Mosaic of Size‐Dependent Mortality in Three Ecologically and Economically Important Pine Species Reveals Patterns Across Space and Time Aim Global forests face increasing stresses from novel climate states, altered disturbance regimes and the spread of pests and pathogens. Understanding where and when mortality occurs across species...

🌲 Very happy to share our new study on where, when, and why trees die across the range of 3 major southern US pines: Pinus taeda, P. palustris, and P. elliottii (loblolly, longleaf, and slash pine).

This is really something: using the longest available data (1971–2019) and disentangling causal influences, a tropical forest is shown to have flipped from a carbon sink to a carbon source due to increasingly extreme temperatures & cyclones!!!

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

Huge team effort led by the brilliant Fabian Fischer!

It turns out we shouldn't expect #eDNA to capture local diversity/composition of tropical trees but rather broad patterns across regions. Together with a fairly coarse taxonomic resolution, the utility of eDNA for biodiversity monitoring of tropical forest trees is probably limited.

Ever wonder about what spatial scale of biodiversity #eDNA 🧬 samples capture?

We did. So we used data from the 16-ha Luquillo Forest Dynamics Plot 🇵🇷 to investigate the spatial scale of soil eDNA samples for tree🌴🌳 diversity.

(Please share with #eDNA folks!)

🌿 Trees in valleys grew faster & died more.
🌿 Some valley species thrived “at home,” but community-level support was mixed.
🌿 Even 22 m elevation differences = meaningful demographic shifts.

Woody respiration is an important but unconstrained process in the forest carbon cycle. @mariabmills.bsky.social made real progress in Malaysian Borneo using lasers and climbing giants, so that you don't have to! She came away with great insights.

We quantify, map and analyse wood density across tropical South America.

Our analysis led by Martin Sullivan refines the east-west Amazon gradient in wood density, improves it by revealing much finer variation, & extends predictions to Andean, Dry & Atlantic forests.

In our new paper in @science.org, we show that tropical forests are changing over time, but too slowly to track climate change. Our article, led by @jeaggu.bsky.social just out:

As someone long interested in latitudinal gradient in forest diversity and dynamics it’s been really gratifying to see this paper come together over time- looking forward to the new research on forest dynamics I think this will inspire!
