Coalescent Neuron · Axon
Spiking-neuron oscillator on the FitzHugh-Nagumo system: relaxation oscillator + excitable (trigger-fired) voice
Coalescent Neuron · Soma
Bursting/chaotic neuron oscillator on the Hindmarsh-Rose system: spike trains, bursts, and chaos from one current control
Coalescent Operon
Three-phase oscillator on the repressilator gene circuit: three genes repressing each other in a ring, ~120 degrees out of phase
Coalescent Bunnies
Predator-prey oscillator: prey and predator chase each other a quarter cycle apart. Lotka-Volterra and Rosenzweig-MacArthur modes.
Coalescent Foxes
Three-species food chain (Hastings-Powell): grass, bunnies, and foxes move from a regular chase through period doubling into deterministic chaos.
Coalescent Finches
Trait-density ecology: mutation and frequency-dependent competition turn one phenotype into two persistent clusters.
Coalescent Islands
Four-island Wright-Fisher drift: bounded stochastic allele-frequency CV with selection, mutation, migration, and founder bottlenecks.
Coalescent Archipelago
Eight-habitat local adaptation: selection follows a spatial environmental gradient while mutation, nearest-neighbor migration, climate, and a barrier shape clines and range shifts.
Coalescent Lineages
Generative ancestral-tree sequencer: sampled traits coalesce backward into a common ancestor or branch forward through neutral mutation.
