“…Other marine organisms such as scallops, possess pigment cup eyes, which have no lenses and are of simple design (Warrant & Locket, 2004). Many arthropods have compound eyes, a useful eye type for either aquatic or terrestrial environments (Yilmaz, Hempel de Ibarra & Kelber, 2022). Compound eyes are composed of several thousand optical units (ommatidia), which collect light efficiently and with great sensitivity (Warrant, 2004).…”

Light pollution is a pervasive global stressor to natural systems. However, due to the proximity of human activities along the coasts and open ocean, light is a pervasive yet commonly overlooked pollutant in many marine habitats. There is a well‐developed body of literature on the visual physiology, behaviour and ecology of many marine taxa, and a re‐evaluation of these data can help inform risks of light pollution to impact marine organisms and ecosystems. This paper identifies key knowledge gaps in the study of marine light pollution ecology and recommends research and management foci for future study. Most work on this pollutant has focused on terrestrial ecosystems and taxa, where experts have learned how anthropogenic light influences behaviour, reproduction cycles and population dynamics. However, light pollution bleeds far beyond the shores, affecting many sensitive ecosystems with light available at unnatural times with varied makeup, such as varying intensities or spectra. This review discusses the current understanding of light dynamics underwater, photoreceptive systems of marine taxa and the documented ecological impacts. This lends a critical basis of understanding for the many gaps in marine light pollution biology. For example, little is known about effects of light on broad groups of marine taxa such as cetaceans, ecosystem‐level effects, or interactive impacts of light and other anthropogenic stressors. Light is a key structuring factor of the marine environment and can therefore elicit immense downstream effects on marine organisms individually, at the population‐ or ecosystem‐level. Light pollution is an urgent concern for marine ecosystems because marine organisms have tight relationships with their natural light environment. As the world moves deeper into the Anthropocene, assessing and mitigating the risks of this pollutant to key environmental and economic marine systems is critical to maintaining a healthy ocean.

“…Color vision and color preference have been subjects of research interest for over a century (reviewed by Staples, 1931). Decades of research have confirmed color vision in most vertebrates and arthropods (Kelber, Vorobyev, & Osorio, 2003, Baden & Osorio, 2019, Yilmaz et al, 2022. The presence of color vision in a species does not automatically suggest the presence of color preference, but to have color preference, the faculty of color vision is essential.…”

Most of the research on color vision related behaviors in dogs has involved training the dogs to perform visual discrimination tasks. We investigated the meaning of color to untrained Indian free-ranging dogs (FRDs). Using one-time multi-option choice tests for color preference in 134 adult dogs, we found the dogs to prefer yellow objects over blue or gray ones (p < 0.001, Cramer's V = 0.433) while there was no preference between blue and gray (N = 102, p = 0.165). We next pitted a yellow object against a gray object that had food. Here, the dogs ignored the food to approach the yellow object first, both when the food was biscuit (N = 52, p < 0.001, Cramer's V = 0.576) and chicken (N = 61, p < 0.001, Cramer's V = 0.540), indicating the color preference to be quite strong. Color preference has previously been investigated in many other animals and has implications for behaviors like mate choice and foraging. Our study provides a new perspective into the ecology of Indian FRDs and might have implications for pet dogs as well, if they too show this preference.

“…While flying within the constraints of their limited spatial acuity, bees have to process visual information, such as edges, to orientate and maintain flight stability [ 23 , 26 ]. Arthropods mainly use colour information for discriminating and recognizing objects against the background [ 27 ]. These objects may include obstacles on an insect's flight path or camouflaged prey [ 28 ].…”

Ancient insect vision tuned for flight among rocks and plants underpins natural flower colour diversity

Understanding the origins of flower colour signalling to pollinators is fundamental to evolutionary biology and ecology. Flower colour evolves under pressure from visual systems of pollinators, like birds and insects, to establish global signatures among flowers with similar pollinators. However, an understanding of the ancient origins of this relationship remains elusive. Here, we employ computer simulations to generate artificial flower backgrounds assembled from real material sample spectra of rocks, leaves and dead plant materials, against which to test flowers' visibility to birds and bees. Our results indicate how flower colours differ from their backgrounds in strength, and the distributions of salient reflectance features when perceived by these key pollinators, to reveal the possible origins of their colours. Since Hymenopteran visual perception evolved before flowers, the terrestrial chromatic context for its evolution to facilitate flight and orientation consisted of rocks, leaves, sticks and bark. Flowers exploited these pre-evolved visual capacities of their visitors, in response evolving chromatic features to signal to bees, and differently to birds, against a backdrop of other natural materials. Consequently, it appears that today's flower colours may be an evolutionary response to the vision of diurnal pollinators navigating their world millennia prior to the first flowers.
