River history
The study connects this distribution with past links between the Bonneville basin and upper Snake River. Compared with the smaller headwater-oriented Pantosteus platyrhynchus, green sucker tends to use larger, farther-downstream river reaches. Its historical type locality was considered mislabeled, another reason older names and locations need care.
Conservation significance
The researchers described substantial losses from former habitats and genetic mixing with related suckers in the upper Snake system. They emphasized Weber and Bear river populations as particularly important because these retained the species’ identity without the same evidence of mixing. Those conclusions describe the populations examined in that study rather than a current basin-wide census.
