How spatial patterns can lead to less resilient ecosystems | PNAS Several theoretical models predict that spatial patterning increases ecosystem resilience. However, these predictions rely on simplifying assumptio...

This shows why spatial context fundamentally changes how patterns shape tipping points.

By adding realistic finite boundaries & environmental anisotropies to theoretical models, plant interactions become non-reciprocal. This triggers nonlinear convective instabilities, making patterned landscapes MORE vulnerable to desertification fronts than uniform vegetation. (2/3) βš›οΈ

The answer to my previous post? Convective instabilities! πŸŒͺ️

I'm thrilled to share our new paper in PNAS! Alongside @rmtzgarcia.bsky.social, we challenge the dominant paradigm that spatial self-organization inherently increases ecosystem resilience. (1/3) πŸ§ͺ🌍

...we completely overlooked one feature hidden in this figure (check the state vs environmental stress $\eta$).

Can you guess what it is? πŸ‘€

During my postdoc, we finally figured it out! Stay tuned, I'll share the answer and our new paper later today. (2/2)

Topological defects law for migrating banded vegetation patterns in arid climates Distribution of defects in vegetation patterns could determine the ecosystem adaptation or collapse against environmental changes.

Hi #ScienceSky! πŸ‘‹ I'm a theoretical physicist & postdoc @ CASUS-HZDR working on complex systems, nonlinear dynamics & spatial ecology.

A while ago, we found that topological defects in vegetation patterns leave an imprint on drylands (www.science.org/doi/10.1126/...). But... (1/2) πŸ§ͺπŸ”¬
