Hypothesis
How is the immune system of collected bumblebees affected along the urbanization gradient?
Conclusion
Bumblebees in urban areas show increased expression of immune genes, indicating a shift in their immunometabolism due to urban stress.
Supporting Evidence
- Urbanization leads to increased immune gene expression in bumblebees.
- Pathogen prevalence was not significantly correlated with urbanization levels.
- Bumblebees in urban areas showed a metabolic shift towards immune activation.
Takeaway
Bumblebees living in cities are stressed and their immune systems are working harder, which might not be good for them.
Methodology
Bumblebees were collected along an urbanization gradient, and their immune gene expression was measured in relation to local environmental pressures.
Limitations
The study did not find clear correlations between urbanization and local air quality or pathogen loads.
Participant Demographics
Bumblebee species studied: Bombus lapidarius.
