We’ve spent some time on this podcast discussing pollinators and their life histories but today we are taking a deeper dive into plant chemistry to better understand the relationship between pollinators and their floral resources.

To help us explore this fascinating topic, is Leif Richardson, Xerces Endangered Species Conservation Biologist. Leif coordinates the California Bumble Bee Atlas project. His research focuses on the ecology, distribution, and declines of North American bumble bees. Leif is also the co-author of a range of scientific publications on bees, including Bumble Bees of North America: An Identification Guide. He holds a Master’s degree from the University of Arizona and a PhD from Dartmouth College.

CrimeLess: Hillbilly Heist

CrimeLess: Hillbilly Heist

It’s 1996 in rural North Carolina, and an oddball crew makes history when they pull off America’s third largest cash heist. But it’s all downhill from there. Join host Johnny Knoxville as he unspools a wild and woolly tale about a group of regular ‘ol folks who risked it all for a chance at a better life. CrimeLess: Hillbilly Heist answers the question: what would you do with 17.3 million dollars? The answer includes diamond rings, mansions, velvet Elvis paintings, plus a run for the border, murder-for-hire-plots, and FBI busts.
