The biophysics of plant–fungus symbiosis: from the LCO → Ca²⁺ signalling cascade in a single cell to the spectral graph theory of the forest "wood-wide web". Eight modules with live FastAPI/SciPy simulations on the cell and forest pages.
An accessible introduction. Trees, fungi, the Wood-Wide Web, mother trees, and the cooperation-vs-competition debate. No calculus required.
The 5-step molecular handshake: strigolactones → LCO → nuclear Ca²⁺ oscillations → CCaMK → arbuscule formation.
Whole-cell model coupling carbon, phosphorus, nitrogen and signalling. Live simulation with sliders on this page.
CCaMK as a biological matched filter — the memory-kernel decoder that distinguishes fungal signal from cellular noise.
Graph Laplacian, Fiedler λ₂, Villani hypocoercivity, HWI inequality. Live forest network simulation on this page.
Scale-free networks are robust to random failure but fragile to targeted attack. The mathematical case for protecting hub trees.
Inside the exchange interface: proton motive force, polyphosphate vacuoles, GS–GOGAT, aquaporins, jasmonate defence, biological markets.
From Simard's Finding the Mother Tree to Villani's Hypocoercivity — a complete reading list at every level.
