... of the findings is hard to explain because the proximate background of within-species colour differences is very scarcely studied. We combined measurements of feather macrostructure and nanostructure to explain within-population variability in blue tit crown reflectance. We found that sexual dichromatism...

...Mingxia Sun; Gregory S. Watson; Yongmei Zheng; Jolanta A. Watson; Aiping Liang SUMMARY This study has investigated the wettability of forewings of 15 species of cicadas, with distinctly different wetting properties related to their nanostructures. The wing surfaces exhibited hydrophilic or weak...

...Richard O. Prum; Rodolfo Torres SUMMARY Structural colours of avian skin have long been hypothesized to be produced by incoherent (Rayleigh/Tyndall) scattering. We investigated the colour,anatomy, nanostructure and biophysics of structurally coloured skin,ramphotheca and podotheca from 31 species...
