is currently under supported, so the data collected will allow me to contribute significantly to ongoing research. Furthermore, with this information, Guinjata Bay has the potential to become a Marine Protected Area, meaning one of the most important humpback breeding grounds in the world will be protected for future generations.
