Primate color vision is based on two to three cone types in the retina, each expressing a
different class of visual pigment, making them the only mammals that possess trichromacy …

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

Background Long-term research of known individuals is critical for understanding the
demographic and evolutionary processes that influence natural populations. Current …

Intraspecific color vision variation is prevalent among nearly all diurnal monkeys in the
neotropics and is seemingly a textbook case of balancing selection acting to maintain …

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 …

Some primate populations include both trichromatic and dichromatic (red–green colour
blind) individuals due to allelic variation at the X-linked opsin locus. This polymorphic …

In some primate lineages, polymorphisms in the X-linked M/LWS opsin gene have produced
intraspecific variation in color vision. In these species, heterozygous females exhibit …

Abstract The lemurs of Madagascar (Primates: Lemuriformes) are a monophyletic group that
has lived in isolation from other primates for about 50 million years. Lemurs have diversified …

Vertebrate color vision is an ideal system for studying the gains and losses of genetic
variation across lineages and impacts on behavior. Among placental mammals, trichromatic …

The gut microbiome is a plastic phenotype; gut microbial composition is highly variable
across an individual host's lifetime and between host social groups, and this variation has …
