Episode 240: Turtle Treks - Shells of the North

While connecting with fisher researchers Angela and Brandon were told over and over that there was one researcher they had to talk to. Dr. Roger Powell, Professor Emeritus at NC State University in North Carolina has been researching fishers for decades and is considered the expert on them. He shares his insights into fishers, how he raised fishers to learn more about them, and how they fit into, what he calls, a fitness landscape. 

Dr. Michael Joyce of the Natural Resources Research Institute (NRRI) at the University of Minnesota joins us to talk about why NRRI is researching fishers as they move from the north woods to southern Minnesota. What are the risks and rewards for a fisher living in a Three Rivers Park? How is he studying fishers? How can you help his research? Wander with us to find out. 

Fishers have been moving from northern Minnesota south and can now be seen in the Twin Cities area. What is a fisher? Join Brandon and Angela as they discuss what makes this large member of the weasel family special, and the special adaptations it has to help it hunt foods from rabbits to porcupines. 

Why does a scientist want poop mailed to them? Find out as Dr. Dr. Michelle Power joins us all the way from Australia! She has a passion for engaging the public in scientific research using it to help study diseases. We discuss what One Health is and how that impacts wildlife and human health. She also gives advice on what you can do to prevent antibiotic resistance and diseases in animals. 

Have you ever seen a sick fish? Dr. Isaiah E Tolo, Fish Health Supervisor at the Minnesota DNR, discusses diseases that affect fish, how he monitors for them, and what, if any, impacts they have on us. Learn how to help keep fish healthy as we dive deep into fish diseases.   

Just like humans, animals can get sick too. We wander with Dr. Michelle Carstensen, Wildlife Health Program Supervisor for the Minnesota DNR. How do animals get sick? What are some of the diseases the Minnesota DNR is looking out for in wildlife and how do they monitor for them? How can you help keep animals from getting sick? Wander with us to find the answers. 

Starting their research right here at Three Rivers, Dr. Jeanine Refsnider, shares the journey of being curious about Minnesota's State Threatened, Blanding's turtle, led to having her own lab at University of Toledo.  Jeanine shares past and current studies exploring turtle adaptions.   

How do baby turtles manage to wander from their nest to a lake or pond? If turtles are male or female is decided by temperature how will climate change impact them? Do turtle hatchlings coordinate their calendars to leave the nest? Learn all of this and more as Dr. Steve Freedberg, Professor of Biology at St. Olaf College discusses his research on turtles.  

Listen as Brandon and Angela start local with guest Dr. Tricia Markle from the MN Zoo to explore turtle species of the north, research, and conservation efforts we can all take towards healthy turtle populations such as road crossings.   

One of thing neonicotinoids are good at is traveling from where they are applied, to new areas by water. This is because it is designed to dissolve in water so seeds can suck it up. The unintended consequence is that it is effectively perpetually in rivers, streams, and other water bodies. Dr. Bill Arnold from the University of Minnesota about how and why he researches neonicotinoid presence in fresh water.
