Seaweeds and blue carbon ecology (Postdoc)
Temperate reef ecosystems around the world are under intense pressure from human-caused climate change. This poses a direct threat to the abundant biodiversity these ecosystems support, as well as to the numerous services they provide to millions of people. If kelp ecosystems are to survive climate change, we must find ways of preventing further declines. With that in mind, my PhD endeavors to i) explore novel approaches to increase their resilience to future stress and ii) improve our understanding of the mechanisms hindering their recovery once they have collapsed. Efforts to conserve kelp ecosystems will be futile if they lack the appreciation of the public. As such, I intend to step outside the traditional boundaries of ecological research and gain insights from social and economic science.
