.... We also found a ∼25 nm diurnal shift in spectral sensitivity towards longer wavelengths in the evening in both ERG and intracellular recordings. Whether the shift is caused by screening pigment migration or changes in opsin expression remains unclear, but the observation shows the diel dynamism...

.... Crystalline cone Pupil Rhabdom Screening pigment Ants of the genus Myrmecia rely heavily on vision for prey capture ( Eriksson, 1985 ; Via, 1977 ) and navigation ( Narendra et al., 2013b ; Reid et al., 2011 ; Zeil et al., 2014 ). This is reflected in the size of their eyes, with some species...

... heterogeneity yellow tip orange tip screening pigment The Rhopalocera (butterflies) is a recently evolved group in the order Lepidoptera ( Grimaldi and Engel,2005 ). It contains the day-flying true butterflies(Papilionoidea), the skippers (Hesperioidea), and a newly identified group of the nocturnal...

... Heliconius melpomene , the small white Pieris rapae and the small copper Lycaena phlaeas . The colour of the eye shine is determined mainly by the reflectance spectrum of the tapetal mirror and the transmittance spectrum of the photoreceptor screening pigments, if present near the light-guiding rhabdom...

...Ian G. Gleadall; Kohzoh Ohtsu; Etsuko Gleadall; Yasuo Tsukahara ABSTRACT The extent of screening-pigment (SP) migration in the intact octopus retina and the amplitude of the early receptor potential (ERP) correspond with the degree of adaptation to light or darkness. The light-adapted retina has SP...
