Q
What are the barriers to herbivory?
A
- Bottom up Control of plants
- Top down-control of herbivores by predators
- Herbivore populations cannot track plant resource abundance
2
Q
What is the class described example of plant control of herbivory?
A
Milkweed
3
Q
What plant configurations distribute VOCs more effectively?
A
Herbivory rates drop if plants are clustered
4
Q
What is a second role of plant VOCs?
A
They can produce VOCs that will bring predators that specialize on hunting certain herbivores
5
Q
What is mast seeding?
A
The synchronous production of seeds at very variable levels by a population of plants.
6
Q
What is a mast year or event?
A
A mast seeding event/year is a relatively very high seed production event.
7
Q
What is the point of mast seeding?
A
It is good for the prevention of growth of herbivores through constant growth or immigration with available resources
