PolliNation Podcast

In this episode of Pollination, host Dr. Andony Melathopoulos talks with Dr. Elizabeth Murray ( Mt. James Entomological Collection, Washington State University) about pollen wasps (Masarinae) and how they represent a rare, parallel shift to bees from carnivory to provisioning young with pollen. The conversation covers pollen wasp origins around 125 million years ago alongside bees, likely in arid Western Gondwana as angiosperms rose, their global but dry-region-biased distribution, low species diversity ( 00:00 Gondwana Origins Teaser 00:58 Podcast Intro And Guest 02:22 Inside The Entomology Collection 03:49 Why Collections Matter 05:27 Growing The Collection 06:52 What Are Pollen Wasps 09:04 Angiosperms And Shared Origins 11:00 Reverting Back To Carnivory 12:40 Where They Live And Diversity 15:49 Life History Compared To Bees 18:07 How They Carry And Pollinate 19:21 Nests And Plant Hosts 23:31 Research And Conservation Questions

Christine McDonald discusses her family-run beekeeping operation based in Terrace, British Columbia. Living in a remote area, Christine emphasizes the importance of in-person gatherings for bee education despite the proliferation of online resources. She explains how her family has turned geographical challenges into strengths, mentioning their diverse range of products, including honey and candles, and their reliance on wild forage like fireweed. Christine highlights the seasonal challenges they face, such as preparing colonies for winter and managing a short beekeeping season. She also elaborates on their approach to raising queens and maintaining their operation's sustainability. Additionally, Christine's Instagram presence has become a pivotal part of connecting with the wider beekeeping community.

This week, we talk with Ryan Lieuallen of Sweet Bee Honey Company in Milton-Freewater, Oregon. Ryan shares insights into the significant challenges and changes within the beekeeping industry, including high winter mortality rates and the potential economic impacts of the Tropi mite infestation. We discuss the emergence of new Varroa treatments and innovative strategies for creating sustainable bee pastures for bees. Explore Ryan's dedication to maintaining a five-generation beekeeping heritage while adapting to future challenges in beekeeping and sustainable agriculture.

In this episode of the podcast, Dr. Zach Portman discusses a new paper addressing the problem of ghost records in bee data. These records often lack physical specimens, creating challenges for verifying data of bee species. Dr. Portman explains the process and complications behind collecting and verifying bee data, emphasizing the importance of preserving specimens. The conversation also delves into the implications of ghost records for conservation efforts and taxonomy, proposing that funding agencies should require proper storage plans for collected specimens.

Pollinator Pathway is a national organization dedicated to the establishment of native plant communities for pollinators that are managed without pesticides. It got started in the Western US in Bend, Oregon and this week we hear from two board members, Gwen Bartonek and Lisa Sanco, about the many activities the organization has pulled off in Oregon's High Desert city.

In this episode of the Commercial Beekeeping Zone on PolliNation, we hear from Curtis Miedema, a second generation beekeeper from Barhead, Alberta, and President of North America's only beekeeper's commission. Curtis shares insights into stationary beekeeping and how he fits queen production into an operation focused on honey production. He also discusses the collaborative nature of the Alberta beekeeping community and the role of the Alberta Beekeepers Commission. Links: https://miedemahoney.com https://www.albertabeekeepers.ca

We hear from Lincoln Best and August Jackson from Oregon State University this week about an initiative to inventory the bees of National Wildlife Refuges in Region 1 by Master Melittologist volunteers. Link to year 1 report: https://ir.library.oregonstate.edu/concern/technical_reports/xd07h2826

The attention to California almonds, means the pollination of Washington State tree fruits is often overlooked. But the massive pollination effort in Washington is a huge effort and may be facing potential problems. Harry and Andony catch up with commercial beekeeper Tim Hiatt to discuss tree fruit pollination, as well as Tim's efforts to advocate for beekeeping in the Washington legislature.

This week on PolliNation Itai Kanot and Shelbi Perkins from BeeHero discuss how their in-hive and in-field sensors are improving pollination efficiency by providing real-time data on bee colony strength, benefiting both growers and beekeepers. BeeHero: https://www.beehero.io/

Dr. Diana Cox-Foster joins us to discuss her and her team's research at the USDA on honeybee and native bee competition. From lab tests to field studies, they uncover the effects of this competition on pollination.
