Core Ontological Distinctions
1. Ecad (Ecophene) vs. EcotypeEcads (Ecophenes) are genetically identical individuals of the same species that look different solely due to temporary, reversible environmental plasticity. Ecotypes are genetically distinct local populations adapted to specific environments; their traits are fixed and heritable.
2. Ecotone vs. EcoclineAn Ecotone is a relatively sharp physical transition zone (zone of tension) between two distinct ecosystems (e.g., Mangrove or Estuary). An Ecocline is a gradual, continuous change in community composition along an environmental gradient (such as altitude or water depth) without a sharp boundary.
3. Biome vs. Biogeographic RealmA Biome is defined by climate and vegetation structure (e.g., Tropical Rainforests in both Amazonia and Congo). A Biogeographic Realm (e.g., Neotropical vs. Afrotropical) is defined by shared evolutionary history, taxonomy, and continental barriers.
