Microbial competition for phosphorus limits the CO2 response of a mature forest

NATURE Published: 05 June 2024 Abstract The capacity for terrestrial ecosystems to sequester additional carbon (C) with rising CO2 concentrations depends on soil nutrient availability1,2. Previous evidence suggested that mature forests growing on phosphorus (P)-deprived soils had limited capacity to sequester extra biomass under elevated CO2 (refs. 3,4,5,6),… Read More »Microbial competition for phosphorus limits the CO2 response of a mature forest

The Conversation: A fierce battle is being fought in the soil beneath our feet – and the implications for global warming are huge

Published: June 6, 2024 6.26am CEST As humanity continues to burn fossil fuels, the delicate balance of life on Earth is changing. That’s true of trees, many of which are growing faster as a result of increased carbon dioxide (CO₂) concentrations in our atmosphere. But… Read More »The Conversation: A fierce battle is being fought in the soil beneath our feet – and the implications for global warming are huge

Tropical rainforests show phosphorus key to understanding world’s ecosystems

A new international study led by Western Sydney University researchers has quantified phosphorus constraints to photosynthesis in tropical forests, highlighting how accounting for this constraint can improve the world’s climate. Tropical forests have an important role in the carbon cycle, absorbing more carbon from the… Read More »Tropical rainforests show phosphorus key to understanding world’s ecosystems

Five Years Of Findings Hint At Australia’s Future Response To Our Changing Atmosphere

“Without EucFACE, prediction models would rely on data gathered from experiments run in the northern hemisphere, which were based on richer soils…” Since its launch in 2012, the iconic EucFACE experiment, based at WSU’s Hawkesbury campus, has exposed a patch of native forest in north-west… Read More »Five Years Of Findings Hint At Australia’s Future Response To Our Changing Atmosphere

Elevated CO2 does not increase eucalypt forest productivity on a low-phosphorus soil

Nature Climate Change volume 7, pages279–282 (2017). Abstract: Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions1,2. Elevated CO2 experiments in temperate planted forests yielded ∼23% increases in productivity3 over the initial years. Whether similar CO2 stimulation occurs in mature evergreen broadleaved forests on low-phosphorus (P) soils is unknown, largely due… Read More »Elevated CO2 does not increase eucalypt forest productivity on a low-phosphorus soil

Our changing world

Gardening Australia Sat 14 Sep 2013. “I’m at the Hawkesbury Campus of the University of Western Sydney and the reason I’m here is because this is where we have some Australian groundbreaking research,” says Jerry. The first area he visits is essentially a surreal eucalypt… Read More »Our changing world
