“…In general terms, Dipteran spectral sensitivity would limit color discrimination to wavelengths less than 600 nm 50 . Color recognition and preference have been noted in Drosophila melanogaster with strong color discrimination and sensitivity occurring between 406 nm and 505 nm 41,50–55 . Our preliminary studies of D. suzukii suggest that its visual range is comparable to that of D. melanogaster and set the stage for the behavioural experiments which form the bulk of this study.…”

Drosophila suzukii Matsumura (Diptera: Drosophilidae) is a significant invasive pest in soft-skin fruits and berries in Asia, Europe, and North and South America. Many herbivorous insects use multiple cues for host selection, particularly olfactory and visual stimuli. The visual system of closely-related Drosophila melanogaster is well-documented, expressing strong sensitivity to short-wavelength colors (ultraviolet to green) and only limited sensitivity to long-wavelength colors (red to infrared). Our results suggest that D. suzukii have limited ability to distinguish red consistent with visual sensitivity range within the melanogaster subgroup. We propose that color contrast rather than color appearance may be of greater importance in orientation and attraction. We propose that differences in reflectance between light wavelengths important for color opponency are key to color discrimination to provide color contrast between foreground and background, as occurs between fruit and foliage, during host-finding.

“…This dye was chemically manufactured, and thus, the toxicity effects are likely due to toxic chemical elements as opposed to natural compounds tested here. Marcus et al, (2018) showed that female Drosophila preferred to lay eggs on green over blue and aqua-coloured sheets placed under clear agar, highlighting the importance of colour itself for egg allocation and egg-laying for the species. We did not observe this effect with a higher incidence of laying in the control and red dye diets when compared with flies housed with green and blue diets.…”

Prolonged exposure to food dyes, even for those considered safe for consumption, are known to have toxic effects. However, we lack a proper understanding of the underlying compounds that are responsible for the observed toxicity. In this study, we tested the toxic physiological effects of three common commercially available natural food dyes (red, green, blue), and their main ingredients (turmeric and spirulina), onDrosophila melanogasteroviposition, larval development, and larval foraging behaviour. Larval development and egg-to-adult survival was significantly impacted by blue and green dyes. These effects were recapitulated when flies were fed with increasing concentrations of turmeric and spirulina, suggesting that turmeric is a toxic component of the food dye. Red dye, which contains neither turmeric or spirulina, had little impact on fly health and behaviour. Green and blue food dyes decreased egg laying, an effect similar to that observed in increasing concentrations of turmeric and, to a lesser extent, spirulina. When given a choice, larvae preferred to feed as follows: control > red > blue > green diet patches, a pattern inversely correlating with the previously observed toxicity. Our results show that, despite turmeric being often considered a super food, it can have toxic effects that the impact organismal physiology and health.

“…This conclusion illustrates the value of experimental evolution studies, which provide tractable experimental systems to develop proof of concept models (Zuk and Travisano, submitted). Using simplified experimental systems over evolutionary time, the causes and consequences for preferences (Marcus et al 2018), diversity and competitive ability (Lensk and Burnham 2018) and system collapse can be disentangled (this study). The success of these studies demonstrates there are abundant opportunities for further advances.…”

Rapid adaptation to near extinction in microbial experimental evolution

et al. 2017

Theory indicates that responses to natural selection maximize immediate fitness benefits, leading to adaptations to current environmental conditions and those of the immediate past. Over a century of advances in theory, experiment, and observation have documented innumerable adaptations demonstrating the efficacy of natural selection to finely tune species to their respective environments. However, theory also suggests that natural selection is not a panacea, and that improvements in competitive ability do not necessarily increase long-term survival. Here we show that adaptation in experimental populations of microbes can dramatically reduce population sizes to near extinction levels in a stressful environment. The long-term potential for extinction differed from that identified in short-term ecological observations, but the eventual outcome is consistent with limitations on specific modes of adaptation. These results suggest that additional emphasis on the limitations of adaptation can provide insight on when and how improvements in competitive ability provide longerterm benefits.
