Sentence examples for colour signals from inspiring English sources

In humid temperate regions, well-drained soil profiles near a summit can have thick E horizons (the leached layers) overlying well-developed clay-rich Bt horizons, while poorly drained profiles near a toeslope can have thick A horizons overlying extensive Bg horizons (lower layers whose pale colour signals stagnation under water-saturated conditions).

These two colour signals are used as analytical parameters for the subsequent computer processing and model calibration.

Instead of being an effect of evolutionary colour signals, the new claim was that the difference in performance was due entirely to the visibility of the different colours.

The abstract colour signals depicted similar radical chemiluminescence behaviour variations along with changes in equivalence ratio, reactant composition, and the increase of heat-release in the reactant flow.

On US and colour Doppler examination a phlegmon appears as a hypoechoic mass with no identifiable wall and internal colour signals.

Birds presented with mealworms with secreted defences learned to avoid unpalatable prey on the basis of their colour signals more quickly than birds presented with mealworms with stored defences.

We gave two groups of starlings a sequential colour discrimination task, where one colour signalled palatable mealworms and the other signalled mealworms that had been either injected with or coated with quinine solution (designed to simulate prey that stored and secreted their chemical defences, respectively).

Here's the best part: if it's true that facial bare skin evolved to allow for colour signalling, then other trichromatic primates should have visible skin too.

Even if bare skin was initially selected for something other than colour signalling, it is likely the case that both colour vision and visible skin became evolutionarily entangled, at least among primates, argues Changizi.

However, the important question remains, do these changes affect colour signalling?

Colour vision is compromising sensitivity since the colour signal requires a comparison between signals from photoreceptor types with different spectral sensitivities.
