Descrição: dc.descriptionThe liver is an important metabolic organ in vertebrates. In anurans, the hepatosomatic index (HSI) reflects differences in energy storage and reproductive activities between males and females. The objective of this study was to describe the histological and histometric parameters of the livers of five species of Neotropical anurans, taking sex-related differences into account. We also tested how the relationship between quantitative histometric variables and HSI varied between males and females in different species. Five males and five females of Elachistocleis matogrosso, Leptodactylus podicipinus, Lysapsus limellum, Pseudis platensis, and Trachycephalus typhonius were captured in central Brazil during the rainy season. HSI did not vary according to sex, but it varied among species. Elachistocleis matogrosso had the highest HSI due to the large hepatocyte size. The percentage of melanomacrophage centers (MMCs) was higher in P. platensis and L. limellum. In T. thyphonius, hepatocyte area was negatively associated with HSI, while the MMC percentages were positively associated with HSI. The liver plays a key role in reproductive activities, especially for species with explosive reproduction. Additionally, histometric patterns and volumetric structural density varied between males and females due to energy utilization for reproduction. Not only are these results important for future studies on hepatic morphophysiology but they also provide tools for evolutionary and phylogenetic studies.-
