Hypothesis
Do males experience more herbivory than hermaphrodites in Mercurialis annua due to their growth rates?
Conclusion
Males of Mercurialis annua, which grow more slowly, are more heavily eaten by snails than hermaphrodites, rejecting the faster-sex hypothesis.
Supporting Evidence
- Males were significantly more heavily eaten by snails than hermaphrodites.
- Hermaphrodites had more leaves and greater total above-ground biomass than males.
- The study tested the faster-sex hypothesis in an androdioecious species.
Takeaway
In this study, we found that male plants were eaten more by snails than female plants, even though the males grow slower.
Methodology
The study involved planting male and hermaphrodite plants in pots and exposing them to herbivory by snails, measuring the damage over time.
Participant Demographics
Plants were collected from an androdioecious population near Fes, Morocco.
