biogeography

Layer 3 — Biology24 concepts in this subtree

Spatial distribution of species and higher taxa across geography and geological time. Bridge between ecology, evolution, and geology; informs conservation prioritisation and invasion risk.

Wallace line
Island biogeography (MacArthur–Wilson)
Endemism
Dispersal vs vicariance
Latitudinal diversity gradient
Biogeographic realm
Climate-driven range shift
MacArthur-Wilson equilibrium: dS/dt = c(P−S) − eS; island biogeography ODE framework
Rapoport's rule: R(φ) = a + b·|φ|; latitudinal-range-size regression framework
Fisher-KPP dispersal wave: ∂u/∂t = D·∂²u/∂x² + r·u·(1−u); traveling-front framework
MacArthur-Wilson theorem: S*=cP/(c+e); dS|₀=cP; dS|_P=−eP; τ=1/(c+e); c=e → P/2
Rapoport theorem: b_2pt=(y1−y2)/(x1−x2); b_std=ρσy/σx; (u1v2−u2v1)²≥0; 1−ρ²=−(ρ−1)(ρ+1)
FKPP theorem: c*=2√D·√r (split-radical canonical); c*|_{D=1}=2√r; c*|_{r=1}=2√D; λ_min=−√r/√D
