Stunning underwater images showcase the beauty of the Coral Sea in a new exhibition.

Before species go extinct, their populations often shrink and become isolated. Healthy populations tend to have a large gene pool with many genetic variants circulating. But the path to extinction erodes genetic diversity, because a species’ gene pool shrinks as the population declines. Losing genetic diversity limits the ability of populations to adapt to threats such as disease and climate change.
