Professor Craig Johnson is Head of the Ecology & Biodiversity Centre at the Institute for Marine & Antarctic Studies (IMAS), and Associate Director of IMAS.  He is a marine community ecologist interested in identifying the drivers of marine community dynamics, and how to interpret change in marine communities. He works mostly with shallow reef systems, but current work also includes the Southern Ocean. His work is evenly divided between field programs and computer modelling, and across animals and seaweeds. He leads a productive group of postdoctoral fellows and graduate students.

Biography

Craig completed his PhD in Nova Scotia in Canada in 1985, and he subsequently worked at the Bedford Institute of Oceanography in Canada, Marine Biology Institute at the University of Cape Town, Australian Institute of Marine Science, Griffith University, and in the Department of Zoology at the University of Queensland before moving to take up the Chair in Zoology at the University of Tasmania in 1997.

His research is broadly concerned with the space-time dynamics of marine ecosystems, encompassing interactions among suites of organisms spanning bacteria, algae, invertebrates and fish. img-rMost of his work has focused on temperate and tropical reefs, but is now expanding to include ecological dynamics of the Southern Ocean. A unifying theme of his recent work is to understand change in marine communities, including to discern 'tipping points' in marine systems and identify management options to avoid them. Craig's research activity is divided between field work, which is strongly focused on conducting in situ experiments underwater, and building computer models of marine system dynamics.

Craig chaired the Marine National Facility Steering Committee 2004-14, and maintains a strong interest in ensuring open access to publicly funded scientific data through work on the Steering Committee of the Australian National Data Service. He has played leading roles in a large range of national and international initiatives including establishment and development of the Australian Integrated Marine Observing System (IMOS) and eMII (its data management facility), and the Modeling and Decision Support Working Group of the World Bank Coral Reef Targeted Research Program.

Research Themes

Craig's research is squarely within the Marine, Antarctic and Maritime research theme of the University of Tasmania. Most of his recent and current work is focussed on the ecology of kelp beds, with field work spanning Tasmania, Victoria, New South Wales and Western Australia. However, through collaborative projects he is working on modelling kelp bed dynamics in South Australia and in many other systems worldwide. Most of this work is focused on change in kelp bed systems; in particular, the impacts of climate change and other anthropogenic stressors, the possibility of 'flips' in system state from productive kelp beds to degraded reefs dominated by sea urchin barrens or turfing algae, how to manage kelp-based systems for resilience and maintenance of ecosystem services, and how to restore kelp beds.

A unifying theme in this work is whether temperate reef systems can exist as alternative stable states under identical environmental conditions and, if so, to estimate the size of the hysteresis and implications for management, and to estimate where the 'tipping points' in the system lie. A related current project is assessing whether pelagic Southern Ocean systems to the east of the Kerguelen Plateau can also exist in alternative stable configurations (either dominated by jellyfish and other gelatinous zooplankton, or by krill and other large crustaceans) under identical environmental conditions, and whether this affects foraging patterns in elephant seals.

One particularly exciting project focussed on the effects of climate change on kelp-based systems involves a field experiment of unprecedented scale. The experiment comprises a series of 24 artificial patch reefs set out on a little over a hectare of sea floor, representing 3 groups of 8 reefs of a range of sizes, with each 'group' supporting either zero, modest cover or dense cover of kelps. The experiment is determining how patch size and kelp density affects (1) the kelp's capacity to renew itself, and (2) the make-up of associated seaweeds, invertebrates and fishes.

Other work is concerned with prediction of biodiversity patterns in Antarctic waters, using kelps to mitigate nutrient inputs from finfish aquaculture, and predicting the impacts of climate change on the structure of deep reef (30-100 m depth) communities in eastern Australia.

Using size-based models to understand the role of mesopelagic fish and squid in the Southern Ocean ecosystem (2015 - 2016)$161,325
Description
Mesopelagic fish are the most abundant vertebrate in the biosphere, accounting for more biomass than any other group of fish. In the Southern Ocean, mesopelagic fish and squid play a key role transferring energy from zooplankton to higher predators, and several species of fish are or commercial importance. However, the sensitivity of mesopelagic fish and squid to the combined impacts of fishing and climate change is poorly understood. Model representations of these groups which would inform our understanding of their current status and potential future trends are currently lacking. This project will develop size-based (or size spectrum) models to fill this gap. Size based model provide a powerful means to understand how marine communities are organised and how they respond to fishing and climate change. This project will advance our understanding of the role of mesopelagic species in Southern Ocean ecosystems and inform the development of indicators for ecological change.

Fish and invertebrate recruitment in response to varying kelp habitat population dynamics (2014 - 2015)$14,500
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.

Dynamic resilience and stability properties of marine systems: the importance of environment-engineer feedbacks in kelp forests (2013 - 2015)$325,000
Description
Habitat-forming ecosystem engineers modify the environment to the benefit of many other species, and are crucial to the functioning of their ecosystem. This project proposes that the environmental changes they cause are also crucial to the stability and resilience of the ecosystem engineer species themselves, i.e. that there is a positive feedback between changes to the environment caused by the engineer species and the engineers demography (an environment-engineer feedback). The project will test this idea for the most ecologically important habitat-forming kelp (Ecklonia radiata) in temperate Australasia, generating new knowledge to identify critical thresholds for this key habitat-forming species in the face of significant anthropogenic threat.

Effects of Climate Change on Temperate Benthic Assemblages on the Continental Shelf in Eastern Australia (2011 - 2014)$556,800
Description
Change in behaviour of the East Australian Current (EAC) underpins a rate of ocean warming in SE Australia 3.8 times the global average and declining nutrient levels. The proposed work will determine present patterns of physical parameters on the continental shelf in SE Australia, and predict changes in both the trend and variability of the temperature and nutrient signal on the shelf. These data will be combined with observations of benthic communities 0-200 m depth to, for the first time, develop bioclimate models to predict changes in these key habitats so important for major fisheries and as areas of high biodiversity. Unique data from experiments will enable testing the efficacy of current approaches to bioclimate prediction.

Impacts of Climate Change on Key Habitat-forming Seaweeds in SE Australia (2010 - 2012)$275,000
Description
This projects addresses effects of climate change on three key habitat-forming seaweeds on rocky reefs in SE Australia in a region currently warming at around 3.8 times the global average. Importantly, it examines the synergistic effects of changes in both temperature and nutrient levels, since the two are tightly linked in Nature. The project assesses whether performance of individuals within warmer parts of species' ranges is helpful in predicting responses to climate change in colder parts of a range and, in one key species (Ecklonia radiata), estimating the heritability of key traits and thus the potential to adapt to climate change.
