Get to know the Gilt Darter complex! Katrina and Guy are joined by two guests from Yale University's Department of Ecology and Evolutionary Biology: Tom Near and Julia Wood. They imagine sitting down with the five species (Gilt, Masquerade, Brassy, Western Gilt, and Russet Darters) over dinner to understand the identity of each fish and how they're doing, dig into what makes a species a species, the definition of a species complex, and how the advancement of biodiversity discovery is important to conservation.
