Microbial 'phosphorus gatekeeping' found at center of study exploring 700,000 years of iconic coastline

A team of researchers investigated a sequence of coastal dunes of different ages (from 0-700,000 years old) in Cooloola National Park near Rainbow Beach to understand how soil microorganisms coped with severely declining levels of nutrients such as phosphorus in soil as the dunes got older. They found microbes -- such as fungi and bacteria -- acted is 'phosphorus gatekeepers' to deal with low phosphorus levels.
