function is still unclear. Phylogeny Data show that H. flischmann originated in North and South America. Comprise sister species Hyalinobatrachium tatayoi and individuals from Colombia, Ecuador, and Panama in the first clade; individuals from Costa Rica, Nicaragua, and eastern Honduras make up the second clade. The first two clades have no obvious structure, but the third clade, which includes individuals from western Honduras, Guatemala, and Mexico, showed a deep population structure. Known geographic regions indicated their effectiveness in differentiating H. flischmanni into three apparently isolated clades by working as a barrier to dispersal. Sea level and climate oscillations during the Pleistocene also had a strong influence on the structure and population of the glass frog clade. Interactions with humans and livestock Artificial affections on environmental interventions may promote the growth of algae and bacteria in streams. H. fleischmanni larvae readily feed on this resource. Moreover, natural or anthropogenic environmental noise can mask the acoustic signals produced by animals. A large part of the colony of the glass frog Hyalinobatrachium flischmanni (Centrolenidae) overlaps with noisy urban areas, which affects the species' acoustic communication. By studying the relationship between changes in anthropogenic noise levels throughout the night in areas of different noise level and the diurnal acoustic variations of acoustic activity within sites of H. flischmanni, the noise level and the acoustic activity of H. flischmanni varied throughout the night. The acoustic activity of H. flischmanni was found to be different in noisy sites than in sites with lower noise levels. The highest acoustic activity was found at the less noisy sites throughout the sampling period.
