SUMMARY:

Color patterns observed in nature are affected by biotic and abiotic factors. Latitude is an abiotic component that can influence animal coloration, as in butterflies. Dark colors (low brightness) retain more heat, while bright colors dissipate more heat, which directly relates to advantages in thermoregulation. There are two laws proposed to evaluate the color pattern resulting from biogeographic gradients. Bogert's law predicts that at high latitudes, organisms should be darker, while Gloger's law predicts that at low latitudes, organisms should be darker. The aim of this project is to evaluate if latitude and temperature influences butterfly coloration distributed throughout Brazil. For this purpose, using a photographic camera and a spectrophotometer, we will record the coloration of 72 species of butterflies from entomological collections. We will use multiple linear regressions to find if the latitude variables influence the coloration of Brazilian butterflies. The butterflies coloration is expected to follow the pattern expected by Gloger's law or Borgert's law.
