David Dimitrie on behavioral interactions in frogs

David Dimitrie on behavioral interactions in frogs

In today’s episode, meet David Dimitrie, a PhD candidate in the Department of Biology at Case Western Reserve University. He is an amphibian ecologist, focusing on how amphibians respond to changes in the environment (although he has an equal love for anything reptile). David is also a science educator and has been teaching in both the formal and informal science classroom for over 10 years.

Learning about biological sounds:

Raven Sound Software is created and managed by the Cornell University Lab Center for Conservation Bioacoustics. They provide excellent resources and educational materials for learning about biological sounds. Student (K-12) and educator licenses are available to purchase for the Raven Pro software; however, the free Raven Lite software has excellent capabilities to view and conduct basic analyses on sound files.

Become a frog watcher:

To learn more about how you can become involved with citizen science efforts in the US to monitor frogs , check out FrogWatch. FrogWatch USA is a citizen science program that provides opportunities to learn about wetlands by reporting on the calls of local frogs in your community.

Get in touch with David:

David is eager and willing to share frog recordings from his research for classroom and research educational purposes. Please feel free to contact him (dad125@case.edu) if you would like to discuss methods to incorporate frog calls into your classroom or educational programs!

Viewing atoms with microscopes with Justin Ondry, PhD

Viewing atoms with microscopes with Justin Ondry, PhD

In this talk, Justin Ondry, PhD joins us to discuss how scientists are able to look at individual atoms using an electron microscope and how this has enabled breakthrough discoveries in physical and biological sciences. Justin received his PhD in Physical Chemistry in 2020 from the University of California, Berkeley. At Berkeley, Justin used transmission electron microscopy to study the structure and defects in semiconductor nanocrystals. He is currently the James Franck Postdoctoral fellow at the University of Chicago where he is studying molten salt synthesis of colloidal nanocrystals.

David Hill, PhD on citizen science and studying snow

David Hill, PhD on citizen science and studying snow

David Hill is a professor at Oregon State University and a National Geographic Explorer. No matter the hemisphere, if it is spring time, you’ll find him out on skis sampling the snow between mountain summit and trailhead. For over 25 years, he has studied how water behaves from snowy mountain headwaters to coastal environments. David joins us to talk about how we can use citizen science to study snow.

Snow science interactive map:

Check out this map of California and Nevada to learn details about recent snowmelt and more. David’s suggestions:

1. Play around with toggling on the ’swe data.’ You can show actual values, changes, percent of normal, and so on.

2. Play around with National Gridded Data. This is a computer model, at a coarse 1 km scale. With CSO, we try to run models on a 25 meter scale or so.
Engage in your own citizen science:

You can contribute to projects like David’s through sharing your own snow depth data. Check out Mountain Hub to get involved.

Kelly Loria on mountain stream health

Kelly is a PhD candidate in the Natural Resources and Environmental Science Program at the University of Nevada, Reno working with Dr. Joanna Blaszczak. Her background is in alpine lake ecology having led a team monitoring the alpine lakes in the Green Lakes Valley of Colorado. Her recent research interests include investigating patterns of metabolism and nutrient uptake by algal communities of mountain streams in Lake Tahoe Basin.
