• Ammophilia — An ecological and physiological property or preference of certain plant, animal, or microorganism species to live and develop exclusively or predominantly in sandy soils or sand dunes. This phenomenon involves complex evolutionary structural adaptations, such as highly extended root systems for water acquisition or protective mechanisms against mechanical abrasion caused by moving sand grains.
