The Amazon has a great amphibian richness species and have been decimated by the destruction of their habitats due to the construction of roads, which generates an edge effect on their populations and subsequent local extinction. The study was made from may ton august 2023 with main objective of this work was to evaluate some ecological impacts of the Zungarococha highway on the population density of Ranitomeya reticulata (Anura: Dendrobatidae) department of Loreto, Peru. A sampling design using visual encounter survey was carried out from the edge of the road to 310 m. within the forest, which consisted of 10 plots of 30 x 30 m in the forests of the Center for Forestry Research and Education-CIEFOR. Data on the abundance of the species and the number of trees and the environmental variables of relative humidity (%) and temperature (°C) were obtained within each plot. Regression analysi...
