Reproductive seasonality and early life temperature sensitivity of the seaweed Scytothalia dorycarpa (Phaeophyceae, Fucales)
My Honours research focused on the endemic habitat forming seaweed Scytothalia dorycarpa which retracted over 100 km from its northern distributional limits following a recent marine heat wave in the waters off south-western Australia.
Through field and laboratory experiments, I characterised the reproductive timing of adults, explored the thermal sensitivity of sensitive microscopic early post settlement stages and quantified recruitment densities along the unique latitudinal temperature gradient of the Western Australian coastline. Results from my research confirmed suggestions that the early life history stages of this seaweed were particularly sensitive to temperature and the species may act as a valuable indicator for climate related ecosystem stress in temperate Australian waters. You can read the abstract for my Honours thesis here [pdf].
