Resumo
The extensive damming of rivers around the world, regardless their economic purpose,
has changed the river landscapes and led to serious ecological consequences for the
biological organisms associated with these ecosystems. In the present study, a scientometric
analysis was performed aiming to assess temporal trends of the scientific production
related to environmental concerns about the impact of large dams on biodiversity
worldwide. On this context, a bibliographic review of the scientific works of this area, using
the research platform “Web of Science” searching for the keywords “dam impact” or “dam
effect” and “bio*diversity” in the subject line. The results showed that, despite the publication
number increase in the field, these studies are clearly more abundant in temperate
regions, which have less biological diversity. Although much of the planned hydroelectric
expansion is expected to occur in the tropics, which have most of the world’s biodiversity,
the biological knowledge about the species in these places is still very little. The lack of
studies in these areas may mask the impact intensity and extent of dams on biodiversity
and also induce decision-makers to adopt inefficient management strategies.
