Abstract

This article examines the impacts of the Santo Antônio Hydroelectric dam on the abundance, sex ratio, and reproductive phenology of phyllostomid bats in the southeastern Brazilian Amazon. Analyzing 3,298 captures across 49 species before and after dam construction, the study found that while females consistently outnumbered males, the dam reduced overall bat abundance—particularly during the rainy season—without altering sex ratios. Most species exhibited bimodal reproductive patterns, but dam operations delayed and shortened female pregnancy and lactation periods, likely due to resource loss from flooded vegetation. The authors emphasize the need for long-term monitoring to understand the consequences of these reproductive changes on bat population recovery in dam-affected landscapes.
