environmental-enrichment
Environmental enrichment refers to the practice of exposing organisms to more complex, stimulating physical and social surroundings to promote developmental and physiological changes. In plant science, this concept is applied to study how varied environmental conditions—such as diverse light spectra, mechanical stimuli, or neighboring plant interactions—shape plant growth, signaling pathways, and adaptive responses. Understanding these effects helps researchers uncover how plants integrate external cues to optimize development and resilience.

Adding simple physical structures like gravel or rubber cords to fish tanks can boost the immune system of farmed rainbow trout, with rubber cord 'plants' proving especially effective at protecting fish health under crowded conditions.
Rubber cord enrichment significantly boosted immune activity (respiratory burst, peroxidase content, and lysozyme) in trout under double stocking density (p < 0.05)
Gravel substrate increased social interactions and triggered signs of inflammatory immune activation in head kidney immune cells
A negative correlation between cortisol and body size suggested social hierarchy formation, indicating behavioral changes driven by environmental enrichment
