The objective of this study was to investigate the abundance of marsh deer in the Paraná River Basin, above the Sergio Motta (Porto Primavera) Dam, before and after the impact of the dam closure. A fixed-wing, flat window aircraft was used to survey study transects. Observations were recorded based on the distance sampling line transect method, assuming that the detection probability decreases with increased distance.  aAbundance  aAnthropogenic impact  aCervids  aDistance sampling  aDistribution1 aPIOVEZAN, U.1 aCOSTA, M.
