Article Synopsis
- A solitary population of consumers tends to evolve an intermediate phenotype within a resource gradient, unlike competing species that diverge phenotypically.
- Theory suggests that negative frequency-dependent selection helps maintain this intermediate phenotype by favoring rarer extremes, but this concept hasn't been thoroughly studied in allopatric populations.
- An experiment with threespine sticklebacks showed slight evidence for frequency-dependent survival effects, but not on growth rates, indicating that other forms of selection might better explain the maintenance of intermediate phenotypes in these populations.
We present a colourimetric litmus test for simple differentiation of organic liquids based on wetting, which achieves chemical specificity without a significant sacrifice in portability or ease-of-use. Chemical specificity is derived from the combination of colourimetric wetting patterns produced by liquids in an array of inverse opal films, each having a graded wettability, but using different surface groups to define that gradient.
