Bitter Nectar, Toxic Pollen: Pollinators and Plant Chemicals
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.---Photo credit: Barbara Driscoll (c)Thank you for listening!

Leave the Leaves or Lose the Insects
Leave the leaves has become something of a rallying cry and discussion topic in recent years. When the weather starts to cool and leaves begin to fall, we’re presented with a valuable wildlife and gardening resource — but also something of a headache. Do I keep them all? Can I mulch them? Won’t they kill my lawn? What about pests? How do I keep my HOA happy?Joining us to take a deeper dive into a pile of leaves, how they help insects, and how to manage them is Max Ferlauto, state entomologist with the Maryland Natural Heritage Program, where he is in charge of rare insect conservation. Before that, Max was undertaking research for his PhD at the University of Maryland, where he studied the impact of leaves (and leaf removal) on insects in gardens as well as on soil health.---Photo: Steven Severinghaus/Flickr/Creative Commons 2.0Thank you for listening!

Monarchs & Pesticides: Understanding the Impact, Exploring the Solutions
In this episode, we will be taking a closer look at the monarch butterfly, but we won’t be talking about milkweed or nectar plants, or the migration and overwintering sites – at least, not directly. No, our focus is on pesticides and monarchs. Are pesticides a particular concern for monarch butterflies? What are the consequences of pesticide contamination to their habitat? What can we do to provide pesticide-free habitat?To answer these questions we welcome back Emily May, Agricultural Conservation Lead with the Xerces Pesticide Reduction Program. Emily works with farmers, researchers, conservation professionals, and agencies across the U.S. to reduce pesticide risks to pollinators and other beneficial insects, support the adoption of ecologically sound pest-management practices, and expand high-quality habitat in working lands. She also supports Xerces’ staff by providing technical expertise that helps guide resources, outreach, and policy efforts.---Photo: Stephanie McKnight/Xerces SocietyThank you for listening!

Understanding Native Bee Populations: The State of the Bees Initiative
How are native bee species in the US doing in light of the major threats they are facing? What more do we need to know to protect them? There are over 3,600 species of native bees in the United States, but we only know the conservation status (i.e., how well they are doing) of about 20% of them. This makes it difficult to make decisions about how to prioritize bee conservation. Joining us to discuss this problem is Saff Killingsworth, Xerces Endangered Species Conservation Biologist. Saff coordinates the State of the Bees initiative, working with researchers and land managers to assess the status of wild bees in the western U.S. and address their conservation needs. She also works to advance conservation of butterflies and fireflies in Arizona. ---Photo: az3/Flickr CC BY-NC-SA 2.0Thank you for listening! For more information go to xerces.org/bugbanter.

The Living Fence: Hedgerows as Havens for Insects
Co-host Matthew Shepherd came from Britain, a country known for its hedgerows. He grew up surrounded by hedges, sometimes many centuries old, crisscrossing the countryside. Early in Matthew's career he helped plant, maintain, and restore miles of hedgerows and got to see up close the wealth of wildlife that live in them. When he moved to America, he was struck by the lack of hedgerows, their place in the landscape frequently filled by barbed wire or other types of fencing. He is very happy to know that this is changing and that there is a movement in this country toward planting hedgerows for their beauty, wildlife value, and economic benefits.Joining Matthew in this episode is someone who has been at the forefront of this effort for a decade and a half. Jessa Kay Cruz is a Senior Pollinator Conservation Specialist for the Xerces Society in a region covering California and the Intermountain West. Since joining Xerces in 2008, Jessa has worked in agricultural and natural lands to create habitat for pollinators and other beneficial insects, and to promote practices that support them. She provides education and technical support to a range of individuals and agencies, including farmers and ranchers, agricultural professionals, and land managers.---Cover Photo: Sarah Foltz Jordan/Xerces SocietyThank you for listening!
