Cayne.Layton@utas.edu.au

Cayne Layton is a Postdoctoral Research Fellow & Lecturer at the Institute for Marine and Antarctic Studies. He studies the ecology and restoration of kelp forests and temperate reef systems. Cayne combines field and lab experiments, and scientific diving to examine how kelp forest ecosystems function and persist, especially in the face of increasing anthropogenic stressors. He seeks to answer fundamental ecological questions while ensuring his research has practical applications for habitat conservation, restoration, and management. Cayne is also an active science communicator and has a keen interest in scientific/research diving, and the engagement of science with education and policy.

Biography

Cayne completed his PhD at the Institute for Marine and Antarctic Studies, researching the population and community ecology of Ecklonia radiata kelp forests. This project centered around several long-term field experiments and involved over 400 hours of diving. Cayne’s passion for temperate reef ecology and scientific diving brought him to the University of Tasmania from the Australian National University, where he completed his bachelor’s degree in science with honours (majoring in Zoology and Ecology & Evolution) and worked as a research assistant.

Cayne’s research actively engages with a variety of partners, including NGOs, Aboriginal organisations, industry, and government. He is a member of the NESP Marine Biodiversity Hub, and the Hidden Deserts, Marine Forests, and OzFish citizen science initiatives

Research Themes

Cayne’s research aligns with the University’s research themes of ‘Marine, Antarctic and Maritime’ and ‘Environment, Resources and Sustainability’. His research focusses on how temperate marine ecosystems (especially kelp forests) function, and how they respond to climate change and other anthropogenic stressors. His broader research interests include facilitation and niche theories, and habitat stability and resilience. Cayne also utilises physiology and genetics research to improve understanding of ecological outcomes and mechanisms. His work also focusses on restoration of kelp forest ecosystems, and kelp aquaculture and Integrated Multi-Trophic Aquaculture.

Collaboration

Cayne is currently involved in collaborations with researchers in Chile, New Zealand, Spain and the USA. Domestically, Cayne has collaborators at Deakin University, Melbourne University, Southern Cross University, University of Western Australia and UNSW.

Projects

TNC Kelp Conservation Project (2021 - 2022)$114,450
Description
IMAS-UTAS & TNC have forged a partnership to research and better understand the decline and restoration of giant kelp(Macrocystis pyrifera) in Tasmania. Some of the work is a continuation and extension of previously funded projects at IMAS (e.g. giant kelp breedingand outplanting), whilst novel elements include predictive modelling and quantitative assessment of giant kelp distribution in Tasmania, along withcoordination between project workers and TNC partners on the production of a global kelp restoration guidebook.

NRM South Giant kelp biodiversity (2020 - 2022)$40,000
Description
Dense giant kelp (Macrocystis pyrifera) forests were previously a conspicuous and iconic feature of the Tasmanian coast, but loss of ~95% of these giant kelp forests over the past several decades has seen them listed by the Australian Government as an endangered marine community. Active restoration of these degraded and disappearing habitats represents a potential approach for conservation of giant kelp forests. This project will leverage from the larger IMAS Giant Kelp restoration project, and specifically, will monitor and examine the reestablishment of biodiversity within the restored patches of giant kelp. The project will also provide training support to community groups and/or seafood industry stakeholders in kelp cultivation, and technical advice for development of school and community educational resources regarding giant kelp restoration.

Palawa Shell Necklace Practice and Ocean Change: Climate Change and Aboriginal Culture (2020)$15,225
Description
The health and wellbeing of the Lutruwita Aboriginal community are connected to practice of making necklaces from maireener shells, and although the end product is beautiful and has been displayed in art galleries globally, to the Lutruwita Aboriginal women who uphold this practice the most important thing is the process they take to get there. Over the last decade Elders have noticed a change in abundance and shell thickness of the maireener shells changes that are consistent with scientists expectations under climate change. We propose oral histories be recorded to robustly document the important shifts observed in these culturally valuable species. There is little mention of these species in any other studies (Indigenous or western science) despite their immense value to the community. We propose the collection and analysis of oral histories to develop baseline data on this culturally critical species, to 1) help establish any contemporary climate change impacts, 2) indicate any required future scientific studies, and 3) provide the basis for developing future adaptation options.

Restoration and permaculture of giant kelp forests in Tasmania (2018 - 2019)$235,537
Description
Giant kelp (Macrocystis pyrifera) forests were previously a conspicuous and iconic feature of the eastern Tasmanian coast, but loss of ~95% of dense surface canopies has seen giant kelp forests listed as an endangered marine community in Australia. The collapse of giant forests is associated with ocean warming and the increased influence of warm East Australian Current water in eastern Tasmania. Nonetheless scattered healthy individual giant kelps persist. This project is focussed on identifying warm tolerant genotypes, and means to restore dense surface canopy stands of giant kelp that are self-replenishing and self-expanding. This research will also aid development of giant kelp for commercial harvest and as a means to ameliorate nitrogen input from fish farms in an integrated multi-trophic aquaculture setting.

Fish and invertebrate recruitment in response to varying kelp habitat population dynamics (2014 - 2016)$22,000
Description
The project aims to achieve a broader understanding of how aspects of kelp population dynamics (density and habitat patch size) may influence the recruitment of associated invertebrate and fish species. This information will help to fill a gap in existing knowledge of the links between kelp community health and the biodiversity and productivity of kelp reef habitats as a whole.
