Our global meta-analysis is finally out - we explore the most important influencer on C4 photosynthetic capacity using ~1700 C4 Aci curves! Data are freely available for the community.

Environmental conditions drive variation in C4 photosynthetic capacity more than species traits

One more! Here the stellar Laura Williams leads a review of detection + attribution of change in Australian vegetation. The upshot: with current monitoring, it's remarkably difficult to attribute effects of climate - which has important consequences for management

"It isn't that the alarm bells are about to ring. They already have & if these last 2 fires are not enough to scare the pants off you, I don't know what is."

VIC's mountain forests are on the brink of collapse due to frequent bushfires & lack of regeneration support.

Alpine forests face collapse without urgent reforestation, say scientists

Bushfires and a lack of seed have created a "ticking time bomb" in Victoria's alpine and mountain ash forests, scientists are warning.

Our new research shows that forest recovery from tree mortality has slowed in recent decades. This reduction is primarily associated with rising temperatures and increased water scarcity. Recovery of forest canopy water content lags behind that of vegetation greenness

Nature research paper: Widespread slow growth of acquisitive tree species

https://go.nature.com/43Tc3GY

Widespread slow growth of acquisitive tree species - Nature

Under field conditions, acquisitive tree species generally grow slowly, whereas conservative species show generally higher realized growth, owing to their ability to tolerate unfavourable environmental conditions.
