ABSTRACT Visual signals are involved in many fitness-related tasks and therefore essential for survival species. Aquatic organisms ideal systems to study visual evolution, as the high diversity of spectral properties aquatic environments generates great potential adaptation different light conditions. Flatfishes an economically important group, with over 800 described species distributed globally, including halibut, flounder, sole turbot. The flatfish wide array they occupy provides excellent opportunity understand how this variation translates molecular vision genes. Using models we investigated inhabited by lineages have shaped evolution rhodopsin gene, which is responsible mediating dim-light transduction. We found strong evidence positive selection rhodopsin, was correlated both migratory behaviour several fundamental aspects habitat, depth freshwater/marine evolutionary transitions. also identified mutations that likely affect wavelength peak absorbance outline these shifts correlate response spectrum present habitats.

Cichlid fishes are a very diverse and species-rich family of teleost that inhabit lakes rivers India, Africa, South Central America. Research has largely focused on East African cichlids the Rift Lakes Tanganyika, Malawi, Victoria constitute biodiversity hotspots cichlid fishes. Here, we give an overview study system, research questions, methodologies. spans many disciplines including ecology, evolution, physiology, genetics, development, behavioral biology. In this review, focus range organismal traits, coloration phenotypes, trophic adaptations, appendages like fins scales, sensory systems, sex, brains, behaviors. Moreover, discuss studies phylogenies, plasticity, general evolutionary patterns, ranging from convergence to speciation rates proximate ultimate mechanisms underlying these processes. From methodological viewpoint, last decade brought great advances in fish research, particularly through advent affordable deep sequencing genetic manipulations. The ability integrate across traits disciplines, developmental biology ecology makes fascinating system.

Tuning the visual sensory system to ambient light is essential for survival in many animal species. This often achieved through duplication, functional diversification, and/or differential expression of opsin genes. Here, we examined 753 new retinal transcriptomes from 112 species cichlid fishes Lake Tanganyika unravel adaptive changes gene at macro-evolutionary and ecosystem level one largest vertebrate radiations. We found that, across radiation, all seven cone opsins-but not rhodopsin-rank among most differentially expressed genes retina, together with other vision-, circadian rhythm-, hemoglobin-related propose two palettes characteristic very shallow- deep-water living species, respectively, show that adaptations along major ecological axes, macro-habitat diet, occur primarily via variation a subset

The visual sensory system is essential for animals to perceive their environment and thus under strong selection. In aquatic environments, light intensity spectrum differ primarily along a depth gradient.

ABSTRACT Evolutionary transitions in water column usage have played a major role shaping ray‐finned fish diversity. However, the extent to which vision‐associated trait complexity and is coupled remains unclear. Here we investigated relationship between depth niche, eye size, molecular basis of light detection across Antarctic notothenioid adaptive radiation. Integrating phylogenetic comparative framework with data on size occupancy, provide support for an acceleration rate diversification nearly 20 million years after initial Our results further reveal that levels divergence are often highest closely related taxa. We analyzed opsin tuning site sequences found changes representing repeated instances independent phylogeny generally not associated habitat or species size. Collectively, our strongly multiple evolutionary pathways underlie visual adaptations this iconic

Abstract The wide-ranging photic conditions found across aquatic habitats may act as selective pressures that potentially drive the rapid evolution and diversity of visual system in teleost fish. Teleost fish fine-tune their sensitivities by regulating two components pigments, opsin protein chromophore. Compared with variation, chromophore usage has received little attention.
