Many thanks to @leverhulme.ac.uk for funding this work! Keep your eyes peeled for a quantitative test of some of these ideas usign airborne LiDAR, which is coming soon!

We have a #Tansley review out today @newphyt.bsky.social led by Becky Banbury Morgan in which we put forward a new framework that aims to explain how and why edge effects on forest structure vary across ecosystems and through time

New paper led by @corneliussenf.bsky.social out today @natcomms.nature.com shows that increasingly frequent waves of extreme forest dieback are predicted across Europe by Taylor's law of mean-var scaling applied to the past 35 years of satellite data.

[4/4] We also show that variation in canopy 3D structure & dynamics were tightly coupled across the landscape, with taller and more structurally heterogeneous canopies also experiencing faster rates of gap dynamics.

[4/4] We also show that variation in canopy 3D structure & dynamics were tightly coupled across the landscape, with taller and more structurally heterogeneous canopies also experiencing faster rates of gap dynamics.
[3/4] We found that canopy dynamics were strongly tied to topography, with rates of canopy growth & disturbance being 3–5 times greater in low-lying alluvial forests on fertile soils than in nearby nutrient-depleted forests on hilltops.

[2/4] We used repeat airborne laser scanning data acquired over a topographically diverse landscape in Borneo to track the gap dynamics & canopy growth trends of 1500ha of old-growth forests.

[1/4] Tropical forests can vary hugely in their 3D structure over surprisingly small scales due to subtle changes in topography that influence soil nutrients, water flow & exposure to wind. But the dynamic processes (growth, mortality & recruitment) that underpin this variation remain a big mystery.

[3/4] Tree height is primarily constrained by water availability and competition for light, with tropical forests in SE Asia home to disproportionately high concentrations of species with tall, slender growth forms. By contrast, crown width is predominantly shaped by exposure to wind and fire.

[2/4] We found that there are two largely orthogonal axes of crown architecture: one related to tree slenderness and height, and the other to crown width. Where trees fall within this spectrum depends on their environment, their ecological strategy and evolutionary history.

[1/4] Trees come in all shapes and sizes – from tall and slender to short with wide crowns. But what drives this huge diversity in crown architecture? To answer this we compared the crown allometries of nearly 2000 tree species.
