Hasanuddin University (UNHAS) showcased its research on aquatic biodiversity at the University of Antwerp, Belgium, on Thursday, 15 October 2026. Prof. Dr. Ir. Nadiarti, M.Sc., Vice Dean for Academic and Student Affairs at the UNHAS Graduate School, delivered a scientific presentation on fish biodiversity research using environmental DNA (eDNA) in the Lake Matano catchment area, South Sulawesi, to students and faculty members of the university’s Department of Biology.
As Chair of the Thematic Research Group on Aquatic Macrofaunal Biodiversity and Conservation (TRG AMBioC), Prof. Nadiarti introduced the group’s research activities, which focus on biodiversity and conservation in freshwater and marine ecosystems. She highlighted the integration of ecological, taxonomic, and molecular approaches to understanding aquatic organisms, their distribution, and the environmental pressures affecting their populations.
The presentation examined fish biodiversity across several sampling stations within the Lake Matano catchment area, including variations in fish community composition and the application of molecular techniques in biodiversity research. Prof. Nadiarti explained how eDNA analysis enables researchers to detect organisms through genetic material found in environmental samples, providing a complementary approach to conventional biodiversity surveys and species identification.
The session sparked discussions on ecological factors influencing species distribution and the importance of community involvement in biodiversity monitoring. “The discussion developed through participants’ questions about ecological factors affecting species distribution and how to involve local communities in aquatic biodiversity research and monitoring. I was pleased that the discussion covered both scientific aspects and community engagement, which are essential for connecting research with conservation efforts,” Prof. Nadiarti said.
Beyond sharing scientific findings, the academic exchange offered opportunities to strengthen research connections between UNHAS and the University of Antwerp, particularly through joint research, scientific publications, and postgraduate student engagement. “As Chair of TRG AMBioC and Vice Dean for Academic and Student Affairs at the UNHAS Graduate School, I hope this knowledge exchange will strengthen research collaboration and open opportunities for postgraduate students to participate in international research networks,” she added.
Through this international engagement, UNHAS continues to expand the global visibility of its research on Sulawesi’s aquatic ecosystems while exploring opportunities for cross-border scientific collaboration. The exchange is expected to support future research partnerships, strengthen postgraduate research capacity, and advance biodiversity conservation through international academic cooperation.
