Visual Ecology

Visual ecology is the study of how organisms use light to acquire information, and how the visual properties of environments shape the evolution of sensory systems, signaling strategies, and behavioral patterns. It encompasses the physics of light propagation through water, air, and vegetation; the physiology of photoreceptors and neural processing; and the behavioral ecology of visual communication, camouflage, and predator detection. Like acoustic ecology, visual ecology treats the sensory environment as a co-constructed niche: organisms evolve visual systems matched to their habitats, and they modify those habitats (through bioturbation, canopy architecture, or coloration) in ways that alter the visual information available. The degradation of visual habitats by light pollution is an emerging concern, paralleling acoustic habitat loss in its structural disruption of sensory connectivity. See Photopollution.
