Sentence examples for maintenance of colour from inspiring English sources

In birds for example, the maintenance of colour polymorphisms may be due to differential hunting success of colour morphs due to variation in light conditions [9].

Different female preferences for territorial traits, or differential investment by males in territoriality as opposed to other sexual signals might be expected to maintain genetic diversity in aggression, as has been demonstrated for maintenance of colour polymorphism in guppies [10].

The mechanisms responsible for the evolution and maintenance of colour polymorphisms in wild populations of animals have been the subject of intense research, especially in fish [2], reptiles [3] and birds [4].

Recent studies suggest a strong role for environmental heterogeneity in favouring the maintenance of colour polymorphisms [ 57- 59].

Here we aim to elucidate the relationship between colour polymorphism and immune function in order to understand the maintenance of colour polymorphisms.

Apostatic selection, the primary hypothesis for maintenance of colour polymorphism in cryptic animals, proposes that visual predators focus on common forms of prey, resulting in higher survival of rare forms.

Another potential explanation is gene flow or dispersal, which may counteract locally varying selection favouring the most cryptic morph, thereby contributing to the maintenance of colour-marking polymorphisms within populations of T. japonica.

This strongly suggests that in addition to colour and morphology imitation, behaviour imitation plays a crucial role in the maintenance of this colour polymorphism as has been previously suggested [ 33, 42].

The results of this study provide a mechanism for maintenance of cuticular colour variation in this species of beetle; darker cuticles are thicker, but their production is potentially limited by resource constraints and differential investments in resistance mechanisms between the sexes.

We propose that female colour polymorphism could be related to immune function and that selection on immune function and melanism could contribute to the maintenance of the colour polymorphism.

The objectives of the present study were to examine the spatial distribution of I. graellsii and I. elegans in the Iberian Peninsula, evaluate the extent of introgression of I. graellsii genes into the recently established I. elegans populations in Spain, and to understand the role of the hybridization on the temporal maintenance of female colour morph frequencies in both species.
