Environmental stress and species interactions (PhD 2015)


My thesis looked at the role that ecological processes such as herbivory, competition and facilitation play in structuring seaweed canopies. I was particularly interested in how these relationships responded to environmental gradients and how these interactions affect community structure and ecosystem function. My research investigated the capacity of canopy forming seaweeds to withstand increasing ocean temperatures and whether changes in canopy structure (i.e species composition) among different climates, alters the function of the canopy within reef ecosystems.

I addressed these questions by using a macro-ecological and comparative experimental approach, looking at seaweed growth and community interactions along a latitudinal gradient from the south west coast of Australia (34oS) to Ningaloo Reef (21oS).

Spanish-Australian fusion (aka paella on the barbie): Scott and Juls follow through on the proud tradition of WernbergLab cultural appreciation cooking sessions. Not shown: an amazing tapas of Spanish omelette, ham, octopus, olives and sausage. Great way to finish the City to Surf – well done to all lab runners, walkers, stalkers and water boys!

Scott delivering his valedictory address: “Life is a journey of learning, knowing how to learn and to think broadly is most important. UWA and working in the world’s best natural laboratory – The Great Southern Reef – has provided this skill”. Good on ya’ for getting the GSR in there Scotty!
