Jason Tanner

Biosecurity Working Group Leader

 

Jason Tanner

 

Areas of expertise:

Benthic ecology, Seagrass epifauna interactions, Population and community modelling, Landscape ecology, Environmental assessment.

Countries of work experience:

Australia, Jamaica, USA.

 

Experience and qualifications:

Dr Tanner has 17 years experience in marine ecology, working in both tropical and temperate systems. He has published 30 papers, most in high profile international journals.

 

In the last 7 years, he has played a key role in the development of the Marine Environment & Ecology Program, which he leads, as well as the Inland Waters and Oceanography programs. ME&E conducts research into environmental assessment of human activities in marine ecosystems, including aquaculture, pollution, dredging etc; the effects of marine invasive pests; and large marine predators. He has been heavily involved in several major projects in this time, include a large multidisciplinary study of the state’s coastal waters to identify and assess areas potentially suitable for the development of aquaculture. Other large projects include the environmental assessment of proposed dredging operations at Outer Harbour, and the assessment of the fate of wastes from aquaculture operations. He has run a number of projects to examine environmental effects of aquaculture and to develop models of finfish carrying capacity. In addition, he heads a major collaborative project to develop an integrated hydrodynamic, biogeochemical and sediment model of the Port Lincoln tuna farming area, and is habitat theme leader for the CLLAMM Ecology cluster, overseeing the development of a dynamic habitat model of the Coorong.

 

Prior to that, he spent 3 years working with SARDI examining habitat change in Gulf St Vincent. This focussed predominantly on the consequences of seagrass fragmentation for associated fauna, and working with the prawn industry to examine the impacts of commercial trawling on benthic fauna.

 

Another component of this work was the assessment of habitat distributions over large scales using remote video cameras. He has also done some work on the ecology of introduced marine species, to develop an understanding of the potential impacts these species may have on our ecosystems.

 

Prior to moving to SARDI, he spent 8 years researching the population and community ecology of benthic invertebrates on coral reefs, involving extensive field surveys and experimental work, as well as mathematical modelling. This is continuing, with the current focus being long–term (40 years) dynamics of corals.

 

Dr Tanner has also maintained close involvement with several universities, and participates in undergraduate and graduate teaching. At the undergraduate level, he has contributed to courses on coral reef ecology, marine ecology, biometrics and population modelling, while at the graduate level he has supervised 10 honours and 4 PhD students.
