DOI: 10.1007/s10682-017-9904-5
Abstract: Colour variation is frequently observed in spiders. Such variation can impact fitness by affecting the way spiders are perceived by relevant observers such as prey (i.e. by resembling flower signals as visual lures) and predators… read more here.

DOI: 10.1098/rspb.2023.1995
Abstract: The maintenance of colour variation in wild populations has long fascinated evolutionary biologists, although most studies have focused on discrete traits exhibiting rather simple inheritance patterns and genetic architectures. However, the study of continuous colour… read more here.

Beyond morphs: Inter‐individual colour variation despite strong genetic determinism of colour morphs in a wild bird

DOI: 10.1111/jeb.14124
Abstract: Categorizing individuals into discrete forms in colour polymorphic species can overlook more subtle patterns in coloration that can be of functional significance. Thus, quantifying inter‐individual variation in these species at both within‐ and between‐morph levels… read more here.

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

DOI: 10.1111/mec.17334
Abstract: Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue… read more here.

DOI: 10.1111/plb.13509
Abstract: Invasive plants displaying disparate pollination environments and abiotic conditions in native and non-native ranges provide ideal systems to test the role of different ecological factors driving flower colour variation. We quantified corolla reflectance of the… read more here.

Through the eye of a lizard: hue discrimination in a lizard with ventral polymorphic coloration
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Experimental Biology"
DOI: 10.1242/jeb.169565
Abstract: ABSTRACT Colour polymorphisms are thought to be maintained by complex evolutionary processes, some of which require that the colours of the alternative morphs function as chromatic signals to conspecifics. Unfortunately, a key aspect of this… read more here.

DOI: 10.17491/jgsi/2025/174243
Abstract: The Triassic red mudstones from the four master basins of Indian Gondwana occur in spectacular colours ranging from green to purple, including all shades of red. The purple colour of mudstones is caused by a… read more here.
