Oyster Breeding, Climate Communication, Hellbender Vs Mantis Shrimp. Sept 10, 2021, Part 2
To Breed An Oyster
In the ocean, climate change involves more than just warming temperatures. Water levels are shifting, and ocean chemistry is changing. Changes to ocean salinity caused by shifting amounts of freshwater could have big effects on the health of oysters, who need a certain range of saltiness in the water to be happy.
As part of her doctoral work at Louisiana State University, researcher Joanna Griffiths bred hundreds of families of oysters, looking for clues to what makes an oyster more able to endure salinity changes. She found that there is a genetic component to an oyster’s salinity resilience.
Griffiths joins Scifri’s Charles Bergquist to talk about the work, and the challenges of conducting a laboratory oyster breeding program—in which it’s difficult convince an oyster that it’s time for romance, and often even hard to discern the sex of the oysters involved.
Talking Through The Tangled Terms Of Climate Change
When scientists talk about climate change, there are certain words and phrases that get brought up often. Terms like “mitigation,” “carbon neutral” and “tipping point” are used frequently to explain how the climate crisis is unfolding. They’re often found in reports meant to educate the public on climate change, such as the latest report from the UN’s Intergovernmental Panel on Climate Change.
It turns out a lot of words and phrases that scientists use to talk about climate change are not understood by the general public. That’s according to a recent study from the University of Southern California and the United Nations Foundation. This begs the question: if the public scientists are trying to reach don’t understand what’s being discussed, what’s the point?
Joining Ira to talk about better communicating climate change is Wändi Bruine de Bruin, lead author of the study and provost professor of public policy, psychology and behavioral science at the University of Southern California in Los Angeles, California. Also joining Ira is Anthony Leiserowitz, founder and director of the Yale Program on Climate Change Communication in New Haven, Connecticut.
An Aquatic Charismatic Creature Showdown: Mantis Shrimp vs. Hellbender
It’s time to kick off SciFri’s Charismatic Creature Carnival! Welcome to our celebration of creatures that are overlooked or unfairly maligned by the general public, which, if you look a little closer, have an undeniable charm. Six audience-suggested creatures were chosen, but only one will be crowned the very first carnival inductee into the Charismatic Creature Corner Hall of Fame.
The first friendly head-to-head battle in this fall’s Charismatic Creature Carnival is between the mantis shrimp and the hellbender, a giant aquatic salamander. Defending the mantis shrimp is Jason Dinh, PhD candidate in biology at Duke University in Durham, North Carolina. And representing the hellbender is Lauren Diaz, PhD student in fisheries science at Oregon State University in Corvallis, Oregon. Find a list of upcoming carnival celebrations below!
