Overview of thesis

My research will focus on the resilience of seagrass populations within North West Australia particular to the distribution and reproduction of species found in this region. The study will investigate seagrass reproduction with an emphasis on the conditions required for seed production, sexual reproduction, and to achieve maximum germination. This will be achieved through survey data on the distribution of seagrass species in the region, and examination of the reproductive effort and seed banks at a variety of sites. As species vary in their reproductive methods the data collected will increase our knowledge of the biology of each species offering a more in-depth understanding of these important ecosystems with a focus on the seagrass species Halophila ovalis. I will also be evaluating the population densities in each area using both the leaf and shoot measurements as larger scale biomass indicators which will also help to determine species diversity in the region.
