Population genetic and phylogenetic analysis of pupfish (Cyprinodon, Cyprinodontidae) in the Rio Conchos and adjacent rivers reveals hidden diversity - Conservation Genetics Conservation Genetics - Understanding genetic and phylogenetic relationships among closely related species is critical for effective conservation planning. In the Rio Conchos basin of northern...

The Conchos pupfish is not a monolith! We found strong genetic divergence within Cyprinodon eximius, including the Devils River population in TX. Check out our new paper in Conservation Genetics! #fish #FishSci #TeamFish link.springer.com/article/10.1...

The Most Urgent Wildlife Issue Dear friends, Last week I mentioned that I have written a short book about the scientific findings on fish feeling pain. The question of whether fish feel pain appears simple, yet it has enormous cons...
