Dr Romina Henriques, a passionate marine biologist and senior lecturer at the University of Pretoria (UP), has been awarded a C2 rating for her research by the National Research Foundation (NRF). The rating recognises her significant contributions to marine biology and the study of the evolution of marine species.

“Receiving a C2 NRF rating is a rewarding recognition of the research I've been engaged in for over a decade,” Henriques says. “This process allowed me to identify areas that I need to develop in the next five to ten years.”

Dr Henriques' research on the unique marine fish populations of Southern Africa is fuelled by the knowledge that climate change threatens to alter ocean temperatures, current patterns and salinity levels, which is affecting the survivability of marine species. “These species have an intrinsic value; they exist on this planet and have the right to continue existing,” she says. 

“Southern Africa is a natural laboratory for studying evolution in marine species because of its unique oceanic conditions,” Henriques explains. “The warm Agulhas current off the east coast and cold Benguela current off the west coast create distinct environments that influence how these fishes evolve. Understanding these patterns is essential for their conservation and sustainable management.”

Henriques’ research leverages advanced genomic tools to study fish populations in these distinct marine environments. By analysing fish DNA, she investigates how many populations exist, their geographical distribution, level of diversity, and connectivity patterns. This information is crucial for understanding how these species might adapt to changing ocean conditions.

The implications of this research extend beyond academic interest. Marine fisheries represent significant economic and recreational value, supporting numerous industries and livelihoods. Henriques’ work provides essential data to aid in developing effective conservation strategies and sustainable management practices for commercially exploited fish species.

Since joining UP in 2021, Henriques has built her reputation through both research and mentorship. “I want my legacy to be my students and the people I worked with,” she says. Her advice to aspiring scientists emphasises community: “Identify what really drives you, work towards it, and surround yourself with people that have your best interests at heart. You never work alone – you work within a community.”

Beyond the laboratory and genomic analysis, Henriques maintains her connection to nature through hiking and outdoor activities, reflecting the passion that initially drew her to marine biology.

As marine ecosystems face mounting pressures from climate change and overfishing, Henriques' work strengthens the foundation for evidence-based conservation strategies. Her research illuminates the complex relationships between marine species and their changing environment, contributing to the protection of Southern Africa’s rich marine biodiversity.
