A farmer adds a second crop species to a monoculture, but both crops are close relatives attacked by the same specialist beetle. Which prediction best explains why resilience may not increase much?
A
Adding any second species always guarantees high resilience, regardless of traits.
B
Functional and response diversity remain low because both crops share similar vulnerability to the same disturbance.
C
Closely related crops cannot compete, so both will become fully resistant to beetles.
D
The beetle will stop feeding because it can only locate fields with one species.
