Core Ontological Distinctions
1. Liebig's Law of Minimum vs. Shelford's Law of ToleranceLiebig's Law (1840) focuses strictly on scarcity—growth is dictated by the single essential nutrient present in the smallest relative amount. Shelford's Law (1913) expands this to both extremes: too much of a factor (heat, water, salt) is just as lethal as too little, creating a bell-shaped zone of tolerance.
2. Resistance vs. ResilienceResistance (Inertia) is an ecosystem's ability to remain unchanged while being subjected to a disturbance (like a mature oak forest resisting a mild ground fire). Resilience (Elasticity) is the speed at which an ecosystem bounces back to equilibrium after being severely altered (like a grassland regrowing rapidly after a wildfire).
3. Acclimatization vs. AdaptationAcclimatization occurs within a single organism's lifetime and is reversible (e.g., a mountaineer producing more red blood cells at high altitude). Adaptation occurs across many generations via natural selection and is genetically fixed (e.g., native Tibetan highlanders or snow leopards).
