• Allochore — A term used to describe an organism, particularly a plant or vegetable species, dispersed into territories outside its native range through external, non-biological, or accidental dispersion means (such as human activity, wind, or water currents). In structural ecology, it defines allochthonous species introduced into a new habitat, where they may become naturalized or invasive.
• Amensal — Belonging to or characteristic of amensalism; a biological organism, species, or population within an ecosystem that suffers negative effects, structural inhibition, or total destruction as a result of interacting with another species, while the latter remains completely neutral, being neither positively nor negatively affected. It represents the asymmetric inhibited element in a forced cohabitation relationship.
