Changes in functional diversity of reef fishes within an ocean warming hotspot: implications for temperate reef resilience (PhD)
Globally, the many marine taxa are shifting their distribution in response to ocean warming to track their climatic niche. Species re-distributions might have profound implications on ecosystem functioning and services as they not only modify the taxonomic makeup of a community (i.e. species composition and diversity) but ultimately also modify the range of functions (i.e. measured in terms of functional traits) of the resident community, with drastic and unknown consequences for ecosystem dynamics. The main goal of my PhD is to understand how the geographic shift of tropical fishes is altering the functional diversity of temperate reefs fish communities and its ecological, social and economic implications. Specifically, I will use long-term continental scale data sets, and field surveys to investigate:
i). Australia-wide patterns in functional diversity of reef fishes.
ii). How warming interact with latitude to reshape these patterns.
iii). The effects of methodological biases in the spatio-temporal assessment of functional diversity.
iv). The extent to which a particular tropical species (the blue-barred parrotfish, Scarus ghobban) can maintain its ecological role in novel ‘tropicalised’ reefs.
