Hypothesis
How do different light conditions affect the pre-adult fitness of two species of ants?
Conclusion
Exposure to light enhances pre-adult fitness in two dark-dwelling species of Camponotus by speeding-up development and by enhancing viability.
Supporting Evidence
- Ants develop fastest under constant light conditions.
- Pre-adult viability is higher under light conditions compared to darkness.
- Clutch size is reduced in one species under constant light.
Takeaway
Ants grow faster and have more babies when they get light, compared to when they are kept in the dark.
Methodology
The study involved introducing mated queens of two ant species into different light/dark regimes and measuring their development time and egg viability.
Limitations
The study focused only on the first batch of eggs and did not explore long-term effects of light exposure.
Participant Demographics
Two species of dark-dwelling ants: Camponotus compressus (night active) and Camponotus paria (day active).
