In 1974, Cartmill introduced the theory that the earliest primate adaptations were related to
their being visually oriented predators active on slender branches. Given more recent data …

All mammalian cone photopigments are derived from the operation of representatives from
two opsin gene families (SWS1 and LWS in marsupial and eutherian mammals; SWS2 and …

Dragonflies are colorful and large-eyed animals strongly dependent on color vision. Here
we report an extraordinary large number of opsin genes in dragonflies and their …

Twenty years ago, Dominy and colleagues published “The sensory ecology of primate food
perception,” an impactful review that brought new perspectives to understanding primate …

Primates have traditionally been regarded as vision-oriented animals with low olfactory
ability, though this “microsmatic primates” view has been challenged recently. To clarify …

Although variation in the color of light in terrestrial diurnal and twilight environments has
been well documented, relatively little work has examined the color of light in nocturnal …

Animals and fruiting plants are involved in a complex set of interactions, with animals relying
on fruiting trees as food resources and fruiting trees relying on animals for seed dispersal …

Retinal opsin photopigments initiate mammalian vision when stimulated by light. Most
mammals possess a short wavelength-sensitive opsin 1 (SWS1) pigment that is primarily …

Diurnal haplorhines exhibit derived traits for high-acuity photopic vision, unique across
mammals, and many other vertebrates. Yet, sometime in the mid-Miocene (12–15 MYA), the …

Although loss of short-wavelength-sensitive (SWS) cones and dichromatic color vision in
mammals has traditionally been linked to a nocturnal lifestyle, recent studies have identified …
