PROJECT

Improving seagrass restoration from the ground up

Determining how seagrass-sediment feedbacks can be harnessed to improve success of seagrass restoration

 

To date, seagrass restoration efforts to promote natural recovery and/or enhance seagrass planting success have tended to focus solely on improving above-ground processes (e.g. light availability, water quality and hydrodynamic turbulence). However, below-ground processes under microbial control (i.e. plant-sediment feedbacks), a known regulator of plant performance, is also critical for enhancing restoration of seagrasses. Below-ground processes have the potential to benefit seagrass growth and survivorship via increasing availability of plant nutrients, creating suitable environmental conditions (e.g. buffering sediment pH and redox potential), or by pathogen defence and production of plant hormones.

This project will involve a combination of tank trials (using the newly constructed Waterman’s facility) as well as in-situ restoration field trials to explore if the below-ground environment can be manipulated to improve seagrass restoration. This project is nested inside a larger Nation wide (NSW, Vic, WA and Tas) and international (Singapore) ARC-Linkage project, with significant collaboration between multiple state-NRMs and universities.

 

Project goals:

  • Understand the effects of seagrass-sediment feedbacks on seagrass health.
  • Develop innovative approaches to seagrass restoration

As part of this project the successful PhD applicant will undertake:

  • Tank trials: develop, plan and undertake tank trials that explore the impact of seagrass-sediment feedbacks under different environmental conditions.
  • Field methods: develop, plan and undertake field trials that test seagrass-sediment feedbacks in a field setting.
  • Carry out a mixture of techniques in seagrass and microbial ecology. The techniques the applicant will use will largely depend on the scientific questions of most interest to the applicant, but may include methods such as stable isotope techniques, metagenomics or microscopy.

Research team leader: Dr Belinda Martin

I am a microbial ecologist whose primary research focusses on plant health and microbial functions in ecosystems. My research focusses especially in the rhizosphere environment, which is the zone of soil that is influenced by plant roots. Locally, I work closely with natural resource managers to improve our ability to respond to and manage activities that impact seagrass ecosystems. Internationally, I work with leaders in microbiome research; building capacity and drawing investment into WA in this growing field of microbiome research.  I am also co-director of a science illustration company, Ooid Scientific, specialising in scientific conceptual diagrams and figures for publication.
