Studies on animal colour vision typically focus on the chromatic aspect of colour, which is
related to the spectral distribution, and disregard the achromatic aspect, which is related to …

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 …

Abstract Stingless bees (Apidae, Meliponini) are a group of highly eusocial bees with
pantropic distribution. The variety of life styles among the approximately 600 species and …

Many broadcast spawning corals in multiple reef regions release their gametes with
incredible temporal precision just once per year, using the lunar cycle to set the night of …

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 …

Background Rhabdomeric photoreceptors of eyes in the terrestrial slug Limax are the typical
invertebrate-type but unique in that three visual opsins (Gq-coupled rhodopsin, xenopsin …

Light environments differ dramatically between day and night. The transition between
diurnal and nocturnal visual ecology has happened repeatedly throughout evolution in …

For compass orientation many insects rely on the pattern of sky polarization, but some
species also exploit the sky chromatic contrast. Desert locusts, Schistocerca gregaria, detect …

Insects face the challenge of navigating to specific goals in both bright sun-lit and dim-lit
environments. Both diurnal and nocturnal insects use quite similar navigation strategies …
