the accumulation and composition of berry anthocyanin was measured in vitis vinifera l. cv. yatomi rosa using various light qualities provided by polyethylene films (red, orange, green, blue, and white). the anthocyanin has been enhanced significantly by blue light filter film and suppressed by red, orange, and green films compared to white film (control), which suggests that yatomi rosa has ad...

A literature review concerning perception of coloration is presented. In the paper we also present a review of general psycho acoustic background material concerning auditory modeling including perception of timbre and amplitude modulation. Furthermore, some classical room acoustic measures for echo perception are considered. Finally, some of the simple engineering measures to rate coloration i...

Two recent articles by Geisler and Diehl use Bayesian statistical decision theory to model the co-evolution of predator and prey in a simple, game-like environment. The prey is characterized by its coloration. The predator is characterized by the chromatic sensitivity of its visual system and its willingness to attack. The authors demonstrate how the coloration of prey and the perceptual system...

Background Efficient communication requires that signals are well transmitted and perceived in a given environment. Natural selection therefore drives the evolution of different signals in different environments. In addition, environmental heterogeneity at small spatial or temporal scales may favour phenotypic plasticity in signaling traits, as plasticity may allow rapid adjustment of signal ex...
