Color polarization vision mediates the strength of an evolutionary trap.

摘要: Evolutionary traps are scenarios in which animals fooled by rapidly changing conditions into preferring poor-quality resources over those that better improve survival and reproductive success. The maladaptive attraction of aquatic insects to artificial sources horizontally polarized light (e.g., glass buildings, asphalt roads) has become a first model system scientists can investigate the behavioral mechanisms cause occur. We employ this field-based experimentally (a) portion(s) spectrum polarizationally water-imitating reflectors attractive nocturnal terrestrial aquatics insects, (b) modern lamp types result greater typical kind pollution. found most taxa exhibited preferences for lamps based upon their color spectra, having lowest preference emitting blue red light. Yet, despite previously established higher degrees polarization reflected light, insect families were attracted unpolarized spectrum. Chironomid midges, alone, showed lamplight both spectra indicating only family evolved use range as source information guide its habitat selection. These results demonstrate lighting exacerbate or reduce attractiveness but strength evolutionary traps, so demographic consequences, is primarily driven This focuses management attention on limiting broad-spectrum pollution, well intentional deployment attract back natural habitats.
