Data on eye movements of glaucoma patients with asymmetrical visual field loss during free viewing.
<p>Raw eye tracking data and processed eye movement data were recorded from fifteen participants with assymmetrical visual field loss (visual field worse in one eye) while they freely viewed 270 images of nature with each eye monocularly.</p>
Supplementary data for: Selection on visual opsin genes in diurnal Neotropical frogs and loss of the SWS2 opsin in poison frogs
<p><span></span></p> <p><span></span></p> <p>Amphibians are ideal for studying visual system evolution because their biphasic (aquatic and terrestrial) life history and ecological diversity expose them to a broad range of visual conditions. Here we evaluate signatures of selection on visual opsin genes across Neotropical anurans and focus on three diurnal clades that are well-known for the concurrence of conspicuous colors and chemical defense (i.e., aposematism): poison frogs (Dendrobatidae), Harlequin toads (Bufonidae: <em>Atelopus</em>), and pumpkin toadlets (Brachycephalidae: <em>Brachycephalus</em>). We found evidence of positive selection on 44 amino acid sites in LWS, SWS1, SWS2, and RH1 opsin genes, of which one in LWS and two in RH1 have been previously identified as spectral tuning sites in other vertebrates. Given that anurans have mostly nocturnal habits, the patterns of selection revealed new sites that might be important in spectral tuning for frogs, potentially for adaptation to diurnal habits and for color-based intraspecific communication. Furthermore, we provide evidence that SWS2, normally expressed in rod cells in frogs and some salamanders, has likely been lost in the ancestor of Dendrobatidae, suggesting that under low-light levels, dendrobatids have inferior wavelength discrimination compared to other frogs. This loss might follow the origin of diurnal activity in dendrobatids and could have implications for their chemical ecology, biodiversity, and behavior. Our analyses show that assessments of opsin diversification in understudied groups could expand our understanding of the role of sensory system evolution in ecological adaptation.</p>

Data from: Vomeronasal organ volume increases with body size and is dissociated with loss of a visual signal in Sceloporus lizards
<p>Many organisms communicate using signals in different sensory modalities (multicomponent or multimodal). When one signal or component is lost over evolutionary time, it may be indicative of changes in other characteristics of the signaling system, including the sensory organs used to perceive and process signals. <em>Sceloporus</em> lizards predominantly use chemical and visual signals to communicate, yet some species have lost the ancestral ventral color patch used in male-male agonistic interactions and exhibit increased chemosensory behavior. Here, we asked whether evolutionary loss of this sexual signal is associated with larger vomeronasal organ (VNO) volumes (an organ that detects chemical scents) compared to species that have retained the color patch. We measured VNO coronal section areas of 7–8 adult males from each of 11 <em>Sceloporus</em> species (4 that lost and 7 that retained the color patch), estimated sensory and total epithelium volume, and compared volumes using phylogenetic ANCOVA, controlling for body size. Contrary to expectations, we found that species retaining the ventral patch had similar relative VNO volumes as did species that have lost the ancestral patch, and that body size explains VNO epithelium volume. Visual signal loss may be sufficiently compensated for by increased chemosensory behavior, and the allometric pattern may indicate sensory system trade-offs for large-bodied species.</p>
