73 Research Retinue – Is Glyphosate Harmful To Bees?

Posted on by | 2 Replies

Research Retinue on PolliNation with Andony Melathopoulos

The OSU Research Retinue goes into depth on research papers that have been recently featured in the news. We convened Retinue this week to review a paper that got a fair amount of press over the past few months. Glyphosate is the most widely used herbicides in the world and is regarded as relatively non-toxic to bees and other pollinating insects. A study by Erick Motta and his colleagues from the University of Hawaii at Manoa demonstrate an indirect link between glyphosate and honey bee health in a laboratory study, namely a link to bacteria found in honey bee guts that helps fend off diseases.
This week’s retinue consists of OSU undergraduates Addison DeBoer (Biochemistry and Molecular Biology), Lacey Jane (Zoology), Isabella Messer (Horticulture) and Umayyah Wright (Geography).

Learn more about the recent research studying the effects of glyphosate on honeybees, and how glyphosate can indirectly affect their gut homogenate.

“Those lactobacillus bacteria are supposed to not be sensitive to the glyphosate, so it’s weird that the single dose would affect them, but when there’s a double dose, there seems to be no change.” – Addison DeBoer

Show Notes:

  • What makes up the microbiome of a honeybee
  • How glyphosate works as an herbicide
  • Why glyphosate indirectly affects bees health
  • How the study was conducted
  • The two different kinds of significant bacteria found in the honeybee gut
  • What could have improved the study
  • How the timing and frequency of applying glyphosate affects honeybees
  • The different ways that science and news outlets are reporting this story

“The bees that had none of the gut homogenate and the bees that have the gut homogenate and glyphosate were affected almost exactly the same, which shows that the effect of glyphosate basically counteracts all of the positive effects of the gut homogenate.” – Addison DeBoer

52 OSU Research Retinue – Mowing or mowing less: What helps the bees more?

The OSU Research Retinue reviews a research study that garnered a fair amount of press this month on the connection between lawn mowing frequency and bee abundance and diversity. The study, led by Susannah Lerman from USDA Forest Service Northern Research Station, compared the bees visiting lawns mowed weekly, every two or three weeks. The two year study was published in the May issue of the journal Biological Conservation.

This week’s Research Retinue consisted of OSU undergraduates Addison DeBoer (Biochemistry and Molecular Biology), Matthew Bucy (Environmental Sciences) and Umayyah Wright (Environmental Sciences). Special thanks to Isabella Messer (Horticulture) who helped the group research the paper (check out Isabella’s bee blog entries).

“I feel the general public won’t have time to read this paper and it would be great to have a simple message summarizing the findings on social media”. – Umayyah Wright

“So, say you are approached by someone – walking on the street – and they heard about the article but have no time to read it what would you tell them the one important take away of this paper?” – Matthew Bucy

“Don’t go for more that three weeks without mowing your lawn because the grass will get too long for the bees, which almost the opposite of the final line of the paper of taking the “lazy lawnmower” approach.  But mowing once a week had more species richness and mowing twice a week had more bee abundance compared to mowing the lawn every three weeks”. – Addison DeBoer

Show Notes:

  • How the study was conducted and what was measured
  • What the study found was best for bee populations in lawn maintenance
  • What key elements are most important in increasing and maintaining pollinator health
  • How researchers can improve the study for next time, and what they got right
  • Why homeowners should consider changing their mowing habits to better suit pollinator health
  • Why this study is very important for busy homeowners
  • What people without lawns can do to help the local pollinator habitat
  • Which is more important: bee richness or bee abundance
  • What the Research Retinue would improve in the next study similar to this one

42 Research Retinue – Honey Bees and Conservation

Posted on by | 2 Replies

The Research Retinue is a new segment on PolliNation that goes into depth on research papers that have been recently featured in the news. The Retinue is made up of intrepid OSU undergraduates and this week involved Addison DeBoer (Biology), Lacy Haig (Zoology), Umayyah Wright (Environmental Science), Isabella Messer (Horticulture). They take up the question of the conservation implications of honey bees by examining two papers published in top research journals last month that take up this question from different angles.

Listen in to learn more about how honey bees affect global regions, which pollinators are the most effective, and how studies could improve their research.

“Even if [honey bees] could [do the job of all the other pollinators combined], would we want them to? Because then we’d be missing out on all of the ecological variation of the other species.“ – Umayyah Wright

Show Notes:

  • How the honey bee contributes to pollination of wild plant communities worldwide
  • Why honey bee contributions to wild plant pollination can change due to many different environmental factors
  • How effective a pollinator the honey bee is in comparison to other bees
  • Why a pollinator’s native region is so important in it’s local ecosystem
  • Why simply pollinating plants is not the entire goal of pollinator protection
  • What is the most important trait of pollinators for conservation
  • Why these studies were useful, and what they need to improve
  • What the Research Retinue would like to see in the future for pollinator studies
  • Are their risks associated with beekeeping in sensitive areas
  • How different programs are taking steps to help home gardeners benefit the pollinator population
  • What home gardeners can do to help local pollinators flourish

“In the fight for bee conservation, we shouldn’t be focusing on honey bees because that’s an agricultural and economic issue, not a conservation issue.” – Isabella Messer
