Acuity, the fineness with which sensory systems perceive and parse information, limits the
information that organisms can extract from stimuli. Here, we focus on visual acuity (the …

To understand the function of colour signals in nature, we require robust quantitative
analytical frameworks to enable us to estimate how animal and plant colour patterns appear …

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

Heliconius butterflies are well-known for their colourful wing patterns, which advertise
distastefulness to potential predators and are used during mate choice. However, the …

The giant panda (Ailuropoda melanoleuca) is an iconic mammal, but the function of its black-
and-white coloration is mysterious. Using photographs of giant pandas taken in the wild and …

More than 100 years ago, the biologist Jakob von Uexküll suggested that, because sensory
systems are diverse, animals likely inhabit different sensory worlds (umwelten) than we do …

Eyes have the flexibility to evolve to meet the ecological demands of their users. Relative to
camera-type eyes, the fundamental limits of optical diffraction in arthropod compound eyes …

Animal coloration patterns, from zebra stripes to bird egg speckles, are remarkably varied.
With research on the perception, function, and evolution of animal patterns growing rapidly …

Substantial progress has been made in the past 15 years regarding how prey use a variety
of visual camouflage types to exploit both predator visual processing and cognition …

Visual information affects animal behaviour and fitness in diverse ways, but a lack of suitable
methods to quantify visibility in three‐dimensional (3D) environments limits applications of …
