Sentence examples for divergence in colour from inspiring English sources
These ecotypes exhibit adaptive genetically based divergence in colour, colour-pattern, body size and shape [ 24- 26] and also partial reproductive isolation [ 27- 29].
Alternatively, speciation might have been initially triggered by divergence in colour pattern with mimetic convergence a derived state acquired subsequent to speciation in the Florencia region.
Figures showing weak relationships between pairwise FST and geographic distance (a), and pairwise FST and divergence in colour morph composition (b).
Perhaps most notably, a number of studies have linked ecological and sexual divergence among African cichlids to divergence in colour vision genes, the opsins [ 31, 32].
Multiple matrix regression analyses revealed that genetic distance (pairwise FST) was not a significant predictor of divergence in colour morph frequencies in C. decresii (rpartial = 0.026, P = 0.470; Additional file 7: Figure S2).
Under the second scenario, an initial divergence in colour pattern associated with adaptation to different Müllerian mimicry rings became associated with further changes in ecology and hybrid inviability, eventually leading to speciation [ 12].
"Because of the contours of an eye," says Biss, "it has to be lit completely differently to a hairy leg or an antenna", which means the sections have to be carefully sewn together, allowing for divergences in colour and perspective.
Here, we tested predictions from the hypothesis that allopatric divergence in male colour is associated with corresponding divergence in preference.
One of the main assumptions of speciation models by sexual selection so far was that evolutionary divergence in female colour preference was driving the emergence of behavioural isolation [ 40].
Here, laboratory mate choice tests with allopatric populations of Pseudotropheus zebra and related nominal species were inconsistent with the predictions we derived from the hypothesis that parallel correlated divergence in male colour and female preferences had resulted in parallel speciation among these fishes.
Ożgo and Kinnison (2008) detected strong shell colour divergence in three open/sheltered habitat pairs in southeastern Poland that had presumably been established 18 28 years previously.
