Hypothesis

How does exposure to black carbon particulates affect the gut microbiome of bumblebees?

Conclusion

Exposure to black carbon significantly alters the gut microbiome composition of bumblebees, increasing beneficial bacteria.

Supporting Evidence

  • Black carbon exposure increased the abundance of beneficial bacteria Bombilactobacillus in bumblebees.
  • Significant changes in gut microbiome composition were observed after black carbon treatment.
  • Bumblebees did not show significant differences in survival or activity levels after exposure.

Takeaway

Air pollution can change the tiny bugs living in bumblebees' tummies, which helps them stay healthy.

Methodology

Bumblebees were exposed to black carbon in their food, and their gut bacteria were analyzed before and after exposure.

Limitations

The study was conducted in controlled laboratory conditions, which may not fully represent natural environments.

Participant Demographics

Adult worker bumblebees (Bombus terrestris) aged 7 ± 1 days.
