Female mating preferences, lighting environment, and a test of the sensory bias hypothesis in the bluefin killifish.

摘要: Sensory drive proposes that environmental conditions affect signalling dynamics and the evolution of signals receivers. For visual systems, delineating effects lighting on mating preferences is difficult because can via three mechanisms: (1) genetic differentiation in result from selection under different conditions, (2) development alter system presumably female (3) immediately colour perception by filtering wavelengths altering backgrounds. We teased apart these crossing bluefin killifish within between a spring population swamp differed environment. divided offspring clear tea-stained rearing environments (developmental plasticity) measured preference tea (immediate effects). found differentiation: showed strong for red males. also three-way interaction genetics, developmental plasticity immediate blue males: had highest levels males when raised tested conditions. Thus, environment experienced during mate interact with genetics to determine preference. sensory bias hypothesis, which predicts evolve as correlated response nonmating behaviours such foraging. The relationship foraging was weak provided little support bias.
