In nature hybrid zones are where two species or varieties meet and cross fertilize, such as the classic donkey plus horse equals mule. A single hybrid zone is scientifically important for understanding how species diverge. So imagine the excitement of finding not just one, but two hybrid zones in the Andes of South America. And even cooler the hybrid zone is the home of a special type of bird, flowerpiercers, who steal nectar from plants using their pirate-hooked bills. Anna Hiller, LSU Museum of Natural Science Ph.D. candidate, tells us what hybrid zones are, what we can learn from them and how she is using the flower piercers as her model. She also shares adventures from her previous expeditions and how her passion to include women in science is informing her upcoming field trips to Peru and Bolivia.LSU College of Science Geology & Geophysics professor, invites us to learn about the evolution of Antarctic ice sheets and how he investigates the movement of ice sheets and ice rises over geologic time to aid in predicting their future behavior.
