“Access to data in AEKOS saved me heaps of effort”  - Dr Greg Guerin

“I’ve used data in ÆKOS to derive new subset of data to study a number of macroecology topics mainly because the ÆKOS Data portal and the user support helps me to be efficient and publish my work earlier than planned.”

Greg downloaded 330,004 records of 3,083 vascular plant species in 14,328 plots of the Biological Survey of South Australia from the ÆKOS Data Portal to developed a new geo-referenced measure of endemism based on ‘span’ and ‘area’ called extent of occurrence. Greg and his colleagues published this alternative implementation of inverse range weighting.

‘I also archived the study’s derived dataset that was subsetted from ÆKOS in ÆKOS with a DOI using the SHaRED data submission for reasons of research transparency’, says Greg.

In another study that identified regional centres of plant biodiversity, Greg and colleagues compiled 727,417 plant species records from plot-based field surveys from ÆKOS and herbarium records and mapped a number of compositional attributes of South Australian species diversity and threatening processes at local and statewide scales. A new TERN AusPlots dataset was subsetted from and archived in ÆKOS with the scientific paper. The work identified six centres of high plant biodiversity in South Australia and some quirks in the datasets.

‘Interestingly, biodiversity scores were not always congruent between metrics or datasets and herbarium species occurrence data (sometimes referred to as biodiversity data) were more biased towards major transport corridors’, he said.

The public’s interest in Greg’s work arising from TERN’s data infrastructure investment and other infrostructure have been reported by the ABC News.

Greg’s research interests within Professor Andrew Lowe's group and TERN’s AusPlots and Australian Transect Network involves two main themes. First one is the ecological analysis of ecological communities along large-scale monitoring transects, particularly the TREND transect and the other is continental scale analysis of the distribution of plant biodiversity at ecosystem level.
