SUMMARY Recent studies have shown that certain nocturnal insect and vertebrate species true color vision under illumination. Thus, their is potentially affected by changes in the spectral quality of twilight illumination, due to presence or absence moon,artificial light pollution other factors. We investigated this following manner. First we measured irradiance (from 300 700 nm) during day, sunset, twilight, full moon, new high levels pollution. The spectra were then converted both...
Determining how animals orient themselves using Earth’s magnetic field can be even more difficult than finding a needle in haystack. It is like stack of needles.
Visual acuity (the ability to resolve spatial detail) is highly variable across fishes. However, little known about the evolutionary pressures underlying this variation. We reviewed published literature create an database for 159 species of ray-finned fishes (Actinopterygii). Within a subset those which we had phylogenetic information and anatomically-measured data (n=81), examined relationships between both morphological (eye size body size) ecological (light level, water turbidity, habitat...
One classic explanation for the remarkable diversity of flower colors across angiosperms involves evolutionary shifts among different types pollinators with color preferences. However, pollinator shift model fails to account many examples variation within clades that share same pollination system. An alternate is competition model, which suggests divergence evolves in response interspecific pollinators, as a means decrease movements. This predicts overdispersion communities relative null...
In studies of animal orientation, data are often represented as directions that can be analyzed using circular statistical methods. Although several tests exist to detect the presence a mean direction, likelihood-based approaches may offer advantages in hypothesis testing - especially when multimodal. Unfortunately, inference orientation remains rare. Here, we discuss some assumptions and limitations common report new R package called CircMLE implement maximum likelihood analysis data. We...
There are dramatic and physiologically relevant changes in both skylight color intensity during evening twilight as the pathlength of direct sunlight through atmosphere increases, ozone increasingly absorbs long wavelengths becomes blue shifted. The moon is above horizon at sunset waxing phase lunar cycle, on night full below waning phase. Moonlight red shifted compared with daylight, so presence, position sky could modulate shifts twilight. Therefore, influence likely to differ somewhat...
