📢New paper out in Landscape Ecology!
We show how wildfire effects on Mediterranean forests depend on pre-fire landscape structure and fire-severity variability. High fire severity variation reduces small/medium pre-fire patches but increases the size of larger ones!

Today, #MaraPaneghel has brightly defended her PhD entitled ‘Early post-fire regeneration dynamics of Mediterranean forests under current climate and future scenarios’ at @udl.cat. Congrats Mara for such an impressive field-based piece of work! It’s been a pleasure to share this adventure with you 🤗

🌳 New Tansley Insight!
What really limits tree growth—carbon source or sink? 🤔
I argue it’s not either/or but a distal → proximal continuum: from photosynthesis to transport and cell division, drivers act together to shape C allocation & growth 🌱🌍

The second paper from Ana L. Méndez’s PhD is just out. It highlights the role of fire refugia in the post-fire recovery of a non-serotinous pine, serving not only as seed sources but also as shelters that reduce the exposure of pine regeneration to abiotic stress.

We’ve been resampling the permanent plots established by Mara Paneghel during her PhD, shortly after the Santa Coloma de Queralt fire (2021). Mara is studying how climate warming (along with other factors) is influencing post-fire vegetation dynamics in Aleppo pine forests #fieldwork #permanentplots

How can we define a wildfire as extraordinarily large across regions?
What constitutes a large fire event varies regionally depending on biophysical attributes and fire response.
In our latest publication, we introduce a new approach using return periods to identify contextually large fires. ⬇️

I really enjoyed visiting these sub-Mediterranean Pinus nigra stands located in the Catalan Pre-Pyrenees (Solsonès region). I was happy to see the forest owner as proud of his tall, straight trees as he was of the beautiful Acer opalus growing here and there adding some color to the understory.
