- ItemIt's not easy being blue: Are there olfactory and visual trade-offs in plant signalling?(San Francisco, CA : Public Library of Science, 2015) Valenta, Kim; Brown, Kevin A.; Melin, Amanda D.; Monckton, Spencer K.; Styler, Sarah A.; Jackson, Derek A.; Chapman, Colin A.Understanding the signals used by plants to attract seed disperses is a pervasive quest in evolutionary and sensory biology. Fruit size, colour, and odour variation have long been discussed in the controversial context of dispersal syndromes targeting olfactory-oriented versus visually-oriented foragers. Trade-offs in signal investment could impose important physiological constraints on plants, yet have been largely ignored. Here, we measure the reflectance and volatile organic compounds of a community of Malagasy plants and our results indicate that extant plant signals may represent a trade-off between olfactory and chromatic signals. Blue pigments are the most visually-effective – blue is a colour that is visually salient to all known seed dispersing animals within the study system. Additionally, plants with blue-reflecting fruits are less odiferous than plants that reflect primarily in other regions of the colour spectrum.
