A team led by the Hong Kong University of Science and Technology (HKUST) has developed a technique to study how different fish species interact with each other in a coastal region, a breakthrough that helps explain the complex relationships among marine species and how global warming impacts fish populations.

By analyzing minute traces of fish DNA from samples of seawater, the team combined the use of environmental DNA – known as eDNA – and advanced statistical analysis to not only detect the presence of fish species, but also reveal how the species interact with each other. Read More...
