Heatwaves, herbivores and the future of the Great Southern Reef

Thomas Wernberg UWA Oceans Institute & School of Biological Sciences, Indian Ocean Marine Research Centre M470, The University of Western Australia. Norwegian Institute of Marine Research, Nye Flødevigveien 20, 4817, His, Norway. thomas.wernberg@uwa.edu.au The Great Southern Reef (GSR) is an interconnected ecosystem of rocky reefs dominated by kelp forests (Ecklonia radiata). Stretching across the southern […]

Kelp beds as refugia from ocean acidification?

Catriona L. Hurd Institute of Marine and Antarctic Studies, University of Tasmania, Hobart, Australia. catriona.hurd@utas.edu.au Since ~1750, the world’s oceans have absorbed 40% of the CO2 released by human industrial activities, resulting in ongoing alterations to the seawater carbonate system:  in surface waters, levels of dissolved CO2 and H+ are predicted to increase by ~150% […]

The restoration of Australia’s kelp forests, with a focus on Tasmania’s disappearing giant kelp (Macrocystis pyrifera) in a changing climate

Cayne Layton Institute for Marine and Antarctic Studies, University of Tasmania, Hobart, Australia. cayne.layton@utas.edu.au Kelp forests are the foundation of the Great Southern Reef, Australia’s continent-wide temperate reef system that supports high levels of biodiversity, endemism, and economic value. Unfortunately, in Australia and elsewhere kelp forests are declining due to climate change, overgrazing from herbivores, […]

Restoring coastal ecosystems in a time of change

Christopher Hepburn Department of Marine Science, University of Otago, Dunedin, New Zealand hepburnc@planta.otago.ac.nz For the last the last 15 years, I has led transformative climate change, aquaculture and fisheries research and teaching programmes in partnership with coastal communities.  Key to this work is building capacity and applying fit-for-purpose research to empower decision-makers to alter public […]

Global change in seasonally dynamic subpolar kelp forest ecosystems

Kristy Kroeker Ecology & Evolutionary Biology Department Institute of Marine Science, The University of California, Santa Cruz, US. kkroeker@ucsc.edu Consumer-resource interactions structure food webs and govern ecosystem stability, yet our understanding of how these important interactions will change in future CO2 scenarios is hampered by the complexity of direct and indirect effects of multiple stressors […]

Future proofing kelp forests

Melinda Coleman Department of Primary Industries, Fisheries National Marine Science Centre, New South Wales, Australia. melinda.coleman@dpi.nsw.gov.au Climate change is causing widespread habitat deterioration and destruction and presents one of the biggest threats to species and global ecological function. Underwater kelp forests underpin fisheries and vast economic values on temperate coasts but are declining due to […]

Fluctuations in primary productivity and their correlates in the northeast Pacific Ocean

Catherine Pfister Department of Ecology & Evolution, University of Chicago. https://pfisterlab.uchicago.edu/ cpfister@uchicago.edu Spatial and temporal variability in the dynamics of seaweed species are critically important to coastal primary productivity. My research in the northeast Pacific Ocean has attempted to understand the sources of variability and its consequences. The Washington state shoreline represents a spatial gradient […]

Eco-physiological responses of different life stages of kelps to climate change

Pamela A. Fernández Centro i~mar & CeBiB, Universidad de Los Lagos, Puerto Montt, Chile pamela.fernandez@ulagos.cl Anthropogenic climate changes such as ocean warming (OW) and ocean acidification (OA) are affecting the biodiversity and richness of marine ecosystems, leading to e.g., shifts in species geographical distribution across the globe. Kelp forests represent one of the most diverse […]

Importance of kelp population strategies: annual vs. perennial Macrocystis pyrifera population dynamics under a changing environmental scenario

Alejandro H. Buschmann Centro i~mar & CeBiB, Universidad de Los Lagos, Puerto Montt, Chile abuschma@ulagos.cl This presentation summarizes our work over the past two decades with the giant kelp Macrocystis pyrifera trying to understand how annual populations of this kelp species can couple alternate and time separated sporophytic cohorts. The relevance of the development of […]
