| Sumario: | Coloring is responsible in organisms for mediating the relationship between the individual and the environment in which they are inserted in important ways, including social signaling, antipredation defense, parasitism, thermoregulation, protection against sunlight at light wavelengths in the environment. ultraviolet range, microbes and abrasion. To this end, several factors are associated with color production in animals and, in addition, many factors are also associated with the perception of coloration expressed in animal bodies. Many factors can influence how colors are expressed, either individually, such as parasitism, or evolutionarily, as predation pressures. Thus, this paper aims to physically describe the coloration expressed on the Artibeus planirostris coat and to know if parasite infestation and predation pressure visually influence the way this coloration is expressed. For this, the colorings of A. planirostris in six body parts of different individuals were measured, aiming to use the color obtained to visually model how individuals at different moments of the life history of the species see each other and compare how they were seen by the predator and the co-specific. In addition, the influence of parasite infestation was tested to determine if there was a change in the expression of coat color. Our results showed that A. planirostris coat was better visually distinguished from foliage better by predator than by co-specific and that different aspects of species biology are distinguished by co-specific. We also show that parasite infestation influences the coloration expressed on the animals' coat, and is also distinctly visualized by other individuals between parasitized and nonparasitized animals. Our work is pioneering information about the coloration of bats and especially about how these animals see themselves and what are the relationships between this parameter and interactions with predators, as well as the influence of parasitosis on coloration expressed in the coat of animals. |
