308 - Making Bee Habitat in Vineyards | PolliNation
PolliNation
Join us for a conversation with Shannon Mayhew, Stewardship Director and Biodynamic Estate Gardener at Brooks Wine. Shannon and the Brooks team were honored with the 2025 Oregon Bee Project Bee Steward Excellence Award for their outstanding commitment to pollinator health — from diverse flowering cover crops between vine rows to two acres of gardens designed to provide consistent forage for bees and other pollinators across the entire growing season. In this episode, we dig into what day-to-day stewardship looks like at a biodynamic winery, why pollinators matter to wine, and what...

307 - Are Bees Losing Their Way? How Odor Pollution Disrupts Pollination | PolliNation
PolliNation
Dr. Jordanna Sprayberry, Associate Professor & Director of Undergraduate Biology at Stony Brook University, joins the Pollination podcast to explain how agrochemical odors interfere with bees' ability to find flowers — and why that matters for entire ecosystems. Dr. Sprayberry is a pollination neuroethologist who studies how nervous systems process sensory information and how that processing drives foraging behavior. In this conversation, she breaks down her lab's groundbreaking "odor geometry" system for measuring olfactory pollution thresholds, shares findings from wind tunnel...

306 - SloBees (Bumble Bee Surveys in Slovenia with Dr. Danilo Bevk) | PolliNation
PolliNation
Slovenia — a country the size of New Jersey — is home to 575 bee species, more than a quarter of all species known in Europe. It's the birthplace of the Carniolan honeybee, but it's also a hotspot for wild and solitary bees. This week, we sit down with Dr. Danilo Bevk, a researcher at the National Institute of Biology in Ljubljana and founder of the SloBees Society (Čmrljica), to talk about Slovenia's remarkable pollinator diversity, a citizen science project tracking bumblebee queens across the country, and a new Europe-wide monitoring scheme about to transform how we track these...

305 - Inside the USGS/FWS Native Bee Lab: Building Bee Monitoring, ID, and Data Capacity | PolliNation
PolliNation
This week, we catch up with Sam Droege with the US Geological Survey and Clare Maffei with US Fish and Wildlife Service to discuss the origins and evolution of the Bee Lab and its role as a support hub for bee biodiversity work. Sam describes shifting from designing national monitoring programs for birds and other taxa to pollinators, finding bee monitoring statistically difficult due to high year-to-year variance and identification bottlenecks, and pivoting to developing sampling techniques, the Very Handy Bee Manual, Discover Life online ID guides, photography resources, and a large...

304 - Millions of Solitary Bees in a Cemetery: Andrena regularis Aggregations and Parasite Dynamics | PolliNation
PolliNation
Dr. Bryan Danforth of Cornell University joins the podcast to discuss a new Apidology study led by Steven Hodge on emergence dynamics and host–parasite associations in a massive cemetery nesting aggregation of the solitary bee Andrena regularis. Using emergence traps checked daily for 40 days at East Lawn Cemetery near Cornell, the team estimated a mean population size of 5.5 million emerging bees within a compact area and documented synchronized host emergence with more gradual, delayed emergence by Nomada cuckoo bees, plus low-frequency associates including a meloid beetle and a...

303 - Wonderful World of Wasps | PolliNation
PolliNation
Wasps are an often underappreciated and underdiscussed pollinator group. In today’s episode, we will dive into their fascinating world. We’ll define what exactly a wasp is, the diversity of wasps around the world, their specialized hunting skills, and far beyond. Sloan Tomlinson is a science communicator, insect photographer, and regulatory contributor to wasp educational programs.

302 - Forest Log Landings for Bees | PolliNation
PolliNation
Log landings serve as a unique way to provision habitat in otherwise closed-canopy forests, providing refuge for wild bees and wasps. UMass Amherst PhD candidate Aliza Fassler unpacks her research on seeding log landings with native plants, and speaks to the pollinator assemblages that use them. Learn more about Aliza’s research in this technical report: Visit the UMass Extension pollinator resources page: ag.umass.edu/pollinators

301 - Mason Bees 101: How to Care for Blue Orchard Bees (and Stop Houdini Flies) | PolliNation
PolliNation
Thyra Mckelvie joins PolliNation to discuss managing blue orchard bees (mason bees). Thyra is the Managing Director and Solitary Bee Educator at Rent Mason Bees. She outlines three essential care steps: start with clean, openable nesting material of proper size, remove nests at the end of spring to protect developing bees from summer predators, and harvest/clean cocoons in fall to control pests and disease. In addition, Thyra covers the key pests of mason bees include pollen mites, Houdini flies, chalkbrood fungus, and monodontomerus wasps, plus sterilization methods. Rent Mason Bees...

300 - PolliNation RELOADED | PolliNation
PolliNation
As the 300th episode approached Dr. Melathopoulos started to get nervous. He had been doing the show since 2018. When his podcasting hero Melvyn Bragg hung up his podcasting mic last year, Dr. Melathopoulos wondered if he should do the same. But no. Polli-Nation is officially outgrowing its borders! While the show's roots are at OSU Extension, we are thrilled to welcome a new collaborative hosting team. By bringing in the expertise of Nicole Bell (East Coast/UMass), and Drs. Brandon Hopkins and Priya Chakrabarti Basu (WSU), we are expanding our coverage from the wild bee meadows of New...

299 - Inside Idaho's Alfalfa Leafcutter Bee Cocoon Testing Center | PolliNation
PolliNation
In this episode Dr. Melathopoulos speaks with Dr. Armando Falcon-Brindis, assistant professor and extension specialist in entomology at the University of Idaho’s Parma Research and Extension Center and director of the Parma Cocoon Testing Center. Dr. Falcon-Brindis explains why alfalfa leafcutter bees are far more effective than honey bees at pollinating alfalfa seed and describes how the lab uses X-ray imaging to assess cocoon health by counting live larvae, dead cells, pollen balls, machine damage, predators, parasites, and signs of pathogens, with follow-up dissections when needed. He...
info_outlineIn 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.
