Core Ontological Distinctions
1. Turnover Rate (K) vs. Turnover Time / Residence Time (T)Turnover Rate ($K = F / M$) is the fraction of a pool (biomass, nutrients, or species) replaced per unit time. Turnover Time ($T = 1 / K = M / F$) is the reciprocal: the time required to completely replace the standing stock. Open ocean phytoplankton have a massive turnover rate (high $P/B$) and tiny turnover time (days), whereas mature forests have a low turnover rate and long turnover time (decades).
2. True Spatial Turnover vs. Nestedness (Baselga Partitioning)Both create Beta Diversity between sites, but True Turnover means species at Site A are actively replaced by different species at Site B (requiring multiple protected areas). Nestedness means Site B is simply a species-poor subset of the richer Site A with no new species added (prioritizing protection of the richest source site).
3. Facultative vs. Obligate Mutual DependenceFacultative Mutualism (Protocooperation) benefits both partners, but each can survive independently or switch partners in a nested network. Obligate Symbiosis (e.g., Fig–Fig Wasp, Coral–Zooxanthellae, Termite–Trichonympha) is so tightly locked that the loss of one partner triggers immediate co-extinction of the other.
