Our new review is out in Earth-Science Reviews!
Here, we look at how salinity influences microbial ecology and inhibits healthy nutrient & carbon cycling in these important ecosystems.

Our new study on drivers of methane flux in Lake Qiandao, China - available now in Environmental Science and Technology, @acs.org :
doi.org/10.1021/acs....
Byproducts of degraded terrestrial organic matter drive methane fluxes from this mega reservoir.
Integrated 'multi-omic' evidence like this gives further support for recommendations to improve freshwater flushing of the Coorong to drive the improvement of nutrient pollution (alongside reducing salinity)

These flows drove succession of microbes toward "healthier" nutrient, carbon and nitrogen cycling in the system.
We also found evidence of many (potentially toxic) compounds, including nylon polymers and carbamates. This warrants a further look in.

We used 16S-seq of eDNA, and metabolomics (LC-MS) to monitor sediment microbiomes throughout 2022.
We initially aimed to look at seasonal variations but ended up capturing the onset of the largest flood in the Murray-Darling Basin since the '50s.

The 2022 floods triggered shifts in the Coorong’s microbiome—similar to gut bacteria on new diets—revealing why freshwater flows are vital to wetland health.

Our new paper on sediment nutrient cycling in the Coorong (using passive hydrogel [DGT/DET] samplers). Great work, Leslie & team!
Part of the brilliant Healthy Coorong Healthy Basin work recently completed, led by Luke Mosley through the #GoyderInstitute
