The Federal University of Pará (UFPA) took part in the 7th Latin American Congress on Macroinvertebrates and Aquatic Ecosystems, held from August 25 to 29, 2025, at the University of Caldas in Manizales, Colombia. The event brought together experts from across Latin America to discuss progress and challenges in the monitoring and conservation of aquatic biodiversity.

​

The series of studies presented by UFPA researchers focused on understanding how human activities alter the distribution of Amazonian aquatic biodiversity and how to mitigate these impacts. Funded by the Brazil–Norway Biodiversity Research Consortium (BRC), the studies showcased findings on how bauxite mining, deforestation, and land use affect the diversity of insects, fish, and macrophytes in Amazonian streams. The analyses emphasize the identification of environmental thresholds that may lead to the replacement of more sensitive species by more tolerant ones, thus enhancing scientific understanding of the pressures on aquatic ecosystems—particularly in the context of international cooperation.

​

“International cooperation and partnerships between industry and academia are essential to transform scientific knowledge into practices that reconcile conservation and sustainable development,” said Professor Leandro Juen. Professor Thaísa Michelan added, “By integrating research across different biological groups and spatial scales, the BRC Consortium strengthens our ability to propose solutions to reduce environmental impacts and conserve Amazonian aquatic biodiversity.”

The research also highlighted the importance of forest cover and riparian vegetation in maintaining the richness of aquatic plants, while the reproductive behavior of dragonflies emerged as a valuable indicator of environmental integrity. In addition, the studies presented data on the effects of industrial pressures, which reduce the abundance of sensitive aquatic organisms and compromise key ecological processes—reinforcing the urgency of conservation and restoration efforts.
