Melanocytes are found in various organs of ectothermic animals, playing a protective role
against bacteria and free radicals. It is known that pigment cells from hematopoietic organs …

Amphibians are considered to be excellent bioindicators to their morphophysiological
characteristics and life cycle. In this context, the present study investigated the morphological …

Glyphosate (GLY) is the most used herbicide worldwide and its effects on anurans are well
known. Pollutants can cause physiological and morphological effects. Therefore, this study …

Fish and amphibians have pigment cells that generate colorful skins important for signaling,
