Changes in temperate seaweed communities and the associated subtidal reef ecosystem (PhD 2021)
Temperate subtidal reefs are home to one of the most productive ecosystems in the world. As foundation species, habitat forming seaweeds provide the three-dimensional structure and primary productivity that supports diverse communities of associated fauna. As anthropogenic climate change continues to affect ecosystems around the world, temperate ecosystems are amongst those heavily impacted. In my PhD I look at some of the changes in seaweed and associated fauna over the past decades in Western Australia; a global warming hotspot. Furthermore, I investigate the dissolved organic matter (DOM) that healthy seaweeds exude into the ecosystem, comparing the quantity and quality of DOM that historically dominant Ecklonia radiata exudes versus that which Sargassum spp. and Lobophora variegata – two species increasing in abundance – exude. In doing so I aim to better understand at the link between primary and secondary producers within the ecosystem, in order to better understand the effect that changes in seaweed communities have on the ecosystem they support.
