Disturbance interactions have profound consequences for forest health, yet remain poorly understood.

Here we use DAGs to differentiate #Synergisms, #CompoundDisturbances & #NetworkEffects and review the impacts of climate change.

Land-use change is the main cause of deforestation in the Amazon, but the risk of abrupt forest decline, along with its potentially devastating consequences, increases as the planet warms, with a strong nonlinear trend beyond 2.3° C of warming. In PNAS: https://ow.ly/6Prr50XKAN1

🚨 What if evolution is the ”law”… and networks are the machines that do the work?

In this paper (just published) I try to formalize how living systems are non-equilibrium, information-processing, adaptive matter. With a great biological flavor! 🧪🌐🌍🧬🦠

Forest structural and functional diversity can attenuate forest productivity losses after harvesting and fires. In undisturbed forests, dominance boosts productivity via selection effects, but not after harvesting🌳🌲🌍

Old-growth forests 🌲store lots of carbon and support biodiversity. Recent study of 3,503 tree rings across Europe shows that older forests, especially those with large trees, are crucial for long-term carbon storage, highlighting the need to protect them.👍

Fascinated to learn that we are still discovering new species at the highest rate ever. Mapping Earth's biodiversity is far from over, and while we learn more and more about it, let's protect what we do know as well as we can!

Watched S5 E1 ("The Crawl") of #StrangerThings last night & was thrilled to see gorgeous examples of drill holes made by a yellow-bellied sapsucker (Sphyrapicus varius) in the trunk of what's likely a loblolly pine (Pinus taeda); Will Byers (Noah Schnapps) for scale. 🧪🌲🪵🐦🕳️
