- Abstract
We evaluated patterns of site preference for oviposition in Espadarana andina based on the identification and characterization of microhabitats during rainy and dry seasons. We also evaluated the presence of males and females at oviposition sites and the proximity of the adults to the clutches. An electivity index was used to determine which microhabitats were selected for oviposition and calling by males. Additionally, abiotic factors that might influence the oviposition site preference in this species were evaluated. Espadarana andina selected green leaves of Hedychium coronarium along the stream edge, at a height of 70-140 cm for both oviposition and calling sites. All the recorded clutches were found exclusively on leaves of H. coronarium, an invasive plant, suggesting that this plant offers advantages for the reproductive activity of E. andina over other plant species present along the stream border. There was no difference in site selection for calling, mating, and oviposition between dry and rainy seasons and among months. Males stood near clutches during the night, calling from the same plant. Although they were significantly closer to the clutches than females, they did not show any action to increase the survival of the embryos in the clutches. Therefore, we did not observe true egg attendance in E. andina; this observation fits with the absence of parental care behaviors described for the Centroleninae.
