Water turbidity-induced alterations in coloration and courtship behavior of male guppies (Poecilia reticulata)
(Springer, 2021-04-21)
Water turbidity deteriorates visibility and thereby may change the physiology and behavior of aquatic animals that rely on vision. In the guppy fish (Poecilia reticulata), a key element in the mating behavior and reproductive ...
How the observed color of the Swallow Tanager (Tersina viridis) changes with viewing geometry
(Elsevier Gmbh, 2019-04)
Non-iridescent coloration in birds’ plumage is associated with the quasi-ordered nanostructures of short-range order present within the feather barbs. Even though this type of color does not change with the observation ...
