Wolf — completes the food chain: grass → deer → wolf. diet_type: carnivore, diet_breadth: ["herbivore"], body_mass_kg: 40. Predation template matches wolf→deer automatically. Deer flee response triggers from carnivore detection. Expected emergent dynamic: Lotka-Volterra oscillations, trophic cascade (wolves reduce deer → grass recovers).
Songbird — new trophic niche: insectivore + frugivore. diet_breadth: ["pollinator", "forb:fruiting"], body_mass_kg: 0.025. Tests insectivory mass-ratio window (predator >> prey, unlike mammalian predation). Expected: songbird-butterfly predation reduces pollination pressure.
Mushroom — closes the nutrient loop. diet_type: decomposer, targets organic_matter voxel layer. r_selected (clutch_size 5, fast generation). Accelerates mineralization rate locally. Expected: measurably faster soil recovery near decomposer clusters, 3–4× reduction in ecosystem recovery time after collapse events.
