摘要

Eleutherodactylus bartonsmithi is a critically endangered Cuban frog with an extremely restricted range, found only in the evergreen forest surrounding the Yumurí River Canyon, Baracoa, Guantánamo. The region has undergone significant disturbances due to Hurricane Matthew and the construction of a 4.5 km road, yet the impact of these disturbances on the species remains unknown. This study provides the first data on the species’ occurrence, vocal activity, distribution, and relative abundance, using eco-acoustic methods to assess habitat health following these natural and anthropogenic disturbances. Over 15 days of semi-continuous acoustic recordings were collected in February, June, and October 2022 from five sites within the species’ type locality. Analysis of acoustic indices indicated that, despite the road’s impact, sites with greater soundscape complexity and heterogeneity were those closest to the road. These sites also showed the highest relative abundance of the species. The highest acoustic activity of E. bartonsmithi was detected in October, when environmental conditions appeared most favorable. Across all sampled months, peak daily activity occurred from 05:00 to 07:00 h, coinciding with the most intense male choruses. These findings provide essential baseline data for the development of conservation strategies aimed at protecting E. bartonsmithi and its habitat. Additionally, these efforts could benefit other endangered Cuban anurans in the region, such as E. bresslerae and E. etheridgei.
