Table 7 Heat map showing the number of studies including interventions/exposures with each light wavelength, flashing pattern, and combinations of wavelengths and flashing patterns

From: Effects of artificial light on bird movement and distribution: a systematic map

  1. Blue shading represents the number of studies with each wavelength, from 1(light blue) to 309 (dark blue). Yellow/red shading in columns three through seven represents the number of studies with each wavelength/flashing pattern combination, from 1 (pale yellow) to 61 (red). The TOTAL row shows the number of studies with each flashing pattern. The total is less than the sum of the columns because some studies included multiple wavelengths. UV + treatments added UV wavelengths to broad spectrum white light
