Theory

the model, from the ground up

What plant actually solves, and why. Consolidates material currently scattered across papers and vignettes.

Core

The demographic and physiological machinery shared by every strategy.

• The size-structured PDE — demography of individuals, patches, and metacommunities.
• Assimilation & hydraulics — the leaf-level carbon and water economy.
• Adaptive dynamics — invasion fitness and evolutionary endpoints.

Models

The physiological strategies that plug into that machinery — each a concrete set of growth, fecundity, and mortality functions. See the models overview.

• FF16 — the trait-based functional-balance model.
• K93 — Kohyama’s basal-area competition model.
• TF24 — the hydraulically-coupled leaf model.

Implementation

How the equations are solved numerically. See the implementation overview.

• The characteristic method
• ODE stepping & control
• The node-spacing algorithm
• Canopy & light-environment models
