Light Intensity Modulates Locomotor Behavior and Predation in Different Color Morphs of the Harlequin Ladybird, Harmonia axyridis

open access: yesInsects
Light is a fundamental ecological cue for insects, influencing physiological rhythms and behavior. We investigated how varying light intensities affect locomotion and foraging in H. axyridis color morphs, and examined the role of visual opsins.

Genetic diversity and outlier loci detecting of shell color variation in the Pacific oyster (Crassostrea gigas) by SNP markers★

open access: yesAquatic Living Resources, 2017
Color polymorphism is relatively common in marine mollusks. Shell color affects the visual perception of products which, consequently, influences consumer preference and product value.

Negative frequency-dependent selection maintains a dramatic flower color polymorphism in the rewardless orchid Dactylorhiza sambucina (L.) Soo

open access: yes, 2001
The orchid Dactylorhiza sambucina shows a stable and dramatic flower-color polymorphism, with both yellow- and purple-flowered individuals present in natural populations throughout the range of the species in Europe.

Estimation of Selection Intensity Against Dark Color Forms of the Spittlebug Philaenus spumarius (L.) in a Warming Climate

open access: yesInsects
Climate warming puts new selective pressures on natural populations, but there are few quantitative measurements of selection in natural populations over protracted time periods.

El polimorfismo en el color de frutos de Gaultheria mucronata (L.f.) Hook. & Arn. no afecta su germinación predispersiva

open access: yesGayana: Botanica, 2022
The germinative dynamics of Gaultheria mucronata (L.f.) Hook. & Arn. seeds from fruits of different colors were compared. Seeds from white, pink and dark-pink fruits were subjected to germination trials, evaluating the final germination percentage ...

Pollinator response to flower color polymorphism and floral display in a plant with a single-locus floral color polymorphism: consequences for plant reproduction [PDF]

open access: yes, 2012
Variation in flower color, particularly polymorphism, in which two or more different flower color phenotypes occur in the same population or species, may be affected or maintained by mechanisms that depend on pollinators. Furthermore, variation in floral

Functional assessment of human coding mutations affecting skin pigmentation using zebrafish.

open access: yesPLoS ONE, 2012
A major challenge in personalized medicine is the lack of a standard way to define the functional significance of the numerous nonsynonymous, single nucleotide coding variants that are present in each human individual.

Molecular basis of green-brown color polymorphism in grasshoppers [PDF]

open access: yes
A century and a half after Darwin's On the Origin of Species, the question of how phenotypic variation is generated and maintained remains central to evolutionary biology.

Influence of technology, color architecture and bit-depth of optoelectronic imaging sensors used as color measurement instruments [PDF]

open access: yes, 2005
Digital image capture devices cannot be used directly as instruments for color measurement. The main stages for characterizing a digital image capture device as an instrument for color measurement are the spectral and spatial characterization and the ...
