註釋
The surface of dry or wet asphalt roads reflect partially linearly polarised light, the degree of linear polarisation of which depends on the darkness and roughness of asphalt - the darker and/or the smoother the asphalt, the higher the p of light reflected from it. If the asphalt is sunlit and the direction of view is parallel to the solar-antisolar meridian, then the direction of polarisation of asphalt-reflected light is horizontal. In this case the asphalt surface can attract water-seeking aquatic insects, because they detect water by means of the horizontal polarisation of light reflected from the water surface. This phenomenon is called positive polarotaxis. This book proposes the use of these remedies on asphalt roads running near emergence sites of endangered aquatic insects, especially in the vicinity of wetlands, rivers and lakes.
